Insert into Post button missing for some picture

I have had the same problem even though I’m the only one uploading images.

I found that a code snippet in wp-admin/includes/media.php looks a bit strange…

I changed

if ( $send )
                $send = "<input type='submit' class='button' name='send[$attachment_id]' value='" . esc_attr__( 'Insert into Post' ) . "' />";

to

if ( ! $send )
                $send = "<input type='submit' class='button' name='send[$attachment_id]' value='" . esc_attr__( 'Insert into Post' ) . "' />";

And it started working again.

Not sure if this is the correct way to go though…

thank you johanl for your answer, great finding!

I’ll try that, even if I hope to get a cleaner solution since changing wp core files will cause to lose those changes everytime wordpress is updated.

this works for me!

I’m also having a problem with the this button not showing up, is it possible to fix without editing the core files?

I ran into problems by negating $send, instead I had to remove the condition altogether.

if ( $send )

You can force this to be on without hacking the core:

add_filter( 'get_media_item_args', 'force_send' );
function force_send($args){
	$args['send'] = true;
	return $args;
}
