Assembling dynamic pages, duplication of header material

Folks:
DW CS3
Consider a home page, "index.php" which conditionally
REQUIREs one of N HTML files containing pure content. All site
styles are are specified in a master CSS file called
"siteformatting.css" I've illustrated this schematically at the end
of this message.
I think that "index.php" must link to the master CSS file, so
that HTML elements in this file can conform to site-wide standards,
right?
The content files must certainly link to the master CSS file.
In fact, these content files must be fully valid stand-alone HTML,
otherwise they will not pass DW file-->Validate-->Markup, and
maybe other difficulties occur, correct?
What I find is that all this works consistently during
authoring in DW, but, when a page is served up, the recipient
browser sees duplication of header (and trailer) material,
including two identical header links to "siteformatting.css".
Sure enough, the HTML Validator (0.8.5.2) extension to
FireFox reports the duplications with multiple warnings.
The obvious way deal with this is to ignore the warnings from
HTML Validator. They aren't errors, and thus far I haven't seen any
ill effects from the duplication.
Or I could to push all the HTML out of "index.php" into
stand-alone HTML files. But I'm reluctant about breaking up the
home page into multiple files -- that seems ... very inconvenient
for managing the site look. (Yes, my actual design is much more
complex than the schematic description I'm using here, so I think
it would require a dozen or more HTML files.) The only other option
I can imagine is finding a way to persuade DW to pseudo-include the
master CSS file for editing purposes but to omit the link to it in
the actual code. Can DW do that?
For a bonus, please correct any of my terminology that isn't
clear. (I'm self-taught...)
For an extra bonus, please let me know if there is a better
place to bring up such questions, which I'll admit are only
tangential to DW. (Except the issue of pseudo-including CSS in DW,
which is valid but probably a bit bizarre and/or naive.)
TIA,
Henry

Form in Dynamic page not working when checkbox is used.

I have created a form using dynamic page. The form most have display fields and a checkbox field. When I check a box, it assigns 'Y' value and when unclick, it assign 'N' to the database field.
When I submit the form, the procedure which is supposed to save the form data never gets executed. Well, at least it says, page not found HTTP 404 error.
Interestingly if I make this field a text box and manually enter 'Y' or 'N', and then submit the form, the procedure is executed. Data gets saved.
Is the checkbox not supposed to be used for a database field because checkbox value can be assigned only using javascript and the procedure never get that value ?
Can you please tell me how to use a checkbox for a database field using dynamic page ?
thanks,
Mainak

Sharmila,
When I said, the form does not get submitted, I meant that the procedure does not work. The form gets submitted but the procedure does not work. It gives HTTP 404 error. That is what perplexes me. I am unable to understand why the procedure does not work when I click a checkbox.
May be you can make this work. I am hopeless about this.

Has anyone tried changing the color of the table header in Dynamic Pages?

When you generate the sample Dynamic Page you get a table header with the color of #C0C0A0.
Has anyone ever found where this value is coming from within the database ?
I'd like to change it so I can control the background color in the TH tag for Dynamic Pages.
TIA

Displaying header and border on a dynamic page passing parameters to a form

I am using portals 10.1.4. and am trying to pass parameters to a form which appears as a portlet on a page.
for this, dynamic page has been used to pass parameters to that desired form. my problem is this that when the form is displayed with parameters, the header and borders of the portlet disappear.
The check-boxes for header and borders of the portlets on the page are checked. Yet, when for any reason, the parameters are not passed into the dynamic page, the header of the dynamic page and border are displayed. But when the parameters are passed and the form shows up, then the header and borders disappear.
can anyone help me with the following:
- is it the desired behavior?
- how can i get the headers and borders reappear?
thanks

Any ideas fellows?
how can we control the border and header of dynamic pages when a form or report is called from them with passed parameters?
will appreciate any helpful experiences.

In a dynamic page how to share variable between PL/SQL and javascript

For example, my dynamic page contains such PL/SQL codes:
<ORACLE>
DECLARE
info varchar(100);
rowid urowid;
procedure doDelete(
row_id in urowid
) IS
begin
Delete From xxx
WHERE rowid = row_id;
end doDelete;
BEGIN
Select name, rowid INTO info, rowid
From xxx Where xxx;
HTP.PRN(' <INPUT TYPE="button" VALUE="show value" onClick="alert(info);">');
HTP.PRN(' <INPUT TYPE="button" VALUE="delete" onClick="doDelete(_row_id);">');
END;
</ORACLE>
The variable 'info' and '_row_id' are correct, however the two HTP. sentence do not work. What's the problem?
What I want to do is to show all the records in TABLE A in a page. And at the end of each line (record), there' re a 'delete' and a 'update' button to let user operate on this record. Is this possible? I know form can do delete an update, but it can not show all the records in a page like what report does. Besides dynamic page, is there any other better choice? Report can do it?
One more question. In a report, I employed link on one field to a second report. It works well. But I want to open the second report in a new window when the link is click. Is this possible?
I was almost driven crazy by these :( I so appreciate if anyone can help.

