How to get the uploaded image name from the store method

问题

When I store an image in Laravel by doing:

$path = $request->file('myImage')->store('public/src/');

It returns the full path, but how do I get only the filename it was given?

This is an example of the returned path:

public/src/ltX4COwEmvxVqX4Lol81qfJZuPTrQO6S2jsicuyp.png

Here, you can try this one.

    $fileNameWithExt = $request->file('myImage')->getClientOriginalName();
    $fileNameWithExt = str_replace(" ", "_", $fileNameWithExt);

    $filename = pathinfo($fileNameWithExt, PATHINFO_FILENAME);
    $filename = preg_replace("/[^a-zA-Z0-9\s]/", "", $filename);
    $filename = urlencode($filename);

    $extension = $request->file('myImage')->getClientOriginalExtension();

    $fileNameToStore = $filename.'_'.time().'.'.$extension;

    $path = $request->file('myImage')->storeAs('public/src/',$fileNameToStore);
    return $fileNameToStore;

You will get your stored filename in $fileNameToStore. Also, all the spaces will be replaced with "_" and you will get your stored filename with current time attached with it, which will help you differentiate between two files with the same name.

In Laravel, the store() method generates the name dynamically .. so you can't get it from the store() method.

But you can use storeAs() method. Basically the store() method is calling the storeAs() method. So:

$path = $request->file('myImage')->store('public/src');

What Laravel is doing is calling ->storeAs('public/src', $request->file('myImage')->hashName()); .. you see the hashName() method? that is what generates the name.

So you can call hashName() first and know your name before the storing happens .. here is an example:

$uploadFile = $request->file('myImage');
$file_name = $uploadFile->hashName();
$path = $uploadFile->storeAs('public/src', $file_name);

Now you have $file_name and $path.
