Set Max Characters for Form Fields | Zoho Creator Help

Max characters

Set max characters for form fields

Applicable to the following fields: Single lineemail, radio, and drop down .
  1. Open the form builder.
  2. Select the required field. Navigate to the  Field Properties > Validation  section on the right.

  3. Enter a value of up to 255 in the input box beside  Max Characters .
Maximum character length validation will be implemented strictly for all your form fields if a record is added via Deluge, API, or email input. This validation ensures that all the records added via various inputs undergo a thorough check for their field characters to ensure they're on par with the predefined character limits that you set, thereby minimizing error handling. 

If you set  Max Characters with a value greater than 255, Zoho Creator will display the following prompt:

In the event that you set the   Max Characters  property with a value that is less than the characters present in existing records, Zoho Creator:

  • Allows the existing records to be updated if the data stored in that field is left unchanged
  • Applies the new value to validate the existing records if the data stored in the that field is edited
  • Applies the new value to validate records added after this change

This behavior is in place to ensure that existing records are not affected.
