apex:define

A template component that provides content for an <apex:insert> component defined in a Visualforce template page.

Use this component to get user input for a controller method that does not correspond to a field on an sObject. Only <apex:inputField> and <apex:outputField> can be used with sObject fields.

See also: <apex:composition>, <apex:insert>

Example

<!-- Page: composition -->
<!-- This page acts as the template. Create it first, then the page below.  -->	
<apex:page>
    <apex:outputText value="(template) This is before the header"/><br/>
    <apex:insert name="header"/><br/>
    <apex:outputText value="(template) This is between the header and body"/><br/>
    <apex:insert name="body"/>
</apex:page>
            
<!-- Page: page -->
<apex:page>
    <apex:composition template="composition">
        <apex:define name="header">(page) This is the header of mypage</apex:define>
        <apex:define name="body">(page) This is the body of mypage</apex:define>
    </apex:composition>
</apex:page>

The example above renders the following HTML:

(template) This is before the header<br/>
(page) This is the header of mypage<br/>
(template) This is between the header and body<br/>
(page) This is the body of mypage
