Option "alias" for fields

[dreistromland-tj]

It would be nice to have an option to set an alias variable name for fields. This would make templating a bit more flexible when reusing fields.

Example:
I have an image field and want to reuse the image column. That means that I have to use data.image in the templates.
But I have a shared layout like that:

<div class="inner-wrap">
    <f:render section="Main"/>
</div>

<f:if condition="{data.intro_image}">
    <f:for each="{data.intro_image}" as="file">
        <f:render partial="IntroImage" arguments="{file: file}"/>
    </f:for>
</f:if>

That means, that only intro_images should be displayed there. I therefore cannot reuse the image column as using data.image in the layout would render the image for all content-blocks. With an alias, multiple content blocks could use the image column but use different variables in the templates.

Adding a new field intro_image is of course not much of work but it feels cleaner if I can reuse a column 😉

It's an edge case, I know. But maybe there are some more cases where an alias could be helpful.

This is not an edge case, I think many would benefit from this!

For a workaround, why not having a partial handling the whole if condition already and passing the "image" to the partial as argument ... and not only the "file" ?

Instead of

<f:if condition="{data.intro_image}">
    <f:for each="{data.intro_image}" as="file">
        <f:render partial="IntroImage" arguments="{file: file}"/>
    </f:for>
</f:if>

something like:

<f:render partial="IntroImage" arguments="{partialImages: data.intro_image}"/>

and doing the if and for loop in the partial based on the passed partialImages variable ?
All templates using the partial needs to be adopted to pass the image down to the partial unrelated on howthe field is named/called in the partial calling fluid file (partial, layout, template, ...)

Aka thinking and using partials more in way of a component. In newer TYPO3 versions instead of a partial a fluid component could also be a alternative coming with arguments and slots and similar (not sure if they are usable in layouts to be honest).
