my applications dont show the $modx->db function or other.
where is the cause?

Ehm, are you calling $modx inside the snippet, or you use external file to do it?

Try to use

at the beginning of your code, or inside the function where you use $modx.

Hope it helps.

I’m not sure exactly what you are doing, but in order to use the $modx object on a request/response of any kind, you have to build the object first. AJAX uses server requests and responses after the page has been generated on the client, so in order for your php file to have access to the MODx object, the script would probably have to create a new instance of it for use during that AJAX request/response cycle.

It can probably be done, but may not be the best approach from an AJAX performance perspective.

I think this is the issue at least; just guessing really...

I have resolved the problem with Pear Package (HTML_AJAX) and i dont utilize the $modx variable

When ajax call the the php file , the 4modx variable is not under the scope of this file and is not usable.

But i work (is 3 month) with YAML extension and MODX for a module communication. if the result is good this problem is resolved for all

Ok thanks for replys and sorry for my orrble english
bye

Another option is to put your php code in a snippet, then create a new document in the manager and choose the "blank" template for the page template.
When you POST to that document (for AJAX functions) it will only return the snippet output instead of the whole page template so you don’t get the [*content*] and all that stuff you DON’T want in an AJAX response.
