In this third and final part of our eBay Trading API series, we’ll be building the product adding functionality into our application.

在我们的eBay交易API系列的第三个也是最后一个部分中，我们将构建将功能添加到我们的应用程序中的产品。

创造新产品 (Creating new Products)

Now that we’re done with the store settings, we can begin with writing the code for the controller that would handle the creation of products. Under the controllers directory, create a new file and name it Product.php.

既然我们已经完成了商店设置，那么我们就可以开始为处理产品创建的控制器编写代码。 在controllers目录下，创建一个新文件，并将其命名为Product.php 。

<?php
class Product extends \SlimController\SlimController{
}

Next, create the newAction method. This will render the new.twig file under the templates/product directory. This is the view that renders the form for creating new products.

接下来，创建newAction方法。 这将在templates/product目录下呈现new.twig文件。 这是呈现用于创建新产品的表单的视图。

public function newAction(){
$page_data = array(
'is_productpage' => 'true'
);
$this->render('product/new', $page_data);
}

Next create the view:

接下来创建视图：

{% extends "/base.twig" %}
{% block content %}
{{ parent() }}
<div class="row">
<div class="col-md-4">
<div class="alert alert-{{ flash.message.type }}">
{{ flash.message.text }}
{% for r in flash.message.data %}
<li>{{ r[0] }}</li>
{% endfor %}
</div>
</div>
</div>
<div class="row">
<div class="col-md-6">
<form class="form-horizontal" method="POST" action="{{ baseUrl }}/products/create">
<fieldset>
<legend>Create new Product</legend>
<div class="form-group">
<label for="title" class="col-lg-2 control-label">Title</label>
<div class="col-lg-10">
<input type="text" class="form-control" id="title" name="title" value="{{ flash.form.title }}">
</div>
</div>
<div class="form-group">
<label for="category" class="col-lg-2 control-label">Category</label>
<div class="col-lg-10" id="categories-container">
</div>
</div>
<div class="form-group">
<label for="price" class="col-lg-2 control-label">Price</label>
<div class="col-lg-10">
<input type="text" class="form-control" id="price" name="price" value="{{ flash.form.price }}">
</div>
</div>
<div class="form-group">
<label for="quantity" class="col-lg-2 control-label">Quantity</label>
<div class="col-lg-10">
<input type="text" class="form-control" id="quantity" name="quantity" value="{{ flash.form.quantity }}">
</div>
</div>
<div class="form-group">
<label for="brand" class="col-lg-2 control-label">Brand</label>
<div class="col-lg-10">
<input type="text" class="form-control" id="brand" name="brand" value="{{ flash.form.brand }}">
</div>
</div>
<div class="form-group">
<label for="description" class="col-lg-2 control-label">Description</label>
<div class="col-lg-10">
<textarea class="form-control" rows="3" id="description" name="description" value="{{ flash.form.description }}">{{ flash.form.description }}</textarea>
</div>
</div>
<div class="form-group">
<div class="col-lg-10 col-lg-offset-2">
<button type="submit" class="btn btn-primary">Add Product</button>
</div>
</div>
</fieldset>
</form>
</div>
<div class="col-md-6">
<h5>Upload Photos</h5>
<form action="{{ baseUrl }}/upload" method="POST" class="dropzone" id="photosdropzone" enctype="multipart/form-data"></form>
</div>
</div>
{% include 'partials/categories.html' %}
{% endblock %}

Breaking it down, at the beginning is where we output the alert message. We’ll pass along the values for this later on when we add the code for creating products. flash is a global variable where session data that we pass along is temporarily saved:

分解它，一开始就是我们输出警报消息的地方。 我们稍后会在添加用于创建产品的代码时传递其值。 flash是一个全局变量，临时存储我们传递的会话数据：

<div class="alert alert-{{ flash.message.type }}">
{{ flash.message.text }}
{% for r in flash.message.data %}
<li>{{ r[0] }}</li>
{% endfor %}
</div>

Next is the product title and other required product details. Take note that only the product title, description, quantity, price, and a product image are required in most cases. Here, we’ve added brand because in some cases it’s required. The general term for this kind of field is a conditional field. It usually depends on the category of the product whether it’s required or not. Some categories require more fields than others so be sure to check the documentation on the AddItem API Call to make sure you’re not missing anything.

