I want to create a subpage, e.g. /test/ and everything that I enter after /test/ should have one specific template and indexing, no 404 error.
I wanted to make this with virtual pages, but it's too many url's to add. (tried here - Wordpress fake/virtual folder)
I've got my template page-pagename.php which works. Now I need to add that every child of test does not return 404.
I think I have already searched the entire internet and cannot find a solution to this task
What you could fiddle with is with grabbing the main query on 'template_include'. You add an action like this. You can add it to your child theme in functions or in your custom plugin.
add_action( 'template_include', 'custom_router' );
Then in the custom router function, you can check the parameters that you are requesting ('test') and redirect to a template of your choice. Also add in functions.php or in custom plugin. Place a template file in the relevant path.
function custom_router( $query ) {
global $wp_query;
if($wp_query->query['name'] == 'test') :
var_dump($wp_query->query['name']);
var_dump($wp_query->query['page']);
return dirname( __FILE__ ) . '/some-template.php';
endif;
}
I tested the code in the latest wordpress version with a custom plugin and the default theme btw.

I'm relatively new to working with WP. In my main plugin file, I have a couple of hooks working. I have another file that I'm trying to add an add_action() to, but it keeps coming back as undefined.
What are the basic requirements for a file to hook into WP?
add_action('init', 'loop_users');
function loop_users() {
$users = get_users();
//execute code here
}
When i use this add_action or any other WP hook it always returns as undefined. Thoughts?
You can include your other files to your main plugin file using include statement. For example if your main plugin file and another file are in the same directory.
include dirname( __FILE__ ) .'/yourfile';
I have a fresh WordPress and bbPress installed on an internal server.
While I was setting up bbPress I wanted to test the functionalities like creating a forum, topic, etc. When doing these stuff in the back-end (dashboard) there didn't seem to be any problems but when I did it from the front-end I kept getting
ERROR: Are you sure you wanted to do that?
I searched for a solution and found this.
add_filter( 'bbp_verify_nonce_request_url', 'my_bbp_verify_nonce_request_url', 999, 1 );
function my_bbp_verify_nonce_request_url( $requested_url )
{
return 'http://localhost:8888' . $_SERVER['REQUEST_URI'];
}
I simply changed the hard-coded URL to what our internal server is set up to and it fixed the problem.
Now my question: is it possible for me to add this solution to a functions.php that is independent of the theme being used? I asked this because I have 2 concerns:
The current theme might get updated and will overwrite the file
I'm aware that the solution to this is simply create a child theme but my second concern prevents me from doing this.
The WordPress administrator might change themes and so both the functions.php file on the main theme and the child theme will stop working
How could I add the solution above so that I don't have to worry about the theme being updated and/or replaced with a new theme in the future? I don't want to keep adding this solution every time the administrator decides to change themes.
If you can't put it in a theme, put it in a Plugin. If you're worried that the plugin will get de-activated make it a Must Use Plugin.
It's dead simple to create a plugin. Create a file plugin-name.php and place it in a directory wp-content/plugins/plugin-name/. That file should contain the following code:
<?php
/*
Plugin Name: Name Of The Plugin
Plugin URI: http://URI_Of_Page_Describing_Plugin_and_Updates
Description: A brief description of the Plugin.
Version: The Plugin's Version Number, e.g.: 1.0
Author: Name Of The Plugin Author
Author URI: http://URI_Of_The_Plugin_Author
License: A "Slug" license name e.g. GPL2
*/
add_filter( 'bbp_verify_nonce_request_url', 'my_bbp_verify_nonce_request_url', 999, 1 );
function my_bbp_verify_nonce_request_url( $requested_url )
{
return 'http://localhost:8888' . $_SERVER['REQUEST_URI'];
}
If you want it to be a must use plugin, put it in wp-content/mu-plugins/ instead of wp-content/plugins.
I have this in my index.php file. It adds the home banner image in WordPress. I know that it is mostly generated in WordPress customizer, but I need to add an anchor tag in this section. I can't find it anywhere in the file structure.
<?php do_action('cleanblog_index_top'); ?>
I'm not able to find where cleanblog_index_top leads to. Any help would be great. Thank you!
I stumbled on this old one while looking up the docs for do_action(). The answers are brutal so I decided to provide a better answer in case anyone else stumbles here.
If a WordPress theme has something like do_action( 'example_action_hook_tag' ) somewhere in one of the template files (such as index.php, page.php or whatever) the purpose is to provide theme or plugin authors with a way to write their own custom function that they can then "hook" onto the action with the function add_action().
