PHP - How To Add Expire Header In Js, Css, Images

did some searching on the internet and didnt find much.
i have created an online classifieds website and want all created listings to expire and delete after a certain amount of days.
honestly i have no idea where to start with this implementation. cookies were the only thing that even crossed my mind...
any ideas?
btw each listing is stored in a table called ob_listings

Assume this project is to create an online lottery system.

Is there a way to limit the user entering the numbers after a certain time?

E.g. The Draw will be at 9.00PM 05 November 2010 - Submitting the numbers will expire after 8.00PM 05 November 2010. (so any user tries to submit numbers after 8.00PM 05 Nov 2010 will not be entered in to the MySQL db).

Any help is highly appreciated.

Hello everyone, I'm just starting out with PHP as I need to create an online bookstore for a school project. I'm working by a magazine which should teach you exactly how to do this using PHP, but I've had a bunch of problems with the code they use and I don't really know what's going on. Anyway, this looks really simple and basically  what it does is allows you to post a comment on a book, then returns you to the book's page. Problem is, I'm getting the Header may not contain more than a single header, new line detected. error and I can't figure out why. I've tried researching into the matter but all the cases I found had to do with returning to an url, which is not my case.

Anyway, here's the snippet of code:

The form:

Code: [Select]
<div style="width:400px; border:1px solid #ffffff; background-color:#F9F1E7; padding:5px">
<b>Adauga opinia ta:</b>
<hr size="1">
<form action="adauga_comentariu.php" method="POST">
Nume: <input type="text" name="nume_utilizator"><br><br>
Email: <input type="text" name="adresa_email"><br><br>
Comentariu: <br> <textarea name="comentariu" cols="45"></textarea><br><br>
<input type="hidden" name="id_carte" value="<?=id_carte?>">
<center><input type="submit" value="Adauga"</center>
</form>
</div>
The script adaugare_comentariu.php:


Code: [Select]
<?php
ob_start();
include("conectare.php");
$numeFaraTags=strip_tags($_POST['nume_utilizator']);
$emailFaraTags=strip_tags($_POST['adresa_email']);
$comentariuFaraTags=strip_tags($_POST['comentariu']);
$sql="insert into comentarii (id_carte, nume_utilizator, adresa_email, comentariu) values(".$_POST['id_carte'].", '".$numeFaraTags."','".$emailFaraTags."','".$comentariuFaraTags."')";
mysql_query($sql);
$inapoi="carte.php?id_carte=".$_POST['id_carte'];
header("location:urldecode($inapoi)");
ob_end_flush();
?>
conectare.php connects to the mysql database. $inapoi is the variable which returns the user to carte.php (the book he posted a comment on), where id_carte is the book's unique id. I'm getting Header may not contain more than a single header, new line detected on line ten, which is the header line.

Can anyone help me? I've been stumped on this for a few days now and I've just let it pass and started working on other bits, but it's bugging me too much and I'd like to fix it. 

I have this script from http://lampload.com/...,view.download/ (I am not using a database) I can upload images fine, I can view files, but I want to delete them. When I press the delete button, nothing happens   http://www.jayg.co.u...oad_gallery.php   <form> <?php $dir = dirname(__FILENAME__)."/images/gallery" ; $files1 = scandir($dir); foreach($files1 as $file){ if(strlen($file) >=3){ $foil = strstr($file, 'jpg'); // As of PHP 5.3.0 $foil = $file; $pos = strpos($file, 'css'); if ($foil==true){ echo '<input type="checkbox" name="filenames[]" value="'.$foil.'" />'; echo "<img width='130' height='38' src='images/gallery/$file' /><br/>"; // for live host //echo "<img width='130' height='38' src='/ABOOK/SORTING/gallery-dynamic/images/gallery/ $file' /><br/>"; } } }?> <input type="submit" name="mysubmit2" value="Delete"> </form>   any ideas please?   thanks

Hey guys,

I have a problem, i'm using ob_start to send multiples headers and it works but the problem is that my metada is not being sent, when i remove the ob_start it gets sent. Is there a way i can allow more info to be sent with ob_start? or should i use other methods to redirect to pages? i dont want to use javascript or meta http because they are not very reliable is there any other way?
Thanks for help.

Hi there,

I have a form which displays a "successful" message if the form is completed correctly. However, I want the form to go to another url if it is successful. I have tried this, but I get the "headers already sent..." message


// Add New Subscriber Success Message
$successMsg = header('Location: http://www.example.com/');


is there another way to forward onto another page?