接下来是产品标题和其他必需的产品详细信息。 请注意，在大多数情况下，仅需要产品标题，描述，数量，价格和产品图片。 在这里，我们添加了品牌，因为在某些情况下是必需的。 这种字段的总称是条件字段。 是否需要通常取决于产品类别。 某些类别比其他类别需要更多的字段，因此请务必检查AddItem API调用上的文档以确保您没有遗漏任何内容。

<input type="text" class="form-control" id="title" name="title" value="{{ flash.form.title }}">

For the product category, we’re going to load it later on via AJAX since it will depend on the product title entered by the user.

对于产品类别，我们稍后将通过AJAX加载它，因为它取决于用户输入的产品标题。

<label for="category" class="col-lg-2 control-label">Category</label>
<div class="col-lg-10" id="categories-container">
</div>

Next is the form that the user will use for uploading the product images:

接下来是用户用来上传产品图片的表单：

<form action="{{ baseUrl }}/upload" method="POST" class="dropzone" id="photosdropzone" enctype="multipart/form-data"></form>

This uses the /upload route for processing the uploaded files. Declare the method for processing this route in the Product class:

这使用/upload路由来处理上传的文件。 在“ Product类中声明处理此路线的方法：

public function uploadAction(){
$storage = new \Upload\Storage\FileSystem('uploads');
$file = new \Upload\File('file', $storage);
$new_filename = uniqid();
$file->setName($new_filename);
$_SESSION['uploads'][] = $new_filename . '.' . $file->getExtension();
$file->addValidations(array(
new \Upload\Validation\Mimetype(array('image/png', 'image/gif', 'image/jpg')),
new \Upload\Validation\Size('6M')
));
$errors = array();
try{
$file->upload();
}catch(Exception $e){
$errors = $file->getErrors();
}
$response_data = array(
'errors' => $errors
);
echo json_encode($response_data);
}

Breaking the uploadAction() method down, first we specify the upload path. In this case we’re using the uploads directory. Make sure you give it the necessary directory permissions so we can actually upload files to it:

uploadAction()方法，首先我们指定上传路径。 在这种情况下，我们使用的是uploads目录。 确保您为其授予了必要的目录权限，以便我们可以实际将文件上传到该目录：

$storage = new \Upload\Storage\FileSystem('uploads');

Next, we specify the field we use for uploading files. Going back to the form for uploading, we didn’t specify any <input type="file"> fields in there. That’s because we don’t need to. By default dropzone uses file as the default field name for uploading files so we specify it as the first argument for the File method, the second argument is the storage which we created earlier:

接下来，我们指定用于上传文件的字段。 回到上载表格，我们没有在其中指定任何<input type="file">字段。 那是因为我们不需要。 默认情况下，dropzone使用file作为上传文件的默认字段名称，因此我们将其指定为File方法的第一个参数，第二个参数是我们之前创建的存储：

$file = new \Upload\File('file', $storage);

Next, we give the file a unique name. You can be creative here if you want, but if you’re not feeling creative then just use the uniqid() method to generate a unique file name:

接下来，我们为文件指定一个唯一的名称。 如果需要，您可以在这里发挥创造力，但是如果您不觉得有创造力，则只需使用uniqid()方法生成唯一的文件名：

$new_filename = uniqid();
$file->setName($new_filename);

Push the file name into the uploads session item so we can use it later on.

将文件名推送到上uploads会话项中，以便我们稍后使用。

$_SESSION['uploads'][] = $new_filename . '.' . $file->getExtension();

Next, we add some file validation. We just tell it to only accept png, gif, and jpg images, and the max file size should only be 6Mb.

