在php上回显我的表单值 [英] echo my form values on php
问题描述
我正在使用下面的代码来打印插入框中的值。然而，当我把值，然后点击提交没有打印出来。
< html>
< body>
< form action =<？php $ _SERVER ['PHP_SELF']？>方法= POST >
名称：< input type =textname =name>< br>
电子邮件：< input type =textname =email>< br>
< input type =submit>
< / form>
<？php
if（isset（$ _ POST [submit]））{
$ name = filter_input（INPUT_POST，'name'）;
$ email = $ _POST ['email'];
echo $ name;
echo $ email;
}
？>
< / body>
< / html>
关于下面我试过这两种情况，因为在简单的$ _POST ['email']警告：
$ name = filter_input（INPUT_POST，'name'）;
$ email = $ _POST ['email'];
警告：
直接访问超全局$ _POST数组
我使用Netbeans IDE 8.2。
<
if（isset（$ _POST [submit]））{
改为：
if（count（$ _ POST）> 0）{
您没有任何匹配 name =submit的元素。另外，使用 isset（$ _ POST [submit]）是一种不好的做法，因为我们很多人都不会将其命名。
如果您想检查设置的具体内容，您需要执行以下操作：
<$ c $ （$ _ POST ['email']））{
如果你还想让你的代码在上面的设置中工作，请添加一个 Am using the code below in order to print the values that am inserting on the boxes. However After I put the values and click submit nothing is printing out. About below I tried both cases because on the simple one $_POST['email'] I was getting a warning: Warning: Do not Access Superglobal $_POST Array Directly I am using Netbeans IDE 8.2. This is never set: Instead change it to: You don't have any elements matching If you want to check for specific things set, like in your case, you need to do: If still you wanna make your code work with the above set-up, kindly add a

$ p $ < code>< code>< code>< input type =提交name =submitvalue =提交/>
<html>
<body>
<form action="<?php $_SERVER['PHP_SELF']?>" method="post">
Name: <input type="text" name="name"><br>
E-mail: <input type="text" name="email"><br>
<input type="submit">
</form>
<?php
if(isset($_POST["submit"])) {
$name = filter_input(INPUT_POST, 'name');
$email = $_POST['email'];
echo $name;
echo $email;
}
?>
</body>
</html>
$name = filter_input(INPUT_POST, 'name');
$email = $_POST['email'];
if (isset($_POST["submit"])) {
if (count($_POST) > 0) {
name="submit". Also, it is a bad practise to use isset($_POST["submit"]) as many of us, won't name it.if (count($_POST) > 0 && isset($_POST["name"]) && isset($_POST['email'])) {
name and value here:<input type="submit" name="submit" value="Submit" />
