我的html中有许多下拉列表,我想从数据库中的某个下拉列表中发送每个值(我打开了该下拉列表,并选择了应该使用该下拉名称的任何值)。
数据库将这样显示,该用户从“ ABC下拉菜单”中选择了值1,从“ XYZ”下拉菜单中选择了值3,依此类推,而那些我没有选择的下拉菜单不应进入数据库。

为什么不使用不同的名称而不是完全相同的名称。
Report1, Printer1
Report2, Printer2
Report3, Printer3
在控制器中,您可以通过名称来捕获它们...
<table>
<tr class="evenrow">
<td align="center"><input type="hidden" name="report_id1" id="report_id" value="1">1</td>
<td>Customer Balances</td>
<td>
<select name="printer1" id="printer" class="form-control" title="">
<option value="">Browser Support</option>
<option value="1">Text</option>
<option value="2">Text</option>
<option value="3">Text</option>
</select>
</td>
</tr>
<tr class="evenrow">
<td align="center"><input type="hidden" name="report_id2" id="report_id" value="2">2</td>
<td>Customer Balances</td>
<td>
<select name="printer2" id="printer" class="form-control" title="">
<option value="">Browser Support</option>
<option value="1">Text</option>
<option value="2">Text</option>
<option value="3">Text</option>
</select>
</td>
</tr>
</table>
然后在控制器中:
$report1 = $this->input->post('report1');
$report2 = $this->input->post('report2');
$printer1= $this->input->post('printer1');
$printer2= $this->input->post('printer2');

您使用数组作为选择框名称,并且所有三个选择框都具有相同的名称,因此,如果要存储所有不同的节值,请更改选择框名称,以便在控制器中获得2个不同的数组,或者可以轻松地从哪个节中识别它有一个客户json
$selected_option= array("section1"=>$this->input->post('printer1',"section2"=>$this->input->post('printer2');
$selected_option_json= json_encode($selected_option);
将$ selected_option_json(带有json字符串)存储在db
希望它对您有帮助。
