HTML Form

A form is an area that contains form elements.

Form elements allow users to enter content in the form, such as: textarea, drop-down lists, radio-buttons, checkboxes, and so on.

The form is set using the form tag <form>:

<form>
input element
</form>

HTML Form - Input Element

The form tag used in most cases is the input tag (<input>).

The input type is defined by the type attribute (type). The most frequently used input types are as follows:

Text Fields

The text field is set by the <input type="text"> tag. When the user wants to type letters, numbers, etc. in the form, the text field will be used.

<form>First name: <input type="text" name="firstname"><br>Last name: <input type="text" name="lastname"></form>

The browser displays as follows:

Note: The form itself is not visible. At the same time, in most browsers, the default width of the text field is 20 characters.

Password Field

The password field is defined by the tag <input type="password">:

<form>Password: <input type="password" name="pwd"></form>

The browser display effect is as follows:

Note: The characters in the password field will not be displayed in plain text, but replaced by asterisks or dots.

Radio Buttons

The <input type="radio"> tag defines the form radio options

<form><input type="radio" name="sex" value="male">Male<br><input type="radio" name="sex" value="female">Female</form>

The browser display effect is as follows:

Checkboxes

<input type="checkbox"> defines the checkbox. The user needs to select one or more options from a number of given options.

<form><input type="checkbox" name="vehicle" value="Bike">I have a bike<br><input type="checkbox" name="vehicle" value="Car">I have a car</form>

The browser display effect is as follows:

Submit Button

<input type="submit"> defines the submit button.

When the user clicks the confirmation button, the content of the form will be transferred to another file. The action attribute of the form defines the file name of the destination file. The file defined by the action attribute usually processes the received input data. :

<form name="input" action="html_form_action.php" method="get">Username: <input type="text" name="user"><input type="submit" value="Submit"></form>

The browser display effect is as follows:

If you type a few letters in the above text box, and then click the confirm button, the input data will be sent to the "html_form_action.php" page. The page will display the input result.
