Traduci "controllare"

ciao

[lellione]

verificare se il campo viene compilato o rimane vuoto!

Io non vedo nessuna textarea

Minimale

<form method="post" action="http://localhost/sito_internet/registrazione.php" name="registrazione"
onsubmit="return (this.form.nomecampotesto1.value && this.form.nomecampotesto2.value && ... eccetera)">

Comunque trovi infinite discussioni sull'argomento "controllo form" nel forum...

ciao
