limit get_categories() to only three categories

  • Hallo everyone,

    I’m working on a website to wich I want to display three of the categories on the frontpage.

    This is the code I’m using:

    
					<?php 
                        $categories = get_categories( array(
							'orderby' => 'name',
							'hide_empty' => false,
                            'parent' => 0
                        ) );
                    ?>
                    
					<?php foreach ( $categories as $category ) : ?>
						<div class="grid-3">
							<div class="intro_linkToCategory">
                                <a href="<?php echo esc_url( get_category_link( $category -> term_id ) ); ?>">
                                    <img src="<?php echo z_taxonomy_image_url( $category -> term_id ); ?>" />
                                    <h2><?php echo $category->name; ?></h2>
                                </a>
							</div><!-- end of intro_linkToCategory -->                            	
						</div><!--  end of grid -->
					<?php endforeach; ?>

    This code, however, displays all the avaliable categories. I want to limit get_categories() to show a limited amount of categories by category ID. I might have searched on the wrong places but I couldn’t find a solution to do this. I don’t want to show the posts of a category but just list the category name and image (using a plugin for the image) and link it to the correct category page.

    I’d like a point into the right direction or an example of working code that will point me on the right direction. I have a deadline of April 1st ( not a joke ) on this one and I’m starting to get nervous…

    Thanks in advance,
    Kind regards.

    Hi Sajid

    Thank you for your answer. I have checked your code example. I’m looking for a way to be able to input the category id of the categories I want to display. Normaly with posts one can add the post id’s into the arguments array i’m looking for a simmilar thing, maybe with a different code approach.

    Thank you for taking time to answer my question nonetheless.

    kind regards,
    Vasco.

    the function takes the same arguments as https://developer.www.ads-software.com/reference/functions/get_terms/

    investigate the 'include' parameter …

    Hi Michael,

    thank you for your imput. It solved my problem. Funny thing is I had scanned trhough that page before but missed the point completely. This is my endcode for posterity:

    
<?php 
    $categories = get_categories( array(
        'include'=> array(78, 72, 76),
        'orderby' => 'name',
	'hide_empty' => false,
        'parent' => 0
    ) );
?>
                    
<?php foreach ( $categories as $category ) : ?>
    <div class="grid">
	<div class="intro_linkToCategory">
            <a href="<?php echo esc_url( get_category_link( $category -> term_id ) ); ?>">
                <img src="<?php echo z_taxonomy_image_url( $category -> term_id ); ?>" />
                <h2><?php echo $category->name; ?></h2>
            </a>
        </div><!-- end of intro_linkToCategory -->                            	
    </div><!--  end of grid -->
<?php endforeach; ?>

    the grid reference is part of amazium grid system wich I use for responsiveness.

    once again, thank you all for the imput.
