Dynamic Drop Down & displaying selected results

Hello!
I have been following the DDT image gallery tutorial - and it has been great! But, now I am stuck... What I have done is created an image gallery that displays all my Orchid Flower images. However, now I would like to add a drop down list to the photo gallery where the user can select:
to view orchid by color (data base driven)
view orchid by season(data base driven)
Could someone please point me to a tutorial that I can follow to set this up? Or can you post the code that I would need in order to get this to work?
Thank you!

Hi Cathy,
please back up your current page and replace the following line:
$query_getimages = "SELECT * FROM image_img";
with this code block:
if (empty($_POST['color']) && empty($_POST['season'])) {
$query_getimages = "SELECT * FROM image_img";
else {
if (empty($_POST['color']) && !empty($_POST['season'])) {
$query_getimages = "SELECT * FROM image_img WHERE season = '".$_POST['season']."'";
if (!empty($_POST['color']) && empty($_POST['season'])) {
$query_getimages = "SELECT * FROM image_img WHERE color_id = ".$_POST['color_id']."";
if (!empty($_POST['color']) && !empty($_POST['season'])) {
$query_getimages = "SELECT * FROM image_img WHERE season = '".$_POST['season']."' AND color_id = ".$_POST['color_id']."";
That should work -- does it ??
Please note that such a manual modification of a Dreamweaver recordset might have a drawback :: DW will no longer display it in the Server Behaviours tab later on, and if you would try to add additional e.g. "Dynamic Text" instances based on this recordset, DW will also refuse to do that, as it can´t recognize it any longer. That said, such modifications should always be applied when a page can be considered "feature complete"

Dynamic Drop-down list - selected value can't be cleared ...

1. check out the following code of a dynamic drop down list using cursor :-
DECLARE
     -- DROP-DOWN LIST OF ALL DEPARTMENTS
     TEMPNUMBER NUMBER(2) := 2 ;
-- Because we've to initialize the list
-- at least with 1 item.
CURSOR C_DEPT IS
     SELECT DEPT_ID FROM DEPARTMENT;
BEGIN
     ABORT_QUERY ;
     CLEAR_LIST('DEPTLIST');
     FOR TEMP IN C_DEPT LOOP
     ADD_LIST_ELEMENT( 'DEPTLIST', TEMPNUMBER, TEMP.DEPT_ID, TEMP.DEPT_ID );
     :SRBLOCK.LST := TEMP.DEPTNO;
     -- prev. line set the newly selected value
     TEMPNUMBER := TEMPNUMBER + 1 ;
     END LOOP;
END;
2. problem is as we've to atleast initialize with one list item... that item can't be cleared with CLEAR_LIST.
3. how can i actually clear that and still use cursor. because i've searched forum for this thing and found all those code not working ... for my project ...
4. quick help needed ...

Hi Omar,
I have solution for you
To populating or refreshing the lists you can use
two procedures:
One of them - generic, which can be used for all types of list
Another is specific which contain a SQL statement to retrieve the data for
particular list.
1. Specific procedure:
PROCEDURE GET_DEPARTMENT_LIST
IS
sql_stat VARCHAR2(32767);
ret_code NUMBER;
BEGIN
-- SQL Statement for Drop-down List
-- (must have two columns for label and value - both VARCHAR2)
sql_stat := ' SELECT DEPARTMENT_NAME,TO_CHAR(DEPT_ID)'
||' FROM SCHEMA.DEPARTMENT';
POPULATE_MY_LIST('BLOCK.DEPARTMENT_LIST',sql_stat,ret_code);
END;
2. Generic procedure:
PROCEDURE POPULATE_MY_LIST
(item_name VARCHAR2,
sql_stat VARCHAR2,
out_code OUT NUMBER)
IS
rg_id RECORDGROUP;
rg_name VARCHAR2(100);
ret_code NUMBER;
item_id ITEM;
BEGIN
     item_id := FIND_ITEM(item_name);
     IF ID_NULL(item_id) THEN
          out_code := -1;
          RETURN;
     END IF;
     --Creating Record Group with Unique Name
     rg_name := 'RG_'||SUBSTR(item_name,INSTR(item_name,'.',1)+1,LENGTH(item_name));
     --Checking Record Group Name for existance
     rg_id := FIND_GROUP(rg_name);
     --If Group does exist - delete it
     IF NOT ID_NULL(rg_id) THEN
          DELETE_GROUP(rg_id);
     END IF;
     --Creating Record Group
     rg_id := CREATE_GROUP_FROM_QUERY(rg_name,sql_stat);
ret_code := POPULATE_GROUP(rg_id);
IF (ret_code <> 0) THEN
     out_code := ret_code;
     RETURN;
END IF;
POPULATE_LIST(item_name,rg_id);
IF NOT FORM_SUCCESS THEN
     out_code := -2;
     RETURN;
ELSE
out_code := 0;
END IF;
DELETE_GROUP(rg_id);
END;
Hope it help.

