Hello,
The APEX_ITEM package is there so you can programatically create your items on your page.
You can use that in a PL/SQL Region or directly in your report (in your select statement).
- In a PLSQL Region you would do:
htp.p(APEX_ITEM.TEXT(...));
- In SQL you would do
SELECT APEX_ITEM.TEXT(...) as t1 ...

Populating apex item checkbox in report row based on database value

Hi All
I am looking for help setting an apex item checkbox to 'checked' depending on a record exisiting in a database and I would appreciate a little guidance.
At the moment I have a report which looks a bit like this
SELECT licence_user_identifier,
description,
licence_name,
apex_item.checkbox(22,licence_id)
FROM TABLE(SOL_LICENCE.F_RETRIEVE_ORG_LICENCES ( 121 ));
4 columns and the last column is a checkbox called 'assign' and is used to assign the selected licence to a user(who is already displayed on the page in another table). There is save button which when clicked saves a record to the database if the checkbox is selected.
However when the page is displayed the checkbox should be prepopulated/checked if there is a record in the database saying that the licence is assigned to the current user. I have created a page process to try and collect this information and populate the checkboxes on load - before header. However I am having difficulty referencing the apex_application item the corresponds to each row because when I use the FOR i IN 1 .. apex_application.g_f22.COUNT LOOP it only selects the item if it is checked. Can anyone point me in the right direction?
here is the process I have to populate the checkboxes, it is not getting to my flow.debug as there are no selected checkboxes:-(
DECLARE
v_count     NUMBER;
CURSOR getlicences (p_co_id so05.co_id%TYPE)
     IS
SELECT     licence_id
FROM     so05_cust_org_licences
WHERE     co_id = p_co_id;
BEGIN
     IF :p9_co_id IS NOT NULL
     THEN
          FOR each_rec IN getlicences (:p9_co_id)
          LOOP
               --check if a record exists
               SELECT     COUNT ( * )
               INTO     v_count
               FROM     so05_cust_org_licences
               WHERE     co_id = :p9_co_id AND licence_id = each_rec.licence_id;
--if the record exists populate the checkbox
               IF v_count > 0
               THEN
                    FOR i IN 1 .. apex_application.g_f22.COUNT
                    LOOP
wwv_flow.debug ('bbbbbbbbbbccccccccccandwearein' || v_count);
                         IF apex_application.g_f22 (i) = each_rec.licence_id
                         THEN
                              apex_application.g_f22 (i) := 1;
                         END IF;
                    END LOOP;
               END IF;
          END LOOP;
     END IF;
END;

Hi,
Sorry my mistake. You can use the above link only to solve this problem, for this you have to use a hidden column to which you will assign 'Y' or 'N' as mentioned in that post.
using that hidden column value you can fire your query accordingly.
let's say your hidden column is f01 and checkbox column is f02 and the id column is f03, you can do like this
create a process before your update process like this
BEGIN
    -- Reset the hidden ADMIN_USER flag for all visible records to N
    -- Note: g_f01 maps to the hidden ADMIN_USER column
    FOR ii IN 1 .. APEX_Application.g_f01.COUNT
    LOOP
        APEX_Application.g_f01(ii) := 'N';
    END LOOP;
    -- Set the hidden ADMIN_USER flag for those records where the
    -- checkbox has been set by the user to Y
    -- Note: g_f02 is the checkbox column ADMIN_USER_CHECKBOX
    FOR ii IN 1 .. APEX_Application.g_f02.COUNT
    LOOP
        APEX_Application.g_f01(APEX_Application.g_f02(ii)) := 'Y';
    END LOOP;
END;then write a new process positioning after above process
if apex_application.g_f01 = 'Y' then
your update query using id column (f03)
else
your delete query using that id column (f03)
end if;hope this helps you.
Thanks

SQL Report query with condition (multiple parameters) in apex item?

Hello all,
I have a little problem and can't find a solution.
I need to create reports based on a SQL query or I.R. Nothing hard there.
Then I need to add the WHERE clause dynamically with javascript from an Apex item.
Again not very hard. I defined an Apex item, set my query like this "SELECT * FROM MYTAB WHERE COL1 = :P1_SEARCH" and then I call the page setting the P1_SEARCH value. For instance COL1 is rowid. It works fine.
But here is my problem. Let's consider that P1_SEARCH will contain several rowids and that I don't know the number of those values,
(no I won't create a lot of items and build a query with so many OR!), I would like sotheming like "SELECT * FROM MYTAB WHERE ROWID IN (:P1_SEARCH) with something like : ROWID1,ROWID2 in P1_SEARCH.
I also tried : 'ROWID1,ROWID2' and 'ROWID1','ROWID2'
but I can't get anything else than filter error. It works with IN with one value but as soon as there are two values or more, it seems than Apex can't read the string.
How could I do that, please?
Thanks for your help.

