Adding column to CP entries without writing plugin?

Question

Is there a way to add a column to the control panel display of entries? I would strongly prefer to not write a plug-in for this. The contents in the column would be nothing more than a button that links to a URL containing the UID of the entry. Note, I am not using the Commerce plug-in here.

If I have to write a plug-in, what would be the simplest scaffold to use?

Answer 1

A simple-ish way you could do this is by using the pre-parse field to parse {{ entry.uid }}.

This will then give you an extra column with the unique ID. You can then use Control panel JS to change that into a link/create a button. Something like:

$(document).ready(function() {
    Craft.elementIndex.on('updateElements ', function(data){
        if (data.target.$source.data('handle') == 'your-section-handle') {
            $('td[data-attr=field:your-field-id]').each(function(){
                <!-- JS code to change uid into link -->
            });
        }
    });
});

Replacing your-section-handle and your-field-id.
