Question

It’s show following error:

Notice: Undefined offset: 1 in C:\xampp\htdocs\evantechbd\secure\content\feature_link_process.php on line 28.

Why it’s show the error…? Can anyone tell me… Here is the 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<br>';             
}

Answer 1

You will probably want to do something like this, instead:

$errors = array();

if( empty($_POST['coun_name']) )
{
  $errors[] = 'Country Name required.';
}
elseif( strpos($_POST['coun_name'], '|') === false )
{
  $errors[] = 'Country Name invalid.';
}
else
{
  list($coun_name, $coun_id) = explode("|", $_POST['coun_name'], 2);
}

The first condition checks to make sure the user submitted a value for $_POST['coun_name']. The second condition checks to make sure that the value contains a ‘|’ character.

If both conditions are met, $coun_name and $coun_id are populated by explode()‘ing $_POST['coun_name'] as normal (I dropped in a call to list() for brevity).
