at the moment I am working on a Wordpress theme with a functions.php that will include multiple helper functions files. I want this theme to be very flexible and customizable if a child theme is made based on the theme.
I have this piece of code currently in my functions.php:
add_action( 'template_redirect', 'wpf_contact' );
/**
* Include the logic/settings for tpl-contact.php.
*
* Includes the logic/settings for tpl-contact.php. It will load the child's
* mail.inc.php first if that is available.
*/
if ( ! function_exists( 'wpf_contact' ) ) {
function wpf_contact() {
if ( is_page_template( 'tpl-contact.php' ) && is_child_theme() && file_exists( get_stylesheet_directory() . '/inc/wpf/mail.inc.php' ) ) {
include( get_stylesheet_directory() . '/inc/wpf/mail.inc.php' );
} else {
include( get_template_directory() . '/inc/wpf/mail.inc.php');
}
} // end wpf_contact()
}
What the code above does is load mail.inc.php from child if the files exist. If it doesn't load it from the parent theme.
Cause I am having multiple files I want to load like that. I was thinking it there might not be a easier way of doing this? Is there a built in function that does this in WordPress?
Or should I just adjust the above function and add parameter's so it can be used for other files as well? Not sure if this is efficient.
To answer your question directly based on your sample, i would not check to see if the file has been placed in the child theme. If a child-theme developer has customized the file, they can simply declare the function and include their own file (wherever they place it). There is no risk of code duplication because your sample function is simple enough.
Even if you simplified your code for the purposes of placing it here....you can always keep includes wrapped in a very simple function that can be declared by a child theme. This will keep PHP running efficient and not having to check for files all the time.

I working on my plugin and tried to override some templates.
If I visit the page portfolio my screen gives a whitepage.
This is my code
define("PLUGIN_DIR_PATH", plugin_dir_path(__FILE__));
add_filter( 'template_include', 'plugin_tweak_template', 99);
function plugin_tweak_template( $template ) {
if ( is_page('portfolio')) {
$template = PLUGIN_DIR_PATH . 'required/templates/portfolio.php';
}
return $template;
}
I use this code in my plugin root file.
I think the define path has a conflict.
define("PLUGIN_DIR_PATH", plugin_dir_path(__FILE__));
PLUGIN_DIR_PATH is a example in many tutorials but you can define this one time.
Is you have another plugin check the define name from this plugins if this is the same name you have a conflict.
Remember always: use variable names etc. by your own and prevent issues.
I'm trying to change the template of a specific product category page, but I can't for the life of me get it to work. I've tried taxonomy-product_cat-the-category but to no avail. I'm using wpml with the categories in 3 different languages if that makes a difference. I've tried with the slugs of each of the 3 langauges but still doesn't work. Don't understand what could be causing this.
First copy taxonomy-product_cat.php & archive-product.php from WooCommerce Plugin directory - wordpress\wp-content\plugins\woocommerce\templates to your theme - wordpress\wp-content\themes\your-theme\woocommerce.
Then make copy of archive-product.php files in your theme's woocommerce directory like archive-product-2.php, archive-product-3.php etc. Later you are going to modify these files as per your category.
Then open taxonomy-product_cat.php file. The code will look like below one.
if ( ! defined( 'ABSPATH' ) ) {
exit; // Exit if accessed directly
}
wc_get_template( 'archive-product.php' );
We need to modify the template call wc_get_template() in this code with our conditions.
First get the current category slug & then we can compare the slug. As per the slug, we will call different archive product files.
if ( ! defined( 'ABSPATH' ) ) {
exit; // Exit if accessed directly
}
// Get current category slug
global $wp_query;
$cat_slug = $wp_query->query_vars['product_cat'];
// Call template conditionally
if($cat_slug == 'accessories') {
wc_get_template( 'archive-product-2.php' );
} else {
wc_get_template( 'archive-product.php' );
}
Updates
In my experience, the best approach is avoid WooCommerce template overriding by copying in to theme files. The WooCommerce have regular updates on the templates and it is better to update templates on each time to avoid future issues. So if possible, maximum use filter hooks other than template overriding.
You can can't change the template of WP for a specific category but
For only overriding design: You can do css by using body.term-yourcategoryname at starting of each class, ID or tag name like this:
body.term-car h1 {
color: red;
font-size: 22px;
}
For enhancing Layout: or add some new feature you can use wooommerce default functions like: $term->name; in archive-product.php in your child theme.
example:
if($term->name == "car") {
// your code will goes here
}
I am having a bit of trouble here understanding how to do the following. I have searched for weeks now but cannot seem to find what I am looking for.
