我有带有编辑功能的 Kendo UI Gridinline和我的一个领域 ( propertyLogo) 我使用kendoUpload上传图像。使用 kendoUpload 功能fileUploadEditor，我使用saveUrl: "./image.php",并将图像转换为base64格式以保存到数据库中。当我添加/编辑时，我设法成功更新了所有propertyLogo字段，但返回 NULL 结果的字段除外。我不知道我做错了哪一部分，但我无法将图像保存到数据库中。在这里，我将提供我的脚本。

图像将转换base64并存储到hexString变量中。一旦getPropertyMasterData.php被调用，它将获取hexString值。目前在这里我可以看到它成功返回一个值。
<?php
$file = $_FILES['fileUpload'];
$fileName = $_FILES['fileUpload']['name'];
$fileTmpName = $_FILES['fileUpload']['tmp_name']; //directory location
$fileSize = $_FILES['fileUpload']['size'];
$fileError = $_FILES['fileUpload']['error']; //default 0 | 1 got error
$fileExt = explode('.', $fileName); //split file name to get ext name.
$fileActualExt = strtolower(end($fileExt)); //change to lowercase for the extension file
$allowed = array('jpg','jpeg','png');
if (!in_array($fileActualExt, $allowed)) {
return ['error' => 'You cannot upload files of this type!'];
}
if ($fileError !== 0) {
return ['error' => 'Error occur when upload file!'];
}
if ($fileSize > 500000) {
return ['error' => 'Your file size is too big!'];
}
$fileDestination = './uploads/' . $fileName;
move_uploaded_file($fileTmpName, $fileDestination);
$data = file_get_contents($fileTmpName);
return ['hexString' => base64_encode($data)];

据说$uploadPayload['hexString']会从中获取一个变量，image.php但它以某种方式返回NULL结果。其他领域工作正常。

if (isset($uploadPayload['error'])) {
// echo $uploadPayload['error']);
/* do something in case of error */
}
$method = $_POST['method'];
switch ($method){
case "getPropertyMasterData" :
$method($ehorsObj);
break;
case "editPropertyMasterData" :
$method($ehorsObj, $uploadPayload['hexString']);
break;
default:
break;
}
