Hi;
i am writting a form to let people submit
their information and upload an image.
My idea is if the user fill all the filed(name and age of the field) and upload an image, then i will submit the form.
if the user does not fill any of the field of the name and age, or do not upload an image, then the user fail to submit.
In this case, the user will refill the form again, and in the refilled in form, it will display the resized image that it have just uploaded and value the user just
filled.
My problem is i could not display the resized image i just upload in the filled form, if i failed to submit the form
(for example, i did not fill some filed i must fill it)
Could anyone help me,plase.
