The price code is:

                        <td class="product-price">

                            if( $product_obj->price != '0' ) {
                                if( get_option( 'woocommerce_tax_display_cart' ) == 'excl' )
                                    { echo apply_filters( 'woocommerce_cart_item_price_html', woocommerce_price( $product_obj->get_price_excluding_tax() ), $values, '' ); }

                            }
                            ?>
                        </td>
                    <?php endif ?>

Answer:

Looking at your code I would suggest you add

$product_obj->get_sku();

Currently it seems like data is not loaded to the $product, but instead using $product_obj(etc.)

Question 2:

How to edit wishlist of current user?

Users are not able to edit their wishlist profile by clicking on 'edit wishlist' button when the user tries to click on the button it returns an error saying the wish list id not found, but actually, it is the user.id, not the wishlist.id. The user is asking for its solution.

The code is given below

<div class="post3">
    <h1><%= t('.mwg')%></h1><br />
    <div id = "table-2">
    <table width="240" >
<tbody>
        <% Wishlist.where(:user_id => @user).each do |wishlist| %>
        <tr><td width="30"><b>1:</b></td><td><%= wishlist.number_1 %></td></tr>
        <tr><td width="30"><b>2:</b></td><td><%= wishlist.number_2 %></td></tr>
        <tr><td width="30"><b>3:</b></td><td><%= wishlist.number_3 %></td></tr>
        <tr><td width="30"><b>4:</b></td><td><%= wishlist.number_4 %></td></tr>
        <tr><td width="30"><b>5:</b></td><td><%= wishlist.number_5 %></td></tr>
    </tbody> 
   </table>
  </div>
    <%if current_user %>
       <% if current_user.id == wishlist.user_id %>
         <div id="text3"><%= link_to t('.edit'), edit_wishlist_path(@wishlist) %></div><br />
       <%end%>
    <%end%>
<%end%>

The user tried to change current_user.id == wishlist.user_id the line to the following:

<% if current_user.id == @wishlist.user_id %>

But getting the same error of undefined method user_id

Currently, the code returns the wishlist_id, but user wants to return the user_id

 Answer:

You just need to call edit_wishlist_path(wishlist), not @wishlist.

Question 3

The wishlist section disappears from the site when all items removed from it, User want to show wishlist section even if there is no item in it with a text "Add some items to your wishlist" how to do it?

User tried the .phtml file for solving the issue, but it is not working

Answer:

In the newer versions after 1.4.2 the wishlist class has been changed, the new class is:

* @deprecated after 1.4.2.0
     * @see Mage_Wishlist_Block_Links::__construct
     *
     * @return array
     */
    public function addWishlistLink()
    {
        return $this;
    } 

The above code is just for general information; the actual code which may solve your issue is given below

/**
     * Add link on wishlist page in parent block
     *
     * @return Mage_Wishlist_Block_Links
     */
    public function addWishlistLink()
    {
        $parentBlock = $this->getParentBlock();
        if ($parentBlock && $this->helper('wishlist')->isAllow()) {
            $count = $this->helper('wishlist')->getItemCount();
            if ($count > 1) {
                $text = $this->__('My Wishlist (%d items)', $count);
            }
            else if ($count == 1) {
                $text = $this->__('My Wishlist (%d item)', $count);
            }
            else {
                $text = $this->__('My Wishlist');
            }
            $parentBlock->addLink($text, 'wishlist', $text, true, array(), 30, null, 'class="top-link-wishlist"');
        }
        return $this;
    }

Question 4

The user has a custom wishlist plugin and a step by step form where users can choose a number of lists (1 to 10) as well as enter title and descriptions for lists, at the end, there is an Ajax request on the form. The user wants to add these generated lists to the database.

User tried  wp_insert_post( $my_post ), but it did’nt work.

Answer:

You can try this if the code mentioned above is not working for you

WC_Wishlists_Wishlist::create_list($tittle));

Question 5

I have a Wishlist plugin code is written in Javascript. The plugin adds wishlist items successfully in the list but doesn't display any confirmation/success message after adding an item in the wishlist.

The user using the code given below for displaying success message, but it does not work

function AddItem(ToDoItem) {
    if ((ToDoItem != null) && (ToDoItem != "undefined" )) {
        NumToDoItems++;
        SetCookie('PT_ToDoItem'+NumToDoItems, ToDoItem, exp);
        SetCookie('PT_NumToDoList',NumToDoItems, exp);
        $(window).humanMsg('Added '+ToDoItem+' to Wishlist');
    }
}

How to resolve this issue?

The HTML code is:

<div class="add-to-wishlist">
<a href="javascript:AddItem('<?php print htmlentities($title, ENT_QUOTES); ?>')">
<img class="add-to-wishlist" src="/images/add-to-wishlist-button.gif" border="0" /></a>
</div>

jQuery file

(function($, window){

$.fn.humanMsg = function( message, options ) {
    return this.each(function(){
        var container = this == window || this == document ? document.body : this;
        !$.data(container, 'humanMsg') && $.data(container, 'humanMsg', new     $.humanMsg (container, message, options) );
    });
};

$.humanMsg = function( container, message, options ) {
    if (typeof message == 'object') {
    options = message;
    message = null;
}

var s = $.extend({}, $.humanMsg.defaults, options);

var $m,
    sizeContainer = container == document.body ? window : container;

$m = $('<div class="humanized-message '+s.addClass+'"/>')
.html(message || s.message)
.click(remove)
.appendTo(container);

$m.css({
    display: 'none',
    visibility: 'visible',
    top: ($(sizeContainer).height()-$m.innerHeight())/2,
    left: ($(sizeContainer).width()-$m.innerWidth())/2
})
.fadeIn(s.speed);

s.autoHide && setTimeout(remove, s.autoHide);   

function remove() {
    $m.fadeOut(s.speed, function(){
        $m.remove();
        $.removeData(container, 'humanMsg');
    });
}

};

$.humanMsg.defaults = {
message: 'no message was set',
autoHide: 3000,
addClass: '',
speed: 300
};

})(jQuery, this);

Below is the error that occurs instead of showing success message

Uncaught TypeError: Property '$' of object [object Window] is not a function 
(anonymous function)
closing script tag manually 

Answer:

Looking on the error, it indicates that your jQuery file is not included in the script, please have a look on your jQuery file
