Cum Adaug Un Nou Cod Pentru Adaugare Eroare (Nume Deja Ales)


Recommended Posts

Am un formular facut in php, insa vreau sa adaug, in care un vizitator care completeaza formularu, in casuta subdomeniu, un nume: abc, vreau sa dea eroare, numele este folosit .. sper ca ati inteles.

exemplul din formular, cum adaug aici:

 if (!empty($_POST['subdomeniu'])) {

            $subdomeniu = stripslashes(strip_tags($_POST['subdomeniu']));

            $_SESSION['subdomeniu'] = $subdomeniu;

        } else {

            $subdomeniu = NULL;

            $_SESSION['subdomeniu'] = '';

            $erori[] = 'Nu ati completat campul <strong>Subdomeniu</strong>.';


vreau sa mai adaug aici ca sa dea eroarea, numele ales este deja folosit, multumesc frumos

<form action="" method=post>

Subdomeniu: <input type=text name=subdomeniu><br>

<input type=submit name=submit value=Trimite>



if(isset($_POST['submit'])) {

if(isset($_POST['subdomeniu']) && empty($_POST['subdomeniu'])) { echo "Nu ai completat campul !"; }

if(isset($_POST['subdomeniu']) && !empty($_POST['subdomeniu'])) {

$_SESSION['subdomeniu'] = $_POST['subdomeniu'];

echo "Subdomeniul este: ".$_SESSION['subdomeniu'];

// alte actiuni
