Functions

Use functions to transform data from records, perform calculations, or to provide values for Visualforce attributes.
Functions must be used in a Visualforce expression to be evaluated. You can use the following functions in your Visualforce pages.

Within an email template, merge fields can only be used in formula functions and operations when the merge field belongs to the record the email will be related to, otherwise these fields won’t resolve.

Note

Date and Time Functions

The date/time data type might not evaluate correctly in formula expressions for Visualforce pages with an API version less than 20.0. It may be incorrectly interpreted as just a date type.

Note

Function Description Use
ADDMONTHS Returns the date that is the indicated number of months before or after a specified date. If the specified date is the last day of the month, the resulting date is the last day of the resulting month. Otherwise, the result has the same date component as the specified date. ADDMONTHS (date, num) and replace date with the start date and num with the number of months to be added.
DATE Returns a date value from year, month, and day values you enter. Salesforce displays an error on the detail page if the value of the DATE function in a formula field is an invalid date, such as February 29 in a non-leap year. DATE(year,month,day) and replace year with a four-digit year, month with a two-digit month, and day with a two-digit day.
DATEVALUE Returns a date value for a date/time or text expression. DATEVALUE(expression) and replace expression with a date/time or text value, merge field, or expression.
DATETIMEVALUE Returns a year, month, day, and GMT time value. DATETIMEVALUE(expression) and replace expression with a date/time or text value, merge field, or expression.
DAY Returns a day of the month in the form of a number between 1 and 31. DAY(date) and replace date with a date field or value such as TODAY().
HOUR Returns the local time hour value without the date in the form of a number from 1 through 24. HOUR(time) and replace time with a time value or value such as TIMENOW().
MILLISECOND Returns a milliseconds value in the form of a number from 0 through 999. MILLISECOND(time) and replace time with a time value or value such as TIMENOW().
MINUTE Returns a minute value in the form of a number from 0 through 60. MINUTE(time) and replace time with a time value or value such as TIMENOW().
MONTH Returns the month, a number between 1 (January) and 12 (December) in number format of a given date. MONTH(date) and replace date with the field or expression for the date containing the month you want returned.
NOW Returns a date/time representing the current moment.
The NOW function returns the current date and time in the GMT timezone. {!NOW()} For example:
Today's date and time is: {!NOW()}
produces the following:
Today's date and time is: Mon Jul 21 16:12:10 GMT 2008
Tips
  • Don’t remove the parentheses.
  • Keep the parentheses empty. They do not need to contain a value.
  • Use addition or subtraction operators and a number with a NOW function to return a different date and time. For example {!NOW() +5} calculates the date and time five days ahead of now.
  • If you prefer to use a date time field, use TODAY.
NOW()
SECOND Returns a seconds value in the form of a number from 0 through 60. SECOND(time) and replace time with a time value or value such as TIMENOW().
TIMENOW Returns a time value in GMT representing the current moment. Use this function instead of the NOW function if you only want to track time, without a date. TIMENOW()
TIMEVALUE Returns the local time value without the date, such as business hours. TIMEVALUE(value) and replace value with a date/time or text value, merge field, or expression.
TODAY Returns the current date as a date data type.
The TODAY function returns the current day. For example, The following markup:
Today's date is: {!TODAY()}
produces the following output:
Today's date is: Mon Jul 21 00:00:00 GMT 2008
Tips
  • Do not remove the parentheses.
  • Keep the parentheses empty. They do not need to contain a value.
  • Use addition and subtraction operators with a TODAY function and numbers to return a date. For example {!TODAY() +7} calculates the date seven days ahead of now.
  • If you prefer to use a date time field, use NOW.
TODAY()
WEEKDAY Returns the day of the week for the given date, using 1 for Sunday, 2 for Monday, through 7 for Saturday. WEEKDAY(date)
YEAR Returns the four-digit year in number format of a given date. YEAR(date) and replace date with the field or expression that contains the year you want returned.

