Restricting Wordpress Admin Options to Admins - wordpress

I thought this would be an easy thing but many hours have gone by and still no results.
I am creating a Wordpress plug-in that should only appear in the dashboard if the user is an admin. I wrapped my hooks in the is_admin() method, but when I log in as a user who is just a subscriber, I still see the menu.
Isn't it just that easy???
Here's a code except starting right below the comment section to register the plugin... everything not shown is just functions doing their job ...
if( is_admin ){
add_action('admin_menu', 'ppm_talentexpo_add_page');
add_action('admin_menu', 'ppm_expos_submenu');
} // end is_admin
function ppm_talentexpo_add_page() {
$mypage = add_menu_page('Talent Expo', 'Talent Expos', 2, 'ppmtalentexpo', 'jwg_talentexpo_options_main_page', '/wp-admin/images/media-button-music.gif' , 21);
add_action( "admin_print_scripts-$mypage", 'jwg_ppmtalentexpo_admin_head' );
} // end function

It looks like you left out the parentheses when calling is_admin in the conditional.
Try
if( is_admin() ){
add_action('admin_menu', 'ppm_talentexpo_add_page');
add_action('admin_menu', 'ppm_expos_submenu');
}
Also if you're not using an older WordPress install, add_menu_page allows you to specify a capability that WordPress will check for. This lets WordPress manage showing the item or not.
So you can define a custom capabilty (or reuse an existing one), and the menu should take care of itself.
add_action('admin_menu', 'ppm_talentexpo_add_page');
add_action('admin_menu', 'ppm_expos_submenu');
function ppm_talentexpo_add_page() {
$mypage = add_menu_page('Talent Expo', 'Talent Expos', 'my_custom_talent_expos_capability', 'ppmtalentexpo', 'jwg_talentexpo_options_main_page', '/wp-admin/images/media-button-music.gif' , 21);
add_action( "admin_print_scripts-$mypage", 'jwg_ppmtalentexpo_admin_head' );
}

is wrong to add my code in wp admin page wordpress

I must to add new options and functions in post pages in admin panel. I call a new function in edit-form-advanced.php and edded this function in template.php file. The question is this wrong? Becouse my function is in one file with functions on wordpress. Or maybe must be in other file? but where i must call it?
For wp-content part i know and i make a child theme of parent theme, but i do not know what to do when i must add code in wp-admin part.
example:
edit-form-advanced.php
do_custom_boxes( null, $post );
and in template.php
function do_custom_boxes( $screen, $object ) {
global $wpdb;
$appTable = $wpdb->prefix . "post_panel";
$query = $wpdb->prepare("SELECT * FROM $appTable WHERE post_id = ".$_GET['post']." ", $screen);
$applications = $wpdb->get_results($query);
......
}
Short answer: Yes, it's wrong to do so. Whenever you update your WordPress you'll loose all your changes.
WordPress allows you to hook into its code, modify its behavior and many things.
Please read about actions and filters.
Basically, Actions allow you to fire a function when something happens in WordPress.
For example:
<?php
function do_something_when_admin_pages_init() {
// Do something here
}
add_action('admin_init', 'do_something_when_admin_pages_init')
Filters allow you to modify data/output of another function. It's like it let you step in the middle, do something with the data and then continue.
Example from the WordPress page:
<?php
function wporg_filter_title($title) {
return 'The ' . $title . ' was filtered';
}
add_filter('the_title', 'wporg_filter_title');
This modifies the title before it's printed.
So with those two ways of 'hooking' into the WordPress code, you can write your code in your theme's functions.php file, or write a Plugin (it's up to you).

