Parsing MODX Tags

In some cases you'll need to parse snippet, chunk or lexicon tags outside of the regular parsing flow. For example when generating email content, or when building an API that needs to return fully-processed content.

When doing so, you may notice that modX::getChunk only processes regular [[+placeholders]], and not all other valid tags contained in the chunk.

In those cases, you can use the modParser to complete processing:

// First render a chunk, which processes the provided placeholders
$content = $modx->getChunk('MyChunkName', ['foo' => 'bar']);

// Get the modParser instance
$parser = $modx->getParser();

// Define how deep we can go
$maxIterations= (integer) $modx->getOption('parser_max_iterations', null, 10);

// Parse cached tags, while leaving unprocessed tags in place
$parser->processElementTags('', $content, false, false, '[[', ']]', [], $maxIterations);
// Parse uncached tags and remove anything that could not be processed
$parser->processElementTags('', $content, true, true, '[[', ']]', [], $maxIterations);

return $content;
