Question

Please some one tell me how can I position modules like slider or banner in header or how can we define additional regions for the modules.

Answer 1

Well, I am working on it.

Firstly, you should add a new position in the admin page.
Which means you should change three files and add some lines into each.

For example, if you want to add slideshow into header, you should add a new position in

$this->data['text_header'] = $this->language->get('text_header'); // in admin/controller/slideshow.php

////////////////////////////////////////////////

$_['text_header']         = 'Header'; // in admin/language/slideshow.php

////////////////////////////////////////////////

<?php if ($module['position'] == 'header') { ?> // in admin/view/slideshow.tpl
            <option value="header" selected="selected"><?php echo $text_header; ?></option>
            <?php } else { ?>
            <option value="header"><?php echo $text_header; ?></option>
            <?php } ?>

Then a new position for slideshow has been defined. and you can choose it in the admin page.

After that, you should add those codes in catalog/view/header.tpl

 <?php foreach ($modules as $module) { ?>
    <?php echo $module; ?>
    <?php } ?>

Then, in the catalog/controller/header.php, add some codes like content_top.php does:
$layout_id = 1;

$module_data = array();

$this->load->model('setting/extension');

$extensions = $this->model_setting_extension->getExtensions('module');      

foreach ($extensions as $extension) {
    $modules = $this->config->get($extension['code'] . '_module');

    if ($modules) {
        foreach ($modules as $module) {
            if ($module['layout_id'] == $layout_id && $module['position'] == 'header' && $module['status']) {
                $module_data[] = array(
                    'code'       => $extension['code'],
                    'setting'    => $module,
                    'sort_order' => $module['sort_order']
                );              
            }
        }
    }
}

$sort_order = array(); 

foreach ($module_data as $key => $value) {
    $sort_order[$key] = $value['sort_order'];
}

array_multisort($sort_order, SORT_ASC, $module_data);

$this->data['modules'] = array();

foreach ($module_data as $module) {
    $module = $this->getChild('module/' . $module['code'], $module['setting']);

    if ($module) {
        $this->data['modules'][] = $module;
    }
}


if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/common/header.tpl')) {
    $this->template = $this->config->get('config_template') . '/template/common/header.tpl';
} else {
    $this->template = 'default/template/common/header.tpl';
}

$this->render();

Then all done.

The only problem for this code is the slideshow cannot display as a slideshow but a static picture or pictures.

Wish you could solve it out and reply to me.
