HTML – Hidden fields

 

Hidden fields will not be shown by the browser. Those are necessary when when we have to deal with forms and databases in MySQL, but it does not limit to that. We will use the hidden fields to send additional information to the database, in addition to the information sent by the user.

HTML Code:

<input type="hidden" />

Demo

This fragment of a code will not show anything because the browser treats it as information that must not be shown.

HTML – Other attributes

We will use the attributes name or id to establish a name for our hidden field.

HTML

<input type="hidden" id="age" name="age" value="25" />

<input type="hidden" id="DOB" name="DOB" value="01/01/70" />

<input type="hidden" id="admin" name="admin" value="1" />

We exemplified above three models of hidden fields that could be of use, especially if you have a web page where the user will have to login in order to have access to certain information. The ‘admin’ field is used to verify someone’s role, 1 being administrator, and 0 non-administrator.

HTML Hidden fields are also used when we have to deal with information that we want to put down in more than one form, not obligating the user to have to insert the information many times.

Two Machine Learning Fields

There are two sides to machine learning:

  • Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
  • Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