Logical Functions

Function Description Use
AND Returns a TRUE response if all values are true; returns a FALSE response if one or more values are false.

{!IF(AND(Price < 1,
   Quantity < 1),
   "Small", null)}

You can use && instead of the word AND in your Visualforce markup. For example, AND(Price < 1, Quantity < 1) is the same as (Price < 1) && (Quantity < 1).

BLANKVALUE(expression, substitute_expression) and replace expression with the expression you want evaluated; replace substitute_expression with the value you want to replace any blank values.
CASE Checks a given expression against a series of values. If the expression is equal to a value, returns the corresponding result. If it isn't equal to any values, it returns the else_result. CASE(expression,value1, result1, value2, result2,..., else_result) and replace expression with the field or value you want compared to each specified value. Replace each value and result with the value that must be equivalent to return the result entry. Replace else_result with the value you want returned when the expression doesn't equal any values.
IF Determines if expressions are true or false. Returns a given value if true and another value if false.
The following markup returns “Private” if the opportunity IsPrivate field is set to true; it returns “Not Private” if the field is set to false.
{!IF(opportunity.IsPrivate, "Private", "Not Private")}
IF(logical_test, value_if_true, value_if_false) and replace logical_test with the expression you want evaluated; replace value_if_true with the value you want returned if the expression is true; replace value_if_false with the value you want returned if the expression is false.
ISBLANK Determines if an expression has a value and returns TRUE if it does not. If it contains a value, this function returns FALSE. ISBLANK(expression) and replace expression with the expression you want evaluated.
ISCLONE Checks if the record is a clone of another record and returns TRUE if one item is a clone. Otherwise, returns FALSE. ISCLONE()
ISNEW Checks if the formula is running during the creation of a new record and returns TRUE if it is. If an existing record is being updated, this function returns FALSE. ISNEW()
ISNULL Determines if an expression is null (blank) and returns TRUE if it is. If it contains a value, this function returns FALSE.
(IF(ISNULL(Maint_Amount__c), 0, 1) + ​
 IF(ISNULL(Services_Amount__c), 0,1) + ​
  IF(ISNULL(Discount_Percent__c), 0, 1) + ​
   IF(ISNULL(Amount), 0, 1) +​
    IF(ISNULL(Timeline__c), 0, 1)) / 5
ISNUMBER Determines if a text value is a number and returns TRUE if it is. Otherwise, it returns FALSE. ISNUMBER(text) and replace text with the merge field name for the text field.
NOT Returns FALSE for TRUE and TRUE for FALSE.
The following markup returns the value of ReportAcct if the account IsActive field is set to false. It returns the value of SaveAcct if IsActive is set to true.
{!IF(NOT(Account.IsActive)ReportAcct, SaveAcct)}

You can use ! instead of the word NOT in your Visualforce markup. For example, NOT(Account.IsActive) is the same as !Account.IsActive).

NOT(logical) and replace logical with the expression that you want evaluated.
NULLVALUE Determines if an expression is null (blank) and returns a substitute expression if it is. If the expression is not blank, returns the value of the expression. NULLVALUE(expression, substitute_expression) and replace expression with the expression you want to evaluate; replace substitute_expression with the value you want to replace any blank values.
OR Determines if expressions are true or false. Returns TRUE if any expression is true. Returns FALSE if all expressions are false.
The following markup will return the value of VerifyAcct if either account field IsActive__c or IsNew__c is set to true.
{!IF(OR(Account.IsActive__c, 
   Account.IsNew__C)) 
   VerifyAcct, CloseAcct)}

You can use || instead of the word OR in your Visualforce markup. For example, OR(Price < 1, Quantity < 1) is the same as ((Price < 1) || (Quantity < 1)).

