我试图将多张图片上传到我的服务器,如果上传单张图片,我有以下内容,但我不确定下一步该去哪儿?
我有一个提交3张图片的POST表单,以下只上传第一张图片,我是否需要为每张图片创建一个while循环?
到目前为止,我写过......
$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";
}
任何人都可以看到我出错的地方吗?
答案 0 :(得分:0)
如果您想使用脚本,可以通过以下方式完成:
for($i = 0; $i < 3; $i++) {
$aFile = $_FILES['file'][$i];
// your code ($_FILES['file']['tmp_name'] should be addressed like $aFile['tmp_name'] and so on..
}
