    • tiki-webmail.php line 420

    Posted by Tagg posts: 21 ☆ ☆ ☆ United States

    When visiting the webmail mailbox, I get two errors — the second of which is cascaded by the first:

    Image
    Copy to clipboard
    Notice: Undefined index:
 Date in .../tiki-webmail.php on line 420
Notice: strtotime():
 Called with empty time parameter in
 .../tiki-webmail.php on line 420

    The refenced code is:

    Image
    Copy to clipboard
    [LINE 420] $aux["timestamp"] = strtotime($aux['Date']);

    I used the PHP function print_r() to inspect what the $aux array contains. The culprit turned out to be the absence of a 'Date' record. Instead, the message header as parsed from qmail apparently replaces that with a 'Received' array.

    Image
    Copy to clipboard
    Array
(
 [Return-Path] => <ac...@ho...>
 [Delivered-To] => ac...@ho...
 [Received] => Array
 (
  [0] => (qmail # invoked by uid #); 2 Jan 2006 23:56:00 -0000

    My fix (yes, it works) is to check for the known header variants in order to extract the date value, as such:

    Image
    Copy to clipboard
    if (array_key_exists('Date',$aux))
{ $aux["timestamp"] = strtotime($aux['Date']);
} elseif (array_key_exists('Received',$aux))
{ list ($sz_to_dev_nul, $sz_to_Date) = explode(';',$aux['Received'][0],2);
 $aux["timestamp"] = strtotime($sz_to_Date);
} else
{ $aux["timestamp"] = '';
}

    The Tiki webmail reply feature reports a similar complaint:

    Image
    Copy to clipboard
    Notice: Undefined index:
 delivery-date in .../tiki-webmail.php on line 252
Notice: strtotime():
 Called with empty time parameter in
 .../tiki-webmail.php on line 252

    The refenced code is:

    Image
    Copy to clipboard
    [LINE 251] }
[LINE 252] $output['header']['timestamp'] = strtotime($output['header']['delivery-date']);

    I again used the PHP function print_r(), this time to inspect what the output header array contains. The culprit turned out to be the absence of a 'delivery-date' record. Instead, the message header as parsed from qmail apparently replaces that with a 'received' array.

    Image
    Copy to clipboard
    Array
(
 [header] => Array
  (
   [return-path] => <ac...@ho...>
   [delivered-to] => ac...@ho...
   [received] => Array
    (
     [0] => (qmail # invoked by uid #); 2 Jan 2006 23:56:00 -0000
     [...] =>
     [n] => from node.sourcehost.tld (HELO www.host.tld) (#.#.#.#)
            by smtp.host.tld with SMTP; 2 Jan 2006 23:59:00 -0000
    )

    My fix (yes, it works) is similar, but extracts the last 'received' line (n) into the date value, as such:

    Image
    Copy to clipboard
    if (array_key_exists('delivery-date',$output['header']))
 { $output['header']['timestamp'] = strtotime($output['header']['delivery-date']);
 } elseif (array_key_exists('received',$output['header']))
 { $i_output_header_received = sizeof($output['header']['received']) - 1;
  list ($sz_to_dev_nul, $sz_to_delivery_date)
   = explode(';',$output['header']['received'][$i_output_header_received],2);
  $output['header']['timestamp'] = strtotime($sz_to_delivery_date);
 } else
 { $output['header']['timestamp'] = '';
 }
