[SOLVED] Cannot modify header information - headers already sent by...

[HowdeeDoodee]

I am getting this error message in one file but not another. How can I trace down the cause of this error message? No blank lines exist in this file outside of the php tags. Thank you in advance for your replies.

Post your code...there is also a bold sticky about this that you should read first.

Did you read the sticky at the top of this forum?

Color my face red, no I did not read the sticky. Shame on me.

 

Here is the full error message.

 

Warning: Cannot modify header information - headers already sent by (output started at /home/findt/public_html/CP/searchtest.php:65) in /home/findt/public_html/CP/searchtest.php on line 827

 

   $result = mysql_query($query) or die(mysql_error());
    $num_record = mysql_num_rows($result);
    $sql_num_rows = mysql_num_rows($result); 
    //echo "Number of effected rows: $sql_num_rows";
    if($sql_num_rows < (1))      
    {
echo "      No records were found.      ";
header("location: /CP/errorpage_norecords.htm"); 
    exit; 
    } 

 

Line 827 is the one beginning with "header" shown above.

 

The code is full of comments, so I will clean those out and see what happens. I thought there might be a troubleshooting method but perhaps not.

 

Thank you for the posts.

Remove...

 

echo "      No records were found.      ";

 

You cannot have ANY output before a call to header(). Why would you need to? Your redirecting anyway, makes no sense.

hey,

remove the echo statement or instead of header  write javascript to redirect

You are all correct on eliminating the echo statements. I had tons of them and was not aware of the header vs. echo issue. Although now it makes sense since an echo brings up a page. Thank all of you who posted. Freaks rule again!!!!
