PHP not redirecting to required page

Question

My add_comment.php has a input type button with value "cancel" its not redirecting the user back to the post on which he wants to comment if he press cancel .My add comment button however works perfectly .Please advise.

<?php  

 require_once 'app/helper.php';  
session_name('mypaperplane');
session_start();

 if (!verify_client()) {

    header('location: signin.php');
}

 $title='Add new comment';  
 $error="";

 if(isset($_POST['submit'])){


     $comments = filter_input(INPUT_POST,'comment', FILTER_SANITIZE_STRING);
     $comments = trim($comments);
     $post_id  = filter_input( INPUT_GET, 'id', FILTER_VALIDATE_INT );
     $post_id  = trim( $post_id );

    if (! $comments) {
         $error='*Comment field is required';

 }else{

     $com_link = mysqli_connect(MYSQL_HOST, MYSQL_USER, MYSQL_PWD, MYSQL_DB);
     $uid = $_SESSION['user_id'];
     $post_id = mysqli_real_escape_string( $com_link, $post_id );
     $comments = mysqli_real_escape_string( $com_link, $comments );
     $comsql="INSERT INTO comments VALUES('',$post_id,$uid,'$comments', NOW())";
     $comresult = mysqli_query($com_link,$comsql);

     if($comresult && mysqli_affected_rows($com_link)>0){

        header("location:readMore.php?id=$post_id");
     }else{

         header("location:readMore.php?id=$post_id");
     }
 }
 }
 ?>

 <div class="content">  

 <?php include'tpl/header.php'; ?>

     <form name="comment" method="post">
         <label for="comment">Comment here:</label><br><br>
         <textarea rows="15"  cols="15" name="comment" id="comment"></textarea><br><br>
         <input type="submit" name="submit" value="Add comment" onclick="window.location='readMore.php?id= <?= $post['id']; ?>';">  
         <input type="button" value="Cancel" onclick="window.location.href='readMore.php?id=$post_id'"><br><br>
         <span class="errorB"><?= $error; ?></span>

 </form>
       <?php include'tpl/footer.php'; ?>
             </div>

I'd need an account for that, try eval.in or https://pastebin.com/. — chris85, Apr 20 '17 at 01:09
You need to put `$post_id` in `PHP` blocks and echo it. The code went into the question for me. Not sure what you were encountering, might want to post that on https://meta.stackexchange.com/ if it is persistent for you. — chris85, Apr 20 '17 at 01:15

You need to put short tags around $post_id

'readMore.php?id=<?= $post_id ?>'
