header problem

what's wrong with this code.

if( urldecode($cat) == 'crib / toddler sheets'){ 
     header("HTTP/1.1 301 Moved Permanently"); 
     header("Location: http://www.mysite.com/mypage.php?pcat=21");
    echo "abc";
}

PHP:

I can see 'abc' printed on the page when I click this URL "mysite.com/product_listing.php?cat=crib+%2F+toddler+sheets". What should I do to redirect to mypage.php?pcat=21

 

Try this:

if( urldecode($cat) == 'crib / toddler sheets'){
     header("HTTP/1.1 301 Moved Permanently");
     header("Location: http://www.mysite.com/mypage.php?pcat=21");
     exit();
echo "abc";
}

PHP:

 

exit() did not work. blank page. Infact header() function is not doing it's job.

 

Set these lines on top.

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

PHP:

 

I have tried this. There is no Warning or Notice on the page. It is very strange type of error. I don't know how to fix it.

 

Where are you getting the value of $cat from ? Can you post the code that is above the code that you have posted.

Try this:

if( urldecode($_GET['cat']) == 'crib / toddler sheets'){
     header("HTTP/1.1 301 Moved Permanently");
     header("Location: http://www.mysite.com/mypage.php?pcat=21");
    echo "abc";
}

That doesn't seem to be the problem, as he gets the output of "abc" in this example.

Good point. How about echoing the result of urldecode($_GET['cat'])

That may give a clue where to look next.

This code is at top of the page. only database connection and session include file is above it.
nico_swd is right $_GET is not a problem. Problem is in header function. It's not working.

 

Just out of curiosity, what does this give you:

if (headers_sent())
{
    echo 'Headers sent!';
}

PHP:

 

Good Point. I am always getting 'Headers sent!' message. Now I put the following code on the top of the page above the connection include file. Now following lines are first 6 lines of page.

<?php if (!headers_sent()){
if($pcat == 5){
		header( "HTTP/1.1 301 Moved Permanently" ); 
		header("Location: mypage.php?pcat=38"); echo "abc";
	 }
}	 

PHP:

now i am not getting 'abc' printed on the screen.

It means header sent but what headers were sent?

 

There is a plugin for Firefox called Live Headers that will tell you what headers are sent.

Maybe your register global is off. Try

if($_GET['pcat'] == 5) { echo "abc"; }

PHP:

 

^^ No. Has been discussed earlier.

echo '<pre>' . print_r(get_headers('http://your-page.com/'), true) . '</pre>';

PHP:

Put the URL of the page you're having problems with there and see what headers you get.

 

I am getting Fatal Error:
Fatal error: Call to undefined function: get_headers()

I have also installed Firefox plugin but it's not helping. I am getting long list of headers.

 

Could you post a screenshot of that list?

And also, have a look if there's maybe a white space before the PHP opening tag. <?php

 

No there is no space before <?php tag.

Following are the headers by header plugin

 

Dear friends thanks for your time and help. I have found a solution.

put ob_start(); on the top of the page and ob_end_flush(); should be last line of code. Now its working but main question is still there that what was the problem with header() function.
