Warning: array_key_exists() [function.array-key-exists]: The first argument should be either a string or an integer in Z:\\home\\localhost\\www\\add_order.php on line 28
2. If someone send second POST with one of products, its do not edit only add new value .
Example: Before
67_1|68_1
after i chooise second time, one or more it was add (Array_1 and maximum second times
67_1|68_1|Array_1|Array_1

Also I have to question why you want to construct a string such as 67_1|68_2 etc. The correct thing to do is to have those numbers (the id and the quantity) stored as separate values in your database
I agree. For a properly designed application where that type of coding is required it is just about the simplest part of the entire code. If you can’t work out that trivial part then you will never get the rest of the code to work. If that isn’t the most trivial part of the code then most likely the design is wrong and you shouldn’t be trying to do that at all.
In my company shop i have products with many prices (in one product can be 5 others prices, group by weight).
Because i have 2 tables (1 where product info and 2 where price with weight) , i don’t found the option to add unlimited prices in one id product with sums of them.
I upload some pics how it looked
And this is tables
CREATE TABLE IF NOT EXISTS `production` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`added` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
`image` varchar(100) NOT NULL DEFAULT '',
`name` varchar(100) NOT NULL,
`napolnitel` text NOT NULL,
`code_production` varchar(20) NOT NULL,
`catname` int(10) NOT NULL,
`about_product` text NOT NULL,
`info_pack` varchar(100) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
CREATE TABLE IF NOT EXISTS `prices` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`product_id` int(10) NOT NULL,
`product_price` int(10) NOT NULL,
`product_weight` int(10) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM;
CREATE TABLE IF NOT EXISTS `sale` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`ip` varchar(15) NOT NULL DEFAULT '',
`userid` int(11) NOT NULL DEFAULT '0',
`date` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
`id_prod` int(10) DEFAULT NULL,
`prices_id` text NOT NULL,
`hash` text NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
i don’t found the option to add unlimited prices in one id product with sums of them.
Yes you do. Just add a quantity column to the sale table. Boom! Unless there’s some reason you can’t alter the database design? But if that was the case that would be a ridiculous state of affairs that any developer should consider themselves to be reasonably entitled to correct.
only add new value .
