QUESTION if plugin is active ...

[datiswous]

Hello, I forgot where to find certain info regarding theme building.

What if you want to set certain code in your theme depending if a plugin is active, what code do you use?

[shawn_a]

no function in 3.3.x
but you would do it like this.

PHP Code:

/**
 * check if a plugin is active
 * determine if a plugin is active
 *
 * @since 3.4
 * @param  string $pluginid
 * @return bool   returns true if active
 */
function pluginIsActive($pluginid){
    GLOBAL $live_plugins;
    return isset($live_plugins[$pluginid.'.php']) && ($live_plugins[$pluginid.'.php'] == 'true' || $live_plugins[$pluginid.'.php'] === true);
}

Ok, thanks. Although I don't really understand the code. It is for activating a plugins specific code in a theme, but only if plugin exist. I think I just make a separate template file.

[shawn_a]

well no it just checks if a plugin is active

[Tyblitz]

To use shawn_a's function you should just do like this:

PHP Code:

<?php if (pluginIsActive('i18n_base')) { ?>
  <div>You can only see me if i18n_base plugin is activated</div>
<?php } ?>

Or in a template file: 

PHP Code:

<?php if (pluginIsActive('i18n_base')) { include('mytemplate.php'); } ?>

Thanks, but I want to do a certain thing instead of another (default) thing. So if plugin is active, do this, if not, do something else.

[shawn_a]

The you just add an else{}

[datiswous]

Ok thanks, I see if I can make it work..

Another way to know if a plugin is (or isn't) active is checking for some of the plugin's functions (that is available to the frontend), e.g.

PHP Code:

<?php if (!function_exists('i18n_init')) { ?>
   <p>I18N plugin not activated!</p>
<?php } ?>

[shawn_a]

Yeah like Carlos said, that's probably the best option if you are about to call the functions especially.
