Wordpress Activate

<font color="#ffff00">Description

Try to activate the plug-in in a "sandbox" and redirect if successful. An already active plug-in will not try to be reactivated. But the way it works is to set the redirect to the bug before trying to mount the plug-in for it. In case the plug-in failed, the diversion will not be overridden with the successful one.

In addition, the option will not be refreshed and the checkmark will not be invoked if a plug-in failure occurs. Please note that the following source does not in any way avoid mistakes within the files. Do not use the source at another location to duplicate the "sandbox" that the redirector uses to work.

It will be tracked when it finds bugs or outputs text to make sure successful redirect updates the redirect. cursor (WP_Error|null) indicates incorrect data or'NULL' indicates successful data. Problems with the plug-in queue are created when the plug-in is added or changed after all the plug-ins have been initialized.

You can fix this by refreshing the page, send activate_plugin() as a seperate ask for a JAX file or update the page history manual. For example ; $cache_plugins = wp_cache_get('plugins','plugins') ; $cache_plugins[''][$plugin_path] = $new_plugin ; wp_cache_set('plugins', $cache_plugins, $cache_plugins,'plugins') ; activate_plugin() befindet sich in wp-admin/includes/plugin.

You can use the register_activation_hook to register a plug-in that is to be executed when the plug-in is enabled. If a plug-in is enabled, the event'activate_PLUGINNAME' Hook is invoked. PLUGINNAME in the name of this hook replaces PLUGINNAME with the name of the plug-in, plus the option sub-directory. If, for example, the plug-in is found in wp-content/plugin/sampleplugin/sampleplugin/sample.php, then the name of this hooks becomes 'activate_sampleplugin/sample.php'.

The name of this hooks is'activate_sample.php' if the plug-in is just a single filename and is found (as usual) under wp-content/plugin/sample.php. It is a wrapper for the'activate_PLUGINNAME' operation and is simpler to use. Use this code: Aktivierungscode hier... register_activation_hook( __FILE__,'myplugin_activate'); This calls the call to the registration key myplugin_activate() when the plug-in is activated.

When your plug-in uses the single-ton classpattern, append the enable check mark as follows: register_activation_hook( __FILE__, array('MyPlugin','install') ) ); When the classphrase containing your enable function/method is in an extra filename, append your enable functions as follows: include_once dirname( __FILE__ ) .

It is not possible to call register_activation_hook() within a feature connected to the'plugins_loaded' or'init' cookies (or other cookies). Those check marks are invoked before the plug-in is load or enabled. If a plug-in is enabled, all enabled plug-ins are uploaded and then the plug-in is enabled. Check the box to activate the plug-in and the page will be immediately rerouted (see below).

When you are interested in doing something shortly after a plug-in has been enabled, it is important to keep in mind that the hooking operation redirects immediately after it has been triggered. Therefore, it is not possible to use add_action() or add_filter() types of call until the redirection is done (e.g. only two checkmarks are triggered after activating the plugin: 'activated_plugin' and 'shutdown').

When you use hot tags, you will notice that the command you give to register_activation_hook() does not have hot tag at the point where it is invoked, although you specify its hot tag within the command as: $myvar ='whatever'; < hot tag $myvar; < cho $myvar; × cho $myvar; // this will NOT be 'whatever'!

It is contained in the activate_plugin() command, so its "body" is not necessarily in the world. When you want a tag to be globally, you have to define it as such, and that means you use it everywhere and everywhere.

When you use it in the bulk of the plug-in, you must also globally define it there. Once enabled, your plug-in will be integrated by another feature and then your myplugin_activate() will be invoked within that feature (especially within the activate_plugin() feature) at the point where your plug-in will be enabled.

This check mark is now only triggered when the plug-in is activated by the current users and no longer when an automated plug-in is updated (#14915).
