HomeBackend DevelopmentPHP Tutorial在帖子里面发表回复以后 点击一下返回后回不到帖子列表页是怎么回事?

我做的一个贴吧的效果  在帖子内容页点击返回可以直接返回到帖子列表页   但是如果提交回复内容后点返回却回不到帖子列表页 需要再点一次才能回去  如果提交两次回复需要按三次返回才能回到帖子列表页  提交回复次数越多需要按返回次数越多 这是怎么回事呢?


回复讨论(解决方案)

没看到代码,不好说

就是前几天一直问的那个代码?

如果你是用form表单,提交后相当于进入一个新页面了,点一次返回还是原来的页面
改成ajax异步提交就能达到你想要的效果了

就是下面的代码   这个是帖子主页  就是在这个页面提交内容后 点击一次回不到帖子列表页 

tieba3.php
;
nbsp;html>







include "cookie.php";
?>


  

      $pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
    $title=$_GET['id'];
    $stmt=$pdo->prepare("select id,title,content from topic where id=?");
    $stmt->execute(array($title));
    $res=$stmt->fetchall(PDO::FETCH_ASSOC);
    foreach($res as $v){
      echo ''.$v['content'].'';
    }
  ?>
     $pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
   $id2=$_GET['id'];
   $stmt=$pdo->prepare("select id,reid,content from reply where reid=?");
   $stmt->execute(array($id2));
   $res1=$stmt->fetchall(PDO::FETCH_ASSOC);
    foreach($res1 as $v2){
      echo $v2['content'];
     }
   ?>
  

  

    


     ">
     " >
      
      
  

  





tieba4.php
if(isset($_POST['reid'])){
  $pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
 $stnt=$pdo->prepare("insert into reply(reid,name,content)values(:reid,:name,:content)");
 $stnt->execute($_POST);
header("location:http://localhost/tieba3.php?id=".$_POST['reid']);
}
?>

header("location:http://localhost/ tieba3.php?id=".$_POST['reid']);
而 tieba3.php 显然是内容页而不是列表页

header("location:http://localhost/ tieba3.php?id=".$_POST['reid']);
而 tieba3.php 显然是内容页而不是列表页



对啊  这只是一个插入到数据库的页面  回复提交到当前页面 提交后并且显示出来   就是这么一个页面  比如我发表回复以后想返回到帖子列表页面  点击一次后退按钮却回不到帖子列表页面

你把 tieba3.php 改成列表页的程序文件不就行了?

那样效果就变了啊

我不懂异步提交啊  所以不懂它是怎么实现的 不是知道是不是我想要的效果

3楼的人已经回答你了,如果你点的是浏览器的返回当然退回到上一次的页面——就是你提交之前的页面。如果你点击的是自己写的返回按钮,那就是那个返回按钮的跳转链接不对
