Expression Engine - Pass loop variable into embeded template - expressionengine

Question

have some trouble with Expression Engine variable passing in templates.
There is some piece of code:
// query:
{exp:channel:entries
channel="static"
}
// repeating field in a loop
{content_matrix}
<div>
{text_cell}
</div>
{image}
{/content_matrix}
//
{/exp:channel:entries}
I want to move content_matrix field with big inner HTML (example is shorter) sctructure into separate embed template for reusage in other templates.
Tried to build such embed but it doesnt work:
{embed="incl/content_matrix" matrix="{content_matrix}"}
And body of smaller template:
{embed:matrix}
<div>
{text_cell}
</div>
{image}
{/embed:matrix}
In this way it works if you passing single element, like ID, but not for mupltiple element.
Maybe it needs to pass entire entry.
How it can be done?
Thanks.

Answer 1

Have you considered using the Stash add-on?
I imagine you can stash the matrix content dividing between different parts of your html with some kind of separator, then in the embedded template wrap a search/replace for the separators with the proper html around the grabbed stash.
It might be less of a pain to write a quick, custom plugin, though.

Embed variables pass parsed output, not tags. So in your example:
{embed="incl/content_matrix" matrix="{content_matrix}"}
What you're actually passing in the matrix parameter is the full HTML table output of the data in that particular entry (since Matrix fields output a table when used as a single tag).
I think what you actually want to use to prevent repeating yourself is a Snippet. So just make a snippet containing:
{content_matrix}
<div>
{text_cell}
</div>
{image}
{/content_matrix}
And save it as, say, matrix_loop. Then include it inside your Channel Entries loop like so:
{matrix_loop}
