This may be a noob question, but I've searched this forum and nothing fit.

My include file (snippet.inc.php):

Code:

<?php
include_once $modx->config['base_path'].'template.php';

$a='a variable';
template(); // I'm trying to display the result
?>

My template function (template.php):

Code:

<?php
function template(){ // This was meant to be a display function
  global $a;
  echo 'I\'m calling '.$a;
}
?>

If I run this code outside of modx, it works.

I'm calling a variable // test outside modx
I'm calling // result in modx

How to make it run inside modx?

It's a question of variable scoping (remember that snippets are eval'ed within MODx Evo), this works:

Code:

<?php
global $a;

function template(){ // This was meant to be a display function
  global $a;
  return 'I\'m calling '.$a;
}

$a = 'a variable';
return template($a);
?>

Although, the more preferable way (to eliminate globals) would be:

Code:

<?php
function template($a){ // This was meant to be a display function
  return 'I\'m calling '.$a;
}

$a = 'a variable';
return template($a);
?>

hummm...
the global's needed because we're talking about 2 different files, no?

Anyway,

Code:

<?php
$a = 'a variable';
return template($a);

not run

Code:

<?php
$a = 'a variable';
echo template($a);

run

How should I use return?
Meanwhile, this one work:

Code:

file: snippet.inc.php
<?php
global $a; // different with a standalone php file
$a = 'a variable';
return template();
?>

file: template.php
<?php
function template(){ // This was meant to be a display function
  global $a;
  echo 'I\'m calling '.$a;
}

Or

Code:

file: snippet.inc.php
<?php
global $a; // different with a standalone php file
$a = 'a variable';
echo template(); // I think this one, since the "echo" doesn't immediately end execution the rest of the codes.
?>

file: template.php
<?php
function template(){ // This was meant to be a display function
  global $a;
  return 'I\'m calling '.$a;
}
