Many interactive websites these days need a user to log in into the web site’s system to provide a customized experience for the user. Once the user has logged in, the web site will be in a position to provide a presentation that is customized to the user’s preferences.
A basic login system usually contains three parts that can be created using PHP and MySQL :
Component one: Allows registration of preferred login Id and password.
This is created in simple HTML type that contains three fields and 2 buttons:
1. A most well-liked login id field
2. A most well-liked password field
3. A legitimate email address field
4. A Submit button
5. A Reset button
Shall we say the shape is coded into a file named register.html. The following HTML code extract could be a typical example. When the user has filled in all the fields and clicks on the submit button, the register.php page is called for.
[type name="register" method="post" action="register.php"]
[input name="login id" sort="text" worth="loginid" size="twenty"/][br]
[input name="password" sort="text" value="password" size="twenty"/][br]
[input name="email" sort="text" value="email" size="50"/][br]
[input sort="submit" name="submit" worth="submit"/]
[input type="reset" name="reset" price="reset"/]
[/kind]
The following code extract can also be used as part of register.php to process the registration. The code connects to the MySQL database and inserts a line of information into the table used to store the registration information.
@mysql_connect(”localhost”, “mysql_login”, “mysql_pwd”) or die(”Cannot hook up with DB!”);
@mysql_select_db(”tbl_login”) or die(”Cannot choose DB!”);
$sql=”INSERT INTO login_tbl (loginid, password and email) VALUES (”.$loginid.”,”.$password.”,”.$email.”)”;
$r = mysql_query($sql);
if(!$r) {
$err=mysql_error();
print $err;
exit();
}
The code extract assumes {that the} MySQL table that is used to store the registration data is called tbl_login and contains 3 fields - the loginid, password and email fields. The values of the $loginid, $password and $email variables are passed in from the shape in register.html using the post method.
Element two: Verification and authentication of the user.
In this the HTML type typically contains two fields and a couple of buttons:
1. A login id field
2. A password field
3. A Submit button
4. A Reset button
Assume that such a kind is coded into a file named authenticate.html. The subsequent HTML code extract may be a typical example. When the user has filled in all the fields, the authenticate.php page is called when the user clicks on the Submit button.
[kind name="authenticate" technique="post" action="authenticate.php"]
[input name="login id" kind="text" worth="loginid" size="20"/][br]
[input name="password" kind="text" worth="password" size="20"/][br]
[input sort="submit" name="submit" price="submit"/]
[input sort="reset" name="reset" price="reset"/]
[/type]
The subsequent code extract can be used as half of authenticate.php to process the login request. It connects to the MySQL database and queries the table used to store the registration information.
@mysql_connect(”localhost”, “mysql_login”, “mysql_pwd”) or die(”Cannot connect with DB!”);
@mysql_select_db(”tbl_login”) or die(”Cannot choose DB!”);
$sql=”SELECT loginid FROM login_tbl WHERE loginid=’”.$loginid.”‘ and password=’”.$password.”‘”;
$r = mysql_query($sql);
if(!$r) {
$err=mysql_error();
print $err;
exit();
}
if(mysql_affected_rows()==zero){
print “no such login within the system. please attempt again.”;
exit();
}
else{
print “successfully logged into system.”;
//proceed to perform website’s functionality - e.g. gift information to the user
}
As in component one, the code excerpt assumes {that the} MySQL table that’s used to store the registration knowledge is called tbl_login and contains three fields - the loginid, password and email fields. The values of the $loginid and $password variables are passed in from the form in authenticate.html using the post method.
Part three: When the user forgets his logion password this 3rd component sends his password to the users registered email address.
The HTML kind sometimes contains 1 field and a pair of buttons:
• A login id field
• A Submit button
• A Reset button
Assume that such a kind is coded into a file named forgot.html. The following HTML code excerpt may be a typical example. When the user has filled in all the fields, the forgot.php page is termed when the user clicks on the Submit button.
[type name="forgot" methodology="post" action="forgot.php"]
[input name="login id" sort="text" price="loginid" size="20"/][br]
[input kind="submit" name="submit" value="submit"/]
[input sort="reset" name="reset" value="reset"/]
[/kind]
The subsequent code excerpt can be used as part of forgot.php to method the login request. It connects to the MySQL database and queries the table used to store the registration information.
@mysql_connect(”localhost”, “mysql_login”, “mysql_pwd”) or die(”Cannot hook up with DB!”);
@mysql_select_db(”tbl_login”) or die(”Cannot select DB!”);
$sql=”SELECT password, email FROM login_tbl WHERE loginid=’”.$loginid.”‘”;
$r = mysql_query($sql);
if(!$r) {
$err=mysql_error();
print $err;
exit();
}
if(mysql_affected_rows()==zero){
print “no such login within the system. please try again.”;
exit();
}
else {
$row=mysql_fetch_array($r);
$password=$row["password"];
$email=$row["email"];
$subject=”your password”;
$header=”from:you@yourdomain.com”;
$content=”your password is “.$password;
mail($email, $subject, $row, $header);
print “An email containing the password has been sent to you”;
}
As in element one, the code excerpt assumes {that the} MySQL table that’s used to store the registration data is known as tbl_login and contains 3 fields - the loginid, password and email fields. The value of the $loginid variable is passed from the shape in forgot.html using the post method.
This can be how a basic login system can be created. The software developer will embody extra tools like password encryption, access to the user profile in case they want to edit their profile etc.
