Adding "empty_label" parameter to PredefinedOptions tag

[Alexander Obuhovich]

Tag PredefinedOptions is used to output all options, associated with a given field, e.g.

• country list
• state list
• possible link statuses (Active, Pending, Disabled)

It has several special parameters:

• "has_empty" - adds first empty option before other options
• "empty_value" - value of first empty option

Problem is that there is no way to specify that empty options's text. Now there is with this patch and new "empty_label" parameter.

Task: http://tracker.in-portal.org/view.php?id=1164

Ready for testing.

This is really cool and useful!

Can I specify a plain text and not the label in empty_label? Example, using +just test? That would be really cool too!

Nope, label only for now. In all projects, that I was involved in I needed a label to be displayed instead 1st option, especially, when list of dropdown values are not labels at all (e.g. "None" (lu_None), "Please Select").

Yes, this would be helpful in some case, as optgroup label is not displayed as empty value, but only when clicking to see all choices.

Hi guys,

Here is a little improvement to Alex's patch so it supports Plain Text Empty Option (ie. +please select, where + indicated that it's a non-label phrase)

Alex, please review if this can be included / committed to 5.2.0 branch

Seems ok, but use same function for string cutting in all patch, e.g. use "substr" or "mb_substr" in all 2 places.

Also you haven't attached this patch to the task.

Thanks for review.

Update patch attached here and the task.
