#20801 closed defect (bug) (fixed)

Deprecating PHP4-style constructors gracefully

Description (last modified by SergeyBiryukov)

The class WP_Widget in wp-includes/widget.php makes use of PHP4-style constructor for compatibility with plugins (mostly).

I propose two changes here:

  • A direct call to the old constructor should trigger a deprecation notice
  • The PHP4-style constructor *must* be declared after __construct() otherwise, an E_STRICT regarding constructor re-declaration is thrown.

Please find a patch attached...

These changes look similar to the ones I have in my patched wordpress. That fixes the E_STRICT error for me, too. I attach my changes merged with yours, I think this needs to be deprecated with the next point release (3.4.0).

Thank you for bringing that issue up, this change went a bit lost on my box.

This is a related test-case:

Cool - temporary I do the patch on my local latest 3.6 nighty built...( moving ph4 call after constructor ) - no annoying message from widget.php. (I also take opportunity to upgrade my oldest plugins using WP_Widget class) - Waiting the next 3.6 nighty built ;-)

Not sure I see the reason for deprecating right now. Fixing the E_STRICT sounds good.

20801.3.diff swaps the order of the constructors to avoid the E_STRICT notice, but doesn't deprecate the PHP4 one.

Of note, PHP 7 is considering the removal of the old style constructor
