Easy Profile - Joomla Extension

Hi,
after this

$('#jform_selectAlias2').chosen();

try to put this code to fire second select

$('#jform_selectAlias2').change();

Hi,

It has been a while since last post, but I started working on thiss website again and now I have a follow up question. I post it here because I think that it is helpful to see history.

The above scenario/script works like it is intended. I want to add some functionality and for that I need to capture the .change event from the second dropdown.

When I prefill the second list from php I can catch the change event in jquery. But when I change the first select and fill the second from code the change event does not get fired for some reason.

Do you have any ideas why?

Thanks

Hi, I got things working now. I created some component-overrides. I did some tricks on positioning fields and I use my own naming convention subcategory_1 always co-exists with category_1 This way I can add as many category subcategory combo's as I want.
I used some code from he jquery example you provided (I just repeat it on a need to have basis in the php-script)
So, thanks for your help.

Hi,
I would do it with CSS/Javascript code,
example:
the privacy field is nothing more than a normal field with its own dedicated line.
You can check our Javascript code for privacy in components/com_jsn/assets/js/privacy.js (in line 3 and 4 we assign a class privacy to row of each privacy field),
in components/com_jsn/assets/css/style.css you can find our solution to make it stand on the same line of assigned field.

Hi, thanks. I got this working now. I am going to adjust because there will be a few more of this pairs of dependant dropdown select lists.

I am also looking to place the two dropdown select lists next toeach other (on the same line). I am trying to sort it out myself, but if you have any hints/tips it would be appreceated.

Hi, in download area you get the new version 1.2.5

Follow these step:
add to file /administrator/components/com_jsn/hepers/fields/selectlist.php (replace the where of query, see comment)

public static function operations()

		{

			if(isset($_GET['alias']))

			{

				// Load Library

				JFormHelper::addFieldPath(JPATH_ADMINISTRATOR.'/components/com_jsn/models/fields');

				

				// Load Field Params

				$db=JFactory::getDbo();

				$query = $db->getQuery(true);

				$query->select('a.*')->from('#__jsn_fields AS a')->where("a.alias = '".$_GET['alias']."'");

				$db->setQuery( $query );

				$field = $db->loadObject();

				$registry = new JRegistry;

				$registry->loadString($field->params);

				$field->params = $registry;



				// Create a form Object with field XML

				$form=new JForm('jform',array('control' => 'jform'));

				$xml='<form>'."\n";

				$xml.=JsnSelectlistFieldHelper::getXml($field);

				$xml.="\n".'</form>';

				$xml=new SimpleXMLElement($xml);

				$form->load($xml);

				

				// Set Where From HTTP

				$form->setFieldAttribute($_GET['alias'], 'dboptwhere','state=1 AND catid='.$_GET['catid']); // replace 'state=1 AND catid='.$_GET['catid'] with your query



				// Get Input

				echo($form->getField($_GET['alias'])->input);

			}

		}

add this javascript to your jQuery(document).ready() (replace selectAlias1 with your select category alias and selectAlias2 with your select value alias, maybe replace $ with jQuery )

$('#jform_selectAlias1').change(function(){

			$.ajax({

					url : "index.php?option=com_jsn&view=opField&type=selectlist&alias=selectAlias2&format=raw&catid="+$(this).val(),

					success : function (data,state) {

						var val=$('#jform_selectAlias2').attr('data-val');

						$('#jform_selectAlias2').parent().html(data);

						$('#jform_selectAlias2').val(val).attr('data-val',val);

						$('#jform_selectAlias2').chosen();



					}

			    })

			});

		$('#jform_selectAlias1').change();

My test:
I have created select 1 with this parameter:
condition 1: if equal to custom value (empty) hide select 2 // if this field is empty not show select 2
table: #__categories
column value: id
column text: title
sql where: extension='com_content' AND published=1 //because #__categories contains all category not only for article

I have created select 2 with this parameter
table: #__content
column value: id
column text: title
sql where: id=0 //because otherwise you load all record of table before filter by category, this is not a problem but weighs down the page to load

Hi,
Thank you that is good news. I was setting up a test site for you to connect to. I will continue setting this up but will wait for the update/code before I do more testing.
Thanks

Hi,
today we will release new version with get option from DB feature for selectlist. we will send you a code to do this (tested and work).

Sorry for late reply
It's late for us and our office closed.

Please post me your site link to check javascript code and getoption function that you have implemented.

Also please specify a valid catid parameter to insert in http query.

Hi, I have php knowledge and I think I must be able to code this. Thanks for pointing me in the right direction. I am going to start and try to work it out.

No Sorry,
but if you hare a developer you can do this:
- create first select (category) - alias: select1
- create second select (element) - alias: select2
- add to file /administrator/components/com_jsn/hepers/fields/selectlist.php in main class this function

public static function operations()

	{

		if(isset($_GET['alias']))

		{

			// Load Field Params

			$db=JFactory::getDbo();

			$query = $db->getQuery(true);

			$query->select('a.*')->from('#__jsn_fields AS a')->where("a.alias = '".$_GET['alias']."'");

			$db->setQuery( $query );

			$field = $db->loadObject();

			$registry = new JRegistry;

			$registry->loadString($field->params);

			$field->params = $registry;

			

			// Create a form Object with field XML

			$form=new JForm('jform');

			$xml='<form>'."\n";

			$xml.=JsnSelectlistFieldHelper::getXml($field);

			$xml.="\n".'</form>';

			$xml=new SimpleXMLElement($xml);

			$form->load($xml);

			

			// Get Input

			echo($form->getField($_GET['alias'])->input);

		}

	}

- You must set in getOptions function (previous post) a dinamically query for select2 to get options based $_GET['catid']

- Now add Javascript: when you choose select1 you can launch a ajax request to replace select2 (without value) with new select2 (with new category value).
You must get this url: index.php?option=com_jsn&view=opField&type=selectlist&alias=select2&format=raw&catid=**select1_value_genrated_by_javascript**
with view=opField and type=selectlist Easy Profile call a 'operation' function of selectlist.

We have predict the functions for loading the fields via Ajax.

NOTE:
1. You must have PHP Knowledge
2. We do not give support for these changes
