I found a few posts on this subject, but found no direct example code, so I thought I would share this.
I was developing a WP theme to integrate with a MODx site, and wanted to include my fully parsed site header and footer elements. I could have created modx documents that contained nothing but the elements I was after, as GaneshXL recently suggested, then include them into the WP theme. But I decided to try getting the modx parser up and running inside WP instead. I think this solution may weigh a little less because it doesn’t include files via http, and when the modx parser runs, I’m not running the entire thing. At the same time, I haven’t dug deeply into the caching ramifications, so maybe running this modified parser on each WP page could be more costly depending on the site in question.
I had my header and footer coming from chunks named Header and Footer. You can use this technique to grab and parse anything in your modx site though.
Luckily, the html template was built so that both the header and footer html could be included in on WP theme file - footer.php.
What follows is sort of a "mini" modx parser. A lot of what modx normally does is not required (figuring out doc id, checking doc permissions and so on). At the same time, I had to take additional steps to make it work inside a WP theme file (e.g. dealing with globally scoped variables). There is probably a better way than putting it right in a theme template file like this - if anyone can point that out to me, please do and I will improve the solution. This is what I ended up with after a couple of hours of hacking around
<?php
/**
* this goes at the top of a WP theme template file, e.g. footer.php
*/
// next line assumes that modx is installed in site root, and WP is a subdirectory off root (e.g. /blog/)
define('MODX_BASE_PATH', dirname(dirname(dirname(dirname(dirname(__FILE__))))) . '/');
define("IN_PARSER_MODE", "true");
define("IN_MANAGER_MODE", "false");
if (!defined('MODX_API_MODE')) {
define('MODX_API_MODE', true);
}
// initialize the variables prior to grabbing the config file
$GLOBALS['database_type'] = 'mysql';
$GLOBALS['database_server'] = 'localhost';
$GLOBALS['database_user'] = 'xxxxxxxxxx';
$GLOBALS['database_password'] = 'yyyyyyyyy';
$GLOBALS['dbase'] = 'zzzzzzzzzz';
$GLOBALS['table_prefix'] = 'modx_';
$GLOBALS['base_url'] = 'http://www.xxxx.com/';
$GLOBALS['base_path'] = '/home/xxxx/public_html/';
define('MODX_BASE_URL', $GLOBALS['base_url']);
define('MODX_SITE_URL', $GLOBALS['base_url']);
$ipath = ini_get('include_path');
ini_set('include_path', $ipath . ':' . $GLOBALS['base_path']);
// initiate a new document parser
include_once($GLOBALS['base_path'].'manager/includes/document.parser.class.inc.php');
$GLOBALS['modx'] = new DocumentParser;
$modx =& $GLOBALS['modx'];
$etomite = &$GLOBALS['modx']; // for backward compatibility
// set some parser options
$modx->minParserPasses = 1; // min number of parser recursive loops or passes
$modx->maxParserPasses = 10; // max number of parser recursive loops or passes
$modx->dumpSQL = false;
$modx->dumpSnippets = false;
$modx->tstart = $tstart; // feed the parser the execution start time
$modx->getSettings();
$modx->documentMethod = 'id';
$modx->documentIdentifier = 10;
// header
$modx_header= $modx->rewriteUrls($modx->parseDocumentSource('{{Header}}'));
// footer
$modx_footer= $modx->rewriteUrls($modx->parseDocumentSource('{{Footer}}'));
A couple of things I want to point out...
I use a weblink in modx to point to the wp blog. That weblink’s doc id is 10, which is why in the above code, I have explicitly set $modx->documentIdentifier = 10. When the Header chunk renders, Wayfinder outputs the menu as if we’re there on that modx doc (i.e. makes the Blog menu item active).
The last couple of lines show how easy it is to parse anything at all. Inside both ->parseDocumentSource calls, you can see just raw chunk tags. Modx parses thoses, runs snippets etc etc.
Please feed back especially with critical comments. I might reuse or generalize this solution further.
