BBCode

[lostprophetpunk]

I am making a simple posting system.

 

I have the following code to deal with the bbcode...

function bbcode_format ($posted) {
        $posted = htmlentities($posted);

        $simple_search = array(
                                '/\[b\](.*?)\[\/b\]/is',                               
                                '/\[i\](.*?)\[\/i\]/is',                               
                                '/\[u\](.*?)\[\/u\]/is'
                                );

        $simple_replace = array(
                                '<b>$1</b>',
                                '<i>$1</i>',
                                '<u>$1</u>'
                                );

        // Do simple BBCode's
        $posted = preg_replace ($simple_search, $simple_replace, $posted);

        return $_POST['entry'];
}

The data of '$posted' is then inserted into the database. But when I view the post on a different page, it hasn't worked.

 

Am I doing something wrong?

<?php

function bbcode_format($posted) {
        $posted = htmlentities($posted);

        $simple_search = array(
                                '/\[b\](.*?)\[\/b\]/is',                               
                                '/\[i\](.*?)\[\/i\]/is',                               
                                '/\[u\](.*?)\[\/u\]/is'
                                );

        $simple_replace = array(
                                '<b>$1</b>',
                                '<i>$1</i>',
                                '<u>$1</u>'
                                );

        // Do simple BBCode's
        $posted = preg_replace ($simple_search, $simple_replace, $posted);

        return $posted;
}

echo bbcode_format("[b][u][i]hello[/b][/u][/i]");
?>

If htmlentities() translates square brackets to their entity equivalent, the function won't work.

[marcus]

Lol, there is no equivalence for the bracket.

Well, had to check now. There is indeed HTML entity equivalents for the square brackets ([ and ]), but htmlentities() doesn't translate them (at least not in PHP 5.2.2). So the OP is fine.
