codeigniter form not submitting fields

Question

I'm a newbie for codeigniter. I'm stuck at a problem, that my form is not posting values, I dont know why. Current site works fine on local server and my testing server. As I transferred complete site on clients server, this problem occurred.

I have checked, htaccess is enabled. I'm also pasting my view, and controller. Please help me

VIEW
