add callback to form submit? | WordPress.org

Is there a way to hook up a callback to a form submission or field submission? I’d like to do some processing when certain forms are submitted, depending on the values passed in.

In some cases, it’s enough just to check the field value on every page load and process if I need to. But sometimes we don’t want to react to the submitted value every time – just one time.

For example, I want to have a sub-item/page where the user downloads a file in a format that I will create. I don’t want the download to start every time that sub-page loads, just when they click the Export button.

Thanks.

Nevermind. Just found it. http://admin-page-framework.michaeluno.jp/en/v3/class-AdminPageFramework.html

I believe I just have to create a function like submit_{instantiated class name}_{submit input id}

Wrong answer above. I figured out that in the setUp method that I need to explicitly do add_action and point to a method to run when a certain submit button is clicked. E.g.
add_action( 'submit_MyClass_global_process_extracts', array( $this, 'process_extracts' ) );

However I still have an issue that I can’t seem to work around. If in my hook method process_extracts I need to access the data saved on that page, that data is not yet accessible via AdminPageFramework::getOption( 'MyClass' ); This seems strange. I need to call a method after a page has been saved to do extra processing on the files uploaded there.

Any help would be greatly appreciated.

Sounds like you want to use the validation callbacks.

There is a tutorial on it.

Another example of validation_{…} hooks:

Hope it helps!
