DISCUSS - the strange application of the $modx->documentIdentifier

It’s well known to everyone that It’s based on the two parameters--’documentMethod’ and ’documentIdentifier’’’ to get some docment . U can find details in the file named "document.parser.class.inc.php" . (it means that if u want to indicate some DOCment ,the 2 parameter are indispensably ) and U can see there are no changed on the two parameters after them appear.

But in some snips and chunks, there is only one parameter-documentIdentifier. Such as Dropmenu , UserComments.

And in the logistic, is it hidden erro !!!!!

PS: the problem is find because i want to change the core code to fit the setting of Shared Server

我们在document.parser.class.inc.php中可以发现，要查询某一文档的时候，必须拥有两个参数：’documentMethod’ 和 ’documentIdentifier’’’，并且这两个参数在核心代码中一直没有被改变过。
但是我们在检验其他代码的时候，比如下拉菜单的dropmenu和评论UserComments的时候，发现他们标志判断一个文档的时候只用了一个参数：documentIdentifier，那么即使现在我们没有出任何差错，但是在逻辑上说，是否这样的设置是不行的呢？

$modx->documentIdentifier is always changed to numeric (and method to id) by the time a snippet gets to it. This is an internal mechanism and should never be modified in the course of a request.

Thanks for giving directions. can U show some details about the " internal mechanism" , because i can’t find any trail of modify in the php code. Maybe miss them . Maybe by the RewriteMod of Apache Server.

In any case, now it works well beacause i put some code before the evalSnippets($source)


Thanks.
Sorry for my poor English.

In the function cleanDocumentIdentifier the value of documentMethod is determined and set. Also in the ExecuteParser function, around lines 1006 - 10013 is some more code to check and set the value. The function getDocumentMethod also sets this value.

Thanks For reply so quickly .

And we’ll check the original fuction 。 Because now , we steer clear of Functions cleanDocumentIdentifier and cleanDocumentIdentifier .
