jqgrid update two tables from one grid

Question

I have two tables in one grid displayed (via LEFT JOIN ) and I wonder is there a way to implement an inline edit functionality for both table from the same grid?

Ie: when the main grid table updated:

onSuccess { table_name, {column1=value1,column2=value2,..}}

not necessarily above scenario - I'm seeking here for ideas and logic to it...

I know there is setAfterCrudAction function in jqGridPHP suit, but from the whole suit I only need this functionality... so I'm seeking to try to implement it myself with some help from you

any ideas appreciated, thanks

Answer 1

Example shows how to update fields when join is used (check 'PHP Grid' tab, btw jqgrid-php is free):

<?php

class jqOperBasic extends jqGrid
{
    protected function init()
    {
        $this->table = 'tbl_order_item';

        $this->query = "
            SELECT {fields}
            FROM tbl_order_item i
                JOIN tbl_books b ON (i.book_id=b.id)
            WHERE {where}
        ";

        #Set columns
        $this->cols = array(

            'item_id' => array('label' => 'ID',
                'db' => 'i.id',
                'width' => 10,
                'align' => 'center',
                'formatter' => 'integer',
            ),

            'order_id' => array('label' => 'Order id',
                'db' => 'i.order_id',
                'width' => 15,
                'align' => 'center',
                'formatter' => 'integer',
            ),

            'name' => array('label' => 'Book name',
                'db' => 'b.name',
                'width' => 30,
                'editable' => true,
                'editrules' => array('required' => true),
            ),

            'price' => array('label' => 'Price',
                'db' => 'i.price',
                'width' => 15,
                'align' => 'center',
                'formatter' => 'integer',
                'editable' => true,
                'editrules' => array('required' => true,
                    'integer' => true,
                    'minValue' => 1,
                    'maxValue' => 3000
                ),
            ),
        );

        #Set nav
        $this->nav = array('edit' => true, 'edittext' => 'Edit');
    }

    #Save columns to different tables
    protected function opEdit($id, $upd)
    {
        #Server-side validation
        if(strlen($upd['name']) < 5)
        {
            #Just throw the exception anywhere inside the oper functions to stop execution and display error
            throw new jqGrid_Exception('The book name is too short!');
        }

        #Get editing row
        $result = $this->DB->query('SELECT * FROM tbl_order_item WHERE id=' . intval($id));
        $row = $this->DB->fetch($result);

        #Save book name to books table
        $this->DB->update('tbl_books', array('name' => $upd['name']), array('id' => $row['book_id']));
        unset($upd['name']);

        #Save other vars to items table
        $this->DB->update('tbl_order_item', $upd, array('id' => $id));
    }
}