The code written by you is insufficient for the funtionality you are trying to achieve. Below is a method to achieve the same.
Note: Used standard scott.emp table for the example which is located in my db provider schema.
Do the below modifications as per your local configuration
xxxxx -> Replace it with your Portal schema
yyyyy -> Replace it with your db provider schema
<<module_id_of_form>> -> Replace with the module id of form created in step 1 & 2.
First and foremost... oracle does not allows variables starting with '_'. So if you want to use it you have to place it in double quotes ("")
rowid -> illegal
"_row_id" -> legal.
However, I will advice you not to use variable names starting with "_".
Now lets get started...
1. Create a form on the table you are using in the dynamic page. Just have the update button. Remove the other buttons.
2. Get the module id of this form. Instruction for getting the module id:
a) Right-click on the form's run link and copy the shortcut
b) Get the value of p_moduleid parameter. This is your module id.
3. Create a procedure "save_action_details" in your db provider schema. This procedure will accomplish the delete operation on the record.
     CREATE OR REPLACE Procedure save_action_details(
     p_rowid IN VARCHAR2,
     p_action IN VARCHAR2,
     p_dyn_ref_path IN VARCHAR2,
     p_dyn_page_url IN VARCHAR2)
     is
     l_sto_session xxxxx.wwsto_api_session;
     begin
     l_sto_session := xxxxx.wwsto_api_session.load_session(
     p_domain => 'DynStore',
     p_sub_domain => 'DynStore_' || p_dyn_ref_path
     l_sto_session.set_attribute(
     p_name => 'rowid',
     p_value => p_rowid
     l_sto_session.set_attribute(
     p_name => 'action',
     p_value => p_action
     l_sto_session.save_session;
     htp.init;
     owa_util.redirect_url(p_dyn_page_url);
     end save_action_details;
Explaination: The above procedure creates a session and keeps the rowid and action in the session. This information is used by the below dynamic form to perform the necessary action. In our exampl, the action is always going to be delete so you may go ahead and hard code it, else leave it as it is.
4. Grant execute privilege on the procedure "save_action_details" to public.
sql> grant execute on save_action_details to public;
5. Create your Dynamic page.
a) In HTML code section have the below code. This code shows some columns from the table and "update" and "delete" buttons to perform the respective action.
     <ORACLE>select empno,ename,rowid,
     '<input type="button" value="Update" onClick="doAction(this.form,''UPD'',''xxx'','''
     || xxxxx.wwv_standard_util.url_encode(rowid) || '''); tWin();">
     <input type="button" value="delete" onclick="doAction(this.form,''DEL'',''' || rowid || ''',''xxx'');">' Action
     from yyyyy.emp</ORACLE>
b) In additional pl/sql code section of dynamic page, have the below pl/sql block "in after displaying the header" section.
     declare
     l_sto_session xxxxx.wwsto_api_session;
     l_del_rowid varchar2(20);
     l_action varchar2(10);
     begin
     htp.comment('User code starts here ...');
     htp.p('<script>');
     htp.p('var winHandle;');
     htp.p('
     function doAction(formObj, action, rowid, erowid)
          if (action == "UPD")
          var formURL = "' || xxxxx.wwctx_api.get_proc_path('wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=<<module_id_of_form>>&p_arg_names=_rowid&p_arg_values=') || '" + erowid;
          winHandle = window.open(formURL, "winDynUpd", "width=750,height=500,resizable=yes");
          else
          formObj.p_rowid.value = rowid;
          formObj.p_action.value = action;
          formObj.submit();
     function tWin() {
          if (winHandle.closed) {
          document.location = document.location;
          else {
          setTimeout("tWin()", 500);
     htp.p('</script>');
     htp.p('<form name="dynRowProcess" method="POST" action="'
     || xxxxx.wwctx_api.get_proc_path('save_action_details','yyyyy')
     || '">');
     htp.p('<input type="hidden" name="p_rowid">');
     htp.p('<input type="hidden" name="p_action">');
     htp.p('<input type="hidden" name="p_dyn_ref_path" value="' || p_reference_path || '">');
     htp.p('<input type="hidden" name="p_dyn_page_url" value="' || p_page_url || '">');
     l_sto_session := xxxxx.wwsto_api_session.load_session(
     p_domain => 'DynStore',
     p_sub_domain => 'DynStore_' || p_reference_path
     l_del_rowid := l_sto_session.get_attribute_as_varchar2('rowid');
     l_action := l_sto_session.get_attribute_as_varchar2('action');
     if l_action = 'DEL' then
     delete from yyyyy.emp
     where rowid = l_del_rowid;
     end if;
     end;
Explaination: The session information (rowid and action) stored by "save_action_details" procedure is retrieved by the dynamic page and is used to delete the record.
6. Once you are through with the above steps, test it by placing the above "dynamic page" portlet on a page.
a) When you click on delete button the record gets deleted and the automatically refreshed page will not show the deleted record.
b) On clicking update button, a form will appear. do the necessary modifications in data and click update. the data in the form gets updated. Once you close the form the dynamic page gets refreshed automatically and it will show you the updated information.

