Question

在这里，我有一些案例，我认为这对我来说是独一无二的。这个问题，我想循环一些标签 3次。循环是工作，但当它输入到数据库... 只有一个循环有效。

这里有截图，

<td>
    <label for="baris">Baris</label>
    <select name="baris">
        <option value="">--</option>
        <?php 
            for ($i2=A; $i2 < F; $i2++) { 
                echo "<option name='".$i2."'>".$i2."</option>";
            }
         ?>
    </select>
</td>
<td>
    <label for="kolom">Kolom</label>
    <select name="kolom">
        <?php 
            for ($i3=1; $i3 <= 10; $i3++) { 
                echo '<option name="'.$i3.'">'.$i3.'</option>';
            }
         ?>
    </select>
</td>

此输入数据库的代码

<?php     
                if(isset($_POST['masukan'])){
                    $nama = htmlspecialchars($_POST['nama']);
                    $email = htmlspecialchars($_POST['email']);
                    $jk = htmlspecialchars($_POST['jk']);
                    $notlp = htmlspecialchars($_POST['notlp']);

                    $queryinput = mysqli_query($link, "UPDATE tb_customer 
                                                        SET nama='$nama',
                                                            email='$email',
                                                            notlp='$notlp',
                                                            jk='$jk'

                                                        WHERE id_cust='$id_cust1'    
                                                        ");

                    $querytampil = mysqli_query($link, "SELECT * FROM tb_customer WHERE id_cust ORDER by id_cust desc limit 1");
                    $dcus = mysqli_fetch_assoc($querytampil);
                    $id_cust = $dcus['id_cust'];

                    $querytampil2 = mysqli_query($link, "SELECT max(num_ticket)AS num  FROM tb_ticket");
                    $dnumti = mysqli_fetch_assoc($querytampil2);
                    $num_ticket = $dnumti['num'];
                    $hasil = $num_ticket + 1;

                    for ($i5= 1; $i5 <= $p; $i5++) { 

                    $baris = htmlspecialchars($_POST['baris']);
                    $kolom = htmlspecialchars($_POST['kolom']);
                        if($queryinput){
                            $id_flight = $data['id_flight'];
                            $queryinput2 = mysqli_query($link, "INSERT INTO tb_ticket VALUES('','$id_cust','$id_flight','$hasil','','','','','$id_dest','$id_ori', '$baris', '$kolom')");

                            if ($queryinput2) {
                                $querytampil3 = mysqli_query($link, "SELECT * FROM tb_ticket order by num_ticket desc limit 1");
                                $dtick = mysqli_fetch_assoc($querytampil3);
                                $nt = $dtick['num_ticket'];
                                echo "<script>alert('Succes.')</script>";
                                echo '<script>window.location="pembayaran.php?num_ticket='.$nt.'&&id_cust='.$id_cust.'"</script>';
                            }else{

如果我说得对;这是因为你没有将你的html变量设置为数组。

您需要进行的第一项更改位于您的视图页面中。

<select name="baris"> - ＆gt; <select name="baris[]">

<select name="kolom"> - ＆gt; <select name="kolom[]">

这会将您的$_POST['baris']和$_POST['kolom']设置为数组。

因为你已经在循环......

for ($i5= 1; $i5 <= $p; $i5++) { 
    $baris = htmlspecialchars($_POST['baris']);
    $kolom = htmlspecialchars($_POST['kolom']);

这个东西现在需要访问相关的数组......并且变成......

for ($i5= 1; $i5 <= $p; $i5++) { 
    $baris = htmlspecialchars($_POST['baris'][$i5]);
    $kolom = htmlspecialchars($_POST['kolom'][$i5]);

想为标签<option> </option>
