将所选值从引导程序选择选择器发送到codeigniter中的Controller

Question

我在向codeigniter中的控制器发送selectpicker的值时遇到问题，任何人都可以告诉我如何获取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>
