Modifying Universal Module to Accept Form Entry was created by sadie199

I'm trying to modify the Flexicontent Universal Module to accept a form submission. In other words, I want to use the tag scope to display information, but I want the tags used to be selected by the user in a multi-select form.

So, the user will see a list of available tags, select two on which to base the tag scope display of the module.

In helper.php, the line that pulls the tag_ids parameter from the database appears to be:

// tags scope parameters
$method_tags = (int)$params->get('method_tags', 1);
$tag_ids = $params->get('tag_ids', array());
$tag_ids = (!is_array($tag_ids)) ? array($tag_ids) : $tag_ids ;

Can I modify this line so that it uses the form data submitted instead of pulling from the database? Something along the lines of $_POST[tag_ids]?

Thank you!

i am sorry, i have read your original message wrongly,
I have deleted my answer above as it was answering something different

and actually your request is interesting, as it would add great flexibility to the module

in a future version we will think how to make such a feature accessible to the end-user (non-developer)

You can do what you suggested like this ...

1. To retrieve the tag ids from the post array inside the module use:

Code:

<?php
$module_id = '45';
$fieldname = 'fc_tag_ids_'.$module_id;
$fc_tag_ids =  JRequest::getVar($fieldname, false);
if ($fc_tag_ids) {
  $fc_tag_ids = is_array($fc_tag_ids) ? $fc_tag_ids : array($fc_tag_ids);
  $tag_ids = $fc_tag_ids;
}
?>

2. To create a form field element that contains the tags use:

Code:

<?php
	$query = 'SELECT id AS value, name AS text'
	. ' FROM #__flexicontent_tags'
	. ' WHERE published = 1'
	. ' ORDER BY name ASC, id ASC'
	;
	
	$db->setQuery($query);
	$tags = $db->loadObjectList();
	
	$attribs = ' multiple="multiple" ';
	
	$fcmodule_id = '45';
	$fieldname = 'fc_tag_ids_'.$fcmodule_id;
	$element_id = $fieldname;

	$values = JRequest::getVar($fieldname, array());
	
	$tags_field = JHTML::_('select.genericlist', $tags, $fieldname, $attribs, 'value', 'text', $values, $element_id);
	echo $tags_field ;
?>

Please use form field name fc_tag_ids, as i WILL ADD this to the module in next version, but note that i will probably make it:
$form_name = 'fc_tag_ids_'.$module_id;
or something this way you will be able to upgrade to a module that needs no changes
