Question

我在一个页面中有很多forms，有一个按钮可以打开一个隐藏的文本编辑器，目的是根据user_id更新文本文件所以我遍历所有用户并获得许多这些：

<form action="admin/edittoken.php" method="POST">
    <td><a id="'.$result[0]['user_id'].'" onclick="toggle_visibility(\'feedDiv\');">
        <button onclick="toggle_visibility(\'feed\');" type="button">Feed
        </button><a/></td>
    <td><button class="btn btn-default" type="submit" name="password" >Apply Changes</button></td>
    <td><input name="first_name" class="smallInput" value="'.$result[0]['first_name'].'" type="text" /></td>
</form>

正如您所看到的，当我点击此链接时，每个表单中都有一个我显示id = feedDiv的div

<a id="'.$result[0]['user_id'].'" onclick="toggle_visibility(\'feedDiv\');">

<a>的id是用户ID，使用该数据，我可以提取正确的txt文件进行编辑

我的目标是：

获取请求显示div（user_id）
将该ID放在php for PDO之间查询并显示正确的txt文件

这是php

<div id="feedDiv">
    <form method="POST" action="admin/edittoken.php">
        <textarea id="feed" name="information">
            <?php $user=/ /the a Link Clicked Id Value is the user_id //need help
            here $filename=/ /equal to the PDO Result to get the right text file $handle=f
            open($filename, "r"); $contents=f read($handle, filesize($filename)); fclose($handle);
            echo $contents; ?>
        </textarea>
        <button class="btn  btn-primary yellow" type="submit" name="feed">Send Feed</button>
    </form>
</div>

到目前为止的Javascript ...

function toggle_visibility(id) {
    var e = document.getElementById(id);
    if (e.style.display == 'block') e.style.display = 'none';
    else e.style.display = 'block';
}

Answer 1

<a id="'.$result[0]['user_id'].'" onclick="toggle_visibility(\'feedDiv\', this.id);">


function toggle_visibility(id, user_id) {
       var e = document.getElementById(id);
       if(e.style.display == 'block')
          e.style.display = 'none';
       else
          e.style.display = 'block';

$.post("userdetail.php", { userid: user_id },
  function(data){
    $('#'+id).html(data);
  });

}

userdetail.php包含：

<form method="POST" action="admin/edittoken.php"> 
    <textarea id="feed" name="information">
    <?php
            $user = $_POST['userid']//the a Link Clicked Id Value is the user_id //need help here
            $filename = //equal to the PDO Result to get the right text file
                    $handle = fopen($filename, "r");
            $contents = fread($handle, filesize($filename));
            fclose($handle);
            echo $contents;
        ?>
        </textarea>
        <button class="btn  btn-primary yellow" type="submit" name="feed"  >Send Feed</button>  
        </form>

///// 你的占位符就像

<div id="feedDiv" ></div>

如何在点击php时从链接发送id值
