placeholder change data

Question

I have a form which gets user's telephone and stores it in an database. Then I am fetching data from the database and place it on placeholder like this.

Telephone<input name="telephone" type="text" size="25" placeholder="<?php echo $user_data_profile['telephone']; ?>"/>

everything is fine. I want to make the placeholder's data to appear as an editable text, so that the user will have the option to change his telephone number easy. Any suggestions?

Answer 1

I would suggest:

Telephone
<input name="telephone" type="text" size="25"
       placeholder="xxx-xxx-xxxx" value="<?=$user_data_profile['telephone']?>"/>

Using whatever phone number format that is relative to your area.
