make 0 value not treated as empty value

[bbmak]

I have this validation of my form. However, the empty function treats all 0 as empty.  Are there anyway to make 0 as not an empty value?

if (empty($item_name) || empty($item_link) || empty($item_price))
{
$errors[] = 'Item Name, Item Link, and Item Price Cannot Be Empty.';
} else {

                  $validate = new validate();
                  if(!$validate->validateURL($item_link)) {
                  $errors[] = 'This is not a URL.';
                  }


                  if (!is_numeric($item_price)) {
                  $errors[] = 'Item Price Must be a number.';
                  }

       }

or you can use $item_name==''

if (!(isset($item_name)) || !(isset($item_link)) || !(isset($item_price)))
{
$errors[] = 'Item Name, Item Link, and Item Price Cannot Be Empty.';
} else {

                  $validate = new validate();
                  if(!$validate->validateURL($item_link)) {
                  $errors[] = 'This is not a URL.';
                  }


                  if (!is_numeric($item_price)) {
                  $errors[] = 'Item Price Must be a number.';
                  }

       }

print_r($_POST);

or

print_r($_GET);

 

depends on the method specified in the form.

Do you want to allow 0s? Use strlen()

Alliento has the best idea but use  logical == to compare for empty.

if ($item_name=='' || $item_link=='' || $item_price=='')
{
$errors[] = 'Item Name, Item Link, and Item Price Cannot Be Empty.';
} else {

                  $validate = new validate();
                  if(!$validate->validateURL($item_link)) {
                  $errors[] = 'This is not a URL.';
                  }


                  if (!is_numeric($item_price)) {
                  $errors[] = 'Item Price Must be a number.';
                  }

       }
