twitter-bootstrap - 将引导选择选择器中的选定值发送到 codeigniter 中的控制器

Question

我在将 selectpicker 的值发送到 codeigniter 中的控制器时遇到问题，谁能告诉我如何获取 selectpicker 的选定值并将其传递给控制器​​以进行进一步处理。

这是我的代码：-

<!--    <form action="" method="POST">  -->
                <?php $data = array(
                    'id'=>'inventory_form', 
                    ); ?>
                <?php  echo form_open('main/store',$data); ?>
               <div class="table-responsive">
                    <table class="table table-bordered table-hover" id="inv_tbl">
                        <thead>
                            <th>No</th>
                            <th>~</th>
                            <th>Barcode</th>
                            <th>Product Name</th>
                            <th>SM</th>
                            <th>SPL</th>
                            <th>Quantity</th>

                            <th>Amount</th>
                            <th><input type="button" value="+" id="add" class="btn btn-primary add_inv_row"></th>
                        </thead>
