我需要一些帮助,在“购物车”数组中存储订单<form>
。我无法让它发挥作用。
请参阅下面的代码。
PHP:
session_start();
## make sure cart exists
if ( ! isset($_SESSION['cart'])) {
$_SESSION['cart'] = array();
}
## Add
if (isset($_POST['Submit']) && $_POST['Submit'] == 'add' ) {
$ticket = $_POST['courseID'];
add($ticket);
header('Location: book.php');
}
## Add to Cart
function add($ticket) {
$_SESSION['cart'][$ticket['courseID']] = $ticket;
$_SESSION['cart'][$ticket['courseID']]['bday'] = $_POST['day'];
$_SESSION['cart'][$ticket['courseID']]['btime'] = $_POST['time'];
$_SESSION['cart'][$ticket['courseID']]['badult'] = $_POST['as'];
$_SESSION['cart'][$ticket['courseID']]['bchild'] = $_POST['cs'];
return TRUE;
}
形式:
<h2><?php echo $_POST['title'];?></h2>
<form id="booking" onSubmit="return check_book()" method="post" action="#">
<!-- Course Name -->
<input type="hidden" name="courseID" id="cID" value="<?php echo $_POST['courseID'];?>"/>
<!-- Course Day -->
<input type="text" name="day" id="day" value="<?php echo $_POST['day'];?>" readonly/>
<!-- Course Time -->
<input type="text" name="time" id="time" value="<?php echo $_POST['time'];?>" readonly/>
<!-- Adult Spots -->
<select name="as" class="1-10">
<option value="" name="adult" disabled selected>Adult</option>
</select>
<input type="text" class="as_price" readonly/>
<!-- Child Spots -->
<select name="cs" class="1-10">
<option value="" name="child" disabled selected>Child</option>
</select>
<input type="text" class="cs_price" readonly/>
<!--Submit Button -->
<input type="submit" value="Add to Cart"/>
</form>
我也希望能够增加/减少门票,但我只是想让基础知识现在正常运作。
非常感谢任何帮助!

您正在检查是否存在$ _POST ['Submit'],但这不存在。
如果您检查表单,则没有任何名为“提交”的表单字段 - 您需要更改PHP逻辑而不是检查它,或者更改HTML表单以包含它:
<!--Add an extra hidden form field called 'Submit' with a value of add: -->
<input type="hidden" name='Submit' value="add"/>
