Codeigniter:正在从名称[]中获取Select选项值

Question

希望修改现有系统，该系统添加了UOM下拉选择字段。我想把我选择的值拿到我的CodeIgnitor控制器，但它似乎不起作用。

<tbody id="dataTable" style="background: #cccccc ">
<tr>    
<!--<td><input type = "checkbox" name="chkbox[]"/></td>-->
<td></td>
<td><input required type="text" name="item[]"/></td>
<td><input required type="text"  name="price[]" /></td>
<td><input required type="text"  name="qty[]" /></td>
<td><select required type="text" name="uom[]">
<option value = "">--Please Select--</option>
<option value = "PCS">PCS - Pieces</option>
<option value = "M">M - Meters</option>
<option value = "KG">KG - Kilograms</option>
<option value = "BOX">BOX - Boxes</option>
<option value = "SET">SET - Sets</option>
<option value = "CTN">CTN - Cartons</option>
<option value = "PLT">PLT - Pallets</option>
<option value = "ROLL">ROLL - Rolls</option>
<option value = "PKT">PKT - Packets</option>
</select>
</td>  
</tr>

下面是我的控制器：

public function user_data_submit() {
$data = array(
//'tranh_item_uom' is my uom database's column
'tranh_item_uom'=>$this->input->post('uom1'),
'tranh_item_uom2'=>$this->input->post('uom2'),
'tranh_item_uom3'=>$this->input->post('uom3'),
'tranh_item_uom4'=>$this->input->post('uom4'),
'tranh_item_uom5'=>$this->input->post('uom5'),
);

}

运气不好，不能让它正常工作。很抱歉，我最近刚刚学习了codeignator和php，仍然不太熟悉。

要获得所有的uom[]输入，您可以像这样组成$data数组：

public function user_data_submit() {
$uoms = $this->input->post('uom');
$data = [];
foreach ($uoms as $key => $value) {
reset($uoms);
$i = $key;
if ($key === key($uoms)) {
$i = ''; // set first array item key as empty
}
$data[$key] = [
"tranh_item_uom$i" => $value
];
}

}