Woocommerce woocommerce_order_status_processing trigger only in user side

Hi I would like to ask you guys if this is possible in Woocommerce hooks
the hook I'm using is this one,
woocommerce_order_status_processing
I want this hook only to be called in user side after payment, which is works ok but in the admin if I change the oder status, this hook is also triggering, can I disabled my custom hook in admin and will run/trigger only for the user side?
add_action( 'woocommerce_order_status_processing', 'order_extracode' );
function order_extracod( $order_id) {
.....
}
the above code is the function and hook I added, I tried !is_admin() but it is not working, and still processing this function in Admin Orders
thanks (TIA)
This hook will be executed every time there's a statu change.
What you can do is to decide if you want to execute the code in the front or in the Dashboard.
add_action( 'woocommerce_order_status_processing', 'order_extracode' );
function order_extracod( $order_id) {
if( ! is_admin()){
// Your code here
}
}
The only conditional tag to detect if you are in the dashboard or not is the is_admin()
WooCommere cannot tell the difference between who is triggering the woocommerce_order_status_processing action.
If you want something to happen when the user completes payment, you could try the woocommerce_payment_complete hook in abstract-wc-order.php.
Alternatively you can use current_user_can() function to determine the whether the hook can be executed or not, like this
if( !current_user_can( 'administrator' ) && !current_user_can( 'manage_options' ) ) {
//do your stuff
}

WooCommerce Registration Shortcode - Error messages problems

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 );
}

Hide page for logged in Users

I wanna do the following:
If a user is logged out, he can view the page id=10, if a user is logged in and view page id=10 he will be redirected to page id=5. I tried adding the below code into my header, but it didn't work.
add_action( 'init', 'check_redirect_page' );
function check_redirect_page() {
if ( is_user_logged_in() && is_page( 10 ) ) {
wp_redirect( get_permalink( 5 ) );
exit;
}
}
Try using the wp hook rather than init; WordPress won't have got far enough at init to know whether it's dealing with a particular page or not.
add_action( 'wp', 'check_redirect_page' );
From the Conditional Tags documentation:
Warning: You can only use conditional query tags after the
posts_selection action hook in WordPress (the wp action hook is the
first one through which you can use these conditionals). For themes,
this means the conditional tag will never work properly if you are
using it in the body of functions.php, i.e. outside of a function.

How do you remove or change the functionality of the Publish button on a custom WordPress post?

I have a custom post type and need keep the post status from getting set to 'Published' when you click the Publish button. Instead, it should work like the Save Draft button. So I either need to figure out how to just remove the Publish button so the user's can only click Save Draft our preferably, update the Publish button functionality so it doesn't set the post to publish.
You can use wordpress action hooks to modify default behaviors.
http://codex.wordpress.org/Function_Reference/add_action
In your case, you want to use the 'publish_post' hook.
So you can do
function dont_publish( $post_ID )
{
if(get_post_type($post_ID) == 'your_custom_type'){
exit;
}
}
//the dont_publish function will be called after the publish button is clicked
add_action( 'publish_post', 'dont_publish' );
The way it is above, nothing will happen at all if the publish button is clicked, but you can play around with the dont_publish function to get the results you want.
#PhoenixWing156 was close but one little change so the the other post types get updated as usual.
function dont_publish( $data , $postarr ) {
if($data['post_type'] == 'custom_post_type') {
$data['post_status'] = 'draft';
}
return $data;
}
add_filter('wp_insert_post_data' , 'dont_publish' , '99', 2);
The wp_insert_post_data hook is called before information about a post is saved to the database.
http://codex.wordpress.org/Plugin_API/Filter_Reference/wp_insert_post_data
You can try:
function dont_publish( $data , $postarr )
{
if($data['post_type'] == 'custom_post_type'){
$data['post_status'] = 'draft';
return $data;
}
}
add_filter('wp_insert_post_data' , 'dont_publish' , '99', 2);
WordPress provides the remove_meta_box() function exactly for this purpose.Just add this below code:-
add_action( 'admin_menu', function () {
remove_meta_box( 'submitdiv', 'Your_custom_post_type', 'side' );
} );
You could also disable the default saving metabox and add you own.
This is not documented well in the developer docs of wordpress.
To do this you have to hook into the "add_meta_boxes"-hook and in the hooked function yo have to call remove_meta_box('submitdiv','your-cpt','side');
The code should be something like this:
function your_cpt_metaboxes(){
remove_meta_box('submitdiv','your-cpt','side');
...
}
add_action('add_meta_boxes','function your_cpt_metaboxes');
your-cpt has to be changed to the name of your cpt of course.
I was also searching for this handy snippet and found it in the plugin Awesome Support.
The original saving metabox code can be found in /wp-admin/includes/metaboxes.php .
Just search for post_submit_meta_box (in WP 5.4 on line 22).
