A PDF is created and downloaded when the user submited a form. Usage: Create a Invoice, Create a certificate for the user etc. on form submission. Sample Website link

Requirement: 1. Free account in pdfgeneratorapi Overall Layout:i) PDF GENERATOR API ii) Wix code Backend (npm - pdf-generator-api) iii)Page Code iv) HTML Embed code (Convert Base64 into PDF file) i) PDF GENERATOR API1. Goto pdfgeneratorapi 2. Sign In and goto Dashboard 3. Select the "Template" on the left side bar 4. Click on the "New Template" button, A new window open to edit the pdf File 5. Design the PDF and to create a variable use open and close Curly brackets as shown on this image

[This is a image of the pdf generator Editor {Name} where the variable will be later assign using wix code And there is one more variable,{Detail} to add the message]

6. Publish the template and Goto the "Templates" from the Dashboard

7. Copy the Template Id from the "Templates"

8. Copy the APIKey and APISecret from the "Account Settings"

9. Copy the WorkSpace Identifier from the "Admin Panel"

ii) Wix code Backend

1. Search and Install "pdf-generator-api" npm (Check this link for Installation guide and Node package manager npm) 2. Create a Backend Web Module "pdf.jsw". 3. Copy and paste the code

import PDFGeneratorAPI from 'pdf-generator-api';

export async function pdf(name, detail) {
 let Client = new PDFGeneratorAPI(
 '<APIkey>',
 '<APISecrect>'
    );
    Client.setWorkspace('<WorkSpace identifier>');
 let obj = {
 "Name" : name,
 "Detail" : detail,
    }
 let response = await Client.output('<Template Id>', obj)
 return response.response
}

4. Replace the <APIkey> , <APISecrect> , <WorkSpace identifier> and <Template Id> to your corresponding value grab from the pdfgeneratorapi site 5. Create a object for the variable in this case i have create an object "obj" with two Key "Name" and "Detail" and the corresponding value directly from the parameter of this async function "name" and "detail" iii)Page Code1. Drag and drop Input element, Text box element and Button in a new page 2. Also Drag and drop the "HTML embed" element from "more" section 3. Change the Property name as shown in the image

4. Copy and paste the below code

	$w('#btnSubmit').onClick(() => {
		let name = $w('#inName').value;
		let detail = $w('#inDetail').value;
		pdf(name, detail).then(e => {
			base64 = e;
			base64 = 'data:application/pdf;base64,' + base64
			let msg = {
				"conv": true,
				"dataUrl": base64
			}
			$w('#html1').postMessage(msg);
		});
	});
});

iv) HTML Embed code1. Click on the HTML embed element 2. Click on "Edit code" button 3. Paste the following code

[updated 02-dec-2018]

                if(document.getElementById('Download') === null || document.getElementById('Download') === undefined){
                var pn = document.createElement('a')
                pn.download = 'Download.pdf';
                pn.title = 'Download pdf document';
                pn.textContent = 'Download';
                pn.id ='Download'
                var s = document.getElementsByTagName('body')[0].appendChild(pn);
                pn.href = event.data.dataUrl;
                } else {
                    let d = document.getElementById('Download')
                    d.href = event.data.dataUrl;
                }
               document.getElementById('Download').click()

Awesome tutorial! Is it possible to have the PDF be downloaded into a database, so you can connect it wherever you want on your site?

Salman2301

Dec 1, 2018

Thanks Brett, Wix only allow to upload files using "upload button" in the live site For now there is no other way upload files but there are some work around we can do 1. Using google cloud API to upload the Base64 into PDF and get back the pdf link and paste it on wix DB 2. Or simply saving the Base64 as a string on the wix Database

Salman2301

Dec 5, 2018Edited: Dec 5, 2018

Update on 5 DEC 2018 We can get back the URL directly instead of Base 64 and save it on the Database To do that change the backend code

 //BACKEND CODE
import PDFGeneratorAPI from 'pdf-generator-api';

export async function pdf(name, detail) {
 let Client = new PDFGeneratorAPI(
  '<APIkey>', 
  '<APISecrect>',
    );
    Client.setWorkspace( '<WorkSpace identifier>');
 let obj = {
 "Name" : name,
 "Detail" : detail,
    }
 let response = await Client.output(' <Template Id>', obj , 'pdf' , 'PdfName' , {"output" : "url"} )
 return response.response
}

There is no need of HTML embed element to convert Base64 into a PDF

//PAGE CODE
import { pdf } from 'backend/pdf.jsw';

$w.onReady(function () {
 var base64;
    $w('#btnSubmit').onClick(() => {
 let name = $w('#inName').value;
 let detail = $w('#inDetail').value;
        pdf(name, detail).then(e => {       //e="https://pdfgeneratorapi.com/share/3729/b2f8b6725fe4279cc4934b64734645e5"
            $w('#btnDownload').link = e;
            $w('#btnDownload').show();
            $w('#dataset1').setFieldValue('pdf', e);
            $w('#dataset1').save();
        });
    });
});

Salman Hello! I am currently developing a pdf button according to these explanations. Everything looks good so far, however, this isn´t clear enough to me on how to generate the link. The backend code should generate the link automatically? How does it work? Thank you for your amazing tutorials!

