php - PHP 用 1 个按钮提交多个表单

问题描述

我想提交多个表单，在所有表单之外只有 1 个按钮。这是 index.php

 <form id="allform" class = "NameInput" action="addToCartFood.php" method="POST">
            Name:   <input type="text" class = "inputName" name="Name" value=""><br>
 </form>

 <form id="allform" action="addToCartFood.php"  method="POST">
            Date:       
            <select name="Date" class = "Date">
                <option value="26">26</option>
                <option value="27">27</option>
                <option value="28">28</option>
            </select>
            July 2020
</form>
<form id="allform" action="addToCartFood.php" method="POST">
            Adult:      
            <select id = "selectboxAdult" name="Adult" class = "Adult" onchange = "calculateAll(<?php echo $_SESSION['price'];?>)">
                <option value="1">1</option>
                <option value="2">2</option>
                <option value="3">3</option>
                <option value="4">4</option>
            </select>
</form>

<input  type="submit" class = "submitbtn" form="allform" value="Add to Cart">

当我单击按钮时，它将转到 addToCartFood.php，这些是代码

$_SESSION['Date'] = $_POST['Date'];
$_SESSION['Name'] = $_POST['Name'];
$_SESSION['AdultQ'] = $_POST['Adult'];
$_SESSION['KidsQ'] = $_POST['Kids'];
$_SESSION['telnum'] = $_POST['telnum'];
$_SESSION['comment'] = $_POST['comment'];

先感谢您

解决方案

为什么有多种形式？只需将它们全部合并为一种形式，因为动作和方法对所有人都是相同的

<form id="allform" class = "NameInput" action="addToCartFood.php" method="POST">
            Name:   <input type="text" class = "inputName" name="Name" value=""><br>
            Date:       
            <select name="Date" class = "Date">
                <option value="26">26</option>
                <option value="27">27</option>
                <option value="28">28</option>
            </select>
            July 2020
            Adult:      
            <select id = "selectboxAdult" name="Adult" class = "Adult" onchange = "calculateAll(<?php echo $_SESSION['price'];?>)">
                <option value="1">1</option>
                <option value="2">2</option>
                <option value="3">3</option>
                <option value="4">4</option>
            </select>

<input  type="submit" class = "submitbtn" form="allform" value="Add to Cart">

</form>
