HTML POST vs GET & Form Validations
The method attribute in Html forms can either take GET or POST value. We will what each method does and when to use it
What is GET?
The GET method is when data is not protected when transmitted. This means the data which is sent is less protected and easily intercepted
The GET method is used mainly for search queries where the entered data is not sensitive or private
The GET method sends the data of form or a search query through the url. So it is visible and less protected
The GET method can only transmit a maximum of 2,048 characters
This is the default method used in Html forms
What is POST?
POST method makes sures that data is not visible or send through the url. This makes it more secure and reliable
The POST method is mainly used to transmit very sensitive data such as credit card details and passwords
POST method allows encryption of data making it more secure and less likely to be hacked
The POST method allows unlimited characters to be transmitted
It is better to always use POST for any kind of form except for search bars
POST vs GET
The POST method can tranmit more data than GET
The GET method is less secure than POST
POST allows encryption - enctype
GET method executes much faster and through urls

This topic is mainly focused on Javascripting and PHP but, even HTML has some attributes which can be used to validate the data entered
min - used for number input types where it defines the lowest possible number which can be entered
min - used for number input types where it defines the highest possible number which can be entered
autofocus - makes sure the input field is automatically highlighted when the page is loaded
placeholder - used to hint the user what kind of data to be entered
