Create Form using Post Method in Django With Form- Validation


Create Form using Post Method in Django with  Form-validation:-

Post provides better security as compare to get because it will transfer data internally using CSRF (Cross-site request forgery) it will protect an application from cross-site scripting attack from the malicious site.

We will use method="post" attribute under the form tag in HTML Form and request.POST to get data of form element in

Example  of Post Method

Create using two different methods first is the load method to load the HTML page and second is the action method to implement logic.

from django.shortcuts import render
from django.http import HttpResponse

def index(request):    #load method
return render(request,"siapp/silogic.html")
def silogic(request):  #action method
return render(request,"siapp/silogic.html",{'res':si})

Create Design using Html file under the templates directory.

<!DOCTYPE html>
<style type="text/css">
background-color: gray;
width: 500px;
height: 35px;


width: 400px;
height: 35px;
background-color: orange;

<script type="text/javascript">
  function validate()
   p = document.getElementById("txtnum1").value;
   r = document.getElementById("txtnum2").value;
   t = document.getElementById("txtnum3").value;
    document.getElementById("spp").innerHTML="Enter P";
    return false;
    document.getElementById("spr").innerHTML="Enter R";
    return false;
    document.getElementById("sprt").innerHTML="Enter T";
    return false;


<form action="silogic" method="post">
{% csrf_token  %}
<input type="text" name="txtnum1" id="txtnum1" placeholder="Enter p" required="" /><span id="spp"></span>
<input type="text" name="txtnum2" id="txtnum2" placeholder="Enter r" required="" /><span id="spr"></span>
<input type="text" name="txtnum3" id="txtnum3" placeholder="Enter t" required="" /><span id="spt"></span>
<input type="submit" name="btnsubmit" value="Calculate" onclick="return validate()" />
