Deze code boven zou een ok melding moeten geven als de username meer dan 4 tekens bevat.
Echter is het zo dat wat ik ook doe hij blijft aangeven dat het te kort is.
Wie kan mij in de goede richting duwen.
Met vriendelijke groet,

Dit is de output
te kort Array ( [action] => check_username [username] => testing )
Hetzelfde probleem doet zich voor als ik toch ga posten
Dit is de php code die het checked mocht js uitvallen

elseif($_POST['username'] == "" || strlen($_POST['username'] < 4) || strlen($_POST['username'] > 15 ))
{
echo '<div class="fail">Youre username must contain between 4 and 15 signs</div>';
}
{
echo '<div class="fail">Youre username must contain between 4 and 15 signs</div>';
}

Je haakjes staan verkeerd.
strlen($_POST['username'] < 4)
moet zijn
strlen($_POST['username']) < 4
En die ander idem.
Dank je voor je snelle reactie SanThe.
