I faced a problem to create a taxonomy vocabulary term when my custom module was enabled. To save a vocabulary we just need a Taxonomy vocabulary save. But here I had to enable it whenever my module is enabled. So I checked out and found this method to add a new taxanomy vocabulary.

Drupal 7 provides a function called hook_enable. This function performs necessary action once the module is enabled. I have used this functionality to add a new taxonomy vocabluary.

In my case I want to add a new Taxonomy vocabulary called Categories. The following code will explain you the process which I did.



    /**
     * Implements hook_enable().
     */

    function photoshare_enable() {
      $vocabulary = taxonomy_vocabulary_load(variable_get('photoshare_categories_vocabulary', 0));
      if (!$vocabulary) {
        $category = array(
          'name' => t('Categories'),
          'machine_name' => 'photoshare_categories',
          'description' => t('Photoshare categories vocabulary'),
          'hierarchy' => 1,
          'module' => 'photoshare',
        );
        $vocabulary = (object) $category;
        taxonomy_vocabulary_save($vocabulary);
        variable_set('photoshare_categories_vocabulary', $vocabulary->vid);
      }
    }

In the above code I checked whether the vocabulary is existing or not at first. If it is not existing then I added the vocabulary category with the required values as an array. Since the taxonomy_vocabulary_save() function needs its input as an object I converted it as an object and saved it. And I have set the value as well.

You can keep the vocabulary if you want even after the module is disabled in this method. If you dont want the vocabulary then you can use hook_disable and taxonomy_vocabulary_delete to delete it.

How can I fix this? Thanks, Sean webmaster access_time 28 Nov 2020 - 17:37 In reply to Icon doesn't show by Sean (not verified) What do you see when you view the source? Search for stumblethis_button and you should be able to see the code for the image and the URL. Then you should be able to troubleshoot from there.

Most webmasters do not realize this, but a lot of the content on lot of websites can be accessed from multiple URLs. A simple example would be where www.example.com and example.com leads to the same page. This is a fatal mistake in Search Engine Optimization and search engines penalize you for duplicate content. The correct configuration would be where the above two urls will lead you to the same page but example.com will redirect you to www.example.com with a 301 (Moved permanently) status which will not result in search engines penalizing the page. It is very easy to configure 301 redirects using Apache .htaccess file and the process is the same for a Drupal installation also.

I'm trying to make example.com show as www.example.com, and I'm running into difficulties. I'm on Apache 2.0 and using the following lines in my httpd.conf file: RewriteEngine on RewriteCond %{HTTP_HOST} ^xxxxxxxxxx\.com$ [NC] RewriteRule ^(.*)$ http://www.xxxxxxxxxx.com/$1 [L,R=301] When I go to http://xxxxxxxxxx.com, I get http://www.xxxxxxxxxx.com (as expected). However, when I go to http://xxxxxxxxxx.com/node/1 (it's a Drupal site), I get a 404 thrown and the URL changes to xxxxxxxxxx.com/var/www/drupal/node/1. Same thing with www.xxxxxxxxxx.com/node/1. Any suggestions? I want to run without Drupal's .htaccess file (instead incorporating these calls into my httpd.conf file). webmaster access_time 28 Nov 2020 - 17:37 In reply to Rewrite including filesystem path by Anonymous (not verified) I think the problem is with the base path which results in the redirection to /var/www/ part. The best approach I would think is to start with drupal htaccess and then strip out parts and move to httpd SNVC (not verified) access_time 28 Nov 2020 - 17:37 This is definitely a good guide. Thanks for this. wellyson access_time 28 Nov 2020 - 17:37 This is really nice and helpful. Add new comment