Bob,
You have variables in your procedure like l_status, p_alternate_status which you do not have in the form. Are these IN or OUT variables ?
If these are IN variables, this proc will not work because you do not have any variable in the form. So from where does it get the values? There is not any default declared too. You have to explicitly define IN or OUT variables.
Have you also given execute permission to public ?

Dynamic lenght in report heading

Hi experts,
I need to pass dynamic length in report heading.
i.e.., REPORT zrep LINE-SIZE dyn_len NO STANDARD PAGE HEADING.
So that my report output width will be in different length based on value dyn_len.
Any solution or alternative in simple list display. Pls suggest ....
Thanks in advance.
Zak.

Hello,
Do not specify LINE SIZE in that case.
Thanks,
Jayant

Passing value from dynamic page to form.....

I have a portal page that has a dynamic page where I've created an html form. Also on this same page in different regions are three other forms which were created by the form wizard. From the dynamic page form I want to pass a session value to the other forms on the same page. Is this possible? I know it's possible from form to form using session apis. I've search the forum and have not found what I'm looking for. Can anyone be of any help on this topic?

Melissa,
It seems we have the same type issue.
Session variable how to's are what I need also.
There is a site with more information on it...a continuation of the Portal Handbook by Vandivier and Cox at home.covad.net/~idbexperts called an "Unpublished Case Study" - I don't know if it'll hit your needs on the head, but it may help to see it.
I believe I am trying to hold session variables over til users complete a 4 part form across several pages (may be a space problem we have). Do you know how I start this?
I don't know how to put p_session variables together, when or where the parameters are necessary and whether a procedure is necessary or not!!!
If you would like to correspond offline, I am at [email protected] and would appreciate your insights.

Auto Query in Master Detail Form using dynamic page doesn't work

I created a Master-Detail form, and implement AutoQuery using a dynamic page
with the following code :
<HTML>
<BODY>
<ORACLE>DECLARE
nre_ VARCHAR2(100);
BEGIN
nre_ := emp_nre;
if nre_ is not null then
net_portal.Popula_Agregados(nre_);
net_portal.Popula_Docs_Agregados (nre_);
htp.p('<iframe id=myFrame name="myFrame" frameborder=0 width="250%"
height="300"
src="/pls/portal/PORTAL.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=
3
388118140&p_arg_names=_show_header&p_arg_values=NO&p_arg_names=_cad_nre_cond&p_a
rg_values=%3D&p_arg_names=cad_nre&p_arg_values='||nre_||'">
</iframe>');
end if;
EXCEPTION
WHEN OTHERS THEN
htp.p(SQLERRM);
END;
</ORACLE>
</BODY>
</HTML>
It works fine when we access the first time to the page, but if i press the
save button after inserting or updating a detail record, the header record is
lost. How can i avoid this situation ?

I changed query:
select
Replace(
'<img src="#IMAGE_PREFIX#ed-item.gif" border="0" alt="EditMap" usemap="#editmap***id***"></img>
<map name="editmap***id***">
<area shape="rect" coords="0,0,16,16" href="http://apex.oracle.com/pls/otn/f?p=&APP_ID.:'
|| decode ( type, 'FOLDER', '33', '22' )
|| ':&APP_SESSION.::&DEBUG.::P'
|| decode ( type, 'FOLDER', '33', '22' )
|| '_ID,P'
|| decode ( type, 'FOLDER', '33', '22' )
|| '_CALLING_PAGE:' || id || ',&APP_PAGE_ID." ></area></map>' ,
'***id***', id
) Edit,
id,
type,
name,
decode ( type, 'FOLDER', 33, 22 ) target
from tThe idea is - each img uses its own map.
It works now.

