Complex Field Queries [SOLVED] was created by Brat

Hello again. Please excuse if this question is repetitious; I couldn't find an answer.

I'm slowly but surely working my way through a very wild project using Flexicontent. I'm finding that a large part of my problem is with SQL field queries.

Example: I want to create a field which will populate a select list using a query such as:

Code:

SELECT [whatever item] FROM [some table] WHERE author = $user->id

In the very crude example above, $user->id would be the front end user who is now using the entry form. I can run simple queries and ones involving JOIN (which made me very happy), but I don't know how to add a query to a field like in the example.

For now, I'm using some jQuery in order to manipulate my items, and it's working, but I'd really prefer to construct do this in a query and make things a lot simpler.

Is it possible for me to write a query like this for a Flexicontent field?

If not, is this a query that must be run in my custom form.php file? If so, how would I create a select list that could then be passed by the form upon submit? Thanks! 8-)

It a good idéal but i thinks its not possible ... wihtout hard modification
Maybe use universal module to modify and display it content

Like the our support? (for a bug-free FC, despite being huge extension) Like the features? Like the ongoing development and future commitment to FLEXIcontent?

Example for item titles:

Code:

SELECT c.id AS value, c.title AS text FROM #__content AS c WHERE created_by=62

(USERID 62 is the administrator) It is possible to create replaceable tags for the query e.g. current user {userid} but the userid of currently editing user is different from that of the currently viewing user, so the replacement will not have the results you expect.

A more meaningful replacement could be {itemowner} which will be the userid of the item owner

Code:

SELECT c.id AS value, c.title AS text FROM #__content AS c WHERE created_by={itemowner}

in selectmultiple.php in folder plugins/flexicontent_fields replace:

Code:

if ($sql_mode) { // SQL mode
 ...
} else { // Elements mode

with:

Code:

if ($sql_mode) { // SQL mode
	
	$db =& JFactory::getDBO();
	$jAp=& JFactory::getApplication();
	$itemowner = $item->created_by;
	
	$query = preg_match('#^select#i', $field_elements) ? $field_elements : '';
	$query = str_replace("{itemowner}", $itemowner, $query);
	
	$db->setQuery($query);
	$options = $db->loadObjectList();
	if (!$options) {$jAp->enqueueMessage(nl2br($db->getErrorMsg()),'error'); return;}
			
	if (!$query || !is_array($options)) {
		$field->html = JText::_('FLEXI_FIELD_INVALID_QUERY');
	} else {
	
		$field->html	= JHTML::_('select.genericlist', $options, $field->name.'[]', 'multiple="multiple" class="'.$required.'"'.$size, 'value', 'text', $field->value);
	}

} else { // Elements mode

i will add more of these into the select(multiple) Fields for v1.5.6

Regards

And also forgot to mention that probably the item will be viewed by unlogged users too (unless you limit access to it). Maybe you meant item-owner in the first place ...
