So, I am using this to get the URL:
<a href="/category/<?php foreach((get_the_category()) as $category) { echo $category->cat_name . ' '; } ?>">
Which is outputting:
http://example.com/category/whatever%20category/
instead of:
http://example.com/category/whatever-category/
How can I make it do the latter?
Much thanks.
Try this
<a href="/category/<?php foreach((get_the_category()) as $category) { echo $category->slug . ' '; } ?>">
Hope this helps.
I think it will be easier to make use of the category slug, and not the name. It is already in lowercase and hyphen separated if you have more that one word.
The problem with using the name and adding hyphens is that you will not get a match and most probably just 404. %20 is how blank spaces is encoded in a URL.
You can just replace $category->cat_name with $category->slug
Just for interest sake, if you have to use the name and replace blank spaces with a hyphen, you can use str_replace()
$hyphened_name = str_replace( ' ', '-', $category->cat_name );
Change this: echo $category->cat_name
To this: echo $category->cat_slug
A better way would probably be to use:
$cat = get_the_category();
$cat_link = get_term_link( $cat );
That will have $cat_link as the full permalink.
echo '<a href="' . $cat_link . '">' . $cat->cat_name . '</a>';
Using your code above:
<a href="<?php
$cat = get_the_category();
echo get_term_link( $cat );
?>">
Personally, I try to avoid intermixing things like that as it gets to be a pain to read, but the above should replace what you have.
Better would be
<?php
$cat = get_the_category();
$cat_link = get_term_link( $cat );
echo <<<HTML
<a href="{$cat_link}">{$cat->cat_name}</a>
HTML;
?>
That would also replace what you wrote.
