PHP Error - NOTICE: Undefined index

Recommended Posts

Hi everyone.


So I am have an issue to were I am trying to send information to my database and I get this error:


NOTICE: Undefined index


This is the code I am using:



<!DOCTYPE html>
        <meta charset="UTF-8">
        <title>Test Page</title>
        <link rel="stylesheet" type="text/css" href="style.css">


        <form action="signup.php" methos="POST">
            <input type="text" name="first" placeholder="First Name"><br>
            <input type="text" name="last" placeholder="Last Name"><br>
            <input type="text" name="uid" placeholder="Username"><br>
            <input type="password" name="pwd" placeholder="Password"><br>
            <button type="submit">SIGN UP</button>




include 'dbh.php';

$first = $_POST['first'];
$last = $_POST['last'];
$uid = $_POST['uid'];
$pwd = $_POST['pwd'];

$sql = "INSERT INTO username (first, last, uid, pwd)
VALUES ('$first', '$last', '$uid', '$pwd')";
$result = mysqli_query($conn, $sql);




$conn = mysqli_connect("localhost", "root", "", "logintest");

if (!$conn) {
    die("Connection failed: ".mysqli_connect_error());


So this is the code I am using. I know it is connecting to the database because the PRIMARY KEY is entering without an issue but the information is now being filled in. I.E. First name, Last name, User, and Password.


If anyone can help me that would be great.

'is now' ??? 'is not' no index means you are referring to name not within $_POST array, which is probably because of

<form action="signup.php" methos="POST">


instead of


<form action="signup.php" method="post">


if primary key is auto increment it will add value if the other fields accept null.

Okay one more thing and I should be good.


I got all that fixed and worked out, but now I am trying to create a login and I am getting this error:



Warning: mysqli_fetch_assoc() expects parameter 1 to be resource, boolean given in



Here is the code that I am working with:




include 'dbh.php';

$uid = $_POST['uid'];
$pwd = $_POST['pwd'];

$sql = "SELECT * FROM username WHERE uid='$uid' AND pwd'$pwd'";
$result = mysqli_query($conn, $sql);

if (!$row = mysqli_fetch_assoc($result)) {
    echo "Username or password is incorrect";
}   else {
    echo "You are logging in";

//header("Location: index.php");
