How to get image path in Laravel?

Question

Laravel

Hello. I have such a problem. There is a code that saves the data from the form to the database:

public function NewpostSubmit(AdminpanelRequest $postData) {
        $newpost = new NewpostModel();
        $newpost->title = $postData->input('title');
        $newpost->thetext= $postData->input('thetext');
        // $coverpath = $postData->file('uploadPostCover')->store('uploads', 'public');
        // $newpost->coverpath = $postData->input($coverpath);
        $newpost->save();

The two lines that I commented out are responsible for processing the image upload form. The first line, in fact, loads the picture into a folder, and the second, in theory, should write the path to the picture in mysql, but this path is not recorded in the database. How can this be corrected? Thank you.
