Re: login page is not working

More importantly, $_SESSION["status"] will not be set even if you have been through the login page, so it won't even get to the $_SESSION["status"] != true condition.

why?

so let me see if I understood..

I changed to this but still the same result:

PHP

<?php
	session_start();
	
	if (isset($_SESSION["status"]) && $_SESSION["status"] != true)
	{
		header('Location:login.php');
	}
?>

Is there Dictionary Object in PHP

You are setting the status to true if the user logs in successfully.

If the user does not log in, then $_SESSION['status'] is not being set to anything.

You should redirect to the login page whenever $_SESSION['status'] is not set - and unless you have a page somewhere else that sets it to anything other than true, you don't even need to check what its value is.

Hi guys;

I wish to store KeyValuePair collection as I do in C# or VB.NET. Is there a way to achieve this in PHP and how?

Thanks for your cordial supports.

You can do that using an array:

<?php
$dict = array('a' => 1, 'b' => 2, 'z' => 0);
$dict['c'] = 5;
$dict['a more complex value'] = array('X' => 'OK');

foreach($dict as $key => $value)
  echo "$key : $value<br />\n";

If a function doesn't do what you expect it to, you should go back and read the manual. The second argument to the date function should be an integer timestamp, but you are giving it a string.

You can get an integer timestamp from your string using the strtotime function[^].

Have you tried

<?php echo date_format($date, 'd-m-Y H:i:s'); ?>

2nd arguement requires a unix timestamp. Take a look at date() and mktime() functions in the manual.

If your dat coming from the db is a datetime stamp you may want to use strtotime() to convert it into the unix timestamp needed for the 2nd date arg.

does the include file Piwik.php have any output?

try hiding it and see if you issue persist.

This is not a PHP problem, it's a CSS style issue. Try setting the height of the and tags to 100% and 'absolutely' position the outer table (or better still, replace it with a div)

That should solve the problem...

You can't do a cross server include like that. PHP include directive only works with files on the same webserver. The way I see it you have two options to solve this:

* put the file on the same server and use normal include directives
* use the file_get_contents or an iframe to load the external resource

Jassim Rahma11-Dec-11 21:44

11-Dec-11 21:44

I used file_get_conetnts and it's working fine except with some links but I don't know why..

if you check www.JassimRahma.com[^] you'll see all links are working perfectly under my domain but getting external page excet:

http://www.jassimrahma.com/16[^]

and:

http://www.jassimrahma.com/17[^]

both from http://www.telegraph.co.uk/[^]

what could be the reason?

This is not including. in php including is far different thing you are trying to do. all you need to use is html tag iframe and in the src attribute use the address.

error in login page

Hi,

can anyone help please.

I am getting this error:

Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in /home/jassimrahma/JassimRahma.com/admin/get_login.php on line 10

Warning: Cannot modify header information - headers already sent by (output started at /home/jassimrahma/JassimRahma.com/admin/get_login.php:10) in /home/jassimrahma/JassimRahma.com/admin/get_login.php on line 20

here is my code:

PHP

<?php
	session_start();
	
	$username = $_POST['username'];
	$password = $_POST['password'];

    $dbC = mysql_connect('mysql.jassimrahma.com', 'jassimdb', 'mujtaba');

The first warning is telling you that the value returned from mysql_query(), which you stored in $result is a boolean. This means that the query failed, because mysql_query returns FALSE when a SELECT query fails.

The second warning is telling you that it cannot output any headers, because it has already sent output to the browser - in this case, the first warning message.

You should check the return values from your database function calls. mysql_connect might have failed, or mysql_query could have failed for any number of reasons - use mysql_error[^] to find out what went wrong and fix it.

You should also sanitize all user input before building a query from it. Google for "sql injection" if you don't know what I'm talking about.

I got it... no database selected..

everytime I enter the correct user id and password it's just going back to login.php with no error message.

I am 1000000% sure about the user id and password, infact I added another uder and having the same problem.

user ID : abc123
Password : abc123

Okay... I won't try to guess which page is doing what wrong, but I will give you this handy code snippet:

echo '<pre>' . print_r(get_defined_vars(), true) . '</pre>';

If you insert that into a page where you think things are going wrong, it will dump all the variables into the page. I would try putting it before your if statement that does the redirects first, and see if $count is what you expect it to be.

You should turn on all errors and warnings when you are developing too:

ini_set('display_errors', 1);
error_reporting(E_ALL | E_STRICT);

plz help - htaccess
