Sample invoice pdf file download for corporations

hello guys welcome to filament daily we recently launched a new premium project on our filament examples.com combining three features generating PDF invoice then downloading the file from your browser or sending to a client to a customer and we wrapped those three features in this premium project which is available for members if you access all examples but traditionally on YouTube I summarize the things from premium projects into what you need to know how those features work generally so let's dive into the demo and into the code so this is the actual project you create invoice you fill in the form for example with filer Chrome extension for Simplicity we limited the invoice for just one line of price and product and we create the invoice created and then you have two buttons here download and send invoice if you click download here's the file downloaded here and here's how it looks as a PDF a very simple example nothing really fancy with design or anything because of course every PDF would be different for different invoice structure so your example for your project would be different our goal is just to show the principal and then you can also send the invoice via email to someone which in this case would be the email of the customer that you fill in here in the form so let's dive into the code how it works first generating of the invoice comes in two parts generating the data so database record with invoice number generated automatically and then the PDF generator and this both happens on eloquent level in laral outside of filament so filament resource doesn't change in terms of form submission but all the logic is in the eloquent model of invoice on booted method creating we create serial number for example this is just one of the possible logic options would generate the serial number from Max serial number with some string manipulation and add ABC as a prefix so this is done before the record is saved into the database creating is the method name not created this is important and then on create when the record is in the database already we do have that as invoice model object and then we generate a job which ideally comes to the queue because generating PDF usually takes a few seconds and then in the job inside we have this let's close the sidebar so you would see everything so we build that PDF from blade view which is invoice invoice which is HTML showing all the invoice data something hardcoded from your company data and then showing the price and the total and stuff like that in HTML and to produce PDF from that we use a library called if we go to composer Json Barry vdh laral Dum PDF you can use other PDF libraries like spoty browser shot or others but for simple invoices without too much customization ations I think this is good enough we generate the random file name and we store that and we update the invoice record in the database with the file name and then our job is completed so at this point again if we go into invoice model this takes care of the PDF generation and the model saving now download and send via email this is in the filament resource so we have invoice resource form is irrelevant for this video and in table actions we have two custom actions first download it's visible only if the file name exists which means that the Q job has successfully finished maybe it hasn't maybe there was some error and then the action itself is just response download file from Storage which means it's not public so you cannot access it just from typing some URL in the browser you can just download it from this action which should be of course protected by other roles and permissions and how it works in the browser you already saw a minute ago and then send invoice via email same logic for visibility and then mail to customer email and we have send invoice with record as a parameter and that send invoice is aailable and this uses the syntax which was introduced quite recently in Lal 10 from what I remember envelope content and attachments and here we have the attachment with the PDF that we generated just a few minutes ago so yeah this is an example of how you need to combine the knowledge of LL for stuff like mables like booted method in the the model like generating PDFs with a package like generating the invoice number and the prefix so all that is laral and then filament is just the layer to show those buttons and fill in the forms and to be honest I see more and more projects that we've been doing with the team and I see more questions on official filament Discord which are not that much about filament but whenever someone wants to customize filament more deeply they eventually bump into larl features this is just kind of my philosophical side note so this is the Practical example if you want the full source as usual it is available for members of filament examples.com you can access all examples so you would be invited to the GitHub for $99 per year we've changed the pricing recently it is yearly membership now or lifetime price is $1.99 for all the projects onetime payment and includes other future projects that we release on the same GitHub that's for this time and see you guys in other videos
