Question

我很难用多个复选框删除来解决我的问题。有人可以指导我解决方案吗？这里应该发生的是用户可以勾选方框并单击删除按钮来删除勾选的方框。不幸的是，我的代码似乎不起作用;你能为我指出正确的方向吗？

Answer 1

此HTML：

echo '<div id="post1"><p class="postParagraph">Post ID No.'.$idNoz.'<br />'.$postz.' at '.$timez.' seconds mark</p><input type="checkbox" name="checkbox[]" id="checkbox[]" value="'.$idNoz.'"</input></div>';

应该是：

echo '<div id="post1"><p class="postParagraph">Post ID No.'.$idNoz.'<br />'.$postz.' at '.$timez.' seconds mark</p><input type="checkbox" name="checkbox[]" id="checkbox[]" value="'.$idNoz.'" /></div>';

else if($_POST['btnDelete'] == "Delete")上的此查询应为：

$sql = 'DELETE FROM `'.$tbl_name.'` WHERE `PostID`='.(int)$value;

PHP多个CheckBox删除
