How can I customize wp_footer, where is the code that controls what this function does?

This could be multiple things. I’m not sure what the credits do. However, the chance is quite big that the search field is being created by a widget, shown in the get_sidebar(‘main’). Under “Appearance” > “Widgets”, you should be able to find more information. The template being called is probably sidebar-main.php. If it is a … Read more

SQL query to get adjacent posts from search query

Although this is possible, it really is not viable. I’ve done a lot of research on this subject, but could not find a straight forward answer I went and had a look at the WP_Query class for a possible solution, and I came to the conclusion that what I was trying to accomplish would not … Read more

multiple search forms and search results

If you only want to search a particular post type include a hidden field with the name post_type and the value set as the name of the post type you want to search: <form role=”search” method=”get” action=”https://wordpress.stackexchange.com/”> <input type=”text” name=”s” placeholder=”Search”> <input type=”hidden” name=”post_type” value=”post_type_name”> <input type=”submit” value=”Go”> </form> Just replace post_type_name with the actual … Read more
