Conditional display HTML Portlet

Hi all, how can I conditionally display HTML portlet? I have a couple of html portlets on the page, but I want to use the page para to control the display of them. For Java/plsql portlets, it's fine. I don't know how to do that for html portlets. Any advice or suggestion is appreciated.

we want to embed the part of html in to portlet at run time. portlet has a single navigation parameter defined (for run time)
so for example, i write a jsr portlet and then I drag the portlet from resource catalog (composer) on to the webcenter page during run time. and then we would pass
www.xyz.com/index.html as a value of navigation parameter to the portlet. and portlet would consume this index.html.
problem is what is the attribute within portlet which would get binded and finally consume the index.html at run time ? is it
src = .......... ???
is it file = ......... ??
is it url = ........... ??
what is it ?
we are not using UCM so entire Content Presenter taskflows is useless for us
if it is say src = ... attribute, then we were not able to PASS the index.html TO src attribute as Navig Param at run time.
remember, even if we able to pass index.html to portlet .............. then we do not want portlet to show index.html URL but rather would want to show the content of index.html (which is "Hello There, Greetings from the server") to show.

Conditionally displaying a portlet based on parameter?

Hi, I've been looking for a way to show or hide on a page a portlet (the standard Oracle search one, but it could be anything else) depending on whether a parameter is set to 0 or 1. So far the only "solution" I've found is to instead have two copies of the page, one with and one without the portlet in question, but obviously this scales very badly and is a bad idea from a maintenance POV.
Is there a clean way to do something like this?
Thanks,
Cedric

Yes, You can do it .. but it is little tricky. We have done something like this.
First, you may know that all portlets are rendered by PPE , so we can not pass parameters to PPE to display particular portlets based on parameter.
Instead, with in that Portlet, If the parameter is "N" then don't display any HTML from that portlet. Hope you know How to Pass page parameters to Portlets.
Other way to implement this is by Portal Groups and granting access to those portlets,
Still , if you are not convinced you can have a look at Portlet SecurityManager Class..
Thanks

Display HTML page in portlet

I want to let my users place a file in a certian content area and then have a portlet display that content. Any ideas? Where can I start?

you can reference the file by using the folder name followed by the file name. You can point to the url either by adding an html portlet to your page and plugging in a anchor pointing to it or add a url item to a folder with the url of the file. Then render this folder as a portlet and plug it into your page. There are several other methods also depending on the exact results you are looking for.
Hope this helps

Html Portlet links displaying in another portlet on the same page

I have seen similar posts but no detailed explaination of how this is done.
I have an html portlet with links whose content I would like to display in an inline rendering portlet on the same portal page. How can I pass the link url from the html portlet to the inline rendering portlet?
Thanks,
Robyn

If your environment is fairly static, you can handle this easily.
The link in your HTML portlet must refer to the page URL of the portal page on which the HTML portlet resides (which changes from portal page to portal page), to which you need to append the parameter that your "inline" portlet (under which I'm not sure what you mean) reads:
<a href="http://<portal_page_url>&my_param=value">click here</a>Is this close to what you're willing to do?

How to display current user using HTML portlet

Hello,
Is it possible to show any text such as Greeting, Current User (ex, Hello, Kevin) using HTML portlet. Can I use <oracle></oracle> tags to get the current user from the API?
Please suggest me.
Thanks,
Satish

Thanks for your suggestion. There is also another way for this:
In a Portal text field (CMS item) you can type
#USER# to display the username of the authentificated user or
#USER.FULLNAME# to display the full name.
Thanks,
Satish

Display header of HTML Portlet

OS: Windows 2000 5.00.2195 SP1
Portal: 3.0.9
I create a new page, and add a HTML portlet to it. Then I edit the page (via 'edit page') and choose not to display the HTML portlet header. This works perfectly.
But how can I show the header again? There is no customize link available anymore, and via 'customize' of the page I see that the header is already displayed.
Can anyone please help me with this? Thanks in advance!

The best way to do this is to simply use the "Edit Defaults" link for your given HTML Portlet (this is displayed when you edit or customize the portal page in question.) In the "Edit Defaults" customization screen for the HTML portlet you can either enable or disable the display of the portlet header for your HTML portlet.
You'll always be able to access the "Edit Defaults" link for your HTML portlet from the edit or customize screens for the portal page.

