PHP - After Output_buffering On And Ob_start() Still Not Redirecting :-(

Hi,

this, i think, is a 'php in firefox' issue despite me mentioning css in the title so please read on!..

please have a look, using firefox, at http://www.laureleroch.com/gallery.php...

As you can see, when choosing different images via clicking on the thumbnails the page reloads and there's an amount of time where we see the page loaded without css applied..., however doesn't seem to be happening in IE9, opera, chrome, or safari. It IS happening in firefox on W7 and OSX.

the file gallery.php has...


<?php
session_start();
ob_start();
include("scripts/php/gallery_display.php");
include("scripts/php/file_reader.php");


...as its start...and...

 
</body>
</html>
<?php ob_flush() ?>

..at its end.

I can post all the code from the includes if required. I'd say there's a fair bit of processing done by these includes but really, not THAT much, plus other browsers seem to be doing ok with it.

Also, the background images are big. That's a fact. The site will be in this way and I plan to use a preloader once I get the main build sorted...nearly there.

One other thing...I really am a coding newbie. I've been toying with it for years, first with actionscript in flash, then html/css and now I'm getting really into php, however I'm sure my coding is pretty inefficient here and there thru nothing other than pure, undiluted ignorance...good, eh?!

so, if anyone got some pointers that would be really brilliant... any other info required - please shout.

cheers,

Scott

I am trying to use output buffering in the following manner:

Code: [Select]
ob_start("OB_BUFFER");
echo 'Start';
do_stuff_function();
ob_end_clean();
echo 'End';

The problem is that when the output of "do_stuff_function" exceeds 4k the output is automatically flushed and I don't know why (exceeding some limit I suppose). 

So when the output of "do_stuff_function" is less than 4k, I get this:

Code: [Select]
Start
My <4k output here...
End

When "do_stuff_function" exceeds 4k, I end up with this:

Code: [Select]
My > 4k output here...
Start
End

I don't understand why this is.  The docs seem to indicate that the way I am starting the ob_start() function there should be no buffer limit.  Is that not true?

Hi there,
I am trying to create a file using fwrite function, but for something reason all I get is a blank file with no content inside.
Here is the code, go to the bottom where the fwrite function is called:
<?php //Get Nohay Albums function
function GetAlbums($cattype){
    if ((isset($_GET['year']))||(isset($_GET['reciter']))){ //nothing displayed 
    }
    
    else{
        
    $query = "SELECT COUNT(Topic), SUM(Hits) AS totalhits, FileFormat, Speaker, Language, Year, FileType, Cat FROM nauhey WHERE Cat='".addslashes($cattype)."' AND Year='".date('Y')."' GROUP By Speaker, Year";
    $result = mysql_query($query) or die (mysql_error());

//<!------------ Create Cache -------------!>
//folder where cache is saved
$path = "cache/";
//Page name format: FunctionName_Category_Year.html
$pagename = $path."getalbums_".$cattype.".html";
$cacheFile = fopen($pagename, "w");
if ($cacheFile == FALSE){ 
    die ("Unable to create cache file"); }
    
//Get HTML in a variable
$obstart = ob_start();
if ($obstart == FALSE){ 
    die ("Unable to buffer cache content!"); }
//<!------------ Cache closed -------------!>

if ($cattype = strtolower('nauhey')){
    while ($row = mysql_fetch_array($result)){
    echo ("<div class='container'>");
    echo ("<img src=\"http://localhost/HAQMOLAAALI/backed up/haqmolaali/images/".$row['FileFormat'].".gif\">");

    echo ("<b style=\"font-size:10px; color:#000066; position:absolute; margin-left: 500px;\">DOWNLOADS: ".$row['totalhits']."</b>");
    echo (" <a href=\"nohay.php?reciter=".urlencode($row['Speaker'])."&amp;year=".urlencode($row['Year'])."\">".$row['Speaker']." Vol ".$row['Year']."</a> <b style=\"font-size:10px; color:#000000;\">(".strtoupper($row['Language']).")</b>"."\n");
echo ("<div class='small'><b>Year: ".$row['Year']." | Language: ".ucfirst($row['Language'])." | Tracks: ".$row['COUNT(Topic)']."</b></div>");
    echo ("</div>");
    }//while loop closed
        
