The following are instructions regarding the use of multiple attributes with Market. Please send any questions to the Market Theme forums.


Using Market with Multiple Attributes:

If you have not made any significant changes to your Market 3 install, download the Market 3 Multiple Attributes theme package from the Download Center. This compressed file has done all the work for you and includes the Market Product Manager 1.5 beta which allows you to easily use Multiple Attributes with your products. If you have made customizations to your theme and do not wish to overwrite, there are some quick instructions below to get multiple attributes working for you.

  1. First things first. A new version of Market Product Manager version 1.5 is listed in the Download Center. This version has additional features which will allow you easily add attributes and pricing to your products. Download, unzip, and upload the "marketproductmanager1.5" folder to your .../wp-content/plugins/ directory. After uploading you will need to login to your Wordpress administration area, and activate this plugin.
  2. Now for the changes necessary to make the Market theme shopping cart work with it. Start by opening the "header.php" file in your theme. (You can do this through the "Design Theme Editor" menu tab in your WP administration area.) You'll notice a big chunk of javascript that is used by the Market Shopping Cart. Copy and paste the following additional javascript right before the closing "</head>" tag. (If for some reason copying and pasting from this screen doesn't work, copy and paste from the javascript source text file):

  3. Next, open your "single.php" file. Scroll down until you find for the tag that says: <div class="buy">. Replace everything from and including this opening <div class"buy> tag, all the way to the closing </div> tag.
    (You'll find the closing "</div>" tag 2 lines below the text reading "<!--End Vcart Code-->".

  4. With that complete, you are now ready to utlize multiple attributes. This has been tested and both the "buy now" and "add to cart" functions appeared to be working just fine. If you discover and error, please point it out in the forums.

Add more multiple attributes:

Adding more multiple attributes can be done. I will not assist each and every case, so it is up to you to make the required changes. I'll outline how to add additional multiple attribute fields below, but you must make the changes for yourself. The default setup of multiple attributes has just one drop down, can be used to specify whatever you may like and a matching price. You may want two, three, or even more options and dropdowns, for example the colors, sizes, and styles of piece of clothing. The color could set the base price, the size could increase it by a few bucks, and the style could increase it by a few more. There are an unlimited amount of ways you could put the multiple attributes to work for you. Read this guide and view the source of single.php to get a better idea of how to add the actual fields themselves.

After adding the fields themselves to single.php, you'll probably want to be able to control these items via the Market Product Manager. Adding them is not that hard.

  1. Open up marketproductmanager.php found in the MPM plugin folder. Lines 89-104 are all lines calling for custom fields. You'll notice the options1-options3 and sprices1-3. Follow this base and add as many additional custom fields as you may want. These custom fields will store your attribute data to be selected in the dropdowns on your single.php file. Keep the names of your custom fields in mind, as we have a few other places in this file to edit. An example of an added line would look like this:
    2. mycustomattribut1 = get_post_meta($post->ID, 'mycustomattribute1', $single = true);
  2. Now let's continue down the file. You'll find some h2 tags wrapped around the words "Multiple Attributes". You'll see 3 different chunks of "postbox" code. Simply repeat this as many times as you want based how many multiple attributes you plan to have. At the time being the code isn't very efficient, so if you have one menu with 3 choices, one menu with 4, and one with 2, you'll need 9 multiple attribute boxes all together.
  3. The most important thing to remember when repasting the "postbox" div is to change the name and id and the call to the custom field in the input lines of each postbox bit. < input type="text" name="mycustomattribut" id=" mycustomattribut" value="< ?php echo $ mycustomattribut; ? >" scrolling="auto" cols="30" rows="4" tabindex="10" >
  4. When that's all done, travel down to lines 303-321. Notice the options1-3 and sprices 1-3 again? Follow the same pattern to add all the custom fields you just used in your additional multiple attribute boxes. Place them in the order their post bit boxes appear!
  5. One last bit. A few lines under those your going to see lines like this: delete_post_meta($id, 'options1');. Once again, follow the format to add lines for your custom fields, placing them in the same order as they appear in the postbox bit. Same thing for a few lines under that where you'll add post meta data by following the format already there in the code for you.
  6. Once this is done your plugin with your multiple fields should be functioning. If it is not, try posting in the forums. I will not assist on a case by case basis, but I will look over it if I get a chance.

