Zoho Forms - Regex Field for Structured Data Validation

Zoho Forms has added a Regex field that validates what respondents type against a pattern you define, rather than accepting any input like a standard text field.

• If a value does not match the pattern, the field shows a custom validation message and the respondent has to correct it before submitting.
• Validation runs in real time as the respondent types, so formatting problems are caught during completion rather than after the fact.
• You define the pattern, write the error message respondents see, and can optionally add placeholder text showing an example.
• Patterns can be split across several rows and joined with separators, for example three numeric groups divided by hyphens to enforce a fixed identifier format.
• Typical uses include employee IDs, national identification numbers, tax registration numbers, licence numbers, customer reference IDs, membership numbers, internal case numbers and asset or inventory codes.
• A set of preset regex patterns covers common cases, and Zoho has documentation explaining what each regex symbol does.
• The field appears under the Textbox section of the form builder.
