Evaluating Strings | What Counts Knowledge Base

Overview

Several Logic Tags are used to evaluate strings and output results to the content.

Strings can be variable (set in the template %%set string1 = "Hello"%%), or Contact or Custom Data ($email, $customString). Literal strings are not supported in the following evaluation tags.

Tag	`%%eval length STRING%%`
Parameters	STRING: Variable, Custom Data, or Contact Data
Output	Output the number of characters in the string.
Example	`%%set strLength = "string"%% %%eval length $strLength%%`
Results	6

Tag	`%%eval lower STRING%%`
Parameters	STRING: Variable, Custom Data, or Contact Data
Output	Output the defined string in all lowercase characters.
Example	`%%set evalLow = "LOWERCASE"%% %%eval lower $evalLow%%`
Results	lowercase

Tag	`%%eval proper STRING%%`
Parameters	STRING: Variable, Custom Data, or Contact Data
Output	Output the defined string in all lowercase characters except convert the first character of the string to uppercase.
Example	`%%set evalProper = "proper CASE"%% %%eval proper $evalProper%%`
Results	Proper case

Tag	`%%eval upper STRING%%`
Parameters	STRING: Variable, Custom Data, or Contact Data
Output	Output the defined string in all uppercase characters.
Example	`%%set evalUp = "uppercase"%% %%eval upper $evalUp%%`
Results	UPPERCASE

Tag	`%%eval replace STRING_ORIGINAL STRING_OLD STRING_NEW%%`
Parameters	STRING_ORIGINAL: Variable STRING_OLD STRING_NEW: Variable, Custom Data, or Contact Data
Output	Set the original string to a new value by replacing the Old characters with the New characters anywhere they appear in the original string then output the results. If the original string is a custom data field, the new string will be output to the content, but is not saved to the custom data field.
Example	`%%set strOriginal = "Original String"%% %%set strOld = "Original"%% %%set strNew = "New"%% %%eval replace $strOriginal $strOld $strNew%%`
Results	New String
