I have three dropdown filters on the front site to select country, territory and region and need to redirect the user to the country/territory/region page depending upon the filter values on click of Submit button.
FYI, I have pages with the same slug.eg- example/country-name/territory-name/region-name
I am trying to use wp_redirect( $final_url ); exit; but it is throwing a warning-
Warning: Cannot modify header information - headers already sent by (output started at E:\path\to\root-folder\wp-includes\class.wp-styles.php:154) in E:\path\to\root-folder\wp-includes\pluggable.php on line 1121
Please help.
Can someone suggest me some some better way?
//Edit- here is my code
if(isset($_POST['submit']) and $_POST['action']=='findurl')
{
//Result $POST Array ( [countrySelect] => 1 [territorySelect] => 1 [regionSelect] => 2 )
if (isset($_POST['countrySelect'])){
$rows_country_url = $wpdb->get_results("select url from country where id=".$_POST['countrySelect']."");
}
if (isset($_POST['territorySelect'])){
$rows_territory_url = $wpdb->get_results("select url from territory where id=".$_POST['territorySelect']."");
}
if (isset($_POST['regionSelect'])){
$rows_region_url = $wpdb->get_results("select url from region where id=".$_POST['regionSelect']."");
}
if($rows_country_url[0]->url !=''){
$final_url = home_url('/').$rows_country_url[0]->url;}
if($rows_territory_url[0]->url !=''){
$final_url = $final_url.'/'.$rows_territory_url[0]->url;}
if($rows_region_url[0]->url !=''){

if($final_url!=''){
wp_redirect( home_url() ); exit;

- Where are you using wp_redirect? You can't output any HTML and then call wp_redirect. It must be called before you output any content to the browser. Show some code. – Todd Rowan Commented Jun 27, 2014 at 8:35
- Hi Todd, I have edited my question to show the code. Please have a look. – user2443437 Commented Jun 27, 2014 at 8:54

Reset to default 1Please make sure these is no data output or blank spaces above wp_redirect( $final_url ); exit; otherwise this warning will always appear.
Also optionally you can use
<?php
//Php code
?>
<script type="text/javascript">
document.location.href="http://example";
</script>
<?php
//php code
?>
My solution is.
Create a function for javascript redirect.
function rm_redirect($url){ $string = ''; $string .= 'window.location = "' . $url . '"'; $string .= ''; echo $string; }
Call this function whenever you want like this.
rm_redirect('http://example');
