How to show all published polls?

Post by lekvarnik » Fri Mar 26, 2010 9:51 am

Hi, I don't want to give my client rights to change my modules settings in admin (I have achieved it through som if else statements in toolbar helper file). I just want to allow them make a poll and publish it (green "nike" tick sign ;).

And then I want to show all published polls on my page (of course I must tell the client that he must unpublish the old poll).

So, I would like to know which statement and where (in which files) should I write the code to make this stuff work.

Thanks in advance.

I propose that it must be set up somewhere in poll module php files, somewhere where it selects queries from database and put there .AND published="1" or something like that.

Anybody? :(

I have changed the code in modules/mod_poll/helper.php

Code: Select all

class modPollHelper
{
	function getPoll($id)
	{
		$db		=& JFactory::getDBO();
		$result	= null;

		$query =  'SELECT id, title'
		
			//'SELECT id, title,'

			;
		$db->setQuery($query);
		$result = $db->loadObject();

		if ($db->getErrorNum()) {
			JError::raiseWarning( 500, $db->stderr() );
		}

		return $result;
	}

	function getPollOptions($id)
	{
		$db	=& JFactory::getDBO();

		/*
		$query = 'SELECT id, text' .
			' FROM #__poll_data' .
			' WHERE pollid = ' . (int) $id .
			' AND text <> ""' .
			' ORDER BY id';
		$db->setQuery($query);
		*/
		
		$query = 'SELECT id, text' .
			' FROM #__poll_data' .
			//' WHERE pollid = ' . (int) $id .
			// ' AND text <> ""' .
			' WHERE text <> ""' .
			' ORDER BY id';
		$db->setQuery($query);



		if (!($options = $db->loadObjectList())) {
			echo "MD ".$db->stderr();
			return;
		}

		return $options;
	}
}
?>
I have changed it this way, and know it shows title of published poll but the options are messed up together from all polls in one big vertical column. Damn. I need some help. Please, some gurus give me some advice how to solve this problem. Thanks

Re: How to show all published polls?

How can I do such thing?

I want that my client can make as many polls as possible and also be able to publish them as well. (all through the component in admin /administrator/index.php?option=com_banners ). This is possible and no problem at all.

What is problem with the big "P" is this fact that all plugins that are published will be shown through poll module on the frontpage. So, not just the one which must be set manually in admin (it can be different in your Joomla /administrator/index.php?option=com_modules&client=0&task=edit&cid[]=34) for the poll module.

So, the mechanism of selecting data from the poll table should be modified. I think in the file modules/mod_poll/helper.php or am I wrong? And how?

Any help will be appreciated ;)

After some investigation I find out that my select should be able to do this:

we have 2 tables

jos_polls
jos_poll_data


from the 1st table jos_polls we must select rows where published="1"

and in the same tame in the 2nd table jos_poll_data is pollid equal to id from the first jos_polls table

How will this code look like when we want to do the above stuff? :(

class modPollHelper
{
function getPoll($id)
{
$db =& JFactory::getDBO();
$result = null;

$query =

'SELECT id, title,'
.' CASE WHEN CHAR_LENGTH(alias) THEN CONCAT_WS(\':\', id, alias) ELSE id END as slug '
.' FROM #__polls'
.' WHERE id = '.(int) $id
.' AND published = 1'
;
$db->setQuery($query);
$result = $db->loadObject();

if ($db->getErrorNum()) {
JError::raiseWarning( 500, $db->stderr() );
}

return $result;
}

function getPollOptions($id)
{
$db =& JFactory::getDBO();


$query = 'SELECT id, text' .
' FROM #__poll_data' .
' WHERE pollid = ' . (int) $id .
' AND text <> ""' .
' ORDER BY id';
$db->setQuery($query);


if (!($options = $db->loadObjectList())) {
echo "MD ".$db->stderr();
return;
}

return $options;
}
}
?>

$dboi = new ps_DB;
$q_oi = "SELECT * FROM #__{vm}_product, #__{vm}_order_item, #__{vm}_orders ";
$q_oi .= "WHERE #__{vm}_product.product_id=#__{vm}_order_item.product_id ";
$q_oi .= "AND #__{vm}_order_item.order_id='$order_id' ";
$q_oi .= "AND #__{vm}_orders.order_id=#__{vm}_order_item.order_id";
$dboi->query($q_oi);

On this example from virtumart I see that thay select all objects from multiple tables

and compere them. How should I apply this on my example thx in advance.

If you modify the XML file you can set the default options and remove the users ability to change the module parameters, however the client would still be able to change the poll itself.

So you might want to look into externally hosted polls, which allow you to use those either in the mod_custom or in custom created module without any parameters.

in the modules you can search for compoents with a certain name, e.g.:
http://[your-domain].com/administrator/index.php?option=com_modules&filter_type=mod_poll
