Same name and namespace in other branches

1. 6 hooks/emfield.php \EMMODULE_PROVIDER_validate()
2. 6.2 hooks/emfield.php \EMMODULE_PROVIDER_validate()

Validate the provider's embedded code.

This allows each provider to determine whether a pasted URL that otherwise matches a parse attempt from EMMODULE_PROVIDER_extract is valid. For instance, the provider file might check against the third party provider's API to ensure a video still exists. If the validation is to fail, the function should call form_set_error with the provided $error_field.

Parameters

$code: The unique identifier for the third party media. @param $error_field The form field to use with form_set_error().
