HTML Input form* Attributes
This chapter describes the different form* attributes for the HTML <input> element.
The form Attribute
The input form attribute specifies the form the <input> element belongs to.
The value of this attribute must be equal to the id attribute of the <form> element it belongs to.
Example
An input field located outside the HTML form (but still a part of the form):
<form action="/action_page.html" id="form1">
<label for="fname">First name:</label>
<input type="text" id="fname" name="fname"><br><br>
<input type="submit" value="Submit">
</form>
<label for="lname">Last name:</label>
<input type="text" id="lname" name="lname" form="form1">

The formaction Attribute
The input formaction attribute specifies the URL of the file that will process the input when the form is submitted.
Note: This attribute overrides the action attribute of the <form> element.
The formaction attribute works with the following input types: submit and image.
Example
An HTML form with two submit buttons, with different actions:
<form action="/action_page.html">
<label for="fname">First name:</label>
<input type="text" id="fname" name="fname"><br><br>
<label for="lname">Last name:</label>
<input type="text" id="lname" name="lname"><br><br>
<input type="submit" value="Submit">
<input type="submit" formaction="/action_page2.html" value="Submit as Admin">
</form>

The formenctype Attribute
The input formenctype attribute specifies how the form-data should be encoded when submitted (only for forms with method="post").
Note: This attribute overrides the enctype attribute of the <form> element.
The formenctype attribute works with the following input types: submit and image.
Example
A form with two submit buttons. The first sends the form-data with default encoding, the second sends the form-data encoded as "multipart/form-data":
<form action="/action_page_binary.asp" method="post">
<label for="fname">First name:</label>
<input type="text" id="fname" name="fname"><br><br>
<input type="submit" value="Submit">
<input type="submit" formenctype="multipart/form-data"
value="Submit as Multipart/form-data">
</form>

The formmethod Attribute
The input formmethod attribute defines the HTTP method for sending form-data to the action URL.
Note: This attribute overrides the method attribute of the <form> element.
The formmethod attribute works with the following input types: submit and image.
The form-data can be sent as URL variables (method="get") or as an HTTP post transaction (method="post").
Notes on the "get" method:
- This method appends the form-data to the URL in name/value pairs
- This method is useful for form submissions where a user wants to bookmark the result
- There is a limit to how much data you can place in a URL (varies between browsers), therefore, you cannot be sure that all of the form-data will be correctly transferred
- Never use the "get" method to pass sensitive information! (password or other sensitive information will be visible in the browser's address bar)
Notes on the "post" method:
- This method sends the form-data as an HTTP post transaction
- Form submissions with the "post" method cannot be bookmarked
- The "post" method is more robust and secure than "get", and "post" does not have size limitations
Example
A form with two submit buttons. The first sends the form-data with method="get". The second sends the form-data with method="post":
<form action="/action_page.html" method="get">
<label for="fname">First name:</label>
<input type="text" id="fname" name="fname"><br><br>
<label for="lname">Last name:</label>
<input type="text" id="lname" name="lname"><br><br>
<input type="submit" value="Submit using GET">
<input type="submit" formmethod="post" value="Submit using POST">
</form>

The input formtarget attribute specifies a name or a keyword that indicates where to display the response that is received after submitting the form.
Note: This attribute overrides the target attribute of the <form> element.
The formtarget attribute works with the following input types: submit and image.
Example
A form with two submit buttons, with different target windows:
<form action="/action_page.html">
<label for="fname">First name:</label>
<input type="text" id="fname" name="fname"><br><br>
<label for="lname">Last name:</label>
<input type="text" id="lname" name="lname"><br><br>