        }
else {
    while ($row = mysql_fetch_array($result)){
    echo ("<div class='container'>");
    echo ("<img src=\"http://localhost/HAQMOLAAALI/backed up/haqmolaali/images/".$row['FileFormat'].".gif\">");
echo ("<b style=\"font-size:10px; color:#000066; position:absolute; margin-left: 500px;\">DOWNLOADS: ".$row['totalhits']."</b>");
echo (" <a href=\"majlis.php?reciter=".urlencode($row['Speaker'])."&amp;year=".urlencode($row['Year'])."\">".$row['Speaker']." Vol ".$row['Year']."</a> <b style=\"font-size:10px; color:#000000;\">(".strtoupper($row['Language']).")</b>");
echo ("<div class='small'><b>Year: ".$row['Year']." | Language: ".ucfirst($row['Language'])." | Lectures in series: ".$row['COUNT(Topic)']."</b></div>");
    echo ("</div>");
    
    }
        }
        
//<!------------ Cache Code -------------!>
$cacheContent = ob_get_contents();
//Write to cache file
fwrite ($cacheFile, $cacheContent) or die ("Cannot write cache content to file!");
fclose ($cacheFile);
ob_flush();
ob_end_clean();
//<!------------ Cache Closed-------------!>
    
    }
}

GetAlbums("nauhey");
?>

When I execute the function, I get my self-made error "Cannot write cache content to file!". Help would be much appreciated. Thank you.

Hey guys,

If my php looks like this: (notify if errors)

<?php

$user=$_POST['user'];
$pass=$_POST['pass'];

if(($user=="testing") && ($pass=="testing123")) echo "Access Granted";
if other echo "Access Denied!"

?>

If after the "Access Granted" It could redirect the user to another webpage, index2.html for instance.

Thanks in advance 

I do know that nothing should be printed out before a header() redirect, yet this error message:

Code: [Select]
Warning: Cannot modify header information - headers already sent by
Is pointing to a meta tag, why does a meta tag become considered as a print out?

The meta tags are as usually located in between the header tags of the whole website.

What would you rather recommend in this case to accomplish a redirecting after a successful log in?

Can Someone please look at the following zip file and edit index and code-gen so when someone refer required amount of visitors, php echo will redirect them to complete.php   I have got css and js but not uploading as they are too big   Thanks (please help me)    script.zip   29.95KB   3 downloads

As the title says, my headers not redirecting.

Login.php:
<?php

include("global.php");

if (isset($_POST['login'])) {

// Form data
$email = $_POST['email'];
$password = $_POST['password'];

// If email and password are both filled in
if ($email && $password) {

mysql_select_db("social_site") or die("Can\'t find database!");

$query = mysql_query("SELECT * FROM users where email = '$email'");
$numrows = mysql_num_rows($query);

// If email in database
if ($numrows != 0) {

// Login
while ($row = mysql_fetch_assoc($query)) {

$dbemail = $row['email'];
$dbpassword = $row['password'];

}

if ($email == $email && $password == $dbpassword) {

// User is logged in
header(' location: index.php ');

} else {

echo "Incorrect password.";

}

} else {

echo "That email does not exist.";

}

} else {

echo "Please fill in <strong>all</strong> fields.";

}

}

?>

<p>

Global.php:
<?php

mysql_connect('localhost', 'root', 'root');

?>

Any ideas?

Is it okay to redirect a user to another page - which displays an outcome message - after a form is submitted?


Debbie

For some reason the below is always redirecting to ./index.php?usercp=ideas&message=error

I'm assuming it's something to do with mysql_affected_rows.


<?php
session_start();
require_once 'db_select.php';
require_once 'func.php';
$donor_id=$_POST['donor_id'];
$donor_id=sanitize($donor_id);
$username=$_POST['username'];
$username=sanitize($username);
$name=$_POST['name'];
$name=sanitize($name);
$amount=$_POST['amount'];
$amount=sanitize($amount);
$idea_message=$_POST['idea_message'];
$idea_message=sanitize($idea_message);
$_SESSION['idea_message']=$idea_message;
$subject=$_POST['subject'];
$subject=sanitize($subject);
$_SESSION['subject']=$subject;
$confirm_agreement=$_POST['confirm_agreement'];
$confirm_agreement=sanitize($confirm_agreement);


if($subject==""){
$error0=1;
}
else{
$error0=0;
}

if($idea_message==""){
$error1=1;
}
else{
$error1=0;
}

if(($confirm_agreement!="no" && $confirm_agreement!="yes") || $confirm_agreement=="no"){
$error2=1;
}
else{
$error2=0;
}

