Magento - Add CMS Block to One Page - magento

Question

I have this code in a xml layout file:
<reference name="left">
<block type="blog/blog" name="left.blog.menu" before="-">
<action method="setTemplate" ifconfig="blog/menu/left">
<template>aw_blog/menu.phtml</template>
</action>
<block type="blog/tags" name="blog_tags" />
</block>
</reference>
I want to add a cms static block to the blog pages using this code:
<block type="cms/block" name="brand_list">
<action method="setBlockId"><block_id>brand_list</block_id></action>
</block>
If I add it in directly after this line:
<reference name="left">
It works but it is then displayed on every page. How can I get it to show only on the blog pages?
Thanks.
Edit: Here is the entire xml file:
<layout version="0.1.0">
<default>
<reference name="footer_links">
<block type="blog/blog" name="add.blog.footer">
<block type="blog/tags" name="blog_tags" />
<action method="addFooterLink" ifconfig="blog/menu/footer"></action>
</block>
</reference>
<reference name="right">
<block type="blog/blog" name="right.blog.menu" before="-">
<action method="setTemplate" ifconfig="blog/menu/right" ifvalue="1">

Answer 1

if it's going inside a section then it will be applied to all pages, you want to put the and its contents inside the sections (there'll be the listing page and individual post pages - the sections should already exist in the aw_blog.xml file

Answer 2

It appears on all pages, because you probably put the code in the section of the layout xml. Just put into a section named after the route where it should appear.
So try:
<blog>
<reference name="left">
<block type="cms/block" name="brand_list">
<action method="setBlockId"><block_id>brand_list</block_id></action>
</block>
</reference>
</blog>

Answer 3

Change XML inside folder theme/layout for example page.xml add something like this to header:
<block type="page/html_header" name="header" as="header">
<!-- ... some origin code ... -->
<block type="page/html" name="custom_block" as="flashHeader" template="customer/custom_header.phtml"/>
</block>
Create file customer/custom_header.phtml with your custom html code.
Inside template page/html/header.phtml you can add something like this:
$dataCurrentPage = $this->getHelper('cms/page')->getPage()->getData();
$page_id = (isset($dataCurrentPage['identifier'])) ? $dataCurrentPage['identifier'] : null;
if ($page_id == 'home' ) { echo this->getChildHtml('flashHeader') }
Flash banner will be show only on homepage.

Answer 4

You can definitely use the custom layout update to place your own static block on left without any coding.
You need to create a static block and then put its reference into custom layout update
<reference name="left">
<block type="cms/block" name="my_left_block" before="-">
<action method="setBlockId"><block_id>my_left_block</block_id></action>
</block>
