Okay this is what I did, and it's really not that hard if you know a little about PHP coding. I know only a little, but I do know how to add mods if I have too.
Alright I went to Admin --> Packages --> Browse Packages
From there I found SMF Shop (although notice it's not installed) and clicked on List Files, it will take you to a page with a list of ALL the files that the SMF Shop has. From there I clicked on the link install_SMF1_1RC2.xml (you may have 1RC3, if so click on that). From there it will tell you which files you need to edit, for example it will look like this:
<file name="$boarddir/index.php">
<operation>
<search position="before"><![CDATA[
'.xml' => array('News.php', 'ShowXmlFeed'),
]]></search>
<add><![CDATA[
//Begin Shop MOD 0.2 code
'shop' => array('shop/Shop.php', 'Shop'),
'shop_general' => array('shop/ShopAdmin.php', 'ShopGeneral'),
'shop_inventory' => array('shop/ShopAdmin.php', 'ShopInventory'),
'shop_items_add' => array('shop/ShopAdmin.php', 'ShopItemsAdd'),
'shop_items_edit' => array('shop/ShopAdmin.php', 'ShopItemsEdit'),
//Begin SMFShop MOD 2.0 (Build 8) code
'shop_restock' => array('shop/ShopAdmin.php', 'ShopRestock'),
//END SMFShop MOD code
'shop_usergroup' => array('shop/ShopAdmin.php', 'ShopUserGroup'),
//END SHOP MOD
]]></add>
</operation>
</file>
So, in this you will need to open your MAIN index.php that is located in your Forum Folder of your site (or if you're like me you have a back up of your forum on your computer and you can adjust things from there). I use WordPad OR Dreamweaver to work on PHP Coding, as they have a Find option and I use that a bit. To know what file to look for it will look like this:
<file name="$boarddir/index.php">
Notice it says file name? That's how you know, it also gives you where it's located, in this case it's located in your main Folder for your forum.
To know what code to look for you need to look for this:
<operation>
<search position="before"><![CDATA[
'.xml' => array('News.php', 'ShowXmlFeed'),
]]></search>
What's between the [CDATA[
CODE HERE ]] is what you will be looking for, and notice that it says search position and it says before, you will place the code BEFORE it. (If it says replace you replace it, if it says after you place the code after).
To know the code that you will be replacing, adding before or after you will need to look for this:
<add><![CDATA[
//Begin Shop MOD 0.2 code
'shop' => array('shop/Shop.php', 'Shop'),
'shop_general' => array('shop/ShopAdmin.php', 'ShopGeneral'),
'shop_inventory' => array('shop/ShopAdmin.php', 'ShopInventory'),
'shop_items_add' => array('shop/ShopAdmin.php', 'ShopItemsAdd'),
'shop_items_edit' => array('shop/ShopAdmin.php', 'ShopItemsEdit'),
//Begin SMFShop MOD 2.0 (Build 8) code
'shop_restock' => array('shop/ShopAdmin.php', 'ShopRestock'),
//END SMFShop MOD code
'shop_usergroup' => array('shop/ShopAdmin.php', 'ShopUserGroup'),
//END SHOP MOD
]]></add>
</operation>
I start coping from //Begin Shop MOD 0.2 code all the way to //END SHOP MOD, this is what's easy for me.
Once you're done with the editing of the file it will close it by this:
</file>
It will do this for EVERY file that needs to be edited. So PAY CLOSE ATTENTION!!
The only code that I had to do differently was this one:
<file name="$boarddir/Themes/default/ManageBoards.template.php">
<operation>
<search position="before"><![CDATA[<input type="checkbox" name="override_theme"', $context['board']['override_theme'] ? ' checked="checked"' : '', ' class="check" />
</td>
</tr>';]]></search>
<add><![CDATA[
//BEGIN SMFShop Shop MOD 1.3 (Build 6) code
loadLanguage("Shop");
echo ' <tr>
<td>
<b>', $txt['shop_count_points'], '</b><br />
', $txt['shop_count_points_msg'], '<br /><br />
</td>
<td valign="top" align="right">
<input type="checkbox" name="countMoney"', $context['board']['countMoney'] ? ' checked="checked"' : '', ' class="check" />
</td>
</tr>';
//END SHOP MOD
]]></add>
</operation>
</file>
<file name="$boarddir/Themes/default/Display.template.php">
<operation>
<search position="replace"><![CDATA[
// Show how many posts they have made.
echo '
', $txt[26], ': ', $message['member']['posts'], '<br />
<br />';
]]></search>
Instead of placing the code BEFORE, it should be AFTER.
The Shop will STILL read that it's not installed but it is
Other than that, that's all I had to do, but I do advise that you have already had Shop installed before doing this, if you haven't then you'll need to wait until Daniel can come out with a version that is working with SMF 1.1
I hope that this helps someone, I'm not very good at giving out instructions on how to do things; which is why I don't do tutorials
