Template global variables

For convenience Plone defines a couple of global variables often used in templates.

• {ref}backend-global-utils-portal-state-label
• {ref}backend-global-utils-context-state-label
• {ref}backend-global-utils-plone-view-label
• {ref}icons <classic-ui-icons-icon-resolver-label>
• lang
• {ref}classic-ui-templates-global-variables-portal-url-label
• {ref}classic-ui-templates-global-variables-check-permissions
• ajax_include_head
• isAnon

(classic-ui-templates-global-variables-portal-url-label)=

portal_url

portal_url will return the portal URL. It can be used as follows:

<a href="${portal_url}/@@overview-controlpanel>Overview Controlpanel</a>

It is basically a short cut for:

<div tal:define="portal_url python: portal_state.portal_url()">
  <a href="${portal_url}/@@overview-controlpanel">Overview Controlpanel</a>
</div>

(classic-ui-templates-global-variables-check-permissions)=

checkPermission

checkPermission will return the checkPermission method from portal_membership tool.

It can be used as follows to check for user permissions in templates:

<div tal:condition="python: checkPermission('Modify portal content', context)">
  <span tal:omit-tag="">
    You see this page because you have permission to edit this.
  </span>
</div>
