I have a post thumbnail set for standard posts (when an image is featured) but for image format posts I'd like to have a separate, dynamically resizing (i.e. image resizing in the functions php via add_image_size), thumbnail. I found this snippet from the codex:
if ( has_post_format( 'video' )) {
echo 'this is the video format';
}
I've tried using it on my index.php with 0 success. Am I on the right track or should I be doing something completely different?
From your comment:
This is all I meant:
add_image_size( 'index-thumb', 640, 250, true ); add_image_size( 'image-format', 630, 9999, true );
So, let's assume you create custom image sizes for gallery and video (as well as a "default" size, which we'll call standard), perhaps like so:
<?php
add_image_size( 'index-standard', 640, 250, true );
add_image_size( 'image-gallery', 630, 9999, true );
add_image_size( 'image-video', 700, 9999, true );
?>
Now, in your template, where you want to output the custom image size, let's figure out which one to use, via get_post_format(), like so:
<?php
// Determine post format
$post_format = ( get_post_format() ? get_post_format() : 'standard' );
// Set image size based on post format
$thumbnail_size = 'image-' . $post_format;
// Output post thumbnail
the_post_thumbnail( $thumbnail_size );
?>
That should be it.
Note: By using get_post_format(), all you have to do is register the image size for each supported format, and you're done. You can use has_post_format(), but you'd have to add explicit code for each supported format, like so:
<?php
$thumbnail_size = 'image-standard';
if ( has_post_format( 'gallery' ) ) {
$thumbnail_size = 'image-gallery';
} else if ( has_post_format( 'video' ) ) {
$thumbnail_size = 'image-video';
}
the_post_thumbnail( $thumbnail_size );
?>
You could also use a switch instead of an if/else; either way, it's more efficient to use the get_post_format() method, above.
IF there's a post format (?) THEN return the format to the variable, otherwise (ELSE :) return the string 'standard'. So the syntax is basically (condition) ? true : else

Your comments on the question lead me to believe that you are having trouble outputting the content correctly. You said you're echoing the output; try to return it instead:
if ( has_post_format( 'video' )) {
$content = 'this is the video format';
}
return $content;
This may work if your content from this script is being output "before" the main post output, but instead you want it "inside" the main post output.
See append_content help for further discussion which might be helpful.
