Posting data with PHP cURL

Question

If there are 2 form fields in a page with 2 different submit buttons how do I tell to cURL which form to submit?

Example

<form method="post" action="index.php"> <input type="text" name="age"> <input type="submit" name="agree"> <input type="submit" name="disagree"> </form>

My code so far

//create array of data to be posted $post_data['age'] = '5';   //traverse array and prepare data for posting (key1=value1) foreach ( $post_data as $key => $value) {     $post_items[] = $key . '=' . $value; } $post_string = implode ('&', $post_items); curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string);

There is no needing to know which form in HTML must be posted.

Form can be determined by Method, Action and/or Set of fields.

P.S. Clicked named submits are sending too. So add post_data['agree'] = '';.

P.P.S. Don not use it for spam.

You can pass an array to CURLOPT_POSTFIELDS and let php's curl extension do the dirty work of encoding etc.

This saves you from encoding the string!

curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_data);

Yes but what about specifying which submission button to click?

$post_data['agree'] = 'Submit' where agree is either agree or disagree :)

Name of submit button is a key in $_POST array. Simply set it and specify some dummy value, e.g. "Submit"
