Limiting Tags

All Topics → → Limiting Tags

My forms are working fantastic and this plugin is brilliant! Formidable completely powers my site and I am so happy I found it! I have a question regarding front-end posts. I am running into “tag abuse” by some of my users, forcing me to have to edit some posts however I am looking for a way to limit the character or word count on the tag field . Is there a simple way to accomplish this?

Thank you!

You can do this fairly easily with a bit of custom code. you would want to add this to your theme's functions.php file or to a new plugin:

add_filter('frm_validate_field_entry', 'my_custom_validation', 10, 3);
function my_custom_validation($errors, $posted_field, $posted_value){
  if($posted_field->id == 25){ //change 25 to the ID of the field to validate
    //check the $posted_value here
    $words = explode(' ', $posted_value); //separate at each space
    $count = count($words); //count each word
    //if it doesn't match up, add an error:

    if($count > 3) //change 3 to the max number of tags
        $errors['field'. $posted_field->id] = 'Please limit your number of tags to 3 or less.';
  }
  return $errors;
}

Make sure you switch out the 25 for the id of your tags field, and change the 3 to the number of words you want users to be limited to.
