Making Drupal Messages appearing in modal dialog with Bootstrap 3

This post is another step in the theming Drupal 7 wit Bootstrap 3, you can read my previous article about “Drupal 7 and bootstrap 3 theming the login form“.

Now the purpose here is to change the default Drupal messages display system :

default drupal messages

to this a nice modal message using Bootstrap 3 :

Drupal messages with bootrap 3

Okay let’s start :

1) Fist you need to rewrite the theme_status_messages() in your theme.php file like this :

function [your_theme_name]_status_messages($variables) {
  $display = $variables['display'];
  $output = '';

  $status_heading = array(
    'status' => t('Status message'),
    'error' => t('Error message'),
    'warning' => t('Warning message'),
  );
  foreach (drupal_get_messages($display) as $type => $messages) {
    // ! important : adding html needed for the modal.
    $output = '

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    

<div class="modal-dialog ">
      

<div class="modal-content">
        

<div class="modal-body">
';

    $output .= "

<div class=\"_messages $type\">
\n";
    if (!empty($status_heading[$type])) {
      $output .= '

<h2 class="element-invisible">' . $status_heading[$type] . "</h2>


\n";
    }
    if (count($messages) > 1) {
      $output .= " 

<ul>\n";
      foreach ($messages as $message) {
        $output .= '  

<li>' . $message . "</li>


\n";
      }
      $output .= " </ul>


\n";
    }
    else {
      $output .= $messages[0];
    }
    $output .= "</div>


\n";

    $output .= '</div>


        

<div class="modal-footer">
          <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        </div>


      </div>


<!-- /.modal-content -->
    </div>


<!-- /.modal-dialog -->
    </div>


<!-- /.modal -->';
  }
  return $output;
}

2) Now into your script.js file add :

// modals.
$('#myModal').modal();

3) Flush your theme registry cache and Voilà ! now every time the messages will be displayed within the modal dialog box.

Drupal 7 and bootstrap 3 theming the login form

Bootstrap 3 is out with responsiveness, simplified code, new components etc .. so how to integrate this new features on a Drupal theme ? in this tutorial we’ll try to change the default Drupal login form from this :

startTo this :

final_result

1) First of all we’ll need to create a new theme ( in this tutorial we’ll be using Zen theme to create a subtheme) and download the bootstrap source.

2) Second we’ll need to create a custom module to alter the form and remove some of the uneeded html elements.

Okay no more talk let’s start !

– We begin by including the bootstrap css minified file into the subtheme :

yourtheme.info content :

stylesheets[all][] = bootstrap/css/bootstrap.min.css

Notice no important change appears that’s because we need to add bootstrap classes ..

Now we set what we need for the templates :

// set custom tpl for the login page.
function [your_theme_name]_theme() {

  $items = array();

  $items['user_login'] = array(
    'render element' => 'form',
    'path' => drupal_get_path('theme', '[your_theme_name]') . '/templates',
    'template' => 'user-login',
  );
  return $items;
}

//add class to buttons
function [your_theme_name]_button($variables) {
  $element = $variables['element'];
  $element['#attributes']['type'] = 'submit';
  element_set_attributes($element, array('id', 'name', 'value'));

  $element['#attributes']['class'][] = 'form-' . $element['#button_type'];
  $element['#attributes']['class'][] = 'btn';
  // adding bootstrap classes.
  if($element['#button_type'] == 'submit'){
    $element['#attributes']['class'][] = 'btn-primary';
    $element['#attributes']['class'][] = 'btn-lg';
  }
  if (!empty($element['#attributes']['disabled'])) {
    $element['#attributes']['class'][] = 'form-button-disabled';
  }

  return '<input' . drupal_attributes($element['#attributes']) . ' />';
}

/**** theme form textfields. ***/
function [your_theme_name]_textfield($variables) {

  $element = $variables['element'];
  $output = '';
  // login form adding glyphicon.
  if($element['#name'] == 'name') {
    $output = '<span class="input-group-addon"><span class="glyphicon glyphicon-user"></span></span>';
  }

  // force type.
  $element['#attributes']['type'] = 'text';
  // set placeholder.
  if(isset($variables['element']['#description'])){
    $element['#attributes']['placeholder'] = $variables['element']['#description'];
  }

  element_set_attributes($element, array('id', 'name', 'value', 'size', 'maxlength'));
  // adding bootstrap classes.
  _form_set_class($element, array('form-text', 'form-control', 'input-lg-3'));

  $extra = '';
  if ($element['#autocomplete_path'] && drupal_valid_path($element['#autocomplete_path'])) {
    drupal_add_library('system', 'drupal.autocomplete');
    $element['#attributes']['class'][] = 'form-autocomplete';

    $attributes = array();
    $attributes['type'] = 'hidden';
    $attributes['id'] = $element['#attributes']['id'] . '-autocomplete';
    $attributes['value'] = url($element['#autocomplete_path'], array('absolute' => TRUE));
    $attributes['disabled'] = 'disabled';
    $attributes['class'][] = 'autocomplete';
    $extra = '<input' . drupal_attributes($attributes) . ' />';
  }

