Need Info about FileUpload

[Former Member]

Hi Experts,

Iam new to WD ABAP.

Iam uploading one file from my local system using FileUpload.

i need to do following things.

1: I should get Only name and type of file ( when getting from context that is binded, It's giving full path of file )..

2: I should upload this file from context to specified directory (say 'TEST' )location at server.

Could anybody please guide me in this regard..

Hi All,

I have one issue. I should get size of file that is uploaded.

Based on that size, I should do some operations.

Please suggest me to do this or share some code.

Thanks in advance

By using the method

FILE_GET_SIZE

of class

CL_GUI_FRONTEND_SERVICES

you will get file size.

This absolutely will NOT work! Abap WD please not suggest solutions unless you have have tried them yourself. The frontend services will not work from Web Dynpro because they require a connection to the SAPGUI. They use the control framework to access the frontend. We have no such capabilities when running inside a browser.

For Web Dynpro ABAP you would use the fileUpload. Once the content is available in the context attribute (of type XSTRING), just read the context attribute into a local variable of type XSTRING like normal. To get the lenght use the ABAP keyword XSTRLEN. This will return the lenght in bytes of the uploaded file content.

Ok, there isn't much to it but here is an example:

data filecontent type xstring.
data numbytes type i.
numbytes = xstrlen( filecontent ).

hi use this code

types: begin of t_header_text,

text0 type string,

text1 type string,

text2 type string,

end of t_header_text.

data: it_header_text type standard table of t_header_text.

data: wa_header_text like line of it_header_text.

data: node_file type ref to if_wd_context_node.

node_file = wd_context->get_child_node( 'FILE_UPLOAD' ).

node_file->get_attribute( exporting name = 'DATA' Importing value = value ).

node_file->get_attribute( exporting name = 'FILE_NAME' Importing value = FILE_NAME ).

node_file->set_attribute( name = 'FILE_NAME' value = FILE_NAME ).

conv = CL_ABAP_CONV_IN_CE=>CREATE( input = value ).

conv->READ( importing data = content ).

split content at cl_abap_char_utilities=>cr_lf into table rows .

read table rows into wa_rows index 1.

split wa_rows at '|' into:

wa_header_text-text0

wa_header_text-text1

wa_header_text-text2

Hi Narayana,

The file content will be uploaded and placed into the context attribute that you bind to the data property of the FileUpload UI element. Once the data in the context, you should take care of handling the data. You can then try save it in the location that you want. If you intend you may try having another input field where the user can enter the path to save the file in. You can then try save the data from the context attribute in that specified path.

Uday
