我编写的以下程序PHP要求用户选择他们熟悉的语言,并在同一页面中显示所选语言。如果用户没有选择任何语言,我可以显示错误消息。但我需要显示所选的复选框项目,即在同一页面本身中的语言。 示例:您认识的语言是英语,法语。 有人可以帮忙吗?
<?php
$languages_error = $languages_result = $languages_list = "";
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
if(empty($_POST["languages"])){
$languages_error = "*Select the languages which you know";
}
else
{
$languages_result = "Languages selected are";
}
}
?>
<!DOCTYPE html>
<html>
<head>
<title>Check Box Page</title>
</head>
<body>
<div id="contact">
<h1>What languages do you know?</h1><br>
<form action="checkbox.php" method="post">
<fieldset>
<input type="checkbox" name="languages[]" id="languages" value="English"><label for = "gender">English</label></br>
<input type="checkbox" name="languages[]" id="languages" value="Spanish"><label for = "gender">Spanish</label></br>
<input type="checkbox" name="languages[]" id="languages" value="French"><label for = "gender">French</label></br>
<input type="checkbox" name="languages[]" id="languages" value="Germany"><label for = "gender">Germany</label></br>
<input type="checkbox" name="languages[]" id="languages" value="Chinese"><label for = "gender">Chinese</label></br>
<?php echo $languages_error, $languages_result ?></br>
<input type="submit" value="submit">
</fieldset>
</form>
</div>
</body>
</html>

将提交所选语言(复选框),并以PHP Array
提供。
要访问它们,您可以循环访问它们,并按原样回显:
$languages_result = $_POST['languages'];
foreach ($languages_result as $language) {
echo $language . '<br />';
}
// Result is:
// English
// Telegu
// Kanada
您还可以使用分隔符在String
中组合数组中的多个元素:
$languages_result = implode(', ', $_POST['languages']);
echo $languages_result;
// Result is:
// English, Telegu, Kanada