I have a custom post type 'product' and want to change which template gets loaded for the single product page as well as the archive for the products. I am using the following code to load include and load templates.
add_filter('template_include', function() {
if (is_post_type_archive('product')) {
$templatefilename = 'archive-product.php';
$template = WPVS_PATH . 'templates/' . $templatefilename;
return $template;
}
if ('product' == get_post_type() ){
$templatefilename = 'single-product.php';
$template = WPVS_PATH . 'templates/' . $templatefilename;
return $template;
}
});
The problem I am having is that it replaces the current theme's template instead of just the inner part of the content and archive areas.
Here is what I want to achieve:
Create a custom post type 'product' in a plugin - DONE (Was kinda easy!)
When opening a single product only change the content part. - I can do this with the_content filter hook. Simple enough. Any other suggestions is welcome.
When I go to the archive view for the 'product' custom post type I don't want to have it load the theme's default archive (list) view but instead a grid view from my plugin which I cannot seem to get right. I only want to change the inner part of the template, not the whole page.
I have created this plugin a few weeks ago using only shortcodes which works good but want to see if I can do it without the use of shortcodes by means of creating the custom post type and changing the inner template parts of the current active theme.
Can anybody steer me into the right direction here?
If I create a theme I can do what I am looking for but I want to create this into a plugin instead without adding or making changes to the active theme. The plugin should handle what is needed.
The same issue is discussed here but what I want is to develop something that is theme independent. No changes should be made in theme files and no theme files should be copied to the plugin.
WP - Use file in plugin directory as custom Page Template?
Recently I also had the same problem. Here's how I worked it out.
template_include filter accepts a parameter which is the selected template that you want to override (this what you are missing in your code).
I don't know but sometimes the filter hook need higher priority to work like 9999. But first check if it work with default priority, if don't change it.
I assume your both archive and single product template both have include get_header() and get_footer() which can be used for default selected theme (Or if the theme has different setup, setup accordingly).
This is simplified code:
add_filter('template_include', function($default_template) {
if (is_post_type_archive('product')) {
$templatefilename = 'archive-product.php';
$template = WPVS_PATH . 'templates/' . $templatefilename;
$default_template = $template;
} else if ('product' == get_post_type() ) {
$templatefilename = 'single-product.php';
$template = WPVS_PATH . 'templates/' . $templatefilename;
$default_template = $template;
}
// Load new template also fallback if both condition fails load default
return $default_template;
}, 9999); // set priority, only if not worked with default one
The best option in this case is to provide a shortcode to the user. So they can place it on any page that they want (or that you auto generate). That way you will place your content inside their theme.
Something like this:
add_shortcode( 'slotsl-game', 'embed_game' );
/**
* Print the game
* #return false|string
*/
function embed_game(){
ob_start();
$game = get_post();
include_once SLOTSL_PLUGIN_DIR . 'templates/slotsl-single-game.php';
return ob_get_clean();
}
I am building a full design into WordPress for the first time and I am trying to load in stylesheets and script files but all I seem to be getting is the text output of the location.
What I have is below..
wp_enqueue_style('reset', bloginfo('template_url') . '/reset.css');
wp_enqueue_style('style', bloginfo('stylesheet_url'), array('reset'));
wp_enqueue_style('rhino', bloginfo('template_url') . '/rhinoslider-1.05.css', array('reset','style'));
Do I need to put this inside the link tags or something? I thought it would do it all itself; as what's the point loading it that way if it doesn't do it itself? I know it makes sure the same file isn't included twice or something, but if you have to include the link tags yourself and then WP decides not to include the file then you are left with blank link tags!?
Lastly, should I set these up beforehand so I can just call them via their handles? If so, where? functions.php?
Edit: I also tried putting the below in my themes functions.php file but got the same results.
