You might be wondering why you cannot post the values of some fields even it’s inside the form.
Having a form within a form in your html code/dom is a BIG issue when it comes to ie.
Some of the issues you will encouter are listed below:
1. You won’t be able to post the values of those fields and it’s not even on the $_POST coz basically those fields within nested form is not recognize.
2. When calling javascript those fields are undefined.
I read from another source that it has something to do with the DOM in ie. So in order to solve this issue fix your form. Remove the nested form in your html code.
