Ich habe zwei Dateien connect.php und login.php. Das Anmeldeskript gibt eine Benutzer-ID oder ein Passwort zurück, aber ich weiß, dass sie korrekt sind.PHP Fehler? in Passwort oder Benutzername
Die DB-Verbindung scheint in Ordnung zu sein und ich kann keinen spezifischen Fehler im PHP-Code in login.php sehen.
Kann jemand den Fehler erkennen oder in die richtige Richtung zeigen?

Dies ist die DB-Verbindung, aber es sieht gut aus.
<?php
$hostname="localhost";
$username="xxx";
$password="xxxx";
$database="xxx";
$con=mysql_connect($hostname,$username,$password);
if(! $con)
{
die('Connection Failed'.mysql_error());
}
mysql_select_db($database,$con);
?>
Warum verwenden Sie das veraltet Bibliothek 'mysql_'? Versuchen PDO/MySqli statt –
Ich sehe kein 'Name' Attribut in keinem der Felder - Das, was den Wert aus dem Feld in der von' $ _REQUEST', '$ _POST',' $ _GET' verbinden –
&& ? Schreiben Sie das Wort Und ... – Proxytype
