clearing chatbox & adding BBCode

[deathadder]

hi, i followed phpacademys login and register system from part one to part twenty two, after this i created a nice web design

 

and added a php chatbox now what i want to know is

 

i have a function called protect_page() that redirects guests to a error message and i have a

 

has_access() function which checks the users rank, this is all good but if i want multiple ranks eg 1, 2, 3, but 4 not to access it how would i do this i am currently doing this

 

if (has_access($session_user_id, 4) === true) {
       echo 'you do not have the rights to view this page';
} else {
      echo 'You have the rights';
}

 

i would like something like this

 

if (has_access($session_user_id < 3) === true) {

}

 

but this just wont work.

 

another issue i have i have a function called BBCode used in an echo as

 

$text = '
[center]center text[/center]
';
echo BBCode($text);

 

it converts the BBCode to html i would like to use it in this file, which will work with my chatbox

 

<?
include 'core/init.php';


if(isset($user_data['first_name'])){
$text = $_POST['text'];

$fp = fopen("log.php", 'a');

fwrite($fp, '('.date('g:i A').') <b><a href="'. $user_data['username'] .'" target="_blank">'.$username.'</a></b>: '.stripslashes(htmlspecialchars($text)).'<br>
');
fclose($fp);
}
?>

 

the BBCode function is

function BBCode ($string) {
$search = array(
     '#\[center\](.*?)\[/center\]#si',
     '#\[list\](.*?)\[/list\]#si',
     '#\[li\](.*?)\[/li\]#si',
     '#\[b\](.*?)\[/b\]#si',
     '#\[br\](.*?)\[/br\]#si',
     '#\[i\](.*?)\[/i\]#si',
     '#\[u\](.*?)\[/u\]#si',
     '#\[img\](.*?)\[/img\]#si',
     '#\[url=http://(.*?)\](.*?)\[/url\]#si',
     '#\[size=(.*?)\](.*?)\[/size\]#si',
     '#\[font=(.*?)\](.*?)\[/font\]#si',
     '#\[color=(.*?)\](.*?)\[/color\]#si',
     '#\[code\](.*?)\[/code\]#si'
);
$replace = array(
     '<center>\\1</center>',
     '<ol>\\1</ol>',
     '<li>\\1</li>',
     '<b>\\1</b>',
     '<br>\\1</br>',
     '<i>\\1</i>',
     '<u>\\1</u>',
     '<img src="\\1">',
     '<a href="\\1">\\2</a>',
     '<font size="\\1">\\2</font>',
     '<font family="\\1">\\2</font>',
     '<font color="\\1">\\2</font>',
     '<code>\\1</code>'
);
return preg_replace($search, $replace, $string);
}

 

thanks

 

 

one last thing i need, the chatbox i have sends the entered data with the php code i sent above, to log.php, i was wonderign if there was a faster way of clearing this chatbox then going into the file and removing all the content form it?

would it be possible to add a word to reset it like [reset] with a similar method to the bbcode or something along those lines

 

thanks

Passing the user level to the has_access function should return a true or false, that is what you should check.  You cannot pass operators in the function arguments like that.  Being that we don't have access to the has_access() function, we cannot point you in the right direction.  However, for you second problem.

 

Replace your BBCode function with this snippet, and you can type [reset] and it will clear the file for you (it writes [reset] at the top of the file).

function resetLog() {
$logFilename = 'log.txt'; //filename.
file_put_contents($logFilename,'[reset]'); //open the file, overwrite the contents with the string [reset], close the file.
return true; //return true.
}

function BBCode ($string) {
//looking for the reset code
if(strpos($string,'[reset]') !== false) { //if string is found.
	resetLog(); //call the reset function.
	$string = str_replace('[reset]','',$string); //delete the string [reset] from the input.
}
$search = array(
     '#\[center\](.*?)\[/center\]#si',
     '#\[list\](.*?)\[/list\]#si',
     '#\[li\](.*?)\[/li\]#si',
     '#\[b\](.*?)\[/b\]#si',
     '#\[br\](.*?)\[/br\]#si',
     '#\[i\](.*?)\[/i\]#si',
     '#\[u\](.*?)\[/u\]#si',
     '#\[img\](.*?)\[/img\]#si',
     '#\[url=http://(.*?)\](.*?)\[/url\]#si',
     '#\[size=(.*?)\](.*?)\[/size\]#si',
     '#\[font=(.*?)\](.*?)\[/font\]#si',
     '#\[color=(.*?)\](.*?)\[/color\]#si',
     '#\[code\](.*?)\[/code\]#si'
);
$replace = array(
     '<center>\\1</center>',
     '<ol>\\1</ol>',
     '<li>\\1</li>',
     '<b>\\1</b>',
     '<br>\\1</br>',
     '<i>\\1</i>',
     '<u>\\1</u>',
     '<img src="\\1">',
     '<a href="\\1">\\2</a>',
     '<font size="\\1">\\2</font>',
     '<font family="\\1">\\2</font>',
     '<font color="\\1">\\2</font>',
     '<code>\\1</code>'
);
return preg_replace($search, $replace, $string);
}

thanks the reset workes but the bbcode doesn't here is my has_access function

 

function has_access($user_id, $type) {
$user_id	= (int)$user_id;
$type 		= (int)$type;

return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `user_id` = $user_id AND `type` = $type"), 0) == 1) ? true : false;
}

 

the reset works fine but the actual BBCode function i have isn't working

 

here is my post.php file

 

include 'core/init.php';


if(isset($user_data['first_name'])){
$text = $_POST['text'];

$fp = fopen("log.php", 'a');
$input = '('.date('g:i A').') <b><a href="'. $user_data['username'] .'" target="_blank">'.$username.'</a></b>: '.$text.'<br>';


fwrite($fp, ' ' . BBCode($input) . '
');
fclose($fp);
}

 

i dont understand it, [reset] is in the BBCode bit and yet it works when the bbcode doesn't also it would be helpful if you could find a useful method for making [reset] only work for user access level 1
