Embed PDF file in HTML region

Question

Hi There
I have a simple report - with a link to view an underlying document. The document will be displayed on a seperate page with one HTML region. Say the file to display is statement.pdf and it is has already been uploaded to apex images. There is a hidden field P3_FILENAME on the display page. This gets set from the report. On the HTML region:
<div style="">
<embed height="600" width="1200" name="Statement" src="#WORKSPACE_IMAGES#&P3_FILENAME." type="application/pdf" />
</div>but it does not work. However, if I simply do this and 'run' the page - it displays fine.
<div style="">
<embed height="600" width="1200" name="Statement" src="#WORKSPACE_IMAGES#statement.pdf" type="application/pdf" />
</div>Looking at the source of the resultant failing page I can see that the values were correctly set.
Any ideas?
thanks

Answer 1

I think the HTML is looking for the explicit &P3_FILENAME. and can't find it because it is being referenced through the HTML rendering engine rather than the PL/SQL engine which would handle the variable substitution.
Try creating a PL/SQL region where you write out the div tags as strings using DBMS_OUTPUT.PUT_LINE. I use this to create some rather complicated reports and it works great for letting me do variable substitution amongst my HTML. Here's a simple example (mine's a procedure I call to feed in page variables):
create or replace PROCEDURE PROC_DASH_SAFETY(x_org NUMBER, x_dt DATE)
AS
  v_dt_disp        VARCHAR2(15);
  v_dt             DATE           := x_dt;
  v_org_id         NUMBER         := x_org;
  v_fact_id        NUMBER;
  v_org_nm         VARCHAR2(47);
  v_org_tz         VARCHAR2(4);
  ontime           VARCHAR2(47);
  v_saf_ct         PLS_INTEGER    := 0;
  v_eff_ct         PLS_INTEGER    := 0;
  saf_aud_t        NUMBER;
  saf_aud_a        NUMBER;
  eqp_aud_t        NUMBER;
  eqp_aud_a        NUMBER;
