Hi all long time no see

 

I tend to keep my layouts in separate files from my main php code and call the layout from within php, most of the time the layout is called within a function also... so heres my problem

 

i have a layout page that contains the code...

headTemplate.php

<html>
<head>
<title><?php print $pagetitle; ?></title>
...it goes on from there

 

now head template gets called from index.php like so

<?php
function show_form($errors = '') {
$pagetitle= "BLAH BLAH BLAH";
require_once('templates/headTemplate.php');
}

show_form();
?>

 

but the BLAH BLAH BLAH is not displayed in the title bar of my window, am I somehow throwing this variable out of scope? what could be wrong?

 

thanks

variables in user defined functions have a local scope, so the variable you are using to set the title isnt usable by that page.

An alternative would be to do make the variables in your function global, IE:

 

<?php
function show_form($errors = '') {
  global $pagetitle= "BLAH BLAH BLAH";
   require_once('templates/headTemplate.php');
}

show_form();
?>

 

I believe that would make it so that you could use that variable in your other page.

tang, yes $pagetitle should be passed to headTemplate but it is not.

 

mikesta, good suggestion but it didnt work, you cant declare a global variable and define it in the same line so I broke it apart and that didnjt work, then i defined the var outside the function, then made it global. then I put the global declaration inside of headTemplate at the top and that didnt work either

 

any other suggestions from the crowd, Im not new at this php thing but this is making me nuts.

Has the added template got the variable.

 

  $pagetitle= "BLAH BLAH BLAH"; <<<<<<<<<<<<<

 

 

  require_once('templates/headTemplate.php'); in this page?

 

make sure the directory/to the file is correct!
