通过PHP提交数据的最简单方法？

I'm new to PHP, and have spent 10 hours trying to figure this problem out.

The goal is to take all data entered into this order form, and send it to my email via PHP.

I have 2 questions:

1. I can get PHP to send data from a single menu item (example: Mexican Tortas), but how do I get PHP to send data from multiple items (example: Mexican Tortas, Fish Sandwich and Hamburger)?

2. How do I tell PHP to not send data from menu items that don't have the "How Many?" or "Customize It?" text fields filled out?

If you could provide a super simple example (or a link to a learning resource) I would really appreciate it.

Thank you, Abijah

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
Phone: $phone_field

Item: $item
Quantity: $quantity
Customize: $customize";

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

?>

    I suggest you use '[]', as it groups multiple input fields to an array.

    <?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>

    User submits (for example I left the fish blank) and you get 

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

    Play around a bit with the '[]' to get the array output you really desire. The print_r will show you exactly what you get. From here it is really easy to put the food details in the e-mail
