render¶
A ViewHelper to render a section, a partial, a specified section in a partial or a delegate ParsedTemplateInterface implementation.
Examples¶
Rendering partials¶
<f:render partial="SomePartial" arguments="{foo: someVariable}" />
Output:
the content of the partial "SomePartial". The content of the variable {someVariable} will be available in the partial as {foo}
Rendering sections¶
<f:section name="someSection">This is a section. {foo}</f:section>
<f:render section="someSection" arguments="{foo: someVariable}" />
Output:
the content of the section "someSection". The content of the variable {someVariable} will be available in the partial as {foo}
Rendering recursive sections¶
<f:section name="mySection">
<ul>
<f:for each="{myMenu}" as="menuItem">
<li>
{menuItem.text}
<f:if condition="{menuItem.subItems}">
<f:render section="mySection" arguments="{myMenu: menuItem.subItems}" />
</f:if>
</li>
</f:for>
</ul>
</f:section>
<f:render section="mySection" arguments="{myMenu: menu}" />
Output:
<ul>
<li>menu1
<ul>
<li>menu1a</li>
<li>menu1b</li>
</ul>
</li>
[...]
(depending on the value of {menu})
Passing all variables to a partial¶
<f:render partial="somePartial" arguments="{_all}" />
Output:
the content of the partial "somePartial".
Using the reserved keyword "_all", all available variables will be passed along to the partial
Rendering via a delegate ParsedTemplateInterface implementation w/ custom arguments¶
<f:render delegate="My\Special\ParsedTemplateImplementation" arguments="{_all}" />
This will output whichever output was generated by calling My\Special\ParsedTemplateImplementation->render()
with cloned RenderingContextInterface $renderingContext as only argument and content of arguments
assigned in VariableProvider of cloned context. Supports all other input arguments including
recursive rendering, contentAs argument, default value etc.
Note that while ParsedTemplateInterface supports returning a Layout name, this Layout will not
be respected when rendering using this method. Only the render()
method will be called!
