Almirena Posted April 3, 2004 Share Posted April 3, 2004 The following error message appears when I go to the shipping module in admin: Fatal error: Cannot redeclare class zones in /home/sounds/public_html/catalog/includes/modules/shipping/zones.php on line 97 This occurred after I followed the instructions for the Additional Shipping Options for Zone Modules, since I need to be able to send goods from Australia to overseas (various postage rates to various continents for various weights, and various postage rates to various states within Australia for various weights). Can anyone help? What's gone wrong? I'm not familiar with PHP, but willing to experiment - however, since I need to get this up and running asap, I don't have the time to learn in-depth...

Almirena Posted April 3, 2004 Author Share Posted April 3, 2004 This, by the way, is the code in the zones.php file in includes/modules/shipping: <?php/* $Id: zones.php,v 1.20 2003/06/15 19:48:09 thomasamoulton Exp $ osCommerce, Open Source E-Commerce Solutions http://www.oscommerce.com Copyright © 2003 osCommerce Released under the GNU General Public License USAGE By default, the module comes with support for 1 zone. This can be easily changed by editing the line below in the zones constructor that defines $this->num_zones. Next, you will want to activate the module by going to the Admin screen, clicking on Modules, then clicking on Shipping. A list of all shipping modules should appear. Click on the green dot next to the one labeled zones.php. A list of settings will appear to the right. Click on the Edit button. PLEASE NOTE THAT YOU WILL LOSE YOUR CURRENT SHIPPING RATES AND OTHER SETTINGS IF YOU TURN OFF THIS SHIPPING METHOD. Make sure you keep a backup of your shipping settings somewhere at all times. If you want an additional handling charge applied to orders that use this method, set the Handling Fee field. Next, you will need to define which countries are in each zone. Determining this might take some time and effort. You should group a set of countries that has similar shipping charges for the same weight. For instance, when shipping from the US, the countries of Japan, Australia, New Zealand, and Singapore have similar shipping rates. As an example, one of my customers is using this set of zones: 1: USA 2: Canada 3: Austria, Belgium, Great Britain, France, Germany, Greenland, Iceland, Ireland, Italy, Norway, Holland/Netherlands, Denmark, Poland, Spain, Sweden, Switzerland, Finland, Portugal, Israel, Greece 4: Japan, Australia, New Zealand, Singapore 5: Taiwan, China, Hong Kong When you enter these country lists, enter them into the Zone X Countries fields, where "X" is the number of the zone. They should be entered as two character ISO country codes in all capital letters. They should be separated by commas with no spaces or other punctuation. For example: 1: US 2: CA 3: GB,FR,DE,NL,JP 4: JP,AU,NZ,SG 5: TW,CN,HK Now you need to set up the shipping rate tables for each zone. Again, some time and effort will go into setting the appropriate rates. You will define a set of weight ranges and the shipping price for each range. For instance, you might want an order than weighs more than 0 and less than or equal to 3 to cost 5.50 to ship to a certain zone. This would be defined by this: 3:5.5 You should combine a bunch of these rates together in a comma delimited list and enter them into the "Zone X Shipping Table" fields where "X" is the zone number. For example, this might be used for Zone 1: 1:3.5,2:3.95,3:5.2,4:6.45,5:7.7,6:10.4,7:11.85, 8:13.3,9:14.75,10:16.2,11:17.65, 12:19.1,13:20.55,14:22,15:23.45 The above example includes weights over 0 and up to 15. Note that units are not specified in this explanation since they should be specific to your locale. CAVEATS At this time, it does not deal with weights that are above the highest amount defined. This will probably be the next area to be improved with the module. For now, you could have one last very high range with a very high shipping rate to discourage orders of that magnitude. For instance: 999:1000 If you want to be able to ship to any country in the world, you will need to enter every country code into the Country fields. For most shops, you will not want to enter every country. This is often because of too much fraud from certain places. If a country is not listed, then the module will add a $0.00 shipping charge and will indicate that shipping is not available to that destination. PLEASE NOTE THAT THE ORDER CAN STILL BE COMPLETED AND PROCESSED! It appears that the osC shipping system automatically rounds the shipping weight up to the nearest whole unit. This makes it more difficult to design precise shipping tables. If you want to, you can hack the shipping.php file to get rid of the rounding. Lastly, there is a limit of 255 characters on each of the Zone Shipping Tables and Zone Countries. */ class zones { var $code, $title, $description, $enabled, $num_zones; // class constructor function zones() { $this->code = 'zones'; $this->title = MODULE_SHIPPING_ZONES_TEXT_TITLE; $this->description = MODULE_SHIPPING_ZONES_TEXT_DESCRIPTION; $this->sort_order = MODULE_SHIPPING_ZONES_SORT_ORDER; $this->icon = ''; $this->tax_class = MODULE_SHIPPING_ZONES_TAX_CLASS; $this->enabled = ((MODULE_SHIPPING_ZONES_STATUS == 'True') ? true : false); // CUSTOMIZE THIS SETTING FOR THE NUMBER OF ZONES NEEDED $this->num_zones = 3; } // class methods function quote($method = '') { global $order, $cart, $shipping_weight, $shipping_num_boxes; if (MODULE_SHIPPING_ZONES_MODE == 'price') { $order_total = $cart->show_total(); } else { $order_total = $shipping_weight; } $dest_country = $order->delivery['country']['iso_code_2']; $dest_zone = 0; $error = false; for ($i=1; $i<=$this->num_zones; $i++) { $countries_table = constant('MODULE_SHIPPING_ZONES_COUNTRIES_' . $i); $country_zones = split("[,]", $countries_table); if (in_array($dest_country, $country_zones)) { $dest_zone = $i; break; } } if ($dest_zone == 0) { $error = true; } else { $shipping = -1; $zones_cost = constant('MODULE_SHIPPING_ZONES_COST_' . $dest_zone); $zones_table = split("[:,]" , $zones_cost); $size = sizeof($zones_table); for ($i=0; $i<$size; $i+=2) { if ($order_total <= $zones_table[$i]) { $shipping = $zones_table[$i+1]; $shipping_method = constant('MODULE_SHIPPING_ZONES_TITLE_' . $dest_zone); if (MODULE_SHIPPING_ZONES_MODE == 'weight') $shipping_method .= " : " . $shipping_weight .

