Am getting an exception in fluid template as follows.
#1314516810: File /uploads/tx_sfel_sfel/img_uploads/ffffff.jpg/ does not exist.
This image is not present in the 'img_uploads' directory.
But I don't want to show this exception.
How to prevent the page from showing this error.
Please help me to find a solution.
Thanks in advance.
You can install VHS and use the Viewhelper to check if there is this image. It will look like this:
{namespace v=FluidTYPO3\Vhs\ViewHelpers}
.
.
.
<v:media.exists file="{filepath}" >
<f:then>
[Your Image]
</f:then>
</v:media.exists>
.

I am making a sitepackage to be compatible with TYPO3 9 & 10. However it is using the news extension which changes the way pagination is done.
Is there a way in fluid to do something like:
<f:if condition="n:widget.paginate">
<f:then>
Use n:widget.paginate
</f:then>
<f:else>
Use newer paginate method
</f:else>
</f:if>
By default there is no such condition.
You might define a view helper to check the installation of an extension and the extension version. Or you use a view helper to check the existence of a class representing the view helper.
In ext:vhs you find a view helper to check if an extension is loaded and a try view helper to catch a rendering error.
Problem
There is the requirement, to swap out the logo, based on a choice, the user makes on first visit. (Logo for internationals and logo for north America)
What I came up with
On fist thought this problem can be solved using a cookie. I implemented some javascript, to check and set the cookie if needed. This works fine so far but using javascript to change to logo isn´t the way to go and now I´m looking for possible solutions to this.
Some thoughts
If following the cookie approach, I´d need a way to swap out the template/partials, based on the cookie. Is there any way to do this using fluid or typoscript perhaps?
Maybe the cookie approach is the wrong way to handle this at all? Maybe this could be done (ab-)using the language selection or something like that?
Any help or ideas are appreciated.
Thanks!
First of all: Please use a question title that describes the problem more precise.
After setting the cookie with your javascript, you can set the logo to render in the TypoScript.
With a condition (https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/Conditions/Index.html#request-getcookieparams) you can read the cookie parameter and set the logo depending on the cookie.
[request.getCookieParams()['logo'] == 'us']
lib.logoFile = pathToYourLogos/us.svg
[else]
lib.logoFile = pathToYourLogos/international.svg
[end]
Thanks to #thomas-löffler and #jonas-eberle for pointing out the right direction. Thomass solution is meant for Typo3 >= 9. This solution that worked for me on Typo3 ver. 8.7 (also see this solution):
Get the cookie value inside typoscript (setup) like this:
lib.requestedLocation = TEXT
lib.requestedLocation.data = global:_COOKIE|<cookie-name>
After getting the cookie value we can use it with fluid like this:
<f:variable name="location" value="{f:cObject(typoscriptObjectPath: 'lib.requestedLocation')}" />
<f:if condition="{location} == 'america'">
<f:then>
<img class="logo" src="/path-to-us-logo.svg">
</f:then>
<!-- defaulting to international if cookie is not set or somehting else is wrong -->
<f:else>
<img class="logo" src="/path-to-international-logo.svg">
</f:else>
</f:if>
I'm a typo newbie, and was wondering, how I can make the following code work in my HTML Template file:
<img src="EXT:extension-name/Resources/Public/Images/Logo/logo-white.png" alt="logo.png">
Looking forward to your anwers, thanks.
This cannot be done in an HTML file but within a Fluid template file you should use the uri.resource viewhelper:
<img src="{f:uri.resource(path: 'Images/Logo/logo-white.png')}" alt="Actual explanation of the logo content">
If used within an Extbase plugin there is nothing else to do.
For templates using the FLUIDTEMPLATE content object you'll need to set the extension name, for example with an extensionName: 'MyExt' as argument:
<img src="{f:uri.resource(path: 'Images/Logo/logo-white.png', extensionName: 'MyExt')}" alt="Actual explanation of the logo content">
Alternatively use controllerExtensionName in your TypoScript setup.

Hello
it's hard to explain ...
If you're using TYPO3 7.6 (w. fluid styled content) with the module "file links", you can upload single files, but you can also work with the "file collection" to organize your downloads in a sys-folder.
There're three different types of "file collections". 1. Static selection of files and 2. Folder from Storrage and 3. Select by category.
Now you've upload and edit your FAL-files (metadata, s. image below) with a new title and description. These fields e.g. {file.title} will show with fluid_styled_content (Uploads.html), if you're using a single download or a file collection static selection of files, but not, if you're using Folder from storrage! The title won't show, you only see the {file.name} ..?
I'm using the standard Uploads.htmlform FSC with an extra condition.
Test <f:debug>{file.title}</f:debug>, see below. There's no Title from files via "folder from storrage".
...
<f:if condition="{file.title}">
<f:then>
{file.title}
</f:then>
<f:else>
{file.name}
</f:else>
</f:if>
...
Is it a bug or a feature for TYPO3 8?
I hope my pictures can explain this behavior better.
There was a TYPO3 Core Bug, but now it's fixed (TYPO3 7.6.15) - update Core and Fluid Styled Content-Template Uploads.html
Line 26
<a href="{file.publicUrl}"{f:if(condition:data.target,then:' target="{data.target}"')}>
<span class="ce-uploads-fileName">
<f:if condition="{file.properties.title}">
<f:then>
{file.properties.title}
</f:then>
<f:else>
{file.name}
</f:else>
</f:if>
</span>
</a>

In my Typo3 extension I'm showing a lot of images with fluid, an list view of products. Only if for some reason one image is missing on my server, Typo3 generates an full screen error so the complete website is then not working.
I my opinion there are three way to prevent it:
1) Configure Typo3 so it is ignoring broken image url's. Does anyone know if this is possible?
2) Let Fluid check if the image exists before it is generated. Don't know if this is possible?
3) Use the controller to check if the image exists before it is send to the frond-end. Only due to the manny images it uses a lot of processing.
I prefer the use of the media exists viewhelper from the VHS Viewhelper package. After installing and activating the extension it should look like this screenshot in your TYPO3 extension manager.
This example iterates through a array of products, that have a public picture property holding the filename of it's picture.
{namespace v=FluidTYPO3\Vhs\ViewHelpers}
<f:for each="{products}" as="product">
<v:media.exists file="fileadmin/products/{product.picture}">
<f:then>
<f:image src="fileadmin/products/{product.picture}" />
</f:then>
<f:else>
<f:image src="fileadmin/noImageFound.jpg" />
</f:else>
</v:media.exists>
</f:for>
