Here is a good way to use {loadposition} inside another module without hacking core files or using extensions in Joomla…
1) First copy templates/system/html/modules.php into your_template/html/ override folder so we don't change the core file.
2) Then copy the loadposition plugin code (see below) into this file as new functions.
3) I change reference to plgContentLoadModule, plgContentProcessPositions and plgContentLoadPosition to plgModuleLoadModule, plgModuleProcessPositions and plgModuleLoadPosition so we don't get conflict with the actual loadposition functions.
4) I also change reference to $row->text to $module->content
5) I then call the function plgModuleLoadModule($module, &$params); to replace the module content with the new content with the loadposition content in it. e.g.
<?php $module->content = plgModuleLoadModule($module, &$params); ?>
Code to add into modules.php:-
function plgModuleLoadModule( &$module, &$params, $page=0 )
{
$db =& JFactory::getDBO();
// simple performance check to determine whether bot should process further
if ( JString::strpos( $module->content, ‘loadposition’ ) == false ) {
return $module->content;
}
// expression to search for
$regex = ‘/{loadpositions*.*?}/i’;
$pluginParams = new JParameter( $plugin->params );
// check whether plugin has been unpublished
if ( !$pluginParams->get( ‘enabled’, 1 ) ) {
$module->content = preg_replace( $regex, ”, $module->content );
return true;
}
// find all instances of plugin and put in $matches
preg_match_all( $regex, $module->content, $matches );
// Number of plugins
$count = count( $matches[0] );
// plugin only processes if there are any instances of the plugin in the text
if ( $count ) {
// Get plugin parameters
$style = $pluginParams->def( ‘style’, -2 );
plgModuleProcessPositions( $module, $matches, $count, $regex, $style );
}
return $module->content;
}
function plgModuleProcessPositions ( &$module, &$matches, $count, $regex, $style )
{
for ( $i=0; $i < $count; $i++ )
{
$load = str_replace( ‘loadposition’, ”, $matches[0][$i] );
$load = str_replace( ‘{‘, ”, $load );
$load = str_replace( ‘}’, ”, $load );
$load = trim( $load );
$modules = plgModuleLoadPosition( $load, $style );
$module->content = str_replace($matches[0][$i], $modules, $module->content );
}
// removes tags without matching module positions
$module->content = preg_replace( $regex, ”, $module->content );
return $module->content;
}
function plgModuleLoadPosition( $position, $style=-2 )
{
$document = &JFactory::getDocument();
$renderer = $document->loadRenderer(‘module’);
$params = array(‘style’=>$style);
$contents = ”;
foreach (JModuleHelper::getModules($position) as $mod) {
$contents .= $renderer->render($mod, $params);
}
return $contents;
}
