The wpseo_opengraph_image filter can only be used to modify the existing og:image. Otherwise, you will need to hook into the wpseo_opengraph action to add a different image. Here’s an example of adding an image from a custom field on the post object (assuming you’re using ACF here). function my_wpseo_opengraph() { global $post; if (isset($post)) { … Read more
As far as I remember the users in multisite are shared. They are tracked in one database table and use same cookie for authentication. The more practical approach is to track not merely login status, but capabilities. Users should be exposed to actions/information that they can perform/see, according to their Role on specific site. You … Read more
It is a fact of life that you will have to deal with some spam on any site. There are other ways of combating spam: such as a Q&A Captcha (the site asks the user a question such as “What is the name of the site?” and the user has to answer it correctly: very … Read more
I began using Multisite just a few months ago, and am really loving it. You’re going to want to use the sub-domain structure if you have a host that supports it. I use a Media Temple Grid Server plan. It will allow you to create a subdomain and then mask it with a symbolic link. … Read more
I always develop the webiste locally on my machine with the setup mydomain.dev and using svn or git to save versions of the code. The next step is to put it on a test domain like stage.mydomain.com and after that mydomain.com I use this to change the url:s in the database: https://interconnectit.com/products/search-and-replace-for-wordpress-databases/ Its a search … Read more
In WordPress you can easily do this with sub-directories like example.com/user1 Sub-domain & URL Strategy Having username.domain.com will prevent you in the future from having your own sub-domains like shop.example.com and will plague you if you wanted to use www.example.com or just http://example.com Finally … what if some user wants to use expletives or special … Read more
You can do this by adding some code to wp-config.php $request_uri = $_SERVER[‘REQUEST_URI’]; $debug_dirs = array (‘/debug-dir1/’,’/debug-dir2/’); // list of directories to turn on debugging foreach ($debug_dirs as $debug_dir) { if (!strncmp($request_uri,$debug_dir,strlen($debug_dir))) { define(‘WP_DEBUG’, true); } } define(‘WP_DEBUG’, false); // debug off by default
If you installed WordPress Multisite starting with version 3.0 to 3.4.2, you’ve got the correct .htaccess file contents. However, if you started with a newer version (3.5 or higher)—and I’m assuming you did, if you’ve just installed WordPress Multisite recently—your .htaccess file should look like this: RewriteEngine On RewriteBase / RewriteRule ^index\.php$ – [L] # … Read more
Use the defines to make it pick the site you want it to pick. You can define these four to setup the $current_site values properly: DOMAIN_CURRENT_SITE, PATH_CURRENT_SITE, SITE_ID_CURRENT_SITE, BLOG_ID_CURRENT_SITE. If you check the wpmu_current_site() function in ms-load.php, you’ll see that it uses those to create the $current_site global. You may or may not have to … Read more
I would suggest you take a look at WP Dummy Content. You can easily extend this plugin or build a script to activate and run it. As suggested by @kaiser I would really record all the performance data I can to get in insights into this scale of operations.
