I am using Wordpress for my online shop.
I have a problem. On the page with the product, I added a button for comparing the products. All is well but I want that after pressing the button, it becomes invisible.
<?php
$session_data = $be_product_compare->session->get_session_cookie();
if( is_array( $session_data ) && in_array( get_the_ID(), $session_data ) )
{ echo BE_Compare_Products::display_button( ''.get_the_ID() . '' );
}
else
{
echo ' disabled=disabled ';
}
?>
And I get
Uncaught Error: Call to a member function get_session_cookie() on null
in
Can someone help me finish with this Button?

I am using WPLMS theme for a course management website. I am using following code to display a button in the details page.
add_filter('wplms_before_course_description','custom_add_second_button');
function custom_add_second_button($course_details){
$custom_link = get_post_meta(get_the_ID(),'Custom_button_link',true);
if(isset($custom_link)){
echo '<a class="full button" href="'.$custom_link.'"><span class="vicon vicon-shopping-cart"></span> Buy This Course</a>';
return $course_details;
}
return $course_details;
}
This is to show a custom add to cart button beside the title of the course. Now what I want is if a student has already purchased this course, this button will not come up. Kindly help me to achieve my goal please. Thanks in advance.
You can use WC wc_customer_bought_product() function to check whether the customer already bought it or not.
add_filter( 'wplms_before_course_description','custom_add_second_button' );
function custom_add_second_button($course_details){
global $product;
$custom_link = get_post_meta( get_the_ID(), 'Custom_button_link', true );
if( is_user_logged_in() ){
$current_user = wp_get_current_user();
if( !wc_customer_bought_product( $current_user->user_email, $current_user->ID, $product->get_id() ) && isset( $custom_link ) ){
echo '<a class="full button" href="'.$custom_link.'"><span class="vicon vicon-shopping-cart"></span> Buy This Course</a>';
return $course_details;
}
}else{
if( isset( $custom_link ) ){
echo '<a class="full button" href="'.$custom_link.'"><span class="vicon vicon-shopping-cart"></span> Buy This Course</a>';
return $course_details;
}
}
return $course_details;
}
USEFUL LINKS.
wc_customer_bought_product()
You can use the function bp_course_is_member($course_id,$user_id)) to check if the user is already a member of the course.
I am using a function to add custom meta to products. I have used the following hooks for SHOW on Product Loop woocommerce_after_shop_loop_item and Product Single Page woocommerce_product_meta_end.
So, when applying to get the same results on CART PAGE product/item by using the hook
woocommerce_after_cart_item_name it doesn’t work with no results.
Why isn’t the hook woocommerce_after_cart_item_name working if it works with the other previous hooks mentioned?
This the code I am using. I just change the hook to make it to show in Product Loop and Product Single Page, need it to show on cart Products as well. I was just wondering why it doesn't work with cart item hook..
public function woocommerce_after_cart_item_name()
{
global $product;
if ( !PluginOptions::value('shop_season') && !PluginOptions::value('shop_car_type') )
return;
$product_id = $product->get_id();
$season = get_post_meta( $product_id, 'season', true );
$car_type = get_post_meta( $product_id, 'car_type', true );
$tips_seasons = $this->ui_tips_season();
$tips_car_types = $this->ui_tips_car_types();
?>
<div class="tyre-details tyre-tips">
<?php if ( PluginOptions::value('shop_season') && $season ): ?>
<?php echo $tips_seasons[ strtolower($season) ]; ?>
<?php endif ?>
<?php if ( PluginOptions::value('shop_car_type') && $car_type ): ?>
<?php echo $tips_car_types[ strtolower($car_type) ]; ?>
<?php endif ?>
</div>
<?php
}
It is from a plugin. I was just given this code from woocommerce support but i do not know how to complete it. He says to replace with my meta_keys in the code which I will post below here. Can you help me finish this? or tell me where I need to replace. My meta_keys are $season and $car-type but i don't know how to apply with the code provided by woocommerce.
// Display custom cart item meta data (in cart and checkout)
add_filter( 'woocommerce_get_item_data', 'display_cart_item_custom_meta_data', 10, 2 );
function display_cart_item_custom_meta_data( $item_data, $cart_item ) {
$meta_key = 'PR CODE';
if ( isset($cart_item['add_size']) && isset($cart_item['add_size'] [$meta_key]) ) {
$item_data[] = array(
'key' => $meta_key,
'value' => $cart_item['add_size'][$meta_key],
);
}
return $item_data;
}
// Save cart item custom meta as order item meta data and display it everywhere on orders and email notifications.
add_action( 'woocommerce_checkout_create_order_line_item', 'save_cart_item_custom_meta_as_order_item_meta', 10, 4 );
function save_cart_item_custom_meta_as_order_item_meta( $item, $cart_item_key, $values, $order ) {
$meta_key = 'PR CODE';
if ( isset($values['add_size']) && isset($values['add_size'][$meta_key]) ) {
$item->update_meta_data( $meta_key, $values['add_size'][$meta_key] );
}
}
I located the ClassName (class FeatureTyreTips) and added that to the code you provided. I entered this in functions.php and it said fatal error when loading the cart page. I also tried placing it in the cart.php with same results...and I tried in the same plugin file where this code came from originally. All 3 locations did not work...only difference was that it did not show fatal error when adding and activating your new code in the plugin file when loading cart page. Any ideas? grazie Vdgeatano
The "Fatal Error" is most likely due to the fact that "the non-static method cannot be called statically": PHP - Static methods
I have now corrected the code.
