We add a radio button to choose when annotations should be deleted and a text entry field to limit the number of annotations allowed on a node (implementation of these enhancements in the module is left as an exercise for you). Rather than managing the processing of our own form, we call system_settings_form() to let the system module add some buttons to the form and manage validation and submission of the form. Figure 2-5 shows what the options form looks like now. The Solution Explorer utility (accessible from the View menu) allows you to view the set of all content files and referenced assemblies that comprise the current project (see Figure 2-10). Figure 2-10. The Solution Explorer utility Notice that the References folder of Solution Explorer displays a list of each assembly you have currently referenced, which will differ based on the type of project you select and the version of the Framework you are compiling against. If system_settings_form() is taking care of saving the form values for us, how can we check whether the value entered in the Annotations per node field is actually a number We just need to add the check to see whether the value is numeric to a validation function (annotate_admin_settings_ validate($form, $form_state)) in sites/all/modules/custom/annotate/annotate.admin.inc and use it to set an error if we find anything wrong. /** * Validate annotation settings submission. */ function annotate_admin_settings_validate($form, &$form_state) { $limit = $form_state['values']['annotate_limit_per_node']; if (!is_numeric($limit)) { form_set_error('annotate_limit_per_node', t('Please enter number.')); } } Now when Drupal processes the form, it will call back to annotate_admin_settings_validate() for validation. If we determine that a bad value has been entered, we set an error against the field where the error occurred, and this is reflected on the screen in a warning message and by highlighting the field containing the error. How did Drupal know to call our function We named it in a special way, using the name of the form definition function (annotate_admin_settings) plus _validate. For a full explanation of how Drupal determines which form validation function to call, see 11. barcode reader for java mobile free download Detect Barcode Scanner - Javascript - Laracasts
