[SOLVED] Auto Actions - Registration (modify field before saving)

I'm using the "get_field" method to register users via auto actions as mentioned here:

I'm placing [get_email] in the email field and passing the email as a variable. The problem is I need to be able to add a "+something" before the @ sign within that email field.

For example, if the email variable being passed is john@domain.com , I need to be able to save it as john+something@domain.com . Is there a way to do this?

I don't mind creating another action after the registration is complete and changing that field. I noticed there is a "multiply, divide, add, subtract" operators under the "Field" type action.

Yes, but wouldn't it just be massively easier to simply pass john+something@domain.com to begin with. You'll have to use a combination of format functions that you'll need to enable under the Parameters tab. Specifically extract, position, etc.. to split the string apart.

Yes that would be easier, however it is being passed in tact as a variable from another CRM. And since I can't break it up on their end, I have to break it up on my end.

Any examples I can look at to do this?

You're basically using substr and strpos via the extract (substr) and position (strpos) format functions. The below might work. Below might work, but I didn't test it.

Can I get a step by step on this? I tried a few things but it's not working for me.

First you need to grab the position of @ as you would with PHP strpos to see where it's at in the string. This is done as follows.

[cb:parse function="position" search="@"][get_email][/cb:parse]

Next you need to grab the string beginning at @ and onwards so you can insert before it. This is done by passing the result of the above to

[cb:parse function="extract" start="POSITION_HERE"][get_email][/cb:parse]

That gives you "@domain.com". Now you need the beginning of the email address. This is done by grabbing the string from 0 (beginning of the string) to the @ using the length parameter as follows.

[cb:parse function="extract" start="0" length="POSITION_HERE"][get_email][/cb:parse]

That gives you "john". Now you'd combine the 2 usages to add whatever you want between them as follows.

START+testEND

The usage in my above reply does exactly this, but it's not going to do anything unless you've turned on Format Functions under the Parameters tab of your auto action as by default format functions only work for conditions.