$error="".$error0."".$error1."".$error2."";

if($error!="000"){
header("Location: ./index.php?usercp=ideas&error=".$error."");
}
else{
$sql="INSERT INTO $tbl_name5 (message_number, donor_id, username, name, amoutn, message) VALUES ('$message_number', '$donor_id', '$username', '$name', '$amount', '$message')";
mysql_query($sql);
if(mysql_affected_rows()==1){
header("Location: ./index.php?usercp=ideas&message=submitted");
unset($_SESSION['idea_message']);
unset($_SESSION['subject']);
}
else{
header("Location: ./index.php?usercp=ideas&message=error");
}
}
?>

why won't this header redirect?  it doesn't seem to like the mysql_close.  can i update the database before redirecting to another page?  is it possible?

Code: [Select]
<?php
session_start();
$name = "uname";
$lastLogin = date('l jS \of F Y h:i:s A');
require_once('../Connections/uploader.php');
mysql_select_db($database_uploader, $uploader); 
$query = "SELECT * FROM members WHERE uname='"
. $name . "'";
$result = mysql_query($query) or die(mysql_error());
// connect to database here
MYSQL_CONNECT($server, $user, $password) or die ("Server unreachable");
MYSQL_SELECT_DB($database) or die ("Database non existent");
if (mysql_num_rows($result) > 0) { 
$row = mysql_fetch_array($result) or die(mysql_error());
mysql_query("UPDATE members
SET lastLogin='$lastLogin'
WHERE uname='$name'")
// ERROR MESSAGE??
or die(mysql_error());  
mysql_close($con);
header('Location: redirect.php');
}

?>
thanks in advance.

i am trying to redirect a user to a certain page, if the credentials are not right.  if there is no session user, they are kicked out.  if it is set, but to the guest account, they go to the login page with a special error message.  here is my code for it:

Code: [Select]
if (!isset($_SESSION['user']))
{
  header('Location: portal.php?logintocontinue');
exit;
}
elseif($_SESSION['user'] == "guest") {
header('Location: portal.php?invalidLogin');
exit;
}
else {

}
after attempting to run the page, with session user = guest, i get this error message: The page isn't redirecting properly.

does it have to do with headers already being sent?

Hello,

I'm having some problems with a redirect situation.  I start on a page called Create Assignment.  From this page I pass (using GET) the variable assignment_id to a page called Add_questions (the user can add questions to this specific assignment).  When a user wants to add a question, they hit a link which brings them to my Database Update script.  All works great so far!  After the update, however, I want to redirect them BACK to the Add_questions page while keeping the same Assignment number.  I've tried using:
header('Location: list_assignment_question.php?assignment_id'); but I get this error:

Warning: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/algebra_book/main_scripts/db_insert_assignment_question.php:6) in /Applications/MAMP/htdocs/algebra_book/main_scripts/db_insert_assignment_question.php on line 12

Any thoughts?  I'd be more than happy to provide more code as needed.

Hi Guys,   I have a Url which allows me to send sms to a number. The url usually asks for id , number and few other things. When I paste the url in browser and press enter it opens and a sms is sent.   Now I want to code in php a way to send sms without redirecting to that page. For e.g. I ask user his mobile number and then I should be able to call/run that url and a sms should be sent to his number. If I use php header then it redirects to that page. I have tried using file_get_contents and php cURL but it has not worked so far.   Can you guys help me out ?   Thank you,   Cheers, GR

Is there anyway to do this:

my form is posting to self, then checking login creds. if they are incorrect it spits out "invaild bla bla" but if they are correct send them to a different page?

here is the short version of what I have.

if(isset($_POST['submit'])) {

//check inputs vs db

if ($check) {
header("Location: http://". $_SERVER['SERVER_NAME']."/include/process_renew.php");
} else { 
echo "<font color='red'>Username or Password did not match.</font> <br /><br />";
   }
}


}

I tested it using echo first and it worked fine then replaced the echo with header and now when I submit it just refreshes the page.

is this not possible?