Drop Down Menu selection query for recordset.

I am looking to utilize a dynamic drop down menu to query a recordset...I am using Colfusion to import an MS Access database that contains the following fields: "Model Date", "Name", "Points" and "Target". Each time the database updates, the "Model Date" field contains the date and time the model was run. I have figured out how to create a dynamic drop down using SELECT DISTINCT "model date" and have also figured out how to create the dynamic recordset to be displayed showing the "Name", "Points" and "Target" data.
I want the user to select the "Model Date" from the drop down, hit a submit button and then have the appropriate "Name", "Points" and "Target" data queried and shown below.
The query should take the selection from the "model date" dropdown and then query the "name", "points" and "target" fields for that particular "model date"
I admit my knowledge of SQL and Coldfusion is not the best, but it seems like this is a somewhat simple task and I am just missing one or two pieces of the cog to put it all together.
The database basically looks like this:
Model Date...........Name..........Points........Target
8/1/2010 08:00......John Doe.....1,250.........5.55%
8/1/2010 08:00......Jane Doe.....850............2.35%
8/1/2010 08:00......Bill Smith....11,832........-123.23%
8/2/2010 09:02......John Doe.....1,323.........6.67%
8/2/2010 09:02......Jane Doe.....1,001.........3.21%
8/2/2010 09:02......Bill Smith....10,235........-110.26%
The dropdown will only show the "model dates"
8/1/2010 08:00
8/2/2010 09:02
For example, if 8/1/2010 08:00 was selected from the dropdown, I want the following displayed:
Name..................Points...................Target
John Doe.............1,250....................5.55%
Jane Doe.............850.......................2.35%
Bill Smith............11,832...................-123.23%
Any help or suggestions would be greatly appreciated!!!
Thanks,
Mike

My second paragraph talks about just displaying the filtered data, so I'm assuming that's what you're looking for, but still not quite sure based on what the other responses are.
But I head on anyway -
On your first page, make note of the instance name of your drop down menu, such as "ModelDate". Make sure it's in a Form and set the form action to the page where you want to display your data, set the form action to POST.
On the results page, create a table with cells for each of the data elements you want to display. Create a recordset which you can do in Simple mode. Leave it at select all, and set the filter drop down to the database field which contains your Model Date. In the box to the right, select "=". the next dropdown selct "Form Variable" and the variable name type in the instance name of the drop down on the first page.
I may not have the terminology right, doing it from memory.
From the data bindings tab, expand your recordset and locate each of the database fields you want to display. Drag each one to the table cell on the page where you want it displayed. The table cells have to be in a linear row.
Now, select the table row buy selecting the TR tag in the tags just above the properties panel. In the server behaviors tab, select repeat region and "All Records"
Publish your pages and test!

How do I enable multiple dynamic drop down boxes?

I'm using Windows 2000, Java SDK 2 Standard, Tomcat, Apache, Microsoft Access and Macromedia Dreamweaver Ultradev 4.
With UltraDev I'm trying to create a jsp page that has more than one dynamic drop down box or more than one dynamic select list box. I can show one dynamic object and as many static objects as I need. But when I add a second dynamic drop down box, with a second recordset, the page will only display the first dynamic object and all content following that object will not display.

