Insert node to body of another node (filter)

edhel - October 6, 2006 - 08:15

I post text of my quick hack-filter. Syntax:

[node:123] - insert full text (themed by theme('node'))
[node:123 body] - insert node's body
[node:123 teaser] - insert node's teaser
[node:123 link] - insert link to node
[node:123 collapsed] - insert collapsed node's body

Code (put it to file node_filter.module):

<?php
function node_filter_help($section) {
    switch($section) {
        case 'admin/modules#description':
            return t('Filter for including node to body of another node by its ID.');
    }
}

function _node_filter_replacer($matches) {
    $node = node_load(array('nid'=>$matches[1]));
    switch ($matches[2]) {
    case 'body':
        return $node->body;
    case 'teaser':
        return $node->teaser;
    case 'link':
        return l($node->title, "node/$node->nid");
    case 'collapsed':
        return theme('fieldset', array('#collapsible'=>true, '#collapsed'=>true, '#title'=>$node->title, '#value'=>$node->body));
    default:
        return theme('node', $node);
    }
}

function node_filter_filter($op, $delta = 0, $format = -1, $text = '') {
    switch ($op) {
    case 'list':
        return array(0 => t('Include/link node by ID'));
    case 'description':
        return '';
    case 'prepare':
        return $text;
    case "process":
        $text = preg_replace_callback('/\[node:([0-9]+)(?:\s+(body|link|collapsed|teaser))?\]/', '_node_filter_replacer', $text);
        return $text;
    default:
        return $text;
    }
} 
?>
