Using a form to post to an external URL from within WordPress [closed]

Question

I'm trying to use a form to post data to an external URL, and I'm completely stumped by this problem.

The exact code I'm using is:

<form name="login" action="https://www.example.com/" method="post">
<input id="username" maxlength="50" name="username" type="text" value="username" onfocus="if(this.value == 'username') { this.value = ''; }"><br />
<input id="password" maxlength="50" name="password" type="password" value="password" onfocus="if(this.value == 'password') { this.value = ''; }"><br />
<input id="clientsubmit" type="submit" name="login" value="login"><br />
</form>

This code works perfectly in a blank html page, and logs me right in to the website I'm trying to log into. When I try to use the exact same code with a WordPress page, the page seems to refresh, and that's all I get.

I'd appreciate any help you guys might be able to give. I'm totally stumped on this one and I can only assume that it's a WordPress peculiarity.

You need to use curl to remotly login

Try this:

$myurl = 'myurl';
$details = array(
        'username'=> 'username',
        'password'=> 'password',
    'remember_me' => '1'
    ); 
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$myurl);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS,$details);
$page = curl_exec($ch);
echo $page;

//close connection
curl_close($ch);

Please Note:
You should check the fields value and match with
variables that are now called username & password..
