In this article, we’ll dive into the features of Jodoo’s Text Field Validation plugin, explore its use cases, and provide a detailed example of how to use it with a focus on validating product codes.
What is the Text Field Validation Plugin?
The Text Field Validation Plugin is an easy-to-use tool designed to streamline form validation. By leveraging this plugin, you can define custom rules to validate text field inputs, ensuring more reliable forms and reducing user errors. The system also provides clear, customizable messages for both successful and failed validations, improving the overall user experience.
With this plugin, you can validate text fields for:
Pure Numbers: Ensure input contains only numeric values.
IP Address Formats: Validate inputs against standard IP address formats to ensure proper structured IP formats.
Custom Regular Expressions: Create tailored validation rules for complex or specific use cases, offering maximum flexibility.
Whether you’re enforcing strict input formats or handling complex data structures, Jodoo’s plugin makes validation both flexible and powerful.
Effect Demonstration
Before diving into how to configure and use this plugin, let’s explore the effect of the plugin through a practical example. Imagine you’re building a form to capture product information, and you need to validate a Product Code field.
With this plugin:
If the Product Code field is empty or doesn’t match the required format, the system will immediately display a clear error message:
“Product code format is incorrect. Please check and try again!”If the input meets the validation rules, the system will display a success message:
“Product code format is correct. Validation passed!”
How to Use the Text Field Validation Plugin?
Let’s walk through a practical example of using Jodoo’s text field validation plugin to validate a product code.
Step 1 Installing the plugin
Find and install the "Text Field Validation" plugin in Jodoo's Plugin Market. For more details on how to install plugins from the market, refer to Plugin Market.
Step 2 Enabling the plugin
After installing the plugin, go to the Plugin section, locate the Text Field Validation plugin, and toggle the switch on the right to activate it.
Step 3 Creating a form
Once the plugin is activated, you can start using it in your forms. To demonstrate how the plugin works, we’ll use a sample form to validate a product code field.
Create a new form called "Product Information Form" with the following fields:
Field Name | Field Type |
Product Name | Single Line |
Product Category | Single Select |
Product Code | Single Line |
Product Price | Number |
Launch Date | Date & Time |
Validation Result | Single Line |
Step 4 Configuring a front-end event
We want to validate the Product Code field with the following rules:
Required Field: The product code cannot be empty.
Format Validation: The product code must meet the following format:
Starts with "PROD-".
Followed by exactly 5 digits (e.g.,
PROD-12345).
Validation Messages: Display appropriate messages when the validation passes or fails.
To achieve this, we need to configure the frontend event for the form to enable real-time validation of the Product Code field.
Go to the Form Properties page, find the Front-End Event section, and click on the "Settings" button to add a new front-end event.
Provide a name and description for the new front-end event to make it easier to identify later. For example:
Event Name: Product Code Validation
Event Description: Validates the format of the Product Code field.
In the trigger action settings, select the Product Code field as the trigger field. This means that whenever a user enters or modifies the value in the Product Code field, the validation event will be triggered.
4. In the execution action settings, select the Text Field Validation plugin. And configure the validation rules as follows:
Validation Type: Select Custom Rule (Regular Expression).
Text to be Validated: Set this to the value of the Product Code field.
Corresponding Regular Expression: Use the following regex to validate the product code format:
^PROD-\d{5}$
Success Message: Set the success message to "Product code format is correct. Validation passed!".
Failure Message: Set the failure message to "Product code format is incorrect. Please check and try again!".
Explanation:
^: Ensures the string starts with the specified pattern.PROD-: Requires the product code to start with "PROD-".\d{5}: Matches exactly 5 digits.$: Ensures the string ends after the 5 digits.
5. Once all configurations are complete, click the "Save" button.
