Question

This is my code

$adapter = new Zend_File_Transfer_Adapter_Http();
$adapter->addValidator('Extension', false,
                array('extension' => 'exe, php, pl, js, html, htm', 'case' => false));
if (!$adapter->isValid())
{
   return 'ERROR';
}

When I try to upload jpg or txt file I get ‘ERROR’ string. Looks like $adapter->isValid() return false. Should it return true?

What is wrong in my code?

Answer 1

The main problem is that you are trying to upload a jpg or txt file, but neither of those extensions are allowed in the list. You are only allowing exe, php, pl, js, html, or htm.

There is also a small problem with the way the extensions are set in the array having spaces between them. I inspected the values and ZF had the list of extensions you supplied, but every one except the first was preceded by a space.

Either of the following two options will work:

// array method
$adapter->addValidator('Extension', false,
                       array('txt', 'jpg', 'jpeg', 'exe',
                             'php', 'pl', 'js', 'html', 'htm',
                             'case' => false));

// or

// string method
$adapter->addValidator('Extension', false,
                       'txt,jpg,jpeg,exe,php,pl,js,html,htm');
