PHP notices for WordPress 2.8

[Viper007Bond]

Been catching a lot of PHP notices lately and rather than making a ton of more tickets, I figured one per milestone would be better.

So here's one for 2.8. Feel free to attach patches of your own to this ticket.

Other notice tickets: #9292 #9309 #9333 #9336 #9365 #9366 #9367 #9369 #9370 #9392 (plus more probably)

[nbachiyski]

Deleting a widget, which is beng used generates non-existing array key notices

[nbachiyski]

Sometimes the sticky option has value of 'Array'. It has been fixed, but until changing it I get the notices. Another check won't harm.

[nbachiyski]

Two more tiny notice patches.

[sivel]

If there are no widgets don't try looping through them

Todo:

• 9393-registration.diff - need to spend a little time understanding issue
• 9393-widgets-var-notice.diff - no longer applies
• template.diff - need more detail to understand issue.

[sivel]

Perhaps a better way to handle 9393-registration.diff is to instead of excluding ID of the user being updated created is to use the user_login.

When creating a user the users ID does not exist and is of course not in the database yet. So a notice is thrown reporting that $ID is undefined. Instead of using ID perhaps user_login would be better.

template.diff - need more detail to understand issue

The patch changes the call to the_author_ID which otherwise on current trunk produces PHP Notice: the_author_ID is deprecated since version 2.8! on the edit posts screen.

[sivel]

Replaces template.diff as this fixes the notice in 2 locations where as the other missed one

[sivel]

Apologies on the file extension for that last one. I don't know what I was thinking.

[automattor]

(In [11322]) Use the_author_meta(). Props sivel. see #9393

[mrmist]

Uses get_the_author_meta instead of get_author_name()

[mrmist]

Added patch for post_template to use get_the_author_meta ('display_name') instead of deprecated get_author_name function, fixes notice shown on publishing new posts.

[ryan]

(In [11331]) Use user_login instead of ID to check if user exists when creating unique nicenames. ID isn't available when inserting new users. Props sivel. see #9393

[sivel]

This patch replaces post_template.patch. Replaces get_author_name in all locations in which it is used

[sivel]

Accidental attachment of incorrect patch. Ignore the previous attachment.

[sivel]

This patch replaces post_template.patch. Replaces get_author_name in all locations in which it is used

[westi]

(In [11370]) Migrate final get_author_name() calls to use get_the_author_meta() instead. See #9393 props sivel.

[Viper007Bond]

current_theme_info() is still throwing notices.

[scribu]

Also getting a notice while trying to add a category in edit.php (rev. 11372):

Notice: Trying to get property of non-object in /home/cristi/svn/wp/wp-includes/category-template.php on line 91

[sivel]

Last round of replacements for deprecated get_the_author_* and the_author_* functions.

[ryan]

(In [11416]) Use get_the_author_meta(). Props sivel. see #9393

[mrmist]

When DB Cache plugin is active, WP shows following warning many times:

Notice: Undefined index: debug in C:\wordpress28.local\wp-content\db.php on line 646

I am not sure if this is a WP or plugin issue. I am using WP 2.8 beta 2.

[dd32]

When DB Cache plugin is active, WP shows following warning many times:

Thats a issue in the DB Cache plugin, not WordPress.

Its probably got code such as this:

if ( $this->options['debug'] ) {
...

Which is wrong, Really, it should be written like this:

if ( isset($this->options['debug']) && $this->options['debug'] ) {
or just
if ( !empty($this->options['debug']) ) {
