Flexform in typo3 7.6.2 not working

Question

I have created a extension using extension builder in typo3 7.6.2 version. Now I would like to add flexform to extension 'Products' for detail page PID. But I tried my best to integrate flexform but it did not work.

Here is my code -

In ext_tables.php -

  \TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerPlugin(
        'Wxproducts.' . $_EXTKEY,
        'Wxproducts',
        'Products'
    );

// flexform integration 
$pluginSignature = str_replace('_','','Wxproducts'.$_EXTKEY) . '_products';
$TCA['tt_content']['types']['list']['subtypes_addlist'][$pluginSignature] = 'pi_flexform';
t3lib_extMgm::addPiFlexFormValue($pluginSignature, 'FILE:EXT:' . $_EXTKEY . '/Configuration/FlexForms/flexform_products.xml');

In Configuration/FlexForms/flexform_products.php -

<T3DataStructure>
 <sheets>
  <sDEF>
   <ROOT>
     <TCEforms>
      <sheetTitle>Function</sheetTitle>
     </TCEforms>
     <type>array</type>
     <el>
      <switchableControllerActions>
       <TCEforms>
         <label>Select function</label>
         <config>
          <type>select</type>
          <items>

            <numIndex index="0">
             <numIndex index="0">List</numIndex>
             <numIndex index="1">Products->list</numIndex>
            </numIndex>

            <numIndex index="1">
             <numIndex index="0">Detail</numIndex>
             <numIndex index="1">Products->show</numIndex>
            </numIndex>

           </items>
         </config>
       </TCEforms>
      </switchableControllerActions>
     </el>
   </ROOT>
  </sDEF>
 </sheets>
</T3DataStructure>

Its not working. I am unable to figure out whats the problem. Any idea!

Thanks in Advance!

Might you did mistake in pluginSignature, try below code might helps you.

Working with v7.6.3

- ext_tables.php

/*** FlexForm ***/
$extensionName = \TYPO3\CMS\Core\Utility\GeneralUtility::underscoredToUpperCamelCase($_EXTKEY);
$pluginSignature = strtolower($extensionName) . '_products'; 

$TCA['tt_content']['types']['list']['subtypes_addlist'][$pluginSignature] = 'pi_flexform';
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPiFlexFormValue($pluginSignature, 'FILE:EXT:'.$_EXTKEY.'/Configuration/FlexForms/FlexForm.xml');
/*** FlexForm ***/

-FlexForm.xml

Answer 2

Your $pluginSignature variable seems to be wrong, it has the vendor name on it. Try the following code:

$extensionName = strtolower(\TYPO3\CMS\Core\Utility\GeneralUtility::underscoredToUpperCamelCase($_EXTKEY));
$pluginSignature = $extensionName.'_products';    

Here's an example taken from TYPO3 Extbase book:

$pluginSignature = 'simpleblog_bloglisting';

simpleblog is the extension key, and bloglisting is the plugin name.

Answer 3

In a file ext_tables.php on line:

t3lib_extMgm::addPiFlexFormValue

try use this:

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPiFlexFormValue
