Server Validation Checkout Page - Retain Int Vals

Server Validation Checkout Page - Retain Int Vals

I do not require my shopper to login. Therefore there are 2 scenarios:

1. Logged in user when checkout page loads, filed are populated with init vals from rsUser.
If validation fails, init val reloads the value from rsUser

2. If user is not logged in, I want to set init value to the validated entry of the form when it is submitted. But the code is already set to rsUser field.

Is there a way to set the init value to "rsUser value", then if that is empty set it to the "validated entry field"?

One way you can check this is to use the simplified if then else notation that looks like this:
<conditional statement>?<if condition is true>:<if condition is false>

So you would want to set the value of the form field to equal that statement. For example (in pseudocode):
value=rsUser value existst?rsUser value:$_POST[form field name];

You might want to check if the post value is set on the form so something like this:
value=rsUser value existst?rsUser value: (isset($_POST[form field name])?$_POST[form field name]:"");

Jimmy,

Thanks for your response. Im having a little trouble understanding how to structure the shorthand if/then/else within a value=""

Currently i have either below (loads init val from the registered users profile)

value="<?php echo $row_rsUser['firstName']; ?>"

or (loads from validated entries rs on page reload)

value="<?php echo(ValidatedField("confirm_386","firstName")) ?>"

I'm attempting to combine the two into an if/then:

Based on your instructions
<conditional statement>?<if condition is true>:<if condition is false>

value="<?php if ( $row_rsUser['firstName'] != )?>?<?php echo $row_rsUser['firstName']; ?>:<?php echo(ValidatedField("confirm_386","firstName")) ?>"

Is that correct?

I cannot get it to work with my interpretation above. Could you advise on fixing my code. Thanks. D

You would want to check if the validated field value exists first:
(ValidatedField("confirm_386","firstName") != "")

If it is set then you want to use the value, if it isn't you want to use the value from the users registered profile:
<?php echo ((ValidatedField("confirm_386","firstName") != "")?ValidatedField("confirm_386","firstName"):$row_rsUser['firstName']) ?>

Jimmy,

Thanks for your help. I understand the shorthand if/then now.

value="<?php echo ((ValidatedField("confirm_386","firstname") != "")?ValidatedField("confirm_386","firstname"):$row_rsUser['firstName']) ?>"

The above worked. I had to make the firstName -> firstname in both places that pulled from validated fields. They used lowercase n.

This sets the init val to (1) the entered value if the text field had an entered value when submitted, then (2) rsUser -> firstName

This helps retain logged in user's data when they are logged in (optional login, not required).

Works great. Thanks again.

D.
