How to save log massage when update datable?

t3631867

I want to log who update the table info, so I try to log msg when datatable updating.

I put the log code in Editor.php as below, but it's not work.

private function _update( $id, $values )
    {
        $id = str_replace( $this->_idPrefix, '', $id );

        // Update or insert the rows for the parent table and the left joined
        // tables
        $this->_insert_or_update( $id, $values );

        // And the join tables
        for ( $i=0 ; $i<count($this->_join) ; $i++ ) {
            $this->_join[$i]->update( $this, $id, $values );
        }

        // Was the primary key altered as part of the edit? Unusual, but it is
        // possible
        $pkeyField = $this->_find_field( $this->_pkey, 'name' );
        $getId = $pkeyField && $pkeyField->apply( 'edit', $values ) ?
            $pkeyField->val( 'set', $values ) :
            $id;

        // Full data set for the modified row
        $row = $this->_get( $getId );
        $row = count( $row['data'] ) > 0 ?
            $row['data'][0] :
            null;

        $this->_trigger( 'postEdit', $id, $values, $row );

        // ********** my log message **********
        $f=fopen("mylog_update_product.txt","a+");
        $str="";
                $str.="id     = ".$id."\r\n";
                $str.="values = ".$values[0]."\r\n";
                $str.="================================================"."\r\n";      
                fwrite($f, $str);
                fclose($f);
                // ********** END my log message **********

        return $row;
    }

I would strongly suggest you don't put it into Editor.php - use the postEdit server-side event instead.

See also this blog post on the topic.

The reason not to modify Editor.php is that when you update to future versions, you'll need to patch your copy every time!
