Thanks for taking the time to reply bcworkz.

I’m trying to write a plugin that returns JSON encoded results. A bit like JSON API but with the ability to query ACF fields and multiple taxonomy terms.

I’ve constructed my query (basic example in the question) which, if I leave out the tax_query part works fine. However with the tax_query as an argument it doesn’t return anything.

I wasn’t sure if WP_Query was the best way to approach this kind of query or whether I need to go down the $wpdb route.

Hi,

Thanks for the reply but I’ve just figured it out. Here’s how I ended up doing it. I realise that this may not the most perfect method but it works. If you have any suggestions post them up.

To clarify: the following code looks to see if a post has more than one tag, if it does it displays that tag as a header and displays the other tags with that tag below. If the post only has one tag it displays it as a link.

To demonstrate.
Post 1 has tags of ‘Music’ and ‘Rock’
Post 2 has tags of ‘Music’ and ‘Jazz’
Post 3 has a tag of ‘My Band’

It would look like this:
-Music
–Rock
–Jazz
-My Band

<?php
	//Set up an array to put all of the tags that have been used in drop-dwon
	$used = array();
	//Get all the tags
	$tags = get_tags(array('orderby' => '', 'order' => 'ASC') );
	//For each tag
	foreach ($tags as $tag) {
		$post_tag = get_term($tag, 'post_tag');
		//Get posts limited only to the current tag
		$t_posts=get_posts(array('orderby' => 'date', 'tag__in' => array($tag->term_id)));
		//If the post has more than one tag
		if ($post_tag->count > 1) {
			//Display the drop down title (e.g if two posts were tagged with 'Music' this would diaply that 'Music' title
			echo '<h4 id="' . $tag->term_id .'">' . $tag->name . '</h4> <br />';
			//Declaring the title as a variable for later use
			$taghead = $tag->name;
			//For each post with the current tag
			foreach($t_posts as $t_post) {
				setup_postdata($t_post);
				//Get all of the posts under the current title
				$the_tags = get_the_tags($t_post->ID); foreach($the_tags as $the_tag) {
				//Don't diaply the current tags title
				if ($the_tag->name == $taghead) continue;
				//Display the tag under the title
				echo '<p class="tag-' . $the_tag->term_id . '"><a href="' . get_tag_link( $the_tag->term_id ) . '">' . $the_tag->name . '</a></p>';
				//Push the current tag into the used array
				array_push($used, $the_tag->term_id);
			} //End foreach tag
		} //End foreach
		//If the post only has one tag then link to it as an archive
		} else {
			//If the tag has already been displayed above don't show it here
			if (in_array($tag->term_id, $used)) continue;
			//Display the rest of the tags
			echo '<h4 class="tag-' . $tag->term_id . '"><a href="'. get_tag_link( $tag->term_id ) . '">' . $tag->name . '</a></h4><br />';
		} // End else
?>

Does anyone know how I might even start to do this – I’m really stuck?

Thanks

Thanks for the response Michael.

I think I see what you mean, so, for instance if I was going to display the posts ID under the tags title I would do as follows:

<?php $posthead = get_posts(array('orderby' => 'name', 'order' => 'ASC', 'category' => '3,5,6,7,8'));	foreach($posthead as $post) : setup_postdata($post); ?>
 		<?php $posttags = get_the_tags($post->ID);
		foreach($posttags as $tag) {
			echo '<h2>' . $tag->name . '</h2>';
			echo '<p>' . $post->ID . '</p>';
		}
	?>
 <?php endforeach; ?>

However my main problem is that it will display the tag title and then the post title underneath for each post. So for example if I had two posts tagged with ‘music’, then it would look like this:

Music
band_1
Music
band_2

Thanks

I’ve figured out what I think is the best way to approach it but I still need help with its completion:
I use:
<?php query_posts(array('category_name' => 'news', 'post__not_in' => array(31))); ?>
This would exclude, in this instance, the post with the ID of 31.

So now I need to make it dynamic. My knowledge of php isn’t great, but I thought declaring a variable of the current post would work, so something like:

<?php
$excludeid = 31;
query_posts(array('category_name' => 'news', 'post__not_in' => array($excludeid)));
?>

This worked fine. So to make it dynamic my logic was to go with:
$excludeid = the_ID();

But this just doesn’t work, would anybody help me to try and make this dynamic?

Thanks

Thanks esmi,

I managed to figure out by simply looking up the ‘wp_list_pages’ in the codex, there I was able to find that there is in fact a parameter that can be passed called ‘link_after’, which does what I want. So to display a / character after each link I would simply just pass the parameter like this:

wp_list_pages(‘title_li=0&sort_column=menu_order&link_after= /’);
