对于这种特殊的用户能力,我想问两件事。第一个是如何在用户单击按钮时删除一行。第二个是....这是个好主意吗?我怎样才能为某人创造一个安全的环境来做到这一点。这是我到目前为止所得到的:
<?php
include_once "db_conx.php";
if($_POST['wall'] == "post") {
//open if($_POST['wall'] == "post")
$id = mysqli_real_escape_string($db_conx, trim($_POST['id1']));
if($id == " ")
{
exit();
}
else
$sql = "SELECT FROM courseprogress WHERE userid='$id' LIMIT 1";
$results = mysqli_query($db_conx, $sql);
$sidebar = mysqli_num_rows($results);
if($sidebar > 0) {
//close if($sidebar > 0)
while($row = mysqli_fetch_assoc($results))
{
$sql = mysqli_query("DELETE FROM courseprogress WHERE userid='$id'");
$results = mysqli_query($db_conx, $sql);
}
//close if($sidebar > 0)
}
else
{
echo 'Already Complete!';
echo "<pre>";
var_dump($sql);
echo "</pre><br>";
}
//close if($_POST['wall'] == "post")
}
?>
现在我正在转储变量,但似乎无法正确获取我的 id 变量。
从某种意义上说,这个想法是“重新开始”。该表包含用户进度和设置。一旦他们决定他们需要重新开始,他们将被允许通过简单地删除该行来重新开始。当再次开始时,将再次创建该行。

我尝试使用的小型脚本是:
<div class="userInfoContain"><div class="positionRight"><div id="form"> <form><div class="submit"><input type="hidden" id="id" value="'.$id.'" /><input type="submit" name="button" id="button" value="Start Over" onclick="return false" onmousedown="javascript:wall();"/><img src="images/loading.gif" alt="" width="15" height="15" id="loadingstart" /></div></form></div></div></div>
<script type="text/javascript">
$(document).ready(function(){
$('#loadingstart').hide();
});
function wall(){
$('#loadingstart').show();
var id = $('#id').val();
var URL = "./includes/start-over-user.php"; /////post.php will be equal the variable "comment"
$.post(URL,{wall:"post",id1:id},function(data){//parameter wall will be equal "post", name1 will be equal to the var "name" and comment1 will be equal to the var "comment"
$("#result").prepend(data).show();// the result will be placed above the the #result div
$('#loadingstart').hide();
});
}
</script>