接下来，我们添加一些文件验证。 我们只是告诉它仅接受png，gif和jpg图片，并且最大文件大小应仅为6Mb。

$file->addValidations(array(
new \Upload\Validation\Mimetype(array('image/png', 'image/gif', 'image/jpg')),
new \Upload\Validation\Size('6M')
));

Lastly, we try to upload the file and assign any errors we get and return them to the client side. But we won’t really be making use of this error on the client side since dropzone already has us covered. It displays an x mark for the uploaded file if the file didn’t pass the validation:

最后，我们尝试上传文件并分配所有错误，然后将其返回给客户端。 但是我们真的不会在客户端使用此错误，因为dropzone已经覆盖了我们。 如果文件未通过验证，它将显示上载文件的x标记：

$errors = array();
try{
$file->upload();
}catch(Exception $e){
$errors = $file->getErrors();
}
$response_data = array(
'errors' => $errors
);
echo json_encode($response_data);

Going back to the template for adding new products, we include a partial. This is the template that will be used for showing the suggested product categories.

回到添加新产品的模板，我们包括一个部分。 这是用于显示建议的产品类别的模板。

{% include 'partials/categories.html' %}

It contains the following:

它包含以下内容：

{% raw %}
<script id="categories-template" type="text/x-handlebars-template">
{{#each categories}}
<div class="radio">
<label>
<input type="radio" name="category_id" id="category_id" value="{{id}}">
{{name}}
</label>
</div>
{{/each}}
</script>
{% endraw %}

In the above template, we’re using Handlebars. Its syntax collides with twig syntax so we have to wrap it in {% raw %} tags to make sure twig doesn’t parse it.

在上面的模板中，我们使用的是车把。 它的语法与Twig语法冲突，因此我们必须将其包装在{% raw %}标记中，以确保twig不会解析它。

Next, create the dropzone-options.js file under the /assets/js directory and add the following:

接下来，在/assets/js目录下创建dropzone-options.js文件，并添加以下内容：

(function(){
Dropzone.options.photosdropzone = {
acceptedFiles: "image/*",
autoProcessQueue: true,
uploadMultiple: false,
maxFiles: 5
};
})();

That allows us to specify the options for the dropzone. Here’s a breakdown of each option:

这使我们可以为dropzone指定选项。 以下是每个选项的细分：

• acceptedFiles – the type of file that can be uploaded.

  acceptedFiles –可以上传的文件类型。

• autoProcessQueue – a boolean value for specifying whether to process the queue immediately or not.

  autoProcessQueue –一个布尔值，用于指定是否立即处理队列。

• uploadMultiple – a boolean value for specifying whether to allow multiple file uploads. In this case we selected false but it doesn’t mean we can’t upload more than one image. It means that we can’t upload more than one image at the same time.

  uploadMultiple –一个布尔值，用于指定是否允许多个文件上传。 在这种情况下，我们选择了false但这并不意味着我们不能上传多个图像。 这意味着我们不能同时上传多个图像。

• maxFiles – an integer value for specifying the max number of files which can be uploaded.

  maxFiles –一个整数值，用于指定可以上传的最大文件数。

Next, create the new-product.js file and add the following:

接下来，创建new-product.js文件并添加以下内容：

(function(){
var categories_template = Handlebars.compile($("#categories-template").html());
$('#title').blur(function(){
var title = $(this).val();
$.post(
'/tester/ebay_trading_api/categories',
{
'title' : title
},
function(response){
var categories = JSON.parse(response);
var html = categories_template({'categories' : categories});
$('#categories-container').html(html);
}
);
});
})();

What the code above does is make a POST request every time the user tabs out of the product title field. The request then returns an array of objects containing the suggested categories based on the product title. The method which is used in this call is in the Product class. What it does is call the getSuggestedCategories() method in the Ebay class, passing in the product title as the argument. The response is then converted into a JSON string and echoed out:

上面的代码所做的是，每当用户从产品标题字段中跳出时，便发出POST请求。 然后，该请求将返回一个对象数组，其中包含基于产品标题的建议类别。 此调用中使用的方法在Product类中。 它的作用是在Ebay类中调用getSuggestedCategories()方法，并传入产品标题作为参数。 然后将响应转换为JSON字符串并回显：

public function categoriesAction(){
$suggested_categories = $this->app->ebay->getSuggestedCategories($_POST['title']);
echo json_encode($suggested_categories);
}

Open up the Ebay class and add the following method:

