I was building a custom module in Magento. I had created a system.xml file for storing configuration data from admin. From the below system.xml file, you can see that I have created a section named ‘My Module Name‘ which can be accessed from Admin –> System –> Configuration.
In the file below, I have just displayed the section and groups name. I have omitted others fields with dots, as they are not necessary here.

Scenario:
While editing product programatically from frontend. I was trying to change the status of the product with the following code:
Mage::getModel(‘catalog/product’)->load($product->getId())->setStatus(2)->save();

I’m human, Google !

I was googling something and google suddenly said sorry to me. It says my computer is sending automated queries. I was just googling “magento programmer developer nepal” by changing the word position at each time. I just googled this way for at most 5 times.
Google help says the following thing about this issue:

Problem:
I had a new installation of magento. But I was unable to login as an administrator. I went to the admin login page, entered correct username and password but was redirected to the same login page. I could not enter the dashboard page. Error message is displayed when I enter wrong username or password. But nothing is displayed and I am redirected to the same login page when I insert correct username and password.
Solution:

Scenario:
I am installing a fresh magento 1.3.2.1 in my Windows XP computer. I have Xampp installed. While installing magento, I had a problem at the configuration step where I had to fill database host, username, password etc. When I click continue after filling the required fields, the installation process doesn’t move forward. I am redirected to the same page.
Solution:

I was installing Magento 1.3.2.1 in my Windows XP computer. I am using Xampp. I encountered the following errors during the installation.
PHP Extension “curl” must be loaded
PHP Extension “mcrypt” must be loaded
PHP Extension “pdo_mysql” must be loaded

Error:
A potentially dangerous Request.Form value was detected from the client
Scenario:
When you put html tags in your form fields (textbox,textarea) like

Error description:
Cannot insert the value NULL into column ‘SourceId’, table ‘Advisory.dbo.AdvDocSource’; column does not allow nulls. INSERT fails.
The statement has been terminated. The ‘CompanyAdd’ procedure attempted to return a status of NULL, which is not allowed. A status of 0 will be returned instead.
——————————-

This error occurs because the ‘SourceId’ column in my table is primary key and it is set to not null. i.e. it doesn’t allow null entries. And I have not made it auto increment.

This error might occur if you have selected your selection list (dropdownlist) multiple times. You can add multiple=”true” e.g.
in your selection list so as to enable multiple item select.

If you don’t want your selection list to be multiple select enabled then you have to check whether you have selected the selection list multiple times either in your design (aspx file) or in code (aspx.cs file).

Problem

When you start your Windows Operating System, a popup appears related to updatemgr.exe stating that “The NTDVM CPU has encountered an illegal instruction”. This should be closed or ignored. I mean to say that there are two options with this error at a glance. Either you can close it or you can ignore it.
After you close it or ignore it, nothing happens. It’s all fine with your computer and your system. But the main problem is that it appears all the time when you start your computer. And nobody …
