Wordpress：如何获取特定类别的链接

Question

Okay, on my blog I have four categories that the user can click to. Management, Industry News, Productivity etc.

Requirement : I need to find a way using php to link to each category page.

        <div class="categories-section">
        <div class="category">
        <?php 
            $categories = get_categories();
            foreach ($categories as $cat) {
                if($cat->cat_name = 'MANAGEMENT') {
                 $category_link = get_category_link($cat->cat_ID);
                }

            }
        ?>

            <a href="#"><img class="category-icon" src="<?php bloginfo('template_url');?>/img/desktop/images/category-icon-1.jpg">
            <h3> INDUSTRY NEWS</h3></a>
        </div>
        <div class="category">
            <a href="<?php echo $category_link; ?>"><img class="category-icon" src="<?php bloginfo('template_url');?>/img/desktop/images/category-icon-2.jpg">
            <h3> MANAGEMENT</h3></a>
        </div>
        <div class="category">
            <a href="http://localhost/wordpress/category/PRODUCTIVITY/"><img class="category-icon" src="<?php bloginfo('template_url');?>/img/desktop/images/category-icon-1.jpg">
            <h3> PRODUCTIVITY</h3></a>
        </div>
        <div class="category">
            <a href="http://localhost/wordpress/category/PERSONAL-DEVELOPEMENT/"><img class="category-icon" src="<?php bloginfo('template_url');?>/img/desktop/images/category-icon-2.jpg">
            <h3> PERSONAL DEVELOPEMENT</h3></a>
        </div>          
    </div>

Problem: The page css is breaking and it's not working, currently the only way I can to link to category is to hard code it.

Ideas?

Answer 1

You are missing an equal sign ( = ) in the if -condition in your foreach .

if ($cat->cat_name == 'MANAGEMENT') {
    $category_link = get_category_link($cat->cat_ID);
    break;
}

You should also break after the result has been found so you don't loop over the other categories.

Update:
I'm not sure if there is a better function in Wordpress to do this, but you could save all links in an associative array to get all links at once.

$wp_categories = get_categories();
$categories = [];
foreach ($wp_categories as $cat)
    $categories[$cat->cat_name] = get_category_link($cat->cat_ID);

Now you can do the following:

// Management link:
echo $categories['MANAGEMENT'];
