Guten Abend,
ich habe nun nach etwas längerer Suche endlich ein entsprechendes und fähiges Upload-Script gefunden.
Quelle: http://www.ineedtutorials.com/articles/php-file-upload
Nun würde ich gerne noch den Dateinamen numerisch ändern lassen. Sprich "Urlaubsphoto92.jpg" (lokal) wird zu "671232.jpg" (Server). Das sollte doch mit Hilfe eines Counters o.Ä. möglich sein. Ausserdem würde ich nach erfolgreichem Upload die Url zum Bild per echo ausgeben lassen. Sollte doch auch mit Variablen möglich sein. Ich habe leider so gut wie keine Ahnung von PHP. Vielleicht kann mir jemand helfen. Danke schon mal! Gruß!
P.S.: Ich glaube, der Begriff "numerisch" passt nicht wirklich, viel mehr "durchnummeriert".
