First name validation using html 5 pattern

Question

I have this code

 echo '<input type="text" maxlength="32" name="first_name" pattern="[A-Za-z]" value="'.$_SESSION['user_first_name'].'" required>';

Even if I put something correct it says 'PLease match the requested format'

The data is 'testme' which is correct but it's not passing the validation.

Answer 1

You need to specify how long the pattern should be. pattern="[A-Za-z]{1,32}"

echo '<input type="text" maxlength="32" name="first_name" pattern="[A-Za-z]{1,32}" value="'.$_SESSION['user_first_name'].'" required>';

Answer 2

pattern="[A-Za-z ]{1,32}" <- Use space in the first name pattern.
