I want to add meta fields for the sites in my network (such as a thumbnail and a category). I know how to do this using get/add/update_site_option, but I'm wondering where I could put the UI to manage those meta fields.

The best place would be in the Sites > Infos page, just after the site attributes, but I can't find any hook to hang on. I can add those fields in the "Settings" tab of the same screen, but one has to scroll down a lot to find it, and it gets mixed with advanced settings.

Any suggestion ?

I finally found a way to add more lines to the Sites > Infos table : My own option in the Sites > Infos table

It's a little bit ugly, but it works. I simply use the action admin_footer to add a bunch of HTML code at the end of the page, and then use jQuery to move it to the right place.

add_action('admin_footer', 'user16975_custom_options');
function user16975_custom_options(){
    global $pagenow;
    if( 'site-info.php' == $pagenow ) {
        ?><table><tr id="user16975_custom_options">
            <th scope="row">My own option</th>
            <td><input type="text"/></td>
            $('.form-table tbody').append($('#user16975_custom_options'));

The good part is that as soon as the hook will be available, I can use it without big changes in my code.

    It's simpler with global $pagenow; if( 'site-info.php' == $pagenow ) {}. . . . For the records, I just saw that Multilingual Press creates a new tab in that screen.

  • Thanks for the $pagenow tip @brasofilo, it's cleaner. Commented Jul 7, 2013 at 20:27
  • Multilingual Press is using the manage_sites_custom_column action to add a column to the sites table in sites.php page. I want to add a tab in the site-info.php page, where you can change the informations linked to one of the sites. Commented Jul 7, 2013 at 20:29
  • MLP has a tab in site-info.php, but I just checked and is injected with jQuery as well :/

    How would you save the data along with the other fields on submit?

First off all – I agreed, there is no specific hooks in this part of the core that allows to create custom setting fields there. But anyway it is possible.

WordPress has network_edit_site_nav_links filter hook which allows to create your custom tab.

But no hooks for the page for the new tab, but it is not a problem anyway because you can achieve the result with simple options page and a little CSS code.

In this tutorial everything is described by steps https://rudrastyh.com/wordpress-multisite/custom-tabs-with-options.html (I think it is no reason to copy all the code from there to this thread).

    This is a great answer, but you should update your answer include the code here. We don't know how long your site will be around. Commented Feb 14, 2019 at 23:50

    😊 thank you! Actually I do not know how long my stackoverflow profile will be around. I received a warning a couple weeks ago. As for my site – it will be around as long as I am alive at least :) Commented Dec 23, 2022 at 9:14

The Site Info admin page's code is here: http://core.trac.wordpress.org/browser/trunk/wp-admin/network/site-info.php

Unfortunately, there don't appear to be any hooks or filters in the site-info.php code.

It looks like you'll have to make your own administrative page -- perhaps in the wp-admin Settings menu -- to handle your {$verb}_site_option code.

  • I want to have my options UI in the multisite administration zone, (wp-admin/network/...), not in each individual site dashboard. For example, that would be great to have the possibility to add a tab in the Sites > Infos page. Commented Jun 21, 2013 at 13:40
  • This might be what you're looking for then -- wordpress.stackexchange.com/questions/16474/… -- from the Related links on the right.

  • Nope. The post you are linking is talking about the Settings main menu in the Network admin dashbord (wp-admin/network/settings). I'm talking about the page where you can modify individual site options in the Site main menu (wp-admin/network/site-info.php?id=X). Commented Jun 23, 2013 at 20:46
  • You might be out of luck, then.
