RegEx for Dynamic URL Goals settings

I have tried to work this RegEx to set up a goal in GA for 2 days, but I cannot get my head around it...

The URL format is like this:

/purchase.php?cDd=1&transaction_id=xxxxxxx&verify=xxxxxxxxxxxxxxxx=&method=creditcard&t开发者_C百科ype=purchase

transaction_id= is populated with a sept of numbers verify= is populated by a string of numbers, letters in both caps and lower case

Basically I would like to only match URLs which finish by &method=creditcard&type=purchase

I have tried to just put &method=creditcard&type=purchase but it does retrieve other URLs too.

Put a $ sign at the end of your regex.

This way you enforce to only match url's that end with &method=creditcard&type=purchase

^/purchase.php\?cDd=1&transaction_id=[0-9]*&verify=[a-zA-Z0-9]*=&method=creditcard&type=purchase$

or

&method=creditcard&type=purchase$

would do the trick

For any dynamic URL

^/(.*)&method=creditcard&type=purchase$
