Data not Inserting into Database and no error - php

Question

I have a problem...
Im trying to take data inserted into my html5 form and insert it into a database. Now i have the form made along with a script that should be working; instead there is no data being inserted into the database and there is no error showing. Please help.
form.php
<form name="loginForm" method="post" action="process.php">
<input id="username" type="text" placeholder="Username" name="username">
<input id="password" type="password" placeholder="Password" name="password">
<input type="submit" id="Login" class="form-control" value="Log In">
</form>
process.php
<?
$username=$_POST['username'];
$password=$_POST['password'];
mysql_connect("localhost", "root", "toor") or die(mysql_error());
mysql_select_db("formd") or die(mysql_error()); mysql_query("INSERT INTO `data` VALUES ('$username', '$password')");
Print "Your information has been successfully added to the database.";
?>
Now i know this isnt a secure way to store passwords or usernames but this isnt for any website really i just wanna know how to take information from my form and store it into a database.

Answer 1

You've added minimal error handling to all mysql functions call but the one involved in the actual query....
The script is also prone to sql injections.
The mysql_* extension is mared as deprecated, better pick another mysql extension.
<?php
$mysql = mysql_connect("localhost", "root", "toor")
or die(mysql_error());
mysql_select_db("formd", $mysql)
or die(mysql_error($mysql));
$username=mysql_real_escape_string($_POST['username'], $mysql);
$password=mysql_real_escape_string($_POST['password'], $mysql);
mysql_query("INSERT INTO `data` VALUES ('$username', '$password')", $mysql)
or die(mysql_error($mysql));
echo "Your information has been successfully added to the database.";
using or die(mysql_error()) can lead to Information Leakage issues

Im still learning the very basics myself, i have not tested this and just snipped it out of a very long sql script i have so it may work and may not, hopefully it does help you out.. if not take a look at the link below the code. Hope it works for you or may need a little tweak. Thanks
<?php
if (isset($_POST['submit'])) {
$submit = $_POST['submit'];
$username = $_POST['username'];
$password = $_POST['password'];
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'toor';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if (!$conn) {
die('Could not connect: '.mysql_error());
}
$sql = "INSERT INTO data (username','password')
VALUES('$username','$password')";
mysql_select_db('formd');
$retval = mysql_query($sql, $conn);
if (!$retval) {
die('Could not enter your data: '.mysql_error());
}
echo "Entered your dara successfully\n";
mysql_close($conn);
} else {
echo "Something has gone wrong.";
}
?>
