你好 friend ，我有一个表单字段，我想在其中插入数据，该字段有四个字段，分别是 customer_id 、 field_name1 、field_name2 、 field_name3 、 问题是我想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合作伙伴详细信息时，这些输入将由 javascript 显示。 像field_name1，field_name2，field_name3可以重复十次，我想根据具有相同customer_id但不同字段名称的数字在数据库中插入数据，下面是我的代码，希望你理解。
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";
}
}
}
?>

最佳答案
为重复字段指定数组样式名称:
<input type="text" name="field_name1[]">
PHP 会将输入收集到数组中，因此 $_POST['field_name1'] 将是一个数组。然后你可以循环它们:
foreach ($_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
}
