| − | '''JHTMLGrid class'''
| + | This class is available in the following Joomla versions:- |
| − | '''methods are following'''
| + | <splist showpath=notparent /> |
| − | sort
| + | <noinclude>[[Category:Framework]][[Category:JHTMLGrid]]</noinclude> |
| − | id
| + | |
| − | access
| + | |
| − | checkedOut
| + | |
| − | published
| + | |
| − | state
| + | |
| − | order
| + | |
| − | | + | |
| − | '''sort'''
| + | |
| − | needed someone to write about this.
| + | |
| − | | + | |
| − | '''id method'''
| + | |
| − | This method is used to make checkbox respective to record retrieved from database and displayed to administrator screen. You can use
| + | |
| − | JHTML::_('grid.id', $i, $row->id )
| + | |
| − | and please don't forget to echo this. Use this with loop of record list retrieved by database.

| − | '''published'''
| + | |
| − | I recently experienced with this method and would like you tell about this, that how it can be useful for you to show publish/unpublish icon against record displayed on your screen. Please keep in mind its about administrator side, not client side of Joomla.
| + | |
| − | First you needed a hidden input field with form to which you are working with. This should be named check and it has value post, like this
| + | |
| − | <input type="hidden" name="check" value="post"/> | + | |
| − | then you need this PHP script in column where you want to put this icon
| + | |
| − | echo $published = JHTML::_('grid.published', $row, $i );
| + | |
| − | This will call published method of JHTMLGrid class. It will fire a task named 'publish()' , so you can handle by inserting a function named publish into your controller. Have a look over following
| + | |
| − | function publish()
| + | |
| − | {
| + | |
| − | $cid = JRequest::getVar( 'cid', array(), '', 'array' );
| + | |
| − | $this->publish = ( $this->getTask() == 'publish' ? 1 : 0 );
| + | |
| − |
| + | |
| − | JArrayHelper::toInteger($cid);
| + | |
| − | if (count( $cid ) < 1) {
| + | |
| − | $action = $publish ? 'publish' : 'unpublish';
| + | |
| − | JError::raiseError(500, JText::_( 'Select an item to' .$action, true ) );
| + | |
| − | }
| + | |
| − | $this->cids = implode( ',', $cid );
| + | |
| − |
| + | |
| − | $query = 'UPDATE #__pricequote'
| + | |
| − | . ' SET published = ' . (int) $this->publish
| + | |
| − | . ' WHERE id IN ( '. $this->cids .' )' ;
| + | |
| − | $db =& JFactory::getDBO();
| + | |
| − | $db->setQuery( $query );
| + | |
| − | if (!$db->query())
| + | |
| − | {
| + | |
| − | JError::raiseError(500, $db->getErrorMsg() );
| + | |
| − | }
| + | |
| − | $link = 'index.php?option=com_pricequote';
| + | |
| − | $this->setRedirect($link, "Updated Successfully.");
| + | |
| − | }
| + | |
| − | | + | |
| − | This is function that will update published field value into table.
| + | |
| − | | + | |
| − | That was all I have to write about published method. May be any other can improve this.
