Help with Classes

[LejeuneBay]

I have 2 classes, a template class and a bumper class (the bumper class redirects a user away from a page which is useless to the user but vital to internal server functions to add, edit, or delete from MySQL). Basically what problem I'm having is simplifying my programing code from 7 lines to 1 line.

 

The major problem resides with trying to call "globals" and a list of given variables to replace on a template.

 

For instance, when I put down

 

(Index.php)

$VARS = "\$SITE_TITLE, \$SITE_DESCRIPTION";

template("templates/default/index.tpl"…

 

The website appears just fine with the {SITE_TITLE} and {SITE_DESCRIPTION} replaced on the template.

 

But when I try to implement classes it doesn't replace any of the {VARIABLES} that are listed. Here is the code:

 

class template{


function display($file, $vars, $x) {

	if($x == 1 || $x == 2){

		$line	=	@implode(file($file),"");

	}else{

		$line	=	file_get_contents($file);
	}
	eval("global $vars;");
	$vars = str_replace(", ","",$vars);
	$vars_list = explode("\$",$vars);
	for($i =0; $i <= sizeof($vars_list); $i++) {    
		$line = str_replace("{".$vars_list[$i]."}",$$vars_list[$i],$line);
	}
	if($x == 1){
		print $line;
	}elseif($x == 2 || $x == 3){
		return $line;
	}
}

}

class bumper extends template{

var $bumperTemplate;
//var $vars;

// Constructor
function bumper($bumperTemplate){

	/*
	 * Bumper Logic Here
	 * 
	 */
	$this->bumperTemplate 	= $bumperTemplate;
	//$this->vars				= $vars;

}

function redirect($url, $message, $delay, $classId){

	$PHP_SELF		=		basename($_SERVER['PHP_SELF']);

	$MESSAGE 		=		"<span id=\"".$classId."\">".$message."</span>
							<br><br>Redirecting...<br>
							If the page doesn't redirect automatically <a href=\"".$url."\">Click here</a>.";

	$LOCATION 		=		$url;
	$DURATION 		= 		$delay;
	$vars = "\$MESSAGE, \$LOCATION, \$DURATION, \$PHP_SELF";
	parent::display($this->bumperTemplate,$vars,1);

}

}

$template = new template();
$bumper = new bumper();

$bumper->redirect("index.php","You have successfully logged into your account.",3,"BumperCorrect");

 

 

The code should be self explanatory. Basically that "display" function under the template class is not getting the following variable values: $PHP_SELF, $MESSAGE, $LOCATION, $DURATION which are listed correct for the display function in the $vars variable.

 

The display function outputs the file, and erases all the {VAR_NAME_HERE} type variables located on the template.

 

Does any one have any suggestions? Or need me to explain it in a different way?

Explain it a different way please. I know how to use classes but I don't quite understand the problem.

This may or may not be the issue.  But it would certainly make it easier to follow what you're doing.  Try passing your list of variables as an array:

 

$vars['MESSAGE'] = "This is my message";

$vars['LOCATION']= $URL;

$vars['DURATION']=$duration;

$vars['PHP_SELF']=$php_self;

 

Then you don't have to worry about trying to explode the string out into an array.
