如何显示所选选项的结果
提问于 2016-03-01 12:05:08
我有这个表单将添加所选项目的总成本，但我需要显示在结果中选择了什么。如何在result中显示选中的选项？我需要显示买家的确切订单，在一个表。
<!DOCTYPE html>
<head>
<title> Light Bulbs Sales Form </title>
</head>
<body>
<h2> Welcome to Light Bulbs Sales Form </h2>
<form action="index.php" method="post">
<p>
<label> Buyer's Name:
<input type="text" name="name" size="30" />
</label>
<p/>
<table>
<tr>
<th></th>
<th>Product Name</th>
<th>Price</th>
</tr>
<tr>
<td><input type="checkbox" name="b[]" value="2.39"/></td>
<td> Four 25-watt light bulbs </td>
<td> $2.39 </td>
</tr>
<tr>
<td><input type="checkbox" name="b[]" value="4.29"/></td>
<td> Eight 25-watt light bulbs </td>
<td> $4.29 </td>
</tr>
<tr>
<td><input type="checkbox" name="b[]" value="3.95"/></td>
<td> Four 25-watt long-life light bulbs </td>
<td> $3.95 </td>
</tr>
<tr>
<td><input type="checkbox" name="b[]" value="7.49"/></td>
<td> Eight 25-watt long-life light bulbs </td>
<td> $7.49 </td>
</tr>
</table>
<h3>Payment Method</h3>
<p>
<label><input type="radio" name="payment" value="Visa"/>Visa</label>
<br/>
<label><input type="radio" name="payment" value="Master Card"/>Master Card</label>
<br/>
<label><input type="radio" name="payment" value="Discover"/>Discover</label>
<br/>
</p>
<p>
<input type="submit" value="Submit Order"/>
<input type="reset" value="Clear Order Form"/>
</p>
</form>
</body>
</html>
这是我的php代码：
<?php
$name=$_POST["name"];
$bulbs=$_POST["b"];
$pmode=$_POST["payment"];
$total=0;
for($i=0;$i<sizeof($bulbs);$i++)
{
$tax=$bulbs[$i]*0.062;
$total=$total+$bulbs[$i]+$tax;
$totalcost=number_format((float)$total, 2, '.', '');
}
print "Your name is: $name <br>";
print "Your total cost is: $totalcost <br>";
print "Your chosen method of payment is: $pmode";
?>

根据你的选择进行转换。再试试这个。您可以按如下方式打印选定的选项值。
HTML和PHP：
<form action="php_checkbox.php" method="post">
<label class="heading">Select One:</label>
<input type="checkbox" name="check_list[]" value="4.29"><label>4.29</label>
<input type="checkbox" name="check_list[]" value="3.25"><label>3.25</label>
</form>
<?php
if(isset($_POST['submit'])){
if(!empty($_POST['check_list'])) {
$checked_count = count($_POST['check_list']);
echo "Selected values ".$checked_count." option(s): <br/>";
foreach($_POST['check_list'] as $selected) {
echo "<p>".$selected ."</p>";
}
else{
echo "<b>Please Select Atleast One Option.</b>";
}
}

使用内爆我们可以显示所选择的内容
$select_val=$_POST["b"];
$comma_separated = implode(",", $select_val);
echo $comma_separated ;array_sum将数组中的所有值相加，并显示总数
echo "total = " . array_sum($select_val) . "\n";页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
