Different sizes for front-end submissions (such as via Gravity Forms)?

Hi Jason,
The upload conditions are infinitely extendable via this filter:
apply_filters( 'imsanity_get_max_width_height', array( $w, $h ), $source );

From there, you can pick whatever conditions you like, and return the dimensions as an array, like so:
return array( 1920, 1080 );

If you want to use $source variable in your conditions, it is a numerical value:
1 = uploaded to a post
2 = uploaded to the library
4 = anywhere else

Thanks for the quick reply.

Unfortunately, what I learned by trying to do this is that Gravity Forms file uploads don’t actually get processed by Imsanity at ALL, so this filter doesn’t do anything. :/

Cheers

Is there a function available via Imsanity that I can pass a file path to, along with dimensions, to do the resizing?

like, imsanity_resize_file( $path_to_file, $max_dimensions_array )?

thanks!

EDIT: I found imsanity_image_resize. I’ll try making gravity forms call that after uploading. thanks!

Yup, you can use that one or imsanity_handle_upload( $params ) where $params is an array like so:

array(
    'file' = '/the/full/path/to/an/image.jpg',
    'type' = 'image/jpeg',
);

But imsanity_image_resize() is probably easier for your use, and it’s what imsanity_handle_upload() ends up calling anyway ??

I’m getting around to trying this out, and unfortunately I don’t think it does exactly what I want.

I was hoping I could simply resize the file in place; just overwrite the file in the existing filepath with a smaller version. But it looks like imsanity_image_resize explicitly forbids this.

// Make sure that the destination file does not exist.
if ( file_exists( $dest_file ) ) {
$dest_file = $editor->generate_filename( ‘TMP’, $dest_path );
}

Any ideas? and is it possible I’m just greatly overthinking / overcomplicating this?

Cheers mate

Yeah, if you use imsanity_image_resize() directly, then you need to check the filesize afterwards and then overwrite the original.
Basically doing this portion of imsanity_handle_upload():

$resizeresult = imsanity_image_resize( $oldpath, $neww, $newh, false, null, null, 82 );
if ( $resizeresult && ! is_wp_error( $resizeresult ) ) {
	$newpath = $resizeresult;
	if ( is_file( $newpath ) && filesize( $newpath ) < filesize( $oldpath ) ) {
		// we saved some file space. remove original and replace with resized image.
		unlink( $oldpath );
		rename( $newpath, $oldpath );
	} elseif ( is_file( $newpath ) ) {
		// the resized image is actually bigger in filesize (most likely due to jpg quality).
		// keep the old one and just get rid of the resized image.
		unlink( $newpath );
	}
}
