How to add a class to an image within loop

[J KornMember Post count: 2]

Hey all,

I’m new to Genesis and still trying to find my way around all of the hooks and filters Genesis makes available.  I’m attempting to add a class to the image within a loop on a custom post archive page.  To do so, I was attempting to use genesis_get_image_default_args, however, that doesn’t seem to be working.

Here is the code I’m currently using:

function korndev_archive_image( $args ){
$args = array(
 'format' => 'html',
 'size' => 'full',
 'num' => 0,
 'attr' => array('class'=>'aligncenter'),
 'fallback' => 'first-attached',
 );
 return $args;
}
add_filter('genesis_get_image_default_args','korndev_archive_image');

Am I doing something wrong?  Missing something?  Any help would be greatly appreciated!

Thanks!

Are you using your own custom loop/query or using genesis_custom_loop to loop through your posts?

You might take a look at image.php in the Genesis theme to see how it’s handling images. Looks like genesis_get_image_default_args is called in the genesis_get_image function, which uses wp_get_attachment_image (See how style classes are passed to this last function in the codex: http://codex.wordpress.org/Function_Reference/wp_get_attachment_image)

I’m trying to be helpful and not send you off following rabbits. If that doesn’t get you going in the right direction, maybe you can post the entire contents of your archive page so I can see your function in context.

Cheers,

Carrie

Thanks for the response, Carrie.

Are you using your own custom loop/query or using genesis_custom_loop to loop through your posts?

No.  I’m using a template, archive-customtype.php, and within that, just trying to filter the image to add in/modify the class. I was looking through the Genesis code, specifically the image.php file and saw the following within genesis_get_image:

$defaults = apply_filters( 'genesis_get_image_default_args', array(
 'format' => 'html',
 'size' => 'full',
 'num' => 0,
 'attr' => '',
 'fallback' => 'first-attached',
 ) );

So, I assumed I could filter the genesis_get_image_default_args, however, my code above seems to have no effect.  I’ve found another way around what I was trying to do, but seems like using genesis_get_image_default_args would have made more sense.

For your reference, here is what my archive template looked like before (pretty straight forward):

remove_action( 'genesis_before_post_content', 'genesis_post_info' ); // Remove post info
remove_action( 'genesis_after_post_content', 'genesis_post_meta' ); // Remove post meta
add_filter( 'genesis_get_image_default_args', 'korndev_archive_image'); // Modify image


function korndev_archive_image( $args ){
 $args = array( 'attr' => array('class'=>'aligncenter') );
 return $args;
}
genesis();

Thanks!

Check out this thread:

Maybe you could use a CSS hack until the fix is included in 2.0? You could add a body class to your archive template to be able to specifically target just that page with your CSS (Here’s a good article on body classes: http://designsbynickthegeek.com/tutorials/dynamic-body-classes).

Keep me posted.
