Field Validations
NileDesk's Field Validations feature serves as a robust data integrity mechanism. It acts like vigilant guards, making sure that the entered information follows predefined rules and standards.
By setting up these rules, we ensure accuracy and adherence to specific criteria. The main goal of these validations goes beyond just preventing errors; they also play a crucial role in ensuring the trustworthiness and reliability of the information.
For different field types, various types of validations are available. Below is a list of validations and the supported fields.
| Validation | Description | Field Type |
|---|---|---|
| Max. Length | The field must not exceed a certain number of characters | TextField |
| Min. Length | The field must be at least a certain number of characters | TextField |
| Equal To | The field must exactly match a static value or the value in another field |

| Not Equal To | The field must not be a certain static value or the value in another field |

| Contain | The field must contain certain characters, but might also have other characters | TextField |
| Does Not Contain | The field must not contain certain characters | TextField |
| Email Format | The field must be a valid email address | TextField |
| URL Format | The field must contain no spaces and a dot followed by at least two letters | TextField |
| Letters Only | The field must not have any numbers or symbols | TextField |
| Numbers Only | The field must not have any letters or symbols | TextField |
| Start With | The field must start with certain values | TextField |
| Ends With | The field must end with a certain value | TextField |
| RegEx. Expression |
Regular Expression (RegEx) validation involves using a sequence of characters to define a search pattern.
It's like creating a set of rules for matching and verifying the format of strings.
For instance, to validate an email address, you can use the following RegEx pattern:
^[a-zA-Z0-9._-]+[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$.
This pattern ensures that the email address adheres to a standard structure, validating its proper format and domain structure.
