I am using the image.module 4.7.x to have images posted on my site. If a user uploads an image with the image.module that is larger than my php.ini settings (currently 2mb) I get the warning:

The selected file /var/www/files could not be copied.

Subsequently, within my /files/images/ folder this creates files, files_0, files_1, etc... with 0kb file sizes.

Also, a new node is created with just a title (and any body text if it was entered), but no image.

I would like to check the file to be uploaded and if it is larger than my max file size limit I would like to throw an error to the user letting them know the image needs to be scaled down. Also, I don't want a node created if the file size is too large.

I entered this code within the image.module after line 156 without any luck:

// check to see if the file size is less than php.ini max limit
if (filesize($file->filepath) / 1000000 > 2 ) {
//the number "2" is for the number of megabytes
form_set_error($field_name, t('The uploaded image is too large Scale it down under 2 megabytes'));
return;
}

Has anybody got something similar working???

Perhaps I should use the hook_validate function within image.module. Not sure how I could do this.

Here's what I have been trying without hook_validate. I'm able to pull the current php.ini max_upload_size using:

$uploadsize = file_upload_max_size($file) * 1000000;

Now i need to somehow pull the uploaded image's filesize, but I'm having trouble. Here's what I've tried:

$filesize = image_get_info($file->file_size);

So then I would do:

	  if($filesize > $uploadsize) {
  	  form_set_error($field_name, t('Uploaded file is too large scale it down under $uploadsize'));
  	  return;
  	  }

Does anybody know how to validate the uploaded image and pull it's filesize?

Hi v1nce. I've got this exact same problem. It's hard to believe nobody else seems to have a problem with this. Anyway, did you find an answer?

there is an enhanced scaling module available in the downloads area that should solve this type of problem.

have a look at the image enhanced scaling module

with it you should be able to scale images down automatically after they are uploaded so that you never have empty image files.

I patched the image module with the below:

line 70: 

<?php
$form['image_max_upload_size'] = array('#type' => 'textfield', '#title' => t('Maximum upload size'), '#default_value' => variable_get('image_max_upload_size', 800), '#size' => 12, '#description' => t('Maximum size of uploads per file, in kilobytes'));
?>

line 156-162

<?php
 	  // start code patch to image module and add max file size limit
	  if ($file->filesize > variable_get('image_max_upload_size', 800) * 1024) {
        form_set_error($field_name, t('The image you uploaded was too big. You are only allowed to upload files less than %max_size but your file was %file_size.', array('%max_size' => format_size(variable_get('image_max_upload_size', 800) * 1024), '%file_size' => format_size($file->filesize))));
        file_delete($file->filepath);
        return;
      }
?>