WordPress would then call this function any time and anywhere do_action( 'example_action_hook_tag' ) is called.
The creators of commercial themes will often litter their template files with hooks declared with do_action() to make it easier for their customers to customize their themes via functions.php or by writing a site-specific plugin.
It looks to me that this is the likely scenario that is impacting the OP. This also explains why the OP was unsuccessful in finding where this "leads to".
It would only "lead somewhere" if the OP wrote a function in the theme/child-theme functions.php or in a plugin and added the line do_action( 'cleanblog_index_top', 'name_of_ops_function' ) to hook their function onto the cleanblog_index_top. WordPress would then call their function when do_action( 'cleanblog_index_top' ) was called in index.php.
From the name of the OP's hook, cleanblog_index_top, it sounds like the theme author intended to provide a way for others to inject output at the top of the index page template.
Suppose the OP wanted <h1>Hello World</h1> to appear there.
In functions.php of a theme/child-theme the OP could add a function that echo's this out:
function op_customization() {
echo '<h1>Hello World</h1>';
}
And hook their function onto cleanblog_index_top:
add_action( 'cleanblog_index_top', 'op_customization' );
Cheers!
You should never edit the index.php file directly, for the same reason you should never edit core Wordpress files directly - the next time WP pushes an update, your changes will be overwritten (and that assumes you don't break anything). Never edit plugin files directly, same reason.
You need to look in your theme, you should only make changes to the functions.php and style.css files in your theme - unless you create a child theme and that is a topic you should Google.
I have a specific page on my wordpress website example.com/download/ that I already have a page for. I would like to add some sort of php code to enable the following functionality.
If there is a subpath after the /download/<name>, I would like to fetch a file from some directory based on <name>
If no subpath is specified (/download/) I want to display the page that is already written
Is this possible with Wordpress hooks/filters?
I have a feeling it has something to do with the WP_Rewrite class, but I am not sure exactly what to write, nor where to put it without WP or theme updates wiping the code
Yes, you have to add a custom rewrite rule. You can use your theme's functions.php to add the new functionality.
function custom_rewrite_rule() {
add_rewrite_rule('^download\/([^/]+)\/?','your_url_to_the_downloader_file.php?download=$matches[1]','top');
}
add_action('init', 'custom_rewrite_rule', 10, 0);
To make it work, first you need to go to Admin -> Settings -> Permalinks and click the save button so the new rule is added.
I'm at an early stage of learning Wordpress (and shortcode), so bear with me:
To me, shortcodes seem like a swiss army knife of not having to use page-specific templates for everything. I like to build as many pages in the wysiwyg as possible, but often I would need some (reusable) php stuff for displaying stuff in a certain way.
Having googled a lot, it seems to me the way to do shortcodes is like:
function caption_shortcode( $atts, $content = null ) {
return '<span class="caption">' . $content . '</span>';
}
My question is, is it possible to put the html in a separate template-ish file? It seems wrong and verbose to put all this markup here, escape quotes, et.c. Like a template-file for a shortcode, to which the shortcode can pass some Data Transfer Object (or simply just some scoped variables). So: display in template-file, logic for finding data (to pass to said template-file) in shortcode-function (wherever it may be defined, functions.php, separate plugin, or something).
You can set-up views(php files) and then include partial views into those ones. Wordpress allows templates to be includes within other templates to ensure code reuse and its easily modifiable by child themes. You can use this function to include those
get_template_part( $slug );
However, in your case, the short code function needs to return the value to the caller function. So, this setup will not work.
For code that effects FUNCTIONALITY, put your code in a plugin.
For APPEARANCE, put your code in your theme's template files or funtions.php file.
Many beggining WP developers lump all their code into the theme's functions.php file, this is often the wrong place for it (if that code might ever get exported to another theme, for instance). Only put code specific to a specific theme in a theme's functions.php .
To get Wordpress to recognize your plugin, create a php file and start the file like this:
<?php
/*
Plugin Name: My Caption Shortcode Plugin
Description: A really cool plugin
*/
function caption_shortcode( $atts, $content = null ) {
return '<span class="caption">' . $content . '</span>';
}
?>
Put this file in your plugins directory (usually, you should create a sub directory for each plugin). Plugins are usually held in /wp-content/plugins/ . Then you can activate or deactive the code as a plugin, when you go to the plugins tab in the admin menu.
Of course, this plugin won't do anything as is. Remember that plugin functionality should be hooked into Wordpress via action hooks, filters, and shortcodes. For a shortcode for instance, you'd use the function add_shortcode somewhere to let Wordpress know your function is a shortcode.
