Troubleshooting "Undefined offset" error
<p>It's show following error:</p>

<blockquote>
  <p>Notice: Undefined offset: 1 in C:\xampp\htdocs\evantechbd\secure\content\feature_link_process.php on line 28.</p>
</blockquote>

<p>Why it's show the error...? Can anyone tell me... Here is the code:  </p>

<pre><code>$row = explode("|", $_POST['coun_name']);
$coun_id = $row[1]; // cat_id
$coun_name = $row[0];

if(isset($coun)){
    $errors = array();      
    if(empty($coun))
    $errors[] = 'Country Name require&lt;br&gt;';             
}
</code></pre>
