want to swap wordpress colour scheme per category - php

I have a twenty-seventeen child theme, which i want to switch colour scheme per category, (from colors-custom to colors-dark - eventally it will have more color schemes)
but this isn't working
add_filter( 'body_class', function( $classes ) {
if ( is_category( 'x cateorgy' ) )
{
foreach($classes as $key => $class) {
if( $class == "colors-custom" )
{
unset($classes[$key]);
}
}
}
$classes[] = 'colors-dark';
return $classes;
}, 1000);
I've initially tried it with out the first conditional if (is category()) and it adds color-dark but the css doesn't change.

Simply target the body element css classes for specific categories. The twenty seventeen theme uses the body_class() function and outputs class names for everything.
Just write css styles for background colors for every category class.

Extend WooCommerce Product Filters plugin shortocodes

I am using Woocommerce with WOOF plugin (woocommerce filter). In particular, this plugin can display a filter that will only search in a specific product category using for example [woof taxonomies=product_cat:23] shortcode and display the results using the [woof_products taxonomies=product_cat:23] shortcode, where 23 is the category id of goods.
However, it is not always possible to specify a category in the shortcode itself, and I would like to implement functionality that allows you to use a shortcode like [woof taxonomies=product_cat:auto], which will automatically determine the current category using a specific function, for example, this (the function is tested and works):
function show_product_category_id() {
$cat = get_queried_object();
$catID = $cat->term_id;
if (empty($catID)) {
//
if (strpos($_GET['really_curr_tax'], 'product_cat')) {
$catID=str_replace('-product_cat', '', $_GET['really_curr_tax']);
}
else {}
}
else {}
echo $catID;
}
I can, of course, create a shortcode for this function, and add it to the theme's functions.php:
add_shortcode( 'show_product_category_id', 'show_product_category_id' );
and it will work. But I can't use a construction like:
[woof taxonomies=product_cat:[show_product_category_id]]
since nested shortcodes in Wordpress won't work. Therefore, apparently, I need to add to woocommerce the ability to specify not only product_cat:35, but also product_cat:auto.
How can i realize it? Or, is there also a way to use nested shortcodes in wordpress?
Of course that you can't nest shortcodes one in another, but what you can do is embed a shortcode in a another shortcode as follows:
function woof_current_product_category_id() {
$term = get_queried_object();
$term_id = 0; // Initializing
if ( isset($_GET['really_curr_tax']) && false !== strpos( $_GET['really_curr_tax'], 'product_cat' ) ) {
$term_id = (int) str_replace('-product_cat', '', $_GET['really_curr_tax']);
} elseif ( is_a($term, 'WP_Term') ) {
$term_id = (int) $term->term_id;
}
return do_shortcode("[woof taxonomies=product_cat:$term_id]"); // Always use return for a shortcode
}
add_shortcode( 'show_product_category_id', 'woof_current_product_category_id' );
Code goes in functions.php file of the active child theme (or active theme).
So the usage will simply be: [show_product_category_id]

Add custom css class for the search page filter

I'm trying to add a custom CSS class for the search page that uses WooCommerce Product Search.
Search pages path is like:
domain.com/shop/ixwpss=3&title=0&excerpt=0&content=0&categories=0&attributes=0&tags=1&sku=0&v=a3420e5a4c03
When I search for the number 3 that represents the tag for products.
I managed to add the class for the whole shop, with the following function but I want to add only for the search page. Can someone help me?
add_filter( 'body_class', 'add_body_classes' );
function add_body_classes( $classes ) {
global $post;
if ( is_shop() )
$classes[] = 'search';
return $classes;
}
Please update the code like below
add_filter( 'body_class', function( $classes ) {
if ( is_shop() ) {return array_merge( $classes, array( 'class-name' ) );}
}
Assuming that the search page is using the archive-product.php
If you are using a WooCommerce compatible theme then you have to go in your themes folder -> woocommerce and find the archive-product.php. If the override file does not exists then go to wp-content/plugins/woocommerce/templates/archive-product.php
And a if statement to check if is search or not like below:
if ( is_search() ) {
<body class="your-class">
} else {
<body class="regular-class">
// the content that is already in that file (archive-product.php)
}
*if the part (body class in your case) is not there you have to locate it and do the same (probably it's in your header.php)

How to repair the top navigation bar sticky position?

