On my WordPress theme, it displays all of the categories a post is in on the homepage for the post block, I only want to display one category even if a post is under multiple categories.
i.e. Category One, Category Two, Category Three
I want it to be Category One...
This is the code that is in place at the moment:
<h2><?php the_category(', ') ?></h2>
<?php
$category = get_the_category();
echo $category[0]->cat_name;
?>
What do you mean by first category? The following code will show only the one category, but it will sort the categories by name.
<?php wp_list_categories('orderby=name&show_count=1'); ?>

i want to display multiple categories with their post counts with help of short code without plugin.
i found many functions code here but didn't work with multiple categories with shortcode.
how to create function that is use to display all categories post counts using shortcode.
Example:
category 1: 20 posts
category 2: 10 posts
category 3: 15 posts
the display results 20,10 or 15 should be shown by help of shortcode.
This is a basic way to show a list of categories with their post counts. You could use other objects to link to the category pages etc. From what you described you just need a list, but this is the foundation.
function category_post_count() {
ob_start(); //php output buffer
$categories = get_categories(); ?>
<ul>
<?php foreach($categories as $cat) { ?>
<li><?php echo $cat->name . ': ' . $cat->count; . ' posts '; ?></li>
<?php } ?>
</ul>
<?php $endBuffer = ob_get_clean();
return $endBuffer;
}
add_shortcode( 'category_post_count', 'category_post_count' );
Then all you need to do is add this to the area where you want it to show up on the page...
[category_post_count]
Basically, I want to hide the category list if the author hasn't chosen a category for the post yet (so that it doesn't show 'uncategorised' on the archive page).
I need to check if the post is ONLY in the 'uncategorised' category in Wordpress.
I am checking if the post is in this category with:
<?php if (!in_category( 'uncategorised' )) { ?>
<div class="category">
<?php the_category(', '); ?>
</div>
<?php } ?>
Which works great - however any post that is in 'uncategorised' AND another category is also not appearing. So, i need to also check if that is the ONLY category it is in. So something like '&& is only in one category' is what i'm looking for, but my google searches have not come up with any solutions.
Please could someone point me in the right direction with this?
There is a built in function that could help you here:
https://codex.wordpress.org/Function_Reference/get_the_category
Example of ”only one category”:
$categories = get_the_category()
if ( count($categories) == 1 ) { ... }
I want to display only the category name within The Loop, without link, markup or anything else. This:
<?php the_category(); ?>
only gets me the category name as a list object with a link.
This will work:
$category = get_the_category();
echo $category[0]->cat_name;
I'm using the Custom Field Plugin to add a custom Field and call it to the content using the_field(); in my single.php
I just want to display this field on the all the categories except the "Articles which is 13", so I was trying somethin' like this:
<?php if !is_category( '13' ); { ?>
<h3 class="single-product__price"><?php the_field('precio'); ?></h3>
<?php } ?>
But it is not working. I'm wondering how to do this.
You should use in_category, and put the conditional statement in parentheses.
<?php if (!in_category( $cat )) { ?>
<h3 class="single-product__price"><?php the_field('precio'); ?></h3>
<?php } ?>
Make sure $cat is either ID (integer), name or slug (string) of the category.
Edit: I'm assuming you actually want to display the input on posts that are not in a particular category, hence in_category. If you do indeed want to display it on all other Category archive pages, then is_category would be correct.
I am looking to list on the product page the categories that a particular product belongs to; HOWEVER, I would like to be able to say do NOT list some specific categories.
A solution to outputting the list of categories a product belonged to was posted by a fellow stackoverflow user here: https://stackoverflow.com/a/9720480/99112 and it works great to output the results. How could the above code be modified to get what we are looking for?
Just to draw up an example of what I mean:
Say a Product A is a member of Category IDs: 4, 7, 9, 14, 92
On the product page, I want to output the names of the above categories MINUS category IDs: 7, 92
So, the output would only be Category ID names for: 4, 9, 14
The categories we would want to exempt would apply to all products. So in the above example and looking at a Product B, it would also output Category ID names EXCEPT for the ones we don't want (i.e. 7, 92).
Here is the code in question from the above thread (thanks to user "Sarath Tomy"):
<?php $categories = $_product->getCategoryIds(); ?>
<?php foreach($categories as $k => $_category_id): ?>
<?php $_category = Mage::getModel('catalog/category')->load($_category_id) ?>
<?php echo $_category->getName() ?>
<?php endforeach; ?>
How would we modify this to check a list of Category IDs that we do NOT want outputted, please?
Many thanks.
Here's a solution that worked (no idea if it's the most efficient way of doing it or not), but here it is:
<?php $categories = $_product->getCategoryIds(); ?>
<?php foreach($categories as $k => $_category_id): ?>
<?php $_category = Mage::getModel('catalog/category')->load($_category_id) ?>
<?php if (!in_array($_category->getId(), array(XX,YY))) : ?>
<?php echo $_category->getName() ?>
<?php endif; ?>
<?php endforeach; ?>
where you put in whatever Category IDs you want to exclude in place of XX,YY above.
You could make a System - Configuration setting that contains a multiple select with all the categories.
The categories selected would be the ones excluded.
Now, the best practice would be to extend Mage_Catalog_Model_Product, and add another method getVisibleCategoryIds()
Here's how it would look (not tested):
public function getVisibleCategoryIds() {
return array_diff($this->getCategoryIds(), Mage::getStoreConfig('section_name/group/field'));
}
Or you can extend getCategoryIds() directly and save the hassle of modifying through templates. This would look like this:
public function getCategoryIds() {
return array_diff(parent::getCategoryIds(), Mage::getStoreConfig('section_name/group/field'));
}
