Question

I want to show an error (in phpBB it’s trigger_error) right after the user clicks submit.

I already have a function which checks if a link has been posted. Now I want to call it after the submit post button has been clicked.

Where do I find that? Probably in posting.php?

Answer 1

Open posting.php.

find around line 631

    if ($submit || $preview || $refresh)
{

after add

  $post_data['your_url'] = "http://www.damienkeitel.com/index.php"; //remove the equals and url value if using in real post
  $your_url = $post_data['your_url'];
  $your_url_exists = (isset($your_url)) ? true : false;
  $your_url = preg_replace(array('#&\#46;#','#&\#58;#','/\[(.*?)\]/'), array('.',':',''), $your_url);

  if ($your_url_exists && http_file_exists($your_url) == true)
  {
    trigger_error('yeah, its reachable');
  }
  else if ($your_url_exists && http_file_exists($your_url) == false)
  {
    trigger_error('what da hell..');
  }

/**

after add

function http_file_exists($url) 
{ 
  $f = @fopen($url,"r"); 
  if($f) 
  { 
    fclose($f); 
  return true; 
  } 
return false;
