Hi @somosgrow
I’m glad I could help!
I gave it a shot and came up with updated version that will support setting different size limits per upload field, as well as a “fallback” size.
I’ve updated my gist so you’ll find full new code at the same link here
https://gist.github.com/adczk/f4916c36188039efe6b1580061041189
Once you update code on the site you’ll also need to adjust configuration again as this configuration code block has changed slightly:
## CONFIG ##
$form_ids = array( 3010, 123 ); // form IDs - one or more; if more - separate numbers with commas
$fields_ids = array( 'upload-1', 'upload-2', 'upload-3' ); // IDs of fields to check, one or more, if more - separate with commas
// max image sizes per each upload field (note no comma after last upload field line
// if size not defined here but field defined in $fields_ids, a "fallback" value below
// will be used
$max_sizes = array(
'upload-1' => array( 'width'=>500, 'height'=>500 ),
'upload-2' => array( 'width'=>150, 'height' => 200 )
);
// fallback sizes, if not defined per field above
$max_width = 20; // max image width in px - fallback if not defined per field
$max_height = 50; // max image height in px - fallback if not defined per field
$err_msg = 'Maximum image width/height: [wdt] x [hdt]!'; // custom error message for width/height; [wdt] and [hdt] will be replaced with max width/height accordingly.
$no_image_msg = 'Error fetching image sizes!'; // other error e.g. if it's not image file or doesn't exist due to upload issues
## END OF CONFIG; DO NOT EDIT BELOW ##
It’s similar but important changes are:
1. you now define default sizes here
// fallback sizes, if not defined per field above
$max_width = 20; // max image width in px - fallback if not defined per field
$max_height = 50; // max image height in px - fallback if not defined per field
They will be applied to fields that are listed in $fields_ids but don’t have individual sizes defined in $max_sizes.
2. here you define “per field” individual limits
$max_sizes = array(
'upload-1' => array( 'width'=>500, 'height'=>500 ),
'upload-2' => array( 'width'=>150, 'height' => 200 )
);
Note, fields here must still be defined in $fields_ids. I mean – if field is listed here but not in fields_ids, size restriction will not be applied. If field is listed in fields_ids but doesn’t have size defined here, the default “fallback” size limit will be applied to it. I hope it makes sense.
3. and now in your error message here
$err_msg = 'Maximum image width/height: [wdt] x [hdt]!'
if you use those [wdt] and [hdt] placeholders (including square brackets!) they’ll be automatically replaced with actual maximum width/height allowed for particular upload field.
I hope that this together with comments in the code is clear enough so you’ll be able to set it up but in case you’d have any additional questions, let us know (note though: if it comes to code extension, that’s as far as we can go with it).
Best regards,
Adam
