set_update_batch how to plus 1

@souicp,

Ok, I see what the challenge is.  Normally it would be just view + 1 but because we are doing a batch update and everything is escaped then that is causing the issue. Have you tried ...

'view' => 'view + 1'   (This might be seen as a string)
or
'view' => 'view'+ 1    (This might work)
or
'view' => view + 1     (This might throw an error)

It should be one of the answers above.

it's bug
i fix it 

PHP Code:

    public function update_batch($table, $set = NULL, $index = NULL, $key = NULL, $escape = NULL, $batch_size = 100)
    {
        // Combine any cached components with the current statements
        $this->_merge_cache();

        if ($index === NULL)
        {
            return ($this->db_debug) ? $this->display_error('db_must_use_index') : FALSE;
        }

        if ($set === NULL)
        {
            if (empty($this->qb_set_ub))
            {
                return ($this->db_debug) ? $this->display_error('db_must_use_set') : FALSE;
            }
        }
        else
        {
            if (empty($set))
            {
                return ($this->db_debug) ? $this->display_error('update_batch() called with no data') : FALSE;
            }

            $this->set_update_batch($set, $index, $key, $escape);
        }

        if (strlen($table) === 0)
        {
            if ( ! isset($this->qb_from[0]))
            {
                return ($this->db_debug) ? $this->display_error('db_must_set_table') : FALSE;
            }

            $table = $this->qb_from[0];
        }

        // Batch this baby
        $affected_rows = 0;
        for ($i = 0, $total = count($this->qb_set_ub); $i < $total; $i += $batch_size)
        {
            if ($this->query($this->_update_batch($this->protect_identifiers($table, TRUE, NULL, FALSE), array_slice($this->qb_set_ub, $i, $batch_size), $index)))
            {
                $affected_rows += $this->affected_rows();
            }

            $this->qb_where = array();
        }

        $this->_reset_write();

        if ( ! is_array($key))
        {
            // @todo error
        }

        is_bool($escape) OR $escape = $this->_protect_identifiers;

        foreach ($key as $k => $v)

                    'value'  => (($escape === FALSE && $keys == $k2) ? $v2 : $this->escape($v2))
                );
            }

            if ($index_set === FALSE)
            {
                return $this->display_error('db_batch_missing_index');
            }

            $this->qb_set_ub[] = $clean;
        }

        return $this;
