嗨，我在第 20 行遇到错误 我已经尝试过 mysqli
Parse error: syntax error, unexpected 'mysql_query' (T_STRING) in C:\Users\User\l\htdocs\register.php on line 20
<html>
<body>
<?php
include("connect.php");
if(isset($_POST['register']))
$username= strip_tags(trim(mysql_real_ecape_string($_POST['username'])));
$password= strip_tags(trim(mysql_real_ecape_string($_POST['password'])));
if(!username || !$password){
echo "One of the fields are empty";
}else{
$find_multiple=" SELECT Username FROM register WHERE Username='$username' ";
$run_multiple = mysql_query($find_multiple) or die (mysql_error());
$num_multiple= mysql_num_rows($run_multiple);
if($num_multiple < 1){
$password= md5($password)
mysql_query("INSERT INTO register SET Username='$Username', Password='$Pasword' ") or die(mysql_error());
echo "You have succesfully registered!":
}else{
echo "That username has already beed used" ;
}
?>
<h1>Register</h1>
<form action='' method='post'>
username: <input type='text' name'username'/></br>
Password: <input type='password' name'password'/></br>
<input type='submit' value='Register'name='register'/>
</form>
注意:未定义索引:第 12 行 C:\Users\User\l\htdocs\register.php 中的用户名
注意:第 13 行 C:\Users\User\l\htdocs\register.php 中未定义索引:密码
<?php
$connect=mysql_connect("localhost","root","");
$db_selected = mysql_select_db("users", $connect);
if(isset($_POST['register'])){
$username= $_POST['username'];

}else{
$find_multiple=" SELECT username FROM resgistration WHERE username='$username' ";
$run_multiple = mysql_query($find_multiple) or die (mysql_error());
$num_multiple= mysql_num_rows($run_multiple);
if($num_multiple < 1){
$password= md5($password);
mysql_query( "INSERT INTO `resgistration` (`username`, `password`) VALUES ('".$username."', '".$password."')" ) or die(mysql_error());
echo "You have succesfully registered!";

<h1>Register</h1>

最佳答案
失踪；在这一行中:
$password= md5($password)