I use a WP 5.3 Twenty Seventeen child theme, but I don't want to edit templates, so I added a needed second (in fact it became the first in the displaying order) div wrap section to the top navigation menu with the bellow function. The problem is that I lost after this the fixed position of the menu (it is not sticky anymore now). How to remediate this? I played with the CSS code, but without success. The site in discussion is here.
function my_navigation_top( $slug, $name ) {
if( $name == 'top' ) { ?>
--- some content here ---
</div> <!-- wrap closed -->
<div class="wrap"> <!-- wrap opened -->
<?php }
}
add_action( 'get_template_part_template-parts/navigation/navigation', 'my_navigation_top', 10, 2 );
UPDATE
If instead of a second div wrap section I add a simple div section inside the wrap, the problem doesn't appear.
I am looking at the script file that sets the fixed class (that makes the top nav sticky when scrolling down). (File: twentyseventeen/assets/js/global.js)
And It seems the fixed class is not set if the height of the nav is too tall:
// Set properties of navigation.
function setNavProps() {
navigationHeight = $navigation.height();
navigationOuterHeight = $navigation.outerHeight();
navPadding = parseFloat( $navWrap.css( 'padding-top' ) ) * 2;
navMenuItemHeight = $navMenuItem.outerHeight() * 2;
idealNavHeight = navPadding + navMenuItemHeight;
navIsNotTooTall = navigationHeight <= idealNavHeight;
}
// Make navigation 'stick'.
function adjustScrollClass() {
// Make sure we're not on a mobile screen.
if ( 'none' === $menuToggle.css( 'display' ) ) {
// Make sure the nav isn't taller than two rows.
if ( navIsNotTooTall ) {
// When there's a custom header image or video, the header offset includes the height of the navigation.
if ( isFrontPage && ( $body.hasClass( 'has-header-image' ) || $body.hasClass( 'has-header-video' ) ) ) {
headerOffset = $customHeader.innerHeight() - navigationOuterHeight;
} else {
headerOffset = $customHeader.innerHeight();
}
// If the scroll is more than the custom header, set the fixed class.
if ( $( window ).scrollTop() >= headerOffset ) {
$navigation.addClass( navigationFixedClass );
} else {
$navigation.removeClass( navigationFixedClass );
}
} else {
// Remove 'fixed' class if nav is taller than two rows.
$navigation.removeClass( navigationFixedClass );
}
}
}
I am not entirely certain what the solution would be. One idea (which is not ideal) is to adapt the .js file and put true between the ( ) instead of navIsNotTooTall on this line:
if ( navIsNotTooTall ) {
If you want to add this change to the child theme, instead of the main theme: Put the changed global.js file in your child-theme directory here: twentyseventeen-child/assets/js/global.js
Then add this to functions.php of the child-theme:
add_action( 'wp_enqueue_scripts', 'override_globaljs_script', 100 );
function override_globaljs_script()
{
wp_dequeue_script( 'twentyseventeen-global' );
wp_deregister_script( 'twentyseventeen-global' );
wp_enqueue_script( 'twentyseventeen-global-child', get_stylesheet_directory_uri() . '/assets/js/global.js' );
}
It will unregister the main theme global.js and register it for the child theme. This is the 'proper' Wordpress way to do it as far as I am concerned.