Thanks

How do I get this to put in the pilotID?

Code: [Select]
header("Location: logbook.php?id=" . $pilotid);
Thanks!

Hi everyone,
 
I have a login area, and i also have set up for me is a view page... the view page is each user's sort of profile, it gets id and displays relevant content.

i was wondering if i could get the id or post rather through a re-direct on log in?

for example user logs in with username and password,

user is re-directed to the view page like this:

header( "refresh:5;url=view00=id.php " );
echo '<h1>You will be re-directed in 5 seconds...</h1>';

user is taken to view page where they can edit bit on it.

So far though i'm getting page not found error? first of all is this possible? if not whats the correct way/better way?

Thanks

Hello!

I need a while loop that renders out part of my "header" redirect block.


<?php

header ('Location: /mylocation?'    /////this is where the header starts. however, for the rest of the header, it needs to be dynamic

$counter=1;  //I need to define some variables

while (babababa)   // and I need a while loop that renders out stuff for the header. 
{
Renders out stuff for the header
}

)     // and then finally i close the "header"

?>


However, apparently.. it's yelling at me for having dynamic stuff within the header.


Parse error: syntax error, unexpected T_WHILE in /var/www/ars/includes/common.inc(1699) : eval()'d code on line 18


So.... how would I put something dynamic, like a while loop or variables, within the "header" redirect block?

Thanks folks! Sorry if this is a bad question xD

I have a small program that is to be used to export data from some MYSQL tables into an Excel spreadsheet.

It does the export successfully, the first pass, but each subsequent download selection causes the browser to display the html code as text to the browser.

If I disable the excel output, the page redraws successfully un subsequent requests.

The header definition I have is ias follows:
Code: [Select]
$FileInfo = pathinfo(filename);
            // fix for IE catching or PHP bug issue
           
            header("Pragma: public");
            header("Expires: 0"); // set expiration time
            header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
            // browser must download file from server instead of cache
            // force download dialog
            header("Content-Type: application/force-download");
            header("Content-Type: application/octet-stream");
            header("Content-type: application/x-msexcel");
            header("Content-Type: application/download");
            // use the Content-Disposition header to supply a recommended filename and 
            // force the browser to display the save dialog.
            if ($download_filename == "")
                $download_filename = "download.xlm";
            header("Content-Disposition: attachment; filename=".$download_filename.";");
            header("Content-Transfer-Encoding: binary");
            header("Content-Length: ".filesize($filename));
            @readfile($filename);

I did not setup this header, because to be honest, these things confuse the heck out of me. Can anyone see what may be wrong with this? Can you give me some suggestions?

I can post more of the code if needed, but i believe that this is the area of interest for this issue.

Thanks in advance.

Hi guys,

I've got a header problem. I've read the header sticky post but i'm still not getting anywhere.

I am currently working on a registration form which loops though checking the data entered meets certain criteria by calling various functions (min length, max length, preg match, etc...), if anything returns 'false' then the form is reproduced with the error message of why it failed and what needs to be changed. If everything returned is 'true' then all day matches what is expected and the code then runs an 'insert' command. If the insert is successful then the code should forward the user to a new page displaying 'registration complete'.

However, the way I have written my code I am finding it near impossible to get the forward to be before anything is output to the browser therefore causing the header error. I have tried moving things around but i'm having no luck.

The error I am getting is:

Warning: Cannot modify header information - headers already sent by (output started at /websites/blahblahblah/register.php:6) in /websites/blahblahblah/register.php on line 77

The code there is relevant though as it is the code that make the connection to my DB.

if ( $_SERVER['REQUEST_METHOD'] == 'POST' )
{
$data= new check($_POST);

$data->name('forename');
$data->name('surname');

if ( $data->pass == true )
{
// Now we have the required data in the correct format do the code required to complete registration 

$forename=$data->input['forename'];
$surname=$data->input['surname'];

$query="INSERT INTO users ( forename, surname ) VALUES ('$forename' , '$surname' )";

if (mysql_query($query,$connect))
{
//echo "success";

// once data is inserted, go to complete page
header ("location: complete.php");
exit;
}
else
{
echo "Error: Please try again.";
}
}
}
else
{
$data= new check();
}
?>


What am I actually doing wrong and how can i possibly get the insert script higher up the code??

Thanks

the script below works but i have started getting this error
