Hi Jessica,
You can perfectly say Change value ABC=NULL. This should work - I am doing it all the time

Hi Helen! But won't that null out ALL values? If I have A;B;C as values, I only want to take away A, leaving B and C...

Oh I see. No, that won't work then. How do you store the values? In the text area?

Re: How to de-select a value from a multi-select field?
Yes - in this format - A;B;C which then checks the relevant values in the Salesforce multi-select picklist. Can't for the life of me figure it out! May need to handle in Salesforce.

I would suggest considering creating custom fields for A, B, C and keep them updated dynamically. If you need to keep them in one field, then you can use tokens to concatenate and update the target field. Multi-select is not well supported by Marketo. Building all the choices seem too much pain.

Re: How to de-select a value from a multi-select field?
1 of 1 people found this helpfulThe way to do this is via webhook, which can parse semicolon-delimited (or anything-delimited) strings and return them with certain values excised.

Sanford, this is great - do you have an example of how this is done? Haven't parsed things in this way before. Thanks!!

Re: How to de-select a value from a multi-select field?
How are you triggering the data value changes flow?
i.e. how are you selecting which value inside the multi picklist to take out?
or is this data hygiene that you'd run manually?
Anyway here's a php webhook that does the trick:
<?php if(isset($_POST['data']) && isset($_POST['var'])){ $data = $_POST['data']; // e.g. "product a;product b;product c;product d;" $var = $_POST['var']; // e.g. "product c" $response = preg_replace( "/$var\;/", "", $data); // gives "product a;product b;product d;" echo json_encode(array("response"=>$response)); // In Marketo map 'response' to update multi select field } ?>-

Will both false positive and mangle output on partial match, you must split on the delimiter

Gettin' there.
<?php $purchases = "39;44;21;0;89"; assert( implode(array_filter(explode(";",$purchases)),";") == "39;44;21;0;89" ); // assertion failedNo embedded string values should be special in parsing. "0" is coerced to boolean false in PHP.

Re: How to de-select a value from a multi-select field?
I'll trust ya that it's working now.
But this is a great case of PHP showing its clunkiness and lack of fluency (in both senses of the word!).
Which is why I'd do it like this:
