This is a bit over my head….$display_categories = array

  • I think this has something to do with me trying to mix strings and arrays….Help please to combine the $option into the array….

    <?php
  $categories = get_categories('child_of=20');
  foreach ($categories as $cat) {
  	$option = '';
	$option .= ''.$cat->cat_ID.', ';

	echo $option;
	// This currently outputs: 21, 22,   I need to insert this for the array below like this: $display_categories = array(21, 22,);
  }

  // enter the IDs of the categories to display
$display_categories = array(21, 22,); // I tried entering array($option); here and only get the last category
  foreach ($display_categories as $category) { ?>
  <?php query_posts("showposts=1&amp;orderby=rand&amp;cat=$category"); ?>
  <?php while (have_posts()) : the_post(); ?>
	<div class="cat-3content">
  		<div align="center"><a href="<?php echo get_category_link($category);?>"><?php echo the_excerpt(); ?></a>
  		</div>
  		<h6><a href="<?php echo get_category_link($category);?>"><?php single_cat_title(); ?></a></h6>
	</div>
  <?php endwhile; ?>
<?php } ?>

  • You can just set the array in your first foreach loop:

    <?php

$display_categories = false;
$categories = get_categories( 'child_of=20' );

foreach ( $categories as $cat )
	$display_categories[] = $cat->cat_ID;

if( $display_categories ) {
	foreach ( $display_categories as $category ) {
		query_posts( "showposts=1&amp;orderby=rand&amp;cat=$category" );
		while ( have_posts() ) {
			the_post(); ?>
			<div class="cat-3content">
				<div align="center"><a href="<?php echo get_category_link($category);?>"><?php echo the_excerpt(); ?></a></div>
				<h6><a href="<?php echo get_category_link($category);?>"><?php single_cat_title(); ?></a></h6>
			</div>
	  <?php
		}
	}
}
?>

    Oh dear…sorry about that

    try here… this is using your new code (with thanks)

    https://clients.popcornphotography.com.au/category/events

    I am using photoq which publishes a thumbnail as the_excerpt for each post.

    I want to show a random thumbnail from, and the category title of each child category.

    I have used the old code here to show how I would like it to look

    Cheers and once again Many Many Thanks

    Hmm… look at here:

    query_posts( "showposts=1&amp;orderby=rand&amp;cat=$category" );
		while ( have_posts() ) {

    See the part that says:

    showposts=1

    This will force the loop to only return one result. Your page is displaying 2 results which is most likely due to the foreach loop the encases the “WordPress Loop”.

    Try removing showposts=1 and let me know what happens.

    Hmmm…that didn’t work…I’ll go back to changing it manually when I put a new client category up..

    Many thanks for your help