Here's the code:

How to populate data from dynamic drop down list to the text field

Hi,
I tried to populate data from dynamic drop down list to city field. I would like to concat data from drop down list.When selecting add button to add the item and select item from drop down list, data should be displayed in the text field. However, Please help. I spent alot of time to make it works I am not successful.
Please see the link below.
https://acrobat.com/#d=SCPS0eVi6yz13ENV0cnUdw
Thanks for your help
Cindy

Hi Rosalin,
Loop the hidden table, get the values and populate drop down in each iteration.
DropDownList1.addItem("Text","Value");
You can use one more solution for this scenario. If it is a matter of 2,3 dropdowns, put three dropDowns in the form layout and give seperate static data binding to them. At run time make the dropDowns hide/visible as per the requirement.
Hope this helps.
Thanks & Regards,

Dynamic drop down list in Adobe forms

I have created a drop down list using enumerated drop down list from webdynpro native tab and binded in the object palette by giving $record.sap-vhlist.DESCR\.DATA\.FIELD.item[]* in the list items dynamically.DESCR is the field in the internal table into which i fetched data from the database table .I have written this code in a BADI.I dont know whether my form's display type is activex or native? I am not getting any values in the drop down list.can anybody please tell me what might be missing and how should i know whether my form is ActiveX or Native?
My form is called from portal so i have used BADI to connect portal to form

Hi sarang,
I have done a dynamic drop down list in which DESCR field comes from database table and pops into the drop down dynamically. I was working for a PCR scenario so the adobe form was called from portal.I will tell u all the required steps.It might work for u as it is working for me:
1.In the form:
I used two elements from library first is a "ENUMERATED DROP DOWN LIST NO SELECT" from web-dynpro native tab and second is "ISR_TEXT DISPLAY INVISIBLE ON EDIT MODE" from ISR controls tab.Place them one on other inthe form.
For drop down list the setting are:
     In object, field tab click on list items there in ITEMS put :$record.sap-vhlist.DESCR\.DATA\.FIELD.item[*].in ITEMS TEXT write text in ITEMS KEY write key.
     In binding,in default binding put $record.DESCR.DATA[*].FIELD.
For text element the settings are:
     In binding,default binding put Normal.
     when we select ISR_TEXT DISPLAY INVISIBLE ON EDIT MODE it automatically comes with calculated read only int he value tab.so open script editor and place the below code:
$record.DESCR.DATA.FIELD (in calculate).
2.Now the code in BADI is as follows:
In BADI we have to write the code for drop down list in the METHOD "SCENARIO_SET_ADDITIONAL_VALUES"
As i didnt change the standard BADI i added an enhancement spot in which i wrote a function module which fills ADDITIONAL_DATA. and the below code fills the ADDITIONAL_DATA .
DATA: t_t572b TYPE STANDARD TABLE OF t572b WITH HEADER LINE,
        t_t554t TYPE STANDARD TABLE OF t554t WITH HEADER LINE.
SELECT * FROM t572b INTO TABLE t_t572b WHERE sprsl EQ 'E'.
CLEAR ls_additional_data-fieldindex.
LOOP AT t_t572b.
    ADD 1 TO ls_additional_data-fieldindex.
    ls_additional_data-fieldname ='DESCR_KEY'.
    ls_additional_data-fieldvalue = t_t572b-descd.
    APPEND ls_additional_data TO additional_data.
    ls_additional_data-fieldname ='DESCR_LABEL'.
    ls_additional_data-fieldvalue = t_t572b-descr.
    APPEND ls_additional_data TO additional_data.
    CLEAR t_t572b.
ENDLOOP.
For DESCR field the we have to declare DESCR_KEY and DESCR_LABEL in the place holders for key values and palce holders for default values in characteristics tab(where all the fields for the form are defined) of ur respective scenario.(where ur pcr scenario is defined)
Hope ur problem got resolved.
Please let me know if any doubts.
If ur form is not called from portal and u want a dynamic drop down list the difference is put a data drop down list and in object, field tab click on list items there in ITEMS select the field into which u populated the data from the database table (this code shud be written in code Initialization in the respective interface) and in ITEMS TEXT put $ in ITEMS KEY put $.and in binding as we normally do bind it to the respective field in which the data is populated from database table.
It should work.

