How do I pass user input from html to python?
Question
so I'm using bottle to connect my html and python code but I don't know how to take user input from my html code and use it as a variable in my python code. I have posted my code below, please help.
This is my bottle code
from bottle import default_app, route, template, post, request, get
@route('/')
def showForm():
return template("form.html")
@post('/response')
def showResponse():
return template("response.html")
application = default_app()
This is my main form which asks for the user input
<!DOCTYPE html>
<html lang = "en-us">
<head>
<title>BMI Calculator</title>
<meta charset = "utf-8">
<style type = "text/css">
body{
background-color: lightblue;
}
</style>
</head>
<body>
<h1>BMI Calculator</h1>
<h2>Enter your information</h2>
<form method = "post"
action = "response">
<fieldset>
<label>Height: </label>
<input type = "text"
name = "feet">
ft
<input type = "text"
name = "inches">
in
<br>
<label>Weight:</label>
<input type = "text"
name = "weight">
lbs
</fieldset>
<button type = "submit">
Submit
</button>
</form>
</body>
And this is my response code which displays a page when the user hits submit, I embedded my python code to be able to calculate the user's bmi
<%
weight = request.forms.get("weight")
feet = request.forms.get("feet")
inches = request.forms.get("inches")
height = (feet * 12) + int(inches)
bmi = (weight/(height^2)) * 703
if bmi < 18.5:
status = "underweight"
elif bmi < 24.9 and bmi > 18.51:
status = "normal"
elif bmi > 25 and bmi < 29.9:
status = "overweight"
else:
status = "obese"
%>
<!DOCTYPE html>
<html lang = "en-us">
<head>
<title>Calculation</title>
<meta charset = "utf-8">
</head>
<body>
<h1>Your Results</h1>
<fieldset>
<label>BMI : </label>
<input type = "text"
name = "BMI"
value = {{bmi}}>
<br>
<label>Status:</label>
<input type = "text"
name = "status"
value = {{status}}>
</fieldset>
</body>

It looks like you don't even attempt to access your form data in POST route. forms property of bottle.request object holds all parsed form data. Bottle documentation provides a good example on how to handle form data.
Also, it's really a bad idea to put logic into templates beyond what is needed for correct page rendering. You need to process data in your route or to move processing into a separate module for better separation of responsibilities.
