## could not determine type of argument "section" of the render-method in ViewHelper "Tx_Fluid_ViewHelpers_RenderViewHelper" {#could-not-determine-type-of-argument-section-of-the-render-method-in-viewhelper-tx-fluid-viewhelpers-renderviewhelper}

> [!NOTE]
> The information on this page is outdated and no longer applies to TYPO3
> >= 10.0 (and was deprecated in earlier versions). Arguments to a
> ViewHelper are registered with `registerArgument()` and no longer
> passed as arguments to the render function. See Changelog
> [Deprecation: #81213 - Render method arguments on ViewHelpers deprecated](https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/9.0/Deprecation-81213-RenderMethodArgumentOnViewHelpersDeprecated.html)

This exception is thrown if the PHPDoc `@param` entry in a Fluid ViewHelper
is incorrect or if you are using a PHP optimizer with opcode caching
like the builtin [Opcache](https://www.php.net/manual/en/opcache.configuration.php)
and have disabled the storing of PHPDoc blocks. Fluid ViewHelpers needed the
PHPDoc entries to determine the data type (in older TYPO3 versions).

```text
#1242292003: could not determine type of argument "section" of the
  render-method in ViewHelper "Tx_Fluid_ViewHelpers_RenderViewHelper".
Either the methods docComment is invalid or some PHP optimizer strips off
  comments.
```

**Solution:**

1.  check PHPDoc block, it must start with \*\* (two stars).
1.  attribute must be mentioned as `@param type $variableName`.
1.  alternatively use `$this->registerArgument()` in `initializeArguments()`
    method.
1.  If using [eAccelerator](http://eaccelerator.net/): compile eAccelerator with option
    "--with-eaccelerator-doc-comment-inclusion": "If you want
    eAccelerator to retain doc-comments in internal php structures"
    (eAccelerator help)
1.  Use another PHP optimizer. I use xCache on Debian Squeeze which seems
    to work fine.
1.  using the opcode cache of modern PHP versions, you can set
    opcache.save_comments=1 (and opcache.load_comments=1 in PHP < 7.0).
