我写的是
<?php
if (isset($_POST['delete'])):
$size = count($_POST['checkbox']);
for ($i=0; $i<=$size-1; $i++) {
$id = $_POST['checkbox'][$i];
$wpdb->query("DELETE FROM wp_submitted_form WHERE id =".$id);
}
header('Location: http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
endif;
?>
单击提交按钮时,会抛出错误消息:
Cannot modify header information - headers already sent by (output started at /home/wizcorea/public_html/wp-admin/includes/template.php:1657) in /home/wizcorea/public_html/wp-content/plugins/submitted-form/view.php on line 54
我希望在点击提交按钮后刷新该页面

使用PHP的ob_flush
功能。在代码顶部添加此功能。
<?php
ob_flush();
这将有效。

代替此代码:
header('Location: http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
使用此代码:
echo '<script>location.href="http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'].'"</script>';
