Perform custom action after post is publish using form

Hi @june01

Please see the pods_save_pod_item hook:
https://docs.pods.io/code/action-reference/pods_api_post_save_pod_item_podname/#page-header-1347

Cheers, Jory

Thanks. Can I also display custom error messages? I want to add some more logic into it but I would need to display error messages in frontend for the user to see in case of failure.
or maybe block the form when a specific condition is not met.

Hi @june01

Depends on what kind of error messages you are talking about.
All fields have a validation filter available: pods_field_validate_{$type}

Cheers, Jory

I want to check if the user has already published a post. If that’s the case then an error message should be displayed. Or the form should be blocked with some message at the top indicating that they cannot publish more than one post.

I think I can figure out how to query the database and see how many published posts the current user has, but I don’t know how to display error messages and where to put the code.

That should be done with PHP code before running the shortcode.
This can be done within your theme or in a custom plugin, depending on how/where you use it.

Also, the check would need to be done pre-saving a post, not post: pre_save_pod_item: https://docs.pods.io/code/filter-reference/pods_api_pre_save_pod_item_podname/

There is a form specific filter as well: pods_shortcode_output
https://github.com/pods-framework/pods/blob/2.8.0/includes/general.php#L1290-L1300
With this filter you can change the HTML output of the shortcode.

Cheers, Jory

thanks a lot. using the pre_save_pod_item I was able to check if the user has published posts and prevent saving in case they have using this code below:

add_filter('pods_api_pre_save_pod_item_ad_post', 'count_published_pods', 10, 2); 
    function count_published_pods($pieces, $is_new_item) { 
		
		 $id = get_current_user_id();
		if ( $id ) {
			$params = array(
				'where' => 't.post_author = "'.$id.'"',
			);
			$pods = pods( 'ad_post', $params );
			if($pods->total() == 0){
				return $pieces;
			}
			 else { 
				 //if not throw an error. 
				 wp_die( 'You shall not pass!'); 
			 } 
		}
    }

But I couldn’t figure out how to use pods_shortcode_output. My current code always displays a success message even when the pod is not saved. In the else statement, I would need something to replace it with an error message.

Hi @june01

As I mentioned, your check should be done before rendering the shortcode.

You could also try to fully overwrite the shortcode ouput if a user already has posts. That way the user cannot submit new posts anyway since the form isn’t visible.

Something like:

add_filter( 'pods_shortcode_output', 'my_pods_shortcode_output' );
function pods_shortcode_output( $output, $tags, $pod, $context ) {
    if ( 'form' === $context ) {
        // check here if your user already has posts
        if ( true ) {
            // Do not return form if the user already has posts.
            return 'Error message or something else.';
        }
    }
    return $output;
} 

hi,
the code is not working for me, what I am doing wrong?

add_filter( 'pods_shortcode_output', 'my_pods_shortcode_output' );
function my_pods_shortcode_output( $output, $tags, $pod, $context ) {
	 if ( 'form' === $context ){
		  // check here if your user already has posts
		 $id = get_current_user_id();
		if ( $id ) {
			$params = array(
				'where' => 't.post_author = "'.$id.'"',
			);
			$pods = pods( 'ad_post', $params );
			if($pods->total() == 0){
				 return $output;
			}
			 else { 
				 //if not throw an error. 
				  return 'Error message or something else.';
			 } 
		}
	 }    	
}

Hi @june01

You should always return the $output by default (last line of the function).

add_filter( 'pods_shortcode_output', 'my_pods_shortcode_output' );
function my_pods_shortcode_output( $output, $tags, $pod, $context ) {
	if ( 'form' === $context ){
		// check here if your user already has posts
		$id = get_current_user_id();
		if ( $id ) {
			$params = array(
				'where' => 't.post_author = "'.$id.'"',
			);
			$pods = pods( 'ad_post', $params );
			if( $pods->total() ){
				// User already has posts, throw error.
				return 'Error message or something else.';
			}
		}
	}
	// Normal output.
    	return $output.
}

thanks for the replay but the code does still not work. I think it’s not even been called.

Hi @june01

Where did you add the code?

I am using code snippets plugin and I’ve added it there.

Hi @june01

Sorry for my late reply.
I’m not sure if this plugin is compatible in adding filters to WordPress. I honestly doubt it. In any case such a plugin is a security right and I would recommend adding such code in your theme’s functions.php file or in a separate plugin.

Cheers, Jory

hi,
I added the code in functions.php but same problem, it does not work. Nothing happens.

Hi, I’ve changed the code to solve this issue. Instead of using the form shortcode I am creating my own one, and it’s working. When the user has a published post it displays an alert message instead of the form.

The only issue I have is on submit the page reloads and then the alert is displayed because the post is saved. But I want a success message too. How do I know if they just opened the page or have successfully submitted the form?

Also, I would like to change the button text on the form.

That’s my code

add_shortcode( 'ad_post_form', 'ad_post_form_shortcode' );

// this function generates the shortcode output
function ad_post_form_shortcode( $args ) {
	// check here if your user already has posts
	$id = get_current_user_id();
	if ( $id ) {
		$params = array('where' => 't.post_author = "'.$id.'"',);
		$pods = pods( 'ad_post', $params );
		if( $pods->total() > 0){
			// User already has posts, throw error.
			$content = '<div class="custom_alert">?? ????? ??? ???? ?? ????? ???? ?? ??? ?????.</div>';
			return $content;
		}
	}
	
	
	$mypod = pods( 'ad_post' );
	// Override the options of a specific field
	$fields = array( 'post_title' => array('label'=>'????? ???????'), 'website','ad_position_field','ad_image' );
	// Output a form with specific fields
	echo $mypod->form( $fields );
	
}
