bunch of code in one place

Fatal error: Cannot re-assign $this in /home/…../admin/includes/classes/upload.php on line 31

Posted by admin in osCommerce, tips

I logged in to osCommerce shop administration and I got this error:

Fatal error: Cannot re-assign $this in /home/…../admin/includes/classes/upload.php on line 31

Few days ago the shop was transferet to a server with PHP5 installed. So the problem needs to be fiksed and here is how:

Open file /admin/includes/classes/upload.php and obviously go to line 31 or find:

$this = null;

And replace it with:

unset($this);

The administration should work perfectly now.

Joomla: DB function failed with error number 1054

Posted by admin in joomla, tips

A joomla website was transfered from old server using MySql 4.1.x to new server using MySql 5.

When I tried to edit the website content in joomla administration I got next error:

DB function failed with error number 1054
Unknown column ‘c.access’ in ‘on clause’ SQL=SELECT c.*, g.name AS groupname, cc.name, u.name AS editor, f.content_id AS frontpage, s.title AS section_name, v.name AS author FROM jos_content AS c, jos_categories AS cc, jos_sections AS s LEFT JOIN jos_groups AS g ON g.id = c.access LEFT JOIN jos_users AS u ON u.id = c.checked_out LEFT JOIN jos_users AS v ON v.id = c.created_by LEFT JOIN jos_content_frontpage AS f ON f.content_id = c.id WHERE c.state >= 0 AND c.catid = cc.id AND cc.section = s.id AND s.scope = ‘content’ ORDER BY s.title, c.catid, cc.ordering, cc.title, c.ordering LIMIT 0, 10

The problem can be solved by editing this file: /administrator/components/com_content/admin.content.php

Find:

$query = “SELECT c.*, g.name AS groupname, cc.name, u.name AS editor, f.content_id AS frontpage, s.title AS section_name, v.name AS author”
. “\n FROM #__content AS c, #__categories AS cc, #__sections AS s”
. “\n LEFT JOIN #__groups AS g ON g.id = c.access”
. “\n LEFT JOIN #__users AS u ON u.id = c.checked_out”
. “\n LEFT JOIN #__users AS v ON v.id = c.created_by”
. “\n LEFT JOIN #__content_frontpage AS f ON f.content_id = c.id”
. ( count( $where ) ? “\nWHERE ” . implode( ‘ AND ‘, $where ) : ” )
. $order
. “\n LIMIT $pageNav->limitstart,$pageNav->limit”
;

And replace it with:

$query = “SELECT c.*, g.name AS groupname, cc.name, u.name AS editor, f.content_id AS frontpage, s.title AS section_name, v.name AS author”
. “\n FROM #__content AS c” //, #__categories AS cc, #__sections AS s”
. “\n LEFT JOIN #__groups AS g ON g.id = c.access”
. “\n LEFT JOIN #__users AS u ON u.id = c.checked_out”
. “\n LEFT JOIN #__users AS v ON v.id = c.created_by”
. “\n LEFT JOIN #__content_frontpage AS f ON f.content_id = c.id”
. “\n LEFT OUTER JOIN #__categories AS cc ON c.catid=cc.id”
. “\n LEFT OUTER JOIN #__sections AS s ON cc.section=s.id”
. ( count( $where ) ? “\nWHERE ” . implode( ‘ AND ‘, $where ) : ” )
. $order
. “\n LIMIT $pageNav->limitstart,$pageNav->limit”
;

osCommerce: Add category and product name in title tag

Posted by admin in osCommerce, tips

I’m doing search engine optimization for a shop powered by osCommerce. Title tags are very important for that, so I wanted it to look like this: Shop name :: Category name :: Product name.

