The support for message-strings send by triggers is not implemented.



The common error send by triggers is the -746.

In the sqlerrm is the message for the error returned from a trigger.



This driver does not take this in mind.



Sorry for my bad english...

Nice function to call. Very helpfull if you want to use in combination with an own ErrorHandler. But informix error recognition seems just to work directly after calling a informix function.



/**

 * checks weater error has occured or not

 * @return false if no error, else error message

 */

function db_error_occured()

{

    $err_code = ifx_error();

    if (substr($err_code,0,1) != ' ') {

        return ifx_errormsg();

    }

    else {

        return false;

    }

} //db_error_occured
