Yes, get_site_option() is for data about the whole network. The irritation comes from a mixed vocabulary: what was a site once is a network nowadays, and what was a blog once is now a site in a network. wp_get_sites() for example is from version 3.7, it fetches sites in a network, not all networks in … Read more
If a user can not change them then they are not options, they are constants. Declare them using const in your maim theme file (probably functions.php but any other files that is being always loaded will do), and use them wherever you have use the “options” array now. If you want to control it without … Read more
I dont know if it is possible to add a new field directly under the “Posts page” dropdown field, atleast I found no way to do this. But you could just add another dropdown menu to the reading settings page. This will be on the bottom thou. To do this, first we need to register … Read more
The why part can be found in ticket #24889. Let me quote @azaozz: When support for multi-use widgets was introduced, a lot of widgets got converted from “single” to “multi” at the same time. To keep backward compatibility and not break the existing widgets, there was some conversion code that would set the “single” widgets … Read more
You’re absolutely right that you can pass reusable form field markup to add_settings_field(). The trick is to define the data type for each setting, and then pass the same callback to each call to add_settings_field(). Within that callback, you simply add a switch that includes cases for each data type. Here’s how I do it … Read more
I’ve answered a similar Question. Basically: create a Dropin plugin at the root of wp-content named install.php inside install.php, create a new version of the pluggable function wp_install_defaults() remove all unwanted defaults and customize at will, like: update_option(‘template’, ‘your-theme’); update_option(‘stylesheet’, ‘your-theme’); update_option(‘current_theme’, ‘Your Theme’); update_option(‘my_theme_options’, $theme_options_array ); auto-activate some bundled plugins bundle everything into one … Read more
Both ways are almost equal, the first will be slightly faster, because the callback is called only if the check equals to TRUE. Note you cannot test an option like this, unless the option name is really ‘my_option[option_1]’. What you probably want is: if ( $test = get_option(‘my_option’) and 1 === $test[‘option_1’] ) add_action(); An … Read more
Quite personally I disagree with the author of the book to an extent. If you are auto-loading multiple options in your database when WordPress is initialising it’s doing a lookup that looks like this: *”SELECT option_name, option_value FROM wp_options WHERE autoload = ‘yes’”* — at the beginning. Now, imagine if you had 40 options, that’s … Read more
Try esc_html( $string ) (Codex ref), which among other things encodes single- and double-quotes. For further reference, see the Data Validation entry in the Codex.
Thanks to a tip from milo in the comments above, I looked at this similar question. There is an answer provided by Laurent which basically gets the option using wp-cli, pipes it to an inline php program, makes the adjustments and then pipes it back to wp-cli. I took that idea and generalized it somewhat … Read more
