I am trying to cURL my university login page. I want users to enter their university id and pass in my website, my website will curl to university website, authenticate and then allow them to login or give error accordingly. But my university portal is a jsp page. And after having posted in StackOverflow and other forums before, this is what I came up with. I need further help on where I am going wrong and how to rectify it.

<form class="form-horizontal" action="curl.php" method="POST">
        <div class="control-group">
            <label class="control-label" for="inputEmail">Username</label>
            <div class="controls">
                <input type="text" id="inputEmail" placeholder="Username">
            </div>
        </div>
        <div class="control-group">
            <label class="control-label" for="inputPassword">Password</label>
            <div class="controls">
                <input type="password" id="inputPassword" placeholder="Password">
            </div>
        </div>
        <div class="control-group">
            <div class="controls">
                <label class="checkbox">
                    <input type="checkbox"> Remember me
                </label>
                <button type="submit" class="btn">Sign in</button>
            </div>
        </div>
    </form>


Now this is my curl.php file:

<?php
    $address = "http://evarsity.srmuniv.ac.in/srmswi/usermanager/youLogin..jsp"; //site URL
    $post = "username=txtRegNumber&pass=txtPwd"; //Parameters to be sent. Written like GET.
    $welcomeMessage = "Welcome..."; //This is the message that is displayed when a login is successful

    $options = array(
       CURLOPT_USERAGENT => 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)', 
       CURLOPT_POST => true, //using post
       CURLOPT_URL => $address,  //where to go
       CURLOPT_POSTFIELDS => $post, //input params
       CURLOPT_RETURNTRANSFER => true, //Returns a string value of the request
       CURLOPT_SSL_VERIFYPEER => false, //Avoid SSL problems
       CURLOPT_COOKIEFILE => 'cookie.txt', //Save cookies
       CURLOPT_COOKIEJAR => 'cookies.txt' //Cookies located
       CURLOPT_USERPWD ==> [username]:[password]); 


          if (strpos($content, $welcomeMessage) !== false){ 
          /*
          Do whatever,I don't know what to do here though
          */
          }

      curl_close($ch); //close connections
    ?>


Please let me know where I am going wrong, why I am not able to login and after logging in, how to log out.

Thank you.

There are quite many people who won't do that, login in to a site from a
third party page, as this can cause login credentials be stolen.

This don't make any difference how curl works.

[color=blue]>       $address = "http://evarsity.srmuniv.ac.in/srmswi/usermanager/youLogin.jsp"; //site URL[/color]
[color=blue]>       $post = "username=txtRegNumber&pass=txtPwd"; //Parameters to be sent. Written like GET.[/color]

You need to set the login name and password, in this case you just using 
static values txtRegNumber / txtPwd, you need to assign those dynamically.
See http://www.php.net/manual/en/language.variables.basics.php

[color=blue]>       $welcomeMessage = "Welcome..."; //This is the message that is displayed when a login is successful[/color]
[color=blue]> [/color]
[color=blue]>       $options = array([/color]

[color=blue]>          CURLOPT_USERPWD ==> [username]:[password]);[/color]
[color=blue]> [/color]

You need to make the connection to the site, see example at php.net:
http://www.php.net/manual/en/function.curl-init.php

[color=blue]>             if (strpos($content, $welcomeMessage) !== false){[/color]
[color=blue]>             /*[/color]
[color=blue]>             Do whatever,I don't know what to do here though[/color]
[color=blue]>             */[/color]
[color=blue]>             }[/color]

You should make error checks, see examples at php.net:
http://www.php.net/manual/en/function.curl-errno.php
http://www.php.net/manual/en/function.curl-error.php

When you confirm that you have logged in, you have to be sure that the 
string you look for don't include HTML tags.

[color=blue]>         curl_close($ch); //close connections[/color]
[color=blue]>       ?>[/color]
[color=blue]>  
[/color]

Drop the cookie, if you want the university web server to know it, make
a curl request to the logout link/page.


Good luck with your school assignment.

I am making this for my college out of my own interest after conducting a survey. So this is not my assignment and people said they won't sign up freshly and they wanted to login using existing ids and passwords provided by the university.
