Variable = directory

I have two variables that are directories on my site:

$var1 = 'assets/images/imagefolder1';
$var2 = 'assets/images/imagefolder2';

These variables are in an include file. When I run the page, I get an error. What is the right way to write out the folder path. Do I need to use base_path somehow? Does it go outside the single quotes, or do I use

$modx->config['base_path']

in some way?

Thanks in advance for your help!

This really depends on how you are planning to use the variables. If you are going to work with files in those directories, MODX_BASE_PATH or $modx->config[’base_path’] with get you the full directory path to the folder on the server, i.e. $modx->config[’base_path’] . ’assets/images/foo/’. However, if you are going to use this in a URL, you’ll want to use $modx->config[’base_url’] (or $modx->config[’site_url’] if you want to include the complete URL including protocol, hostname, and base_url).

Yes, I’ll be using the files in those folders. So would the proper syntax be:

$var1 = $modx->config[’base_path’].’assets/images/imagefolder1’;

Just wanted to see if I had every jot and tittle in the right place. Thanks so much for your help.

If you’re intent is to include a list of files, I use a handy little piece of code that looks like this:

<?php
$files = array('assets/snippets/blah/file1.php', 'assets/snippets/other/file2.php');
foreach ($files as $file) {
	$path = $modx->config['base_path'].$file;
	if (file_exists($path)) {
		include($path);
	} else {
		die('file not found');
	}
}

You’ll want to improve the error handling of course, probably by using [tt]$modx->logEvent()[/tt]. This is really for lists of files who’s count is unknown though, so it’s really up to you to decide is this an optimal solution.

Enjoy!
