PHP 上传带有给定名称的图片
PHP Upload image with given name
我正在使用此功能上传图片:
<?php
session_start();
if(!isset($_SESSION["user"]) or !is_array($_SESSION["user"]) or empty($_SESSION["user"])) {
// redirect to login page
}
$target_dir = ('users/'.$_SESSION["user"]["id"].'/');
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
// Check if file already exists
// Check file size
// 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 header('Location: main.php');
}
}
?>
如何将文件名更改为:profilepicture
例如。作为上传图像的任何用户,它被上传到用户 ID 文件,但使用实际图像的名称,而不是个人资料图片。
您可以更改以下行:
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$_FILES["fileToUpload"]["name"] 是原始文件名,因此将其更改为:
$target_file = $target_dir . 'profilepicture.'.pathinfo($_FILES["fileToUpload"]["name"], PATHINFO_EXTENSION);
