My Controller is:

        $post = $this->input->post(NULL,TRUE);
        $count=count($this->input->post('pro_id'));

        for($i = 0; $i < $count; $i++){
            $post []= array(
                'pro_id'        => $post['pro_id'][$i],

Change your controller as following code,

public function store_payment()
{
    $post = array();
        $post = $this->input->post(NULL,TRUE);
        $count=count($this->input->post('pro_id'));
        echo CI_VERSION;

        for($i = 0; $i < $count; $i++){
            $post = array(
                'pro_id'        => $post['pro_id'][$i],
                'date_add'      => $post['date_add'][$i], 
                'category'      => $post['category'][$i], 
                'type'          => $post['type'][$i], 
                'size'          => $post['size'][$i], 
                'counts'        => $post['counts'][$i], 
                'booking'       => $post['booking'][$i], 
                'confirmation'  => $post['confirmation'][$i], 
                'confirm_days'  => $post['confirm_days'][$i], 
                'allocation'    => $post['allocation'][$i], 
                'allocate_days' => $post['allocate_days'][$i], 
                'm_installment' => $post['m_installment'][$i], 
                'month'         => $post['month'][$i], 
                'y_instalment'  => $post['y_instalment'][$i], 
                'halfyear'      => $post['halfyear'][$i], 
                'leveling'      => $post['leveling'][$i], 
                'demarcation'   => $post['demarcation'][$i], 
                'possession'    => $post['possession'][$i]
                );
        }
    $this->projects->add_payment($post);
}

You used $post for two purpose, change your controller codes as following code:

public function store_payment()
{
    $post = $this->input->post(NULL,TRUE);
    $count=count($this->input->post('pro_id'));
    echo CI_VERSION;

    $data = array();
    for($i = 0; $i < $count; $i++){
        $data []= array(
            'pro_id'        => $post['pro_id'][$i],
            'date_add'      => $post['date_add'][$i], 
            'category'      => $post['category'][$i], 
            'type'          => $post['type'][$i], 
            'size'          => $post['size'][$i], 
            'counts'        => $post['counts'][$i], 
            'booking'       => $post['booking'][$i], 
            'confirmation'  => $post['confirmation'][$i], 
            'confirm_days'  => $post['confirm_days'][$i], 
            'allocation'    => $post['allocation'][$i], 
            'allocate_days' => $post['allocate_days'][$i], 
            'm_installment' => $post['m_installment'][$i], 
            'month'         => $post['month'][$i], 
            'y_instalment'  => $post['y_instalment'][$i], 
            'halfyear'      => $post['halfyear'][$i], 
            'leveling'      => $post['leveling'][$i], 
            'demarcation'   => $post['demarcation'][$i], 
            'possession'    => $post['possession'][$i]
            );
    }
    $this->projects->add_payment($data);
}
