I'm currently developing a plugin for my page. The goal is to upload a custom profile image from a user page. Now I want to store each image under a pre-defined name. Sadly I've no plan how I can set a custom name for a file during the file upload with the WordPress function wp_upload_bits():
$filename = $_FILES['file']['name'];
$uploaded_bits = wp_upload_bits(
$filename,
null,
file_get_contents( $_FILES['file']['tmp_name'] )
);
Currently when I upload for example an image with the name yolo.png, the name stays yolo.png.
Now I want to define the new name this way:
$filename = 'profile-image-' . get_current_user_id();
But this can't work because the $_FILES['file']['name'] is the temporarily saved file on my server and this is yolo.png. So do you have any idea how I can reach my goal?
Today I'm not that smart. I need to pass the file type, otherwise the upload can't work...:
$filename = 'profile-image-' . get_current_user_id() . '.' . substr( strrchr( $_FILES['file']['name'], '.' ), 1 );
With this part of code I just get the file extension:
'.' . substr( strrchr( $_FILES['file']['name'], '.' ), 1 );
you can get the file extension also by splitting the string
$arr = explode('.',$_FILES['file']['name']);
$ext = end($arr);
you then concatenate the file extension with the name you want.
you could also try to the function
move_uploaded_file($_FILES['file']['tmp_name'], 'path/to/folder/'.$filename);
