Question

因此，我正在尝试将图像上传到数据库，以便可以将其用作用户个人资料图片，但是在单击“上传”后，什么都没有发生，这是代码：

viewHolder.txtSubject.setText("Example");

请先尝试此代码，然后以您自己的方式进行调整。链接：https://www.w3schools.com/php/php_file_upload.asp

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
    echo "File is an image - " . $check["mime"] . ".";
    $uploadOk = 1;
    } else {
    echo "File is not an image.";
    $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
    echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
    echo "Sorry, there was an error uploading your file.";
    }
}
?>

编辑并尝试

if((isset($_FILES['myfile']) || $_FILES['myfile']['error'] == UPLOAD_ERR_OK)) {
    $name=$_FILES['myfile']['name'];
    $tmp_name=$_FILES['myfile']['tmp_name']; 
    $location = "avatars/$name";
    move_uploaded_file($tmp_name, $location);       
    $query = mysqli_query("UPDATE esc_usuarios SET imagelocation='$location' WHERE usu_nome ='$usuario'");
    die("Your avatar has benen uploaded");
}

然后，这是upload.php中的整个代码吗？或在任何其他页面中？按照form action='upload.php'设置，这就是为什么要问......
