OsCommerce w/ MySQL Store Transfer

Today I was asked to transfer an OSCommerce store with MySQL for a client.

First of all, we need to login to the old server and archive all the data. So navigate to home directory and issue the following command


tar -cvf old.tar ./


Now FTP this directory to the new server and untar it.


tar -xvf old.tar


Now we need to dump MySQL databases. Login to old server and issue:


mysqldump -uusername -ppassword -a --databases database1 database2 database3 | ssh user@newhost.com "mysql -uusername_new -h hostname_new.com -ppassword"



The hostname is needed in the above command if you cannot connect using localhost.

Q: Does anyone know how I can dump a database that has a "." in its name? I tried escaping it with a backslash but I still get errors while selecting it.

At this point, we need to be able to preview the new domain name under a URL. Since the project for which I am doing this for surprisingly doesn't has a preview URL, I must wait for the client's hosting company to setup a preview URL so I can continue with the transfer.

Part 2

Ok, so I just got the notification that a dedicated IP has been assigned to the site. I can therefore continue with the migration.

I first transferred the files to the public folder where they can be accessible.
I also changed my hosts file on my laptop to take advantage of temporary routing (so I can get the store to work without having to change DNS).

After the files were transferred, everything looked fine at first glance but when I tried the advanced search, I got the following error.


1054 - Unknown column 'p.products_id' in 'on clause'

select count(distinct p.products_id) as total from products p left join manufacturers m using(manufacturers_id), products_description pd left join specials s on p.products_id = s.products_id, categories c, products_to_categories p2c where p.products_status = '1' and p.products_id = pd.products_id and pd.language_id = '1' and p.products_id = p2c.products_id and p2c.categories_id = c.categories_id and ((pd.products_name like '%disney%' or p.products_model like '%disney%' or m.manufacturers_name like '%disney%') )



Oops, what's going on here? Checking the version revealed that the client had MySQL 5 on new server and MySQL 4 on the old one. I had luckily asked about this issue previously and had received some good comments on how to fix the issue. On top of that I found the change log of OSCommerce that documents the changes that need to be made to make OScommerce compatible for MySQL 5.

So I opened up the advanced_search_result.php and modified as follows:


/*Start for MySQL5 */
$from_str = "from " . TABLE_PRODUCTS . " p left join " . TABLE_MANUFACTURERS . " m using(manufacturers_id) left join " . TABLE_SPECIALS . " s on p.products_id = s.products_id";



if ( (DISPLAY_PRICE_WITH_TAX == 'true') && (tep_not_null($pfrom) || tep_not_null($pto)) ) {

if (!tep_session_is_registered('customer_country_id')) {

$customer_country_id = STORE_COUNTRY;

$customer_zone_id = STORE_ZONE;

}

$from_str .= " left join " . TABLE_TAX_RATES . " tr on p.products_tax_class_id = tr.tax_class_id left join " . TABLE_ZONES_TO_GEO_ZONES . " gz on tr.tax_zone_id = gz.geo_zone_id and (gz.zone_country_id is null or gz.zone_country_id = '0' or gz.zone_country_id = '" . (int)$customer_country_id . "') and (gz.zone_id is null or gz.zone_id = '0' or gz.zone_id = '" . (int)$customer_zone_id . "')";


}



$from_str .= ", " . TABLE_PRODUCTS_DESCRIPTION . " pd, " . TABLE_CATEGORIES . " c, " . TABLE_PRODUCTS_TO_CATEGORIES . " p2c";



$where_str = " where p.products_status = '1' and p.products_id = pd.products_id and pd.language_id = '" . (int)$languages_id . "' and p.products_id = p2c.products_id and p2c.categories_id = c.categories_id ";
/* END change for MySQL 5*/



IN index.php I changed

$listing_sql = "select " . $select_column_list .

mysqldump has quite a few nice options.
Like:
-Q, --quote-names
Quote table and column names with backticks (`).

This is actually on by default now.

Arjen,

Thank you for the tip.

For OsCommerce, just copy the index.php and advanced_search_results.php from any other OsCommerce installation in the server ( or you can just fresh install a OsCommerce to any test folder and then copy the two said files to your OsCommerce folder)

HI,

I am getting this error:

1054 - Unknown column 'p.products_id' in 'on clause'

select p.products_image, pd.products_name, p.products_id, p.manufacturers_id, p.products_price, p.products_tax_class_id, IF(s.status, s.specials_new_products_price, NULL) as specials_new_products_price, IF(s.status, s.specials_new_products_price, p.products_price) as final_price from products_description pd, products p left join manufacturers m on p.manufacturers_id = m.manufacturers_id, products_to_categories p2c left join specials s on p.products_id = s.products_id where p.products_status = '1' and p.products_id = p2c.products_id and pd.products_id = p2c.products_id and pd.language_id = '1' and p2c.categories_id = '62' order by pd.products_name

can you tell me what code should i replace this with to make it work?

Thnx

Re:

"1054 - Unknown column 'p.products_id' in 'on clause'"

Does the products_id field exists in the products table?
