TYPO3 Custom Element colorpicker - php

Question

I'm new to TYPO3 (first project) and I have some understanding issues of the creation of a custom element with a colorpicker. In this project I already have created a few elements but I only use predetermined fields for the backend input. For the element I need next I need the user to choose a color. I haven't found a fitting existing element. My setup that doesn't work is in the TCA/Overrides/tt_content.php file and looks like this.
$GLOBALS['TCA']['tt_content']['item_0']=array();
$GLOBALS['TCA']['tt_content']['item_0']['label']='Color';
$GLOBALS['TCA']['tt_content']['item_0']['config']=array();
$GLOBALS['TCA']['tt_content']['item_0']['config']['type']='input';
$GLOBALS['TCA']['tt_content']['item_0']['config']['renderType']='colorpicker';
$GLOBALS['TCA']['tt_content']['item_0']['config']['size']=10;
$GLOBALS['TCA']['tt_content']['types']['wo_mitem'] = array(
'showitem' => '--palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.general;general,
header;Title,
subheader;Background,
header_link;Target,
item_0;Color,
bodytext;Text;;richtext:rte_transform[flag=rte_enabled|mode=ts_css]
');
The item_0 was a try to create a colorpicker but it doesn't seem to work. Do I need something different in a different file? The first few lines I added to define my field. Is there a better way to do this?
All other files in my custom extension work (since all other custom elements work fine). The only difference is, as said, the need of a way to choose a color in the new one.
Just for a clearer look here the other files
setup.txt:
lib.contentElement {
templateRootPaths {
100 = EXT:wostyle/Resources/Private/Template
}
}
tt_content {
wo_mitem < lib.contentElement
wo_mitem {
templateName = MItem
}
}
tt_content.php
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPlugin(
array(
'WO_Item (ItemBox, Text only)',
'wo_mitem',
'content-image'
),
'CType',
'wostyle'
);
$GLOBALS['TCA']['tt_content']['item_0']=array();
$GLOBALS['TCA']['tt_content']['item_0']['label']='Farbe';
$GLOBALS['TCA']['tt_content']['item_0']['config']=array();
$GLOBALS['TCA']['tt_content']['item_0']['config']['type']='input';
$GLOBALS['TCA']['tt_content']['item_0']['config']['renderType']='colorpicker';
$GLOBALS['TCA']['tt_content']['item_0']['config']['size']=10;
$GLOBALS['TCA']['tt_content']['types']['wo_mitem'] = array(
'showitem' => '--palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.general;general,
header;Bezeichnung,
subheader;Chemische Bezeichnung,
header_link;Zielseite,
item_0;Farbe,
bodytext;Text;;richtext:rte_transform[flag=rte_enabled|mode=ts_css]
');
typo.ts
mod.wizards.newContentElement.wizardItems.wo_extra {
header = WO Elemente
after = common
elements {
wo_mitem {
iconIdentifier = content-image
title = WO_Item (ItemBox, Text only)
description = Ein Produktfeld mit Text
tt_content_defValues {
CType = wo_mitem
}
}
}
show := addToList(wo_mitem)
}
MItem.html
<div class="item-text">

Answer 1

I did not check your whole code but I have a working color-picker on a field ...
you're close but an error that pops up right away is that your item should be placed under ['columns'] ...
$GLOBALS['TCA']['tt_content']['columns']['item_0']=array();
next you are missing the refference to the wizard !! (you should adopt the annotation with square brackets which shows much more the structure)
this should be stored in Configuration/TCA/Overrides/tt_content.php: (when you override existing fields, otherwise you have a dedicated code for the element)
<?php
/***************
* Modify the tt_content TCA
*/
$tca = [
'columns' => [
'item_0' => [
'label' => 'Color',
'config' => [
'type' => 'input',
'size' => 10,
'eval' => 'trim',
'default' => '#ffffff',
'wizards' => [
'colorChoice' => [
'type' => 'colorbox',
'title' => 'LLL:EXT:lang/locallang_wizards:colorpicker_title',
'module' => [
'name' => 'wizard_colorpicker'
],
'dim' => '20x20',
'JSopenParams' => 'height=600,width=380,status=0,menubar=0,scrollbars=1',
],
],
],
],
],
];
$GLOBALS['TCA']['tt_content'] = array_replace_recursive($GLOBALS['TCA']['tt_content'], $tca);

Answer 2

With the help of webMan and some internet searches I could adopt my code a little.
I added the file "ext_tables.sql" with the content
CREATE TABLE tt_content (
item_0 varchar(10) DEFAULT '' NOT NULL,
);
And changed the tt_content.php in TCA/Overrides to:
$temporaryColumns = Array(
"item_0" => Array(
'label' => 'Color',
'config' => Array(
'type' => 'input',
'renderType' => 'colorpicker',
'size' => 10
)
)
);
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTCAcolumns('tt_content',$temporaryColumns);
$GLOBALS['TCA']['tt_content']['types']['wo_mitem'] = array(
'showitem' => '--palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.general;general,
header;Bezeichnung,
subheader;Chemische Bezeichnung,
header_link;Zielseite,
item_0;Farbe,
bodytext;Text;;richtext:rte_transform[flag=rte_enabled|mode=ts_css]
');
There are still a view things missing in compare to webMans code but at least this is the first working version I have so i figured i show it since my question is answered:).
