HTML Log In form connection to database - php

Question

I am facing problems connecting my HTML form to database. I am very new at this. Please do help me.
This is the HTML Login form code
logout.html
<form name="form" onsubmit="submit1()" action="connectivity-sign-up.php" method="POST" >
<div id="errorBox"></div>
<input type="text" name="Name" value="" placeholder="First Name" class="input_name" >
<input type="text" name="LastName" value="" placeholder="Last Name" class="input_name" >
</div>
<div id="email_form">
<input type="text" name="Email" value="" placeholder="Your Email" class="input_email">
</div>
<div id="Re_email_form">
<input type="text" name="enterEmail" value="" placeholder="Re-enter Email" class="input_Re_email">
</div>
<div id="password_form">
<input type="password" name="Password" value="" placeholder="New Password" class="input_password">
</div>
<!--birthday details start-->
<div>
<h3 class="birthday_title">Birthday</h3>
</div>
<div>
<select name="birthday_month" >
<option value="" selected >Month</option>
<option value="1">Jan</option>
<option value="2">Feb</option>
<option value="3">Mar</option>
<option value="4">Apr</option>
<option value="5">May</option>
</select>
<select name="birthday_day" >
<option value="" selected>Day</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
<select name="birthday_year">
<option value="" selected>Year</option>
<option value="2013">2013</option>
<option value="2012">2012</option>
<option value="2011">2011</option>
<option value="2010">2010</option>
<option value="2009">2009</option>
</select>
</div>
<!--birthday details ends-->
<div id="radio_button">
<input type="radio" name="radiobutton" value="Female">
<label >Female</label>
<input type="radio" name="radiobutton" value="Male">
<label >Male</label>
</div>
<div>
<p id="sign_user" onClick="Submit()" value= "Submit" >Sign Up </p>
<input type="submit" value="Submit">
</div>
</form>
The Submit1() function is the validate function. When I click Submit it should first validate and then send the data to the form. Now the validate function works properly but how do I call it such that it will send the data once validated.And here is the PHP connectivity part
File name : connectivity-sign-up.php
<?php define('DB_HOST', 'localhost');
define('DB_NAME', 'customerdb');
define('DB_USER','root');
define('DB_PASSWORD','');
$con=mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or die("Failed to connect to MySQL: " . mysql_error());
$db=mysql_select_db(DB_NAME,$con) or die("Failed to connect to MySQL: " . mysql_error());
function Signin()
{
$fname = $_POST['Name'];
$lname = $_POST['LastName'];
$email = $_POST['Email'];
$password = $_POST['Password'];
$query = "INSERT INTO custtable (fname,lname,email,password) VALUES ('$fname','$lname','$email','$password')";
$data = mysql_query ($query)or die(mysql_error());
if($data)
{
echo "YOUR REGISTRATION IS COMPLETED...";
}
}
?>

Answer 1

When user click submit button call Signin() function.
if (isset($_POST['submit'])) {
Signin();
}
-
<?php define('DB_HOST', 'localhost');
define('DB_NAME', 'customerdb');
define('DB_USER', 'root');
define('DB_PASSWORD', '');
$con = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD) or die("Failed to connect to MySQL: " . mysql_error());
$db = mysql_select_db(DB_NAME, $con) or die("Failed to connect to MySQL: " . mysql_error());
if (isset($_POST['submit'])) {
Signin();
}
function Signin()
{
$fname = $_POST['Name'];
$lname = $_POST['LastName'];
$email = $_POST['Email'];
$password = $_POST['Password'];
$query = "INSERT INTO custtable (fname,lname,email,password) VALUES ('$fname','$lname','$email','$password')";
$data = mysql_query($query) or die(mysql_error());
if ($data) {
echo "YOUR REGISTRATION IS COMPLETED...";
}
}
?>
Update html : <input type="submit" name="submit" value="Submit">
<!--birthday details ends-->
<div id="radio_button">
<input type="radio" name="radiobutton" value="Female">
<label>Female</label>
<input type="radio" name="radiobutton" value="Male">
<label>Male</label>
</div>
<div>
<p id="sign_user" onClick="Submit()" value="Submit">Sign Up </p>
<input type="submit" name="submit" value="Submit">
</div>
</form>

Answer 2

When click Sign Up, the information will be send to connectivity-sign-up.php, and execute the code in connectivity-sign-up.php. And Signin() is not invoked, there is just a declare.
<?php define('DB_HOST', 'localhost');
define('DB_NAME', 'customerdb');
define('DB_USER','root');
define('DB_PASSWORD','');
$con=mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or die("Failed to connect to MySQL: " . mysql_error());
$db=mysql_select_db(DB_NAME,$con) or die("Failed to connect to MySQL: " . mysql_error());
function Signin()
{
$fname = $_POST['Name'];
$lname = $_POST['LastName'];
$email = $_POST['Email'];
$password = $_POST['Password'];
$query = "INSERT INTO custtable (fname,lname,email,password) VALUES ('$fname','$lname','$email','$password')";
$data = mysql_query ($query)or die(mysql_error());
if($data)
{
echo "YOUR REGISTRATION IS COMPLETED...";
}
}
//invoke Signin
Signin();
?>

Answer 3

If you remove the method declaration for Signin() and just have the entire page as a script, then the logic you have in the function will execute. This would result in the following file:
<?php define('DB_HOST', 'localhost');
define('DB_NAME', 'customerdb');
define('DB_USER','root');
define('DB_PASSWORD','');
$con=mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or die("Failed to connect to MySQL: " . mysql_error());
$db=mysql_select_db(DB_NAME,$con) or die("Failed to connect to MySQL: " . mysql_error());
$fname = $_POST['Name'];
$lname = $_POST['LastName'];
$email = $_POST['Email'];
$password = $_POST['Password'];
$query = "INSERT INTO custtable (fname,lname,email,password) VALUES ('$fname','$lname','$email','$password')";
$data = mysql_query ($query)or die(mysql_error());
if($data)
{
echo "YOUR REGISTRATION IS COMPLETED...";
}
?>
Another alternative is to actually call the function somewhere in the page like so:
Signin()

Answer 4

The better option would be executing the Signin() function somewhere in the page.And you would need to add a connetion between the connectivity-sign-up.php and logout.html file
