You probably need to write some custom php ir javascript within a child theme to be sure your customizing sticks for the specific category.
More on child themes: https://developer.ww.wp.xz.cn/themes/advanced-topics/child-themes/
The code you posted simply outputs the current post within a loop. It’s likely within code that actually drives the loop. Which posts are looped through depend upon the query made. You may query for posts in multiple categories, but the list will not be sorted by category, that’s not a possible option with the usual WP_Query class. Ordering posts by category would require a custom query or custom PHP code to re-sort the posts. Pagination is difficult and inefficient with the sort with PHP option if there are a lot of posts in the query results.
Another possibility would be to make individual queries for posts in each category, making a separate loop for each. The same output code could be reused by nesting loops. If you have a lot of categories to query for this will not be a very efficient option. Preventing duplicate listing of posts which have multiple terms might be something you’d want to address as well. This approach can also be difficult.
The easiest solution is to simply list category terms, each term linking to an archive page for that specific category term.
Like Davood said, any of these can be implemented through a child theme.
Hi pros,
That’s a example code only. I just want to define this code by a function or script…, then I can call it when show a list of any category. Because I don’t want to write the page with very long code but same.
It’s possible? How to do it?
Thank you.
I think I understand now, sorry for my misunderstanding earlier.
One approach would be to simply wrap it in a function declaration. For example
<?php
function do_my_thing() { ?>
<!-- your code goes here -->
<?php } ?>
Where ever you want the code to execute, call the function:
<?php do_my_thing(); ?>
Function declarations are normally done on a theme’s functions.php or a plugin file. You do have to mind variable scope within functions. Any variables are local to the function. As long as the other functions called within this function are working off the global $post object, as they appear to be, all will be fine.
As this appears to be template code, there’s a more “WordPressy” option. You could place your code in its own template file. Then call this partial template with get_template_part(). The parameters for this are a little odd. Let’s say your template file is in the file templates/page-category.php, relative to the main theme folder. On another template file, you’d include this one with:
get_template_part('templates/page', 'category');
The template part code always concatenates the joining '-' and terminal '.php', so do not include these in your parameters.
A reminder: when dealing with custom templates and code, it’s best to create a child theme to contain your work. get_template_part() only works for themes (including child themes), don’t try to use it to load plugin code that might be in template form.
