下面这个程序在你输入id后就把那个id的数据列出来。然后你就可以修改后写入了. <html> <body> <h1>数据库的数据更新</h1> <? if(isset($id)) { if(!mysql_connect("localhost","用户名","密码")) {echo"无法联接数据库"; exit(); } if(isset($url)) { $query="update $jpg set id='$id',url='$url',mess='$mess', fromx='$fromx',url1='$url1',mess1='$mess1',fromx1='$fromx1',url2='$url2', mess2='$mess2',fromx2='$fromx2',url3='$url3',mess3='$mess3',fromx3='$fromx3' where id='$id'" ; $result=mysql_db_query("elong",$query); //执行写入
if (!$result) {echo "发生错误!"; exit(); } echo "$id 已经更新!<br><br>"; echo "<table>n <tr>n <td>ID<td>$id</tr>n <tr>n <td>url地址<td>$url</tr>n <tr>n <td>小图<td>$mess</tr>n <tr>n <td>说明<td>$fromx</tr>n <tr>n <td>url地址1<td>$url1</tr>n <tr>n <td>小图1<td>$mess1</tr>n <tr>n <td>说明1<td>$fromx1</tr>n <tr>n <td>url地址2<td>$url2</tr>n <tr>n <td>小图2<td>$mess2</tr>n <tr>n <td>说明2<td>$fromx2</tr>n <tr>n <td>url地址3<td>$url3</tr>n <tr>n <td>小图3<td>$mess3</tr>n <tr>n <td>说明3<td>$fromx3</tr>n </table>n"; echo "<a href='set.htm'>回到首页</a>"; exit(); } $query="SELECT id,url,mess,fromx,url1,mess1,fromx1,url2,mess2,fromx2,url3,mess3,fromx3 from $jpg where id='$id'" ; $result=mysql_db_query("elong",$query); if (!$result) {echo "发生错误!"; exit(); } $r=mysql_fetch_array($result); $id = $r["id"]; $url = $r["url"]; $mess = $r["mess"]; $fromx = $r["fromx"]; $url1 = $r["url1"]; $mess1 = $r["mess1"]; $fromx1 = $r["fromx1"]; $url2 = $r["url2"]; $mess2 = $r["mess2"]; $fromx2 = $r["fromx2"]; $url3 = $r["url3"]; $mess3 = $r["mess3"]; $fromx3 = $r["fromx3"]; echo" <form action='ww.php' method='post'>n <table>n <tr>n <td>ID:<td> <input type=text name='id' value='$id'></tr>n <tr>n <td>类形:<td> <input type=text name='jpg' value='$jpg'></tr>n <tr>n <td>图片url地址:<td> <input type=text name='url' size='100' value='$url'></tr>n <tr>n <td>说明:<td> <input type=text name='mess' size='100' value='$mess'></tr>n <tr>n <td>来自:<td> <input type=text name='fromx' size='100' value='$fromx'></tr>n <tr>n <td>图片url地址:<td> <input type=text name='url1' size='100' value='$url1'></tr>n <tr>n <td>说明:<td> <input type=text name='mess1' size='100' value='$mess1'></tr>n <tr>n <td>来自:<td> <input type=text name='fromx1' size='100' value='$fromx1'></tr>n <tr>n <td>图片url地址:<td> <input type=text name='url2' size='100' value='$url2'></tr>n <tr>n <td>说明:<td> <input type=text name='mess2' size='100' value='$mess2'></tr>n <tr>n <td>来自:<td> <input type=text name='fromx2' size='100' value='$fromx2'></tr>n <tr>n <td>图片url地址:<td> <input type=text name='url3' size='100' value='$url3'></tr>n <tr>n <td>说明:<td> <input type=text name='mess3' size='100' value='$mess3'></tr>n <tr>n <td>来自:<td> <input type=text name='fromx3' size='100' value='$fromx3'></tr>n </table>n <input type=submit value='更新'>n </form>n"; } else {?> <h3>请输放需要更改的id:</h3> <center><form action='ww.php' method='post'> <br> 动漫桌布 <input type="radio" name="jpg" value="jpg" checked> 平分秋色水彩画 <input type="radio" name="jpg" value="jpg1"> 明星写真 <input type="radio" name="jpg" value="jpg2"> 广告创意 <input type="radio" name="jpg" value="jpg3"> 其它类 <input type="radio" name="jpg" value="jpg4"> <br> <input type=text name='id'> <input type=submit value='查询'> </form></center>
