Formula - Replace (v6+)

[espcrm]

https://docs.espocrm.com/user-guide/...sions/#replace

(Please note, I mistakenly used Complex Expression instead of Formula, however there is a solution for both method thanks to item and Maximus)

I'm trying to use the replace formula and having difficult with it, anyone know how to use it?

Here is my formula but not getting it to work.

filename = string\concatenate(iD, ' - ', name);
filename = replace('test0', 'test1', 'test2');

Seeing that it didn't work, I decide to just comment out the first line to see if my Replace formula work at all. Still no luck so I also tried to just have 2 string. But still nothing, anyone know how to use this formula? It a new feature from v6.

/* filename = string\concatenate(iD, ' - ', name); */
filename = replace('test0', 'test1');

I'm planning to replace all non-compatible character filename, for example these type of characters \ / : ; ? change to _

Hello,
i can try it ... but need more info :
i use this :
$name = $entity->get('xmlNumber').'-' .\Espo\Core\Utils\Util::sanitizeFileName($entity->get('name')). '.pdf';

so special char are disabled...
maybe i can make a special formula for you

just one requirement : the function name must be name : replaceByItem( field ) (joke)
Regards

$newPathToFile = preg_replace('/\s+/', '_', $pathToFile);

Hello folks,
I just want to add my 5 cents here. espcrm the link you provided (https://docs.espocrm.com/user-guide/...sions/#replace) is not about Formula. It applies to Complex expressions. So the formula: replace('test0', 'test1', 'test2'); is wrong.
The appropriate formula is located here https://docs.espocrm.com/administrat...#stringreplace. You can utilize the regEx with it. See regEx tips here https://docs.espocrm.com/administrat...a/#stringmatch.

Wow how silly of me! Thank Maximus. But look like item just created a great tutorial anyhow.

I will give stringreplace a try. And link the thread on the 'wiki' for future user for Complex Expression

Hi guys,

I just tried using this formula and having trouble with it still. Not sure how to use it. Tried variation of it (many of which isn't copy/paste) but never got the formula to work, here is some of the formula I tried.

name = string\replace('Hello {description}, '{description}, 'world)
string\replace('Hello {description}, '{description}, 'world)
string\replace('Hello {name}, '{name}, 'world)
string\replace("Hello {name}", {name}, "world")
string\replace("Hello", world, {name})

And my field value:

World 1 Hello World 1 1 World Hello {name} World {name}

Basically I just want to able to Replace all "Hello" to "World" in the {name} field. Anyone can point me in the right direction? The example code in documentations is difficult to understand as it is not a live working example.

[Maximus]

Hi,
This works like a charm:

name = string\replace('Hello {test}', '{test}', 'world');

[espcrm]

Thank Maximus, it does seem to work, it is because it is missing the ending ' symbol? Should documents be update to include those.

However the issue is that using this formula it is replace everything and delete all the other words.

For example:

Hello Hello 123 > Formula > Hello World

How would I make the formula like this?
Hello Hello 123 > Formula > World World 123

Or is it not possible with the current formula system?

And what is {test} field?

[item]

Hello,
document where updated, yes missing typo '

sample :
result = string\replace('Hello item', 'item', 'espcrm');

result => Hello espcrm

https://www.php.net/manual/fr/function.str-replace.php

[Maximus]

For Hello Hello 123 > Formula > World World 123 try this:

name = string\replace('Hello {123} 123', '{123}', 'World');

{tests} and {123} it is just like a variable for the second element. You can put any value within {} that you want.

Finally success! Thank you for your help guys. Finally got it to work based on those formula.

Some learning can be found here of my trial can be found here: https://forum.espocrm.com/forum/gene...6269#post66269

If you just want the code; this is the final code I used to replace all "Hello" with the "World" without affecting what is inputted in the field: name

name = string\replace(name, 'Hello', 'World');

Hello Testing the Formula Hello Again > (Formula) > World Testing the Formula World Again

Greats ... happy for you.. need help.. don't hesitate to post

Nothing much, but here is my formula to replace the address to a more acceptable format for Windows PC. This is use for Real Estate extensions where I replace the text "/" with "_", you can use this for Contact and Account as well or anywhere that have address field.

The reason I need this because / is usually use for Unit address in my country which doesn't play well with Windows PC. Using this formula string will replace the / with _. You may have to change your field name slightly for it to work fully for you.

ifThenElse(
addressStreet,
folderNameProp = string\concatenate(addressStreet, ", ", addressCity, " ", addressState, " ", addressPostalCode," (", propertyREID, ")"),
folderNameProp = string\concatenate(addressCity, " ", addressState, " ", addressPostalCode," (", propertyREID, ")")
);
folderNameProp = string\replace(folderNameProp, '/', '_');

folderNameProp is field name I want to concatenate the address
I use ifThenElse because sometime I don't have street name, only city name (Place of Birth)
propertyREID is my custom field which auto-increment so I can give each address a numbers for importing/exporting or identificaiton

finally I string replace the / (slash) to _ (underscore).

For example input of the address:

Input: Unit 1/2 Streetname, City STATE Postcode
Output: Unit 1_2 Streetname, City STATE Postcode
