Tags to categories importer

Misc thoughts. Convert category to tag by setting the type bitfield to TAXONOMY_TAG unless the category is also a link category (link_count > 0). In that case, bitwise or TAXONOMY_TAG into the bitfield. Change rel_type in post2cat from category to tag for all posts with that category id. Copy count to tag_count and then zero out count. Link to the importer from Manage->Categories for better discoverability.

Okay, that's about 80% done. Just the bitwise stuff and count adjustments that need to be made. If you could post some examples of the bitwise stuff, that'd be great. I'm completely ignorant of bitwise functions :\.

I'll tackle the rest tomorrow morning, PST.

v3

(In [5201]) Add initial category to tag importing. see #4107

Todo: Add call to clean_category_cache(). Link to converter from Manage->Categories.

(In [5203]) Add clean_category_cache() and capability checking. see #4107

I think the initial work is pretty much done. We can open other tickets in reference to this one, or just reopen this.

To do -- link to converter.

(In [5216]) Link to categories to tags converter and UTW importer. fixes #4100 #4107

I get the "cheatin' uh?" error when I go to use this. Doing a little googling, it seems I may have some permission issues causing that error but everything looks okay.

3 1 gNYC_capabilities a:1:{s:13:"administrator";b:1;} I'm also using a custom table prefix (gNYC_ instead of wp_), and I put my wp_cat2tags.php file in wp-admin

I'm running the nightly 2.2-bleeding from 4/9/2007

P.S. - This is my first bug here, so please let me know if I can provide more info or if this is the wrong place for this issue.

Thanks Eric Skiff

Confirmed issue and I'm not using any custom permissions plugin.

This may be because I checked for current_user_can('manage_tags') -- not sure if that's set up.

Yep. Took that out and worked for me.

(In [5218]) Just check for manage_categories. fixes #4107

Every time I run this it gives me this error, for every category:

Converting category #79... Category doesn't exist!

It also seems to list tags in the checkbox thing, where it should really only lists categories.

Replying to matt:

Every time I run this it gives me this error, for every category: Converting category #79... Category doesn't exist!

I *think* this is because apparently category_exists return the category ID on success, and also it takes the nicename. I'll add in a function local to the importer class that checks based on ID, and returns either boolean true or false.

It also seems to list tags in the checkbox thing, where it should really only lists categories.

This is just my stupid mistake :\.

(In [5229]) Use own category_exists() function, and only list categories to convert. fixes #4107
