base64 to pdf view gösterme – json jquery

merhabalar

elimizde bir çok faturanın listelendiği bir sayfa olsun. görüntüle diyince modal ile o pdf gösterilsin istiyoruz. base64 kodlarını da sayfaya doldurmak istemiyoruz. yapacağımız iş basit.

görüntüle butonuna onclick yazıp 1 değere faturanın modal idsi olacak. bu id, modal’ın bodysine yazdığın id. Unutma bunu. Onun yanında apiden base64 kodu almak için ya da neyse boşverin bunları.

ben size base64 kodunu pdfye dönüştüreyim sorunuz olursa iletirsiniz.

base = answer.base64x;
                       var base = "base64kodu";
                        $("<iframe width='100%' height='100%' />") // create an iframe
                            // add the source
                            .attr('src', 'data:application/pdf;base64,' + base)
                            .appendTo(viewid);

viewid, id değeri verdiğiniz herhangi bir div olabilir.

tablolar arası ilişkide sorguyu yazmadan otomatik gelmesini istiyorsak

laravel sürüme göre kurma (5-6-7-8 sürümünü kurma)

1
composer  create-project laravel/laravel yourNameProject  "8.*"

sondaki yıldız o sürümün en son versiyonunu belirtir. örneğin 8.* yıldızın karşılığı yanlış hatırlamıyorsam 8.6. Laravel 9 sonrası ihtiyaç olabilir diye yazıvereyim dedim. yoksa heryerde yazıyor zaten
