PHP - Cant Get This Cookie To Work Properly

I'm able to get the image file name in the database, the image to the right place BUT the problem is the image is totally black and after it's uploaded, a whole bunch of warnings appear.  Here are the warnings:

Hello,  I have one search form and when I search something the result is whole records from the database not only the search term. Any help is appreciated. I will post only the part where is calculating the rows from db but if need I will post whole pagination script. 

$searchTerm = trim($_POST['term']);
$adjacents = 3;

$sql1 = mysql_query("SELECT * FROM images ORDER BY id ASC");
$nr = mysql_num_rows($sql1);
$limit = 6;
$targetpage = "search.php";
$page = $_GET['page'];
if($page)
    $start = ($page - 1) * $limit;
else
    $start = 0;

if ($page == 0) $page = 1;
$prev = $page - 1;	 // $prev = $page - 1
$next = $page + 1;	 // $next = $page + 1
$lastpage = ceil($nr/$limit);   //lastpage = total pages / items per page.
$lpm1 = $lastpage - 1;
$pagination = "";
....
....
// pagination
...
...
// while loop for the results
$sql = "SELECT id, name, caption FROM images WHERE caption LIKE '%".$searchTerm."%' ORDER BY id DESC LIMIT $start, $limit";
$result = mysql_query($sql);
while($row = mysql_fetch_array($result))
{
    $output.= "<div class=\"container_image\">";
    $output.= "<a href=\"/pic-".$row['id'].".html\"><img src=\"/upload/".$row['name']."\" width=\"210\" height=\"150\"/></a>";
    $output.= "</div>";

I cannot get my script to update table: locations_all column city_state to the full state name.. Here's what I've been hacking at for 4.5 hours now! Ready to hit the sack.. Thanks for any input:

Hi guys, I have stuck with this issue for over 3 hours now. My remove all button just wouldn't work.   Can anyone tell me what's the issue? I have 2 pages, one parent and another pop-up page that takes the values (cartSubmit) from parent. And I wrote out the code for both pages but I just cannot get it to work.  I apologize in advanced if my code looks messy or doesn't make any sense.   Please take a look at the code and let me know if you could spot anything wrong with it. Any help is greatly appreciated.   Here is the code related to the remove all button in the parent page:

if(isset($_POST['finalSelected']))
{	echo "<br/>inside";
	if(!empty($_POST['fSelected']))
	{	echo "<br/>if NOT empty";
		$chosen = $_POST['fSelected'];
		foreach ($chosen as $item)
			echo "</br>aID selected: $item </br>";
		//implode function to transform an array to a string
		//chosen(array) to $delimit(String)
		$delimitStr = implode(", ", $chosen);
		//Save the selected String to SESSION
		if(!isset($_SESSION["final"]))
		{	
			$_SESSION["final"] .= "$delimitStr";
		}
		else
		{
			$_SESSION["final"] .= ", $delimitStr";
		}
		//Explode function to transform the SESSION variable back to an array for further trimming.
		$arraySession = explode(', ', $_SESSION["final"]);
		//Array unique to filter out duplicates.
		$uniqueArray = array_unique($arraySession);
		$cartSubmit = implode(", ",$uniqueArray);
		$_SESSION['cartSubmit'] = $cartSubmit;
	}
	else
	{
		echo "<br/>else empty";
		$noSubmit = $_SESSION["final"];
		//Explode function to transform the SESSION variable back to an array for further trimming.
		$arraySession = explode(', ', $_SESSION["final"]);
		//Array unique to filter out duplicates.
		$uniqueArray = array_unique($arraySession);
		$cartSubmit = implode(", ",$uniqueArray);
		$_SESSION['cartSubmit'] = $cartSubmit;
		
	}
}


<form name= "finalForm" method="POST" action="test6-1.php" target = "_self">
<input type="Submit" name="finalSelected"/>
<a href="javascript:popup('test6-3.php?aID=
<?php if(empty($_SESSION['final']) && empty($_SESSION['cartSubmit'])) echo "0";
else if(empty($cartSubmit)) echo "0"; else echo $_SESSION['cartSubmit'];?>')">Cart</a>


<?php if(isset($FinalName)) 
{ foreach($FinalName as $key => $item) 
	{?>
	<tr><td>
	<input type="checkbox" name="fSelected[]" value="<?php echo htmlspecialchars($FinalID[$key])?>" />
	<?php echo "$FinalID[$key] & $item";?>
	</td></tr>
<?php }
}?>
	</form>

And here is the code in the pop-up page.

<script> window.onunload = refreshParent;
function refreshParent() 
{
window.opener.location.reload();
}
</script>
if(isset($_POST['removeAll'])) 
{ $aID = "0"; 
unset($_SESSION['cartSubmit']); 
unset($_SESSION['final']); 
header("Location : test6-3.php?aID=0"); 
}

HI,
according to my knowledge session_destroy() function would destroy all session variables and mysql_close() would close connection with the database.
   i make a simply logoff.php file and close myssql connection and destroy session. but i still get values from the database and session variables. and doesnt work properly

here is the code
Code: [Select]
<?php
session_start();
/* 
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
require_once '../database/db_connecting.php';
$dbname="sahansevena";//set database name
 $con=  setConnections();//make connections use implemented methode in db_connectiong.php
 mysql_select_db($dbname, $con);
//update the time and date of the admin table
 $update_time="update admin set last_logged_date =CURDATE(), last_log_time=CURTIME() where username='$uname'limit 3,4";
 //my admin table contain 5 colums they are id, username,password, last_logged_date, last_log_time
 $link= mysql_query($update_time);
 // mysql_select_db($dbname, $link);
//$con=mysql_connect('localhost', 'root','ijts');

       $result="select * from admin where username='a'";