Adding Size and or Color List back to the forum:

If you wish to use the size and or color list dropdowns without price differences for each, Add whichever code below you may need above the following < tr >< td >Image Size:< /td > in both the add to cart button and the buy now button (it will appear twice in single.php)

          <?php if (!empty($size)){

            echo "

              <td><input type=\"hidden\" name=\"on0\" value=\"Size\"/>

                Size:</td>

              <td><select name=\"os0\" class=\"field\" > 

                  

            <option value=\"$sizelist[0]\">$sizelist[0]</option>";

                  

            if (isset($sizelist[1])) { echo "<option value=\"$sizelist[1]\">$sizelist[1]</option>"; }

            if (isset($sizelist[2])) { echo "<option value=\"$sizelist[2]\">$sizelist[2]</option>"; }

            if (isset($sizelist[3])) { echo "<option value=\"$sizelist[3]\">$sizelist[3]</option>"; }

            if (isset($sizelist[4])) { echo "<option value=\"$sizelist[4]\">$sizelist[4]</option>"; }

            if (isset($sizelist[5])) { echo "<option value=\"$sizelist[5]\">$sizelist[5]</option>"; }

            if (isset($sizelist[6])) { echo "<option value=\"$sizelist[6]\">$sizelist[6]</option>"; }

            if (isset($sizelist[7])) { echo "<option value=\"$sizelist[7]\">$sizelist[7]</option>"; }

            if (isset($sizelist[8])) { echo "<option value=\"$sizelist[8]\">$sizelist[8]</option>"; }

            if (isset($sizelist[9])) { echo "<option value=\"$sizelist[9]\">$sizelist[9]</option>"; }

            if (isset($sizelist[10])) { echo "<option value=\"$sizelist[10]\">$sizelist[10]</option>"; }

             echo "   </select>

              </td>"; } ?>
        </tr>

Color List

<tr>
          <td><?php if (!empty($color)){

            echo "<input type=\"hidden\" name=\"on1\" value=\"Color\"/>

                Color:</td>

              <td><select name=\"os1\" class=\"field\">

              

            <option value=\"$colorlist[0]\">$colorlist[0]</option>";

            

            if (isset($colorlist[1])) { echo "<option value=\"$colorlist[1]\">$colorlist[1]</option>"; }

            if (isset($colorlist[2])) { echo "<option value=\"$colorlist[2]\">$colorlist[2]</option>"; }

            if (isset($colorlist[3])) { echo "<option value=\"$colorlist[3]\">$colorlist[3]</option>"; }

            if (isset($colorlist[4])) { echo "<option value=\"$colorlist[4]\">$colorlist[4]</option>"; }

            if (isset($colorlist[5])) { echo "<option value=\"$colorlist[5]\">$colorlist[5]</option>"; }

            if (isset($colorlist[6])) { echo "<option value=\"$colorlist[6]\">$colorlist[6]</option>"; }

            if (isset($colorlist[7])) { echo "<option value=\"$colorlist[7]\">$colorlist[7]</option>"; }

            if (isset($colorlist[8])) { echo "<option value=\"$colorlist[8]\">$colorlist[8]</option>"; }

            if (isset($colorlist[9])) { echo "<option value=\"$colorlist[9]\">$colorlist[9]</option>"; }

            if (isset($colorlist[10])) { echo "<option value=\"$colorlist[10]\">$colorlist[10]</option>"; }

              echo "

                </select>

              </td>"; } ?>
        </tr>
