Cannot call controller action from top-level Fluid template

959 Views Asked by christian2222 At 27 April 2025 at 01:59

I have a self written TYPO3 extension (I used ext:extension_builder to create it)

My top-level TypoScript looks like this:

page = PAGE
page.10 = FLUIDTEMPLATE
page.10 {
    format = html
    file = EXT:cmsp/Resources/Private/Templates/User/Default.html
    partialRootPaths {
        10 = EXT:cmsp/Resources/Private/Partials/
    }
    layoutRootPaths {
        10 = EXT:cmsp/Resources/Private/Layouts/
    }
    templateRootPaths
        10 = EXT:cmsp/Resources/Private/Templates/
    }
    variables {
        content_main < styles.content.get
        content_main.select.where = colPos = 0
    }
}

I used a simple Fluid Styled Content template:

<f:link.action controller="user" action="search" class="btn btn-secondary">action link</f:link.action>

The search action is registered in ext_localconf.php:

\TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin(
    'SimpleParser.Cmsp',
    'Cmspfe',
     [
         'User' => 'list,search'
     ],
     // non-cacheable actions
     [
         'User' => 'list,search'
     ]
);

I have also a template Search.html:

<html xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers" data-namespace-typo3-fluid="true">
<f:layout name="Search" />

<f:section name="content">
    <h1>Search Template</h1>

    <f:flashMessages />

    <table  class="tx_cmsp" >
        <tr>
            <th> </th>
            <th> </th>
        </tr>
    </table>
     <form action="SearchConfim.php">
        Searchterm: <input type="text" name="sTerm"><br>
<input type="submit" value="Submit">
</form> 
</f:section>
</html>

The problem is that I cannot create or follow a link in the website frontend from top-level Default.html (FLUIDTEMPLATE object) to Search.html (Extbase controller template):

<f:link.action controller="user" action="search" class="btn btn-secondary">action link</f:link.action>

I just stay on Default.html all the time, even when I click an action link of my controller. I can create external links with

<f:link.external ... ></f:link.external>

The external link is working but I cannot use a link to access Search.html. Perhaps the problem is that I use a TypoScript which does not activate the controller (in a right way). But I'm happy if anyone can help me.

**Oliver Hader** · Answer 1

It seems that Default.html is the name of the top-level rendering template in FLUIDTEMPLATE. So, I assume that <f:link.action ... tag is placed in that file - at least the currently generated link seems to confirm it and looks like the following:

index.php?id=1
&tx__%5Baction%5D=search
&tx__%5Bcontroller%5D=User
&cHash=dffabf13e973c371d14fb2e34b23d1a0

It uses tx__ as prefix which actually should be something like tx_cmsp_cmspfe (the combination of your extension name and the corresponding plugin name to be used).

Brief explanation

Default.html template is outside of the Extbase scope and thus does not know about the current extension, controller and plugin that shall be used
usually links appear in templates of the same extension (e.g. in Resources/Private/Templates/List.html)
otherwise according scope has to be defined explicitly (like shown below)

Solution for placing link to Extbase plugin in top-level rendering template

This example can be used outside the Extbase scope on Default.html template for the current page layout - however, it explicitly has to use the correct Extbase plugin scope:

<f:link.action
    action="search"
    controller="User"
    pluginName="Cmspfe"
    extensionName="Cmsp"
    pageUid="4321"
    class="btn btn-secondary">

    action link
</f:link.action>

pageUid has to be adjusted and refers to the page the plugin is currently being used as content element
see https://fluidtypo3.org/viewhelpers/fluid/master/Link/ActionViewHelper.html as reference for links
see https://fluidtypo3.org/viewhelpers/fluid/master/FormViewHelper.html as reference for scoped <form> elements (which appeared in your code as well - pluginName, extensionName and pageUid are essential attributes in this scenario as well)

Your controller name is User with an uppercase U. Use the same name in your f:link.action, if the controller is not being changed you can even remove this parameter.
