新人求助啊！关于表单的
我做了个简单的留言板，只写了一小部分，可是规则写了，比如我不输标题，在前台还是无法显示错误，求帮助
------------------------------------------这是留言板模板：
nbsp;html>
留言板
------------------------------------------这是验证部分：
//留言板验证规则
if($_SERVER["REQUEST_METHOD"] == "POST"){
if(empty($_POST["name"])){
$nameError = "用户名不能为空";
}else{
$name = test_input($_POST["name"]);
}
if(empty($_POST["title"])){
$titleError = "标题不能为空";
}else{
$title = test_input($_POST["title"]);
}
if(empty($_POST["content"])){
$contentError = "评论内容不能为空";
}else{
$content = test_input($_POST["content"]);
}
}
//去除空格及反斜线方法
function test_input($data){
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
------解决思路----------------------
nbsp;html>
$nameError = $titleError= $contentError = "";?>
//留言板验证规则
if($_SERVER["REQUEST_METHOD"] == "POST"){
if(empty($_POST["name"])){
$nameError = "用户名不能为空";
}else{
$name = test_input($_POST["name"]);
}
if(empty($_POST["title"])){
$titleError = "标题不能为空";
}else{
$title = test_input($_POST["title"]);
}
if(empty($_POST["content"])){
$contentError = "评论内容不能为空";
}else{
$content = test_input($_POST["content"]);
}
}
//去除空格及反斜线方法
function test_input($data){
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
?>
