八、发表博客

（1）、界面实现file.php

<tr> <td colSpan=3 valign="baseline" style="BACKGROUND-IMAGE: url( images/bg.jpg); VERTICAL-ALIGN: middle; HEIGHT: 450px; TEXT-ALIGN: center"><table width="100%" height="100%"  border="0" cellpadding="0" cellspacing="0"><tr><td height="451" align="center" valign="top"><!-- 发表文章 --><table width="640"  border="0" cellpadding="0" cellspacing="0"><tr><td width="613" height="223" align="center"><br>
<span style="white-space:pre">         </span><table width="500" border="0" cellpadding="0" cellspacing="0"><tr><td>
<span style="white-space:pre">     </span>    <form  name="myform" method="post" action="check_file.php?flag=<?php echo $flag; if($flag){echo "&id=".$_GET['file_id'];}?>">
<span style="white-space:pre">     </span>    <table width="630" border="1" cellpadding="3" cellspacing="1" bordercolor="#D6E7A5"><tr><td class="i_table" colspan="2"> <span class="tableBorder_LTR">加入博客文章</span></td></tr><tr><td valign="top" align="right" width="14%">博客主题：<br></td><td width="86%"><input name="txt_title" type="text" id="txt_title" size="68" value="<?php if($flag){echo $title;}?>"></td></tr><tr><td align="right" width="14%">文字编辑区：</td><td width="86%"><img src=" images/UBB/B.gif" width="21" height="20" onClick="bold()">&nbsp;<img src=" images/UBB/I.gif" width="21" height="20" onClick="italicize()">&nbsp;<img src=" images/UBB/U.gif" width="21" height="20" onClick="underline()">
<span style="white-space:pre">             </span>            字体<select name="font" class="wenbenkuang" id="font" onChange="showfont(this.options[this.selectedIndex].value)"><option value="宋体" selected>宋体</option><option value="黑体">黑体</option><option value="隶书">隶书</option><option value="楷体">楷体</option></select>字号<span class="pt9"><select name=size class="wenbenkuang" onChange="showsize(this.options[this.selectedIndex].value)"><option value=1>1</option><option value=2>2</option><option value=3 selected>3</option><option value=4>4</option><option value="5">5</option><option value="6">6</option><option value="7">7</option></select>颜色<select onChange="showcolor(this.options[this.selectedIndex].value)" name="color" size="1" class="wenbenkuang" id="select"><option selected>默认颜色</option><option style="color:#FF0000" value="#FF0000">红色热情</option><option style="color:#0000FF" value="#0000ff">蓝色开朗</option><option style="color:#ff00ff" value="#ff00ff">桃色浪漫</option><option style="color:#009900" value="#009900">绿色青春</option><option style="color:#009999" value="#009999">青色清爽</option><option style="color:#990099" value="#990099">紫色拘谨</option><option style="color:#990000" value="#990000">暗夜兴奋</option><option style="color:#000099" value="#000099">深蓝忧郁</option><option style="color:#999900" value="#999900">卡其制服</option><option style="color:#ff9900" value="#ff9900">镏金岁月</option><option style="color:#0099ff" value="#0099ff">湖波荡漾</option><option style="color:#9900ff" value="#9900ff">发亮蓝紫</option><option style="color:#ff0099" value="#ff0099">爱的暗示</option><option style="color:#006600" value="#006600">墨绿深沉</option><option style="color:#999999" value="#999999">烟雨蒙蒙</option></select></span></td></tr><tr><td align="right" width="14%">文章内容：</td><td width="86%">
<span style="white-space:pre">             </span>    <div class="file"><span style="white-space:pre">                     </span>
<span style="white-space:pre">                 </span><textarea name="file" cols="75" rows="20" id="file" style="border:0px;width:520px;"><?php if($flag){echo $content;}?></textarea>
<span style="white-space:pre">             </span>    </div>
<span style="white-space:pre">         </span>    </td></tr><tr align="center"><td colspan="2"><input name="btn_tj" type="submit" id="btn_tj" value="提交" onClick="return check();">                          &nbsp;<input name="btn_cx" type="reset" id="btn_cx" value="重写"></td></tr></table>
<span style="white-space:pre">         </span></form>
<span style="white-space:pre">         </span></td></tr></table></td></tr></table>            </td></tr></table></td> </tr> 

编辑文章时各个选项使用js实现：UBBCode.js

helpstat = false;
basic = false;
function AddText(NewCode) {document.all("file").value+=NewCode
}
function showsize(size) {if (helpstat) {alert("文字大小标记\n设置文字大小.\n可变范围 1 - 6.\n 1 为最小 6 为最大.\n使用方法: <size="+size+">这是 "+size+" 文字</size>");} else if (basic) {AddTxt="<font size="+size+"></font>";AddText(AddTxt);} else {                       txt=prompt("大小 "+size,"文字"); if (txt!=null) {             AddTxt="<font size="+size+">"+txt;AddText(AddTxt);AddTxt="</font>";AddText(AddTxt);}        }
}function bold() {if (helpstat) {alert("加粗标记\n使文本加粗.\n使用方法: <b>这是加粗的文字</b>");} else if (basic) {AddTxt="<b></b>";AddText(AddTxt);} else {  txt=prompt("文字将被变粗.","请在这里输入要加粗的文字！

（2）后台加入到数据库实现check_file.php

<?

php session_start(); require_once 'Conn/SqlHelper.class.php'; $flag = $_GET['flag']; if($flag!=2){ $txt_title = $_POST['txt_title']; $file = $_POST['file']; $author = $_SESSION['username']; $date = date("Y-m-d H:i:s"); } $sqlHelper = new SqlHelper(); if($flag==0){ $sql = "insert into tb_article(title,content,author,now)values('$txt_title','$file','$author','$date')"; } $res = $sqlHelper->execute_dml($sql); if($res==1){ echo "<script>alert('操作成功。');</script>"; echo "<script>window.location.href='myfiles.php';</script>"; }else{ echo "<script>alert('对不起失败了！

');</script>"; echo "<script> history.go(-1);</script>"; } ?>
