Question

我是PHP新手，花了10个小时试图解决这个问题。

目标是将所有数据输入此订单表单，并通过PHP将其发送到我的电子邮箱。

我有两个问题：

1. 我可以让PHP从单个菜单项中发送数据（例如：Mexican Tortas），但是如何让PHP从多个项目中发送数据（例如：Mexican Tortas，Fish）三明治和汉堡包？）

2. 如何告诉PHP不要从没有“多少？”的菜单项中发送数据。还是“自定义它？”文本字段填写完毕？

如果你能提供一个超级简单的例子（或学习资源的链接），我将非常感激。

谢谢你，亚比雅

PHP

<?php
if(isset($_POST['submit'])) {

$to = "test@mywebsite.com"; 
$subject = "New Order";
$name_field = $_POST['name'];
$phone_field = $_POST['phone'];
$item = $_POST['item'];
$quantity = $_POST['quantity'];
$customize = $_POST['customize'];

}

$body = "Name: $name_field\nPhone: $phone_field\n\nItem: $item\nQuantity: $quantity\nCustomize: $customize";

echo "Data has been submitted to $to!";
mail($to, $subject, $body);

?>

Answer 1

我建议你使用'[]'，因为它将多个输入字段组合成一个数组。

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
  $_POST = filter_input_array(INPUT_POST, FILTER_SANITIZE_SPECIAL_CHARS);

  $to = "test@mywebsite.com"; 
  $subject = "New Order";

  $order = array();
  $order['name']  = $_POST['name'];
  $order['phone'] = $_POST['phone'];

  $food = $_POST['food'];

  foreach ($food as $type => $value)
    if (strlen($value['quantity']) > 0) // assuming 'customize' is optional
      $order[$type] = $value;

  print_r($order);
}

?>

<html>
<head>
  <title>Order now!</title>
  <style>label,input,textarea {display:block}</style>
<body>
<?php // You need enctype for '[]' support' ?>
<form action="" method="post" enctype="multipart/form-data">
  <div class ="item">
    <label>Mexican Torta - $8.50</label>

    <b>How Many?</b> 
    <input name="food[mexican_torta][quantity]" type="text">

    <b>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></b> 
    <textarea name="food[mexican_torta][customize]"></textarea>
  </div>

  <div class ="item">
    <label>Fish - $3.50</label>

    <b>How Many?</b> 
    <input name="food[fish][quantity]" type="text">

    <b>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></b> 
    <textarea name="food[fish][customize]"></textarea>
  </div>

  <h2>Place Your Order Now:</h2>

  <em>Fill in the form below, and we'll call you when your food is ready to be picked up.</em>

  <label>Enter your name</label>
  <input type="text" name="name">

  <label>Enter your phone nr.</label>
  <input type="text" name="phone">

  <button>Submit</button>
</form>
</body>

用户提交（例如我将鱼留空）你得到了

Array ( 
 [name] => Fab 
 [phone] => 1212
 [mexican_torta] => Array ( [quantity] => 2 [customize] => Test ) 
)

使用'[]'稍微玩一下，以获得您真正想要的数组输出。 print_r将准确显示您获得的内容。从这里可以很容易地将食物细节放在电子邮件中

Answer 2

您需要唯一的表单字段名称。换句话说，您不能重复以下形式的项目：

<input name="quantity" type="text"/>

相反，您需要唯一的名称，例如：

<input name="quantity_fish" type="text"/>

然后，您可以使用PHP来解析$ _POST，如果您愿意，可以抛出空字段。