打开Ebay类并添加以下方法：

public function getSuggestedCategories($title){
$requestBody = '<?xml version="1.0" encoding="utf-8"?>
<GetSuggestedCategoriesRequest xmlns="urn:ebay:apis:eBLBaseComponents">
<RequesterCredentials>
<eBayAuthToken>' . $this->user_token . '</eBayAuthToken>
</RequesterCredentials>
<Query>' . $title . '</Query>
</GetSuggestedCategoriesRequest>';
$response = $this->request('GetSuggestedCategories', $requestBody);
$suggested_categories = array();
if($response->Ack == 'Success'){
foreach($response->SuggestedCategoryArray->SuggestedCategory as $category){
$suggested_categories[] = array(
'id' => json_decode(json_encode($category->Category->CategoryID), true)[0],
'name' => json_decode(json_encode($category->Category->CategoryName), true)[0]
);
}
}
return $suggested_categories;
}

What the method above does is make a request to the GetSuggestedCategories API method. This call accepts the product title as its argument, as passed in the Query field. If the call is successful, it returns an array of suggested categories. We just need to extract the category id and category name from the result it returns.

上面的方法所做的是向GetSuggestedCategories API方法发出请求。 此调用接受产品标题作为其参数，如在Query字段中传递的那样。 如果调用成功，则返回建议类别的数组。 我们只需要从返回的结果中提取类别ID和类别名称即可。

Now we’re ready to write the createAction method. This is where we save the product details into the database and create the product on ebay.

现在，我们准备编写createAction方法。 这是我们将产品详细信息保存到数据库中并在ebay上创建产品的地方。

public function createAction(){
$v = new Valitron\Validator($_POST);
$v->rule('required', array('title', 'category_id', 'price', 'quantity', 'brand', 'description'));
$v->rule('numeric', 'price');
$v->rule('integer', 'quantity');
if($v->validate()){
if($query = $this->app->db->prepare("INSERT INTO products SET title = ?, category_id = ?, price = ?, qty = ?, brand = ?, description = ?")){
$store_settings_result = $this->app->db->query("SELECT payment_profile, return_profile, shipping_profile, out_of_stock_control, get_it_fast, category_prefill,
category_mapping, condition_type, country_code_type, currency_code, dispatch_time, optimal_picturesize,
listing_duration, listing_type, item_location, postal_code, store_name, county,
street, ebay_website, shippingservice_priority, shipping_service, shippingservice_cost, shippingservice_additionalcost
FROM store_settings WHERE id = 1");
$store_settings = $store_settings_result->fetch_object();
$response = $this->app->ebay->addItem($store_settings, $_POST);
if($response->Ack == 'Success'){
$title = $_POST['title'];
$category_id = $_POST['category_id'];
$price = $_POST['price'];
$qty = $_POST['quantity'];
$brand = $_POST['brand'];
$description = $_POST['description'];
$query->bind_param("ssdiss", $title, $category_id, $price, $qty, $brand, $description);
$query->execute();
$this->app->flash('message', array('type' => 'success', 'text' => 'Product was created!'));
}else{
$long_message = json_decode(json_encode($response->Errors->LongMessage), true);
$this->app->flash('message', array('type' => 'danger', 'text' => $long_message[0]));
}
}
}else{
$this->app->flash('form', $_POST);
$this->app->flash('message', array(
'type' => 'danger',
'text' => 'Please fix the following errors',
'data' => $v->errors())
);
}
$this->app->redirect('/tester/ebay_trading_api/products/new');
}

Breaking it down. First, we declare a new instance of valitron, passing in all the values that are currently stored in the $_POST global variable:

分解。 首先，我们声明一个新的valitron实例，传入当前存储在$_POST全局变量中的所有值：

$v = new Valitron\Validator($_POST);

Next we add the rules. Basically all the fields are required, the price should be a numeric value, and the quantity should be an integer. We specified that using the rule method which takes up the actual rule as the first argument, and the name of the field as the second argument:

接下来，我们添加规则。 基本上所有字段都是必填字段，价格应为数字值，数量应为整数。 我们指定使用rule方法，该方法将实际规则作为第一个参数，并将字段名称作为第二个参数：

$v->rule('required', array('title', 'price', 'quantity', 'brand', 'description'));
$v->rule('numeric', 'price');
$v->rule('integer', 'quantity');

Next we validate using the validate() method. If this returns true then the validation passed, otherwise it didn’t. If it returns false then we take all the POST data and save it into the session along with the error messages returned by valitron.