Considering that the class name that was missing in your code is FeatureTyreTips, the correct code to add some text after the product name is:
add_action( 'woocommerce_after_cart_item_name', 'add_custom_text_after_cart_item_name', 10, 2 );
function add_custom_text_after_cart_item_name( $cart_item, $cart_item_key ) {
// create an instance of the "PluginOptions" class
$PluginOptions = new PluginOptions();
if ( ! $PluginOptions->value( 'shop_season' ) && ! $PluginOptions->value( 'shop_car_type' ) ) {
return;
}
$product = $cart_item['data'];
$season = get_post_meta( $product->get_id(), 'season', true );
$car_type = get_post_meta( $product->get_id(), 'car_type', true );
// create an instance of the "FeatureTyreTips" class
$FeatureTyreTips = new FeatureTyreTips();
$tips_seasons = $FeatureTyreTips->ui_tips_season();
$tips_car_types = $FeatureTyreTips->ui_tips_car_types();
if ( ! $PluginOptions->value('shop_season') || ! $season ) {
$season = '';
}
if ( ! $PluginOptions->value('shop_car_type') || ! $car_type ) {
$car_type = '';
}
$html = '<div class="tyre-details tyre-tips">' . trim( $season . ' ' . $car_type ) . '</div>';
echo $html;
}
The code has been tested (where possible) and works.It needs to be added to your theme's functions.php file or in your plugin.
I'm using a plugin for wordpress-woocommerce called Woocommerce Cart PDF (https://wordpress.org/plugins/wc-cart-pdf/). It generates a pdf-link of the current cart, but is located on the cart page.
I have a combined cart and checkout page so the link does not appear on my website. I don't have the knowledge on how to edit the plugin files myself for it to appear on my cart page.
I've tried the wordpress plugin support forum for this specific plugin, but no answer.

if( ! function_exists( 'WC' ) ) {

<?php esc_html_e( 'Download Cart as PDF', 'wc-cart-pdf' ); ?>

This might be the incorrect part of the functions in the plugin, but I hop I got it right.
The wc_cart_pdf_process_download() function isn't really relevant. The comment states that it "Generates the PDF for download". What it's doing is responding when the user visits the PDF link by generating the requested PDF file. The important function is the one beneath that, wc_cart_pdf_button().
Now that we know the function we're interested in, what's next? In your question, you suggested editing the plugin files however it's important to avoid doing that. Editing your plugin files is a sure-fire way to guarantee the changes you make get overwritten the next time you update.
You have a couple of options:
Create a mini feature plugin.
Add the code to the bottom of your (hopefully child) theme's functions.php file.
The first option would be the recommended approach but that's going to take us well beyond the scope of the question. Placing the code in a child theme's functions.php file will be adequate for getting you up and running.
Okay, so now we know what the code we want to modify is and where we're going to store those modifications. Let's break down the actual code:
if( ! is_cart() || WC()->cart->is_empty() ) {
return;
}
This checks two things, are we on the cart page and does the cart contain items? If either is false, we're going to bail out early. You're on the checkout page, not the cart page, so even if this function were to be called, it wouldn't make it past this conditional.
<a href="<?php echo esc_url( wp_nonce_url( add_query_arg( array( 'cart-pdf' => '1' ), wc_get_cart_url() ), 'cart-pdf' ) );?>" class="cart-pdf-button button" target="_blank">
<?php esc_html_e( 'Download Cart as PDF', 'wc-cart-pdf' ); ?>
</a>
If those two previous checks passed, generate the button output.
add_action( 'woocommerce_proceed_to_checkout', 'wc_cart_pdf_button', 21 );
This executes the code on the woocommerce_proceed_to_checkout hook which fires after the cart totals on the cart page. The same action is used by the checkout button itself.
We need to write our own function that displays that same output on the checkout page. Without knowing where you'd like the button to appear, I can't suggest which action to use. I'm using woocommerce_checkout_order_review with a priority that'll put it between the order table and the payment options. If you need to reposition it, you'll have to go through those hooks and find somewhere that feels appropriate.
You did mention in your question that this is necessary because you have your cart and checkout pages combined. You may require a completely different hook, again there's no way for me to know based on your question alone.
Here's the final code:
function stackoverflow_wc_checkout_pdf_button() {
// We're on the checkout page based on the action.
