    A quick preview of the modified layout for the first section of the page (pending your response re the 'search' button.

    Attachment 19591
    Strelitzia, I really apologize for the delay in responding to this and your probable loss of steam. Let me just say that a lot has/had happened that weekend and in a way still recovering from those events. Some time was necessary to mentally review what had happened in that area and why there were two buttons to perform the same action.

    So, it somewhat went like this: wanted to provide a "tool" that was consistent across other operations within the ZC software and wanted to make updating it as easy as possible in the event that its use/creation changed within the ZC source code. So, it seemed that the best way to accommodate that was to reuse existing code as much and in the same way as possible. In doing so, I was also trying to work through a specific issue related to using these additional dropdowns (I don't think that even still that I have fully/successfully addressed all that I wanted to address) so had attempted to duplicate the code even though I may have also had an alternate action button that did the same thing. Then there was also the desire to try to ensure that the page passed html validation (I think with the duplicate buttons as they were in that area that two buttons had the same id parameter which doesn't pass validation).

    Anyways, I wanted to be sure that removal of one or the other button would still fully support the operation even if the look was improved. I hadn't quite finished that review when I was pulled away. To me it looks right and good and I would think that the operation would be improved with the "loss" of one or the other buttons.

    As for removal of one of the buttons... So, I have a few ideas about it and at least a partial reason for them both to be present/exist... So the removal of the search button would mean that it would be present unless we were looking at and have selected a product from the product list... Even with nothing else in mind, that seems like a lot of logic to address... The alternate being that the display button not be shown in that same condition, but then in use, selecting a product from the list makes one question "where" to make a selection on screen. Then there is one of the other reasons I keep the text of the search in the search field with the search button next to it is that the search "criteria" is clickable (copy/paste) and can be used elsewhere in the ZC system regardless of how the URI is formatted/generated. While a ***VERY*** rudimentary search facility is used, one could amplify how it works and the results, so I don't really want to remove the search button per se because one could possibly support (add code for) searching on specific attribute criteria or other aspects and it would be intuitive to click the search button next to that search text...

    I guess I would say, even though the code looks the "same" for the two, these clickable options are provided based on an end user perspective of what makes sense and offers functionality.

    I'll pick up the interface changes as soon as I get some time.

    On a separate note, I've found that fpdf generates an error when creating an invoice for items with a custom id since updating SBA.

    The error logged is
    Code:
    PHP Fatal error: Uncaught Error: Call to undefined function zen_get_customid() in /fpdf/genpdf.php:161
    I suspect that's due to you having moved zen_get_customid() from includes/functions/extra_functions/products_with_attributes.php to includes/classes/class.products_with_attributes_class_stock.php

    What is the recommended fix for this issue?

    Prepend your call to zen_get_customid() with: $_SESSION['pwas_class2']->
    so

    zen_get_customid()

    would become:

    $_SESSION['pwas_class2']->zen_get_customid()

    Did a little research on the message that is logged.

    Appears that the message is related to the "sequence" of session_start and use of session variables. That said, I wouldn't (necessarily) expect an issue if includes/application_top.php were loaded before getting to this point and also, the fact that the class is used as a session variable is something I *do* want to change, which was done as a minor work around to a portion of the checkout process.

    So the real question here is, when accessing this "file", how does it interact with the rest of Zen Cart? It could be possible to "prepare" the variable for use here (actually before the loop), but understanding the integration really helps such as is this on the admin side, is there some sort of load point at which it is brought in and how does that load point compare to what SBA does?

    On another side note, I see that only a single option value is ever presented to the zen_get_customid method. Are all product being offered where each option value is listed uniquely and there are no combined option values? Are both types being populated and only the single option value is being given a customid? The method supports being handed all of the option values associated with the product and then providing a sort of "formatted" customid.

    The file in question is invoked when an order is placed so that it can generate a pdf invoice to attach to the order confirmation email.
    Code:
    require_once(DIR_FS_CATALOG . 'fpdf/genpdf.php');
    is located in the order class, right before the //send additional emails code block.

    The directory 'fpdf' is in the site root, and full content of that file is
    Code:
    <?php
    // Process order totals
    if (!isset($order_totals) || isset($order_totals) && !is_array($order_totals) || isset($order_totals) && is_array($order_totals) && sizeof($order_totals) < 1)  $order_totals = $order_total_modules->process();
    if (is_array($order_totals)) {
    	foreach ($order_totals as $totals) {
    		$pdf_totals[$totals['code']] = $totals['value'];
    	}
    }
    
    if (isset($pdf_totals['ot_coupon'])) {
    	$discount_coupon = number_format($pdf_totals['ot_coupon'], 2, '.', '');
    	unset($pdf_totals['ot_coupon']);
    }
    if (isset($pdf_totals['ot_gv'])) {
    	$gift_certificate = number_format($pdf_totals['ot_gv'], 2, '.', '');
    	unset($pdf_totals['ot_gv']);
    }

    }
    So, I don't see if/how perhaps the $_SESSION is affected, but my idea to address this (as a work around which is not always the best way to implement) is to modify:
    Code:
    // $total = 0.00;
    
    for ($i = 0; $i < sizeof($this->products); $i++) {
        $attribute_customid = '';
        $attribute_names = array();
        $x = strip_tags($this->products[$i]['name']);
        
        // Process attributes
        if (isset($this->products[$i]['attributes']) && sizeof($this->products[$i]['attributes']) > 0) {
            foreach ($this->products[$i]['attributes'] as $attributes) {
                $attribute_names[] = $attributes['option'] . ': ' . $attributes['value'];
            
