     34== HTML Forms in Templates ==
     35
     36Diva does not generate HTML markup for your forms automatically. The `diva.forms` package is only concerned with the form data, not the rendering of individual form elements and how they assembled into the larger form.
     37
     38For the form defined above, a simple template might contain something like this:
     39
     40{{{
     41#!genshi
     42<form action="" method="post">
     43  <p>
     44    <label>Your name: <input type="text" name="username" /></label>
     45    <span py:if="'username' in errors" class="error">${errors.username}</span>
     46  </p><p>
     47    <label>Link URL: <input type="text" name="url" /></label>
     48    <span py:if="'url' in errors" class="error">${errors.url}</span>
     49  </p><p>
     50    <label>Title: <input type="text" name="title" /></label>
     51    <span py:if="'title' in errors" class="error">${errors.title}</span>
     52  </p>
     53  <hr />
     54  <p>
     55    <input type="submit" />
     56  </p>
     57</form>
     58}}}
     59
     60Note that while you don't need to manually take care of filling in the form values, you do have to explicitly add any error messages that need to be displayed after a failed validation.
