PS: the codes is compilation of many tutorials PS: the processed button (delete) is the only problem here PS:代码是很多教程的汇编 PS:处理的按钮(删除)是这里唯一的问题
This the JS:这是JS:
<script>
//jQuery code here!
$(document).ready(function() {
var commentCount = 0;
$("#next").click(function() {
commentCount += 1;
$("#comments").load("load-comments.php", {
commentNewCount: commentCount
});
$("#processed").removeAttr('disabled');
$(this).attr('disabled', 'disabled');
});
$("#processed").click(function() {
var element = $("#comments");
var commentNewCount = element.attr("commentCount");
var info = 'commentCount=' +commentNewCount;
// alert(info);
if(confirm("Are you sure you want to delete this row?")){
$.ajax({
url: 'deleteuser.php',
type: 'post',
data: info,
success: function(){
}
});
$("#comments").parent().parent().fadeOut(500, function(){
$("#comments").remove();
});
}
return false;
});
$("#next").removeAttr('disabled');
$(this).attr('disabled', 'disabled');
});
</script>
phpcode in Next button:下一步按钮中的phpcode:
<?php
include 'dbh.php';
$commentNewCount = $_POST['commentNewCount'];
$sql = "SELECT * FROM comments LIMIT 1 OFFSET $commentNewCount";
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
while ($row = mysqli_fetch_assoc($result)) {
echo $row['id'];
}
} else {
echo "There are no queue!";
}
?>
phpcode in Processed button:已处理按钮中的 phpcode:
<?php
include 'dbh.php';
$userid =$_POST['id'];
$delete = mysqli_query($con, "DELETE FROM comments WHERE id=$commentNewCount");
if(!$delete){
echo "The queue Are already Delete" ;
}else{
echo "Success";
}
?>
In the frontend, you're using在前端,您正在使用
var info = 'commentCount=' +commentNewCount;
while in PHP code you're not getting it, you should use而在 PHP 代码中你没有得到它,你应该使用
$commentNewCount =$_POST['commentCount'];
in the PHP deletion code, there is no 'id' POST value在 PHP 删除代码中,没有 'id' POST 值
also, pay attention to variable names, it's not clear if you're deleting a comment or a user另外,请注意变量名称,不清楚您是删除评论还是用户
