Bob's Guides

The site_url is a full URL (e.g. https://bobsguides.com). The base_url is missing the URL prefix (e.g. /bobsguides.com).

Your template should always include a base href statement using the site_url:

MODX Evolution: <base href="[(site_url)]" />
MODX Revolution: <base href="[[++site_url]]" />

Links in a MODX site should always be expressed with the link tag:

MODX Evolution [~##~]
MODX Revolution [[~##]]
(where ## is the document ID of the document being linked to. Examples:

MODX Evolution: <a href="[~12~]">Link to document 12</a>
MODX Revolution: <a href="[[~12]]">Link to document 12</a>

If you would like a fully qualified link for SEO purposes, you can use this form instead:

MODX Evolution: <a href="[(site_url)][~12~]">Link to document 12</a>
MODX Revolution: <a href = "[[++site_url]][[~12]]">Link to document 12</a>

XAMPP has mod_rewrite off by default. Uncomment the following line in xampp/apache/conf/httpd.conf:

LoadModule rewrite_module modules/mod_rewrite.so

MODX Evolution: $docid = $e->params['id'];
MODX Revolution: $docid = $modx->resource->get('id');

It depends on the event. Susan Ottwell has a good list here. They are available as simple variables. Another list can be found here.

This almost always means that you have a circular reference on your site. A page forwards users to another page that forwards users back to the first page, ad infinitum. The most common cause is having an unpublished or missing error or unauthorized page. User's who try to access a non-existent URL are forwarded to the error page. If the error page isn't published, it too doesn't exist and they're forwarded again to the same page over and over until the memory runs out. Check the error_page and unauthorized_page system settings and make sure the pages referred to there are published and not protected by a permission setting.

Another possibility is a snippet such as Ditto, that pulls content from a page that has the same Ditto tag on it (or in the template attached to it).

Finally, if your memory limit is 32M or less, Ditto and some other snippets can exhaust it in their normal operation. Try increasing the memory_limit setting in php.ini.

You need to turn of magic_quotes_gpc. Look here.

Create the URL with $modx->makeURL() like this:

$url = $modx->makeUrl($id, '', 'paramName=value');

The FAQ uses some JavaScript code from DynamicDrive.com and is extremely easy to create and maintain in MODX thanks to the EZfaq Snippet, created by (ahem) me. Go here to see the EZfaq tutorial.
