Question

好的，我正在尝试制作一个注册页面：创建一个个人表，然后将用户添加到＆＃34; login＆＃34;表会发生什么事情是页面变成空白（因为我想要它）但它仍然永远不会使表格或广告成为用户

Sign4.php中的代码：

<?php

$host="localhost";
$username = "robx10ho_users";
$password = "stackoverflow";
$db_name="robx10ho_usersuse"; 
$tbl_name="login";

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

// Define $myusername and $mypassword 
$myusername=$_POST['myusername']; 
$mypassword=$_POST['mypassword']; 

// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql="SELECT * FROM $tbl_name WHERE Username='$myusername' and Password='$mypassword'";
$result=mysql_query($sql);

// Mysql_num_row is counting table row
$count=mysql_num_rows($result);

// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){
echo "Hello, ".$myusername.". This is your account list: "."<br>";
// Create connection
$conn = mysqli_connect($host, $username, $password, $db_name);
// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

$sql = "SELECT Username, Password, Membership FROM ".$myusername;
$result = mysqli_query($conn, $sql);

if (mysqli_num_rows($result) > 0) {
    // output data of each row
    while($row = mysqli_fetch_assoc($result)) {
        echo "Username: " . $row["Username"]. " | Password: " . $row["Password"]. " | Membership:" . $row["Membership"]. "<br>";
    }
} else {
    echo "0 results";
}

mysqli_close($conn);
}
else {
CREATE TABLE $myusername (
Username TEXT(300) NOT NULL,
Password TEXT(300) NOT NULL,
Membership TEXT(500) NOT NULL
)

INSERT INTO login ($myusername, $mypassword)
}
?>

这是我放在文件Signup.php中的代码：

<table width="300" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#00ffff" style="-webkit-border-radius: 10-moz-border-radius: 10;border-radius: 10px;font-family: Arial;color: #00ffff;font-size: 11px;padding: 10px 17px 10px 17px;">
<tr>
<form name="form1" method="post" action="http://rob.x10host.com/Sign4.php">
<td>
<table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF">
<tr>
<td colspan="3"><strong>Login to database. </strong></td>
</tr>
<tr>
<td width="78">Username: </td>
<td width="294"><input name="myusername" type="text" id="myusername"></td>
</tr>
<tr>
<td>Password: </td>
<td><input name="mypassword" type="password" id="mypassword"></td>
</tr>
<tr>
<td>&nbsp;</td>
<td>&nbsp;</td>
<td><input type="submit" name="Submit" value="Sign Up" style="  background: #d93434;background-image: -webkit-linear-gradient(top, #d93434, #ff0000);background-image: -moz-linear-gradient(top, #d93434, #ff0000);background-image: -ms-linear-gradient(top, #d93434, #ff0000);background-image: -o-linear-gradient(top, #d93434, #ff0000);background-image: linear-gradient(to bottom, #d93434, #ff0000);-webkit-border-radius: 10-moz-border-radius: 10;border-radius: 10px;font-family: Arial;color: #ffffff;font-size: 11px;padding: 6px 17px 6px 17px;text-decoration: none;"></td>
</tr>
</table>
</td>
</form>
</tr>
</table>

Answer 1

$sql = "CREATE TABLE $myusername (Username TEXT(300) NOT NULL, Password TEXT(300) NOT NULL, Membership TEXT(500) NOT NULL)";

if (mysqli_query($conn, $sql)) {
    echo "Table $myusername created successfully";
    $sql = "INSERT INTO login ($myusername, $mypassword)";

    if (mysqli_query($conn, $sql)) {
        echo "New user created successfully";
    } else {
        echo "Error: " . $sql . "<br>" . mysqli_error($conn);
    }
} else {
    echo "Error creating table: " . mysqli_error($conn);
}

pHp注册不起作用？
