I want to write a drupal module which will toggle between 2 themes according to the time of the server.
Please say, which hook should I implement.
Should I use
function hook_init(){
global $custom_theme;
$custom_theme = (<condition> ? 'theme1' : 'theme2');
}
?
Thanks.
Yes that should work in your module. I have tested it in one of my own and it works fine.

I'm using the All-In-One Video Player plugin and want to alter its behaviour by listening to events that the player emits and taking actions based on them.
I contacted plugin's support team and got a very good response that I'm sure would mean something to someone who understands WordPress - I'm not one of those people.
The support team suggested using the action hook aiovg_player_footer. It looks like I have to implement that function, but I have no idea where to write that code. Is there a specific file that I need to create / update in order to get implement this function.
My function will need to alter the HTML that the plugin produces. Is this just a case of doing something like
echo '<script>console.log("helo");</script>' ?
You should add the following code in functions.php file located in the root of your theme directory:
function so61638829_aiovg_player_footer()
{
// Do something
}
add_action('aiovg_player_footer', 'so61638829_aiovg_player_footer');
I am very beginner in drupal.
I want to change the theme every day of week for users.
for example in saturday show theme 'garland', on sunday show theme 'seven' and so on.
how can I implement it.
I have searched a lot but I found nothing especial.
thanks.
sounds like you are looking for the themekey module!?
ThemeKey allows you to define simple or sophisticated theme-switching rules which allow automatic selection of a theme depending on current path, taxonomy terms, language, node-type, and many, many other properties.
The easiest way to change your frontend theme is to set it in your sites/default/settings.php:
if(date("w")==0)
$conf['theme_default'] = 'seven';
else if(date("w")==1)
$conf['theme_default'] = 'garland';
...
You can easily achieve it by implementing hook_custom_theme
You can figure out what active theme key is by calling:
global $theme_key
inside your hook implementation. Of course every theme that you want to use should be enabled.
I just started working with Wordpress (v. 3.6.1).
I have OptionTree installed and as it seems it handles the Theme Options page. I want to run my function (in a plugin or wherever else) right after the user saves the changes of this page.
So far I found out that option-tree/includes/ot-settings-api.php generates the form and it sets the form action to options.php (which is a wordpress core file). I was thinking about change the action to my custom php file and handle the save procedure and finally runs my own function. But this solution looks pretty ugly.
I wonder if there's another way to get the job done.
Thanks.
Thanks to #Sheikh Heera link (tutsplus) I could find a solution.
I think this is some kind of hack and I still don't know if it is the best way. Anyway I did this:
Create a file your-theme-settings.php in your theme lib folder.
Let Wordpress knows about your file by adding this code in your theme functions.php:
include_once('lib/your-theme-settings.php');
Add this code to your-theme-settings.php:
function your_theme_register_settings() {
register_setting('option_tree', 'option_tree', 'your_theme_validate_options');
}
function your_theme_validate_options($input) {
// do whatever you have to do with $input.
}
add_action('admin_init', 'your_theme_register_settings');
In step 3, I put 'option_tree' as 1st and 2nd argument of register_settings function, because I noticed that the Option Group and Option Name of OptionTree plugin is option_tree.
I'm not sure if this is the best solution, so I would be glad if you shares your ideas.
I wanted to override page.tpl.php for specific content type.
I have tried these thing, nothing works for me.
page--article.tpl.php
page--node--article.tpl.php
page--node--type--article.tpl.php
page--node-type--article.tpl.php
page--type--article.tpl.php
But when I targetted specific node by number i.e. page--node--8.tpl.php it worked fine.
I think page--article.tpl.php should have worked, but I dont know why its not working.
Please tell me if I am naming it wrong. and how can I debug such things. I have heard I can use Devel module, but know nothing about it. A slight hint in right direction will be appreciated.
