You need to post your code in the forum using the code tags.



// form to insert the data

<input type="text" name="first" placeholder="Firstname">
<input type="text" name="last" placeholder="Lastname">
<input type="text" name="email" placeholder="E-mail">
<input type="text" name="uid" placeholder="Username">
<input type="password" name="pwd" placeholder="Password">
<button type="submit" name="submit">Sign up</button>
//---------------------------------------------------------------------------------------------------------------------------- // read from database <?php include_once'includes/'; ?> Database <?php $data = "adm34"; // Created a template $sql = "SELECT * FROM users WHERE user_uid = ?;"; // Created a prepared statement $stmt = mysqli_stmt_init($conn); // Prepare the prepared statement if(!mysqli_stmt_prepare($stmt, $sql)){ echo "SQL statement faild"; }else { // Bind the parameter to the placeholder mysqli_stmt_bind_param($stmt, "s", $data);// s is for sting // Run paramerter inside database mysqli_stmt_execute($stmt); $result = mysqli_stmt_get_result($stmt); while ($row = mysqli_fetch_assoc($result)) { echo $row['user_uid']."
"; echo $row['user_email']."
"; echo $row['user_first']."
"; } } ?> //--------------------------------------------------------------------------------------------------- // // connect the database <?php

$dbServername = “localhost”;
$dbUsername = “root”;
$dbPasswort = “”;
$dbName = “loginsystem”;

$conn = mysqli_connect($dbServername,$dbUsername,$dbPasswort,$dbName);

// signup in the database

<?php include_once''; $first = mysqli_real_escape_string($conn, $_POST['first']); $last = mysqli_real_escape_string($conn, $_POST['last']); $email = mysqli_real_escape_string($conn, $_POST['email']); $uid = mysqli_real_escape_string($conn, $_POST['uid']); $pwd = mysqli_real_escape_string($conn, $_POST['pwd']); $sql = "INSERT INTO users (user_first,user_last,user_email,user_uid,user_pwd) VALUES('?','?','?','?','?');"; $stmt = mysqli_stmt_init($conn); if(!mysqli_stmt_prepare($stmt, $sql)){ echo "SQL faild"; }else { mysqli_stmt_bind_param($stmt, 'sssss', $first, $last, $email, $uid, $pwd); mysqli_stmt_execute($stmt); } header("Location: ../insert.php?signup=sucscess"); [/php] I hope it is ok now


You need to remove the quotes from around the question marks.

You really should be using PDO. Here is a tutorial to get you going
