extract variables from content

content variables extract

[David_M]

I'm trying to hack the following code.
What it does is extract the first digit (1) from [hidepost=1]content[/hidepost]
What i want to do is use code like [hidepost=Level1]
so I need to extract everything between the "[hidepost=" and "]"

Any ideas? Thanks!

global $current_user, $user_ID, $hidepost_content_text,$user_level, $m_id, $hidepost_role_text;
$m_id++;
preg_match_all('#\[hidepost(.*?)\](.*?)\[/hidepost\]#sie', $content, $matches);//Find the hidepost tag
$level_tag = $matches[1][$m_id];

$max_level = 0;
if ($level_tag[0] == '=') {
$max_level = $level_tag[1]; //Get the level require
//Get the level require
}

why don't you use replace?

$hidepost = eregi_replace("hidepost=", "hidepost=level", $hidepost);

Hi Dull,

I'm not trying to replace the contents, I'm trying to extract the contents from the string. But maybe I'm misunderstanding the operator?

Try something like this:

$pattern = '/\[hidepost=([^\]]+)\]/i';
if(preg_match($pattern, $string, $match)) {
echo '<pre>'; print_r($match); echo '<pre>';
} else {
echo 'No match!';
}
