The Sha1 validator checks the content of a transferred file by
hashing it. This validator uses the hash extension for PHP with the
sha1 algorithm. It supports the following options:
-
*: Takes any key or use a numeric array.
You can set multiple hashes by passing them as an array. Each file is checked, and the validation will fail only if all files fail validation.
Example 412. Using the sha1 Validator
<?php
$upload = new Zend_File_Transfer();
// Checks if the content of the uploaded file has the given hash
$upload->addValidator('sha1', false, '3b3652f336522365223');
// Limits this validator to two different hashes
$upload->addValidator('Sha1',
false, array('3b3652f336522365223',
'eb3365f3365ddc65365'));
