I'm currently using a wordpress function in order to display posts from a specific category. A simplified example is shown below:
<?php query('cat_name=cat1&posts=1') ?>
Essentially this gets 1 post from the category cat1.
However I have a variable saved which gets the current category (this is on category pages):
<?php $thiscat = get_the_category(); ?>
Current Category: <?php echo $thiscat ?>
How can I now echo the variable $thiscat into the arguments of my query above so that the category name is filled in for me? This function is applied on different category pages so having it automatically passed to the arguments of my query saves a lot of hassle.
Thanks in advance for any help.
You only echo something when you want to output it to the browser, here we concatenate the query string with the variable:
<?php $thiscat = get_the_category(); ?>
<?php query('cat_name=' . $thiscat . '&posts=1') ?>
Not sure I understand the question, but it sounds like you want to use $thiscat in your query. This should do it:
<?php
$thiscat = get_the_category();
query("cat_name=$thiscat&posts=1")
?>
Note the double quotes, which are necessary. If you use single quotes, the variable will not get expanded.

Is it possible to only show the code below if there's a category description?
<h2>About <?php $cat = get_the_category(); echo $cat[0]->cat_name; ?></h2>
<?php $catID = get_the_category(); echo category_description ( $catID[0] ); ?>
I have these codes on my single posts in Wordpress but sometimes, I forgot to add descriptions on a new category that I added. So when a user visits the post, they will just see the word About Category and no description at all, making it looks like an incomplete article.
I'm not a developer and I'm also not familiar with PHP. I only added that code on the single.php to show the description. But I want it not to show when there's no description available.
Hope someone can give me the exact code to make it work.
Thanks!
Good practice to assign your values into variables at the top of your script before entering into HTML whenever possible. This will help prevent you making redundant calls and to debug your code better. Once you have your assigned values, you'll want to check if the value is empty. I am assuming the code you presented will always return some kind of value for index 0.
<?php
$cat = get_the_category();
$cat_0 = $cat[0];
$cat_0_name = $cat_0->cat_name;
$cat_0_desc = category_description($cat_0);
?>
<?php if(!empty($cat_0_desc)): ?>
<h2>About <?php echo $cat_0_name; ?></h2>
<?php echo $cat_0_desc; ?>
<?php endif; ?>
I should like to point out that I am choosing to use an alternative syntax for control structures versus the traditional brace control. This will make your code more readable and easily debugged when mixed in with HTML.
If your code is still throwing you errors, I would suggest you check your error logs as something would be happining during the get_the_cateory() call or that it's not returning any values resulting in error with $cat[0].
<?php if ($cat = get_the_category() && count($cat)>0) { ?>
<!-- <?php echo print_r($cat,1); ?> -->
<h2>About <?php echo $cat[0]->cat_name;?></h2>
<?php echo category_description ($cat[0]->cat_id); ?>
<?php } ?>
I'm trying to do something that seems really simple but I can't figure it out.
In my category template, I have this shortcode:
<?php echo do_shortcode( '[jobs categories="manufacturing"]' ); ?>
I also have this to show the title of the category:
<?php single_cat_title(); ?>
I would like to put them both together so I can pass the category into the shortcode so it fetches the correct job category listings. So I created this:
<?php $category = single_cat_title(); ?>
<?php echo do_shortcode('[jobs categories=' . $category . ']'); ?>
but it doesn't seem to work properly - Am I doing something wrong? Is this even possible?
Many thanks!!
If you look at the documentation for the single_cat_title() function, you'll see that it can either display or return the value, and it accepts two parameters $prefix and $display with default values of '' and true respectively.
What this means, is that just using single_cat_title(); will print Category Title to the document.
If you want to use it as a variable (without printing it to the document), you'll need to set the second parameter to false:
$category = single_cat_title( '', false );
This will define the $category variable for you, without printing anything, and you can then pass it to your shortcode (also note, that typically you'll want quotes around your attribute values in shortcodes):
echo do_shortcode( '[jobs categories="' . $category . '"]' );
You can make it a bit more succinct as well:
<?php
$category = single_cat_title( '', false );
echo do_shortcode( "[jobs categories='$category']" );
?>
I am trying to show the amount of posts each users on my WP site has posted.
Currently the code I have is:
<?php
$author_id = the_author_meta('ID');
echo count_user_posts('$author_id');
?>
As you can see I am storing the author ID in $author_id and running that in the count_user_posts() echo.
When I run the to strings separately it works however when, I combine them as above it doesn't.
Any ideas?
Regards,
You should use get_the_author_meta for this kind of purposes.
$author_id = get_the_author_meta('ID');
echo count_user_posts($author_id);
the_author_meta should be used only for echoing stuff.
Try to use it like this :
<?php
$author_id = the_author_meta('ID');
echo count_user_posts($author_id); // remove quotes
?>
Hope it works for you now.
I found you need to add your post, page or your_custom_post_type for it to work successfully.
<?php echo 'Posts made: ' .(count_user_posts(get_the_author_meta('ID'),'your_custom_post_type') ); ?>
// or multiple post types
<?php echo 'Posts made: ' . count_user_posts( get_the_author_meta('ID'),['job', 'featured_job', 'free_job'] ); ?>
I'm trying to find the category ID of a post and then use it in the short code below. To find the category id I'm using <?php the_category_ID(); ?>, but i'm not sure how to use the output from category id and replace it in include_categories=. i.e. i want to replace number 4 with the current category ID i got from <?php the_category_ID(); ?>.
<?php echo do_shortcode('[include_categories="4"]'); ?>
i tired doing the following, but it didn't work. Any ideas will be appreciated.
<?php echo do_shortcode('[include_categories="<?php the_category_ID(); ?>"]'); ?>
I know i can't use php inside another php code, but i'm not sure how to place the category id between the quotation.
Thanks.
A couple of things: (1) you can't have nested <?php ?> tags, (2) the_category_ID() has been deprecated since WordPress 0.71. You'll want to use get_the_category() instead.
The correct solution would be:
<?php echo do_shortcode('[include_categories="' . get_the_category() . '"]'); ?>
The dots . "concatenate" the string with the returned values of get_the_category(). You can read more about string operators in the PHP docs.
Try with -
<?php echo do_shortcode('[include_categories="'.the_category_ID().'"]'); ?>
Use this to add php verial in short code:
<?php $category=the_category_ID();
echo do_shortcode("[include_categories=$category]"); ?>
I have a code that can get me the category_id of an item. This is the code:
<?php echo lavada_category_id() ; ?>
I want to know how I can add this code. Inside this, I want to replace the number 2 in here;
<?php lavada_query_item("category=2");?>
with:
<?php echo lavada_category_id() ; ?>
I know you cannot do like this
<?php lavada_query_item("category=<?php echo lavada_category_id() ; ?>");?>
But how can I do it?
Why not store it into a variable and then use that variable?
<?php
$catID = lavada_category_id();
lavada_query_item("category={$catID}");
?>
OR if you just want category ID to be passed into lavada_query_item do this:
lavada_query_item($catID);
The syntax error that you have is that you can not use <?php within <?php
You just need to concatenate the string like this:
<?php lavada_query_item("category=". lavada_category_id() );?>
I think this is what you are looking for:
<?php lavada_query_item(lavada_category_id());?>
The value returned from thelavada_category_id() function will be passed into the lavada_query_item() function.