For an IR—and improved security avoiding the risk of SQL Injection—use a <a href="http://download.oracle.com/docs/cd/E17556_01/doc/apirefs.40/e15519/apex_collection.htm#CACFAICJ">collection</a> containing the values in a column instead of a CSV list:
{code}
SELECT * FROM MYTAB WHERE ROWID IN (SELECT c001 FROM apex_collections WHERE collection_name = 'P1_SEARCH')
{code}

How to create read only Apex items

Hi,
I'm creating a report using Apex items to display the result values inside editable text boxes. They are then referred by using APEX_APPLICATION.G_F02 etc.
My requirement is to make the last row of this report (the values for "Total") as non editable or read only. Can anybody help me with the code that i would need to add in the query? The query goes something like this:
apex_item.text(7, TO_CHAR(nvl(year_4,0),'999,999,999'), 12, 12, 'style="text-align:right;font-weight:bold"',ROWNUM) "YEAR_4", ..

Surprising. I would have expected there to be a CSS style to disable a form item.
Depending on your reasons for wanting to use APEX_ITEM, you could:
Select your required value as part of the query (without using apex_item.)
Visit your report attributes, then the attributes for your specific column.
Change the column type to text field.
Add readonly=true into the item attributes.

How to populate values in Apex item

Hi,
I am using apex collection item to capture data my requirement is to calculate data using the apex item
This requirement is like this. I am using a SQL query like this
select
wwv_flow_item.TEXT(1,NULL,20,10) "A",
wwv_flow_item.TEXT(2,NULL,20,10) "B",
wwv_flow_item.TEXT(4,NULL,20,10) "C"
from dual
There 3 text boxes are generated in the window when i enter 3 in A and 2 in B it must give me a sum value in C as 5
this has to be done dynamicall as end user key in values this can be done using java script or any other method please suggest
Thanks
Sudhir.

Hello Sudhir,
>> If there are multiple text box …
If there are multiple text boxes, you need to allocate each a unique ID. The easiest is to use the substitution string #ROWNUM#. The code should look similar to the following:
select empno,
apex_item.TEXT(1,null,20,10,'onchange="addItems(this);"','A'||'#ROWNUM#') "A",
apex_item.TEXT(2,null,20,10,'onchange="addItems(this);"','B'||'#ROWNUM#') "B",
apex_item.TEXT(3,null,20,10,'onchange="addItems(this);"','C'||'#ROWNUM#') "C"
from empBecause we are in a multi-row environment, we need to pass the line number we are on, into the JavaScript function, hence the use of ‘this’.
In the JavaScript function, we first need to determine the line number we are on, and then use it to perform the calculation. The code can look similar to the following:
<script type="text/javascript">
function addItems(pThis) {
/* extract rownum */
var line_no = pThis.id.substr(1);
$x('C'+line_no).value = parseInt($v('A'+line_no)) + parseInt($v('B'+line_no));
</script>Regards,
Arie.

Passing values to APEX items from external site

All,
Is it possible to pass values to APEX page items from an external web site?
For example, I have an external web site where users type in a username and password into fields. When they click the 'log-in' button in the external site, I would like to have those values passed to the APEX log-in page. If possible, I would like to have the APEX log-in occur 'invisibly' and the user taken directly to the home page of the app. If that's not possible, it would be nice to simply have the 'user name' and 'password' fields filled in on the APEX side.
I'm using APEX 3.0.
Thanks in advance for any help!
Alex

Hello Alex,
>> Is it possible to pass values to APEX page items from an external web site?
The general answer is yes. You can use the f?p syntax to set the value of any APEX item - http://download-uk.oracle.com/docs/cd/B32472_01/doc/appdev.300/b32471/concept.htm#sthref185 .
In your specific example, the main question should be is it wise? The mere fact that you are using a login process suggests you have something to protect in your application. The f?p syntax uses a plain text for the items’ value, which means that the user name and password will be completely exposed.

And like I said I basically want to put APEX text items inside Oracle HTMLAPEX can only handle items [created declaratively through the App Builder|http://download.oracle.com/docs/cd/E14373_01/appdev.32/e11838/app_comp.htm#CHDGFCGB] or programmatically using the [APEX_ITEM API|http://download.oracle.com/docs/cd/E14373_01/apirefs.32/e13369/apex_item.htm#CACEEEJE].
It looks like you want to create a Login Page. This is a standard APEX page type that can be created from the application home page: click Create Page >, select Login Page, and complete the wizard. The look and feel of this page is controlled by standard APEX [page layout techniques|http://download.oracle.com/docs/cd/E14373_01/appdev.32/e11838/ui.htm#BABJIECG], and the [themes, templates and CSS|http://download.oracle.com/docs/cd/E14373_01/appdev.32/e11838/themes.htm#CJABAEIE] applied. To achieve the required appearance in APEX, page and region templates and CSS can be modified to contain the necessary HTML and properties.
Try experimenting a bit with the above. If you hit problems, raise new threads dealing with specific, discrete issues...

