Webdynpro code

[Former Member]

Dear Expertise

I have created a login page  in webdynpro.

here's the screenshots as-

Main

View

after clicking new user from main window, i should go to view window and fill the details , then that data should be save in Z-table.

Can anyone help me with this?

Regards

Hello,

If I understand it correctly, you need the steps how to do that:

For the button 'New user' create a action. In this action you need to 'fire to a plug'(call the view). In this view you got the input fields that are connected to a node in the context.

After the user fill up the data in the input fields, for the button 'Submit' create a new action in which you read the context node to get the data from the view , and this data you will update your database table.

Have fun,

Hancila

Hello

Almost all steps i have done .

Problem lies when i am reading my input fields from in submit method,

Hi Varun,

               As i mentioned in my last reply to your other post.

just see an example

you have 3 fields A, B, C and you have ztable which has all these 3 fields

DATA : wa TYPE ztable.

wa-a = x.

wa-b = y.

wa-c = z.

update ztable from wa.

Hi,

Read the context nodes with the help of code wizard.And save/update the required values into your Z-Table .

Thanks

KH

[harsha_jalakam · Accepted solution]

Hi Varun,

You can use below sql statement to insert the records, as per your requirement. 

INSERT INTO TABLE_NAME VALUES LS_STRUCTURE.

where TABLE_NAME is the name of the table & LS_STRUCTURE is the structure values obtained by reading the context.

Thank You,

Harsha

Hi Varun,

               Double clieck on this error and go to that statement wd_this->wdctx_login )  put a space after login

[ramakrishnappa · Accepted solution]

Hi Varun,

This error is because, you have not given space between "wd_this->wdctx_login" & ")". Try to give space and check.

Hi

What is a neccessary set when user is valid?

Thank you

[ramakrishnappa]

Hi Varun,

I don't see is it a good idea to have to store user credentials in a z-table, which can be accessed by anyone, and can login , if you need to store passwords, are you considering the encryption?

What are you trying to achieve from this?

...................

Regarding your approach of development

...................

Why are you creating separate context nodes for each fields viz, user id, password?

•      Instead, create one node - REG_USER with attributes NAME, USER_ID, PASSWORD, C_PASSWORD etc.
• Read the static attributes of node at once and use it for further processing

               data lo_node type ref to if_wd_context_node.

               data ls_user_reg type wd_this->element_REG_USER

          lo_node->GET_STATIC_ATTRIBUTES( receiving static_attributes = ls_user_reg )

• Now create a temp work area of type z-table

               data ls_zdata type z_user_data.

               move-corresponding ls_user_reg to ls_zdata.

               modify Z_USER_DATA from ls_zdata.

Actually i have changed the design as well.

Created one node and in that created 3 attributes and finally read the values from code wizard.

Ok so if lsnode1 has the same field name as your ztable then just use move-corresponding remove

Wa-userid and all wa statement

Hi

Yes its working with no error .

Final , How can i check whether data is being updated in z-table.

Regards

[aarif_baig]

Go and check zentry table in se16 and c that data u put on the screen is there or not once u have saved the data and then u can close this thread

[Former Member]

Hi

Issues are still there .

Data is not being updated in Z-table

and whenever i enter password, it is again display in re-password  after clicking enter.

Put a breakpoint and check what is going wrong check if wa has value assigned to it

Hi varun acp rane is a name  and you should assign this value to character data type field check the field of the table in which yiu are passing this value has character data type defined

Hi,

I think you've binded re-enter password field context attribute value with password field context value attribute. That's why it is giving you such error.

what did you do with previous thread?

Hi

Yes you told me to do the code . That's for a single field.

I have  more fields. Do i have to read one by one all.

Regards

varun

[aarif_baig]

Yes you have to if you have defined them separately

[Former Member]

Hi

Ok , its done .i have read all the values separately .

but final query is How to update that values in Z-table?

Regards

varun

[former_member183072]

You got the values in a local structure/table. Maybe this local structure/table is not the same type like your z-table. You need to move all values to a structure/table type z-table, and after that update z-table from local structure/table.

Hope you understand,

does your ztable have all these 3 fields if yes then

just collect these values in one work area which should be like your ztable

wa-userid = lv_userid.

wa-paswd = lv_passwd.

wa-name - lv_name.

update ztable from wa.

commit work.

what is the problem you need to add the above code.

[Former Member]

Hi,

Declare one workarea of type <your custom table name>.

now assign the require field values into your workarea.

for ex : lw_workarea-newuser = lv_name .

            lw_workarea-passwd  = lv_passwd.

            now update your ztable with above workarea containing field values.

Hi Varun,

Are these two windows or views ?

If they are views, what you can do is create the nodes accordingly in component controller and read them in both the view.

For navigating between views you can make use of inbound and outbound plugs.

Regards,

Hi

Both are views .

I have created the nodes and attributes as you can see from the above posted screenshots.

Problem is with how to read the values and set them or save them in particular Z-table.
