How to Download Files from a View in Laravel Without Navigation?

Downloading Files in Laravel Using Response::download

Many developers encounter challenges when attempting to allow users to download files within a view without navigation. This article addresses common issues and provides a solution.

Problem:
The file path "/public/download/info.pdf" does not exist, and the Download button navigates the user to a different view instead of initiating the download.

Potential Solution:

1. Correct File Path:

The first issue arises from the incorrect file path. Instead of "./download/info.pdf", you should specify the full physical path:

<code class="php">$file = public_path(). "/download/info.pdf";</code>

2. Avoiding Navigation:

To prevent user navigation, replace the button with the following:

<code class="html"><a href="#" onclick="downloadFile();" class="btn btn-large pull-right"><i class="icon-download-alt"></i> Download Brochure</a></code>

3. JavaScript Function:

Add a JavaScript function to handle the download:

<code class="javascript">function downloadFile() {
    var url = "/download";
    window.location.href = url;
    return false;
}</code>

4. Updated Controller:

Modify the controller to return the file with proper headers:

<code class="php">public function getDownload()
{
    $headers = ['Content-Type' => 'application/pdf'];

    return response()->download($file, 'filename.pdf', $headers);
}</code>

Note for Laravel 5 and Higher:

For versions 5 and later, use response()->download() instead of Response::download(). Additionally, the header array should be formatted as an associative array:

<code class="php">$headers = [
    'Content-Type' => 'application/pdf',
];</code>

By implementing these updates, the Download button will initiate the file download on the same view without navigating the user away.
