I'm currently developing a plugin where I will restrict certain pages to the logged-in users only. I mean the normal pages we create in Wordpress.
I found this online but it does not seem to work for me.
function check_the_current_page(){
echo $slug = basename(get_permalink());
}
add_action( "init", "check_the_current_page" );
Another option I had was to detect current page id as shown in the code below. nothing gets printed on the screen, probably I'm using the wrong hook or something, someone help me
function check_the_current_page(){
global $post;
echo "Post id: ".$post->ID;
}
add_action( "init", "check_the_current_page" );
if only I'm able to get output in one of the above scenarios, then it would be very simple, but now nothing is being printed on the screen for both scenarios
Try This Code Work For Me global $post dosent work in init
function check_the_current_page() {
global $post;
echo "Post id: " . $post->ID;
}
add_action( "wp", "check_the_current_page" );

I have an issue that when i'm calling home_url($wp->request) in themes page or functions.php it works correctly, the out put is : http://localhost/WP_CUSTOM/tester , but when i'm calling in plugin the output is not correct : http://localhost/WP_CUSTOM .
This is i tried so far.
function init(){
global $wp;
$current_url = home_url( $wp->request );
print_r($current_url);
}
add_action('init','init');
I write these code in functions.php file of my plugin
That will depend on what it is that you are really trying to get.
global $wp;
home_url( $wp->request );
will generally give you the url of current page if the request is available. it is relative. ( a bit like get_permalink(), but not the same )
Also, in general, while in plugins it would be advised to use the wp get_*() functions, or in this case, get_home_url()
It would be better however if you will tell us what is thee url that you are trying to get and to what purpose. there might be better ways.
I want to add a little code to the "Before Header Content hook" but I don't know where that is... Can you please help me?
Try:
add_action('init', 'process_post');
function process_post()
{
echo "test";
}
this is a modified version of #ajay 's solution
if you are going to use this, then you have to make sure that the current user is not an admin using is_admin() function.. and only display it if he is not an admin ...
why !?
because if you didn't, it may mess up the wp-admin of your website..
add_action('init', 'process_post');
function process_post()
{
if (!is_admin()) {
echo "test";
}
}
This could be tricky simply because every theme differs with how the loop is displayed, however you could create a plugin to use the loop_start action, which is called before the first post of the standard WP loop:
add_action( 'loop_start', 'test_loop_start' );
function test_loop_start( $query ){
echo 'this is my inserted text';
}
Now using this would display it every single time the loop is called (whether on a page, a post, category page, search page, etc.), which you may not want.
add_action( 'loop_start', 'test_loop_start' );
function test_loop_start( $query ){
if(is_category() OR is_singular()) {
echo 'this is my inserted text';
}
}
I am currently creating a widget to display the registration form on a WordPress website that uses WooCommerce. For now, I only have 3 basic fields which are email, password, repeat password. I'm looking forward to add more WooCommerce fields, but want to solve that problem before jumping to the next step.
I'm having some problems with the messages output (wrong password, account already exists, etc).
I searched on the web and there was no shortcode already built for WooCommerce registration, beside their registration page. So I went ahead and created a shortcode, with a template part.
function custom_register_shortcode( $atts, $content ){
global $woocommerce;
$form = load_template_part('framework/views/register-form');
return $form;
}
add_shortcode( 'register', 'custom_register_shortcode' );
This is a snippet I use to get the template part inside a variable, since the default function would "echo" the content instead of "returning" it.
function load_template_part($template_name, $part_name=null) {
ob_start();
get_template_part($template_name, $part_name);
$var = ob_get_contents();
ob_end_clean();
return $var;
}
So, the problem is, when I call woocommerce_show_messages or $woocommerce->show_messages(); from my template part, nothing is showing, or if it is, it shows at the top of the page.
I did try to put the calls inside my shortcode function:
function custom_register_shortcode( $atts, $content ){
global $woocommerce;
$woocommerce->show_messages();
$form = load_template_part('framework/views/register-form');
return $form;
}
add_shortcode( 'register', 'custom_register_shortcode' );
Doing so, the message output inside the <head> tag, which is not what I want.
I tried to do the same trick with ob_start(), ob_get_contents() and ob_clean() but nothing would show. The variable would be empty.
I also did try to hook the woocommerce_show_messages to an action as saw in the core:
add_action( 'woocommerce_before_shop_loop', 'woocommerce_show_messages', 10 );
For something like:
add_action( 'before_registration_form', 'woocommerce_show_messages');
And I added this in my template-part:
<?php do_action('before_registration_form'); ?>
But I still can't manage to get the error messages show inside the box. It would always be inserted in the <head>
I will share final solution when everything is done.
Thanks for your time,
Julien
I finally got this working by hooking a custom function to an action which is called in my header.php
I guess hooking functions inside template part does not work as intended.
In header.php, I got this:
do_action('theme_after_header');
And here's the hooked function. Works perfectly.
function theme_show_messages(){
woocommerce_show_messages();
}
add_action('theme_after_header', 'theme_show_messages');
However, I will look into 'unhooking' the original show message function since it might show twice. Need to test some more ;)
You can also just use the [woocommerce_messages] shortcode in your template where you want it displayed
Replying to a bit of an old question, but you can also try the following:
$message = apply_filters( 'woocommerce_my_account_message', '' );
if ( ! empty( $message ) ) {
wc_add_notice( $message );
}
i'm working on a plugin that adds another parameter to feeds, i want to add a numberOfItems on the url and the feed returns that number of articles. I dont want to use the builtin option from WP Admin because the feed will be added on other websites with different number of items, it's a little bit complicated, the point is i need this implementation. i've added something like
function _my_custom_option( $option )
{
global $wp_query, $wp_rewrite;;
remove_filter( 'pre_option_posts_per_rss', '_my_custom_option' );
//$number = get_query_var('number');
$number = $wp_query->query_vars['numberOfItems'];
if(isset($number))
$option = $number;
else
$option = 10;
//$wp_rewrite->flush_rules();
add_filter( 'pre_option_posts_per_rss', '_my_custom_option' );
return $option;
}
add_filter( 'pre_option_posts_per_rss', '_my_custom_option' );
It seems that the feed is cached somehow and doesnt generate with the number of items, because when i add paged=2, it works. But if i change on page=2 numberOfItems with another number, it doesnt change. Plus, i added some junk text in wp-includes >feed-rss2.php just to verify if it cached or not. And it doesnt show after the first 2-3 page refreshes.
To be honest, i'm stuck, i don't know how to approach this, i've looked on the wordpress code and i dont see where the caching is done.
What about this?
function do_not_cache_feeds(&$feed) {
$feed->enable_cache(false);
}
add_action( 'wp_feed_options', 'do_not_cache_feeds' );
I am using developing a child theme for Woothemes' Canvas.
I am trying to use functions.php in the child theme to only use actions on my custom post type.
This code doesn't seem to be working:
add_action( 'woo_post_inside_after', 'my_geo_mashup' );
function my_geo_mashup() {
echo GeoMashup::map();
if ($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.
