Follow-up: Variable layout_info is now null in preprocessors

[indigoxela]

Description of the bug

Having a theme, that relies on $variables['layout_info'] being available and contain values.

Update to BackdropCMS 1.34.x and inspect log

Actual behavior

Warning: Trying to access array offset on value of type null in THEME_preprocess_layout__XXX() (... themes/YOURTHEME/template.php).

Expected behavior

Values available as before 1.34.x, I guess. No need to update themes.

Additional information

• Backdrop CMS version: 1.34.x

Introduced with Issue #6808: Allow to specify a layout template type.

The variable still exists, but is NULL now, so one can no longer access keys like name

Yes, that value is deprecated but not slated to be removed until Backdrop 2.0. From layout_preprocess_layout():

// Support deprecated 'layout_info' property until Backdrop 2.0.

[indigoxela]

Yes, that value is deprecated

I saw that, but wasn't aware, that the variable is now just NULL, no longer an array of values.

[laryn]

Correct, it should still contain the values that it had previously until Backdrop 2.0.

Oh, a PR, and oh, such a simple solution. 😆

I tested with a theme that implements hook_preprocess_layout (actually hook_preprocess_HOOK), and can confirm that this simple trick fixes the NULL var problem. Both variables, provide the same info array. Works for me! 👍
