Oracle Apex pass item value from one page to another - oracle-apex

I am just looking into Apex and have set up two pages:
- one with an entry text box called SEARCH_STRING;
- the second page is a report based on the entry made the first page with a field called P2_X.
I want to pass the value of the string to the second page but it does not appear.
On the first page, I have configured the button so it will set P2_X with SEARCH_STRING, (actually listed as &SEARCH_STRING) but whatever text I type in, nothing appears in P2_X.
This is such a straightforward operation, I know I'm missing something fundamental but I can't see what it is

Check the configuration of you button, there must be "&SEARCH_STRING." with a dot.
Check the source of the field P2_X.
Check the "Clear Cache" field of you button, it must be empty.

How to pass data values between pages

I'm getting and showing data from database. I was created button which one redirects to another page and fill form data. Button redirects to another this application page and sets items (names, values). If I set static value - it's works. But how I can pass data from columns (MAX_PHOTOS, MAX_PHOTO_SIZE) using Page Designer?
When creating a link, you have options.
http://prntscr.com/t70l76
You type in the Page number, and then below that you set items. You can just click the buttons next to the lines and it shows you the items on the target page and the items on the source page, you select those and thats that.
If you are writting them in yourself, then you can do &P1_ITEM. Dont forget the . at the end. This also works for other uses where you need to reference page items. But know that those values must be submitted in order for them to be used.

Oracle APEX - Transferring page item value from one page to another

Not sure what am I doing wrong and need help to diagnose the issue.
I have an apex page with an IG on it with radiobutton selection column, allowing the user to select only one row at a time.
On row select I use javascript to grab the ID of the selected row and then use Execute PL/SQL
NULL;
in order to store the value into the session state of P2_ID.
I also have a button on the page that has another page as a target - page 3, and I need to get my P2_ID value to that page.
So I set the page item of a target page - P3_ID ro &P2_ID. in a Link Builder - target pop up window. Along with that I pass another page item P2_TEST, which has a static value.
Now when I get to page 3, I do not see P3_ID in the session state while I do see P3_TEST and it does have a value, but P3_ID is not even listed... What am I doing wrong here?
How about this: instead of executing NULL; when pushing the button, SUBMIT (submit will certainly store values into session state). Create a branch which takes you to page 3; among branch properties, you'll find an option to set P3_ID to P2_ID

Oracle APEX, create & save (insert) from Interactive Report page to DML Form

Need a help in understand underline logic here. I have created a simple APEX application. First page shows the table details and via a "Create" button "Interactive Search" region, directs to a form page. Now form page consists of "Save" and "Insert" buttons in correct regions. So whole app works. When I press "Create" from 1st page to 2nd, "Save" button is invisible and when I click the edit icon on the table of 1st page, "Create" button is invisible in 2nd. App works accordingly, but could not figure out what setting enable this set-up even though I was able to make it work.
1st Page : Interactive Report Page. 2nd Page : DML Form. Built the app from blank pages.
Could any of you explain how it works?
When you click the Create button on the Interactive Report page, it takes you to the Form page in insert mode, i.e. it allows you to enter a new row into the table. Therefore, the Form page has the Create (and the Cancel) button.
On the other hand, when you click the Edit button on the Interactive Report, it takes you to the same Form page, but this time in edit mode which enables you to modify values (and save those changes with the Apply Changes / Save button), delete that row using the Delete button, or - as previously Cancel current operation.
If you look at Form page's buttons' properties, you'll see that they have Server-side Conditions set which are then used to render (or not) a certain button. For example, if the Form page number is 13 and the primary key column is set to the ID column, then these conditions look like this:
Create: P13_ID IS NULL (i.e. the primary key column value doesn't exist yet, which means that this is a brand new row)
Apply Chanages / Save: P13_ID IS NOT NULL (i.e. the primary key column value exists, which means that row you see was fetched from the database)
Delete: P13_ID IS NOT NULL (the same condition as for the Apply Chanages / Save button)
Cancel: it is always displayed.

How to send page item values to another page without appending in url Apex 5.1.3

I am trying to redirect to another page on button click and I am setting an item value of 2nd page with value from first page.
But I can see that it is sent as a query string http://localhost:8080/apex/f?p=104:3:16676730353670::NO:RP:P3_NEW:hi
Is there any way I can send this as hidden without appending to query?
Thanks in advance
One option is to pull instead of push.
Value of P5_FINALTABLE should be in session state (for example, submit it when Enter pressed), otherwise it won't work.
Then, set P3_NEW item's "Default value" to "PL/SQL Function body" as
return :P5_FINALTABLE;
Run Page 5, enter something (for example, 555) into P5_FINALTABLE, press Enter, navigate to Page 3 and - 555 should be visible in P3_NEW item.

