I am using the file uploading class in codeigniter and can successfully upload images. My question is how to go about making sure the user uploads an image of only a fixed size, 600px by 360px, nothing more nothing less? I have tried using the upload data array to get the image height and width and am checking against these values TRUE or FALSE. If false, I pass an error string to the view, if true, I display nothing in the view, but I am not sure it is working right. Any one can help with how to go about doing this? Thank you in advance!
You can use GDI library tools to find out the image height and width, aswell as other information.
for example:
$imgInfo = getimagesize("/path/to/image.png");
if ($imgInfo[0] != 600) && $imgInfo[1] != 360){
throw new Exception("Illegal image size");
}
