Building a TYPO3 extension in Extbase/Fluid

Using rich text on a textfield

Add RTE (Rich Text Editor) to textfield and display textfield as HTML in frontend

Option 1

Use the Extension Builder ››› set the respective properties to “Rich Text” instead of “Text”

Option 2 for TYPO3 8 LTS and later

Manually edit /typo3conf/ext/your_extension/Configuration/TCA/YourModelObject.php

just add 'enableRichtext' => true, to array columns['your_property']['config']

'config' => array(

        'type' => 'text',

        'enableRichtext' => true,
        'eval' => 'trim',
),
        'eval' => 'trim',
),

Option 2 for TYPO3 6.2 and 7

Manually edit /typo3conf/ext/your_extension/Configuration/TCA/YourModelObject.php

  1. in array 'types' change your_property to your_property;;;richtext::rte_transform[flag=rte_disabled|mode=ts_css]
  2. 
in same file change array 'columns' ››› add defaultExtras to columns[your_property] and change the array config ›››
'config' => array(

        'type' => 'text',

        'eval' => 'trim',

        'wizards' => array(

                'RTE' => array(

                        'icon' => 'wizard_rte2.gif',

                        'notNewRecords'=> 1,

                        'RTEonly' => 1,

                        'script' => 'wizard_rte.php',

                        'title' => 'LLL:EXT:cms/locallang_ttc.xlf:bodytext.W.RTE',

                        'type' => 'script'

                )
        )
),
'defaultExtras' => 'richtext[]:rte_transform[mode=ts_css]'
        )
),
'defaultExtras' => 'richtext[]:rte_transform[mode=ts_css]'

Additionally you’ll have to wrap the field in the fluid template like <f:format.html>{object.property}</f:format.html> otherwise all HTML tags entered by the RTE will be encoded with HTML entities and thus displayed as source code.
