Question

这是功能测试输入：

function test_input($data) {
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;
}

我将网站切换到seo_url

news_url

news_url看起来像：

domain.com/title /

htaccess的网址是：

RewriteRule ^([a-zA-Z0-9_-]+)/$ detail.php?p=$1 [NC,L]

我的问题是，当我单击链接并转到帖子详细信息页面（detail.php）时，如果输入的网址正确，则找到正确的帖子。例：如果即将到达的网址是：

domain.com/test /

它可以正常工作，但是如果它的网址错误，例如：

domain.com/testt/

出现如下所示的错误，该行应将url重定向到错误页面，但不会重定向。

警告：无法修改标头信息-标头已由发送（输出从D：\ wamp \ www \ project \ heads \ nav.php：18开始） D：\ wamp \ www \ project \ detail.php在第57行

这是我的detail.php代码：

// Check existence of id parameter before processing further
if(isset($_GET["p"]) && !empty(test_input($_GET["p"]))){

    $seourl = test_input($_GET['p']);

    $stmt = $pdo->prepare("UPDATE posts set hits = hits + 1 where news_url = :news_url");
    $stmt->execute(array('news_url'=>$seourl));
    unset($stmt);

    // Prepare a select statement
    $sql = "SELECT * FROM posts WHERE news_url = :news_url";

    if($stmt = $pdo->prepare($sql)){
        // Bind variables to the prepared statement as parameters
        $stmt->bindParam(":news_url", $param_seo_url);

        // Set parameters
        $param_seo_url = htmlspecialchars($seourl);

        // Attempt to execute the prepared statement
        if($stmt->execute()){
            if($stmt->rowCount() == 1){
                /* Fetch result row as an associative array. Since the result set contains only one row, we don't need to use while loop */
                $row = $stmt->fetch(PDO::FETCH_ASSOC);

                // Retrieve individual field value  
                    $title = test_input($row["title"]);
                    $subject = test_input($row["subject"]);
                    $detail = $row["detail"];
                    $img = test_input($row["img"]);
                    $hit = filterNum($row["hits"]);
                    $keywords = test_input($row["keywords"]);
                    $id = filterNum($row["id"]);
            } else{
                // URL doesn't contain valid id parameter. Redirect to error page
                //This is not redirecting to error page 
                header("location: error.php");
                exit();
            }

        } else{
            echo "Oops! Something went wrong. Please try again later.";
        }
    }

    // Close statement
    unset($stmt);

} else{
    // URL doesn't contain id parameter. Redirect to error page
    header("location: error.php");
    exit();
}

和在nav.php中的代码错误提及：

                $place = filterString(1);
                $get_function = katplacegetir($place);
                foreach($get_function as $rowd){ ?> 
            <li><a href="category/<?php echo $rowd['seo_url'];?>/"><?php echo $rowd['cat_name'];?></a></li>
            <?php } unset($stmt);?>
            <?php
                $place = filterString(1);
                $get_function = postplace($place);
                foreach($get_function as $rowd){ ?> 
            <li><a href="<?php echo $rowd['news_url'];?>/"><?php echo $rowd['title'];?></a></li>
            <?php } unset($stmt);?>

问题解决了，伙计，谢谢，我进行了第二次查询 news_url是我删除了它的问题，现在一切正常。

如果isset获取验证网址，但不重定向到错误页面
