Globals store content that is available globally throughout your templates. They're a convenient way to make non-Entry content easily editable via the Control Panel.
Craft organizes Globals into Global Sets. Each Global Set has its own field layout using any of the existing fields or new fields.
To create a Global Set, go to Settings → Globals.
If you have at least one Global Set, Craft will add a new “Globals” item added to the Control Panel primary navigation. Clicking on this will take you to a page that lists all of your Global Sets in a sidebar, as well as all of the fields associated with the selected Global Set in the main content area.
{tip} Unlike entries, Global Sets don’t have the Live Preview feature, since they aren’t associated with any one particular URL.
You can access your Global Sets from any template via their handles.
If you have a Global Set with the handle companyInfo and it has a field with the handle yearEstablished, you can access that field anywhere using this code:
{{ companyInfo.yearEstablished }}For additional Global Set properties you can ise besides your custom fields see {entry:templating/globalsetmodel:link} for a full reference.
If you run multiple sites with Craft, Global Sets are available in all sites. However, you can set the values in those sets on a per site basis, even leaving some fields blank, if desired.
To toggle between sites while viewing Global Sets, use the drop-down menu at the top left of the Global Sets page in the Control Panel.
