Portal Properties Hook in Liferay

Today we will discuss about Portal Properties hook.When we Create Account in liferay we have to provide the value of captcha today we disable the captcha field using Portal Properties hook.

We have portal.properties file inside portal-impl (\ROOT\WEB-INF\lib) which contain some properties.Here some properties have multiple values and some have only one value like true/false.

All properties of portal.properties can not be override,we can override only those properties that is mentioned in dtd file you can find dtd file in definition folder of source code .
ex:- liferay-hook_6_1_0.dtd.

So Lets start this step by step:-

Step 1:-DownLoad dtd file
First download liferay-hook_6_2_0.dtd file and check property related to captcha .Verify that any property is related to our requirement is available or not. Ex- we found properties like:-
captcha.check.portal.create_account 






Step 2:-Create Liferay hook project
File-->New-->Liferay Plugin Project-->Provide name-->Select hook in plugin type-->Finish

Step 3:-Create  hook inside project
Right click on project-->New-->Liferay hook Configuration-->tick portal.properties-->Next

Then in specify properties to override click on Add button

Then Add Property override box is open click on select and select 
captcha.check.portal.create_account and provide value to false

Click ok and finish.

a)portal.properties(inside src)

captcha.check.portal.create_account=false

b)liferay-hook.xml(inside web-inf)

</hook>