Why is the template not being used when dynamic page called ?

Hi,
I have created a dynamic page and assigned a template to it. When I call the dynamic page using the 'show' procedure from a form, I do not see the template.
Why is the template not being used ? How can I get the template working when I call the dynamic page ?
I even tried to show the page from the dynamic page's manage components tab and there is same problem. Template is not being used.
thanks,
Mainak

You can alter the generated package body to include the following function in the header and footer sections.
Header:
PORTAL.wwv_headings.show_header(
p_template => 'PUBLIC.TEMPLATE_3',
p_heading => 'Dynamic Page',
p_help_link => 'PORTAL_DEMO.EXAMPLE_DYNAMIC_PAGE.help',
p_about_link => 'PORTAL_DEMO.EXAMPLE_DYNAMIC_PAGE.about');
Footer:
PORTAL.wwv_headings.show_footer(
p_template => 'PUBLIC.TEMPLATE_3',
p_help_link => 'PORTAL_DEMO.EXAMPLE_DYNAMIC_PAGE.help');
where
<PORTAL_DEMO> indicates application schema
<PORTAL> indicates the name of the portal (normally this will be portal30 by default).

Great questions, Rik, and I understand how this might seem bizarre. Here's the story... these 2500 files were authored with a built-in authoring tool of our current knowledge management system. This KMS is about to be replaced with a new one and because the new KMS needs content within the <head> tag instead of where it was in the <body> tag and redefined as meta data, I repuposed the content in those files using Dreamweaver and regular expressions. However, the one remaining <h3> and <p> content is in the middle of the newly tagged meta data and it must be moved from the <head> area and into the <body> area.
Because these were authored in the built-in KMS authoring tool, there is no style sheet and no, we do not manage our content with a CMS.
You are correct, if the <h3> and <p> were at the end of the data, I could simply move the </head> and <body> tags, but unfortunately that is not the case. They are consistenly in the same place in all 2500 files, but in the middle of the data. Following is an example:
<html>
<head>
<title>Title here</title>
<meta name="XYZ" content="Something here...">
<h3> Blah blah</h3> <p>More blah blah</p>
<meta name="123" content="More somthing here">
<meta name="456" content="More somthing here">
</head>
<body>
</body>
</html>
Again, I can find the block using a regular expression <h3>(.*?)</p>, but dont know what to do after that.
I've been told that perl or grep might do the needed task, but that requires outside resources and I have no budget for that.
Any suggestions are greatly appreciated.
thanks,
Rick

Pass parameter from dynamic page to form

I have a report that uses a link to pass a parameter (projno) to a dynamic page. This dynamic page calls a procedure which, using the projno, pulls information from four tables. Depending on who the user is and what phase the project is in, each heading can be a link to a form so that the proper user can update the project. For instance, the projetc manager can update the progress table during phases 2-9. So I want the Progress Heading to be a link to a form so that the project manager can update the progress for a specific project number. I tried to put the link in the procedure like this:
if iPhase in (2,3,4,5,6,7,8,9) then
          htp.p('<TD><a           href="/pls/portal/PORTAL.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=6803259033&p_arg_names=projno&p_arg_values='||projno||'&p_arg_names=_projno_cond&p_arg_values=%3D&p_arg_names=_sessionid&p_arg_values=" target="_blank"><FONT FACE="VERDANA" SIZE="2">Progress</FONT></a></TD><TD width="10"></TD>');
     else
          htp.p('<TD><FONT FACE="VERDANA" SIZE="2">Progress</FONT></TD><TD width="10"></TD>');
     end if;
But it brings up a blank form... no parameters are passed. Help!?

when I use :projno I get a "bad bind variable" error. But really, I don't think that's the problem. Using the code in my last message, I can mouseover the link and see the correct information:
http://spring.ous.edu:7778/pls/portal/PORTAL.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=6803259033&p_arg_names=projno&p_arg_values=14&p_arg_names=_projno_cond&p_arg_values=%3D&p_arg_names=_sessionid&p_arg_values=
When I actually click on the link however, this is the URL now displayed in the address field:
http://spring.ous.edu:7778/pls/portal/PORTAL.wwa_app_module.show?p_sessionid=2592
It strips the url of the projno information.
