Sorting in Joomla Explained

by Bhumi // Jan 15,2013 // No comment

Recently I am working on one project and i wanted to provide sorting save and edit option to the title in joomla website.

In this Joomla,Nivoslider plugin used for slider and i wanted to add sorting option to the ordering field.so i have just checked and get that same functionality provided by article section in joomla so I have checked code and use it.

Let’s see how i use the code to develop edit and save sorting option in joomla.

First of all, I have replaced two variable defined in top of the page are $canOrder and $saveOrder and added $params


$canOrder	= true;
$saveOrder	= $listOrder == 'a.ordering';

$canOrder = true;

$saveOrder = $listOrder == 'a.ordering';

with below line of code


$canOrder	= $user->authorise('core.edit.state', 'com_contact.category');
$saveOrder	= 'ordering';
$params	= (isset($this->state->params)) ? $this->state->params : new JObject();

$canOrder = $user->authorise('core.edit.state', 'com_contact.category');

$saveOrder = 'ordering';

$params = (isset($this->state->params)) ? $this->state->params : new JObject();

Next, I have replaced title with link so when user click on it,save option will be enable.Let’s see below line of code


<?php echo JText::_('JGRID_HEADING_ORDERING')?>

1 2	<?php echo JText::_('JGRID_HEADING_ORDERING')?>

replaced with following line of code


<?php echo JHtml::_('grid.sort',  'JGRID_HEADING_ORDERING', 'ordering', $listDirn, $listOrder); ?>
<?php if ($canOrder && $saveOrder): ?>
   <?php echo JHtml::_('grid.order',  $this->items, 'filesave.png', 'items.saveorder'); ?>
<?php endif;?>

<?php echo JHtml::_('grid.sort', 'JGRID_HEADING_ORDERING', 'ordering', $listDirn, $listOrder); ?>

<?php if ($canOrder && $saveOrder): ?>

<?php echo JHtml::_('grid.order', $this->items, 'filesave.png', 'items.saveorder'); ?>

<?php endif;?>

then after,Go to the the middle of the page where loop is used there was some variables which are just defined as true like


$canCreate	= true; 
$canEdit	= true;
$canCheckin	= true; 
$canEditOwn	= true; 
$canChange	= true;

$canCreate = true;

$canEdit = true;

$canCheckin = true;

$canEditOwn = true;

$canChange = true;

Same here , replace above variables with below line of code


$canCreate = $user->authorise('core.create',		'com_contact.category.'.$item->catid);
$canEdit = $user->authorise('core.edit',			'com_contact.category.'.$item->catid);
$canCheckin =$user->authorise('core.manage',		'com_checkin') || $item->checked_out == $userId || $item->checked_out == 0;
$canEditOwn = $user->authorise('core.edit.own',		'com_contact.category.'.$item->catid) && $item->created_by == $userId;
$canChange = $user->authorise('core.edit.state',	'com_contact.category.'.$item->catid) && $canCheckin;

$canCreate = $user->authorise('core.create', 'com_contact.category.'.$item->catid);

$canEdit = $user->authorise('core.edit', 'com_contact.category.'.$item->catid);

$canCheckin =$user->authorise('core.manage', 'com_checkin') || $item->checked_out == $userId || $item->checked_out == 0;

$canEditOwn = $user->authorise('core.edit.own', 'com_contact.category.'.$item->catid) && $item->created_by == $userId;

$canChange = $user->authorise('core.edit.state', 'com_contact.category.'.$item->catid) && $canCheckin;

That’s about it. I want to say a huge thanks to various sources around the web that I visited while trying to evaluate how to create this code. I’m sure someone there has done this already & probably done it better, but I just wanted to share how I did it and hopefully it will help someone
