Sending more than 1 patroninformation query

[Stan-librarian]

Hi,

I'm sending 4 times the patroninformation query, as recommended :

$query = $mysip->msgPatronInformation('none');
echo '<b>Requête :</b> ' . $query . '<br />' ;
$result = $mysip->get_message($query) ;
echo '<b>Résultat :</b> ' . $result . '<hr />' ;
$query = $mysip->msgPatronInformation('charged');
echo '<b>Requête :</b> ' . $query . '<br />' ;
$result = $mysip->get_message($query) ;
echo '<b>Résultat :</b> ' . $result . '<hr />' ;
$query = $mysip->msgPatronInformation('hold');
echo '<b>Requête :</b> ' . $query . '<br />' ;
$result = $mysip->get_message($query) ;
echo '<b>Résultat :</b> ' . $result . '<hr />' ;
$query = $mysip->msgPatronInformation('overdue');
echo '<b>Requête :</b> ' . $query . '<br />' ;
$result = $mysip->get_message($query) ;
echo '<b>Résultat :</b> ' . $result . '<hr />' ;

but I get a result only for the first one :

I don't see why...

I'm a librarian, so maybe I'm missing something obvious. If that's so, I'm sorry…

Each one of the queries gets a result if I launch it alone. But when I launch 2 queries in a row, the second one doesn't get a result.

I found the solution : in fact my ILS doesnt send the AY and AZ fields. So the CRC control failed each time.
So I modified the function _check_crc($message) by adding the following at the beginning :
if(substr($message, -6, 2) != 'AZ'){return true;}
and that works!

I imagine I could have added false parameters to the calls
return $this->_returnMessage();

Maybe there should be a configuration option to disable error handling…

However, I still don't understand why a single query works but not many…