接下来，我们使用validate()方法进行validate() 。 如果返回true则验证通过，否则验证通过。 如果它返回false那么我们将所有POST数据与valitron返回的错误消息一起保存到会话中。

$this->app->flash('form', $_POST);
$this->app->flash('message', array(
'type' => 'danger',
'text' => 'Please fix the following errors',
'data' => $v->errors())
);

If the validation passes, we retrieve the store settings from the database and supply them as an argument for the addItem() method along with the contents of the $_POST variable. The addItem() method creates the product on eBay. If the call is successful, we create a prepared statement for adding the details of the product in the database. Once that’s done we flash a message into the session saying that the product was created. If the call is not successful then we pass the response returned from the API along with a message that the product was not created.

如果验证通过，我们将从数据库中检索商店设置，并将其作为addItem()方法的参数以及$_POST变量的内容提供。 addItem()方法在eBay上创建产品。 如果调用成功，我们将创建一条准备好的语句，以将产品的详细信息添加到数据库中。 完成后，我们会向会话中闪现一条消息，说明该产品已创建。 如果调用失败，那么我们将传递从API返回的响应以及未创建产品的消息。

$store_settings_result = $this->app->db->query("SELECT payment_profile, return_profile, shipping_profile, out_of_stock_control, get_it_fast, category_prefill,
category_mapping, condition_type, country_code_type, currency_code, dispatch_time, optimal_picturesize,
listing_duration, listing_type, item_location, postal_code, store_name, county,
street, ebay_website, shippingservice_priority, shipping_service, shippingservice_cost, shippingservice_additionalcost
FROM store_settings WHERE id = 1");
$store_settings = $store_settings_result->fetch_object();
$response = $this->app->ebay->addItem($store_settings, $_POST);
if($response->Ack == 'Success'){
if($query = $this->app->db->prepare("INSERT INTO products SET title = ?, category_id = ?, price = ?, qty = ?, brand = ?, description = ?")){
$title = $_POST['title'];
$category_id = $_POST['category_id'];
$price = $_POST['price'];
$qty = $_POST['quantity'];
$brand = $_POST['brand'];
$description = $_POST['description'];
$query->bind_param("ssdiss", $title, $category_id, $price, $qty, $brand, $description);
$query->execute();
}
$this->app->flash('message', array('type' => 'success', 'text' => 'Product was created!'));
}else{
$this->app->flash('message', array('type' => 'danger', 'response' => $response, 'text' => 'Product was not created!'));
}
$this->app->redirect('/tester/ebay_trading_api/products/new');

Next, we’ll define the addItem method in the Ebay class. Define 2 parameters: $store_settings and $item_data. Inside the method declare a variable called $boolean_value. This allows us to convert the integer value 0 to a string false and the integer value 1 to a string true. We need this because the API only accepts either true or false for boolean parameters.

接下来，我们将在Ebay类中定义addItem方法。 定义2个参数： $store_settings和$item_data 。 在方法内部声明一个名为$boolean_value的变量。 这使我们能够将整数0转换为字符串false ，并将整数1转换为字符串true 。 我们需要这样做，因为API仅接受布尔参数为true或false 。

Next, assign the uploads session item to a variable. If you remember from earlier, this session item is where we pushed the filenames of the images that the user uploaded. Next is the $baseupload_url, this contains the base URL in which all uploaded images can be found. We need this because the UploadSiteHostedPictures API method only accepts a URL for uploading to ebay. This also means that you need to have an actual server that’s accessible via public internet. The UploadSiteHostedPictures method only accepts a single URL at a time so we have to loop through all the images and supply the actual URL as the value for the ExternalPictureURL field. If the request is successful we just append the new image URL that’s returned to the $picture_details variable. This will be used as one of the arguments passed to the call for actually creating the product on eBay.

