How To Conditionally Enforce REGEX Validation Depending on A Custom Field Value

[Ricky Wang Lin]

Hi there.  Using either ScriptRunner / JSU / JMWE, is there a way to satisfy the following conditions:

Fields:

• *File Source - Single Select field.
  • Google
  • Yahoo
  • Bing
• *File Source URL - Single text field

Conditions:

• File Source URL will will need to begin to match the beginning depending what File Source value is selected (e.g https://google.com)
• File Source URL will need to end to match the ending in pdf

Examples:

• If File Source = Google, the File Source URL text needs to be:
  • https://google.com/file.pdf
• If File Source = Yahoo, the File Source URL text needs to be:
  • https://yahoo.com/file.pdf
• If File Source = Google, the File Source URL text needs to be:
  • https://bing.com/file.pdf

We've been able to make some progress to check use ScriptRunner's Regular expression validator [ScriptRunner] to be able to make something like this happen with the following:

^https:\/\/google.com\/.*.pdf

 However, I struggle to expand the script above to interact with another field.  Any insights is appreciated!

Hi @Ricky Wang Lin 

with JMWE, you could use a Scripted (Groovy) Validator with code like this:

switch (issue.get("File Source")) {
  case "Google": return issue.get("File Source URL") ==~ /^https:\/\/google.com\/.*.pdf/
  case "Yahoo": return issue.get("File Source URL") ==~ /^https:\/\/yahoo.com\/.*.pdf/
  default: return true //no check if another source
}

Hi David.  Thank you the response!  Is it also possible to conditionally display a different error message for each one (depending on the File Source value)?

Example:

• If someone enters "www.google.com" instead of "https:google.com",  display error message 1
• If someone enters "www.yahoo.com" instead of "https:yahoo.com",  display error message 2

Absolutely! Instead of returning a boolean value (true/false), you can return a String that will be the error message:

switch (issue.get("File Source")) {
  case "Google": return issue.get("File Source URL") ==~ /^https:\/\/google.com\/.*.pdf/ ?: "The URL is not from Google"
  case "Yahoo": return issue.get("File Source URL") ==~ /^https:\/\/yahoo.com\/.*.pdf/ ?: "The URL is not from Yahoo"
  default: return true //no check if another source
}
