[Feature Request] Get specific term image, not queried term image

2046,
This is an oversight on my part … Had no idea that get_term_children() even existed. It’s really rare that I will use term hierarchies though. Please provide the context that you will be using this function and I’ll see what I can do bout coming up with a filter for it.

I do not believe that creating a “give me image of this term ID.” is the correct way of handling this. It’s not that it is hard, it’s just not in users best interest’s. Please read above for explanations as to why.

The best solution here would probably be to create new filter that is hooked to a recursive function which will filter an array of term objects. This way devs can use whichever core functions they need to to get the terms that they need and then pass them through the filter which will query all of the images in one pass caching the image objects as well as their meta and adding a new property of image_id to each object in the array.

In the old version of your plugin a was able to do it by calling
do_action( ‘taxonomy_image_plugin_print_image_html’, ‘thumbnail’ ); (if I remember right), and so I thought I’ll be able to do it again by new function of the new version, but haven’t found one.

Yeah, this was deprecated in version 0.6 … unfortunately there is no new method for this. I think that it is not really necessary.

So I thought a would use “taxonomy-images-get-terms” as you mentioned in your description, but haven’t been able to figure it how.

Sorry to hear this. While, I feel that the documentation of the plugin is pretty good … I’m starting to realize that it is insufficient for many uses. I’ll be fixing this by creating a site with mini tutorials dedicated to this plugin. I think that a more “process oriented” documentation will be easier for users to integrate with their themes.

There will also be integrations with Taxonomy List Shortcode (waiting for WordPress 3.2 so I do not need to include a nasty workaround. see 18128) as well as widget support in Taxonomy Image plugin.

I do not need neccesarily the picture ID. The image url, or similar output is also pretty sufficient.

It’s really easy to use the ID to do anything you want. You can pass it to core functions to get the image’s src, html markup, metadata or complete post object:

Here’s one way to get the source:

$img = wp_get_attachment_image_src( $term->image_id, 'thumbnail' );
if ( isset( $img[0] ) ) {
	$src = $img[0];
}

The get_the_terms() and get_terms() wrapper functions were introduced to extend core functionality by providing the image ID + caching the images. I’ll see about writing better tutorial-style docs for the usage. Until then post the code you are using and what it needs to do and I’ll take a look.

Sorry, was a bit tired when I wrote this. I was trying to illustrate new functionality that I would add to the plugin. This should be clearer:

$terms = get_terms('category','child_of=4242');
$terms = apply_filters( 'taxonomy-images-setup-terms', $terms );
foreach ($terms as $term){
  $img = wp_get_attachment_image_src( $term->image_id, 'thumbnail');
    if ( isset( $img[0] ) ) {
  	$src = $img[0];
    }
}

This filter would allow you to get an array of terms using any core function and then filter the array adding a property for image_id to each term object. This may be easier to understand for some people. Thoughts?

$term_s = apply_filters( ‘taxonomy-images-get-terms’, ”,$t_args );
that returns an empty array as well, although the child terms have surely some images.

I did some investigating here … and you totally found a bug with this filter… sorry about that … It has to do with my function passing and array with a single values as the taxonomy arg of get_terms(). I thought that I tested this pretty throughly, but I guess not. Will fix soon for sure and then release a new version.

Best,
-Mike

To make a long story short. There is a bug in core:
