// Define the field configuration $myFieldConfig = array( 'new_field' => array( 'exclude' => 1, 'label' => 'New Field', 'config' => array( 'type' => 'input', 'size' => 30, 'eval' => 'trim' ) ) ); // Add the field to all types of Content Elements t3lib_extMgm::addToAllTCAtypes( 'tt_content', 'new_field', '', 'after:bodytext' );In this example, the "tt_content" parameter specifies that we want to add the new field to all Content Elements. The "new_field" parameter specifies the name of the new field we want to add. The third parameter is empty, which means we want the new field to be added to all types of Content Elements. The last parameter is "after:bodytext", which specifies that we want the new field to be added after the "bodytext" field in the Content Elements. The t3lib_extMgm addToAllTCAtypes function is part of the TYPO3 core library, which means it is included by default in all TYPO3 installations.
