Message: Invalid argument supplied for foreach in CodeIgniter

Question

i am facing few issues during an application of Codeigniter -- Created an function like

function searchUnivtab() {
        $country = $this->input->po         


        

Answer 1

Remove @ in the following line to see if it produces any error so replace

$data = @$this->get->getSearchedUniversityTab($country, $state, $level, $degType[1]);

with

$data = $this->get->getSearchedUniversityTab($country, $state, $level, $degType[1]);
