php - 如何在php中多次提交生成pdf

Question

我在面试中被问到一个问题。

Generate a PDF from multiple submissions. In the image you can see there is one form that contains name, email, phno, and country which will open one by one on click of "next" button and at last there is a "SUBMIT" button (slider I can use for next), which will generate the PDF containing all submitted data for that particular user.

Don't generate a PDF every time submit is clicked. Instead the user will fill out the form many times and than generate the PDF with all of the entries together in one PDF file.

例如我填写了这个类似的表格 5 次，最后我将生成所有组合数据的 PDF。

条件是不能存入Database，也不能存入session。

Answer 1

可以保存在cookie或者localstorage中的tmp数据，最后提交发送数据生成pdf