// Highly unlikely we need the is_empty() check but it can't hurt if you may find yourself reusing elsewhere.
if ( WC()->cart->is_empty() ) {
return;
} ?>
<a href="<?php echo esc_url( wp_nonce_url( add_query_arg( array( 'cart-pdf' => '1' ), wc_get_cart_url() ), 'cart-pdf' ) );?>" class="cart-pdf-button button" target="_blank">
<?php esc_html_e( 'Download Cart as PDF', 'wc-cart-pdf' ); ?>
</a>
<?php
}
add_action( 'woocommerce_checkout_order_review', 'stackoverflow_wc_checkout_pdf_button', 15 );
i got this code from researching and trying to modify it but no luck. I want the last item in yoast breamcrumbs not to appear on single pages only
if ( is_single() ) {
/*Remove Last item in Yoast SEO Breadcrumb */
function adjust_single_breadcrumb( $link_output) {
if(strpos( $link_output, 'breadcrumb_last' ) !== false ) {
$link_output = '';
}
return $link_output;
}
add_filter('wpseo_breadcrumb_single_link', 'adjust_single_breadcrumb' );
};
I tried adding if is single in between the function and also this
if(strpos( $link_output, 'breadcrumb_last' ) !== false && is_single) {
unfortunately, the whole breadcrumb disappears.
with this code, you can remove post title in single page.
add_filter('wpseo_breadcrumb_single_link_info', 'remove_post_title_wpseo_breadcrumb', 10, 3);
function remove_post_title_wpseo_breadcrumb($link_info, $index, $crumbs)
{
if (is_singular() && isset($link_info['id']))
return [];
return $link_info;
}
Updated: In the latest version above code does not work perfectly.
for this reason, I removed the last item with regex:
function getBreadcrumb() {
if ( function_exists( 'yoast_breadcrumb' ) ) {
ob_start();
yoast_breadcrumb( '<p id="breadcrumb" class="meta-info">', '</p>' );
$breadcrumb = trim( ob_get_clean() );
if ( is_singular() )
$breadcrumb = trim( preg_replace( '/ ' . WPSEO_Options::get( 'breadcrumbs-sep' ) . ' <span class="breadcrumb_last" aria-current="page">(.*)<\/span>/i', '',
$breadcrumb ) );
echo $breadcrumb;
}
}
And call the function anywhere you want:
<?php getBreadcrumb() ?>
I am no PHP programmer therefore I have been scratching my head for two hours on this issue as there seems to be many ways of doing it. None of which I managed to get working because of my poor PHP/Wordpress syntax and logic knowledge.
What is the best way to create and call a function that loads a different value for <?php bloginfo('name') ?> only on top level pages? i.e. top level menu headings.
I was wondering if there would be the possibility of doing something along these lines:
<?php
if ( is_page( 'about' ) || == $post->post_parent ) {
bloginfo = 'about';
} elseif ( is_page( 'work' ) || == $post->post_parent ) {
bloginfo = 'work';
} elseif ( is_page( 'contact' ) || == $post->post_parent ) {
bloginfo = 'contact';
} else {
bloginfo('name');
}
?>
Please treat it as pseudo code as I am still familiarizing myself with the wordpress and PHP codex/syntax, hence why I cannot get anything to work. But basically, what I need to do is use the main nav link names as the bloginfo name for every page in their section. Anything else is an exception which defaults back to the home bloginfo name.
Would it be easier to try to parse the nav link titles themselves into the function?
Please help if you can!
UPDATE
I have completely ditched the previous option and went the following route:
<?php if (is_page() || is_single( array( 62, 57, 51, 8 ) )) {
echo wp_title('');
}
else{
$category = get_the_category();
echo $category[0]->cat_name;
}?>
It is kind of botched but after reading lots of reference material on the wordpress site, I think I am beginning to understand the syntax. So, instead of targeting bloginfo() I am now targeting the page title. However I do not want the posts to have a huge title therefore I am making all pages other than top level "pages" pick up the first category instead, except for a handful of posts which are in fact custom pages, so need to display the wp_title value.
If anyone has any tips on turning this into a more flexible/efficient function please drop a post otherwise I will make this as resolved in a couple of hours.
the syntax would be
<?php
if ( is_page( 'about' ) || == $post->post_parent ) {
bloginfo('about');
} elseif ( is_page( 'work' ) || == $post->post_parent ) {
bloginfo('work');
} elseif ( is_page( 'contact' ) || == $post->post_parent ) {
bloginfo('contact');
} else {
bloginfo('name');
}
?>
but there are no such parameters like about,work,contact to the bloginfo function in wordpress.
For more information on bloginfo, please check the this url -> http://codex.wordpress.org/Function_Reference/bloginfo
You may try this to filter/change the name using bloginfo filter (just add this code snippet in your functions.php file)
function my_custom_blogname( $output, $show )
{
if( $show == 'name' )
{
if( is_page('about') ) $output = 'It\'s my about page';
if( is_page('work') ) $output = 'It\'s my work page';
if( is_page('contact') ) $output = 'It\'s my contact page';
}
return $output;
}
add_filter('bloginfo', 'my_custom_blogname', 10, 2);
Update : Also you can check if the page is parent/top lavel page using
if( !$post->post_parent ) // To check only if it's a parent/top lavel page
if( is_page('about') && !$post->post_parent ) $output = 'about'; // To check if it's a parent/top lavel page and about page