        $result=mysql_query($result);
mysql_close($con);
//here i just check after closing data baseconnection whether i do get reselts but i do, why?
echo "after the cnnection was closed";
  echo "<html>";
echo "<table border='1' cellspacing='1' cellpadding='2' align='center'>";

session_commit();

echo "session and database are closed but i still get values".$_SESSION['admin'];

I am currently creating a multi-user login system, and I have created the database in MySQL, but the problem is that my PHP script is not working as expected. I would like it so that if the user enters in a correct username + password combination, then they are redirected to a webpage called "congrats.php" for example. However, with my current PHP code, if I include a redirection instruction based on the correct input, then when I run the script, then the user is instantly taken to the congrats.php page without filling in any login details. I'm quite sure that the database has been connected to, as due to the layout of my script at the moment, the text that reads "You did it!" appears 4 times, the same number of rows in my MySQL database. My PHP coding for this is:

Code: [Select]
<html><head><title>Multi-User Log In Form</title></head>
<body>
<?php
$self = $_SERVER['PHP_SELF'];
$username = $_POST['username'];
$password = $_POST['password'];
?>
<form action = "<?php echo $self; ?>" method = "post">
Username <input type = "text" name = "username" size = "8">
Password <input type = "password" name = "password" size = "8">
<input type = "submit" value="Submit">
</form>
<?php
$conn = @mysql_connect("localhost", "root", "") or die ("Err: Conn");
$rs = @mysql_select_db("test3", $conn) or die ("Err: Db");
$sql = "select * from users";
$rs = mysql_query($sql, $conn);
while ($row = mysql_fetch_array($rs)) {

$name = $row["uname"];
$pass = $row["pword"];
if ($username = $name && $password = $pass)
{
//CODE FOR REDIRECTION SHOULD GO HERE
//header("location:congrats.php");
echo "You did it!";
}
else
{
echo "Invalid username and password combination";
}
}
?></body>
</html>

Any help in trying to get it so that my PHP script will redirect only if a correct username + password combination is entered would be greatly appreciated

This one requires lots of up front information:

I have a page, for this example that I will call page.php. It takes get parameters, and for this example I'll call the parameter "step". So I have a URL like this: page.php?step=1 This page has a form with an action of page.php?step=1. The code on the page validates the posting information. If the information is bad, it returns the user to page.php?step=1; if it is good, it takes the user to page.php?step=2 via header( "location:page.php?step=2" ). So redirection is done by relative path, not full URLs.
This all works as expected.

Now what I've done is set .htaccess to be HTTPS for this page, via this code:

# Turn SSL on for payments
RewriteCond %{HTTPS} off
RewriteCond %{SCRIPT_FILENAME} \/page\.php [NC]
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

This works (initially). However, once you try to post the form, it just redirects back to the step=1 version of the page. I really don't know how or why that would be.

I'm not sure how else I can explain this or what other information you may have. But it's frustrating to not get a page working in HTTPS that works in HTTP. Very odd. Any suggestions? (I don't even really know the best location to figure out when/why it's redirecting back to the original page.)

Hi..,
I use below method to export data to excel.

header('Content-type: application/ms-excel');
header('Content-Disposition: attachment; filename=abc.xls');

if I run the script from the server. (http://localhost/export.php) it is work. (pop-up window if i want save or open the file)

but if i run the script from the client (http://192.168.1.5/export.php) it is not work. (nothing happen)

any idea how to solve this?

require_once 'includes/upload.class.php';
$upload = new uploads();
$details = $upload->getFileInformation($id);

<?php echo $details['upload_desc']; ?>

then here the class.

require_once 'db.class.php';



class uploads extends database

{

   private $uploadData;

   function uploadFile() {

   public function getFileInformation($id)

   {

      $this->uploadData = $this->readData("uploadfiles", "upload_id", $id);

      return $this->uploadData;

   }


But it wont work!
      

i want to store the nickname of the user as a cookie..
somthing like set cookie name=nickname,value=smarty,expires after 1 week
i know cookies are stored against domain names.
what happens when another person logs in the same computer, with different login, and his nickname is diff
how does the cookie get handled, and how does the right nickname flash against the right persons login id...

Hey PHPFreaks!

I have a problem with my login script, because when i login it sets a cookie and it all works. But when i got redirected and refresh the page, my script turns an error which says i'm not logged in? how come?

This is what finds the cookie and redirects me

Code: [Select]
if(!isset($_SESSION['auth']) && !isset($_COOKIE['authcookie'])) {
        $_SESSION['ERROR'] = 7;
        header('location: index.php?login');
    }

I have part of my script that I have used many times in many diffrent applications that works just fine.
But in this use it refuses to set the cookie or do anything besides the redirect for that matter.
// if login is ok then we add a cookie 
  $ip = $_SERVER['REMOTE_ADDR'];
$datem = date("j F Y, g:i a");
mysql_query("UPDATE YBK_Login SET date = '$datem' AND ip = '$ip' WHERE ID = '{{$info['ID']}'")or die(mysql_error()); 

   $_POST['username'] = stripslashes($_POST['username']); 
   $hour = time() + 3600; 
 setcookie('ID_WatsonN', $_POST['username'], 0); 
 setcookie('Key_WatsonN', $_POST['pass'], 0);
 setcookie('UID_WatsonN', $info['ID'], 0);
 setcookie('LOGIN', $info['ID'], time()+3);
 //then redirect them to the members area 
  Header("Location: dashboard.php"); 

Hi all,

I'm struggling with a program I'm trying to write with cookies, so any help would be very much appreciated!!

What I'm wanting to do is when someone visits my site, I want to display content until the end of the day, and once the days up it disappears forever/until the cookies are deleted.

Could someone help me with this?

Thanks lots in advance,

Jake
