Step 2: Create a New Snippet

1. After activating the plugin, go to Snippets > Add New in your dashboard.
2. Choose code type as PHP snippet
3. Give your snippet a title like “Elementor Form Text Field Validation”.
4. In the code area, paste the following code:

<?php
function validate_text_field($field, $record, $ajax_handler)
{
    if (!empty($field['value']) && !ctype_alpha(str_replace(' ', '', $field['value']))) {
        $ajax_handler->add_error($field['id'], 'Please check and enter a valid response');
    }
}
add_action('elementor_pro/forms/validation/text', 'validate_text_field', 10, 3);

Explanation of the Code

The code snippet above does the following:

• validate_text_field: This function checks if the text field has any non-alphabetical characters. It uses the ctype_alpha() function, which allows only alphabetic characters (A-Z).
• str_replace(): This function removes any spaces in the input to allow names with spaces.
• If the validation fails, it shows an error message: “Please check and enter a valid response.”
• add_action(): This connects the function to Elementor’s validation process.

Note: This code only applies to text fields in Elementor forms. If you require other filed validations comment below we will send you the related code.

Step 3: Test the Validation

1. Go to the page where you’ve added the Elementor form with the text field.
2. Try entering numbers, special characters, or an invalid response in the text field.
3. Submit the form. If the entry doesn’t meet the validation criteria, the error message “Please check and enter a valid response” should appear.

Table: Validation Options with Code Snippet Explanation

Function	Purpose
validate_text_field	Checks if the input contains only letters.
str_replace(' ', '', $field['value'])	Removes spaces to allow names with multiple words.

FAQ Section

1. Can I use this code to validate other fields in Elementor?

• Yes, you can modify this code to validate other field types by changing the action hook. For example, use 'elementor_pro/forms/validation/email' for email validation.

2. Will this code affect my website’s performance?

• No, this is a lightweight snippet and should not impact performance, especially since Code Snippets is designed to handle custom code efficiently.

3. How can I customize the error message?

• You can change the text in $ajax_handler->add_error() to display a different error message.

4. What if I want to allow special characters in names, like hyphens or apostrophes?

• You can modify the validation function to allow certain special characters by using preg_match() instead of ctype_alpha().
