Utilizing RegEx (Regular Expressions) to limit who can use On Line Registration for Charter school (or other special schools that might be limited) Regular Expressions (regex) are a powerful tool used for pattern matching and searching within strings of text. They allow you to define complex search patterns that can be used to find, replace, or validate text based on certain criteria. A regex consists of characters that represent patterns, such as:
Literal characters: Match themselves (e.g., "a" matches "a"). Special characters: Represent actions or types of matches, like: - . (dot) matches any character except a newline. - \d matches any digit. - \w matches any word character (letters, digits, underscores). - * matches zero or more of the preceding element. - + matches one or more of the preceding element. - ^ indicates the start of a string. - $ indicates the end of a string.
For example:
- \d+ matches one or more digits. - ^\d{3}-\d{2}-\d{4}$ matches a U.S. Social Security number (like 123-45-6789).
By adding RegEx you can set a criteria to look for before someone can finalize On Line Registration.
I will show how to create a User Defined page and fields to request a specific code given to a parent once they have been accepted by a Charter School. If the parent does not use the correct code they will be directed to contact the Charter School for the code or fill out the non Charter Registration. You can even have a specific code for multiple schools and each code will take them to that specific Charter Registration.
