我想将一条消息保存在PHP变量中，并用已返回的其他数组变量发回。例如，我在PHP代码中发生了一些错误检查，并想要一个字符串变量，并将特定的消息发送回我的javascript中使用。将字符串变量从PHP发送回数组变量的ajax ...？

这里是PHP：

include('config-searchres.php');

$term = $_POST['resid'];

$sql = mysql_query("SELECT * FROM ap_form_8 WHERE id = '$term'"); //select first name (element_1_1) from form #8

if ($row = mysql_fetch_array($sql)){ //if reservation number exists

if ($row['element_11'] != 'Cancelled'){ //if reservation has not already been cancelled

if (strtotime($row['element_3']) >= strtotime(date("Y-m-d"))){ //if reservation has not already passed date

echo json_encode($row);

}

else //Reservation already passed (old reservation)

{

echo 'passed';

}

}

else //Reservation already cancelled

{

echo 'cancelled';

}

}

else //Reservation not found

{

echo 'not found';

}

mysql_close();

?>

正如你可以看到，有3级不同的消息，“合格”，“取消”和“未找到” ......如果这些条件之一存在，我想把这个字符串发回给我的JavaScript，所以我可以在DIV中显示它。不过，我也想发送$ row数据。

我的javascript：

$(document).ready(function(){

resetForms('reservation');

$('#form-reservation').submit(function(event){

event.preventDefault(); //the page will no longer refresh on form submit.

var resCheck = $(this).find('input[class="reservationid"]').val(); //now we have the reservation ID, let's perform our check.

$.ajax({

url: 'inc/searchres.php',

type: 'POST',

data: 'resid='+resCheck,

success: function(data){ //data is all the info being returned from the php file

$('#reservation-id').val(resCheck); //add read ID back into text box

var jsonData = $.parseJSON(data); //parse returned JSON data so we can use it like data.name, data.whatever

//****I wanted the line just below this to display the appropriate message sent back from the PHP****

$("#res-message").html('Reservation ID Located, Information is displayed below');

$('#json-reservation').populate({personal_first_name:jsonData['element_1_1'],personal_last_name:jsonData['element_1_2'],personal_phone_1:jsonData['element_7'],personal_email:jsonData['element_2'],reservation_status:jsonData['ADD THIS CELL'], reservation_id:jsonData['id'], reservation_date:jsonData['element_3'],reservation_time:jsonData['element_4'],reservation_party:jsonData['element_5'],reservation_special_request:jsonData['element_6'],reservation_using_coupon:jsonData['element_9'],reservation_coupon_code:jsonData['element_10'],reservation_status:jsonData['element_11']});

$("#res-cancel-message").html('');

},

error: function(){

$("#res-message").html('There was an error with your request');

$("#res-cancel-message").html('');

}

});

});

});

我打上，我填充在这个时候一个静态的消息DIV星号，这是我会填充从PHP消息的线。有任何想法吗？
