image size validation

[sharma.atul85]

hello friends is there a way to restrict image size to a specific dimension like 800X1200.

like at the time when admin upload an image for product then an error image is displayed saying this size of image is not supported .

This is basically needed because am using code to resize image to three different sizes and resizing does not work properly when image size is greater than 1200X1200.

You can check the image size after it's uploaded with some code like this:

 

  if ( $image_size = @getimagesize( [color="#FF0000"][b]INSERT_PATH_TO_IMAGE_HERE[/b][/color] ) ) {
   if ( ( (int)$image_size[0] > 1200 ) || ( (int)$image_size[1] > 1200 ) ) {
     echo 'Image too large!';
   }
 }

ok well this code might work but it will check image height width after submitting ..isn't there any other code which displays error the time image is uploaded like thru ajax

There is no practical way to check the image size until AFTER it's uploaded.

 

That would require "client side" code (some sort of active-x code) to be installed on the PC uploading the image. That's how a lot of infections are spread so most people who know anything at all about how things work would just "click off" and never return (I would as well to some site that wants me to install an active-x control - I wasn't born yesterday :huh: ).

 

Stick with the "server side" approach.

 

You and your customers will both be happier.
