Two forms of each placeholder are available. In the first form, (yams_???), the placeholders provide information about the current document. In the second form, (yams_???:_docId_), they provide information about the document with the given document identifier, _docId_.

It should be possible to use snippet calls and chunks to specify the document identifier. (yams_doc:[+id+]) can be used within templates.

It should be possible to use YAMS placeholders almost anywhere, including in chunks, in the names and output of template variables, and in the names, output and parameters of snippet calls.

When the output of a YAMS placeholder is language dependent it needs to know what the current language is. The current language is dependent upon the context. The (yams-in) or (yams-repeat) blocks allow the inclusion of alternate language content on a page. (See the Constructs tab).

If a placeholder falls within either of these blocks, then the current language is that specified by those blocks. Otherwise the current language is taken to be the language in which the current page is being displayed. There may be occasions when it is necessary to override this behaviour and force the placeholder to treat the current document language as the current language.

This can be achieved by appending a + symbol to the end of the name of the placeholder. For example, the following will generate a (yams-repeat) block that will display a list of the names of the available languages, all written in the current document language:

<ul>[[YAMS? &get=`repeat` &repeattpl=`@CODE:<li>(yams_name_in_(yams_id+))</li>]]</ul>

Placeholder : ((yams_data:_docId_:_fieldname_)) / ((yams_data:_docId_:_fieldname_:_phx_))

Monolingual Document : This special inline placeholder is different from all the others. It is used by YAMS for efficiently grabbing template variables from documents. Here, _docId_ is the id of the document to grab the template variable from and _fieldname_ is the name of the template variable from which to get the data. In future, this syntax will allow phx to be used, but this is not currently supported.

YAMS will search out all these placeholders in the document, work out what information needs to be grabbed from the database and grab in large chunks so as to minimise the number of database queries required.

The [[YAMS? &get=`data` snippet call (same as the legacy [[YAMS? &get=`content` snippet call) which is used in the Wayfinder templates and internally by the YAMS Ditto extension will now output such placeholders meaning improved performance for large Ditto and Wayfinder calls.

As of YAMS 1.2 this will work with document variables as well as template variables.

Multilingual Document : Same as for monolingual documents

Placeholder : (yams_multi) / (yams_multi:_docId_)

Monolingual Document : Outputs 0. This parameter is due to appear in YAMS 1.2, and can be used in combination with PHx, for example, to exclude or include content based on type.

Multilingual Document : Outputs 1. This parameter is due to appear in YAMS 1.2, and can be used in combination with PHx, for example, to exclude or include content based on type.

Multilingual Document : Outputs 0. This parameter is due to appear in YAMS 1.2, and can be used in combination with PHx, for example, to exclude or include content based on type.

Multilingual Document : Outputs multi. This parameter is due to appear in YAMS 1.2, and can be used in combination with PHx, for example, to exclude or include content based on type.
