Couple style changes i needed for various reasons and dropped the locally included jquery and using one on the jquery cdn
Changed the encoding of the fields before they're subitted to encodeURIComponent instead of encodeURI ,  it wsa causing a problem like say you submitted something with a + in it, it was at times getting changed to a space ...
php notice fixs
More PHP Notice fixs..  also added using placeholders for some of the fields, it adds a veyr nice visual look
