注意：未定义的属性：stdClass

I have problem in my script with:

Notice: Undefined property: stdClass::$job_details in /Applications/MAMP/htdocs/curafides/home.php on line 1034

How can I fix this problem? Example for job_title not sgh <?php echo $jb_row->job_title?>

And for job_details :

<?php

    if(strlen($jb_row->job_details) > 120) {
        echo substr($jb_row->job_details ,0 ,120)."...";
    } else {
        echo $jb_row->job_details;
    }

?>

Try something like below:

if( isset($jb_row->job_details)  && strlen($jb_row->job_details) > 120){
   echo substr($jb_row->job_details ,0 ,120)."...";
}else{
  echo $jb_row->job_details;
 }
