IsValid
Last update:
May 18, 2026
Description
Tests whether a value meets a validation or data type rule.
Returns
True, if the value conforms to the rule; False, otherwise.
Category
Function syntax
IsValid(type, value)
isValid("range", value, min, max)
isValid("regex" or "regular_expression", value, pattern)See also
cfparam , cfform , IsBoolean, IsDate, IsNumeric, IsSimpleValue; Validating data with the IsValid function and the cfparam tag in the Developing ColdFusion Applications
History
ColdFusion (2016 release) Update 3: Added datetime_object as type.
ColdFusion 11: Behavioral change
Prior to ColdFusion 11, this function allowed currency symbols at the start and commas inside the number. Starting from ColdFusion 11, this function evaluates on a more strict basis. To revert to the old behavior use the application-level setting STRICTNUMBERVALIDATION to false.
ColdFusion 8: Added the component value for to the type parameter.
ColdFusion MX 7: Added this function.
Parameters
Parameter | Description |
type | The valid format for the data; one of the following. For detailed information on validation algorithms, see Validating form data using hidden fields in the Developing ColdFusion Applications.
|
value | The value to test |
min | The minimum valid value; used only for range validation |
max | The maximum valid value; used only for range validation |
pattern | A JavaScript regular expression that the parameter must match; used only for regex or regular_expression validation. |
Usage
The IsValid function lets you assure that validation is performed on the server. You can use the cfparam tag to perform equivalent validation.
Example
The following example checks whether a user has submitted a numeric ID and a valid e-mail address and phone number. If any of the submitted values does not meet the validation test, it displays an error message.
<cfif isDefined("form.saveSubmit")>
<cfif isValid("integer", form.UserID) and isValid("email", form.emailAddr)
and isValid("telephone", form.phoneNo)>
<cfoutput>
<!--- Application code to update the database goes here --->
<h3>The email address and phone number for user #Form.UserID#
have been added</h3>
</cfoutput>
<cfelse>
<H3>You must supply a valid User ID, phone number, and email address.</H2>
</cfif>
<cfelse>
</cfif>
<cfform action="#CGI.SCRIPT_NAME#">
User ID:<cfinput type="Text" name="UserID"><br>
Phone: <cfinput type="Text" name="phoneNo"><br>
email: <cfinput type="Text" name="emailAddr"><br>
<cfinput type="submit" name="saveSubmit" value="Save Data"><br>
</cfform>In ColdFusion 11, the isValid function behaves in a different way. Setting strictnumbervalidation to false makes the isValid function to behave in a way just like in the previous versions (ColdFusion 10 or earlier). Starting from ColdFusion 11, a more strict approach will be followed for validation. However, if you need the isValid function behavior to be of ColdFusion 10, set the key/tag attribute strictnumbervalidation to false in application cfc/cfm.
Application.cfm
<cfapplication name="hello" STRICTNUMBERVALIDATION="false" >Application.cfc
<cfcomponent>
<cfscript>
{
this.STRICTNUMBERVALIDATION = false;
}
</cfscript>
</cfcomponent>Example
<cfscript>
// check if 50 is an integer
writeOutput(isValid("integer",50)) // Yes
// check if 3.14 is a numeric
writeOutput(isValid("numeric",3.14)) // Yes
// check if it is a valid url
writeOutput(isValid("URL","http://www.example.com")) // Yes
</cfscript>Real-world uses of the isValid function
User registration and form validation
E-commerce platforms, SaaS applications, and membership sites process thousands of user registrations daily, requiring comprehensive validation of personal information, contact details, and account credentials. Invalid user data leads to failed communications, poor user experience, and database corruption. Manual validation is impractical at scale. Poor data quality costs businesses an average of $15M annually in operational inefficiencies. Use IsValid to validate email addresses, phone numbers, passwords, and personal information in real-time during user registration and profile updates.

</cfoutput>API parameter validation and security
Modern applications expose APIs for mobile apps, third-party integrations, and microservices, requiring robust parameter validation to prevent security vulnerabilities and ensure reliable data processing. Invalid API parameters cause system errors, security breaches, and data corruption. Manual parameter checking is error-prone and inconsistent. API security vulnerabilities cost organizations a lot of money per breach. Use IsValid to validate API request parameters, ensuring data types, formats, and business rules are enforced before processing requests.

</cfoutput>Financial data processing and compliance
Financial services, e-commerce platforms, and accounting systems process monetary transactions requiring strict validation of amounts, account numbers, and regulatory compliance data. Invalid financial data causes payment failures, regulatory violations, and accounting discrepancies. Financial errors can result in millions in losses and regulatory fines. Manual validation is inadequate for high-volume transactions. Use IsValid to validate monetary amounts, account numbers, tax IDs, and financial instrument data ensuring accuracy and compliance.