Is it available to send Pdf file to email after generation automatically?

Salman2301

Dec 31, 2018

Hello Yes, It's possible to send To do that you need a sendgrid account And use a the PDF in base64 Format Please refer this link on how to send an email using sendgrid platform written by myself https://support.totallycodable.com/en/article/send-a-template-email-using-sendgrid-npm-and-wix-code And this link for the code snippet

const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
  to: 'recipient@example.org',
  from: 'sender@example.org',
  subject: 'Hello attachment',
  html: '<p>Here’s an attachment for you!</p>',
  attachments: [
    {
      content: 'Some base 64 encoded attachment content',
      filename: 'some-attachment.txt',
      type: 'plain/text',
      disposition: 'attachment',
      content_id: 'mytext'
    },
  ],
};

Please, let me know if you have any question, Thanks

Hello.

Thanks for the information, in the PDF API Page the Free Account let me just 100 Merges, there is no other way? and, i see in other example you can generate a "print page example", do you have the guide or code?, i apreciate so much.

Thanks again.

Salman2301

Jan 15, 2019

Hello links_555, You will get 100 Merges per months for free account If you want more you can upgrade it. Right now i don't have the code or instruction for print pages I understand the demand i will write it when i have some time If you want immediately, I am available for hire.

Please send an email to

Hey,

Great work.

Can I insert a full table data into the PDF?

Thanks

Salman2301

Mar 6, 2019Edited: Mar 21, 2019

Yes, you can use a container element on the PDF generator API editor and send the Data as an Array with unique Id

code

let arr = [{
    "id" : "1",
     "textId" : "textValue 1",     
    },  {
     "id" : "2",
      "textId" : "textValue 2",
    }];
let obj = { 
       "containerId" :arr
       }

* containerId is the connected to the container * textId is connected to the text element attached to that container

@Salman2301 Hi Salman,

I tried to match an array with container or table in PDF Generator API, but I cannot find a way to name my container.

Thus, I'm not able to apply my array with an object. Could you explain me how to proceed or make a screenshot ?

This my page code :

let tableObjectifNm1 = $w("#tableObjectifNm1").columns

This is my backend code :

let obj = {

"TableObjectifNm1" : tableObjectifNm1,

...

Thanks

hi salmam, thanks a lot for this tutorial you saved my life the other day, but my client has requested a new feature to his wix page, he wants me to add an option to upload an image of 128x128 and add it to the generated pdf along with input text, so i want to ask you if that's possible and how to do it?

Salman2301

Jun 3, 2019

Hey Sorry for the late replay That's possible for user

Drag the image element

On the right site instead of link

set a variable

{imageUrl}

and on the backend file in wix site

you will need to pass the image url

let obj = {
 "Name" : name,
 "imageUrl" : "https://someimageurl.here",
 }

Happy coding!

Hi Salman, thanks for sharing this very useful info! I've tested this on my page but I get an error: (node:1) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.

Any thoughts on this?

Salman2301

May 23, 2019

I have hit the error too... I think i fixed by using .js file instead of .jsw You can even ignore it if it didn't cause a trouble Send me email with more detail salmanhammed77@gmail.com admin@salman2301.com

can you please tell me how can we print repaeter data using wix data..i am using wix data and unable to print using foreach loop

Salman2301

Jun 3, 2019

Hey Sharma,

You will need to use a container element in the pdf editor

https://docs.pdfgeneratorapi.com/#components-container

Select the container

on the right side

set the input variable anything

let say repeater

you will need to use a open and close curly brackets

{repeater}

and then on the backend file

pass and array of objects for the repeater varible

each objects must have id

like this

let obj = {
 "Name" : name,
 "repeater" : [{
     "id" : 1,
     "repeatingField" : "repeat1"
   },
   {
     "id" : 2,
     "repeatingField" : "repeat2"
   }],
 }

thank you

// i dont want to print that data like item[0] item[1] i want that data automatically comes using foreach loop and then i want to print that in the pdf. Because of array when i run that using foreach then if there are like 4 rows in the database then pdf dowloaded 4 times but i want to download that 4 items in in PDF. Because if in future someone add more rows than they automatically download in the pdf .beacuse the no of rows can be changed.

Please check once and please help me if it is possbile.

Sorry for bad english.

@Salman2301 Amazing tutorial, thank you. I have one question though. In my form I have an address input element which I want to include in the generated pdf. However, instead of the address being captured in the pdf, I have "array". How can I overcome this little issue?
