Question

I’ve got a form for a job application, where administrator needs to pick from the list of certain user ids. The list contains only user ids of type “employer”, however I want to validate the administrator input, so if he manually inserts an id that doesn’t exist or is for user of different type than “employer”, the validation should fail. I thought that code to do this would be:

new Zend_Validate_Db_RecordExists(
    array(
        'table' => 'users',
        'field' => 'id',
        'exclude' => "mode != 'employer'"
    )
)

so, I’m searching for all the records in table users, excluding those where mode != ’employer’ – if such record exists, where id is equal to the one picked from input, it passes the validation. However, the code above doesn’t work – I have to do 'exclude' => "mode = 'employer'", so exclude actually equals where statement. My understanding of the logic here is wrong – can somebody tell me why?

PHP: 5.2.17, Zend: 1.10.4

EDIT: (the comment to @ro ko enquiries, as it probably clears things out)

Please find the table and sample code here: http://pastebin.com/C7AXMNTZ . In my understanding this should return valid for Joker (is employer), but false for Kingpin (not employer) and Poison Ivy (not in the db) – as you can see the results are not what I’m expecting.

Answer 1

As per documentation (search for The above example will check the table to ensure no records other than the one where id = $user_id contains the value $username.) the exclude option indeed works as WHERE statement.

I can only say that whoever though that using such keyword for this functionality is a good idea had a wicked sense of humor.
