Custom Validation on Password Field

Hi @sevenlenovo

Please refer to the documentation in the link below.
https://docs.wpuserregistration.com/docs/custom-code-snippets/#18-toc-title
Does this help?

Oh I didn’t notice that page. Perfect, that worked. Thank you. I have another question I’m not sure if I should start a new topic.

Is there a way to ensure that the text area field begins with a specific word? For example if I wanted to make sure the the first word entered into the text-area is ‘apple’ (or that it contains that word at all)

Hi @sevenlenovo

Please use the following code.

add_action('user_registration_validate_textarea', 'ur_validate_user_textarea_field', 10, 4);
function ur_validate_user_textarea_field($single_form_field, $data, $filter_hook, $form_id) {
    $field_label = isset($data->label) ? $data->label : '';
    $textarea = isset($data->value) ? $data->value : '';
    
    // Split the username into words
    $textarea_words = explode(' ', $textarea);
    
    // Check if the first word is 'apple'
 if( 'textarea_1695289463' === $single_form_field->general_setting->field_name ) {
    if (isset($textarea_words[0]) && strtolower($textarea_words[0]) !== 'apple') {
        add_filter(
            $filter_hook,
            function ($msg) use ($field_label) {
                return __('The first word of ' . $field_label . ' must be "apple".', 'user-registration');
            }
        );
    }
    }
}

Make sure you replace textarea_1695289463 with the field name of your textarea field.
Please refer to the documentation in the link below for more details.

This will help you to solve the issue. Please let us know if you have any other questions.

Great, thanks that worked. Somehow though it has made the field mandatory (even though it’s not mandatory in the form builder settings.) Tried setting it to mandatory and back to optional, no luck. When field is set to optional, no asterisk is shown on the registration form but it will still give an error message that the input is invalid.

Hi @sevenlenovo

Please try the following code.

add_action('user_registration_validate_textarea', 'ur_validate_user_textarea_field', 10, 4);

function ur_validate_user_textarea_field($single_form_field, $data, $filter_hook, $form_id) {
    $field_label = isset($data->label) ? $data->label : '';
    $textarea = isset($data->value) ? $data->value : '';

    // Check if the field is not empty
    if (!empty($textarea)) {
        // Split the textarea content into words
        $textarea_words = explode(' ', $textarea);

        // Check if the first word is 'apple'
        if ('textarea_1695289463' === $single_form_field->general_setting->field_name) {
            if (isset($textarea_words[0]) && strtolower($textarea_words[0]) !== 'apple') {
                add_filter(
                    $filter_hook,
                    function ($msg) use ($field_label) {
                        return __('The first word of ' . $field_label . ' must be "apple".', 'user-registration');
                    }
                );
            }
        }
    }
}

I hope this helps.
