php - Using curl to submit/retrieve a forms results

I need help in trying to use curl to post data to a page and retrieve the results after the form has been submitted.

I created a simple form:

<form name="test" method="post" action="form.php">              
    <input type="text" name="name" size="40" />
    <input type="text" name="comment" size="40" />
    <input type="submit" value="submit" />
</form>

In addition, I have php code to handle this form in the same page. All it does is echo back the form values.

The curl that I have been using is this:

  $h = curl_init();

  curl_setopt($h, CURLOPT_URL, "path/to/form.php"); 
  curl_setopt($h, CURLOPT_POST, true);
  curl_setopt($h, CURLOPT_POSTFIELDS, array(
  'name' => 'yes',
  'comment' => 'no'
  ));
  curl_setopt($h, CURLOPT_HEADER, false);
  curl_setopt($h, CURLOPT_RETURNTRANSFER, 1);

  $result = curl_exec($h);
  echo $result;

When I launch the page with the curl code in it, I get the form.php page contents but it doesn't not show the variables that PHP should have echo'd when the form is submitted.

would appreciate any help with this.

Thanks.

AHHHH after your comment, the problem is clear.

you need to include one more POST variable in your array.

'submitted' => 'submitted'

the submit button also returns a post value if clicked, which you are checking in your form processing PHP.

if ($_POST['submitted']) {

in your curl code however you have left out the 'submitted' post variable.

if this is what you are looking for, please select the check mark next to this answer. thanks!
