2. What are HTML Forms Basics?

2.1. Why Use HTML Forms?

  • As we are living in a modern world and technologies are advancing day by day.
  • Therefore, we have to interact with people globally over the internet and receive multiple sorts of data.
  • Moreover, due to excessive usage of the internet and most businesses shifting online, companies want to acquire consumers' data abundantly.
  • Firms receive statistics in various ways as per their need like sign-ups, sing-in, feedback, etc.
  • Further, the data may include name, email address, phone number, address, gender, etc.
  • In order to collect these types of data, HTML5 markup allows us miscellaneous form elements to get the appropriate kind of input from the users.
  • As the use of forms is so much involved in our daily life, we have to keep some basics and rules in our minds for their correct usage to get the relevant data keeping on a safer side.
  • The basics of HTML5 forms are helpful for the developers to develop a form with appropriate standards.

2.2. Basics of HTML Forms Controls

Since we create an HTML form in order to collect data from the users. The HTML form collects the data by employing certain input elements known as form controls.

  • Also, these are named form controls with HTML name attribute and further, there are variety of input control elements as per the data type.
  • Moreover, the scope of the name attribute is limited to that particular HTML form control element.
  • Additionally, each control has an "initial" value and a "current" value.
  • Generally, the "initial" control value of an input element is set by using the "value" attribute.
  • However, the "initial" value of the <textarea> element is declared by its contents and the "initial" value of the <object> tag is given by the object implementation.
  • Initially, the "current" value of the HTML form controls is equal to the "initial" control value which is later changed by users or other scripts.
  • Furthermore, the "initial" value of a control does not change and it sets back to its original value upon resetting the form.

4. HTML Forms Associated Tags or Elements

Since we can collect or submit the above types of input data using forms, for this purpose, the HTML language provides us with different HTML5 control tags or elements. All of these HTML form control elements are listed in the following table and we often add the singleton <input> tags in our forms to get the job done.

Sr Control Tag Description
1 <form> The <form> tag is the parent of all the elements in HTML5 forms.
2 <button> This <button> tag is helpful to create buttons in an HTML form.
3 <caption> The <caption> element is useful for defining a caption of a particular HTML5 form just like images.
4 <datalist> This <datalist> element, unlike the <optgroup> form control, help us to to create a list of available choices by using the HTML <option> tag and it is connected with a text input field.
5 <fieldset> The <fieldset> tag visually groups an HTML5 form by enclosing all of its input control elements.
6 <input> The <input> control element is the most used tag in HTML forms to request multiple sorts of data like text, number, time, file, etc.
7 <isindex> This <isindex> deprecated element was used to create a text field in a form to query the document.
8 <keygen> The <keygen> deprecated tag was used to assist in the generation of a key and submit it as a part of the HTML5 form.
9 <label> This <label> tag creates a label for other control inputs of an HTML form.
10 <legend> The HTML5 <legend> element defines a caption for the fieldset of a form.
11 <object> This <object> element embeds an image in an HTML form.
12 <optgroup> The <optgroup> HTML tag works with the <option> element to create a drop-down list in an HTML5 form.
13 <option> This <option> tag creates an option for the <select> or <optgroup> elements to define a list.
14 <output> Th3 <output> tag is usable to display some output based on some <input> form controls.
15 <select> This <select> HTML5 element creates a drop-down list using the <option> tag in a from.
16 <textarea> The <textarea> element is employed in an HTML form to create a text input field and its width and height can be set manually.


In addition to the above-mentioned form controls, we can also utilize other general HTML tags like links, paragraphs, headings, etc.

5. Attributes of HTML5 Forms

Besides the input control elements in HTML forms, there are various attributes that are incorporated to get even more functionality. Moreover, there are certain global attributes that can be applied to all HTML elements including form control tags.

6. HTML5 Forms Validation And Submission

6.1. HTML Form Validation

While getting the user input with an HTML form, it is very important to check that all the input fields by the user are populated with correct data types. We do not want to collect names for password fields, images for birthday fields, and so on. These types of checks ensure the correct format of data and are called form validation. Basically, there are two methods of form validations.

  1. Client-side Form Validation: This type of validation is incorporated within the HTML form and is an initial check to validate the input controls before submission.
  2. Server-side Form Validation: This type of validation is done after a user submits the data and is more secure. In this validation type, we can perform various functions on the input data, store it, sort it, store it in a particular list, etc.

6.2. HTML Form Submission

After validating the input data at client-side, a form is submitted using the form <input> control with type="submit" attribute. For submitting the form data, we also incorporate an HTML attribute method that specifies the HTTP method used to send the form data. There are two values for this attribute.

  1. GET: If this method is used, the form data is appended to the URL defined by the action attribute to send the form controls data to the processing agents or database.
  2. POST: If this method is utilized, the input data is included in the body of the form and sent to the database or other localtion as defined by the URL with the HTML action attribute.


The GET method restricts the data to only ASCII characters only, whereas, the POST method allows all the character-set defined by the ISO10646 standard.
