我试图将多张图片上传到我的服务器,如果上传一张图片,我有以下工作,只是我不确定下一步要去哪里?
我有一个提交 3 张图片的 POST 表单,以下仅上传第一张,我需要为每张图片创建一个 while 循环吗?
到目前为止,我已经写...
$allowedExts = array("jpg", "jpeg", "gif", "png");
$extension = end(explode(".", $_FILES["file"]["name"]));
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/png")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000)
&& in_array($extension, $allowedExts))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br>";
echo "Type: " . $_FILES["file"]["type"] . "<br>";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";
if (file_exists("upload/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . date('U')."-".$_FILES["file"]["name"]); // add a unique string to the uploaded filename so that it is unique.
echo "Stored in: " . "upload/" . date('U')."-".$_FILES["file"]["name"];
}
}
}
else
{
echo "Invalid file";
}
谁能看到我哪里出错了?
