FilesProcessor¶
This data processor can be used for processing file information:
- relations to file records (
sys_file_reference
) - fetch files records by their uids in table (
sys_file
) - all files from a certain folder
- all files from a collection
A FLUIDTEMPLATE
can then iterate over processed data
automatically.
Options:¶
if¶
references¶
-
references
¶ -
If this option contains a comma-separated list of integers, these are treated as uids of file references (
sys_file_reference
).The corresponding file records are added to the output array.
stdWrap properties can also be used, see Example 2: use stdWrap property on references.
references.fieldName¶
references.table¶
files¶
collections¶
folders¶
-
folders
¶ -
- Type
- string (comma-separated folders), stdWrap
- Required
- false
- Default
- ""
- Example
- "23:/other/folder/"
Fetches all files from the referenced folders. The following syntax is possible:
t3://folder?storage=2&identifier=/my/folder/
- Folder
/my/folder/
from storage with uid2
23:/other/folder/
- Folder
/other/folder/
from storage with uid23
/folderInMyFileadmin/something/
:- Folder
/folderInMyFileadmin/something/
from the default storage0
(fileadmin
)
folders.recursive¶
sorting¶
-
sorting
¶ -
The property of the file records by which they should be sorted. For example, filesize or title.
sorting.direction¶
as¶
Example 1: Render the images stored in field image¶
Please see also About the examples.
TypoScript¶
Using the FilesProcessor
the following scenario is possible:
tt_content {
examples_dataprocfiles =< lib.contentElement
examples_dataprocfiles {
templateName = DataProcFiles
dataProcessing.10 = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
dataProcessing.10 {
as = images
references.fieldName = image
references.table = tt_content
sorting = title
sorting.direction = descending
}
}
}
The Fluid template¶
Then iterate over the files in the Fluid template:
<html data-namespace-typo3-fluid="true" xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers">
<h2>Data in variable images</h2>
<f:debug inline="true">{images}</f:debug>
<h2>Data in variable images</h2>
<div class="row">
<div class="row">
<f:for each="{images}" as="image">
<div class="col-12 col-md-3">
<div class="card">
<f:image image="{image}" class="card-img-top" height="250"/>
<div class="card-body">
<h5 class="card-title">{image.title}</h5>
<div class="card-text">{image.description}</div>
</div>
</div>
</div>
</f:for>
</div>
</div>
</html>
Output¶
The array images
contains the data of the files now:
![files dump and output](../Images/ManualScreenshots/FrontendOutput/DataProcessing/FilesProcessor.png)
Note
For technical reasons file references do not show all available data on using debug. See Using FAL in the frontend.
Example 2: use stdWrap property on references¶
The following example implements a slide functionality on root line for file resources:
page.10.dataProcessing {
10 = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
10 {
references.data = levelmedia: -1, slide
as = myfiles
}
}
The FilesProcessor
can slide up the root line to collect images for Fluid
templates. One usual feature is to take images attached to pages and use them on
the page tree as header images in the frontend.
Example 3: files from a FlexForm¶
If the files are stored in a FlexForm, the entry in
the table sys_file_reference
uses the name of the main table, for example
tt_content
and the FlexForm key as fieldname
.
Therefore, you can do the following:
page.10.dataProcessing {
10 = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
10 {
references.table = tt_content
references.field = settings.myImage
as = myImageFromFlexForm
}
}
This assumes that the image was stored in a FlexForm in the table
tt_content
like this:
<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<T3DataStructure>
<sheets>
<main>
<ROOT type="array">
<TCEforms><sheetTitle>Something</sheetTitle></TCEforms>
<type>array</type>
<el type="array">
<settings.myImage>
<TCEforms>
<label>My Images</label>
<config>
<type>file</type>
<maxitems>6</maxitems>
<allowed>common-image-types</allowed>
</config>
</TCEforms>
</settings.myImage>
</el>
</ROOT>
</main>
</sheets>
</T3DataStructure>
Three images in the same content element (uid 15) having the FlexForm above
would look like this in the the database table sys_file_reference
:
uid | pid | uid_local | uid_foreign | tablenames | fieldnames | ... |
---|---|---|---|---|---|---|
42 | 120 | 12 | 15 | tt_content | settings.myImage | ... |
43 | 120 | 25 | 15 | tt_content | settings.myImage | ... |
44 | 120 | 128 | 15 | tt_content | settings.myImage | ... |
