如何在php codeigniter中將動態生成的表數據保存到mysql數據庫

Question

我在PHP代碼點火器中創建了一個Web應用程序，它生成包含員工收入，扣除計算的表。 因為我是CI的新手。 我試圖將動態生成的表數據保存到數據庫，但失敗了。 我沒有得到如何將表數據POST到Controller。 歡迎任何幫助。

function index()
{

    if($this->input->post("submit"))
    {
         $vals=$this->cpanel_model->esic();
     if($vals){
        $data['w_share']=$vals->w_share;
        $data['e_share']=$vals->e_share;
     }

    $data["wshare"]="";
        //echo $data['w_share'];
        $city=$_POST["city"];
        $v1= $data['w_share'];
        $v2= '100';
        $v3= $data['e_share'];
        $arr=$_POST["wid"];
        $arr1=$_POST["days"];
        $arr2=$_POST["payment"];
        $arr3=$_POST["wdays"];
        for ($i=0; $i <count($arr1) ; $i++)
         { 
            $net[$i]=($arr2[$i]/$arr3[$i])*$arr1[$i];

            $wshare[$i]=($net[$i]/$v2)*$v1;
            $eshare[$i]=($net[$i]/$v2)*$v3;
            $total[$i]=$eshare[$i]+$wshare[$i];
            $wdays[$i]=$arr3;
            $days[$i]=$arr1;
         }
         $data["net"]=$net;
         $data["wshare"]=$wshare;
         $data["total"]=$total;
         $data["eshare"]=$eshare;
         $data["wdays"]=$arr3;
         $data["days"]=$arr1;
         $data["list"]=$this->payment_model->search($city);
         $this->load->view("secure/php-version/esic",$data);

    }

  <?php echo form_open('esic/insert',array("role"=>"form")); ?>

它不太清楚你當前如何生成表格，但無論如何，當你生成表格時，你必須將它放在一個表格中，並為輸入分配鍵。 試試這種方法：

HTML（這些是生成表時應該得到的結果）

<form action="<?= base_url() ?>table_data" method="post">
    <table>
        <thead>
            <tr>
                <th>Name</th>
                <th>Earnings</th>
                <th>Deduction</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td><input type="hidden" name="table[0][name]" value="name1">name1</td>
                <td><input type="hidden" name="table[0][earning]" value="earning1">earning1</td>
                <td><input type="hidden" name="table[0][deduc]" value="deduc1">deduc1</td>
            </tr>
            <tr>
                <td><input type="hidden" name="table[1][name]" value="name1">name1</td>
                <td><input type="hidden" name="table[1][earning]" value="earning1">earning1</td>
                <td><input type="hidden" name="table[1][deduc]" value="deduc1">deduc1</td>
            </tr>
        </tbody>
    </table>
    <input type="submit" value="Submit this table">
</form>

控制器：

function table_data() {
    if ($this->input->post()) {
        $table_data = $this->input->post('table');
        $this->load->model('model_name');
        $this->model_name->insert_table_data($table_data);
    }
}

模型：

function insert_table_data($table_data){
    $this->db->insert_batch('mytable', $table_data); 
}
