Creating Validation Rules for Custom Fields

Custom Fields can have specific validation applied. This is to ensure Paid Registration users enter a desired value into the fields during the activation of their registration. 

As examples; 

• Limit a Custom Fields called "Member Number" to 11 numeric characters only. 

• Ask the person for a link to their Linked In profile and validate it to ensure its a valid URL. 

• Ensure a valid email address is entered into the "Alternate Email" field. 

Adding Validation

Validation is added to the following field under Event Configuration > Settings > Custom Fields.

A blank field means there are no validation rules being applied.

Validation Rules

Validation rules can be applied singular or combined into the Validation Rules field. If combined, they must be separated by pipe. e.g:

between:1,11|numeric

To use validation rules, simply paste the validation rule (e.g: "alpha" or "alpha_dash" into the Validation Rules field in the Custom Field.
