控制器：
public function get_songs(){
$top1=$this->input->get_post('drptop1');
$top2=$this->input->get_post('drptop2');
$top3=$this->input->get_post('drptop3');
$top4=$this->input->get_post('drptop4');
$top5=$this->input->get_post('drptop5');
$new1=$this->input->get_post('drptop6');
$new2=$this->input->get_post('drptop7');
$new3=$this->input->get_post('drptop8');
$new4=$this->input->get_post('drptop9');
$new5=$this->input->get_post('drptop10');
die(var_dump($top1));
//$this ->rbt->update_all_songs($top1,$top2,$top3,$top4,$top5,$new1,$new2,$new3,$new4,$new5);
}
在那之后，它总是说bool(false). =.=
你正在bool(false)，因为$top 1中没有值。
其次，表单中的输入名称与您用于获取值的变量名称不同。
Example:
<select name="drptop_1" id="drptop_1" class="form-control m-b"></select>
AND
$top1=$this->input->get_post('drptop1');
尝试使用相同的输入名称name="drptop_1"和 php 变量名称get_post('drptop1')希望这是有帮助的。
