News Posting Problem

[intermediate]

I am using a news posting system. I disabled html in the posts so people could not use html so they couldn't mess up the site layout. I want to make it so everytime they type a url or email address or other things in their post it automatically converts it into a link when it's displayed.

Can someone please show me how to go about doing that?

thanks 🙂

i've never used regex, but that's what you'd use, basically regex would search thru the article looking for [e-mail], then add mailto://[e-mail] next to it. g'luck

probably you should use regular expressions to replace anything like [e-mail] by a mailto link, and the same with URLs.

You can also put some kind of special tags like BB code or this vB code: i.e. [mail][e-mail][/mail]. If you decide to do this you have to process the message:

$message=preg_replace ("/\\[mail\\](.*?)\\[\\/mail\\]/ie","check_mail ('\\\\1')",$message);


function check_mail ($mail) {
        $mail=trim ($mail);
        if (preg_match ("/\\w+\\@\\w+\\.\\w{2,4}$/i",$mail)) $dev="<a href=\"mailto:".$mail."\">".$mail."</a>";
        else do anything "else";
        return $dev;
}

the first line checks if any "[mail]...[/mail]" tag have been written in the message, and the function called by it is to check if the mail is right. You canl also write and else sentence in the function just in case the mail is wrong.
Probably the patterns used in regular expressions are not the best ones as i'm just starting to learn them.
hope it helps.

what's wrong with this:

$text = preg_replace("[a-zA-Z0-9-]+@[.a-zA-Z0-9-]+.[._a-zA-Z0-9-]", "<a href=\"mailto:$1">$1</a>", $text);

im trying to get the script to replace any emails typed in $text with a mail url.

i get this error when executing the script:

"Warning: Unexpected character in input: '\' (ASCII=92) state=1 in /home/chris/public_html/six/tests/replaceurls.php on line 11

Parse error: parse error, unexpected T_LNUMBER, expecting T_VARIABLE or '$' in /home/chris/public_html/six/tests/replaceurls.php on line 11"

the script i typed is in line 11.

someone help plz!

maybe you should try just in one forum each time (and maybe with just an user name)
