Php 我可以在桌面上上传图片和文件，但在手机上不行

我有一个单独的画廊和文件区。两者都可以在桌面上正常工作，但不能在移动设备上正常工作

画廊代码-每次只链接到无效的图像页面。即使在上传图像时也应该可以

    //When upload button is pressed
if (isset($_FILES['image']['tmp_name'])) {
    $image = date(U).$_FILES['image']['name'];
    $target = "gallery_images/".$username."/".$image;
    $sql = "INSERT INTO `images` (username, image) VALUES ('$username', '$image')";
    move_uploaded_file($_FILES['image']['tmp_name'], $target);
    mysqli_query($link, $sql);

    //checking to see if uploaded file is actually an image
    $file_type = image_type_to_mime_type(exif_imagetype($target));
    $allowed = array("image/jpeg", "image/jpg", "image/gif", "image/png", "image/svg+xml", "image/bmp", "video/x-flv". "video/mp4", "application/x-mpegURL", "video/MP2T", "video/3gpp", "video/quicktime", "video/x-msvideo", "video/x-ms-wmv");

    if(in_array($file_type, $allowed)){
        header("location:gallery.php");
    }else{
        header("location:invalid_file.php?img=$image");
    }
}

文件代码-将文件名上载到db，但实际上不会将文件放入指定的文件夹中

    //When uploadfile is pressed - file is stored in db and folder
if (isset($_FILES['file']['tmp_name'])) {
    if($_FILES['file']['name'] == $row["file"]){
        header("location:file_copy.php");
    }else{
        $file = $_FILES['file']['name'];
        $target = "file_storage/".$username."/".$file;
        $sql = "INSERT INTO `files` (username, file) VALUES ('$username', '$file')";
        move_uploaded_file($_FILES['file']['tmp_name'], $target);
        mysqli_query($link, $sql);
        header("location:files.php"); 
        }

请将我的正确代码与您的代码进行比较

<?php
$connection=mysqli_connect("localhost","root","","imgup");
if(isset($_POST['create_post'])){
    $post_image = $_FILES['image']['name'];
    $post_image_temp = $_FILES['image']['tmp_name'];
    move_uploaded_file($post_image_temp, "images/$post_image");
    $query = "INSERT INTO img(post_image) ";
    $query .= "VALUES('{$post_image}')";
    $create_post_query = mysqli_query($connection, $query);
}
?> 
<form action="fileup.php" method="post" enctype="multipart/form-data">       

        <label for="post_image">Post Image</label>
        <input type="file"  name="image">   
        <input type="submit" name="create_post" value="Publish">

</form>

日志中有错误吗？你的代码很奇怪。为什么保存文件后要检查文件类型？。您可以使用php的finfo函数来获取Mimetype@Akintunde它是这样写的，因为我是一个白痴谁匆忙！非常感谢你指出这一点，我现在就把它修好了。谢谢你的快速回复。我们将查看错误日志