Harry

Html portlet to display Flash - Problem

Hi
I have created a HTML Portlet ,and the html consists of one flash (swf file).
Iam running that portlet on weblogic 9.2.
But the flash is not displaying in the browser.
Please Suggest
Srinivas

Thanks for your help. I am trying to do it but it's still not working.
Check this out, just by glancing at the below code, do you think that flash is able to read it? I read in the help that it's only capable of a few tags. Basically I am trying to put this code into a page to display:
<object type="application/x-shockwave-flash" width="400" height="300" data="http://vimeo.com/hubnut/?user_id=matttstubbs&color=00adef&background=000000&fullscreen=1&s lideshow=0&stream=videos&id=&server=vimeo.com"> <param name="quality" value="best" /> <param name="allowfullscreen" value="true" /> <param name="allowscriptaccess" value="always" /> <param name="scale" value="showAll" /> <param name="movie" value="http://vimeo.com/hubnut/?user_id=matttstubbs&color=00adef&background=000000&fullscreen=1&s lideshow=0&stream=videos&id=&server=vimeo.com" /></object><br /><br />I put <a href="http://vimeo.com/matttstubbs/videos">videos I create</a> on Vimeo. You can see <a href="http://vimeo.com/matttstubbs">my profile</a>.
Thanks.

Conditional display in a SQL-Report/Report Region

Hi,
here I have an example for "Conditional display in a SQL-Report/Report Region". I figured it out in Firefox 3.6.2 using Firebug as development tool on Apex 3.2.1.00.12.
First you have to put the following javascript code in the Page HTML-Header:
<script type="text/javascript">

</script>
Maybe you have to modify the "vd_getBody" function. I'm searching the table cell with having the class "t10data". When you use another theme, there's maybe another class used.
Second is, that you set an static id for your report region. I prefer this structure:
R<app-id><page-id><seq> (Raaaaappppsss) e.g. R094260001010.
First example is to turn off the onMouse-Effect. Maybe on the first or last column definition you put this code in the "HTML-Expression" area:
<script>ex_conditional_tr('R094260001010', #ROWNUM#);</script>#ID#This will call the example function ex_conditional_tr with the parameter
a) the region id
b) the rownum (as oracle always starts with 1 this is the first data row [rownum=0 is the table header row])
Second example is the conditional formatting of a table cell. Put this in the HML-Expression area:
<script>ex_conditional_td('R094260001010', #ROWNUM#, #COLNUM#-1);</script>#ENAME#This will call the example function ex_conditional_tr with the parameter
a) the region id
b) the rownum
c) the cellnum (here we have to subtract 1 to get the "real" cell index)
The "ex_conditional" functions are just a representation of how to get the row or cell node.
Hope this help a bit.
Tom

I would use a CASE statement in the select....
each CASE would be an img src tag for a different button if the button is an image.
does that make sense? I can include an example if you would like...

Problems with Conditional Display and Read Only

Hi Everybody,
I have a form to Add/ Modify Table Info.
I have column which stores numeric value (like no. of purchases, no.of returns etc.,) and I have a text field with this Database column as Source.
In some cases the value is a foreign key (Id of the Owner, Buyer etc.,) to another table. In such cases, I want to display a select list containing people information. Is that possible?
This is what I did to achieve that
I added a select list with info from second Table. Made both the text field and the select list to conditional display and conditional read only.
My understanding is that When an item is made read only it should not be saved to the Database.
But while Updating I am getting the following Error
ORA-06550: line 1, column 130: PL/SQL: ORA-00957: duplicate column name ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored.
Any can anybody help me out on this?
Thanks
Nimmi

My understanding is that When an item is made read only it should not be saved to the Database
No, all page items with a Source Type of "Database Column" will be used by the Automatic DML process to insert/update the database. Form inputs with the "disabled" HTML attribute set are not POSTed to the server.
Try to create 2 items, one Select List and other Text Field but setup their conditions such that only one of them is rendered on the page at any given time. That might work.

