Add option to Magento system admin

I would like to add a textbox to the Header block located inside System>Config>Design>Header, the location in the image below.

location of input box

I know this has to be done in xml, but I am not sure where. Also how would I display that in an phtml file?

First add a field in system.xml file which is located in

app/code/core/Mage/Page/etc/system.xml,under header section

<header translate="label">
    ..........
        <welcome_massage translate="label">
            <label>Welcome Massage</label>
            <frontend_type>text</frontend_type>
            <sort_order>35</sort_order>
            <show_in_default>1</show_in_default>
            <show_in_website>1</show_in_website>
            <show_in_store>1</show_in_store>
        </welcome_massage>
    </fields>
</header>

Then add a method in header block , app/code/core/Mage/Page/Block/Html/Header.php

public function getWelcomeMassage()
{
    return $this->_data['welcome_massage'] = Mage::getStoreConfig('design/header/welcome_massage') ;
}

Last call this method in header.phtml file, like that 

<?php echo $this->getWelcomeMassage() ?>

Note : You see that I have code in core files. You should rewrite the core files.

In code/core/Mage/Page/etc/system.xml you will find the configuration that Magento reads to show those fields, for example the "Small Logo Image src" is a field called logo_src_small. The needed is a module that will tell Magento about:

  1. The extra field in the admin panel under header.

    <config>
    <sections>
        <design>
            <groups>
            <header>
            <fields>
            <new_field translate="label">
              <label>New Field</label>
              <frontend_type>text</frontend_type>
              <sort_order>1</sort_order>
              <show_in_default>1</show_in_default>
              <show_in_website>1</show_in_website>
              <show_in_store>1</show_in_store>
            </new_field>
            </fields>
            </header>
            </groups>
        </design>
    </section>
</config>

  2. Rewrite the block class code/core/Mage/Page/Block/Html/Header.php so you can add the method that will expose the new field.

  3. In the app/design/frontend/{Package}/{Theme}/template/page/html/header.phtml you can easily call $this->getNewField() where getNewField() is the method you have in the class we overridden in point 2.
