I am having a small issue where i need to call add_action method which is conditional. Basically here, first checking whether the plugin active or not by admin_init action. If true then i need another add_action call from that action.
Please find the scenario what i am looking for:
function check_some_other_plugin() {
if ( is_plugin_active('some-plugin.php') ) {
//if true then vc_before_init action will run
add_action( 'vc_before_init', 'vc_master_home_slider' );
}
}
add_action( 'admin_init', 'check_some_other_plugin' );
function vc_master_home_slider() {
//my stuff
}
I am really eager to know how this things can be possible. Thanks in advance.

I've got two functions:
add_action( 'woocommerce_order_status_completed' , 'after_order_complete' , 10);
function after_order_complete( $order_id )
{
error_log("woocommerce_order_status_completed", 0);
}
add_action( 'wp_login', 'after_login', 10, 2);
function after_login( $user_login, $user ) {
error_log("wp_login", 0);
}
that I can't seem to get called, tried in a plugin and functions.php but they never fire and no errors are logged.
How is it I debug this to find out why they fail or does anyone know how to get these to work?
In the same code I have another add_action but this time using user_register and that works as expected from plugin or functions.php
Edit:
I have the wp_login figured out, action does get called but only when first visiting the back end, site is front end only for users so used membership system hook instead.
I want my plugin to register a script only in a certain page.
For example, inside my plugin file I want to write something like this:
if (is_page()) {
$pageid_current = get_the_ID();
$page_slug = get_post($pageid_current)->post_name;
if ($page_slug == 'articles'){
wp_register_script('myscript', '/someurl/main.js');
}
}
But I get the error:
is_page was called incorrectly. Conditional query tags do not work
before the query is run. Before then, they always return false. Please
see Debugging in WordPress for more information. (This message was
added in version 3.1.)
How can I, inside of a plugin, register a script in a certain page?
is_page() only work within template files.
And to use it within plugin files, you need to use it with the combination of template_redirect action hook.
This action hook executes just before WordPress determines which template page to load.
So following snippet would work:
add_action( 'template_redirect', 'plugin_is_page' );
function plugin_is_page() {
if ( is_page( 'articles' ) ) {
wp_register_script( 'my-js-handler', '/someurl/main.js', [], '1.0.0', true );
}
}
You could use is_page() after template redirect so you need to add in the hook like this :
add_action('template_redirect','your_function');
function your_function(){
if ( is_page('test') ) {
// do you thing.
}
}
You must register your script as if you want it to work everywhere.
You can de-register it after the job is done, like this:
function deregister_my_script() {
if (!is_page('page-d-exemple') ) {
wp_deregister_script( 'custom-script-1' );
}
}
add_action('wp_print_scripts', 'deregister_my_script', 100 );
I'm writing a plugin and I need to display a piece of text in the WP page, but not in the admin area. How can I do so?
I tried this in the construct:
add_action( 'init', array( $this, 'initPage' ) )
and then:
public function initPage() {
echo 'hello';
}
but the text is displayed also in the admin area. Is there a way to do this? It would be the opposite of the action admin_init I assume.
Proper way to handle it: is_admin()
http://codex.wordpress.org/Function_Reference/is_admin
if(is_admin()) { // do nothing } else {
// function you want to execute.
}
I solved this by adding it to a shortcode action. Like this:
add_shortcode( 'myPlugin', array( $this, 'shortcode' ) );
and:
public function shortcode( $atts ) {
return 'hello';
}
With the above code, 'hello' will only display on the front-end. Not sure if that's the cleaner way to do it, but does the job.
There is no "front-end-only" version of init, however you probably don't want to be doing any output at the init action anyway.
What exactly are you trying to do? Usually, you use an action hook for specific types of things, and causing output very early at something like "init" is rare and weird.
I'm trying to figure out if the same function is hooked onto multiple actions, can I figure out which action calls it?
I'd like to send out an API call when a user is created and deleted; the functionality in both cases is the same except one data point would be different based on if its created or deleted. It doesn't feel right making two identical functions with only one difference, but I'm not sure how else I can do it.
Advice?
That's the function current_filter():
add_action( 'plugins_loaded', 'common_action' );
add_action( 'admin_init', 'common_action' );
function common_action()
{
switch( current_filter() )
{
case 'plugins_loaded':
// do_something( 'Plugins loaded' );
break;
case 'admin_init':
// do_another_thing( 'Admin init' );
break;
}
}
I had the same question - when running a function, which action was triggering it? The key is $wp_current_filter.
Example:
// Both of these will call the same function
do_action('wp', 'my_function');
do_action('init', 'my_function');
function my_function() {
// How do I know if this was 'init', 'wp', or some other hook?
// Global in the WordPress variable $wp_filter
global $wp_current_filter;
if ($wp_current_filter == 'wp' || in_array('wp', $wp_current_filter)) {
// Do my "wp" based stuff....
}
if ($wp_current_filter == 'init' || in_array('init', $wp_current_filter)) {
// Do my "init" based stuff....
}
}
Note: This is a lousy use-case example, but it conveys the principles!
I am using developing a child theme for Woothemes' Canvas.
I am trying to use functions.php in the child theme to only use actions on my custom post type.
This code doesn't seem to be working:
add_action( 'woo_post_inside_after', 'my_geo_mashup' );
function my_geo_mashup() {
echo GeoMashup::map();
if ($post->post_type == 'listings') {
//My function
}
}
add_action( 'woo_post_inside_before', 'listings_nivo' );
function listings_nivo() {
echo do_shortcode('[nivo source="current-post" ]');
if ($post->post_type == 'listings') {
//My function
}
}
So, I'm unsure how to get the above to work properly and only show these items on the custom post type, or only for the custom post type template single-listings.php (as I only want the map and slider to show on the actual post, not on the blog page (archive.php)
Rather than making the entire $post object global, you can just make $post_type global instead. Ex below.
I'm not exactly sure where that function is being loaded, but make sure you hook somewhere within the post. If the action is before, as far as I know and from experience, the post variable will be null.
Just as a test, try running the action in wp_footer Ex. add_action( 'wp_footer', 'listings_nivo' );
See if that yeilds any results.
if echoing var_dump($post) is still null, well, not sure where to go from there.
So you can try running the below, then run the action in the appropriate place if it works:
function listings_nivo() {
echo do_shortcode('[nivo source="current-post" ]');
global $post_type;
// Diagnostic purposes
echo var_dump($post_type);
if ($post_type == 'listings') {
//My function
}
}
add_action( 'wp_footer', 'listings_nivo' );
Check your error log or turn wp_debug to true in your wp-config.php file if nothing else to see if anything else is going on.
Best of luck!
Inside your function, try adding global $post;. Then to see what you are getting with $post->post_type echo it out to the screen. As long as this gives you "listings", your code should work. If not, there's probably another issue at play.
