Php 为什么第二个move_upload_file函数没有'；你不能用这个密码吗？

如何在此代码中上载缩略图？
当我点击上传时，它只移动第一个上传的文件，不移动第二个。 有人能帮我吗

<?php
if(isset($_POST['submit'])){
    $cap = mysqli_real_escape_string($con, $_POST['cap']);
    $image = $_FILES['image'] ['name'];
    $tmp_name= $_FILES['image'] ['tmp_name'];
    $thumb = $_FILES['thumb'] ['name'];
    $tmp_name= $_FILES['thumb'] ['tmp_name'];
    $type = $_POST['type'];
    

    if(empty($image) or empty($thumb) or empty($cap)){
        $error = "<p style='font-seize: 20px; font-weight: bolder; color: red;'>
        Please Fill out all required stared inputs!</p>";
    }
    else{
        $pic = "INSERT INTO photos(image, thumb, caps, type)VALUES('$image', '$thumb', '$cap', '$type')";
        if(mysqli_query($con, $pic)){
            $success = "<p style='font-seize: 25px; font-weight: bolder; color: green;'>
            <i class='fa fa-smile-beam'></i> Your Data 
            Published Successfully</p>";
            move_uploaded_file($tmp_name, "img/photos/$image");
            move_uploaded_file($tmp_name, "img/thumbs/$thumb");
            
        }
        else{
            $fail = "<p style='font-seize: 20px; font-weight: bolder; color: red;'><i class='fa fa-sad-tear'>
            </i> Unsuccessful!</p>";
        }
    }
}
?>

一个变量只能包含一件事。您对图像和拇指都使用了
$tmp_name
，第二次赋值后，它只有拇指的临时名称

您需要使用不同的变量

<?php
if(isset($_POST['submit'])){
    $cap = mysqli_real_escape_string($con, $_POST['cap']);
    $image = $_FILES['image'] ['name'];
    $tmp_image= $_FILES['image'] ['tmp_name'];
    $thumb = $_FILES['thumb'] ['name'];
    $tmp_thumb= $_FILES['thumb'] ['tmp_name'];
    $type = $_POST['type'];
    

    if(empty($image) or empty($thumb) or empty($cap)){
        $error = "<p style='font-seize: 20px; font-weight: bolder; color: red;'>
        Please Fill out all required stared inputs!</p>";
    }
    else{
        $pic = "INSERT INTO photos(image, thumb, caps, type)VALUES('$image', '$thumb', '$cap', '$type')";
        if(mysqli_query($con, $pic)){
            $success = "<p style='font-seize: 25px; font-weight: bolder; color: green;'>
            <i class='fa fa-smile-beam'></i> Your Data 
            Published Successfully</p>";
            move_uploaded_file($tmp_image, "img/photos/$image");
            move_uploaded_file($tmp_thumb, "img/thumbs/$thumb");
            
        }
        else{
            $fail = "<p style='font-seize: 20px; font-weight: bolder; color: red;'><i class='fa fa-sad-tear'>
            </i> Unsuccessful!</p>";
        }
    }
}
?>

一旦移动，从原始位置复制肯定会失败。因为，嗯，它是从那里移动的。先复制，或者复制
img/photos/$image
@Barmar我的意思是，我怎么能同时移动两个图像？你能告诉我更多的细节吗？@mario那么我如何能同时将两个图像移动到一个目录中呢？你需要对这两个图像使用不同的变量。您正在使用
$tmp\u name
来表示这两个名称。
