If you are using RSForms Pro and need to make a free text object in the form take on a value specified by a php script (pulling data from the mysqul database typically) you can ndo the following.
1. While editing your form create a free text component and use a unique string as its text value such as "#?%?#".
2. Go to Properties tab of your form and select PHP Scripts.
3. Use the following PHP code into "Scripts called on form display":
$var="Your free text here";
$formLayout=str_replace("#?#@?#",$var,$formLayout);
Note: $var can take on the result of a function call. For example: $var = get_deadline_notice();
