Hi guyz i am getting an error on my header information..the warnig is displayed
when this part of code Runs

echo '<a href="' . 'ecomm_catalogue_view.php?product_code=' . $product_code .'" >'; '</a>';
            header("location: ecomm_catalogue_view.php?' . 'product_code=' . $product_code . '");

the warning displayed on top of each page is:

Warning: Cannot modify header information - headers already sent by (output started at \romajir\search.php:19) in C:\xampp\htdocs\romajir\search.php  on line 20

i dont know how to solve this any suggestion would help..thanx in advance
the search code for search.php is

include 'db.inc.php';
$db = mysql_connect(MYSQL_HOST, MYSQL_USER, MYSQL_PASSWORD) or
die ('Unable to connect. Check your connection parameters.');
mysql_select_db(MYSQL_DB, $db) or die(mysql_error($db));

$search= (isset($_POST['search'])) ? trim($_POST['search']) : '';
if (isset($_POST['submit']) && $_POST['submit'] == 'Go') {
    if (empty($search)) {
    echo 'Their is Nothing to search!!';
    else {
        $query = 'SELECT product_code FROM ecomm_products WHERE name = "' .
        $search . '"';
        $result = mysql_query($query, $db) or die(mysql_error());
        if (mysql_num_rows($result) > 0){
            $row = mysql_fetch_assoc($result);
            echo '<a href="' . 'ecomm_catalogue_view.php?product_code=' . $product_code .'" >'; '</a>';
            header("location: ecomm_catalogue_view.php?' . 'product_code=' . $product_code . '");
            echo 'We don\'t have that product. Sorry...';
            $search = '';

You can send header after soemthing is ECHOed. Place the header statements above all echo statements and also make sure that there arent any blank lines or spaces.

header statements can be placed after echo statements.
check there isn't even a space before first <?PHP
also try


brackets are important.

@shubhamjain, once i place it on top of the echo still it doesnt work..& where should i remove the space...i can't see any spaces within my code

@metalix i have done as u hve told me but now it doesnt move to the other page!!

header("location: ecomm_catalogue_view.php?' . 'product_code=' . $product_code . '");

you are mixing quotes

header("location: ecomm_catalogue_view.php?product_code=$product_code");
header('location: ecomm_catalogue_view.php?product_code='.$product_code);

i think this is your problem

the general rule with quotes is that using "" doublequotes php will search through the string for things like $variable or $_SESSION or $var{$variable2}iable etc.
where as using ' ' single quotes they must be appended.
echo 'this is a '.$variable.' and a session'.$_SESSION;
you also need to close a text node you have opened.

'. . . product_code=' . $product_code . '");

after $product_code you opened another text node but closed with double quotes.
it is better to end without any quotes or $var.''
hope this helps :D

@metalix thanx i avoided using the code for ECHOing before the header and replaced tha header quotes with single quotes and it worked...thanx alot


No problems always glad to help :)
