How do I retrieve the category ID (ugly permalinks) in my sub-navigation menu?

    I have recently faced multiple issues with a theme developed with in mind pretty permalinks when moving back to ugly ones (for a number of different reasons). Had issues that I resolved with categories and tags as displayed on my sidebar and also now have the same issue with categories in a custom navigation menu.

    Originally, the below code would take me to all the posts whose category is called ‘Amazing’, currently with the use of ugly permalinks (to which I need to stick now for a bunch of reasons) I am returned with a 404 error message. Here is an excerpt of my navigation:

    <nav class="my-nav-menu">
  <div class="myclass">
    <ul role="navigation" class="mymenuentries">
      <li class="col-clas">
         <a class="myotherclass" href="<?php echo home_url() ?>/category/Amazing">AmazingCategory</a>
      </li>
   </ul>
  </div>
</nav>

    The code will generate this URL:

    https://localhost/mywebsite/Amazing

    that returns a 404 message, whereas I know that the following will return all the posts associated to that category:

    https://localhost/mywebsite/?cat=12

    How can I dynamically make sure that the category is fetched by its ID? I am also very much not aware how that piece of code was actually working with pretty permalinks. Can you help?

    Thank you

    Hi Nagomitaro,

    As the category link is hard coded by name, why not just replace that with ?cat=12 permalink? So, instead of this 

    
href="<?php echo home_url() ?>/category/Amazing"

    Replace it with 

    
href="<?php echo home_url() ?>/?cat=12"

    Hi,
    Thank you for your reply. This is a good shout and tried it already, but I wanted to have a more dynamic way to retrieve the category ID rather than encoding it again via its ID. I have this:

    $cat_slug = 'Amazing';
$taxonomy = 'category';
$cat_link = get_term_link( $cat_slug, $taxonomy );

if ( is_wp_error( $cat_link ) ) {
   echo $cat_link->get_error_message();
} else {
    echo $cat_link;
}

    and I am trying to do something like this:

    <nav class="my-nav-menu">
  <div class="myclass">
    <ul role="navigation" class="mymenuentries">
      <li class="col-clas">
         <a class="myotherclass" href=". get_term_link($cat_link) . "'>AmazingCategory</a>
      </li>
   </ul>
  </div>
</nav>

    But I cannot get it to work. Where do I call the php code? Just before the nav class? is the get_term_link usage correct?

    Thank you

    Just realised that I only need to call $cat_link inside href. I have tried this:

    <li class="col-clas">
            <a class="myotherclass" href='{$cat_link}'>News.</a>
          </li>

    But that is not correct. Should I include the php code inside a function?

    Thank you

    Ok, it will be then something like this 

    
<a class="myotherclass" href="<?php echo $cat_link; ?>">News.</a>

    haven’t tried, but it should work.

    Hi,

    Thank you so much, it works fine. This is what I have ended up with:

    <nav class="my-nav-menu">
  <div class="myclass">
    <ul role="navigation" class="mymenuentries">
      <li class="col-clas">
         <a class="myotherclass" href="<?php $cat_slug = 'Amazing';
$taxonomy = 'category';
$cat_link = get_term_link( $cat_slug, $taxonomy );

if ( is_wp_error( $cat_link ) ) {
   echo $cat_link->get_error_message();
} else {
    echo $cat_link;
}?>">AmazingCategory.</a>
      </li>
   </ul>
  </div>
</nav>

    I have one additional question, in case I have more than one category, how can I make that more generic?

    Thank you

    For getting more then one category, you can use this function “get_categories”
