hi

i need help an idea how can i separate members from admins
since i dont know how to create login form i used tutorial ( http://www.youtube.com/watch?v=4oSCuEtxRK8 )   (its session login form only that i made it work other tutorials wre too old or something)
how what i want to do is separate members and admins because admin need more rights to do
now i have idea but dont know will it work like that
what i want to do is create additional row in table named it flag and create 0 (inactive user) 1 (member) 2 (admin) will that work?
and how can i create different navigation bars for users and admins? do you recommend that i use different folders to create it or just script based on session and flag?

Hi guys.

What I want to create is really complicated. Well I have a login system that works with post on an external website.
I have my own website, but they do not give me access to the database for security reasons, therefore I have to use their login system to verify my users.
What their website does is that it has a post, with username and password. The POST website is lets say "https://www.example.com/login".
 If login is achieved (i.e. username and password are correct), it will redirect me to "https://www.example.com/login/success" else it will redirect me to "https://www.example.com/login/retry".

So I want a PHP script that will do that post, and then according to the redirected website address it will return me TRUE for success, FALSE for not successful login.

Any idea??

Thanks

How to add the ability to login with username or email for login?

 

<?php 
ob_start();
include('../header.php');
include_once("../db_connect.php");
session_start();
if(isset($_SESSION['user_id'])!="") {
	header("Location: ../dashboard");
}
if (isset($_POST['login'])) {
	$email = mysqli_real_escape_string($conn, $_POST['email']);
	$password = mysqli_real_escape_string($conn, $_POST['password']);
	$result = mysqli_query($conn, "SELECT * FROM users WHERE email = '" . $email. "' and pass = '" . md5($password). "'");
	if ($row = mysqli_fetch_array($result)) {
		$_SESSION['user_id'] = $row['uid'];
		$_SESSION['user_name'] = $row['user'];	
		$_SESSION['user_email'] = $row['email'];		
		header("Location: ../dashboard");
	} else {
		$error_message = "Incorrect Email or Password!!!";
	}
}

Hi everyone i wonder if you can help me he

I need a script for a login and check login- create cookie.

Here is my form:

<form method="post" action="check_login.php">
<p>
<input type="submit" name="Submit2" value="go" />
</fieldset>
</p>
</form>

that sends it to check_login (which BEFORE i deleted something by accident, used to take me to a username and password box)

But now all it does is send me straight to the memebrs area???


Can i change the check_login.php script to make it work correctly:

Code: [Select]

Hello, I am once again desperately asking for your help,

Hi all,

I am having some trouble with a part of code. Basically the code is set for a Factory to produce 750 items every 30 minutes. It does this fine IF AND ONLY IF someone clicks the Factory page. For example, it produces 750 bullets, then I leave the page alone for say 20 minutes, but when I click back, it doesn't have 10 minutes left before the next produce. Instead, It has 30 minutes. So it only produces when someone on the game clicks the page. I have tried the basic html refresh but that doesn't work.

Any idea's?

Thanks in advance

Hello,

I am creating a job setup form and have a need for the job id field to increment based on the last inserted job id into our Oracle database.
So far I have created a function that selects the maximum job id from the job table and adds 1 to the number.

However, I run into the problem of when a user is filling out the form and another user opens it and begins filling out the form they both will receive the same job id in the field. I'm assuming this could possibly be solved with sessions, but I'm not sure where to start.

Also, the form is not inserted into the table on submit (instead an excel sheet is created with the information and someone will enter the data into the database manually). Since the form data can be entered anytime from completion to next week/two weeks, how can I ensure that that job id is not used again.

Thanks

Hello

can anyone tell me why this function don't return anything ?


<?php include_once('./header.php'); ?>

<?php
    $var = Array();
    $data = $db->get("omnot", "fullname");
    
    foreach($data as $var){
        $var = $data;        
    }
    $input = strtolower( $_GET['input'] );   // the input is ok
    $len = strlen($input);
    
    
    $aResults = array();
    
    if ($len)
    {
        for ($i=0;$i<2;$i++)
        {
            if (strtolower(substr(utf8_decode($var),0,$len)) == $input)
                $aResults[] = array( "id"=>($i+1) ,"value"=>htmlspecialchars($var[$i]));
        }
    }


from the database i get the values: "roey" , "rrr" , "try"
input == r

why the function don't go to the line:  Code: [Select]
$aResults[] = array( "id"=>($i+1) ,"value"=>htmlspecialchars($var[$i]));
whats wrong with the IF ?

    $qGetId  =  "SELECT * FROM `polaroids` WHERE id='".$_GET['delete_polaroid']."'";
   $result = mysql_query($qGetId) or die (mysql_error()) ;
$pola=mysql_fetch_array($result);
 
$GetCat = "SELECT * FROM category WHERE cat_name='".$pola['catid']."'";

$GotCat = mysql_fetch_assoc($Result);

?>         
        <p class="bold">Are you sure you want to delete <?php echo $GotCat['cat_name'];?> and its image from the database?</p><br/>
