Updated for 1.2 & 1.3: Adding category depth tag to Shopp

Problem: I needed to display sub categories of a category in category.php but only one level deep. Using:

<?php if(shopp('category','hascategories')): ?>
  <?php while(shopp('category','subcategories')): ?>
    //display stuff
  <?php endwhile; ?>
<?php endif; ?>

…displays all subcast AND their subcats. Continue reading “Updated for 1.2 & 1.3: Adding category depth tag to Shopp”

Remove ‘ul’ and ‘li’ tags from WordPress menus while retaining all the classes

Problem:
I need to output a WordPress nav menu as a series of anchors surrounded by spans, within one nav element. Manipulating the args passed to wp_nav_menu() function will allow the <ul> element to be removed, and passing the output through ‘striptags’ can remove the <li> elements, but I end up losing all the link ancestry classes.

Solution:
If a ‘Walker’ class is used, the output from wp_nav_menu() can be controlled totally. Here’s an example that removes the list elements, adds a span around each item link, and adds the possibility of a separator string between each menu item.

Add to your theme / header / etc: Continue reading “Remove ‘ul’ and ‘li’ tags from WordPress menus while retaining all the classes”

Custom Ordering Shopp (wordpress plugin) products in just one category

Problem: I’ve developed a site using the Shopp ecommerce WordPress Plugin and product ordering is set to ‘Price – Low to High’ at the Client’s request. Splendid. But now – for one category only – he want’s the Products to be give a custom order. In the Shopp presentation settings, ‘Product Order’ is set site-wide.

Solution: I created a custom template for the category in question, then in that template loaded the specific category with the ‘order’ option set to ‘custom’. Here are some steps.

1) Create the category specific template in the ‘Shopp’ theme templates directory in your WordPress theme. In my case the file was called category-truss.php as ‘truss’ is the slug of the category, and it’s a copy of my main category.php template file.

2) At the top of category-truss.php add the API function shopp(‘storefront.category’) like so:

<?php shopp('storefront','category','slug=truss&load=true&order=custom'); ?>
// load=true is needed to stop the functioning spitting out the category directly.
// slug is whatever your category's slug is. See the docs for more 'order' options.

3) In the Shopp Admin area, edit the category you want to custom order, then use the ‘Arrange Products’ button/link. Then drag the products into the order you want and test.

It might be that there’s an easier or better way to do this, if so please let me know in the comments!

Exclude a WordPress Post Category across the whole site… but not custom queries.

Problem: On my latest project there’s a WordPress post category that only ever displays in a sidebar. I never want it to display in a ‘main’ loop posts on an archive page (whether it be the blog home, date archives, author archive etc etc. Until now I’ve been using ‘query_posts()’ and doing something like this in the main templates like home.php and index.php:

<?php $catObj = get_category_by_slug('my-cat-slug');
query_posts( 'cat=-'.$catObj->term_id );
if ( have_posts() ) :
	while ( have_posts() ) : the_post(); ?>
		<!-- Show stuff init! -->
	<?php endwhile;
endif;?>

This works… but I have to do it everywhere the loop is used, and when you dig into WordPress Templates that’s a lot of places.

Solution: There’s always a way to do something globaly in WordPress using Filters, Actions, or Classes in your theme’s functions.php file (or a plugin even). In this case we can use the ‘pre_get_posts’ action in functions.php to exclude the category for all main queries: Continue reading “Exclude a WordPress Post Category across the whole site… but not custom queries.”

wp_get_attachment_image_src() is NOT working, broken, failed, blaa…

Problem: No matter WHAT I do, wp_get_attachment_image_src() is NOT working. I JUST want the featured image source of this $post->ID.

Solution: Yes is probably is working… but stupidly I’m trying to pass it the POST ID and not the ATTACHMENT ID like I should be. The Attachment ID can be found with the get_post_thumbnail_id() function, and then passed like this:

1
2
$thisimg = wp_get_attachment_image_src(get_post_thumbnail_id($arr->ID),full);
print_r($thisimg); //shows the Array of bits you need.

Duh… me.

Zurb Foundation Tooltips for and WordPress thumbnails

Problem: I wanted to use Foundation 4’s tooltips on some WordPress post thumbnail (featured) images, but wasn’t sure how to add the necessary data attribute and classes.

Solution: It turns out after some playing about that an array of attributes can be passed to the WordPress ‘get_the_post_thumbnail()‘ function. Firstly we need to add the class ‘has-tip’ (and any extra positioning classes like ‘tip-top’ if that’s where we want the tooltip to appear – see the Foundation Docs link at the top). We then need to add the data attribute ‘data-tooltip’. An example of how to do this is in the following code where I pull out a value from an Advanced Custom Field, and display a list of images with tooltips:

1
2
3
4
5
6
7
8
$icons = get_field('accom_spec_icons');
if ($icons && !is_wp_error($icons)) {
	echo '<ul class="small-block-grid-4">';
	foreach($icons as $icon) {
		echo '<li>',get_the_post_thumbnail($icon->ID,'box-thumb',array('title'=>trim(strip_tags($icon->post_title)),'class'=>'has-tip tip-top','data-tooltip'=>'')),'</li>';
	}
	echo '</ul>';
}

It’s important to add the ‘data-tooltip’ attribute with a value of ”, otherwise it wont be inserted into the generated image tag correctly.

Removing
tags around WordPress Shortcodes while retaining wpautop() changes.

Problem:
I’m building something using Drew Morris’ Foundation 4 Theme for WordPress (http://fwp.drewsymo.com/) and it allows shortcodes like [row] and [column] to be used, so that content can be aligned to the grid.

The problem is, when those shortcodes are used with any sort of line break after them, wpautop() plays havoc with the markup. I could just disable wpauto() with `remove_filter( ‘the_content’, ‘wpautop’ );` but I want it to effect all other content.

Solution:
Wordpress 3.6 has an nice new tag called has_shortcode() which can be used along with some RegEx and preg_replace() to replace the offending <br /> tags. Here’s my first version… it can be improved but it’s working pretty well so far!

add_filter ('the_content', 'cleangridshortcodes');
function cleangridshortcodes($content) {
  if(has_shortcode($content,'row') || has_shortcode($content,'column')) {
    $patterns = array("/([row])
/","/([column(.*)])
/","/([/column])
/"); $replacements = array('$1','$1','$1'); $content = preg_replace($patterns, $replacements, $content); } return $content; }

Accessing selected payment type in Shopp Summary.php (Checkout and Order Confirmation page)

Problem: Someone on the Shopp Helpdesk asked how they could display the payment type that a customer had just selected, on the following Order Confirmation page. They were using multiple ‘Offline Payment’ type options, and presumably they needed the customer to be able to visually confirm what they’d selected. As far as I can see, there’s no template tag provided for this.

Solution: All sorts can be pulled from the ShoppShopping() object directly. In this case the following worked:

1
<?php echo ShoppShopping()--->data->Order->Billing->cardtype; ?>

Bonus: To display the same info in reciept.php, the following can be used:

1
<?php echo shopp('purchase','cardtype','return=1'); ?>

Get ID of the WordPress ‘Front Page’ in Theme’s functions.php

Problem: I wanted to add some Meta Boxes to the homepage only, and have them only visible in WP-Admin when editing that page.

Solution:  Provided that a page has been selected in wp-admin > General Settings > Reading Settings > A Static Page [Front Page], then this code can be used to pull that value out as a Page ID: Continue reading “Get ID of the WordPress ‘Front Page’ in Theme’s functions.php”
