Ajax脚本，无法获取PHP $ _GET变量

我很难用Ajax脚本获取PHP $ _GET变量，目标是使用相同的脚本更新MySql表。这是我用于获取和显示数据的PHP / HTML脚本：

session_start();
require_once ('dbconnect.php');

$query = mysql_query("SELECT p_id, p_name, p_authors, p_corresponding, p_email, p_cauthor, p_abstract, p_keywords, p_jname, p_date FROM papers INNER JOIN users ON papers.user_id = users.user_id WHERE p_url = '$val' AND username='{$_SESSION['user']}'");
$last = mysql_num_rows($query);
$output1 = "";
$outarray1 = array();
  if ($last > 0) {
    while ($output1 = mysql_fetch_array($query)) {
    $outarray1[] = $output1;
      if(is_array($outarray1)){
        foreach($outarray1 as $values){
        $id = $values['p_id'];
        $paper = $values['p_name'];
        $author = $values['p_authors'];
        $corresponding = $values['p_corresponding'];
        $mail = $values['p_email'];
        $coauthors = $values['p_cauthor'];
        $abstract = $values['p_abstract'];
        $keywords = $values['p_keywords'];
        $journal = $values['p_jname'];
        $date = $values['p_date'];
}
  }
    }   
      } 
echo <<<HERE
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="memberModalLabel" aria-hidden="true">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span><span class="sr-only">Close</span></button>
<h4 class="modal-title" id="memberModalLabel">Edit Paper Details</h4>
</div>
</div>                           
<table class="table table-striped table-bordered">
  <thead>
    <tr>
    <th>ID</th>
    <th>Paper</th>
    <th>Author</th>
    <th>Corresponding author</th>
    <th>Mail</th>
    <th>Co-authors</th>
    <th>Abstract</th>
    <th>Keywords</th>
    <th>Journal</th>
    <th>Date</th>
    </tr>
        </thead>
   <tbody>
    <tr>
        <td>{$id}</td>
        <td>{$paper}</td>
        <td>{$author}</td>
        <td>{$corresponding}</td>
        <td>{$mail}</td>
        <td>{$coauthors}</td>
        <td>{$abstract}</td>
        <td>{$keywords}</td>
        <td>{$journal}</td>
        <td>{$date}</td>
    <td><a class="btn btn-small btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="<?php echo $id; ?>">Edit</a></td>                  
   </tr>
</tbody>
</table>

这是同一页面上的AJAX / JQuery脚本，用于使用$ _GET方法从表中获取ID变量，但问题是，当单击编辑按钮时，$ _GET变量不会显示在URL中，也不会在editfile中被选中页面，我只能看到＆＃34;编辑纸张详细信息＆＃34;标题，下面的空格是空的，它应该显示用于编辑记录的字段：

<script>
$('#exampleModal').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget) // Button that triggered the modal
var recipient = button.data('whatever') // Extract info from data-* attributes
var modal = $(this);
var dataString = 'id=' + recipient;
$.ajax({
    type: "GET",
    url: "editdata.php",
    data: dataString,
    cache: false,
    success: function (data) {
    console.log(data);
    modal.find('.ct').html(data);
    },
    error: function(err) {
    console.log(err);
    }
    });  
    })
</script>

这是editfile脚本：

<?php
session_start();
require_once ('dbconnect.php');
?>

<html lang="en">
<head>
    <link href="css/bootstrap.min.css" rel="stylesheet">

    mysql_query($qry) or die("Error !".mysql_error());
    header("Location: home.php");
}

 ?>

有什么建议吗？

答案 0 :(得分：0)

我假设你的＆＃34;编辑文件脚本＆＃34;是来自你的ajax的editdata.php。

1）我看到你试图通过GET传递ID的位置，但是你从哪里获得所有发布的数据？

2）使用GET时，您不必再指定它的GET数据，只需将其附加到URL ... 

url: "editdata.php?"+dataString,
