我正在尝试创建一个HTML和PHP脚本，以便从用户的手机上将图像上传到网络服务器。它工作得很好，它会提示用户从他们的图库中选择一个图像，或用他们的相机捕获图像。当我拍摄照片时，它会成功填写信息
“Foo.Jpg”
但是当我将数据传递到我的PHP脚本时，它给了我错误
“警告getimagesize（）文件名不能为空....抱歉，上传文件时出错。”
令我困惑的是，我的表单中的文件名不是空的。此外，当我使用台式计算机提交表单时（它只是提示文件上传），它可以完美地工作。
HTML：
<!DOCTYPE html>
<html>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" capture="camera" accept="image/*" name="imageFileToUpload">
<label for="rma">RMA: </label>
<input type="text" name="rma">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
PHP：
<?php
$rma = $_POST['rma'];
echo "RMA: " . $rma. "<br>";
$target_dir = "uploads/". $rma;
if (file_exists($target_dir)==false)
{
if(mkdir ($target_dir))
{
echo "folder created at: " .$target_dir . "<br>";
}
else
{
echo "failed to create folder " . $target_dir. "<br>";
}
}
$target_file = $target_dir ."/" .basename($_FILES["imageFileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"]))
{
$check = getimagesize($_FILES["imageFileToUpload"]["tmp_name"]);
if($check !== false)
{
//echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
}
else
{
echo "File is not an image.<br>";
$uploadOk = 0;
}
// Check if file already exists
if (file_exists($target_file))
{
echo "Sorry, file already exists.<br>";
$uploadOk = 0;
}
// if everything is ok, try to upload file
else
{
if (move_uploaded_file($_FILES["imageFileToUpload"]["tmp_name"], $target_file))
{
echo "The file ". basename( $_FILES["imageFileToUpload"]["name"]). " has been uploaded.<br>";
}
else
{
echo "Sorry, there was an error uploading your file.";
}
}
}
?>
到目前为止，我要感谢大家的善意和耐心的帮助，我感谢任何答案和指导。

它似乎永远不会发送图像类型或文件大小，只有使用移动设备时的名称。有任何想法吗？