If you are using STS (Simple Template System) use:

1. Open file /catalog/includes/modules/sts_inc/general.php
2. Find line:
   

   $sts->template[’headertags’]= “<title>” . TITLE .”</title>”;

   and replace it with:

   // BOF add category and product name in title tag
   $product_title_query = tep_db_query(”select pd.products_name, pd.products_description from ” . TABLE_PRODUCTS . ” p, ” . TABLE_PRODUCTS_DESCRIPTION . ” pd where p.products_id = ‘” . (int)$HTTP_GET_VARS[’products_id’] . “‘ and pd.products_id = p.products_id and pd.language_id = ‘” . (int)$languages_id . “‘”);
   $product_title = tep_db_fetch_array($product_title_query); // get product name

   $category_query = tep_db_query(”select cd.categories_name, c.categories_image from ” . TABLE_CATEGORIES . ” c, ” . TABLE_CATEGORIES_DESCRIPTION . ” cd where c.categories_id = ‘” . (int)$current_category_id . “‘ and cd.categories_id = ‘” . (int)$current_category_id . “‘ and cd.language_id = ‘” . (int)$languages_id . “‘”);
   $category = tep_db_fetch_array($category_query); // get category name

   $sts->template[’headertags’]= “<title>” . TITLE . ” :: ” . $category[’categories_name’] . ” :: ” . $product_title[’products_name’] . “</title>”;
   // EOF add category and product name in title tag

3. Upload the file and you’re done!

If you are using basic osCommerce use:

1. Open file /catalog/index.php
2. Find line:
   

   <title><?php echo TITLE; ?></title>

   and replace it with:

   <?php // BOF add category and product name in title tag
   $product_title_query = tep_db_query(”select pd.products_name, pd.products_description from ” . TABLE_PRODUCTS . ” p, ” . TABLE_PRODUCTS_DESCRIPTION . ” pd where p.products_id = ‘” . (int)$HTTP_GET_VARS[’products_id’] . “‘ and pd.products_id = p.products_id and pd.language_id = ‘” . (int)$languages_id . “‘”);
   $product_title = tep_db_fetch_array($product_title_query); // get product name

   $category_query = tep_db_query(”select cd.categories_name, c.categories_image from ” . TABLE_CATEGORIES . ” c, ” . TABLE_CATEGORIES_DESCRIPTION . ” cd where c.categories_id = ‘” . (int)$current_category_id . “‘ and cd.categories_id = ‘” . (int)$current_category_id . “‘ and cd.language_id = ‘” . (int)$languages_id . “‘”);
   $category = tep_db_fetch_array($category_query); // get category name
   ?>
   <title><?php echo TITLE . ” :: ” . $category[’categories_name’] . ” :: ” . $product_title[’products_name’]; ?></title>

3. Do the same for file /catalog/product_info.php
4. Upload files and that’s it!

Note: Page title (TITLE) is found in your language file (for example: /catalog/includes/language/english.php)

How to find your absolute server path

Posted by admin in tips

1. Create new php file (let’s say you name it abspath.php).
2. Insert this code in that file:
   

   <?php
   $abspath = getcwd();
   echo $abspath;
   ?>

3. Upload the file with FTP to the root directory of your site.
4. Run http://www.your-domain.com/abspath.php in browser and you will get your absolute server path.

osCommerce - Your Shopping Cart is empty!

Posted by admin in osCommerce, tips

I installed Ultimate SEO contribution to my osCommerce shop. Then i noticed, if I click on ‘Buy now’ button from product listing page, I get ‘Your Shopping Cart is empty!’ page. That’s not good for business right, so I had to fix the problem. So to do that, open /includes/modelus/product_listing.php and find code:

$lc_text = ‘<a href=”‘ . tep_href_link(basename($PHP_SELF), tep_get_all_get_params(array(’action’)) . ‘action=buy_now&products_id=’ . $listing[’products_id’]) . ‘”>’ . tep_image_button(’button_buy_now.gif’, IMAGE_BUTTON_BUY_NOW) . ‘</a> ‘;

and repleace it with:

$lc_text = ‘<a href=”‘ . tep_href_link(basename($PHP_SELF), ‘action=buy_now&products_id=’ . $listing[’products_id’]) . ‘”>’ . tep_image_button(’button_buy_now.gif’) . ‘</a> ‘;