Guest Posted April 3, 2004 Share Posted April 3, 2004 Line 97 has: class zones { I am not familiar with your mod, but, the above can only be declared once - perhaps you need to uninstall the default zones module to use your mods (re-read the documentation)? It is also possible that your contribution is old and therefore not compatible. Look for the above code in your new files. Matti Quote Link to comment Share on other sites More sharing options...
Almirena Posted April 3, 2004 Author Share Posted April 3, 2004 This might seem like a stupid question, but how do I uninstall? Does that mean "do not have this selected", or does it mean something else? Quote Link to comment Share on other sites More sharing options...
Guest Posted April 3, 2004 Share Posted April 3, 2004 There is a 'remove' button when you select the module in admin - it can also be just turned off, however, I would be wary that there may be a conflict using this method - try it, if it doesn't work then try remove - to reinstall you simply click the 'install' button, so its not a problem. Please read the docs for your new module ;) Matti Quote Link to comment Share on other sites More sharing options...
Almirena Posted April 3, 2004 Author Share Posted April 3, 2004 I had already read the documentation, such as it was, for the new module. I double-checked the shipping module selection in admin, and zone WAS deselected. By clicking onto it and having the options EDIT or REMOVE, then clicking onto REMOVE, nothing further was accomplished. It remains uninstalled, as it was before. I'm at my wit's end.

Almirena Posted April 3, 2004 Author Share Posted April 3, 2004 I think I have solved the problem. I ended up discarding the module and just copying and editing the zones.php files myself. Thanks for the suggestions and help - if anyone else gets into the same situation, they're free to email me for more detailed descriptions of what I did to install several different zone modules, for the following areas: Seven states within Australia New Zealand Countries in postal zones 1, 2, and 3 Countries in postal zone 4 Countries in postal zone 5. My modules are, of course, set up for postal rates from Victoria, Australia, but can easily be edited within admin to suit individual needs.

Guest Posted February 27, 2005 Share Posted February 27, 2005 I had the very same problem - after long frustrating hours I finally discovered that I had uploaded the wrong files into the languages/english/modules/shipping directory. Instead of the language zones.php file, I had uploaded the one which lives in modules/shipping, so the calss was declared twice. Quote Link to comment Share on other sites More sharing options...
designgroop Posted July 1, 2006 Share Posted July 1, 2006 I also got this error when I tried to be clever and keeping an old version of zones.php in the modules folder whilst upgrading to the additional shipping mode zones module. (http://www.oscommerce.com/community/contributions,1752/category,2/search,express) By leaving the old zones.php in the directory (albeit, renamed 'zones-old.php') oscommerce simply read both files in and tried to rerun the various processes. I renamed the file 'zones.php.old' which oscommerce doesn't read and life was sweet again. Complete schoolboy error. I feel so ashamed.

disegnosis Posted July 25, 2006 Share Posted July 25, 2006 i'm having the same problem.. i'd tried with the "Additional Shipping Options for Zone Module" and set up shipping rates as for eg. 100:5,500:8,1000:10 i put in the product a weight of 50 and it shows a wrong weight and price.. can someone help me?? thank's Quote Link to comment Share on other sites More sharing options...

I was having problems because I renamed one of my modules "table pre-jan05.php" and it was causing all kinds of errors with my table.php I was getting cannot redeclare class table issues. Finally after reading this, I just deleted the "table pre-jan05.php" and now it works. Teresa Quote Link to comment Share on other sites More sharing options...
