Create user-login validation

Create user-login validation

I have a login page, requiring a username and password.

Currently if either or both are entered incorrectly, the PWEmail page is displayed inviting the user to request a forgotten password.

Is there any functionality across any of the current WA applications that will validate the user and password entry against the sql table entry and display the error message (if not validated) in the login page?

Thanks, Paul.

You would have to create two records sets, one to lookup the entered username, and another to lookup the entered password. Then you could use a show if Recordset not empty behavior for each recordset to show the correct error message and set the error message for the password recordset to include a link to the for emailPW page.

I am having a go at this but I can't get it to work.

I have created a recordset "un"
The DB column is "un"
The text field is "username"

SELECT un
FROM users
WHERE un = colname



Colname is;
Name: colname
Type: Test
Default Value: -1
Runtime Value: $_POST['username']

I have then created a "show if recordset not empty" as follows

php:
<?php if ($totalRows_un 0) { // Show if recordset not empty ?>

   Username not recognised
<?php // Show if recordset not empty ?>



But when I submit the form with an incorrect username nothing happens.
If I change it to "show if recordset is empty" the message shows when the page loads.

You want to use the show if recordset is empty:
<?php if ($totalRows_un > 0) { // Show if recordset not empty ?>
Username not recognised
<?php } // Show if recordset not empty ?>





but you also need to check whether the form was posted:
<?php if ($_SERVER["REQUEST_METHOD"] == "POST") { ?>
<?php if ($totalRows_un > 0) { // Show if recordset not empty ?>
Username not recognised
<?php } // Show if recordset is empty ?>
<?php } ?>

Sorry Jason, still cant get it to work. The error message is not visible now, but is not showing with an incorrect entry

Two problems:

2) the failed redirect for the login is set to Log_In.php, this kills the postted information and redirects back to the login page.
"failRedirect" => "Log_In.php",


change that to be blank:
"failRedirect" => "",


2) You are using show If recordset is not empty, you should be using Show If recordset is empty. Sorry, I got that backwards in my initial reply.

Thank you very much for your persistence.

I think my main problem was the redirect as I had tried the other show if behaviour.

Thanks again!!!
