Wordpress additional fields - wordpress

In my WP installation I have a category called "books". In addition to the title and body text I'd like to add a field called "ISBN" that must be filled in for every post in this category. In the Blog category this field should not be displayed in the admin.
In Expression Engine and Drupal it's quite straightforward to add fields like this but I'm not sure about how this works in WP. What's the best way of doing this in WP 3.2.1?

In wordpress this can be done by adding meta-data to posts

How can I use an acf_form() submission to also update my post title and permalink?

I have a WordPress site and I am using acf_form() to allow users to update ACF fields of a custom post type (this part is working fine). But I also want the post title and permalink to change based on a particular ACF field. How can I accomplish this?

How can I change a wordpress custom post back to a standard post?

I have inherited a legacy wordpress installation which has a complex template with a couple of custom post types.
I want to migrate it to a simpler theme and convert all the custom post types back to regular posts.
I have gone into the wp_posts table and changed the values in the post_type column from "product" or "service" or whatever back to "post" and the posts in question now load into the template, but they don't show up in the list of posts in the admin page. If I load the editor on another post, and change the ID in the url bar to one of my would-be normal posts, they will load up and I can edit them, but I just can't make them show up in the posts list.
Is there somewhere else I need to change things to make Wordpress see them as standard posts?

Wordpress - Show parent category AND subcategory name in subcategory archive URL

I'm having some trouble with Wordpress category/subcategory archive URLs.
For example, I want to be able to display this archive: http://faroutmagazine.co.uk/wp/track-of-the-day while keeping its parent category in the URL, making it http://faroutmagazine.co.uk/wp/music/track-of-the-day
Previously, I was just getting a "This is embarrassing..." 404 message when accessing the /music/track-of-the-day URL (even though that's the one that was appearing in the View option under categories in the admin section of WP).
Now the View link in the admin area only shows me the /track-of-the-day URL, and this DOES display the category posts which is great, but I want it to include the parent category in the URL.
Is there anything I can do to the functions.php file or any plugins I can add to make this happen? Please bear in mind that there are multiple subcategory archives on this site, and they should all contain the parent category in the URL.
***UPDATE:
I actually have just set everything up a different way now using Pages and showing category archives on pages as it's taking up too much time. Thanks for your answer though. People telling me to use %category%/%postname% as the permalink structure are incorrect - yes, this works for the POST urls but not for the archive category of the subcategory which is the problem I was actually looking for help with. If anyone can provide an answer, it would be appreciated, but I am using this workaround now as this was taking up way too much time trying to figure out.
This happens because you chose category and subcategory from the right options tick boxes when editing the entry. Choose only the subcategory box in every entry and it will show the nested URL.
To make this happen you need to make some change in permalinks
go to Settings->Permalinks then select custom structure and use this syntax " /%category%/%postname%/ "in the field
Now save the settings and you can see the post url's using its category name in the permalink
Hope it helps :)
You should set hierarchical value to true when you are defining your taxonomy.
'rewrite' => array('slug' => 'mySlug', 'hierarchical' => true),
Then if you have a subcategory the url will be shown like this:
http://example.com/taxonomy/parentCategory/subCategory/
I found this sloution here:
https://wordpress.stackexchange.com/questions/155319/how-to-include-parent-terms-in-hierarchical-taxonomy-urls
Actually hierarchical subcategory archive permalinks are default in wordpress.
If you have a "pretty permalinks" structure selected in settings > permalinks, like /%postname% for example, then category and subcategory archive urls should default to something like:
yourdomain.com/category-base/category/sub-category/sub-sub-category
I had encountered a similar issue with a recent WP project, BUT I was using a plugin called WP No Base Permalink in order to get rid of my category and tag base slugs in my archive permalinks. When I deactivated the plugin, category hierarchy suddenly returned to my archive permalinks (luckily this project was still in development, otherwise, I would have had some major 404 problems).
I have not yet found/tested another plugin for eliminating category/tag base slugs that will also preserve hierarchy in sub/category archive urls, but it turns out that I do not need that functionality for my current project.
Instead I am using the base slugs blog-articles and blog-tags for the standard categories and tags in order to set the blog taxonomies apart from other taxonomies. Then I am using the plugin Types to create a custom post type and custom taxonomies for that post type. The Types plugin has an option in the advanced settings to set hierarchical taxonomy urls to true or false when creating a custom taxonomy.
Finally, I found a plugin called Remove Taxonomy Base Slug that effectively eliminates the default taxonomy term from the base slug of the taxonomy archive urls. And this, thankfully, does not interfere with the hierarchical sub/category urls, OR the base slugs for standard tags and categories.
So now, my blog categories/tags look like this:
yourdomain.com/blog-articles/category/sub-category/
or yourdomain.com/blog-tags/tag/
And my custom post type categories/tags look like this:
yourdomain.com/category/sub-category/ or yourdomain.com/tag/
Phew!
I hope this helps!
Setting Settings->Permalinks->Category base to '%category%' should give you what you want. According to WP doc:
Nested sub-categories appear as nested directories in the URI
See http://codex.wordpress.org/Using_Permalinks.
The Permalinks settings should be like /%category%/%postname%/ ..
If use custom permalinks settings as %postname% only, it will make your url in the form of .../category/subcategory.
You can use WordPress plugin to remove 'category' from url
http://wordpress.org/plugins/wp-no-category-base/
and then follow the instruction given by Maruti

Wordpress custom post type page

When creating a custom post type and fill it with some posts wordpress generates a page for that custom post type.
But I want to be able to add content to that page so I create a regular page and choose a template where I manually call the custom post type posts and loop them out. And now I can just add content in the wysiwyg editor. But this causes a conflict between these two pages, especially if the CPT has the same name as the page.
And now the question: Is there a way to always show the page where I have chosen the template for the CPT to always show? Even when someone try's to manually enter the url for the CPT generated page?
Here is what I understood from your question. You have custom post type. Then you created a page-template, that loops through your custom post types and output them. Now when you create a new page and assign it the page-template you have created you run into problems, if it has the same name as the custom post type.
Solution: I think what you need to do is change the custom-page slug from the admin menu. Then you would be able to directly reference it by the URL.

Wordpress: add a custom field option that's available to all posts

As part of my theme install, I'd like to add a set of custom field options to the wordpress database that would be available to all posts as long as my theme is active.
For example, I'd like to add these fields:
custom-image-1
custom-image-2
custom-image-3
And also these
custom-image-1-link
custom-image-2-link
custom-image-3-link
And then when a user goes to add or edit a post, they can insert values for each of these fields if they choose to...
You simply have to create a post and add these custom fields once to have them proposed for every next posts (in the custom fields part of the form).
If you need to create a more integrated interface for these extra fields, you might be better off creating a plugin or looking for existing ones, such as this one.
Use the add_meta_box function that comes with WordPress.
