Image & File Dependencies

Image & File Dependencies

Allows Image and File fields to be used in inputfield dependency selectors. Note: prefix field names with an underscore in your dependency selectors.

Usage

Install the ImageFileDependencies module.

You can now create an inputfield dependency based on the number of images or files added to a Image or File field.

When you create an inputfield dependency for a Image or File field, prefix your field name with an underscore. Example for a field named 'images': _images>3
Note that you do not include a '.count' subfield in the selector.

Oh yes, this is great! Thanks for sharing

@szabesz, glad you approve. I have plans for another module relating to inputfield dependencies. Watch this space.

@Robin S looks great, thanks. Can you name a use case?

On a side note: What are you using to record the screen and export to gif? I tried gifrocket, but even with a small framerate, files get pretty large. Yours is tiny, I like it.

Maybe this one (LICEcap)?

The use cases are the same as those for any inputfield dependency: you want to show or require one field based on the state of another. This module just adds Image and File fields to the types of fields you can use in an inputfield dependency selector.

Off the top of my head: you have an images field for an optional gallery and you want to remind the site editor to add a summary/introduction for the gallery if images are added. Also, there was this request for help.

@szabesz is right - the screen recorder tool is LICEcap. I discovered it via this post by @bernhard.

@Robin S you're my hero again for this module! Seriously every time I think of something I need in PW you're already on it.

Hello, is this module still necassary with newest PW ?

What ist actually the best way to show a text input field only if an image field ist populated? This image field is set to "single file if populated, null if not".  Additional the text input should be "required" if the image field is populated. 

Any help is appreciated...

I'm not aware of anything changing that would make this module redundant, but it will be easy for you to check and find out.

When using the Image & File Dependencies module, if your image field is named "image" you would use the selector string:

_image>0

Thanks for your reply and the module!  I will give it a try...
