HTML Forms

By using html forms we get input data from the user. For example regstration form, contact us feedback etc.

Html forms are enclosed between form element like below:
<form>
</form>

There are numerous form fields that can be use in forms:

-Text field
-Text area
-Checkbox
-Radio buttons
-Select box
-File field

GET and POST:
Form method can be two types i.e. GET and POST.
When
we use GET then all value submitted from the form will be visible to the URL. But when we use POST then form fields are packed into the body and send to the server.

<form method=”POST” action=”index.html”>
…
</form>
