The various fields in the HTML Form will have a name attribute which will then become the key [[What is Bitcoin >https://www.techgogoal.com/2020/04/27/what-is-bitcoin-and-how-to-purchase-bitcoin-online/]] of the associative array in $_POST. You can make use of form processing via a 2-page process, or a single page form process. 

There are pros and cons to each, and for now, we’ll take a look at the 2-page approach. What this means is that your first page will contain the HTML markup for the form. That form will have an action attribute, and the value of that attribute is the second PHP page that will process the data. The easiest way to see how this works is to create it in code.

You can process information [[write for us technology >https://www.scrollsocial.in/write-for-us/]] gathered by an HTML form and use ASP code to make decisions based off this information to create dynamic web pages. ... There are two methods for sending data to an ASP form: POST and GET. These two types of sending information are defined in your HTML form element's method attribute.

Each control has both an initial value and a current value, both of which are character strings. Please consult the definition of each control for information about initial values and possible constraints on values imposed by the control. In general, a control's "initial value" may be specified with the control element's value attribute. However, the initial value of a TEXTAREA element is given by its contents, and the initial value of an OBJECT element in a form is determined by the object implementation (i.e., it lies outside the scope of this specification).

The control's "current value" is first set to the initial value. Thereafter, the control's current value may be modified through user interaction and scripts.
