Getting undefined variable error when passing a PHP variable as a link on an anchor tag on the view

Am working on a Laravel application whereby I fetch some data from an API (which is an executable link which opens a PDF document when clicked). Am fetching the data storing in a variable then pass to the view but when I add it inside the href attribute of anchor tag I get error of Undefined variable: quotePdf.

But when I get the data after dd and paste it in the anchor link tag it works perfectly

AJAX code rendering the view

 $.ajax({
    type: "POST",
    url: "getquote",
    data: JSON.stringify(allData),
    contentType: "application/json",
    dataType: "json",
    cache: false,
    success: function(data){ 
      //The url that will render the view called quote.blade.php
      window.location.href="showquote" ;
    },
    error: function(data) {
        var errors = '';
        for(datos in data.responseJSON){
            errors += data.responseJSON[datos] + '\n';
        }
        alert(errors);
    }
});

Controller that fetches the code and shows on the frontend

 public function createQuote(Request $request)
    {

        $quote = $this->global_Curl_Meta(
            $data, 'api/travel/create-quote')->data;

        //dd($quote);

        $quote_data = $quote;

        $quoteholder_name = $form['FirstName'] . ' ' . $form['MiddleName'] . ' ' . $form['LastName'];
        $quoteholder_email = $form['email'];
        $travel_plan = $plan;
        $quoteID = $quote_data->QuotationId;
        $quoteRef = $quote_data->QuoteNumber;

        $data = [
            'sts_quote_number' => $quoteRef
        ];

        //STS PDF Quote
        $quotePdf = $this->global_Curl_Meta(
            $data, 'api/v1/travel/sts-quote-doc')->data;

        //dd($quotePdf);

        //Get all teh variables and return to the view
        $quote_data = view("B2C::travel.quote", compact('quote_data', 'quoteholder_name', 'quoteholder_email', 'travel_plan' ,'phone' , 'quotePdf' ));

        return 'true';
    }

Response on the browser after dd

The view that is called quote.blade.php being rendered via AJAX, all the variables are being rendered well except quotePdf

try this one

$quote_data = view("travel.quote", ['quotePdf' => $quotePdf])->render();

otherwise used with method

$quote_data = view("travel.quote")->with('quotePdf',$quotePdf)->render();

Try like this,

<a href="{!! $quotePdf !!}" target="_blank">Print Quote </a>

I may be wrong but this is what I have observed.

public function createQuote(Request $request)
            {

                $quote = $this->global_Curl_Meta(
                    $data, 'api/travel/create-quote')->data;

                //dd($quote);

                $quote_data = $quote;

                $quoteholder_name = $form['FirstName'] . ' ' . $form['MiddleName'] . ' ' . $form['LastName'];
                $quoteholder_email = $form['email'];
                $travel_plan = $plan;
                $quoteID = $quote_data->QuotationId;
                $quoteRef = $quote_data->QuoteNumber;

                $data = [
                    'sts_quote_number' => $quoteRef
                ];

                //STS PDF Quote
                $quotePdf = $this->global_Curl_Meta(
                    $data, 'api/v1/travel/sts-quote-doc')->data;

                //dd($quotePdf);

                //Get all teh variables and return to the view
                $quote_data = view("B2C::travel.quote", compact('quote_data', 'quoteholder_name', 'quoteholder_email', 'travel_plan' ,'phone' , 'quotePdf' ));

                return 'true';
            }

In your compact function, you are passing 'phone' as an entry which is not defined anywhere and hence it is ignoring each and every entry after that. Try to remove 'phone' from compact function.

Instead of returning to base64 string ($quotePdf) to view. You can do something like this.

$decoded = base64_decode ($quotePdf);

$pdf = fopen ('quote.pdf','w');

fwrite ($pdf,$decoded);

fclose ($pdf);

header("Content-type:application/pdf");

header("Content-Disposition:attachment;filename='quote.pdf'");

readfile("quote.pdf");

This code will decode base64 string and create a pdf file. and downloads the same. If you want return the view you can save the pdf in server and return the file path as a response.

Hope this helps!!