"general" variable in oracle apex

I'm developing an application in Oracle Application Express (APEX).
First page contains list of projects as a tabular report.
Clicking any of the rows forwards to the next page, where records can be edited. I've implemented it with following settings:
Link column: link to custom target
Target: Page in this application
Until this is fine.
My problem is how to pass actual report to the next page?
My table, which is the basis of the report has primary key (ID), and also owner & title combination is unique. Currently ID column is not included in the report.
Also the second page doesn't currently contain field showing ID, as this information isn't important to the users.
I know I could set ID column in report, and create a read only (even hidden) text box in the next page, however I'm looking for a more elegant solution. What is the standard way to solve this?
I wonder if you are asking: "How do I pass a value from page 1 to page 2 so page 2 can use the value to do a query and present the results. If so, here is how it's done.
On page P1, the report, for example, select the attributes for the report region under the region in the Rendering pane on the left of the page designed.
Under Attribute Properties on the right side, look for Link Column and set it to "Link to custom target". Then click Target.
Select the page and then in the Set Items section, on the left, under name, select the PK ID field to receive the passed value ex: P2_ID. On the right under Value select the field to pass the value, ex: #P1_ID# and click ok.
Now, when the link on page 1 report is clicked, the P1_ID is saved into Session state by Apex and passed to P2 which then performs a FETCH using the passed value.
You can read more about Session State here. Also, be aware there are security settings which affect what params can and can't be passed in the URL.
Clicking "Session" in the developer toolbar will enable you to see the session variables being passed.
If you mean "How do I store values in the app that can be accessed anywhere in the app - like a global variable" Then look at Application Items.
As always, please include version numbers in these posts.
When you create a target page let's say Page 3
And you create some items, let's say P3_ITEM_1,P3_ITEM_2, etc
You can assign values to each of them through the url in the original page
The complete APEX URL Syntax looks like this:
http://apex.oracle.com/pls/apex/f?p=AppId:PageId:Session:Request:Debug:ClearCache:Params:ParamValues:PrinterFriendly
Let’s take a closer look:
http:// – the protocol, can be http or https
apex.oracle.com – your domain/host/server, whatever you want to call it. Can also be localhost.
/pls – indicates that you are using Oracle HTTP Server with mod_plsql. If you are using APEX Listener or Embedded PL/SQL Gateway this part is obsolete/missing.
/apex – the entry from your dads.conf file (this a file on your application-server or EPG where the target database is configured) – in case of EPG its just one entry pointing to localhost, in case of an OAS you can have multiple entries, each pointing to an other database
/f?p= – procedure “f” is called and parameter “p” is set to the complete rest of the string. Remember: APEX uses mod_plsql. “f” is a public procedure, this is the main entrypoint for APEX. Or you could say: “f” is APEX.
AppId – the number or the Alias of the Application
:PageId – the number or the Alias of the Page
:Session – unique Session ID, can be 0 for Public Pages or empty (then APEX creates a new Session)
:Request – a Request Keyword. This is basically free text, just a string you can specify to react in a process or region condition on. e.g. you could pass the keyword “CREATE” and have a condition on the delete button of your page saying “dont’t display this button if request is CREATE”.
In other words: use the REQUEST to control the behaviour of your page.
When pressing a button, the button sets the REQUEST to the button-value (e.g. SAVE), so that you can control the processes in the page processing (Submit) phase.
:Debug – set to YES (uppercase!) switches on the Debug-Mode which renders debug-messages and timestamps in your Browser window. This helps to detect wrong behaviour of your page or performance issues and everything else. Every other value then YES turns the Debug-Mode off
:ClearCache – you can put a page id or a list of page ids here (comma-separated) to clear the cache for these pages (set session state to null, …). But there is more: RP resets the pagination of reports on the page(s), a collection name deletes the collection, APP clears all pages and application-items, SESSION does the same as APP but for all applications the session-id has been used in.
:Parameters – comma seperated list of page-item names. Good practice is to set only those page-items which are on the page you are going to. Accepts page-items as well as application-items.
:ParamValues – comma separated list of values. Each value is assigned to the corresponding Parameter provided in ParamNameList (first value assigned to first parameter, second value assigned to second parameter, and so on…).
The trick here is not having values which contain either a comma “,” or a colon “:”. Both would lead to side-effects and errors, as APEX gets confused when parsing the URL. Using a comma works, if enclosed by slashes: e.g. \123,89.
:PrinterFriendly – set to YES (uppercase!) switches the page into PrinterFriendly-Mode, uses the Printerfriendly template to render the Page. You can also hide regions or other elements in PrinterFriendly-Mode using the PRINTER_FRIENDLY variable in a condition.
In your case you'd use Params:ParamValues like this:
P3_ITEM_1,P3_ITEM_2:someValue_1,someValue_2