I am looking to enter numbers in the NOT IN clause like '123,234,...'
I have a text field item (P62_MRID) where the user can enter IDs for the NOT IN clause. So for example, 13578,182. If the user enters one number it works fine. If the user enters 2 numbers with a comma (13578,182) then I get this error when the computation is run:
ORA-01722: invalid number
So substituting 13578,182 for P62_MRID the SQL statement should compute as:
select count(mr.mr_id)
from ds_moriver mr
where mr.approved = 0 OR mr.approved IS NULL
and mr.mr_id NOT IN (13578,182)
Why am I getting the error, 'ORA-01722: invalid number'?
Thanks in advance!

Glad to help. Don't know how long you've been using APEX, but thought I'd caution you against "going wild" with the item substitution syntax. In general, if you can do it with bind variable syntax, that's better. The use of item substitution syntax can contribute to SQL injection attacks. But, if you have suitable control over the contents of the items being substituted, the risk is mitigated. Just don't create an APEX process like this:
begin
&P10_TEXT_DIRECTLY_FROM_USER.
end;
That'll get you into trouble.

Change "name" propertie of a apex item

Hi all,
I´m trying to change some atributes of a select list item, like "name", but the apex put a name like "p_t04", even if i put a (( name="mine" )) in the atributes of form elements, when i check the html source code, the name "p_t04" is in there. Apex set the ID of a item like the name i choose to the item when i create then, but the select NAME=" " <<< that name, cannot be changed??
sry about my english...

Hi Dan..
I need create a multiselect combobox. Is a combobox with checkbox inside. I found some JQuery in google, but to change the normal APEX select-list into the jquery multiselect i need change some properties to call the function. I alread try to create my own combobox, but its hard to populate with DB result and using position absolute after all, the final result is not so good, work, but not like i need it.
I need change the atributes of the apex select list to change in to a multiselect. You think if i change that (if there´s a way to that)) will be a problem??
tnks for help me.

Integrating APEX items into an HTML Login Screen

I've just been presented with an attractive html login screen that our art department has created for our new application. The only problem is that the art department doesn't know a thing about APEX. They've drawn a nice looking screen using several images laid out into tables and even included an html form for the login credentials.<br>
<br>
I'd really like to use as much of their page as possible and I'm close to getting something that at least looks like it might work. I've encapsulated the entire thing into htp.p statements inside of a PL/SQL region on my Login page. I've removed their form elements and placed my own fields using HTMLDB_ITEM.TEXT calls. I also believe that I will be able to read back the values using calls to HTMLDB_APPLICATION.G.Fxx for each of my IDX values. I haven't tested that part yet, but it seems like it should work.<br>
<br>
The part that has me stumped right now is modifying the TEXT item into a PASSWORD item type. I've tried adding type="password" into the attributes parameter and I do see that in the page source, but it's after the default type="text" statement and is therefore ignored. The statement I'm executing for my password field is: <br><br><b>htp.p(htmldb_item.text(22,NULL,30, 100, 'type="password" onkeypress="return submitEnter(this,event)"', 22, 'Password:'));</b><br>
<br>
It doesn't seem like there is much reason to go on if I can't hide the contents of my password field, so I though I should ask for some advice before going too much further.<br>
<br>
Am I missing a better way to override the item type here, or is there a better way to place my login fields at specific locations inside of an existing html document? I can get the fields above, below or next to their page but that looks terrible. I could also break up their page into a top section and a bottom section with my fields in a middle region, but that would also ruin the look of the page.<br>

Hi, Etown88.
You've learned two important lessons:
1. Undocumented features are undocumented for a reason.
2. Never try "tricks" you read in magazines or on the Web unless they also clearly specify how to undo the trick. In fact, you should skip tricks like this: review Lesson 1 above.
The specific "trick" you cite was in Macworld recently and can be found on their web site here and here, the latter under the heading "Make your login window informative".
You'll also note at the end of the second article that it contains a correction: sometimes tricks have typos that can really ruin your day.
The "trick" probably originated as a post on the Mac OS X Hints site since the column was written by Rob Griffiths who runs that site.
To "undo" this, simply specify HostName, which is the default:
defaults write /Library/Preferences/com.apple.loginwindow AdminHostInfo HostName
This is stated in the articles cited above, but one has to realize it as its stated subtly, e.g."• HostName to show the default display"Good luck!