  $output .= '<input' . drupal_attributes($element['#attributes']) . ' />';

  return $output . $extra;
}

/*** theme password field ***/
function [your_theme_name]_password($variables) {
  $element = $variables['element'];
  $element['#attributes']['type'] = 'password';
  element_set_attributes($element, array('id', 'name', 'size', 'maxlength'));
  _form_set_class($element, array('form-text', 'form-control'));

  $output = '';
  // login form adding glyphicon.
  if($element['#name'] == 'pass') {
    $output = '<span class="input-group-addon"><span class="glyphicon glyphicon-eye-close"></span></span>';
  }

  return $output . '<input' . drupal_attributes($element['#attributes']) . ' />';
}

/** Theme form element **/
function [your_theme_name]_form_element($variables) {
  $element = &$variables['element'];

  // This function is invoked as theme wrapper, but the rendered form element
  // may not necessarily have been processed by form_builder().
  $element += array(
    '#title_display' => 'before',
  );

  // Add element #id for #type 'item'.
  if (isset($element['#markup']) && !empty($element['#id'])) {
    $attributes['id'] = $element['#id'];
  }
  // Add element's #type and #name as class to aid with JS/CSS selectors.
  $attributes['class'] = array('form-item');
  if (!empty($element['#type'])) {
    $attributes['class'][] = 'form-type-' . strtr($element['#type'], '_', '-');
  }
  if (!empty($element['#name'])) {
    $attributes['class'][] = 'form-item-' . strtr($element['#name'], array(' ' => '-', '_' => '-', '[' => '-', ']' => ''));
  }
  // Add a class for disabled elements to facilitate cross-browser styling.
  if (!empty($element['#attributes']['disabled'])) {
    $attributes['class'][] = 'form-disabled';
  }
  if (isset($element['#parents']) && form_get_error($element)) {
    $attributes['class'][] = 'has-error';
  }

  if($element['#type'] != 'radio'){
    $attributes['class'][] = 'input-group';
  }

  $output = '<div' . drupal_attributes($attributes) . '>
' . "\n";

  // If #title is not set, we don't display any label or required marker.
  if (!isset($element['#title'])) {
    $element['#title_display'] = 'none';
  }
  $prefix = isset($element['#field_prefix']) ? '<span class="field-prefix">' . $element['#field_prefix'] . '</span> ' : '';
  $suffix = isset($element['#field_suffix']) ? ' <span class="field-suffix">' . $element['#field_suffix'] . '</span>' : '';

  switch ($element['#title_display']) {
    case 'before':
    case 'invisible':
      $output .= ' ' . theme('form_element_label', $variables);
      $output .= ' ' . $prefix . $element['#children'] . $suffix . "\n";
      break;

    case 'after':
      $output .= ' ' . $prefix . $element['#children'] . $suffix;
      $output .= ' ' . theme('form_element_label', $variables) . "\n";
      break;

    case 'none':
    case 'attribute':
      // Output no label and no required marker, only the children.
      $output .= ' ' . $prefix . $element['#children'] . $suffix . "\n";
      break;
  }
  // remove description we'll use placeholder.
  if (!empty($element['#description'])) {
    //$output .= '
<div class="description">' . $element['#description'] . "</div>

\n";
  }

  $output .= "</div>

\n";

  return $output;
}

Okay now the user-login-template.tpl.php :


<div class="col-md-5 col-md-offset-3 panel">

<div class="panel-heading">
<h2><?php print t('Login'); ?></h2>
</div>

    
<div class="panel-body">
    <?php print drupal_render_children($form) ?>

    </div>

</div>

at this point and if everything is ok you should see something like this :

intermediaire

We need to remove the label to get a nice version, in the custom module :

/** Hook_form_alter **/
function [your_module]_form_alter(&$form, &$form_state, $form_id) {
    // user login
    if($form_id == 'user_login'){
        $form['name']['#title_display'] = 'invisible';
        $form['pass']['#title_display'] = 'invisible';
    }
}

Ps : you’ll need to rebuild the theme registry to see the changes !

Et voilà ! hope you enjoyed. Please if you have any idea about how to do this in a more simple way feel free to comment.

Drupal 6, Theming Search Box

In this tutorial i will try to explain how to modifiy default search box provided by Drupal module “Search“, this one of many other methods and i think it’s the simplest way.

First of all you’ll need to enable it from admin>build>modules interface then associate it to a region.

Creating theme file

First of all create a file on you theme directory called : ‘search-block-form.tpl.php‘ which is a copy of template file of search box module, the problem whith drupal generated forms are the hidden fields and input file names so we need to pay attention to them :

<?php
// $Id: search-block-form.tpl.php,v 1.1 2007/10/31 18:06:38 dries Exp $
?>
<div class="container-inline">
    <?php
    //Default form call.
    //print $search_form;
    ?>
    <label>
<span>
<!-- input type text with correct name search_block_form -->
  <input name="search_block_form" type="text" class="keywords" id="edit-search-theme-form-l" maxlength="50" value="Search..." />
 </span>
<!-- action name "op" -->
<input name="op" type="image" src="<?= url(path_to_theme() . '/images/search.gif', array('absolute' => true)) ?>" class="button" />
    </label>

    <?php
    //hidden values !important
    print $search["hidden"];
    ?>
</div>

That’s all ! there’s an interesting forum topic where you can find other methods like preprocess functions etc. :
