_webout appends previous results.

Attyslogin · Posted 02-27-2017 11:44 PM

Dear all..

My motive is creating a login page simply & if user click submit button by entering correct credential then my choice macro [here in code it is "index page"] should run.

i have developed this code and it is working fine except my index_page macro output gets appended to the same page. i.e. _webout not clearing out previous contents.

i tried n ways options to close _webout but couldnt succeed. Any suggestions to the same code ? any other way to do the same?

kindly give your inputs. Thanks !

And yeah i have created stored process for this code where i have excluded stored process macros %stpbegin %stpend.

Code :

%MACRO LOGIN_PAGE;
data _null_;
file _webout;
PUT '<HTML>';
PUT '<HEAD> <TITLE> TITLE GOES HERE</TITLE>';
PUT '<STYLE>';
PUT 'BODY {COLOR:#d66a00; BACKGROUND:WHITE}';
PUT '.LOGIN_WINDOW { PADDING: 10PX;WIDTH:100PX;PADDING:30PX; COLOR:BLACK; background-color:WHITE; border: 3px solid LIGHTGREY;MARGIN:5em auto 0}';
PUT 'button { background-color: #a65200;color: white; border:none; cursor: pointer;width: 100PX;}';
PUT '</STYLE></HEAD>';
PUT'<BODY>';
PUT '<H1><CENTER> PAGE HEADING GOES HERE </H1> <BR>';
PUT '<form action='"&_URL"' method="POST">';
PUT '<INPUT TYPE="HIDDEN" NAME='"_PROGRAM"' VALUE='"&_PROGRAM"'>';
PUT '<div class="LOGIN_WINDOW">';
PUT '<label><b>Username</b></label><BR><input type="text" name="uname" required><BR><BR>';
PUT '<label><b>Password</b></label><BR><input type="password" name="psw" required><BR><BR>';
PUT '<button type="submit"><B>Login<B></button>';
PUT '</div>';
PUT '</FORM>';
PUT'</BODY>';
PUT'</HTML>';
RUN;

%MEND LOGIN_PAGE;

%MACRO INDEX_PAGE;
DATA _NULL_;
FILE _webout;
PUT '<HTML>';
PUT '<HEAD> <TITLE> INDEX PAGE </TITLE>';
PUT '<STYLE>';
PUT 'BODY {COLOR:#d66a00; BACKGROUND:WHITE}';
PUT '</STYLE>';
PUT'<BODY>';
PUT '<H1> <CENTER> WELCOME <CENTER> </H1> <BR>';
PUT'</BODY>';
PUT'</HTML>';
RUN;
%MEND INDEX_PAGE;

/*---------------EXECUTION SEQUENCE----------------*/

%MACRO MAIN;

%LOGIN_PAGE;

%IF "&UNAME"="HI" %THEN %INDEX_PAGE;
%MEND MAIN;
%MAIN;

Hi.

You just need to make sure that your "login_page" macro doesn't run if a username is submitted.

It could be something like

/*---------------EXECUTION SEQUENCE----------------*/
%MACRO MAIN;
%IF "&UNAME"="HI" %THEN %INDEX_PAGE;
%ELSE %LOGIN_PAGE;
%MEND MAIN;
%MAIN;

Its not working for me. Now its showing twice login page as else part is executing at initial pass.

ThomasPalm · Posted 02-28-2017 03:21 AM

This is working on my end in ordinary sas:

%global uname;
%let uname=HI;

%MACRO LOGIN_PAGE;
	%put Login_page;
%MEND LOGIN_PAGE;

%MACRO INDEX_PAGE;
	%put Index_page;
%MEND INDEX_PAGE;

/*---------------EXECUTION SEQUENCE----------------*/
%MACRO MAIN;
	%IF &UNAME eq HI %THEN %INDEX_PAGE;
	%else %login_page;
%MEND MAIN;
%MAIN;

Are you sure, that you are using the changed code in your stored process?
