wordpress - Cannot get wp_redirect to work -

i'm trying send email using wp_mail , then, if mail sent successfully, redirect user page (or, if not successful, error page).

my code shown below. email sent, wp_mail working, cannot redirect work.

<?php  /*  template name: redirect template */  ?>  <?php  $to = "info@some-domain.com";  $subject = 'this test.'; $message = 'this test of wp_mail function.'; $headers = '';  $sent_message = wp_mail( $to, $subject, $message, $headers);  if ($sent_message) {      $url_1 = "http://www.some-url.com";     wp_redirect($url_1);     exit();  } else {     $url_2 = "http://www.some-other_url.com";     wp_redirect($url_2);     exit(); }  ?>  <?php get_header(); ?>           <?php while ( have_posts() ) : the_post(); ?>              <?php get_template_part( 'content', 'page' ); ?>          <?php endwhile; // end of loop. ?>   <?php get_footer(); ?> 

you need rid of white space between closing , opening php tags. because have space, wordpress initiating output before redirect runs (which isn't allowed). rid of following @ top of file:

?>  <?php 

so top of file becomes:

<?php  /*  template name: redirect template */  $to = "info@some-domain.com";
