Relationship field returning ID, how to return the correct values.

Hi guys,

Im having a little trouble returning the correct value with the relationship field.

My end result is to use the relationship field to add selected locations to a drop down in gravity forms. I can populate the drop down and get most of it working.

The issue is when i call the field inside functions.php and print the results to my page all i am is getting is the correct post ID but with get_the_title() its returning the page name of the page itself not the post i am after.

Any help much appreciated.

Been looking for a solution for past few days, with no luck.

add_filter( 'gform_pre_render_4', 'freetrial_studios' );
add_filter( 'gform_pre_validation_4', 'freetrial_studios' );
add_filter( 'gform_pre_submission_filter_4', 'freetrial_studios' );
add_filter( 'gform_admin_pre_render_4', 'freetrial_studios' );
function freetrial_studios( $form ) {

    foreach ( $form['fields'] as &$field ) {

        if ( $field->type != 'select' || strpos( $field->cssClass, 'studio-list' ) === false ) {
            continue;
        }

		$post_id = $GLOBALS['post']->ID;  
	   	$studios = get_field('field_557a974776dd2', $post_id);  
	   	
	   	if( $studios ) {
		   	
		   	$choices = array();
	   		
	   		foreach ( $studios as $studio ) {
		   		
		   		$studiotitle = get_the_title();
		   		
		   		print_r( $studio ); echo '<br>'; print_r( get_the_title() );echo '<br>';print_r( $studiotitle );
		   		
		        $choices[] = array( 'text' => $studio, 'value' => $studio );
				
				$field->choices = $choices;   
	        }
	        
	        print_r ('<br>'); ( $studio ); echo '<br>'; print_r( get_the_title() );echo '<br>';
	   		
	        $field->placeholder = 'Select a Studio';
	        $field->choices = $choices;        
        }
    }
    return $form;
}

I managed to get the correct wording to display in the drop down. Does this look like best practice for retrieving that info. But its now throwing errors in the wp-admin from this line = $studio_id = $GLOBALS[‘post’]->ID;

add_filter( 'gform_pre_render', 'freetrial_studios' );
add_filter( 'gform_pre_validation', 'freetrial_studios' );
add_filter( 'gform_pre_submission_filter', 'freetrial_studios' );
add_filter( 'gform_admin_pre_render', 'freetrial_studios' );
function freetrial_studios( $form ) {

    foreach ( $form['fields'] as &$field ) {

        if ( $field->type != 'select' || strpos( $field->cssClass, 'studio-list' ) === false ) {
            continue;
        }
		
		$studio_id = $GLOBALS['post']->ID; 
	   	$studios = get_field('field_557a974776dd2', $studio_id);
	   	
		   	if( $studios ) {
			   			 	
			   	$choices = array();
	
		   		foreach ( $studios as $studio ) {
			   		
			   		// Populate the drop down field with values	   				   		
			        $choices[] = array( 'text' => $studio->post_title, 'value' => $studio->post_title );
					$field->choices = $choices;   
		        }
		        	   		
		        $field->placeholder = 'Select a Studio';
		        $field->choices = $choices; 
	        }       
    }
    return $form;
}

Also Any idea on how i could get the value of that selected field, and retrieve a custom field that is related to that post ID eg. a custom email address field that i have set up for each studio.

Thanks

first, sorry for not answering sooner but when you answer your own post it gets removed from the awaiting reply list.

Anyway

I think you were closer on you first attempt. The problem was that you were not supplying the correct post ID for get_the_title.

If you are returning an array of IDs from your relationship field then you should use $studiotitle = get_the_title($studio);

If you’re returning post object from acf then you should use $studiotitle = get_the_title($studio->ID);

Thanks

That makes it much more clearer now. I didnt realise there was a difference between the array and post object setting.
