what am i doing wrong here?
<?php
include 'connect.php';
$query = 'SELECT productionorder.Finished FROM productionorder WHERE productionorder.ProductionOrderId = '.$id;
$result = mysql_query($query) or die ('Error : ' . mysql_error());
while($data = mysql_fetch_array($result)){
$status = $data['Finished'];
}
if($status == 1){
header('location: index.php?user='.$user.'');
}
else{}
?>
the query returns 1 and is going to else statement
please help me out here..
Jump to PostAre you sure the query returns 1? Test it with some code like:
if($status == 1) { die('Status is obviously 1'); // header('location: index.php?user='.$user.''); } else { die('Status is actually ' . print_r($status, 1)); }
Jump to PostSome questions that might help you:
- Maybe $status returns a string '1'.
- You write the query returns 1, but does $data['Finished'] also return 1.
- What value does $status have outside the while-block?
Good luck
Jump to Postso if i see this correctly i have to print somethign for the value to become 1 and not stay empty or whatever.

outside the while loop it returns 1.
tried it with quotes and without but i retrieve an integer from the database. so should not be a string.
$query = 'SELECT productionorder.Finished FROM productionorder WHERE productionorder.ProductionOrderId = '.$id;
$result = mysql_query($query) or die ('Error : ' . mysql_error());
while($data = mysql_fetch_array($result)){
$status = $data['Finished'];
}
if($status == 1){
die('Status = 1');
//header('location: index.php?user='.$user.'');
}
else{
die('Status = ' . print_r($status, 1));
}
returns:
"Status = 1"
so if i see this correctly i have to print somethign for the value to become 1 and not stay empty or whatever.

No, this was just a test. It might be that the location header is not getting the correct address or maybe some output has been sent before it (which prevents header for being sent). Remove the above debug code and try this:
if($status == 1) {
die('location: index.php?user='.$user.'');
//header('location: index.php?user='.$user.'');
} else {}
and check if the correct location string has been constructed and displayed.
Are you actually in the position to put an header? When something is already returned an header cannot processed anymore and if the according errormessage is supressed it may seem the else-path is choosen.
that returns location: index.php?user=123
just as expected since i'm logging in under user id 123
basicly the script test for a number of things before starting the script "start production" so it has some checks before and everytime 1 of those fail it should go to index.php?user=x
else it should do nothing. if i remove this it will go to a header on the next check anyway.
Then let's try if headers have already been sent:
if(headers_sent()) {
die('Headers have already been sent, you can not send them again.');
}
if($status == 1) {
die('location: index.php?user='.$user.'');
//header('location: index.php?user='.$user.'');
} else {}
updated the code and returns nothing
just a complete blanc screen.
seems like a typo or something.
headers_send() can;'t use the ()
and indeed i get the result "headers have already beens send cannor send again"
checked the code and header send is always in a if statement and always to index.php?user=x
so how do i not get to that page?
possible it has to do with nginx running??
You make sure no HTML output has been sent before any header() function. You can achieve that in several ways:
If sending an output before header() functions can not be avoided, use output buffering.
I met this message after I edited my code file with Visual Studio that added some invisible characters for ANSI format (or something alike) in the start of the file. When these were returned, the headers couldn't be send anymore.
run true all include scripts. and all it is returning in source code is "headers have already beens send, cannot send again".
So can you remove the output before the header function? If not sure, post the scripts.
here is the complete script, not just a piece of it:

First remove all the echo statements in the code since they send output too early. Some of them are not needed at all (since they are positioned after the redirection should happen). If this does not work check teh included scripts (or post them here). If you post the database connection script here, do not forget to remove password and other confidential data.
here is connect.php
<?php
$host="localhost"; // Host name
$username="root"; // Mysql username
$password='lalala123'; // Mysql password
$db_name="system"; // Database name
// Connect to server and select databse.
$n = 0;
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
Line 48 is incorrect:
if(headers_send)
It should be:
if((headers_sent())
Also make sure function.php script does not send output too early.
(headers_send()) wasn't working for me.
gave an error(white page)
and i think you mean
if(headers_send()) instead of if((headers_send())
function.php calls like 20 functions in different pages. but i don't use any of those functions so can't be it
Broj1 said:
if((headers_sent())
Not as you've said:
if(headers_send())
with or without the extra parentheses.
(headers_send()) wasn't working for me.
gave an error(white page)
If you only get a blank page when in error then first turn on error reporting and display of errors in php.ini. This would have helped in first place.
thanks for help broj1, i found out what the problem was.. the problem was i didn't define the timezone in the script before calling date()
this caused to output an error and didn't display it but this was the text before the header. now working.
indeed
