How to redirect a user to a different page based on the number of form entries in WordPress

Question

I am trying to redirect a user based on whether or not they have an entry in a form. I am using formidable plugin. I set the variable $count to be a global variable but for some reason I can't get it to work outside of the function check_entry_countt . When I print it outside the variable, it returns a NULL value.

To avoid this, I decided to use the my_logged_in_redirect() function inside the check_entry_countt function but then the redirect function also stops working.

To get this code to work properly, I have two ways, whichever works better.

1. To use the redirect function my_logged_in_redirect() inside the check_entry_countt function so that it accesses the $count variable.
2. To use the redirect function my_logged_in_redirect() outside the check_entry_countt function but then get the function to access the $count variable as a global variable (which is not working for me). The code.

add_action( 'wp_enqueue_scripts', 'child_enqueue_styles', 15 );
nocache_headers();


add_action('frm_display_form_action', 'check_entry_countt', 8, 3);
function check_entry_countt($params, $fields, $form){
  global $user_ID;
  $current_user = wp_get_current_user();
  remove_filter('frm_continue_to_new', '__return_false', 50);
  if( $form->id == 4 && !is_admin() && user_can( $current_user, "booknetic_staff" ) ){ //replace 4 or 5 with the ID of your form
    global $count;
    $count = FrmEntry::getRecordCount("form_id=". $form->id ." AND user_id=".$user_ID); 
    if($count >= 1){ //change 1 to your entry limit
      echo 'You have already submitted your data. Please visit your profile/account if you want to update';
      add_filter('frm_continue_to_new', '__return_false', 50);
    } elseif ($count == 0) {
      //i need to run the redirect function here
    }
  }

}

The redirect function

  function my_logged_in_redirect() {
    
    if ( (is_front_page() || is_page('profile') || is_page('account'))  && is_user_logged_in()) 
    {
      
        wp_redirect( '/first-time-application-temp/'); 
        die;
    }
}
add_action( 'template_redirect', 'my_logged_in_redirect' );

The goal: So that elseif ($count == 0) { //i can run the redirect function} as shown in the code.

If I was able to fetch the value of the global variable $count, inside my redirect function, I'd simply add the variable inside the if statement as so:

if ( ($count == 0 && is_front_page() || is_page('profile') || is_page('account')) && is_user_logged_in()){...} Whichever options works, either fetching the global variable outside check_entry_countt function or making my redirect function my_logged_in_redirect() work inside the check_entry_countt function, I'm fine. Currently, the global variable $count is being identified as undefined outside.

Clarification - When I say the redirect function also stops working I mean this:

The redirect function is working outside the check_entry_countt function . No redirection happens when I insert the redirect function inside this if statement elseif ($count == 0) { // the redirect function stops redirecting when added here }

Answer 1

Normally from the my_logged_in_redirect() function; Use must work properly Consider my example:

The first example:

add_action('frm_display_form_action', 'check_entry_countt', 8, 3);
function check_entry_countt($params, $fields, $form)
{
    global $user_ID;
    $current_user = wp_get_current_user();
    remove_filter('frm_continue_to_new', '__return_false', 50);
    if ($form->id == 4 && !is_admin() && user_can($current_user, "booknetic_staff")) { //replace 4 or 5 with the ID of your form
        $count = FrmEntry::getRecordCount("form_id=" . $form->id . " AND user_id=" . $user_ID);
        if ($count >= 1) { //change 1 to your entry limit
            echo 'You have already submitted your data. Please visit your profile/account if you want to update';
            add_filter('frm_continue_to_new', '__return_false', 50);
        } elseif ($count == 0) {

            my_logged_in_redirect();
            
        }
    }

}

The redirect function

function my_logged_in_redirect() {
    
    if ( (is_front_page() || is_page('profile') || is_page('account'))  && is_user_logged_in()) 
    {
      
        wp_redirect( '/first-time-application-temp/'); 
        die;
    }
}

Remove this hook :

add_action( 'template_redirect', 'my_logged_in_redirect' );

The second example If this does not work, set the value with the parameter :

add_action('frm_display_form_action', 'check_entry_countt', 8, 3);
function check_entry_countt($params, $fields, $form)
{
    global $user_ID;
    $current_user = wp_get_current_user();
    remove_filter('frm_continue_to_new', '__return_false', 50);
    if ($form->id == 4 && !is_admin() && user_can($current_user, "booknetic_staff")) { //replace 4 or 5 with the ID of your form
        $count = FrmEntry::getRecordCount("form_id=" . $form->id . " AND user_id=" . $user_ID);
        if ($count >= 1) { //change 1 to your entry limit
            echo 'You have already submitted your data. Please visit your profile/account if you want to update';
            add_filter('frm_continue_to_new', '__return_false', 50);
        }
        my_logged_in_redirect($count);
    }

}



function my_logged_in_redirect($count)
{
    if (!empty($count) && $count == 0 && ((is_front_page() || is_page('profile') || is_page('account')) && is_user_logged_in())) {
        wp_redirect('/first-time-application-temp/');
        die;
    }

}

add_action('template_redirect', 'my_logged_in_redirect');

For the second example, because the condition is inside the function, we do not need to check here
