TYPO3 Gridelements render FAL Image using Fluidtemplate - typo3

Question

I'm using TYPO3 8.7 and the latest extension gridelements (8.2.3). Now I want to show/render an image in my FLUIDTEMPLATE.. - but I don't know how?!?
Here's my TypoScript:
tt_content {
gridelements_pi1 = COA
gridelements_pi1 {
20 {
10 {
setup {
SectionColoured < lib.gridelements.defaultGridSetup
SectionColoured {
cObject = FLUIDTEMPLATE
cObject {
file = EXT:myext/.../SectionColoured.html
}
}
}
}
}
}
}
Now, I upload an image (e.g. for background-image) via flexforms, like this:
<backgroundimage type="array">
<TCEforms type="array">
<label>LLL:EXT:autefa/Resources/Private/Language/backend.xlf:gridelements.SectionColoured.flexforms.backgroundimage</label>
<config type="array">
<type>inline</type>
<maxitems>1</maxitems>
<foreign_table>sys_file_reference</foreign_table>
<!--<foreign_field>uid_foreign</foreign_field>-->
<foreign_table_field>tablenames</foreign_table_field>
<foreign_label>uid_local</foreign_label>
<foreign_sortby>sorting_foreign</foreign_sortby>
<foreign_selector>uid_local</foreign_selector>
<foreign_selector_fieldTcaOverride type="array">
<config>
<appearance>
<elementBrowserType>file</elementBrowserType>
<elementBrowserAllowed>jpg,png</elementBrowserAllowed>
</appearance>
</config>
</foreign_selector_fieldTcaOverride>
<foreign_match_fields type="array">
<fieldname>image</fieldname>
</foreign_match_fields>
<appearance type="array">
<newRecordLinkAddTitle>1</newRecordLinkAddTitle>
<headerThumbnail>
<field>uid_local</field>
<height>64</height>
<width>64</width>
</headerThumbnail>
</appearance>
</config>
</TCEforms>
</backgroundimage>
That works so far. How can I use the image in my FLUIDTEMPLATE? The debugger returns 12 on {data.flexform_backgroundimage} ?!
<f:debug>{data.flexform_backgroundimage}</f:debug>
<section class="main-content {data.flexform_farbe}">
<article>
<f:format.raw>{data.tx_gridelements_view_columns.101}</f:format.raw>
</article>
</section>
Debug {data}.. THanks for your help!
pi_flexform => array(1 item)
data => array(1 item)
general => array(1 item)
lDEF => array(2 items)
farbe => array(1 item)
backgroundimage => array(1 item)
vDEF => '12' (2 chars)
Edit: image

It's funny. If I try it with the TYPO3 Fluid ViewHelper:
<section style="background-image:url({f:uri.image(src: '{data.flexform_backgroundimage}', treatIdAsReference: 1)})">
<article>
<f:format.raw>{data.tx_gridelements_view_columns.100}</f:format.raw>
</article>
</section>
I'll get an error You must either specify a string src or a File object.
Now I use vhs:
{namespace v=FluidTYPO3\Vhs\ViewHelpers}
<section style="background-image:url({v:uri.image(src: '{data.flexform_backgroundimage}', treatIdAsReference: 1)})">
<article>
<f:format.raw>{data.tx_gridelements_view_columns.100}</f:format.raw>
</article>
</section>
And everything works .. here's the view helper reference of the vhs extension. Thanks for the helping guys!

Since FAL is working with records instead of plain text paths to the image, you have to use the ID of the record to get the actual image file.
Since I am not 100% sure, you should check if 12 is the ID of the sys_file_reference record or the sys_file record used for that particular image before using the usual < f:image> viewhelper either with or without "treatIdAsReference".
https://docs.typo3.org/typo3cms/ExtbaseGuide/Fluid/ViewHelper/Image.html
If you just need the path to the image and not an image tag you should go for < f:uri.image> instead.

This is how I did it some time ago, using the media field of tt_content instead of using flexform. This solution assumes that
a) you are using a "frontend provider" extension (EXT:yourext) that stores your TypoScript and Fluid Templates
b) EXT:yourext depends on EXT:gridelements
c) In this example, my gridelement object is called twocolumnscontainer
1) TS Constants: use EXT:yourext as alternative path for fluid templates, layouts, partials
styles.templates.templateRootPath = EXT:yourext/Resources/Private/Templates/ContentElements/
styles.templates.partialRootPath = EXT:yourext/Resources/Private/Partials/ContentElements/
styles.templates.layoutRootPath = EXT:yourext/Resources/Private/Layouts/ContentElements/
2) in TS Setup, define the template cObject for content grids
lib.gridelements.defaultGridSetup.cObject =< lib.contentElement
tt_content.gridelements_pi1.20.10.setup.twocolumnscontainer < lib.gridelements.defaultGridSetup
tt_content.gridelements_pi1.20.10.setup.twocolumnscontainer {
cObject.templateName = GridElementTwoColumns
cObject.dataProcessing {
10 = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
10 {
references.fieldName = media
as = backgroundimage
}
}
}
3) In TS Config:
tx_gridelements.setup.twocolumnscontainer {
title = Two columns element with background image
description = whatever
config{
colCount = 2
rowCount = 1
rows {
1 {
columns {
1 {
name = column 1
colPos = 100
}
2 {
name = column 2
colPos = 101
}
}
}
}
}
}
4) EXT:yourext/TCA/Overrides/tt_content_element_gridelement.php
<?php
defined('TYPO3_MODE') || die();
call_user_func(function()
{
/**
* Limit the number of images in "media" for gridelements contents
*/
$GLOBALS['TCA']['tt_content']['types']['gridelements_pi1']['columnsOverrides']['media']['config']['maxitems']=1;
});
5) Define the Fluid template (I removed the classes so you can use whatever you want, Bootstrap, Foundation...):
EXT:yourext/Resources/Private/Templates/ContentElements/GridElementTwoColumns.html
<f:layout name="Default"/>
<f:section name="Main">
<f:if condition="{backgroundimage.0}">
{f:uri.image(image:backgroundimage.0)}
</f:if>
<div class="">
<div class="">
{data.tx_gridelements_view_column_100-> f:format.raw()}
</div>
<div class="">
{data.tx_gridelements_view_column_101-> f:format.raw()}
</div>
</div>
</f:section>
I hope I have not forgotten important steps :)

This should work for you:
<f:uri.image src="{data.flexform_backgroundimage}" treatIdAsReference="1"/>
