Linking to a form element by adding an anchor

This code snippet shows you how you can modify a preexisting form and insert an anchor, which will allow you to link to a specific form element from your content. This could be useful if you'd like a user to update their profile details or fill out a certain section of a form. In this example, I add an anchor to the user profile form picture fieldset.

<?php
function MYMODULE_form_alter(&$form, $form_state, $form_id) {
  // check for the user profile form
  if ($form_id == 'user_profile_form') {
    // add a new anchor form element
    $form['picture']['anchor'] = array(
      '#value' => '<a name="MYMODULE_picture"></a>',
    );
  }
}
?>

Then in my content, I added a link with an anchor.

<?php
$html .= l('Upload profile picture', 'user/' . $GLOBALS['user']->uid . '/edit',
  array('fragment' => 'MYMODULE_picture')
);
?>