                $attribute_customid = $_SESSION['pwas_class2']->zen_get_customid($this->products[$i]['id'], array($attributes['value_id']));
            }
            
            if (isset($attribute_names) && is_array($attribute_names)) {
                $attribute_string = implode(', ', $attribute_names);
                $x .= ' ' . $attribute_string;
            }
        }
        
        $y = $this->products[$i]['qty'];
        $z = ($this->products[$i]['final_price'] > 0 ? $this->products[$i]['final_price'] : $this->products[$i]['price']);
        $t = $this->products[$i]['tax'];
        $m = ($this->products[$i]['model'] == '' && $attribute_customid != '' ? $attribute_customid : $this->products[$i]['model']);
        $x = str_replace("<br>", "", $x );
    
        $itemname = "$y x $x";
        $totalexvat = $z * $y;
        $totalcost = (zen_add_tax($z, $t) * $y) + zen_add_tax($this->products[$i]['onetime_charges'], $t);
    
        $thistax = zen_calculate_tax($z, $t);
        $pwt = $z + $thistax;
        // $totaltax += zen_calculate_tax($z, $t) * $this->products[$i]['qty'];
        
        $z = number_format($z, 2, '.', '');
        $totalcost = number_format($totalcost, 2, '.', '');
        $pwt = number_format($pwt, 2, '.', '');
        // $totaltax = number_format($totaltax, 2, '.', '');
        $totalexvat = number_format($totalexvat, 2, '.', '');
        $t = $t . "%";
        // $total += $totalcost;
        $lines[$i] = "$itemname|$m|$t|$pwt|$totalcost";
    }
    To add the following that is in blue:
    Code:
    // $total = 0.00;
    
    if (!class_exists('products_with_attributes_class_stock')) {
        include_once DIR_FS_CATALOG . DIR_WS_CLASSES . 'class.products_with_attributes_class_stock.php';
    }
    if (empty($_SESSION['pwas_class2'])) {
        $_SESSION['pwas_class2'] = new products_with_attributes_class_stock();
    }
    
    for ($i = 0; $i < sizeof($this->products); $i++) {
        $attribute_customid = '';
        $attribute_names = array();
        $x = strip_tags($this->products[$i]['name']);
        
        // Process attributes
        if (isset($this->products[$i]['attributes']) && sizeof($this->products[$i]['attributes']) > 0) {
            foreach ($this->products[$i]['attributes'] as $attributes) {
                $attribute_names[] = $attributes['option'] . ': ' . $attributes['value'];
            
                $attribute_customid = $_SESSION['pwas_class2']->zen_get_customid($this->products[$i]['id'], array($attributes['value_id']));
            }
            
            if (isset($attribute_names) && is_array($attribute_names)) {
                $attribute_string = implode(', ', $attribute_names);
                $x .= ' ' . $attribute_string;
            }
        }
        
        $y = $this->products[$i]['qty'];
        $z = ($this->products[$i]['final_price'] > 0 ? $this->products[$i]['final_price'] : $this->products[$i]['price']);
        $t = $this->products[$i]['tax'];
        $m = ($this->products[$i]['model'] == '' && $attribute_customid != '' ? $attribute_customid : $this->products[$i]['model']);
        $x = str_replace("<br>", "", $x );
    
        $itemname = "$y x $x";
        $totalexvat = $z * $y;
        $totalcost = (zen_add_tax($z, $t) * $y) + zen_add_tax($this->products[$i]['onetime_charges'], $t);
    
        $thistax = zen_calculate_tax($z, $t);
        $pwt = $z + $thistax;
        // $totaltax += zen_calculate_tax($z, $t) * $this->products[$i]['qty'];
        
        $z = number_format($z, 2, '.', '');
        $totalcost = number_format($totalcost, 2, '.', '');
        $pwt = number_format($pwt, 2, '.', '');
        // $totaltax = number_format($totaltax, 2, '.', '');
        $totalexvat = number_format($totalexvat, 2, '.', '');
        $t = $t . "%";
        // $total += $totalcost;
        $lines[$i] = "$itemname|$m|$t|$pwt|$totalcost";

    Default Re: Stock by Attribute v4.0 for Zen Cart 1.5.1+

    This post picks up following the discussion of "How to control extra_cart_actions file loading order" in the General Questions forum.

    The offer for mc... to add a notifier in the includes/extra_cart_actions/stock_by_attributes.php file would most likely solve my problem, but I'm not sure it's the best solution. If a notifier is added, it should be at the start of the file.

    I need to bring up a form and process the customer's responses to the form when a certain product with attributes is added to the shopping cart. So my extra_cart_actions file detects the product being added to the cart, saves the $_POST variables (because $_POST data is lost on redirect), and redirects to files that display the form and when the form is submitted, processes the responses. For reasons that escape me at the moment, the $_POST variables are not restored until the extra_cart_actions file is executed again later in the add product to cart process. When I developed this code, SBA did not have an extra_cart_action file, so the missing $_POST data was not missed by other extra_cart_actions files. But now, SBA has a file there, and it runs before my file, and it doesn't like missing $_POST data. I get a undefined index products_id notice on or about lines 372, 492, and 513.

    So while a notifier in SBA could trigger an observer that restores the $_POST data if not present, I think a better solution is to try and display the form, process the results, and restore $_POST (if necessary) all at once, instead of over two cycles through extra_cart_actions. I'm not sure I can accomplish that but that's what I'm going to try.
