IfThenElse Inside IfThenElse Formula?

[Pablo]

tanya GOOD NEWS!

The "issue" was that we didn't create the ContainsType.php to begin with <?php tag (I know, silly mistake).

Now it is working PERFECTLY! This is the final ContainsType.php

Thanks a LOT for your patience, time and knowledge.

You have saved us!

Best regards.

Should be just readable for server user. Check file owner, please

[Pablo]

Permission for ContainsType.php file is 644.

Should we change it to 777?

Thanks.

[tanya]

Check the permission of this file, please

Hi tanya

We see the following error in data/logs

[2017-04-20 14:19:43] Espo.ERROR: Formula failed: Class \Espo\Core\Formula\Functions\StringGroup\ContainsT ype was not found. [] []

Strange. We are using the same code in ContainsType and it's located in application/Espo/Core/Formula/Functions/StringGroup. You can see the ContainsType file we are using here.

What can it be?

Thanks a lot.

[tanya]

Yes, we are talking about formula

ifThenElse(string\contains(name, 'sort'), description='RESORT', description='NOSORT');

this was my test
Your example works as well (ifThenElse(string\contains(name, 'Product A'), description = 'Product A') Check data/logs

Hi tanya

This is very frustrating. We haven't been able to set it up

• Are you using the formula in the entity manager or the workflow module?
• We are trying to keep things simple for now. We are using the new formula (string\\contains(HAYSTACK, NEEDLE, OFFSET)) for cases. If we use the following formula it doesn't work:

ifThenElse(string\contains(name, 'Product A'), description = 'Product A');

• If we use the following formula it will set description as 'Product A' with ANY text used in name:

ifThenElse(string\contains(name, 'Product A') = true, description = 'Product A');

Can you please confirm your process in the tests you made? We are SO CLOSE to accomplish it!

Thanks again for your valuable time.

TRUE/FALSE result
return !(strpos($haystack, $needle) === false);
for me it works. I tested

Hi tanya ,

We used your formula but it didn't work.

Just to be clear, what is the result of the formula string\contains? Will it return the numeric position of where the NEEDLE exists relative to the beginning of the HAYSTACK string? Or is it just a TRUE/FALSE result?

Thanks.

[tanya]

ifThenElse(
string\contains(name, 'Product A'),
product = 'Product A'
ifThen(
string\contains(name, 'Product B'),
product = 'Product B')
);

[Pablo]

Awesome! Thanks tanya

We followed your instructions and see the formula string\\contains(HAYSTACK, NEEDLE, OFFSET)

Can you please specify what does each "section" (HAYSTACK, NEEDLE, OFFSET) represent?

How would our final formula be?

ifThenElse(
string\contains(HAYSTACK, NEEDLE, OFFSET) = 'Product A',
product = 'Product A'
ifThen(
string\contains(HAYSTACK, NEEDLE, OFFSET) = 'Product B',
product = 'Product B')
);

Thanks A LOT.

I didn't note, contains search mode is not supported for workflows.... sorry
you can add this function to formula

Create application/Espo/Core/Formula/Functions/StringGroup/ContainsType.php with code

namespace Espo\Core\Formula\Functions\StringGroup;

use \Espo\Core\Exceptions\Error;

class ContainsType extends \Espo\Core\Formula\Functions\Base
{
    public function process(\StdClass $item)
    {
        if (!property_exists($item, 'value')) {
            throw new Error();
        }

        if (!is_array($item->value)) {
            throw new Error();
        }

        if (count($item->value) < 2) {
            throw new Error();
        }

        $haystack = $this->evaluate($item->value[0]);
        $needle = $this->evaluate($item->value[1]);

        if (count($item->value) > 2) {
            $offset = $this->evaluate($item->value[2]);
            return !(strpos($haystack, $needle, $offset) === false);
        } else {
            return !(strpos($haystack, $needle) === false);
        }
    }
}

clear cache and use this function in formula and you don't need wildcard

How to use:
string\contains(HAYSTACK, NEEDLE, OFFSET)

Hi tanya

Thanks. I think we are overcomplicating things.

We have the advanced pack. How would you create a workflow where a fields CONTAINS a certain text? Using wildcards?

Thanks again.

[tanya]

Hello

string\\substring(STRING, START, LENGTH) Extracts the characters from a STRING by START position and LENGTH.

If LENGTH is omitted, the substring starting from START until the end of the STRING will be returned.

If LENGTH is negative, then that many characters will be omitted from the end of STRING.

wildcard like '*' doesn't work

string\substring(name, 1) = '*Product A*',

Don't you have advanced pack? Workflows can do what you want
or develop baforeSave hook for your entity (on the forum exist a lot of examples)

Hi,

We have been trying to use formulas for cases with the following criterias:

* If string name contains "Product A", set field product to "Product A"
* If string name contains "Product B", set field product to "Product B"
* If string name contains "Product C", set field product to "Product C"
* If string name contains "Product D", set field product to "Product D"

We have been testing A LOT of formulas but haven't been able to work it. We have the following for the first two criterias using wild cards:

ifThenElse(
string\substring(name, 1) = '*Product A*',
product = 'Product A'
ifThen(
string\substring(name, 1) = '*Product B*',
product = 'Product B')
);

Are we in the right track? What are we missing?

Thanks a lot and hope to hear from you.
