TYPO3 TCA value as a variable on Fluid

Question

I have a base extension so i can version my website. That means i have not a controller or a repository on the extension. So what i want to do, is to create my own settings on existing elements. I was experimenting around with a text align values on the header content element.

Keep in mind, there is already a setting for this, but i am just experimenting.

I figured out how to add them and the values are saved on the database.

What i now want to do, is to take the values and add them as a class on FLUID. This is where i stuck. I can not get the values. Any idea how to do it?

After this guide How to enable header_position in TYPO3 7.6 i manage to get my code that far:

On the folder /Configuration/TCA/Overrides/tt_content.php

use TYPO3\CMS\Core\Utility\ExtensionManagementUtility;
ExtensionManagementUtility::addTCAcolumns('tt_content',[
'header_position_custom' => [
        'exclude' => 1,
        'label' => 'header position',
        'config' => [
                'type' => 'select',
                'renderType' => 'selectSingle',
                'items' => [
                        ['left', 'left'],
                        ['right', 'right'],
                        ['center', 'center']
                ]
        ]
]   
]);

ExtensionManagementUtility::addFieldsToPalette('tt_content', 'header', '--linebreak--,header_position_custom', 'after:header_layout');
ExtensionManagementUtility::addFieldsToPalette('tt_content', 'headers', '--linebreak--,header_position_custom', 'after:header_layout');

On the folder /Configuration/Typoscript/Constants/Base.typoscript

styles.templates.templateRootPath = EXT:my_website_base/Resources/Private/Extensions/Fluid_styled_content/Resources/Private/Templates/
styles.templates.partialRootPath = EXT:my_website_base/Resources/Private/Extensions/Fluid_styled_content/Resources/Private/Partials/
styles.templates.layoutRootPath = EXT:my_website_base/Resources/Private/Extensions/Fluid_styled_content/Resources/Private/Layouts/

On the /Resources/Private/Extensions/Fluid_styled_content/Resourcs/Private/Partials/Header.html

<h1 class="{positionClass} {header_position_custom} {data.header_position_custom} showed">
    <f:link.typolink parameter="{link}">{header}</f:link.typolink>
</h1>

I 've put the class showed just to make sure that i am reading the file from the path i gave on the constants

File ext_tables.php

TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addStaticFile($_EXTKEY,'Configuration/TypoScript', 'Website Base');

File ext_tables.sql

CREATE TABLE tt_content (
   header_position_custom varchar(255) DEFAULT '' NOT NULL,
);

With all these i get my selectbox where i wanted to be and i get the values on the database. That means that if i select the value "Center" in the selectbox, then it will be saved on the database. How can i get this value and use it as class on the FLUID?

Thanks in advance,

You will find your field in the data object.

For inspecting your fluid variables you can use the f:debug-VH:

<f:debug title="the data">{data}</f:debug>

for inspecting all (in the current context) available variables you can debug _all:

<f:debug title="all data">{_all}</f:debug>

Hint: use the title attribute to identify the output

and don't forget to write a get* and set* function for new fields!

i debugged the {data} variable and it came NULL. I should had written it on my question. What do you mean by get* and put*???? – Aristeidis Karavas May 23 '18 at 08:12
something should be there (try `{_all}`), otherwise your object can't be rendred at all. be sure to inherit from a base class and add getter and setter for your fields. – Bernd Wilke πφ May 23 '18 at 08:17
I think my object doesnt get rendered. That is what i get. http://prntscr.com/jlhkcm Where should i put my getters und setters? – Aristeidis Karavas May 23 '18 at 08:19
you can use the `ext:extension_builder` to build a prototype of an extension which adds just one field to an existing record (e.g. tt_content). see the declaratiosn and the inheritances. – Bernd Wilke πφ May 23 '18 at 08:20
Well, normally the getters und setters are written on the /Class/Domain/Model/File.php Since i do not use any Class at all, is there any other way? – Aristeidis Karavas May 23 '18 at 08:22
I don't find proof but there is an idea in my head of magic getter and setter for all fields of tt_content. So you might need a class only for the getter and setter. – Bernd Wilke πφ May 23 '18 at 08:30
