Login System Lets do it :)

First, let's do register.php:

 

<?

include("conn.php"); // create a file with all the database connections

 

if($do_register){ // if the submit button were clicked

if((!$name) || (!$email) || (!$age) || (!$login) || (!$password) || (!$password2)){

print "You can't let any fields in blank.\n"; // if the user did not put some field

exit;

}

$name = stripslashes($name);

$email = stripslashes($email);

$age = stripslashes($age);

$login = stripslashes($login);

$password = stripslashes($password);

$password2 = stripslashes($password2);

 

// this is for security reasons

 

if($password != $password2){ // if passwords didn't match

print "The password and the confirmation are not the same!\n";

exit;

}

$password = md5($password);

mysql_query("INSERT INTO table (name,email,age,login,password) VALUES ('$name','$email',$age,'$login','$password')") or die (mysql_error());

print "Done!\n"; // if its okay, show this message

exit;

} // close the first "if"

?>

 

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

Name: <input type="text" name="name"><br>

Email: <input type="text" name="email"><br>

Age: <input type="text" name="age"><br>

Login: <input type="text" name="login"><br>

Password: <input type="password" name="password"><br>

Password Again: <input type="password" name="password2"><br>

<input type="submit" name="do_register" value="Sumbit">

</form>

 

And now, login.php:

 

<?

include("conn.php");

 

if($do_login){

$login = stripslashes($login); // VERY IMPORTANT FOR SECURITY OF YOUR DATABASE DON'T ERASE IT

$passwd = stripslashes($passwd); // VERY IMPORTANT FOR SECURITY OF YOUR DATABASE DON'T ERASE IT

 

$check = mysql_query("SELECT * FROM table WHERE login='$login' LIMIT 1;");

$user = mysql_fetch_array($check);

 

if($user[password] == md5($passwd)){ // if the writed password and the db password are the same...

 

setcookie("login","$login",time()+360000);

setcookie("pass","$passwd",time()+360000);

// ...set the cookies...

header("Location: userspage.php"); // ...and redirect to restrict page

}else{

print "Login or password incorrects!\n";

exit;

}

}

?>

 

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

Login: <input type="text" name="login"><br>

Passwd: <input type="password" name="passwd">

<input type="submit" name="do_login" value="Log-in!">

</form>

 

And finally, userspage.php:

 

<?

if(isset($HTTP_COOKIE_VARS["login"])){

?>

 

Page contents here

 

<?

}else{

?>

This page is restrict for registered users only!

<?

}

?>

 

Here we are, its a very simple login sistem and you can put more things if u want. Maybe latelly I make an administration page and put here to. If u found any problems with this code, tell me and I'll fix! \_

 

-------------------- Edit -------------------------

Field password2 was in type="text". Changed by type="password".

Field "login" was name="name". This litle mistake caused very much problems!

Sumbit button was wrong. I write type="sumbit". Change by type="submit".

Really nice FaLgor.I was asking myself for a long time how could i set a login system with php and you give the clue. Somethings about your script:- What is exactly conn.php and why is it necessary in register.php?

WOW! that is just what I was looking for...

Thank you,

I know you must be fed up of me asking you things all the time,

But there are a few more pages tat would be a good idea..

profile.php to view each members profile it would be something like profile.php?id=2

 

Also edit.php do thst they can chnage thier info... (excluding their username, they must request for this to happen)

hehehe, I start this topic because I saw you were needing it :rolleyes:Latelly I'll try to complete this topic by posting an administration page, where you can see the members, edit, delete and send them e-mails. Oh, yes, and a page where the members can see their profiles and edit it, just wait a bit

Ok, I will, thanks,You are the best thing since PHP itself!

mizako conn.php is the file with all the connection setings. Ex.<?$host = 'localhost';$user = 'root';$pass = 'pass';$dbname = 'members';mysql_connect($host,$user,$pass);mysql_select_db($dbname);?>So, when you in include this file on your pages, it will do the connection with the database. If would you have to put this code on all your pages, you would lose loads of time, so using includes() will does your work easilly.

Now, let's complete our login sistem. First, lets make an page which will verify if the logged member is an admin. Oh yes, and you will have to put one more columns on the member's table, "level", and put "Member" as the default value.

 

verify.php:

<?

include("conn.php"); // include page with the database connection

$cookie = $HTTP_COOKIE_VARS; // to reduce the var's name )

 

if($cookie[login] && $cookie[pass]){

 

$login = $cookie[login];

$pass = $cookie[pass];

 

$usrquery = mysql_query("SELECT * FROM members WHERE nick='$login' AND password='$pass';") or die (mysql_error()); // search for the user

$user = mysql_fetch_array($usrquery);

 

if($user[level] != 'Admin')

header("Location: notfound.htm"); // if the user is not an admin, redirect to an error page

}

?>

 

admin.php:

<?

include("verify.php"); // it will verify if the user is an admin

?>

<!-- Here, the table with all the members -->

<table width="100%" border="0" cellspacing="0" cellpadding="0">

<tr>

<td>

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

<table width="100%" border="0" cellspacing="3" cellpadding="0">

<tr bgcolor="#333333">

<th width="6%" class="header"><font size="1">Editar</font></th>

<th width="1%" class="header"><font size="1">ID</font></th>

<th width="24%" class="header"><font size="1">Name</font></th>

<th width="13%" class="header"><font size="1">Age</font></th>

<th width="40%" class="header"><font size="1">E-Mail</font></th>

<th width="11%" class="header"><font size="1">Details...</font></th>

</tr>

<?

