How to search for value “null”?

mugwumpr — Tue, 03 Nov 2020 00:43:17 +0000

Hello,

I have a field for the Google Category number. Some products have it and some don’t. Those that don’t show “null” in that column.

I want to find only those products that don’t already have a value in that column.

Whenever I try a search on that column, I get no results.

It wants to search it numerically (==, !=, <,>, etc.). I’ve tried ==0, <0, and !=2169 (the GC for Mugs), but I get an empty result set for all of them.

Thanks!

Multiple post types – blank output (pip-not-found)

Hi, I’m trying to configure your plugin with multiple post types and my result is empty output with pip-not-found span class inside ivycat div.

WordPress 4.8 + twentysixteen theme.

Tried with both CPT UI plugin as well as manually added post types, result is the same.
Placing shortcode as described in usage page. My shortcode is:

[ic_add_posts showposts='5' post_type='post,komunikat' template='homepost-template.php']

Templating works fine. When I use only one post type, each is displayed correctly. Any custom post type slug added in shortcode, breaks it.

Unfortunately I cannot share my installation access because my blog is for intranet use only, without access from WAN.

I’d be greatful for any hints.

Get custom post gives empty array ?!

I implemented the WP REST API Controller and I see and can configure a bunch of custom posts and get reliable results.
BUT one of it delivers just an empty JSON array [] even if there are custom posts containing content?!

TIA for any hint

[Plugin: WP Attachment Export] Attachments export returns an empty file

Vladimir Vassilev — Thu, 30 Aug 2012 19:34:39 +0000

After installation I try to get all attachments, but it returns an empty file after a bit of waiting (like half a minute).

It might be because I’ve got about 10 000 posts and each has at least one attachment… I dunno.

get_posts() doesn’t work when category is specified

zimmi88 — Sun, 29 Mar 2009 01:58:01 +0000

Hi! I’m currently working on a plugin that will manage custom output for the homepage of a site I’m constructing. Unfortunately, I’m having problems with the get_posts() function.

What I would like the code to do is loop through the categories, printing out the posts that are associated with each category and has a specific tag, as specified in the settings. However, as of now, if I specify a ‘category’ in my get_posts() query, I get back no posts. If the ‘category’ option is omitted, the function works as expected (outputs all posts with specific tag in specified order).

I’ve tried placing my options in an array and query string. I’ve tried ‘category_name’ instead of ‘category’. Finally, I’ve tried being extremely explicit with typecasting. Sadly, all of these haven’t done anything.

I’ve pasted the source at https://new.pastebin.ca/1375334.

Any help anyone can provide in this matter is greatly appreciated. Thank you in advance for your help!
