Problemi inserimento script

[nala84]

Salve, io dovrei aggiungere in questa pagina uno script sempre in php per mandare l'e-mail. Ho provato con A71mail ma non ci sono riuscita. Tipo anche a fare il collegamento. La pagina è questa:

La mia domanda : dove devo aggiungere lo script? e soprattutto quale? Grazie mille.

Scusa, ma tu devi semplicemente mandare una mail?
Allora ti conviene semplicemente usare mail():
http://www.php.net/manual/en/function.mail.php

[nala84]

No, volevo aggi il programma a71mail.Proprio ora ci sono riuscita, perè mi da errore la pagina di a71mail.php. Questo è l'errore:
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\Moodle\server\moodle\course\a71mail.php:1) in C:\Moodle\server\moodle\course\a71mail.php on line 7

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\Moodle\server\moodle\course\a71mail.php:1) in C:\Moodle\server\moodle\course\a71mail.php on line 7

Da cosa può essere causato? Cosa ho sbagliato?

[artorius]

leva l'html dalla pagina e lascia solo il PHP

[nala84]

Scusa da quale pagina?
La pagina dove da errore è questa:

A me sembra tutta in php. Dov'è l'errore? Non capisco, eppure l'ho presa già pronta da questo sito... Qualcuno mi può aiutare?

[artorius]

dunque, se leggi il primo codice che hai postato, noterai che la prima riga è


ed è fuori da <? ?> quella parte è HTML che vieni inviato prima del PHP eseguito che, in qualche punto, riscrive gli header della pagina.
Quando si cambiano gli header della risposta, non si può, in nessun modo, stampare del HTML prima. E' questo che indica l'errore di prima.

[nala84]

Quindi tu dici ke cancellando il primo rigo

mi dovrebbe sparire l'errore? O devo cancellare anche altro? Ti ringrazio.

[nala84]

Ho provato a togliere il

a inizio pagina e </p> a fine pagina ma non è cambiato niente

[artorius]

hai tolto tutto quello che c'è fuori i tag php (fuori <? e ?>)?

[nala84]

Si, ho tolto tutto ma non è cambiato niente. Ma non è che è un problema del programma A71mail? Rispondetemi al più presto, vi prego
