PHP - Show Number Of Products Per Page.

Hi,

I have a trouble figuring out how to properly convert a list of product data from XML into CSV format.

My source is a XML file containing a list of products with attributes like color, size, material etc. with the following structu
Code: [Select]
    <?xml version="1.0" encoding="utf-8" ?>
<store>
        <products>
            <product>
                <name>T-Shirt</name>
                <price>19.00</price>
                <attributes>
                    <attribute>
                        <name>Color</name>
                        <options>

                                <name>White</name>
                                <price>0.00</price>

                    </attribute>
                    <attribute>
                        <name>Material</name>
                        <options>
                            <option>
                                <name>Cotton</name>
                                <price>10.00</price>
                            </option>
                            <option>
                                <name>Polyester</name>
                                <price>0.00</price>
                            </option>
                        </options>
                    </attribute>
                </attributes>
            </product>
            <product>
                <name>Earrings</name>
                <price>29.00</price>
            </product>
        </products>
    </store>

Each product has a number of elements like name, price etc. but also a random number of attributes (like color, size, material etc.) that also have a random number of options.
Each option can affect the price of the product, so ordering a XS sized t-shirt can be cheaper than ordering a XL sized t-shirt.

I would like to end up with a CSV representing one attribute combination on each line.

In my example that would result in 3 colors x 5 sizes = 15 lines for the T-Shirt , 2 colors x 3 sizes x 2 materials = 12 lines for the Sweatshirt and 1 line for the Earrings without any attributes:
Code: [Select]
        name,price,color,size,material
T-Shirt,14.00,White,XS,
T-Shirt,14.00,Black,XS,
T-Shirt,14.00,Blue,XS,
T-Shirt,14.00,White,S,
T-Shirt,14.00,Black,S,
T-Shirt,14.00,Blue,S,
T-Shirt,19.00,White,M,
T-Shirt,19.00,Black,M,
T-Shirt,19.00,Blue,M,
T-Shirt,19.00,White,L,
T-Shirt,19.00,Black,L,
T-Shirt,19.00,Blue,L,
T-Shirt,24.00,White,XL,
T-Shirt,24.00,Black,XL,
T-Shirt,24.00,Blue,XL,
    Sweatshirt,49.00,White,XS,Cotton
Sweatshirt,49.00,Black,XS,Cotton
Sweatshirt,59.00,White,M,Cotton
Sweatshirt,69.00,Black,M,Cotton
Sweatshirt,69.00,White,XL,Cotton
Sweatshirt,69.00,Black,XL,Cotton
Sweatshirt,39.00,White,XS,Polyester
Sweatshirt,39.00,Black,XS,Polyester
Sweatshirt,49.00,White,M,Polyester
Sweatshirt,49.00,Black,M,Polyester
Sweatshirt,59.00,White,XL,Polyester
Sweatshirt,59.00,Black,XL,Polyester
Earrings,29.00,,,
   
I already managed to generate the CSV Output for simple products like the Earrings and products with just one attribute, but am struggling to come up with a way to generate all possible product attribute combinations for products with more than one attribute.

My miserable attempts at this so far have produced following code:

Code: [Select]
    <?php
    mb_internal_encoding("UTF-8");
    header('Content-Type: text/html; charset=utf-8');

    $source = "example.xml";

    $header_attributes = array();
    foreach ($xml->products->product as $product) {
        if(isset($product->attributes)) {
            foreach($product->attributes->attribute as $attribute) {
                array_push($header_attributes, $attribute->name);
            }
        }
    }
    $header_attributes = array_unique($header_attributes);

    $csvheader = array(
        'name','price' // these exist for all products, could also include weight, image, description, special price etc...

        if($simple == 1) { // if product is a simple product with no attributes
            $output=array();
            array_push($output,(string)$product->name);
            array_push($output,(string)$product->price);
            for($i = $static_csvheadercount + $attribute_position; $i < count($csvheader); $i++) {

        }
        else { // is a configurable product with attributes
            $json = json_encode($product->attributes);
            $attributes = json_decode($json, TRUE);
            $attributes_number = count($product->attributes->attribute);
            if($attributes_number > 1) { // if product has more than 1 attributes so we have to generate each attribute combination
                //
                // I'm trying to figure out what should happen here
                //
            }
            else { // if product has only one attribute
                $attributename =  (string)$product->attributes->attribute->name;
                $attribute_position = array_search($attributename, $header_attributes);
                $options_number = count($product->attributes->options->option);
                $pos = 1;
                foreach($attributes['attribute']['options']['option'] as $option) { 
                    $output=array();
                    array_push($output,(string)$product->name);
                    array_push($output,(string)$product->price);
                    for($i = $static_csvheadercount - 1; $i < ($static_csvheadercount + $attribute_position); $i++) {
                        array_push($output, '');
                    }

                    $output[$static_csvheadercount + $attribute_position] = $option['name'];
                    for($i = $static_csvheadercount + $attribute_position; $i < count($csvheader) - 1 ; $i++) {
                        array_push($output, '');
                    }
                    fputcsv($fp, $output);
                    $pos++;
                }
                $output=array();
                array_push($output,(string)$product->name);
                array_push($output,(string)$product->price);
                for($i = $static_csvheadercount; $i < count($csvheader); $i++) {
                    array_push($output, '');
                }
                fputcsv($fp, $output);
            }
        }
    }

    ?>
      
I've been stuck at this problem for hours unable to figure out a solution.

