How to attach a file using JS button(Laravel V8)?

To attach a file using a JavaScript button in a Laravel v8 application, you can create an input element of type file and trigger its click event when the button is clicked. Here's an example of how you can achieve this:

Create a button and a hidden file input element in your Blade file:

<!-- Your Blade file content -->
<button id="fileUploadButton">Upload File</button>
<input type="file" id="fileInput" style="display: none;">

Enter fullscreen mode Exit fullscreen mode

Write JavaScript code to handle the button click event and trigger the file input click event:

<!-- Your Blade file content -->

<!-- Your other HTML content -->

<script>
    document.addEventListener('DOMContentLoaded', function() {
        // Get references to the button and file input
        const fileUploadButton = document.getElementById('fileUploadButton');
        const fileInput = document.getElementById('fileInput');

        // Add click event listener to the button
        fileUploadButton.addEventListener('click', function() {
            // Trigger click event on the file input
            fileInput.click();
        });

        // Add change event listener to the file input
        fileInput.addEventListener('change', function() {
            // Once a file is selected, you can perform additional actions if needed
            console.log('File selected:', fileInput.files[0].name);
            // You can also submit the file using AJAX or a form submission here
            // Example: You can use FormData and send the file to the server
            // const formData = new FormData();
            // formData.append('file', fileInput.files[0]);
            // Use fetch or XMLHttpRequest to send formData to your Laravel backend
        });
    });
</script>

Enter fullscreen mode Exit fullscreen mode

Handle the file upload in your Laravel backend using routes and controllers.

This code sets up a button that triggers the file input dialog when clicked. Once a file is selected using the file input, the JavaScript code logs the selected file's name to the console. You can further extend the logic inside the change event listener to perform additional actions such as submitting the file to your Laravel backend using AJAX or form submission.

Remember to handle file upload securely on the server-side using Laravel's file handling mechanisms and validate the uploaded file before processing it. Also, customize this code as needed to fit your specific requirements and structure of the Laravel application.

I hope this information will be useful for you. If you have any questions please share with me.