WordPress category based template

I have a task to create a template which is specific to the category. So Lets say I have 10 categories but I want to create a specific template for lets say 3 of them. So if the category is a,b or c I will apply a certain template.
And then when I create a post and attach it to the specific category I need to show that specific template associated to the category.
Any headers?
The Advanced Custom Fields https://www.advancedcustomfields.com/ plugin should allow you to show different templates based off categories. It has some pretty fancy functionality, but can't remember if it can do exactly this.
There is a free version, so give it a try. Let me know how you go ;)
Delete everything in single.php
Insert the ‘switching’ code (see below)
Create 3(three) new templates with unique names. like : single-a,single-b,single-c.
On the server, the magical fairy dust in your modified single.php will automatically load the correct template when the page is requested
Please try below Code for the same.
if (in_category('21')) {include (TEMPLATEPATH . '/single-a.php');
}
else if (in_category('22')) {include (TEMPLATEPATH . '/single-b.php');
}
else if (in_category('23')) {include (TEMPLATEPATH . '/single-c.php');
}
else { include (TEMPLATEPATH . '/single-29.php');
}
There is single-a,single-b,single-c are 3 templates for different categories and your main code in it.
If you refer to Category_Templates
Wordpress will auto retrieve category files in the following format:
category-slug.php or category-ID.php
Let's say you have 3 categories, category a, category b, category c, to assign each of the template differently you can easily create category-a.php, category-b.php, category-c.php and place your desire template within the file and Wordpress will handle the rest.
Here you can use category_template
function wp_category_template( $template ) {
$cat = get_queried_object(); // get category object
if( 1 ) // check condition
$template = locate_template( 'template.php' ); // load template
return $template;
}
add_filter( 'category_template', 'wp_category_template' );
or as #shashi suggested you can use plugin custom-category-template
You have 3 options :
Option 1 : You can create 3 templates and name them according to the WordPress Template Hierarchy like this :
category-1.php
category-2.php
category-3.php
Option 2 : Use PHP code in your functions file to load 1 template for 3 different categories :
add_filter( 'template_include', 'custom_category_template', 99 );
function custom_category_template( $template ) {
if ( is_category(array( 1,2,3 ) ) ) {
$new_template = locate_template( array( 'custom.php' ) );
if ( '' != $new_template ) {
return $new_template;
}
}
return $template;
}
Use the in_category or is_category conditional tag depending on whether you want to load the template for posts in specific categories or only for the category archive page.
Option 3 : You can use the code in option 2 with the category_template filter :
add_filter( 'category_template', 'custom_category_template' );
function custom_category_template( $template ) {
if ( is_category(array( 1,2,3 ) ) ) {
$template = locate_template( 'custom.php' );
}
return $template;
}
Assumes your category i.d's are 1, 2 and 3. Swap out these to match your installations category i.d's

Wordpress category/post color menu

Can you tell me how you can make posts wordpress categories and with different colors?
I want to be the only menu in different colors as well as the category the items!
An example:
check out this site here that you like the color settings are changed as we post categories.
A lot of it depends on how your theme is set up, but here's a general overview:
1. Ensure that you are using the body_class() function
Check you theme's header.php and ensure the body tag looks something like:
<body <?php body_class(); ?>>
This will automatically add a bunch of classes to your body tag, including classes depending on which category archive page you are viewing.
2. Use a filter to add category classes to single posts
Insert the following function into your theme's functions.php file:
function my_body_class_add_categories( $classes ) {
// Only proceed if we're on a single post page
if ( !is_single() )
return $classes;
// Get the categories that are assigned to this post
$post_categories = get_the_category();
// Loop over each category in the $categories array
foreach( $post_categories as $current_category ) {
// Add the current category's slug to the $body_classes array
$classes[] = 'category-' . $current_category->slug;
}
// Finally, return the $body_classes array
return $classes;
}
add_filter( 'body_class', 'my_body_class_add_categories' );
This will also add the category classes to single posts.
3. Add classes for pages
The body_class() function can also be filtered to add classes for page slugs. Add the following to functions.php:
function my_body_class_add_page_slug( $classes ) {
global $post;
if ( isset( $post ) ) {
$classes[] = $post->post_type . '-' . $post->post_name;
}
return $classes;
}
add_filter( 'body_class', 'my_body_class_add_page_slug' );
This will add the class page-title to the body.
4. Style as you please
This will vary according to your theme's markup, but it will be along the lines of:
.td-header-main-menu {
background: blue; // The fallback colour for all pages
}
.category-showbiz .td-header-main-menu {
background: red;
}
.category-sport .td-header-main-menu {
background: yellow;
}
.category-shendetsi .td-header-main-menu,
.page-shendetsi .td-header-main-menu {
background: green;
}
Conclusion
That should give you the general idea; we can't give you more specific instructions without seeing the website itself or know which theme you're using.
