I try to call a model from one of my Joomla controller but that doesn't seem to work.
class TieraerzteControllerDatatable extends JControllerLegacy
{
/**
* display task
*
* @return void
*/
function display($cachable = false)
{
// set default view if not set
$input = JFactory::getApplication()->input;
$model = $this->getModel('datatable');
$model->getTableData('grumpi_tieraerzte', 'id', array('id','name','strasse','telefon','fax'));
die();
}
}
In my model I placed a var_dump but it is not accessed. How can I debug my model call in controller?
I try to access the models return with the following url /administrator/index.php?option=com_tieraerzte&task=datatable.display&{arguments for the model}
trying to debug my codes piece by piece seems like the model is accessed and this code is causing the problem
// Paging
$sLimit = "";

{
$sLimit = "LIMIT " . intval(JRequest::getVar('iDisplayStart')) . ", " . intval(JRequest::getVar('iDisplayLength'));
}
The whole method:
public function getTableData($table, $index_column, $columns)
{
$db = JFactory::getDbo();
$query = $db->getQuery(true);
// Paging
$sLimit = "";

}
// Ordering
$sOrder = "";
if (isset(JRequest::getVar('iSortCol_0')))
{
$sOrder = "ORDER BY ";
for ($i = 0; $i < intval(JRequest::getVar('iSortingCols')); $i++)
{
if (JRequest::getVar('bSortable_' . intval(JRequest::getVar('iSortCol_' . $i))) == "true")
{
$sortDir = (strcasecmp(JRequest::getVar('sSortDir_' . $i), 'ASC') == 0) ? 'ASC' : 'DESC';
$sOrder .= "`" . $columns[intval(JRequest::getVar('iSortCol_' . $i))] . "` " . $sortDir . ", ";
