Question

你好朋友，我有一个表单字段，我想在其中插入数据，该数据包含四个字段，分别是customer_id，field_name1，field_name2，field_name3，问题是我要插入具有许多输入但输入名称相同的数据，例如field_name1 field_name2 field_name3，首先没有输入，但是当我单击按钮添加伙伴详细信息时，这些输入将由javascript显示。像field_name1，field_name2，field_name3可以重复十次，我想根据其中具有相同customer_id的数字在数据库中插入数据，但是字段名称不同，下面是我的代码，希望您理解。

这是我的代码

    <?php
$conn=mysqli_connect("localhost","root","","satya");
if(isset($_POST['submit'])){
    $customer_id=$_POST['customer_id'];
for ($ix=0; $ix<count($_POST['field_name1']); $ix++)
{
    $field_data = array(
        'field_name1' => $_POST['field_name1'][$ix],
        'field_name2' => $_POST['field_name2'][$ix],
        'field_name3' => $_POST['field_name3'][$ix],

    );
    $sql="INSERT INTO customer(customer_id,details1,details2,details3) VALUES('$customer_id','$field_name1','$field_name1','$field_name1')";
    $result=mysqli_query($conn,$sql);
    if($result){
        echo "data has been inserted";
    }
    else{
        echo "data could not be inserted";
    }
}
}
 ?>

给出重复字段数组样式名称：

<input type="text" name="field_name1[]">

PHP将把输入收集到数组中，因此$_POST['field_name1']将是一个数组。然后，您可以遍历它们：

foreach ($_POST['field_name1'] AS $index => $field1) {
    $field2 = $_POST['field_name2'][$index];
    $field3 = $_POST['field_name3'][$index];

    // now you can insert all these values into the DB
}

如何将具有相同名称的许多Input数据插入数据库？
