Limit post object to author inside user-edit.php (backend user profile)

Hi community,

in a frontend form I limit the output of a post object to the author like this:

/**  Reduce ACF Post Object Select of Featured Product to Current User */

function my_post_object_query( $args, $field, $post ) {

// modify the order

$current_user = wp_get_current_user();
$user_id = $current_user->ID;

$args['author']=$user_id;
$args['authors']=$user_id;

$args['post_type']='product';
return $args;

}

// filter for every field
add_filter('acf/fields/post_object/query/name=featured_product', 'my_post_object_query', 10, 3);

For the administrator I want to limit the same post object in the profile page of the author (user-edit.php) by not getting the current user ID but the ID of the user profile the admin is looking at like this:

global $profileuser;
$user_id = $profileuser->ID;

I can retrieve the ID but I cannot get it to work within the following post object function:

/**  Reduce ACF Post Object Select of Featured Product to Author */

function my_post_object_query( $args, $field, $post ) {

// modify the order

global $profileuser;
$user_id = $profileuser->ID;

$args['author']=$user_id;
$args['authors']=$user_id;

$args['post_type']='product';
return $args;

}

// filter for every field
add_filter('acf/fields/post_object/query/name=featured_product', 'my_post_object_query', 10, 3);

What works is if I ask for it statically like this:

....
$user_id = 2;
$args['author']=$user_id;
....

Do you have any suggestions how I could retrieve the User-ID within the function?

Any ideas would be helpful.

The problem is that the values are loaded using AJAX and during the AJAX request $profileuser probably does not contain any value.

The 3rd argument that’s passed to your function should have the use ID, but I don’t really know what’s in the argument.

you can find this out. Turn on error logging in WP by adding this to wp-config.php

define('WP_DEBUG', true );
define('WP_DEBUG_DISPLAY', true);
define('WP_DEBUG_LOG', true);

then in your filter do this

ob_start();
print_r($post);
error_log(ob_get_clean());  

Go to your user profile page, then you can look in the error log ‘/wp-contnet/error.log’ to see what get written to the file.

Hi John,

thank you for your help. I decided I ask on wpquestions.com since it was a rather complex thing and Reigel Garllade came up with a good solution.

Source: http://www.wpquestions.com/question/showChrono/id/15258

I’ll share it here, in case anybody will ever run into the same issue. For me the issue is solved, but I am curious if you have objections to the following code.

The following code goes into the functions.php

add_action('acf/input/admin_footer','admin_footer');

function admin_footer(){

	?>

	<script>

	/* <![CDATA[ */

	acf.add_filter('select2_args',function( args ) {

			if ( typeof args.ajax.data == 'function' ) {

				var old_data_func = args.ajax.data; // We'll keep this for maximum compatibility, and extend it.

				args.ajax.data = function(term, page) {

					var default_response = old_data_func( term, page ); // Call the old, default function.

					// Add the user_id to the ajax function.

					default_response.user_id = function () {return <?php echo isset($_GET['user_id'])?$_GET['user_id']:''; ?>;};

					// Return the default args with our user_id function.

					return default_response;

				}

			}

			return args;

		}

	);

	/* ]]> */

	</script>

	<?php

}

and then:

add_filter('acf/fields/post_object/query/name=featured_product', 'my_post_object_query', 10, 3);

function my_post_object_query( $args, $field, $post ) {

	// modify the order

	

	if( isset($_POST['user_id']) && is_numeric($_POST['user_id'])) {

		$user_id = $_POST['user_id'];

	} else {

		$current_user = wp_get_current_user();

		$user_id = $current_user->ID;

	}

	

	$args['author']=$user_id;

	$args['authors']=$user_id;

	$args['post_type']='product';

	return $args;

}

hello Laika,

I also found out that you can do something like this that does the same thing…

add_action('acf/input/admin_footer','admin_footer');

function admin_footer(){

	?>
	<script>
	acf.add_filter(
		'prepare_for_ajax',
		function(a) {
			if (a.action === 'acf/fields/post_object/query') {
				a.user_id = <?php echo isset($_GET['user_id'])?$_GET['user_id']:''; ?>;
			}
			return a;
		}
	);
	</script>
	<?php
}

Thank you Reigel. That looks really economic, I will try it.

My deepest respect!
