Concatenate strings and variables in assignment of new variable in smarty

Question

I want to concatenate an already assigned variable and save it to a new variable, something like this:

{assign var=permCat value="de.admin"}
{assign var=objectName value="myClass"}
{assign var=objectNameUpper value=$objectName|ucfirst}
{assign var=editPerm value=$permCat|cat:"canEdit"|cat:$objectNameUpper}

So, the resulting $editPerm should be: de.admin.canEditMyClass

How can I do this? Currently, it throws an error: Cannot use string as array offset...

On which of the four lines the error is thrown?

The error you describe cannot be caused by the given code. I assume you are trying to build a string "de.admin.canEditMyClass" to use as a variable {$builtString.foo}. That's where the error occurs, because smarty does not magically convert your string to a variable reference.

If you're using Smarty2:

{assign var=objectName value="myClass"}
{assign var=objectNameUpper value=$objectName|ucfirst}
{assign var=editPerm value="canEdit"|cat:$objectNameUpper}
{$de.admin.$editPerm.foo}

If you're using Smarty3:

{$de.admin.{"canEdit"|cat:{"myClass"|ucfirst}}.foo}
