Use featured image *or* post thumbnail

Dear peter-a

There was a mistake in https://upprev.com/documentation/action-reference/iworks_upprev_image

replace “return” to “echo”.

Marcin

Hi Marcin,

Thank you. I added this code to functions.php:

add_action( 'iworks_upprev_image' , 'default_image' );
function default_image()
{
    echo '<img src="image.png" alt="" />';
}

but still the posts that don’t have a featured image have no thumbnail in the upPrev box.

Peter

Please replace image.png to valid default image url.

Marcin

Hmm, I want to use the post thumbnail, which is different for each post. I tried this:

add_action( 'iworks_upprev_image' , 'default_image' );
function default_image()
{
    echo '<img src="'. get_the_post_thumbnail($page->ID, 'thumbnail') . '" alt="" />';
}

but I think it’s not formatted correctly, because it’s not working.

Hmm.. peter-a

upPrev use feature image and you do not need do anything else.

I do not understand why you try add feature image?

If this not working is probably some influence of other plugins or theme.

Marcin

Hi Marcin,

Yes, upPrev uses feature image. Feature image is working OK for upPrev.

On my site, some posts do not have a feature image.
But those posts have an image (a normal image). So WordPress creates a post thumbnail.

If the post has an image but does not have a featured image, I want upPrev to use the post thumbnail. (At this time it does not.)

“post thumbnail” functions use “feature image”.

If you have other method to create “icon for post” then you must use the same method in iworks_upprev_image.

add_action( 'iworks_upprev_image' , 'my_image' );
function my_image()
{
    echo '<img src="'. my_mothod_to_get_image() . '" alt="" />';
}

Function get_the_post_thumbnail() return “future image”. documentation says:

Gets the Featured Image (formerly called Post Thumbnail) as set in post’s or page’s edit screen and returns an HTML image element representing a Featured Image, if there is any, otherwise an empty string.