$query = mysql_query("SELECT * FROM members ORDER BY id;");

if(!mysql_fetch_array($query)) // If there is no members

print "<tr><td align=\"center\" colspan=\"7\"><font color=\"#FFFFFF\" size=\"2\"><b>Sorry, there is no members registered.</b></font></td></tr>\n";

// Show you a message

 

while($profiles = mysql_fetch_array($query))

{

?>

<tr bgcolor="#666666">

<td> <div align="center"><input type="checkbox" name="id[]" value="<?=$profiles[id]?>"></div></td>

<td> <div align="center"><?=$profiles[id]?></div></td>

<td> <div align="center"><?=$profiles[name]?></div></td>

<td> <div align="center"><?=$profiles[age]?></div></td>

<td> <div align="center"><?=$profiles?></div></td>

<td> <div align="center"><a href="profiles.php?op=edit&id=<?=$profiles[id]?>" target="_blank">More info...</a></div></td>

</tr>

<?

}

?>

</table>

</td>

</tr>

</table>

</form>

 

Done, now, profiles.php (used to see and edit member information):

<?

include("verify.php"); // always put this page, or everybody would have access to this page

 

function Update (&$member, $table, $data)

{

global $id;

$items = explode(" ",$data);

$update = "";

$i = 0;

while ($tmp = $items[$i++])

{

$data = $member[$tmp];

if (is_numeric($data))

$update .= "$tmp=$data";

else

{

sqlQuotes($data);

$update .= "$tmp='$data'";

}

if ($items[$i]) $update .= ",";

}

mysql_query("UPDATE $table SET $update WHERE id=$member[id];");

 

}

// this function is really nice!!

 

switch($op){

case 'edit': // if you're trying to edit/see info

$profile = mysql_fetch_array(mysql_query("SELECT * FROM members WHERE id=$id;")); // save the user informations on an variable

?>

<!-- now, lets show an table -->

<form action="profiles.php?op=doedit&memberid=<?=$profile[id]?>" method="post">

<table width="100%" border="0" cellspacing="3" cellpadding="0">

<tr>

<td width="25%"><font color="#FFFFFF">ID</font></td>

<td width="75%"><input name="id" type="text" id="id" value="<?=$profile[id]?>" size="2"></td>

</tr>

<tr>

<td><font color="#FFFFFF">Name</font></td>

<td><input name="name" type="text" id="nome" value="<?=$profile[name]?>" maxlength="32"></td>

</tr>

<tr>

<td><font color="#FFFFFF">Age</font></td>

<td><input name="age" type="text" value="<?=$profile[age]?>" maxlength="32"></td>

</tr>

<tr>

<td><input name="country" type="text" id="estado" value="<?=$profile[country]?>" size="2" maxlength="2"></td>

</tr>

<tr>

<td><font color="#FFFFFF">City</font></td>

<td><input name="city" type="text" id="cidade" value="<?=$profile[city]?>"></td>

</tr>

<tr>

<td><font color="#FFFFFF">ICQ</font></td>

<td><input name="icq" type="text" id="icq" value="<?=$profile[icq]?>"></td>

</tr>

<tr>

<td height="22"><font color="#FFFFFF">MSN</font></td>

<td><input name="msn" type="text" id="msn" value="<?=$profile[msn]?>"></td>

</tr>

<tr>

<td><font color="#FFFFFF">HP</font></td>

<td><input name="hp" type="text" id="hp" value="<?=$profile[hp]?>" size="40"></td>

</tr>

<tr>

</tr>

<tr>

<td colspan="2"> </td>

</tr>

<tr>

<td colspan="2"><div align="center">

<input type="submit" value="Save">

 

<input type="reset" value="Reset">

</div></td>

</tr>

</table>

</form>

<?

break;

case 'doedit':

if(!$memberid)

return;

 

$profile[name] = $name;

$profile[age] = $age;

$profile[country] = $country;

$profile[city] = $city;

$profile[icq] = $icq;

$profile[msn] = $msn;

$profile[hp] = $hp;

$profile = $email;

 

Update($profile,"members","name age country city icq msn hp email");

mysql_query("UPDATE members SET id=$id WHERE id=$memberid;"); // update user's id

 

EndNow("Details saved!<br><br><a href=\"admin.php\">Back</a>");

 

break;

}

?>

 

Done ! I did not tested this script, so, if there is something wrong tell me. But I think it will give you some idea that how to do an administration page! Next post I'll show you how to do an page where the members can change their details (but I think, after saw this post, you will not have problems to do it). I hope I have helped you all! =D

You missed out the </form> near the end of admin.php


And I added aim (AOL instant messenger) to profiles.php and also added the other fields to the database...


EDIT: error in login.php

http://forums.xisto.com/no_longer_exists/
i put things in but it says i shouldnt leave any blank... please help thanks

if you want an page where the members can view and edit their account details, just copy profiles.php of the administration page, erase the line including verify.php and put this code in the place where the include was:include("conn.php"); // include page with the database connection$cookie = $HTTP_COOKIE_VARS; // to reduce the var's nameif($cookie[login] && $cookie[pass]){$login = $cookie[login];$pass = $cookie[pass];if(!isset($cookie["login"])) header("Location: denied.htm"); // if the user is not logged in, redirect to an error page}that's all, if you think I've forgot some important thing here, tell me and I'll try to make it! =]\_
