Limit user to 1 post

Hello,

Thanks for the feedback!

Yes, there are multiple ways to achieve it.

1. Hide the form on the template page

You could get the posts of the currently logged user, and if there is more than one post, do not call the acfe_form() functions. Usage example:

// get current user posts
$get_user_posts = get_posts(array(
    'post_type'      => 'post',
    'posts_per_page' => -1,
    'author'         => get_current_user_id()
));

// if user have less than one post, show the form
if(count($get_user_posts) < 1){
    acfe_form();
}

2. Hide the form using a hook

You could use the same method, but within the acfe/form/load hook. Useful if you’re using the shortcode. See documentation.

3. Use a form validation error

An another solution could be to check the user posts count inside a form validation hook, and throw an error if he already has a posted something. You can do that using the acfe/form/validation action. See documentation. Usage example:

add_action('acfe/form/validation/form=my-form', 'my_form_validation', 10, 2);
function my_form_validation($form, $post_id){
    
    // get current user posts
    $get_user_posts = get_posts(array(
        'post_type'      => 'post',
        'posts_per_page' => -1,
        'author'         => get_current_user_id()
    ));
    
    // count user posts
    if(count($get_user_posts) >= 1){
        
        // add validation error
        acfe_add_validation_error('', 'You are not allowed to post more than one time');
        
    }
    
}

Hope it helps!

Have a nice day!

Regards.
