I would like to use CURL in order to fill in the username-password form
at the top right of this page http://www.lusa.pt/lusaweb/

I found the variable names in the page's code and tried the curl approach to
no avail (see below)...

Any suggestions ????

<form action="/lusaweb/dologin" method="post" name="frmLogin">
                <table height="100%" cellpadding="0" cellspacing="0" border="0">
                    <tr><td colspan="2" height="50%"></td></tr>
                    <tr>
                        <td align="right" class="login-text" nowrap="nowrap">&nbsp;&nbsp;Utilizador&nbsp;</td>
                        <td><input type="text" size="9" class="login" name="username" /></td>
                        <td>&nbsp;</td>
                    </tr>
                    <tr>
                        <td align="right" class="login-text" nowrap="nowrap">&nbsp;&nbsp;Senha&nbsp;</td>
                        <td><input type="password" size="9" class="login" name="password" /></td>
                        <td>&nbsp;<button type="submit" height="15" style="background-color:#C4201F;border:0"><img border=0 src="/lusaweb/images/go.gif" title="Autenticar"></button></td>
                    </tr>
                    <tr><td colspan="2" height="50%"></td></tr>
                </table>
                </form>

My attempt so far failing:

$url = "http://www.lusa.pt/lusaweb/"; // This page contains Login form 
  
        $postfields='username=toto&password=titi&action=/lusaweb/dologin'; 
        $ch=curl_init($url); 
        curl_setopt($ch,CURLOPT_RETURNTRANSFER,true); 
        curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true); 
        curl_setopt($ch, CURLOPT_POST, 1); 
        curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields); 
        $page=curl_exec($ch); 
         
        curl_close($ch); 
         
        echo $page;

Besides trying to use inside a php prog, I have also tried the following command line
curl http://www.lusa.pt/lusaweb/dologin?u...&password=titi
which returns a html file titled.... <title>An unexpected error occured</title>

Oddly enough, if I type that very same line into my browser, it works great and I log in!

It depends on how the site is setup, you might need to establish a user agent. Some sites want to make sure its a browser thats coming to the site and not a php script.

I have also heard others want cookies refrenced, not sure if that helps you on your way.
