Invalid Argument Supply for foreach

Question

I have a problem in my foreach. I am trying to get the data by category. I have some popular category on my home page. I want when the user click on the catname its show related jobs of that category its fine when data exist but data not found its give me an error invalid argument Supply for foreach.

Here is my controller:

public function catwise($catname){
        $data['jobs'] = $this->edituser_model->getBlogByname($catname); 
        $this->load->view('locwise' , $data);           
    }  

and my Model is:

public function getBlogByname($catname){
        $this->db->select('*');
        $this->db->where('catname', $catname);
        $query = $this->db->get('jobs');

      if($query->num_rows() > 0){
        return $query->result();
      } else {
        return false;
      }

    }

and my view is:

<?php if(count($jobs)): ?>
   <?php foreach ($jobs as  $row): ?> 

      <div class="job-box">
           <div class="company-logo">
      </div>

      <div class="row"> 
            <div class="col-lg-12">

When your model returns boolean, i.e. false, count(false) (true also) equal to 1.

echo count(false);

You should return an empty array, like return [];.
