Hi, I got a html that will accept user image file input, then when user click a button which will trigger a php to process that image file.
<input type="file" id='imgfile' class='adlist-input'> i want to validate that image file against their size/width/height/ file type etc, so once pass it validation, will save it to the server. my question is...any how to validate it from client-side 1st? in that way will react quickly to end-user in case any of validation are failed. so i am wondering it is possible or not? or only can validate it from server-side ( when call php programe )? thanks for any help/Davis.
