If you want to use jQuery’s validate
to check the size of the file you can by creating this method:
$.validator.addMethod('filesize', function(value, element, param) {
// param = size (en bytes)
// element = element to validate (<input>)
// value = value of the element (file name)
return this.optional(element) || (element.files[0].size <= param)
});
You would use it:
$('#formid').validate({
rules: { inputimage: { required: true, accept: "png|jpe?g|gif", filesize: 1048576 }},
messages: { inputimage: "File must be JPG, GIF or PNG, less than 1MB" }
});
