Cannot populate email recipient from recordset

Cannot populate email recipient from recordset

I have a form in which I pass to it a key value for a database table lookup. The form when opened will query the table from that passed key and return a name and an email address. This all works perfectly. It is when I try to send an email to that dynamically obtained email address that everything falls apart...

I used the dynamic button to populate the TO field in the email config part of the form wizard with the recordset value for the email address. But after sending the email nothing ever gets sent. Upon enabling error reporting I found the email address is not being sent to the email system as expected. In fact that TO field remains blank.

Using the dynamic button to populate the TO field with my recordset email address should work I would expect, but it is not. What do I need to do to fix this?

FYI I am using the most current version: 2.0.1

the thing to understand with forms is that they reload the page.

you say:
"I have a form in which I pass to it a key value for a database table lookup."

I suspect this is a querystring value, right? for example:
pagename?id=4


when the form submits, it causes the page to reload.

the form uses the action attribute to tell the server what page to load, if the querystring variable is not included in the action attribute, it will cause the recordset to return an empty data set.

you can use the following code for the form action:

php:
 action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?><?php echo (isset($_SERVER["QUERY_STRING"]) && $_SERVER["QUERY_STRING"] != "")?"?".htmlspecialchars($_SERVER["QUERY_STRING"]):""?>"




this will automatically include any querystring values that are passed into the page when the form submits.

Issue solved, but...

First off, I do want to report my problem has been resolved.

While I greatly appreciate your very prompt response, I am puzzled as to why this was necessary in the first place. It seems this is a glaring defect in the code I hope will be fixed soon.

this is not necessarily a defect in the code.

not all pages will have a query string passed in.

Not all pages that do have a query string passed in will require that the query string be passed with the form submission.

in actual fact server issues can arise from automatically assuming that the query string passed in should be included in the forms action. it's better to add the code that I posted for you on an as needed basis rather than automatically use it on every form, where it will only be needed in a small number of cases.
