how to access values passed by a submit button from a previous page?

Question

I have a form that has several checkboxes and text boxes whose values are all passed by one submit button to a different url. However, I am now trying to write the new url page but dont know how to access those values.

<form name="myform" action="result" method = "get">

        <fieldset>
            <input type="checkbox" value="total_money" name="check" onchange="javascript:toggle('money');" /> Filter by Total Money</br>

                <div id="money" style="display:none" name="option">  

                    <input type="checkbox" value="more" onchange="javascript:toggleLine('money_text');"  name="condition"/> <label for="condition" > > </label>

                        <div id = "money_text" style="display:none"  >
                            <input type="text" id="money_box" name="money_name" value="lower limit" />
                        </div></br>

                    <input type="checkbox" value="less" onClick="javascript:toggleLine('money_text1');" name="condition"/> <label for="condition1"> < </label>

                        <div id = "money_text1" style="display:none;"  >
                            <input type="text" id="money_box1" name="money_name1" value="upper limit" />
                        </div>

                </div>

            <input type="checkbox" value="employees" name="check" onchange="javascript:toggle( 'employees');"/> Filter by Employees</br>

                <div id="employees" style="display:none" name="option"> 

                    <input type="checkbox" value="more" onchange="javascript:toggleLine('employees_text');" name="condition"/> <label for="condition" > > </label>

                        <div id = "employees_text" style="display:none"  >
                            <input type="text" id="employees_box" name="employees_name" value="lower limit" />
                        </div></br>

                    <input type="checkbox" value="less" onClick="javascript:toggleLine('employees_text1');" name="condition"/> <label for="condition1"> < </label>

                        <div id = "employees_text1" style="display:none;"  > 
                            <input type="text" id="employees_box1" name="employees_name1" value="upper limit" />
                        </div>
                </div>                         
        </fieldset>
    <input type="submit" value="Submit" />
</form>

the url response that I get looks something like this (dependent on whats checked or not/input):

url:   http://127.0.0.1:8000/crunchApp/result?check=total_money&condition=more&money_name=lower+limit&money_name1=upper+limit&check=employees&employees_name=lower+limit&condition=less&employees_name1=upper+limit

I need to use this criteria as parameters for python methods that search a database but cant seem to figure out how. Any help would be greatly appreciated!

Are you using Django? CGI? How are you retrieving the data? Do you want to do this using AJAX? — cwallenpoole, Aug 24 '12 at 19:26

This could have been found with a little searching.

http://www.daniweb.com/software-development/python/threads/22312/get-posted-form-data-in-python

python cgi script--->addDo.cgi

import cgitb; cgitb.enable()
import cgi
import sys
form = cgi.FieldStorage()

// THIS IS WHERE THE VARIABLE IS READ FROM THE HTTP FORM POST
photos = form["photolist"]

i=0
for photo in photos:
    i = i + 1
    finalPhoto = finalPhoto + "," + photo[i]

sorry but I dont know what this means. This is a python script but I am trying to write the html page that reads the values given by another html page. Where would this code go/what does it do? – Santiago Aug 24 '12 at 00:24
You're submitting a form right? so you need to get POST variables. You can't do anything with just HTML on the receiving end of a post. You said you needed to get the variables into Python to query a database. Well, that's what this does. – FlavorScape Aug 24 '12 at 19:16

you could do this in bottle easily if you wanted to using something similar to this:

from bottle import route,request,static_file,template

@route('/mypage',method="GET")
def get_mypage():
    #return static_file('mypagetopost.html')  #you can use either static_file or template
    return template('mypagetopost.tpl')
@route('/mypage',method="POST")
def post_mypage():
    money_text=request.forms.get("money_text")  #you get the value of the form by getting it by name.
    #return "Your money_text text was:%s" % money_text
    return template('yourposttemplate.tpl',yourpostpagevarformoney_text=money_text) #you can pass variables to your template through returning the template, however you cannot do this with static_file

tweaking in your html page required: add: action="/mypage" method="post" to your submit.

Also note that in using the WSGI server with bottle by default, you need to setup static file handlers (for css/js/static html) and change your linking accordingly.
