thx for this example!
I check : coffee, tea, water .
result : only coffee
FC21, Firefox
It's really nice example!!
This used to work but the checkbox one only returns one value now for some reason. Using request.form.getlist('name_needed') is another way to retrieve multiple values from a form. Here is an alternate example:
from flask import Flask
from flask import request
app = Flask(__name__)
# Normally this would be an external file like object, but here
# it's inlined
FORM_PAGE = """
<html>
<head>
<title>Flask Form</title>
</head>
<body>
<form action="/process" method="POST">
<label>Name</label>
<input name="user_name" />
<br/>
<label>Age</label>
<input type="range" name="user_age" />
<br/>
<fieldset>
<legend>Drink preferences</legend>
<label>Coffee, Tea, water?</label><br/>
<input type="checkbox" name="drink_type" value="coffee" /> Coffee <br/>
<input type="checkbox" name="drink_type" value="tea" /> Tea <br/>
<input type="checkbox" name="drink_type" value="water" /> Water <br/>
<label>Temperature</label><br />
<input type="radio" name="drink_temp" value="hot" /> Hot <br/>
<input type="radio" name="drink_temp" value="warm" /> Warm <br/>
<input type="radio" name="drink_temp" value="Cold" /> Cold <br/>
<input type="radio" name="drink_temp" value="Iced" /> Iced <br/>

<input type="submit" />
</form>
