Handle the error when an incorrect value is inputted by user
Requirement
Handle errors that occur when user enters an incorrect value.
Use case
A company uses Zoho Recruit to maintain interview and candidate details. To let their candidates know their status, the company uses a Zoho Creator form. The candidates can enter their IDs and view their statuses. Also, the error that occurs when a candidate enters an incorrect ID is handled and a custom message is displayed.
Steps to follow
In this tutorial, the Candidate Status Without Error Handling form was created only for demonstration purpose. You may refrain from creating this form and skip steps 10 and 11 if needed.
1. Create a form with the following details.
Form | Form Link Name | Field Type | Field Name | Field Link Name |
Candidate Status | Candidate_Status
| Single Line | Candidate ID
| Candidate_ID |
Single Line | Status | Status |
Let’s now create 2 identical forms to demonstrate how the use case works with and without error handling.
2. Create two stateless forms by duplicating the Candidate Status form and name them as Candidate Status With Error Handling and Candidate Status Without Error Handling.
Note: Stateless form’s field values cannot be accessed on submit of the form since data will not be stored in Zoho Creator. Therefore in this tutorial, the status will be fetched from Zoho Creator on user input of Candidate ID field.
Let’s now remove the default buttons since they are not required for our use case.
3. Navigate to Form Properties and delete the Submit and Reset buttons from both the stateless forms.
Disable the Status field of Candidate Status - With Error Handling form so it cannot be modified by the candidates.
4. Create a workflow with the following details.
5. In the Deluge editor, save the following script to disable the Status field.
- disable Status;
Disable the Status field of the Candidate Status - Without Error Handling form so it cannot be modified by the candidates.
6. Create a workflow with the following details.
7. In the Deluge editor, save the following script to disable the Status field.
- disable Status;
8. Create a connection with the following details. This connection will be used in step 10 and 12 to fetch candidate data from Zoho Recruit.
9. Now create another workflow with the following details to populate the Status field with values fetched from Zoho Recruit. This workflow includes error handling.
10. In the Deluge editor, save the following script to fetch data from Zoho Recruit based on the supplied record ID. The code is written within a try catch block to display a custom message if an error occurs.
- try
- {
- // Fetches record from Zoho Recruit based on the record ID
- res = invokeurl
- [
- url :"https://recruit.zoho.com/recruit/v2/Candidates/" + input.Candidate_ID
- type :GET
- connection:"recruit_oauth_connection"
- ];
- // Extracts status from the fetched record
- input.Status = res.get("data").get(0).get("Candidate_Status");
- }
- catch (e)
- {
- // Displays a custom alert if an incorrect candidate ID is supplied
- alert "The entered candidate ID seems to be incorrect. Please verify. For further queries, reach us at support@zylker.com.";
- }
Note: Steps 10 and 11 are the repetition of steps 8 and 9 but without error handling. This is included in this tutorial to demonstrate how the use case works if error handling is not implemented.
11. Create another workflow with the following details to populate the Status field with values fetched from Zoho Recruit. This workflow doesn't include error handling.
12. In the Deluge editor, save the following script to fetch data from Zoho Recruit based on the record ID supplied.
- res = invokeurl
- [
- url :"https://recruit.zoho.com/recruit/v2/Candidates/" + input.Candidate_ID
- type :GET
- connection:"recruit_oauth_connection"
- ];
- input.Status = res.get("data").get(0).get("Candidate_Status");
13. Publish the Candidate Status With Error Handling form and share the permalink with the candidates. This allows the candidates to access the form without a Zoho Creator account.
