Dreamweaver error: while executing onLoad in RecordsetFind.htm, the following JavaScript error(s)

Thursday, July 16th, 2009

Are you getting the following errors message when using Dreamweaver CS4? (Note that it may happen to Dreamweaver Professional 8 and CS3 as well).

The following translators were not loaded due to errors:
_________.htm: has configuration information that is invalid.
….

In my case it also generate the following error message when you start and close dreamweaver.

while executing onLoad in RecordsetFind.htm, the following JavaScript error(s) occured:
In file “RecordsetFind”:
findRs is not defined

While executing onLoad in TeamAdminTempDelete.html, the following JavaScript error(s) occured:
In file “TeamAdminTempDelete”:
delTempFile is not defined

It turns out that there is something wrong with your Dreamweaver configuration files. It may be caused by file corrupt, or changes in your system.

To solve this you will have to remove the current configuration folders, so that Dreamweaver will generate new one for you. To do that, close your Dreamweaver and go to the following folder:

C:\Documents and Settings\YOUR_WINDOWS_USERNAME\Application Data\Adobe\Dreamweaver CS4\en_US

Rename the “Configuration” folder in to “Configuration-old”, and then fire up your Dreamweaver.

It should generate the new Configuration folder. Now you might loose your last configuration such as the sidebar width, last used view, etc.

Insert into / add element to array at specific position (PHP)

Wednesday, June 17th, 2009

Usually, we can search and identify PHP function just by looking at it’s name which denotes what a function does. For example array_pop(), array_push(), array_search(), array_reverse(), etc. But how about inserting an element into the middle of an array?

array_splice(array &$input, int $offset [, int $length= 0 [, mixed $replacement]] ) is the function that you are looking for. Format to use this function to add new element at certain position in an array is array_splice($array, $insert_position, 0, $element_to_insert);. See below for an example of how this function behaves.

<?php
$input = array("red", "green", "blue", "yellow");
array_splice($input, 2);
// $input is now array("red", "green")
 
$input = array("red", "green", "blue", "yellow");
array_splice($input, 1, -1);
// $input is now array("red", "yellow")
 
$input = array("red", "green", "blue", "yellow");
array_splice($input, 1, count($input), "orange");
// $input is now array("red", "orange")
 
$input = array("red", "green", "blue", "yellow");
array_splice($input, -1, 1, array("black", "maroon"));
// $input is now array("red", "green", "blue", "black", "maroon")
 
$input = array("red", "green", "blue", "yellow");
array_splice($input, 3, 0, "purple");
// $input is now array("red", "green", "blue", "purple", "yellow");

Magento Layout Error after changing Base URL {{base_url}}

Sunday, June 14th, 2009

When I first login to admin menu on my Magento, I was bothered by this message at the top of my admin interface.

{{base_url}} is not recommended to use in a production environment to declare the Base Unsecure Url / Base Secure Url. It is highly recommended to change this value in your Magento configuration.

Well, most likely you will stumble upon this message on localhost installation. Please do not change this to uncorrect value or else… your Magento site will just break down. If you did it anyway, follow these steps:

  1. Go to your Magento database (you can use phpmyadmin) and open core_config_data table. Then find a row which has path = ‘web/unsecure/base_url’ and change the value back to {{base_url}}.
  2. Finally, to make it works you need to clear out any cache. Go to your magento installation, and open var folder, then delete the session folder (in other word, delete /magento/var/session).

Now, if you still want to update {{base_url}}, read this article http://www.magentocommerce.com/blog/comments/security-update-for-magento-base-url-configuration-value/. Well, in my opinion, Magento is premature product, so it is still fragile. You have to think twice before implement it on your production site.

What’s new in ZenCart 2.0.0

Monday, January 12th, 2009

After a long time waiting, Zencart team will release the new Zen Cart v2.0.0. It was originally planned to be released at the end of 2008 but they will most likely to release the upcoming Zencart 2.0 release early this year. The following will cover what you can expect from new Zencart 2.0.0, which is a summary of what I got from Zencart forum (Comming soon Zencart 2.0.0).

Speed
An emphasis has been placed on improving performance by various methods, especially reducing the number of database queries required for processing pages.

Code
For the programmers, you’ll be happy to know that the code has been largely converted to a much more efficient OOP structure, which will ultimately end up making future growth much simpler.

Templating
Templating is much simpler, in that the complicated PHP blocks that used to make them so hard to read or follow or customize have been removed. Stylesheets are leaner. And there are some very easy-to-use admin-side layout controls to make setting your desired layouts *much* simpler.

Overrides
The same override system exists for templates and language files, meaning that those already familiar with that part of the directory structure will find it easy to continue using.

Languages
UTF-8 support is now native, and the more complicated language files have been simplified and split off into their own for easier management.

Written for PHP 5
Zen Cart 2.0 takes advantage of features specific to PHP 5.2 and MySQL 4.1, thus, those are the new minimum requirements for your hosting service to provide in order to run it. CURL is also highly recommended.

And Many More…

It’s time to move our system from Zencart 1.3.8 to Zencart 2.0.0 and for those who are planning to customize Zencart system, I would just recommend you to postpone it. So that you can implement the changes in Zencart 2.0.0 directly to reduce overhead cost.

Add custom Admin configuration field setting for Zencart

Wednesday, December 3rd, 2008

Have you created your own module for Zencart? And you would like to add configuration setting for your module, so that your client can configure your module via Admin area? Here is how to do that…

What I do usually is adding new group (with your module name) under Configuration in zencart administrator, then add fields under that group to be setup. Just like if you go to Configuration > My Store, you will find many settings there. All of this fields are declared inside your database, specifically inside zen_configuration_group and zen_configuration table (NB: zen_ is used as table prefix).

So let’s insert new row to your zen_configuration_group to create new group under “Configuration” menu. The following SQL script will add “My New Module” group under “Configuration” menu and position it in the last order. Use this script as template.

1
2
3
4
5
INSERT INTO configuration_group
(configuration_group_id, configuration_group_title, configuration_group_description, sort_order, visible)
VALUES (NULL, 'My New Module', 'My New Module Description....', '1', '1');
 
UPDATE configuration_group SET sort_order = last_insert_id() WHERE configuration_group_id = last_insert_id();

Secondly, to add config items under your new “Configuration > My New Module” use the following SQL

1
2
3
4
5
6
7
8
9
SET @last_id=0;
SELECT (@last_id:=configuration_group_id) AS last_id 
FROM configuration_group
WHERE configuration_group_title= 'My New Module';
 
INSERT INTO configuration 
(configuration_id, configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, date_added)
VALUES 
('', 'Small Image Height', 'IMAGE_VIEWER_SMALL_IMAGE_HEIGHT','75','Description of Small Image Height Setting. Default 75.', @last_id, 1, now());

Note that to run this SQL smoothly without bothering with your zencart database table prefix, execute this script from zencart admin area Tools > Install SQL Patches.

Once you executed those SQL, you will find My New Module category under Configuration menu and Small Image Height setting inside that category. You can then access the value of this configuration from your module straight away by using configuration_key which you have set in your SQL (i.e. echo IMAGE_VIEWER_SMALL_IMAGE_HEIGHT). Please leave comment if you find any difficulties or feel grateful with this blog. Cheers.