接下来，将上uploads会话项分配给变量。 如果您还记得以前的版本，则此会话项是我们推送用户上传图像的文件名的地方。 接下来是$baseupload_url ，它包含可以在其中找到所有上载图像的基本URL。 我们需UploadSiteHostedPictures是因为UploadSiteHostedPictures API方法仅接受用于上传到ebay的URL。 这也意味着您需要有一台可以通过公共互联网访问的实际服务器。 UploadSiteHostedPictures方法一次只接受一个URL，因此我们必须遍历所有图像并提供实际URL作为ExternalPictureURL字段的值。 如果请求成功，我们只需将返回的新图像URL附加到$picture_details变量中即可。 这将用作传递给在eBay上实际创建产品的调用的参数之一。

Next, we make the request for adding the product to eBay. This can be done via either the AddItem method or the VerifyAddItem method. The AddItem method is the one that you would want in production, since it adds the product to ebay. If there are any fees, those are also applied. VerifyAddItem on the other hand acts like a sandbox method, it doesn’t actually add the item on ebay. You can use it if you want to test the AddItem call. No fees are applied when you call it, but it lets you know how much of a fee will be applied or if the request would actually be successful. Note that you don’t need to use the sandbox version of the API in order to call the VerifyAddItem method. You can use it even on the live version of the API.

接下来，我们请求将产品添加到eBay。 可以通过AddItem方法或VerifyAddItem方法来完成。 AddItem方法是您要在生产中使用的方法，因为它将产品添加到ebay。 如果有任何费用，这些费用也将适用。 另一方面， VerifyAddItem的作用类似于沙盒方法，实际上并没有在ebay上添加该项目。 如果要测试AddItem调用，可以使用它。 调用时不收取任何费用，但是它可以让您知道要收取多少费用或请求是否实际成功。 请注意，您无需使用API​​的沙盒版本即可调用VerifyAddItem方法。 您甚至可以在实时版本的API上使用它。

public function addItem($store_settings, $item_data){
$boolean_value = array('false', 'true');
$product_images = $_SESSION['uploads'];
$baseupload_url = 'http://somewhere.com/uploads/';
$picture_details = '';
if(!empty($product_images)){
foreach($product_images as $img){
$requestBody = '<?xml version="1.0" encoding="utf-8"?>

$uploaded_img = json_decode(json_encode($response->SiteHostedPictureDetails->PictureSetMember[3]->MemberURL), true);
$picture_details .= '<PictureURL>' . $uploaded_img[0] . '</PictureURL>';

$response = $this->request('AddItem', $requestBody);
return $response;
}

To make things clearer, here’s a breakdown of the parameters we passed to the AddItem request. Here we’re passing in the seller profiles. The only requirement for each seller profile is the profile ID. We already got those earlier when we fetched the store settings, so we simply get them from the database.

为了使事情更清楚，这是我们传递给AddItem请求的参数的细分。 在这里，我们传递了卖方资料。 每个卖家资料的唯一要求是资料ID。 在获取商店设置时，我们早已获得了这些设置，因此我们只需从数据库中获取它们即可。

结论 (Conclusion)

That’s it! In this tutorial we went through eBay’s Trading API. We have learned that we can talk to their API by acquiring a token for the user. We also walk through fetching the user settings, uploading images and adding products using the API. But that’s not all you can do with Ebay’s Trading API. It’s a pretty huge API and almost anything that you can think of that you can do with eBay with regards to selling products, you can also do with the API. So be sure to check the docs if you’re curious. You can check out the source code of the project we’ve built in this github repository.

而已！ 在本教程中，我们介绍了eBay的Trading API。 我们了解到，我们可以通过为用户获取令牌来与他们的API对话。 我们还将逐步介绍如何使用API​​获取用户设置，上传图片和添加产品。 但这不是您使用Ebay的Trading API所能做的全部。 这是一个非常庞大的API，您可以想到的几乎所有可以在eBay上进行销售的产品，也可以使用该API。 因此，如果您感到好奇，请务必检查文档 。 您可以检出我们在github存储库中构建的项目的源代码。
