Functions and external variables

[Chris_Evans]

Hi there,
I have a function which contains two variables $title and $body both of which are returned not echoed.

That part is simple, now the next part is the problem. I found that since it doesn't send the variables out from the function to the area that it was called from (unless you use echoes) you actually have to name your call through a variable:

new ClassName;
$page = function($something);

So I did that and it all worked fine, except when I do the following:

echo $page['title'];
echo $page['body'];

When I do that, I get the first letter of the body variable from page.

So instead of:

Hi there

I get:

H

Which obviously is a problem, any ideas?

Thanks,

Chris

the variables that you return, are they in an array?!
like:

//test.inc.php

<?  

class test 
 {  	
function returnit($foo)  	
{  		
$test["first"]=$foo+1;  		
$test["second"]=$foo-1;  		
return $test;  	
}  

}  

?>

//index.php

<?php  

include('./test.inc.php');  

$testp=new test;  

$arr=$testp->returnit(2);  

echo $arr["first"]."<br>";  

echo $arr["second"]."<br>";  

?>

Lol - I'd never thought of that, no they're not in an array:

index.php (calls the function):

<?php
// Include template file
include("style/pattemplate.php");

// Include the page files
include("includes/class.php");

// Process the news script
$tmprocess = new TopMenu;
$topmenu = $tmprocess->retrieve_topmenu("menua");
$nprocess = new News;
$body = $nprocess->retrieve_news("news");

// Initialize the template file and create the necessary object
$tmpl = new patTemplate();

// Set which directory contains the template file
$tmpl->setBasedir("style");

// Set the template file to be read
$tmpl->readTemplatesFromFile("template.html");

// Add the variables to the template
$tmpl->addVar("fateam.com","pagetitle","News");
$tmpl->addVar("fateam.com","topmenu",$topmenu);
$tmpl->addVar("fateam.com","title","News @ fateam.com <<-");
$tmpl->addVar("fateam.com","body",$body);
$tmpl->addVar("fateam.com","copyright","&copy; fateam.com 2003 - <a href=\"http://www.fateam.com/legal.php\">Legal Info</a> | <a href=\"http://www.fateam.com/privacy.php\">Privacy Policy</a>");

// Parse and display the template
$tmpl->displayParsedTemplate("fateam.com");

?>

class.php (contains the function called):

<?
class Section
	{
		function call_dbfunction()
		{
			$this->dbfunction("localhost","root","");
		}

	function dbfunction($dbserv,$dbuser,$dbpass,$dbname)
	{
		$this->dbserv = $dbserv;
		$this->dbuser = $dbuser;
		$this->dbpass = $dbpass;
	}

	function dbquery($query)
	{
		$connection = mysql_connect($this->dbserv,$this->dbuser,$this->dbpass)
			or die(mysql_error());
		$ret = mysql_db_query("fateam",$query,$connection)
			or die(mysql_error());
		return $ret;
	}

	function retrieve_section($id)
	{
		if($id == "none")
			{
				$body = "No ID was provided for the page that you requested. Please try refreshing this page, if you continue to get this message please send an email to: <a href=\"mailto:[e-mail]\">[e-mail]</a>";
				return $body;
			}
		else
			{
				$query = "SELECT title,body FROM sections WHERE id='$id'";
				$result = $this->dbquery($query);
				$rowcount = mysql_num_rows($result);
				if($rowcount > 0)
					{
						$body = "";
						While($array = mysql_fetch_array($result))
							{
								$body .= $array['body'];
								return $body;
							}
					}
				else
					{
						$body = "";
						$body .= "Error! There was a problem finding the page you requested. Please refresh the page, if you continue to recieve this error then you should contact <a href=\"mailto:[e-mail]\">[e-mail]</a></td></tr>";
						return $body;
						$title = "Help";
						return $title;
					}
			}
	}
}
?>

Thanks in advance,

...when you make a return call...you end the execution of the given function...

so you cant return two variables, (one after another) as in your else statement...
put them in an array and return the array....if i ain't helping just ignore this post 🙂
