function theme_field__content_type() isn't working I'm trying to modify all fields output for a specific content-type called Netrunner-Card.

After digging through Stack Exchange I ran across someone that suggested using:

function theme_field__content_type()


But it isn't working. My implementation is:

function blinks_responsive_field__netrunner_card($variables)
{
    $output = 'TEST';
    return $output;
}


Which if I understand correctly, this should remove all field data for a content type of 'Netrunner Card' but it doesn't.

I have multiple fields for each card. There are also card types which I want to output differently, (i.e. An Operation card should look like this, an Identity card should look like this, etc.). So I want to use a switch function (PHP) to check the card types and adjust fields as needed. First I have to get access to the fields and I'm trying to do this inside of ONE function versus a separate function for each field which would add a lot of duplication.

My theme is called blinks_responsive. My content type is netrunner_card.
I am out of ideas.

UPDATE: I don't know if it matters but I discovered that I had a field.tpl.php file in my theme templates folder. Wondering if that caused me issues. Still not working tho.
The problem lies in having other functions that alter OTHER fields of the SAME content type.

Earlier in my development, I created two functions, one each, for two specific fields. Even though my adjustments for those fields were minor (added classes to one and added an img tag to another) it still caused the generic function to fail.

Because I had those other functions...

theme_field__field_name__content_type


It made the generic function for all fields...

theme_field__content_type


...not work.

Once I removed those other functions? Suddenly theme_field__content_type started working instantly.
