php - php if statement based on previous click through url in Wordpress

Question

I'm trying to write an if statement based on the url of the previously click page_id

Something like this:

<?php 
$page_id = " the id or url of the page clicked to get to this page"
if($page_id){
    jr_register_form_jseeker( $redirect, $role ); 
}else{
    jr_register_form( $redirect, $role ); 
}
?>

I've looked at is_page() but that only seems to deal with the current page...?

Any ideas..?

Thanks

Answer 1

您可以使用wp_get_referer(). 在文档中阅读更多信息。

或者只是打电话给：$_SERVER['HTTP_REFERER']。

Answer 2

没有返回上一页 id 的 wordpress 函数。但是，您可以使用$_SERVER['HTTP_REFERER']. 它应该包含上一页的 ID 作为参数。结合parse_url和parse_str你应该能够获得ID：

parse_str(parse_url($_SERVER['HTTP_REFERER'], PHP_URL_QUERY), $output);
$id = $output['p'];