How to display HTML file in a region

I am implementing a portal Application

How can i set the page such that when the page is browsed the welcome.html
file will be displayed (browsed)in region2

Hi,
It's quite simple - I will a show a very simple example that will give you an idea :-
1. Create a simple HTML Page ( I have created Sandeep.html ) & put this HTML code:-
<HTML>
<BODY>
This is my First Test Page.
</BODY>
</HTML>
2. Copy the file to your $ORACLE_MIDTIER_HOME/Apache/Apache/htdocs
3. Check if you can access the file :- http://your_server:port/Sandeep.html
You should see the HTML Page.
4. Now, login to Portal & create a Page.
5. Add the HTML Portlet to your Page.
6. Edit teh HTML Portlet and add this code :-
<IFRAME SRC="http://your_server:port/Sandeep.html">
</IFRAME>
7. That's it ! - the Page Sandeep.html is displayed on the Portal Page itself !
Regards,
Sandeep

Need help with conditional display

I found a older thread (704012) that explains how to conditionally display a link using style. Which is what I want to do. The part I'm having trouble with is that part of the instructions say to put
class="row_has_values_#HAS_VALUES#"
in the Link Attributes which I have done. I also have a column in the report called HAS_VALUES and I'm properly populating it in my select. I know because I left it displayed while I'm testing. I can run the report and I have Y's and N's showing up in that column but the conditional part does not work. When I look at the page source (below) I see that in the html the #HAS_VALUES# has not been replaced by the actual Y or N. I think that's where I'm having trouble? I think it might work if there was a Y or N in that but I don't understand why that didn't happen.
<tr class="odd"><td headers="LINK"><a href="f?p=125:3:12628966088981::NO::P3_PROGRAM_KEY:2" class="row_has_values_#HAS_VALUES#"><img src="/i/e2.gif" border="0"></a></td><td align="left"

I've continued to snoop around and see lots of posts on conditional display in reports. Common desire I guess. I saw some stuff that I interpreted to suggest that what I'm trying to do may not work in interactive reports, only in classic reports. Does that sound familiar?
That would certainly apply to anything template-related. However there have been enhancements to IRs (like adding HTML Expressions) that might supersede information in older posts. If you provide a link to the sources you've found and the APEX version you're using someone will be able to confirm whether that information is relevant.
Many other posts on doing things conditionally in reports seemed to lean towards "selecting" the html based on data values and then just letting that get put in the report column. That looks promising but sure is a bit ugly. I've very little apex experience but lots of mod pl/sql and that sort of solution was pretty common when I did stuff with it. I saw a little suggesting using templates as a solution but I'll confess to not understanding it at all.
As I pointed out in the original thread, if the conditional display of the link is in any way security related then CSS or JS/jQuery methods are not acceptable. If the user is not supposed to be able to click the link or see any data contained in it, then you have to use a method that ensures that the link element never reaches the browser.
Hard-coding the link HTML in the report query is the common approach, but is as you say a bit ugly. Using a custom report template (my favourite APEX subject) enables clean separation of the report query, conditional logic and HTML structure. If you know HTML then you're advised to get familiar with using templates in APEX. You'll find this a major advance on the PL/SQL web toolkit. What is it that you're not understanding about using templates?

How to use Custom Search in Dynamic Page or HTML Portlet ?

Gurus,
1. I have a tab called My Space in the portal web site, where user gets a personalized view of the content.
2. I am using custom attributes and custom item types. I have a custom attribute called 'Location', which is a attribute of custom item types.
3. I have 2 pages - News and Events.
4. All the content in News and Events page is tagged by the attribute 'Location'.
5. The requirement is to let the user search the News and Events by Location.
6. To achieve this I used the Custom Search portlet and the user can select the attribute Location and see the resultant News and Event items by location in the Search portlet.
7. The requirement is to present the News items and Event items in separate regions on the page and show only the first 5 News and Event items in the result and show a More link which would guide the user to rest of the News and Event items.
8. Eventually there may be more content other than News and Events tagged by location. If so, the requirement is to create a new region and display the new content.
9. How would I do this using custom search ? I was thinking if there is anyway I could use the custom search api (where can i find it ?) in the HTML portlet or Dynamic page and submit the result to IFRAMES in each region and show the output ?
Pls advise.
Thanx a bunch.

I would suggest that you use two custom search portlets; one for the news items and one for the events items. Switch the custom search portlets to "AutoQuery" mode and add the relevant criteria. On the results display tab of the the "edit defaults" screen, choose to show just 5 items.
To add a link to show the user mode results, I'd create two new pages that have just a single custom search portlet on it that is customised to show more of the results and maybe has the pagination links enabled.
Then I'd add two "Page Link" items underneath the two news and events portlets on the first page in an item region.
I'm sure there are other ways of doing this as well. Hope that helps to get you started.