Thanks in advance
You have to make sure that your template can handle this ... I got a code snippet that worked for me here:
http://drupal.org/node/1089656#comment-4426790
<?php
function themeName_preprocess_page(&$vars, $hook) {
if (isset($vars['node'])) {
// If the node type is "blog_madness" the template suggestion will be "page--blog-madness.tpl.php".
$vars['theme_hook_suggestions'][] = 'page__'. $vars['node']->type;
}
}
?>
Have you remembered to clear the cache (under Administer > Site configuration > Performance) so that Drupal is 'aware' of your new file & uses this rather than the default.
See here on Clearing cached data
Also, you may need to add a preprocess hook (I haven't used D7 myself, just 5/6 — think this has changed slightly.) This post on Drupal Stack Exchange seems to give more details
I just ran into the same problem.
node--recipe.tpl.php
not
page--recipe.tpl.php
this is, of course, with a content type called 'recipe'.
ALWAYS CLEAR THE CACHE...
Go to /admin/config/development/performance and click the clear cache button. It should be the first thing you do if you've made alterations to the structure of the backend and they're not showing as expected.
Otherwise you almost had it right
page--content-type-name.tpl.php
will allow you to theme the content type template.
I know this is an old question but if others arrive here, the way I override content types in drupal 7 is like this
node--contenttype.tpl
You will need to overwrite the specific node template for the content type if it is anything different than a Basic Page. Please check this out:
http://api.drupal.org/node/19080
Under this page copy/paste the items that are in the node.tpl.php page and overwrite it on how you want. You can access the node specifically by $node
Your template for articles would be:
node--article.tpl.php
Once this is created make sure you clear cache to ensure this works.
So depending on what you are trying to accomplish, there might be some CSS tricks that could help you out.
For instance, to override any CSS rules for a specific node type just remember that your pages for that node type will have a body class of "node-type-[TYPE]" (ie: .node-type-article)
You can then override the CSS as follows:
body.node-type-article #selector {}
Step 1.create a content type for example: my content type is "fullwidthpage"
Step 2. copy page.tpl.php and rename to page--fullwidthpage.tpl in template folder.
Step 3. Add this code to template.php
function <strong>YOUR_THEME_NAME_HERE</strong>_preprocess_page(&$variables) {
if (isset($variables['node']->type)) {
// If the content type's machine name is "my_machine_name" the file
// name will be "page--my-machine-name.tpl.php".
$variables['theme_hook_suggestions'][] = 'page__' . $variables['node']->type;
}
}
Don't forgot to change YOUR_THEME_NAME_HERE
I'm developing a Wordpress site that relies on a plugin to be activated for the site to function properly.
The plugin has a few useful functions that I'm using in the site's template files. When the plugin is active, everything works perfectly. If the plugin is deactivated, the content doesn't load.
Wrapping these functions in if(function_exists(...) obviously fixes that, but I'm wondering if there's a cleaner way of doing that in Wordpress. Is there a function that can be placed in the theme's functions.php file that can check if these functions are available every time I call them, and if not provide a safe fallback without me having to wrap them in the function_exists()?
Thanks.
If you're only using it sparingly (1-2 times), use if( function_exists() ). If you're calling the function several times through in different template files, I'd suggest using something like
In your functions.php
function mytheme_related_posts( $someparams = nil ) {
if( function_exists( 'related_posts' ) ) {
related_posts( $someparams );
} else {
echo 'Please enable related posts plugin';
}
}
Then use mytheme_related_posts() in your template.
I think this is the most clear way. It prevents all problems. I think you can write a function instead which can check if these functions are available every time you call them, but I'm almost sure it can cause you more trouble and it burns more memory then simply using if(function_exist()). Don't forget the else branch and it will work fine.
If you want to check if a plugin is active then you should be using the is_plugin_active() function - you can find the docs at: http://codex.wordpress.org/Function_Reference/is_plugin_active
You can then also use if(function_exists()) as well just to doubly make sure :)
