我有困難的時間獲取帶有Ajax腳本的PHP $ _GET變量，目標是使用相同的腳本更新MySql表。這是我用來獲取和顯示數據PHP/HTML腳本：
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 = $values['p_date'];
}
}
}
}
echo <<<HERE
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="memberModalLabel" aria-hidden="true">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<h4 class="modal-title" id="memberModalLabel">Edit Paper Details</h4>
</div>
</div>
<table class="table table-striped table-bordered">
<thead>
<tr>
<th>ID</th>
<th>Paper</th>
<th>Author</th>
<th>Corresponding author</th>
<th>Mail</th>
<th>Co-authors</th>
<th>Abstract</th>
<th>Keywords</th>
<th>Journal</th>
<th>Date</th>
</tr>
</thead>
<tbody>
<tr>
<td>{$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 $id; ?>">Edit</a></td>
</tr>
</tbody>
</table>
這是同一個頁面上的AJAX/jQuery腳本從表中讀取ID變量，$ _ GET方法，但問題是，當編輯按鈕點擊時，$ _ GET變量沒有URL顯示，也沒有在EDITFILE頁面被拾起，我只能看到「編輯文件細節」稱號，下方空間是空的，它應該顯示爲編輯記錄字段：
<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>
這是編輯文件腳本：
<?php
session_start();
require_once ('dbconnect.php');
?>

mysql_query($qry) or die("Error !".mysql_error());

有什麼建議嗎？
只是一個警告：你正在使用PHP的'的mysql_query（） '和相關功能。請注意，此API已棄用（並且將在下一個PHP版本中完全刪除）。您應該考慮將代碼切換爲使用PDO或mysqli庫。 – Simba