Use of basic SQL functions in conditional display of an item

I'm trying to use the following to conditionally display an item.
Condition Type is set to: "Value of Item in Expression 1 = Expression 2"
Expression 1: "sign ( instr ( :column_name, '1*' ) )"
Expression 2: "1"
The :column_name column contains an asterisk delimited list of numbers. I wish to hide or show an item based on whether a specific number is in the list. When I run the page, the item never shows up. For testing purposes, I am using HTP.P to display not only the entire value of :column_name, but also the resulting value from the "sign(instr(... ))" code. The results of the HTP.P debugging show that the expression does indeed return a value of 1, but the item is still not displaying.
Any thoughts? I'm relatively new to HTML DB, so there may be some obvious thing I am missing.

Try setting the Condition Type to "PL/SQL Expression" and use:
sign ( instr ( :column_name, '1*' ) ) = 1
The express must evaluate to TRUE for the item to display. See the "Conditions Available in Oracle HTML DB" section in the Oracle HTML DB User's Guide.

Conditional display column in report

Hi,
If we have a single row report of 30 columns, and I want to display only the one with any values but null and hide the null ones, Is there a way to do it?
It's the same issue discussed in this thread conditional display column in report
thanks,
Fadi.

Samara - I suspect there are a few ways to do this, but none obvious or very easy as far as I can see.
You can create dynamic SQL (as Arie and others have suggested) to only include the columns that are not null.
You can build and output the HTML directly to the page, choosing only to include the values that are not null.
You can create a set of conditions that you can apply to the report columns. A very crude example might be 30 hidden page items like 'SHOW_COL1' etc. (not great, I know), or perhaps you could set a hidden page item to a value like '01:02:03:'etc., with the number only being included if the value is not null (so that col3 being null gives you '01:02::04'etc.), so that the condition for each column is 'Text in expr 1 in contained in Item in expr 2', where expr 1 is '01' for column 1 etc.
Sorry, that is a very contrived example, but it's just to illustrate that there's generally a way of doing pretty much anything in APEX. You might create your item containing the comparison expression by requerying the data in this kind of way:
SELECT NVL2(column1, '01', '') || ':' || NVL2(column2, '02', '') || ':' etc.
FROM table
WHERE condition
However, wanting to create a single-row report with nulls hidden makes we wonder what you're actually trying to achieve and whether there's a better way? Could you use a series of page items, for example?

Application Level Function for Conditional Display

I need to hide a field on Print Preview if it is null. I currently have the following PL/SQL Expression Condition:
:P305_DEPT IS NOT NULL AND v('PRINTER_FRIENDLY') <> 'YES'
It works great; now I need to do this for a lot more fields within my application. Is there a way to call a PL/SQL process defined in HTML DB, passing it the current item value, or some other way to save myself some typing?
I've tried various combinations of shortcuts, substitution strings, application processes, etc. and can't seem to get the right combination.
I'm hoping you have a cool solution, or some other ideas I can try out.
Thanks!
Chaunaci

Hi Raj,
All of this came up because we have several data items displayed above each report page, which allow the user to enter filter criteria. When the page is displayed in Print Friendly mode, the Select Lists display as blanks when null, but Text Boxes display as [] when null.
Our QAs have asked us to make all of the filter fields consistent in appearance in Print Friendly mode. The work-around solution is to hide the filter fields that are null when in Print Friendly mode. Therefore, we came up with the following PL/SQL Expression to use in the Conditional Display:
:P305_DEPT IS NOT NULL AND v('PRINTER_FRIENDLY') <> 'YES'
Because I will need to add the above conditional statement to many items, I was hoping to create and call an HTML DB application-level process and pass the current item value in, so my conditional display logic would look something like...
HIDE_NULL_ON_PRINT(:P305_DEPT).
When I was doing some additional testing last night, I realized my boolean logic needed to be tweaked, and it would be nice to tweak it in just one place, rather than on every field's conditional display.
I currently have it working by putting the IS NOT NULL AND v('PRINTER_FRIENDLY') <> 'YES' into an application substitution string, so my conditional logic shows as:
:P305_DEPT &HIDE_NULL_FOR_PRINT.
In trying to determine if this was the best solution, I need answers to the following issues:
1. Is there a way to generically reference the current item in the conditional display logic? I currently type in the specific item name (ex: :P305_DEPT), but it would be nice if instead I could just say &CURRENT_ITEM_NAME. (or something similar).
2. Can I create an application-level process, pass a parameter into it (the current item), and have it return a value that can be evaluated by my conditional logic display?
Thanks so much for your quick responses to this and all my previous posts. It is wonderful to be able to post a problem at the end of the day, and come in to a solution in the morning!
