因此,我试图运行一个PHP脚本,如果将某个文本元素拖到可放置区域,则会将数据库中的已删除字段设置为poplulate。
目前我有可放置区:
<div class="dropbin" id="dropbin" >
<span class="fa fa-trash-o noSelect hover-cursor" style="font-size: 20pt; line-height: 225px;"> </span>
</div>
以及可拖动文字:
<div id='dragme' data-toggle='modal' data-target='#editNoteNameModal' class='display-inline'>" . $data['NoteName'] . "</div>
我遇到问题的区域是:
$("#dropbin").droppable
({
accept: '#dragme',
hoverClass: "drag-enter",
drop: function(event)
{
var noteid = <?php if(isset($_POST['noteid'])){ echo $_POST['noteid'];} ?>;
var deletedby = <? if(isset($_SESSION['username'])){ echo $_SESSION['username'];} ?>
var data = {noteid1: noteid, deletedby1: deletedby};
if (confirm('Delete the note?')==true)
{
$('#dragme').hide();
debugger
$.ajax({
type: 'POST',
url: 'deleteNote.php',
datatype: 'json',
data: data,
success: function(result)
{
alert("Success");
}
});
window.location = "http://discovertheplanet.net/general_notes.php";
}
else
{
window.location = "http://discovertheplanet.net/general_notes.php";
}
}
});
编辑:我收到错误的行是:
var noteid = <?php if(isset($_POST['noteid'])){ echo $_POST['noteid'];} ?>;
我目前正在获取一个&#34;意外的令牌;&#34; 并阻止了droppable工作。
只是旁注,如果我在没有变量的情况下运行它,它会触及除了以下所有内容:
url: 'deleteNote.php',
同样在deleteNote.php里面,这有助于:
<?php
include "connectionDetails.php";
?>
<?php
if (isset($_POST['noteid1'], $_POST['deletedby1']))
{
$noteid2 = $_POST['noteid1'];
$deletedby2 = $_POST['deletedby1'];
// echo "Hello...". $noteid;
$stmt = "UPDATE Notes SET Deleted = GETDATE() WHERE NoteID = (?)";
$params = array($noteid2);
$stmt = sqlsrv_query($conn, $stmt, $params);
if ($stmt === false)
{
die( print_r(sqlsrv_errors(), true));
}
}
else
{
echo "No Data";
}
?>
(我还没有在数据库中删除过,忽略了这一点)
有没有人可以帮助我让这个工作?
答案 0 :(得分:5)
尝试在这些行中添加引号,并在php
后面的第二行添加<?
:
var noteid = "<?php if(isset($_POST['noteid'])){ echo $_POST['noteid'];} ?>";
var deletedby = "<?php if(isset($_SESSION['username'])){ echo $_SESSION['username'];} ?>";
或
var noteid = "<?=isset($_POST['noteid']) ? $_POST['noteid'] : "" ?>";
var deletedby = "<?=isset($_SESSION['username']) ? $_SESSION['username'] : "" ?>";
