Solution to get pageid from Oracle Portal in 14 Steps

Question

To get the _pageid from your site is simple you have to do this:
Example browser link -> portal/page?_pageid=34,35030&_dad=portal&_schema=PORTAL
1º - Edit your template page click in the "properties" link
2º - go to the tab Parameters
3º - create a new parameter with the name _pageid
4º - click in navigator and after click in providers
5º - Locally Built Providers and create your build APP for your site (in my case the name is APP_PORTAL)
6º - Create your dynamic page (in my case DYN_MENU to use a menu based in the pageid)
7º - uses this code:
/* the pageid have the number of your site (in this case psiteid) and the number of the page (in this case ppag)
after this you can call procedures using this two variables like the procedure menu who is create in the my package portal in the etcuser:
in the step or tab "Custumization Form Display Options" who detect the bind variable :pageid click in the option "Make public"
<ORACLE>declare
psiteid NUMBER(4);
ppag NUMBER(7);
begin
psiteid:=TO_NUMBER(substr(:pageid, 1, INSTR(:pageid, ',', 1, 1)-1));
ppag :=TO_NUMBER(substr(:pageid, INSTR(:pageid, ',', 1, 1)+1));
htp.p('Site: '|| psiteid ||' Page: '|| ppag ||'');
etcuser.portal.menul(ppag, psiteid);
end;
</oracle>
8º - After this you only need to associate in the template the _pageid parameter with bind variable :pageid of your dinamic page
9º - In your template add a Portlet to the region
10º - click in Portlet Staging Area - your build repository (in my case APP_PORTAL) and chose the DYN_MENU
11º - after click in the link properties of the template page go to the tab parameters again
12º - In the Portlet Parameter Values now you can expand your dinamic applications (in my case de DYN_MENU)
13º - Expand your application and associate the Portlet Parameter (in this case de pageid) equal (=) chose "Page Parameter" and select in the combo the _pageid
14º - The job is done now you have the pageid in your oracle portal pages

Answer 1

No... work's in oracle portal 10.1.4 if your system is configured to pass the pageid like my example. And my page only have one template for the entire portal and you only need to add the Dynamic page only one time in the template.
