Submitting Forms to a Server


Description


Once the user has entered all the data into the form via the input controls there needs to be some method to send the data in the form to the server. To do this we use something called a submit button.

Examples

Submit Input Tag

Use the submit input tag type to display a button that the user can press to send the form to the location specified in the form action attribute. Typically this would be a location to a server side script that would process the data entered into the form input tags and then send a response back to the user.
    <input 
        type="submit" 
        value="Send to Server" />

Image Input Tag

Use the Image input tag to use an image instead of the standard submit button. 

    <form>
        <input type="image" src="../images/arrow-up-over.gif" />
    </form>


Attributes for Submit <Input> Tags
