0:00 All right, so let's start off on our UI to implement 0:03 file uploads for our 0:04 products. We'll head back to our create product 0:08 modal, where we'll add a new input to actually 0:11 upload a product image. So open up our create product 0:15 modal, 0:17 and let's go ahead and create this new image 0:20 upload inside of our existing form. 0:23 I wanna add a new input that a user can click to 0:27 select a file on their operating system. 0:30 And once this file is selected, it'll be added to our form 0:34 data object automatically, since we're still inside of 0:38 a HTML form. So in order to do this, we're gonna 0:42 wrap our file input inside of a 0:46 material UI button. 0:48 So this importantly needs to have a specific component applied to 0:52 it, and this component is going to be the label. 0:56 So we're gonna supply this label component that's gonna be a button, 1:00 and this is for the file upload to work correctly. 1:03 It needs to have this label component. 1:06 We're also then gonna specify the variant of outlined to give it an 1:10 outlined look.

So go ahead and 1:33 add this cloud upload icon, and then make sure we 1:37 import cloud upload icon 1:42 from material UI icons material/cloud 1:46 upload. 1:49 All right, so now we're supplying this cloud upload 1:52 icon. 1:53 I want to actually now add the HTML input. 1:56 And the way we add a file selector is by adding a visually 2:00 hidden input. So this is gonna be a input that's invisible 2:04 to the user, but will capture the click event 2:07 and actually open up
