[英]PHP Upload image with given name
I am using this function to upload the image: 我正在使用此功能上传图像:
<?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');
}
}
?>
How would I change the file name to: profilepicture for example. 例如,如何将文件名更改为:profilepicture。 As any user that uploads an image, it's uploaded to the users ID file but with the name of there actual image, rather than profilepicture.
作为任何上传图像的用户,图像都将上传到用户ID文件,但带有实际图像的名称,而不是profilepicture。
You can change the following line: 您可以更改以下行:
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$_FILES["fileToUpload"]["name"] is the original filename, so change it to something like: $ _FILES [“ fileToUpload”] [“ name”]是原始文件名,因此请将其更改为:
$target_file = $target_dir . 'profilepicture.'.pathinfo($_FILES["fileToUpload"]["name"], PATHINFO_EXTENSION);
