Question

我的add_comment.php有一个输入类型按钮，其值为“取消”，如果他按下取消，则不会将用户重定向到他想要评论的帖子。我添加评论按钮但效果很好。请告知。

<?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>

Answer 1

您需要在$ post_id

周围放置短标签

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

PHP没有重定向到所需的页面
