HTML文档中没有加载HTML
[英]HTML not being loaded in PHP Document
问题描述
I am writing a basic PHP login/Registration script and for some reason as soon as I add a PHP command the HTML isn't loaded. 
我正在编写一个基本的PHP登录/注册脚本，出于某种原因，只要我添加PHP命令，就不会加载HTML。 I had a look at the source but there is nothing loaded at all. 我查看了源代码，但根本没有任何内容。 I am hoping I have missed something very basic, but I am also having a couple of teething issues with the version of PHP installed on the web server. 我希望我错过了一些非常基本的东西，但我对Web服务器上安装的PHP版本也有一些问题。
<?php
require_once('connect.php');
if(isset($_POST) & !empty($_POST)){
$username = mysql_real_escape_string($_POST['username']);
$email = mysql_real_escape_string($_POST['email']);
$password =md5($_POST['password']);
$sql = "INSERT INTO 'login' (username, email, password) VALUES ('$username, $email, $password)";
$result = mysql_query($connection, $sql);
if($result){
echo "User Rego Secusseflllgk";
}else{
echo "User rego faile";
}
}
?>

I tried to print the POST request but this didnt shed any light on the issue 我试图打印POST请求，但这并没有解决这个问题
print_r($_POST);

You are using deprecated functions and your if-statement is incorrect. 您正在使用已弃用的函数，并且您的if语句不正确。
Use if(isset($_POST) && !empty($_POST)){ 使用if(isset($_POST) && !empty($_POST)){
The mysql_query should be mysqli_query , the function you use: mysql_query应该是mysqli_query ，你使用的函数：
http://php.net/manual/en/function.mysql-query.php http://php.net/manual/en/function.mysql-query.php
mixed mysql_query ( string $query [, resource $link_identifier = NULL ] )
VS the new one: VS新的：
http://php.net/manual/en/mysqli.query.php http://php.net/manual/en/mysqli.query.php
mixed mysqli_query ( mysqli $link , string $query [, int $resultmode = MYSQLI_STORE_RESULT ] )
You are placing the connection first, and than the Query, which doesn't work for mysql_query. 您首先放置连接，而不是查询，这对mysql_query不起作用。 In mysqli_query that mark-up does work. 在mysqli_query中，标记确实有效。

用这个
if(isset($_POST['email']) && !empty($_POST['email'])){