Iu2019m a new in JavaScript. I thing a missing something in JavaScript, wenn I click add-Button
Please let me know what is missing or send me an exampel.

Hi Chintan,
Thank you for your help.
I will try to explain more clearly my problem .
In my case, my form will be used in ABAP system without any web dynpro applicatoin . forms are send by mail and retrieve by mail in SAP .
I define a PDF forms in the ABAP stack of SAP . in the form i create a table subforms , number of rows depend on what is store on the database.
In the fact, my field is defined as dropdownlist box and value are link to the content of the interface attributes .
For thr first row that works fine but when i add a line, the content is not populate automaticaly, and i can' t open the dropdownlist.
When user receive the forms, he can add lines to the table while it's define as dynamic. My problem is that on NEW LINE the dropdownlist box is empty.
How can i solved this issue ?
Tanks

Dynamic Drop-Down Menu Solution

Hi All,
After spending a lot of time trying to find a good solution for a dynamic drop-down menu, I end up writing my own.
The solution is for a list of items, having ITEM as the primary key of the table and ITEMDESCRIPTION as the list of options for the user to select.
The steps are:
1) JavaBean to return a ResultSet;
2) A custom tag to build a HTML SELECT;
3) A .tld file to declare the custom tag;
4) web.xml where the custom tag mapping resides;
4) A JSP to illustrate how to call the custom tag;
Hoping this will save lots of time to others
Cheers

This is a very helpful execellent sample code.
However, If I'm using Model-View-Control approach, then what's the way of applying these codes
to each indivisual file? Say, I have 20 files and only 4 of the 20 need to be treated as they like
to have drop down menu in particular column(s)??? How could the custom tag be applied as the
controller tells the view to present these special treat? or it is not possible (I have to treat each
file, filtered by controller -- one by one as it encounters the special need)?
Thx, Tzae

--urgent Can I use table data to create a dynamic drop down menu?

Hi,
I am asked to investigate the possibility of using APEX to create a table driven dynamic drop down menu? The deadline is tomorrow but I have spent quite a bit of time but still have not any clue. Can any one have such experience to point me a way to focus on?
Many thanks.
Jennifer

Thanks you very much for the help Kevin.
Currently my company is using htp.p style to create web app and using the dynamic menu in a similar way as you explained. Now they want to move to Apex and still keep dynamic menu functionality. After reading your response and research I have done I think I can embed it into Apex application by creating the similar table and PL/SQL package and let Apex to call the PL/SQL package when the application is first called. However may I ask you a question about how to call such pl/sql procedure in Apex? .
The current application has the following URL, from which the procedure pkg_main.print_menu is called and html home page with dynamic menu is displayed.
Http://app server:1234/pls/applicationname/pkg_main.print_menu?p_new_window=N
BUT what about the Apex? The Apex URL format is like the following, where 11563 and 1 is application id and page number. Assume that 1 is home page, but HOW the procedure is called, from WHERE?
http://apex.oracle.com/pls/apex/f?p=11563:1:3397731373043366363

How can I get a drop-down list selection also be selected in another field with the same list but a different name?

I have a street address and a billing address. A question is posed with a checkbox — "Is the billing address the same as the street address?" If Yes is checked, the street address automatically fills the billing fields. If No is checked, the user must fill in new information. In both the street address and billing addres, the State field is a drop-down list. How can I get the drop-down list selection in the street address State also be selected in drop-down list for the billing address State?

Has anyone done this?

How do I make a drop down menu selection show up in another web page?

What I am trying to accomplish is this. I have a page with various drop down menu selections that I want to transfer the selection to a secured web page. What happens now is once the selection is made it goes to the secure page but then the user has to again select the choice again. Is there way to keep the selection chosen in the linked page?

You can set the "selected" value in the second page based on the input from the first page.
Ignor the language referance used below for the example and simple use the concept with your desired language.
Second Page form:
<form id="form1" name="form1" method="post" action="">
<select name="testing" id="testing">
<option value="Value 1" <% if ( Passed values == Value 1 ) { %>selected="selected"<% } %>>Lable 1</option>
<option value="Value 2" <% if ( Passed values == Value 2 ) { %>selected="selected"<% } %>>Lable 2</option>
</select>