Can someone give a few tips or pointer how to achieve the output for products with multiple attributes?

   

Hi,

I have been working on an eCommerce platform for the last few months. Its almost complete but I need to do one thing and thats to only display sub categories if products exist in them.

This is the site craftgo.me (development site),

and this is how the categories are produced for a category page. ie. http://www.craftgo.me/category.php?cat_id=96

Code: [Select]
if($_GET['cat_id']) {
$parents_id = $_GET['cat_id'];
$cat_num_rows_sql = "SELECT category_id, parent_id FROM mccategories WHERE parent_id = '$parents_id'";
$cat_num_rows_result = mysql_query($cat_num_rows_sql);
$cat_row_count = mysql_num_rows($cat_num_rows_result);

if($cat_row_count == '0'){
$current_cat_parent_sql = "SELECT parent_id FROM mccategories WHERE category_id = '$cat_id'";
$current_cat_parent_result = mysql_query($current_cat_parent_sql);
$cat_parent_row = mysql_fetch_array($current_cat_parent_result);
$parent_id = $cat_parent_row['parent_id'];
} else {
$parent_id = $_GET['cat_id'];
}
}



$catsql = "SELECT category_id, category_name FROM mccategories WHERE cat_showing = '0' AND parent_id = '$parent_id' ORDER BY category_name";
$catresult = mysql_query($catsql);
while($catrow = mysql_fetch_array($catresult)) {

$category_id = $catrow['category_id'];
$cat_name = $catrow['category_name'];

echo '<li><a href="category.php?cat_id=' . $category_id . '">' . $cat_name . '</a></li>';
}

In the mcproducts table the category id for each product is under 'product_category'


Im not even sure where to start to make this work, but if anyone could give me a pointer, that would be super.

Many thanks
Eoin

ok, I can't seem to figure out how to go about this.  I have a form where pics can be uploaded with certain id's which will tell them where they are placed, in apDiv2-9.  the main id is how this is going to be identified.   I would like it also so that once there are 8 products, a new page will begin, starting with apDiv10-18(I need the 2-9 to automatically change to 10-18, so like it would be if results are greatehr than 8, then apdiv will add 8 to the number part of it).  I would like it to pull the image link from the database in the tag $image which will have to be pulled according to the apDiv#.  how would I do this?  does this make sense?  this is extremely hard to explain.  this is not the code that posts, this is the code that displays  here is code:
Code: [Select]
<?php 
include_once "connect_to_mysql_1.php";
$sql = mysql_query("SELECT * FROM products");
while($row = mysql_fetch_array($sql)){

$image = $row['link'];

}

/* ~~ These are the columns for the layout. ~~

1) Padding is only placed on the top and/or bottom of the divs. The elements within these divs have padding on their sides. This saves you from any "box model math". Keep in mind, if you add any side padding or border to the div itself, it will be added to the width you define to create the *total* width. You may also choose to remove the padding on the element in the div and place a second div within it with no width and the padding necessary for your design. You may also choose to remove the padding on the element in the div and place a second div within it with no width and the padding necessary for your design.

2) No margin has been given to the columns since they are all floated. If you must add margin, avoid placing it on the side you're floating toward (for example: a right margin on a div set to float right). Many times, padding can be used instead. For divs where this rule must be broken, you should add a "display:inline" declaration to the div's rule to tame a bug where some versions of Internet Explorer double the margin.

3) Since classes can be used multiple times in a document (and an element can also have multiple classes applied), the columns have been assigned class names instead of IDs. For example, two sidebar divs could be stacked if necessary. These can very easily be changed to IDs if that's your preference, as long as you'll only be using them once per document.

4) If you prefer your nav on the right instead of the left, simply float these columns the opposite direction (all right instead of all left) and they'll render in reverse order. There's no need to move the divs around in the HTML source.

I need to disable a query on the products page. The URL is www.myjabberbox.com
If you goto the products page, you'll see when you hover over one of the three products, you can
click it to take you to another page of that product. I want to disable that. I thought the code that
I'd need to modify would be under the products-page.php file but I can't seem to find the code.
Notice also when you hover over the products, a mouseover color of black happens around the image/text
frame, I'd like to keep that, just disable the linking...

Thanks

Like the title says. I have 4 of the same number in my database, but I only want my website to display one of the 4.

How can I do something like this?
