j'ai une petite requète avec mon script livre d'or

C'est un pote que je ne vois plus qui me l'avais filé.
et quand on écrit un message sur 2 lignes, il remet tout sur une seule ligne.
J'aimerais savoir qi quelqu'un saurait comment le modifier pour que un saut a la ligne se transforme en <br>

Arf bon j'ai pas la motivation de m'attaquer à ton code le principe est d'utiliser la fonction nl2br()

Moi par exemple lorsque j'ai un message je fais deux petite chose qu'on pourrait penser inutiles mais bon ça sert en fait :mouais:

Soit la fonction :

function securehtml($content)
{
$content = ereg_replace("<","&lt;",$content);
$content = ereg_replace(">","&gt;",$content);
$content = ereg_replace("&lt;br&gt;","<br />",$content);
$content = ereg_replace("&lt;br /&gt;","<br />",$content);
return $content;
}

qui évite les codes html dans les messages

et derrière


$message= nl2br(securehtml($message));

qui transforme tes \n en <br /> et supprime tout code autre ne html (pour l'html t'es pas obligé mais c'est plus propre)

Bon il est tard mais je me suis motivé poiur regarder :

3. post the messages in the output file (the chat)

I added these three lines in order to avoid buggy html code and slashes */
$msg = str_replace ("\n"," ", $message);
$msg = str_replace ("<", " ", $msg);
$msg = str_replace (">", " ", $msg);
$msg = stripslashes ($msg);

Ici à la place tu mets
$msg = str_replace ("\n","<br />", $message);
$msg = str_replace ("<", "[FONT=Garamond,mon]&lt;", $msg);
$msg = str_replace (">", "[/FONT]&gt;", $msg);
$msg = stripslashes ($msg);

ok thanks

Il me semble que ça serait mieux d'utiliser une fonction inclue dans PHP pour traduire certains caractères utilisés en HTML. Comme par exemple, la fonction htmlentities().