add_action( 'after_setup_theme', 'mmw_new_theme_setup' );
function mmw_new_theme_setup() {
/* Add theme support for post formats. */
add_theme_support( 'post-formats' );
/* Add theme support for post thumbnails. */
add_theme_support( 'post-thumbnails' );
/* Add theme support for automatic feed links. */
add_theme_support( 'automatic-feed-links' );
/* Add theme support for menus. */
add_theme_support( 'menus' );
/* Load style files on the 'wp_enqueue_scripts' action hook. */
add_action( 'wp_enqueue_scripts', 'mmw_new_load_styles' );
}
function mmw_new_load_styles() {
$foo = bloginfo('template_url') . '/reset.css';
$bar = bloginfo('template_url') . '/rhinoslider-1.05.css';
wp_enqueue_style('reset', $foo);
wp_enqueue_style('style', bloginfo('stylesheet_url'), array('reset'));
wp_enqueue_style('rhino', $bar, array('reset','style'));
}
When storing values in a variable via PHP use:
get_bloginfo()
So your new function would now look like:
function mmw_new_load_styles() {
$foo = get_bloginfo('template_url') . '/reset.css';
$bar = get_bloginfo('template_url') . '/rhinoslider-1.05.css';
wp_enqueue_style('reset', $foo);
wp_enqueue_style('style', bloginfo('stylesheet_url'), array('reset'));
wp_enqueue_style('rhino', $bar, array('reset','style'));
}
And be more semantic! It makes code for beginners easier to look at. ($foo could be $resetCssUrl)
I was having similar issues.
The register / enqueue scripts are so that you can globally assign your functions to load in the correct order. You can call them from the page that your working in but it is considered better practice do it this way.
My template has a functions.php but its nealry empty! It sepreates the scripts into 7 subchapters, theme-options, theme-functions, themes-js, etc. Here is my themes.js.php file but this could quite easily placed in your file inside your wp-content/themes/functions.php My themes-js.php file
I am writing a plugin that will take advantage of other plugin's features (think about a plugin for a plugin).
My file lies in /plugins/new-plugin/new-plugin.php
and I need to make a
include(/plugins/OLD_plugin/old-plugin.php)
so I can use a couple of functions from the old-plugin.php file.
What is the correct way to do this? I could maybe make the functions in old-plugin.php available globally, but I don't want to change the old-plugin.php file.
I've already tried several ways to do this, but none worked. The new-plugin will only show some info in an options page, not viewable for the general public and does not interact with any public page or post in my site.
I've already tried $_SERVER, WP_PLUGIN_DIR, WP_CONTENT_DIR, the absolute server path, relative paths and even some black magic, but nothing seems to work good.
With some of this solutions the plugin's options page shows good but the blog's pages do not render. With other solutions the inverse happens, and with some other solutions nothing even render, be it admin pages or blog's pages, all with errors regarding to file not found.
The new-plugin.php is as simple as
<?php
/*
WP Common Headers
*/
global $wpdb;
if ( ! defined( 'WP_CONTENT_DIR' ) )
define( 'WP_CONTENT_DIR', ABSPATH . 'wp-content' );
if ( ! defined( 'WP_PLUGIN_DIR' ) )
define( 'WP_PLUGIN_DIR', WP_CONTENT_DIR . '/plugins' );
include '/server-absolute-path/public_html/gameblogs/wp-content/plugins/old-plugin/old-plugin.php';
add_action('admin_menu', 'new_plugin_menu');
function new_plugin_menu() {
$page_title = 'New Plugin';
$menu_title = 'New Plugin';
$function = 'new_plugin_admin_page';
$menu_slug = 'new_plugin';
add_menu_page($page_title, $menu_title, 0, __FILE__, $function);
}
function new_plugin_admin_page() {
$result = old_plugin_link_data(" WHERE link_destination NOT LIKE '/%' AND link_destination NOT LIKE '%gameblogs%'");
$total = count($result);
old_plugin_list_links($result, $total, FALSE, FALSE);
*/
}
?>
thanks for any ideas!
check the old plugin files and see if there are any do_actions or apply_filters in it. If there are then you can hook into the old plugin script with your new plugin using add_action and apply_filters and execute other things you want to do.
see http://codex.wordpress.org/Function_Reference/do_action
and http://codex.wordpress.org/Function_Reference/apply_filters
For example (very basic example):
If in old plugin you find a:
do_action('some_type_of_reference);`
In your new plugin you can hook into it by doing:
`add_action('some_type_of_reference', 'name_of_my_function');
function name_of_my_function() {
//executed code here
}`
If in old plugin you find a:
apply_filters('some_type_of_reference', $variable);
Then in your new plugin you can hook into the filter by doing:
apply_filter('some_type_of_reference', 'my_function');
function my_function( $variable ) {
//act on the variable from the filter.
return $variable;
}
Have you looked at the plugins_url function? I haven't had an in-depth read through your code, but it might help.
The plugins_url template tag retrieves the url to the plugins directory or to a specific file within that directory. You can hardcode the plugin slug in $path or pass FILE as a second argument to get the correct folder name.
Hope this helps!
