Design Notes
These are notes you can input that help you and other production staff understand your confirmation elements logic and purpose. This text is never used in the live form in any way, it is only for internal development.

Confirmation/Query Condition

Confirmation Condition PHP Code

This field allows you to specify a condition which must be met for the confirmation field to be processed.

Condition Wizard

If you're new to using conditions, or simply want to have RackForms generate the condition code for you, the wizard is a fast and easy way to do so. To create a confirmation condition, simply follow the wizard from top to bottom.

Start by mousing over the This Field: select item. All fields in your form will display, select the item you want to base the condition on.

Please note if we select a Checkbox field an additional select item will display, Having This Checkbox Value (optional):. This select item will display all possible values for that checkbox. Select which value you want to base the condition on. When you do, the condition process is complete.

For all other fields, the next step is to set the Must: field. This will take the value of Equal or Not Equal, and several others.

Finally, type into the This Value: box to set which value the form field we selected above will validate against.

If you want to add additional conditions, such as a name must be Equal to Steve and age less than 10, first select the Additional Condition button and start from the top of the wizard again.

Hand Coding Conditional Code

The logic takes the form of:

Variable 1 | Condition | Variable 2

For example, let's assume we have a radio item in our form with the Name/Value of opt_1. The radio item has two possible vales, 'Yes' and 'No'. If the value of opt_1 is 'Yes' we want to send an email, if no, we do not.

We would write the Confirmation Condition PHP Code as such:

#{opt_1} == 'Yes'

In other words, we use the token for our field variable like we would in other property boxes, that is, a pound sign (#) followed by the Name/Value of the field in braces. Recall that at run time this token evaluates to the value set by our forms users, which in this case will be the value of the radio button with the Name/Value of opt_1.

We then set the comparison, in this case out comparison is equal too, denoted with the double == sign. Finally, because we know our radio item is a string value that can be 'Yes' or 'No', we wrap the value we want to check for in single tick marks.

On the raw code side, RackForms wraps the token call in an isset() block, which is further wrapped in the proper PHP if() syntax:

if(isset($_SESSION['qs']["{$_SESSION['entry_key']}"]['opt_1']) && $_SESSION['qs']["{$_SESSION['entry_key']}"]['opt_1'] == 'Yes') { // condition code start

When run, if the users set value for the radio box was 'Yes', we would process this confirmation element.

Using Array Based Form Elements (Checkboxes)
PHP Treats checkbox items a little differently than other elements. The good news is the only element that needs this special attention is a checkbox field. The difference then, is that in order to use checkbox items we need to place an index indicator just after the form field name.

For example, lets say we have a checkbox field with the Name/Value: email_condition, and it has two elements: Recipient A and Recipient B

To process this field in our condition statement we append the proper index in the format of [index-number]. It's quite simple when you see it in practice:

#{email_condition[0]} == 'Recipient A'

#{email_condition[1]} == 'Recipient B'

Please note the [0] and [1]. These are the index positions of the field being checked. Compare this to a standard field token:

#{email_condition} == 'Recipient A'

A checkbox group has several items, the [0] and [1] bit tell RackForms which number item to grab.

How do we know which number to use? In our example the checkbox field has two values, and array indexs start with 0. Thus, the first field, Recipient A, is [0], and Recipient B is [1].

The rule then is our numbering simply adds 1 for every checkbox item in the group, and always starts at 0.

IAM - Access Key

The IAM access key used for this accounts access to S3.

IAM - Secret

The IAM secret used to access this account.

AWS Region

The textual representation of the AWS Region this bucket belongs to. E.g. us-west-2, us-east-1, etc.

Bucket - Dynamic

The textual name of the S3 Bucket we'll write data too.

Key (File Name) - Dynamic

Becomes the name of the object created.

File Format

Currently we only support JSON, but will eventually add Parquet to support more complex data injection workflows.

ACL

The permission level this operation attaches to the file being written. Should almost always be private.
