Problem with wp_insert_post

Question

i'm sorry for my english.

I have a problem with the function wp_insert_post in a script.

I'm trying to create a new post when i receive a notification from paypal. Everything works fine untill i try to create a new post in the database.

This is my code:

<?php include_once($_SERVER['DOCUMENT_ROOT'].'/wp-load.php');


            // Send an email announcing "received IPN"
            $mail_From = "[email protected]";
            $mail_To = "[email protected]";
            $mail_Subject = "received IPN";
            $mail_Body = $req;
            mail($mail_To, $mail_Subject, $mail_Body, $mail_From);

?>
<?php

// STEP 1: read POST data

// Reading POSTed data directly from $_POST causes serialization issues with array data in the POST.
// Instead, read raw POST data from the input stream. 
$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
  $keyval = explode ('=', $keyval);
  if (count($keyval) == 2)
     $myPost[$keyval[0]] = urldecode($keyval[1]);
}
// read the IPN message sent from PayPal and prepend 'cmd=_notify-validate'
$req = 'cmd=_notify-validate';
if(function_exists('get_magic_quotes_gpc')) {
   $get_magic_quotes_exists = true;
} 
foreach ($myPost as $key => $value) {        
   if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) { 
        $value = urlencode(stripslashes($value)); 
   } else {
        $value = urlencode($value);
   }
   $req .= "&$key=$value";
}


// STEP 2: POST IPN data back to PayPal to validate

$ch = curl_init('https://www.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));

// In wamp-like environments that do not come bundled with root authority certificates,
// please download 'cacert.pem' from "http://curl.haxx.se/docs/caextract.html" and set 
// the directory path of the certificate as shown below:
// curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem');
if( !($res = curl_exec($ch)) ) {
    // error_log("Got " . curl_error($ch) . " when processing IPN data");
    curl_close($ch);
    exit;
}
curl_close($ch);

// STEP 3: Inspect IPN validation result and act accordingly

if (strcmp ($res, "VERIFIED") == 0) {


            // Send an email announcing "enter in verified IF"
            $mail_From = "[email protected]";
            $mail_To = "[email protected]";
            $mail_Subject = "enter in verified IF";
            $mail_Body = $req;

I read about a problem with an infinite loop and maybe it's also for me because the script doesn't go on when try to execute the function.

Have you any ideas?

Answer 1

Because you mention an infinite I am guessing that you are hooked into a hook like save_post that fires for wp_insert_post() so if you hook your code into that your code will run then fire the same hook over and over.

To avoid that remove the action from the top of your callback:

remove_action('save_post','yourcallbackfunctionname');
$my_post = array(
    // ...
 );
 $post_id = wp_insert_post( $my_post, true );
