H32: Providing submit buttons


Content that includes form controls.

This technique relates to:


The objective of this technique is to provide a mechanism that allows users to explicitly request changes of context. The intended use of a submit button is to generate an HTTP request that submits data entered in a form, so it is an appropriate control to use for causing a change of context.


Example 1:

This is a basic example of a form with a submit button.

Example Code:

<form action="" method="post"><br /> 
 <p>Enter your e-mail address to subscribe to our mailing list.</p><br /> 
 <label for="address">Enter email address:</label><input type="text" 
 id="address" name="address" /> 
 <input type="submit" value="Subscribe" /><br /> 

Example 2:

The following example uses a server-side script (specified in the action attribute) that redirects the user to the requested page.

Example Code:

 <form action="" method="get"><br /> 
    <p>Navigate the site.</p><br /> 
    <select name="dest"><br /> 
      <option value="/index.html">Home</option/><br /> 
      <option value="/blog/index.html">My blog</option/><br /> 
      <option value="/tutorials/index.html">Tutorials</option/><br /> 
      <option value="/search.html">Search</option/><br /> 
    </select><br /> 
  <input type="submit" value="Go to Page" /><br />

  1. Find all forms in the content

  2. For each form, check that it has a submit button (input type="submit", input type="image", or button type="submit")

Expected Results

If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.

Techniques are Informative

Techniques are informative—that means they are not required. The basis for determining conformance to WCAG 2.0 is the success criteria from the WCAG 2.0 standard—not the techniques. For important information about techniques, please see the Understanding Techniques for WCAG Success Criteria section of Understanding WCAG 2.0.
