Hey, guys, I have a question

How can i make the phone number required, I know that the phone number is in the cityArea field, checking the item_post.php i just have

<div class="row">
            <label for="phone"><?php _e('Mobile Phone', 'zara'); ?><span class="req">*</span></label>
            <?php ItemForm::city_area_text($user_info) ; ?>
          </div>
I try something like the contactemail required code

contactEmail: {
              required: true,
              email: true
          },
But is not working, where i can see the <input name="cityarea" or something similar. i just want to put the code for htmlt5 required>
Thank you for your time.

HTML5 validation will not work as there is separate script that will block it.
Duplicate code for some existing field in item-post.php, you just need to rewrite name of input.