OR(logical1, logical2...) and replace any number of logical references with the expressions you want evaluated.
PRIORVALUE Returns the previous value of a field. PRIORVALUE(field)

Text Functions

Function Description Use
BEGINS Determines if text begins with specific characters and returns TRUE if it does. Returns FALSE if it doesn't.
The following markup will return true if the opportunity StageName field begins with the string “Closed”. Standard stage names “Closed Won” and “Closed Lost” would both return true.
{!BEGINS(opportunity.StageName, 'Closed')}

This function is case-sensitive so be sure your compare_text value has the correct capitalization. Also, this function only works with text, not with numbers or other data types.

BEGINS(text, compare_text) and replace text, compare_text with the characters or fields you want to compare.

Inputs are optional and can include any additional parameters you want to add to the link. The no override argument is also optional and defaults to “false.” It applies to targets for standard Salesforce pages such as $Action.Account.New. Replace no override with “true” when you want to display a standard Salesforce page regardless of whether you have defined an override for it elsewhere.
PREDICT Returns an Einstein Discovery prediction for a record based on the specified record ID or for a list of fields and their values. PREDICT(PredDefId, [recordId] | [field, value, ...]). Replace PredDefId with the Prediction Definition ID of a deployed prediction in your org. Specify the recordId of the record to predict or a list of fields and their associated values ([field, value, ...]).
REGEX Compares a text field to a regular expression and returns TRUE if there is a match. Otherwise, it returns FALSE. A regular expression is a string used to describe a format of a string according to certain syntax rules. REGEX(text, regex_text) and replace text with the text field, and regex_text with the regular expression you want to match.
REQUIRESCRIPT Returns a script tag with source for a URL you specify. Use this function when referencing the Lightning Platform AJAX Toolkit or other JavaScript toolkits. {!REQUIRESCRIPT(url)} and replace url with the link for the script that is required.
URLFOR Returns a URL for an action, an s-control, a Visualforce page, or a file in a static resource archive. URLFOR is available for use in custom buttons and links, s-controls, and Visualforce pages.

To return a reference to a file contained in a static resource archive (such as a .zip or .jar file), use the format {!URLFOR(resource, path)}. Replace resource with the name of the static resource archive expressed as a merge variable (for example, $Resource.resourceName), and path with the local path to the file in the archive that you want to reference.

As of Winter ’25, all Visualforce pages are served on the force.com domain or a site domain. URLFOR currently returns an absolute URL for all Visualforce pages. See Ensure Access to Your Visualforce Pages in Summer ’24 and Winter ’25.

Note

{!URLFOR(target, [id], [inputs], [no override])} and replace target with the URL or action, s-control, or static resource merge variable; id with an optional reference to the record; and inputs with any optional parameters. The no override argument is also optional and defaults to false. It applies to targets for standard Salesforce pages such as $Action.Account.New. Replace no override with true when you want to display a standard Salesforce page regardless of whether you have defined an override for it elsewhere.
To access a Visualforce page, enter the page name preceded by $Page. For example, if your Visualforce page is named myTestPage, use:
{!URLFOR($Page.myTestPage)}
The input values can be dynamic. For example, to include an account ID, specify:
{!URLFOR($Page.myVisualforcePage, null, [accountId=Account.Id])}

The resulting URL would include a parameter with the ID, such as:

https://MyDomainName--PackageName.vf.force.com/apex/myVisualforcePage?accountId=001B0000002txol

Because parameter names are static, you can’t use a variable to determine the parameter name. For example, if you use [myVariable="value1"] and set myVariable to "param1", the resulting URL includes ?myVariable=value1 and not the param1 value.

Note

VLOOKUP Returns a value by looking up a related value on a custom object similar to the VLOOKUP() Excel function. VLOOKUP(field_to_return, field_on_lookup_object, lookup_value) and replace field_to_return with the field that contains the value you want returned, field_on_lookup_object with the field on the related object that contains the value you want to match, and lookup_value with the value you want to match. You can only use VLOOKUP() in validation rules. If the function fails because, for example, the field_on_lookup_object doesn’t exist, you can specify an error message in the validation rule itself.
