Using Tooltipster Plugin with jQuery Validation for Laravel Forms

Learn how to integrate Tooltipster plugin and jQuery validation in your Laravel application, displaying error messages as visually appealing tooltips.

Have you ever struggled with displaying validation error messages in a user-friendly way for your Laravel application’s forms? Perhaps you’ve found yourself resorting to plain text error messages, which can make your form feel clunky and unappealing.

As your application grows, it’s essential to provide a better experience for your users. You’ll build a robust system that integrates the Tooltipster plugin with jQuery Validation, allowing you to display error messages in a visually appealing tooltip format. By the end of this tutorial, you’ll have a form that not only validates user input but also provides instant feedback and guidance through Tooltipster’s customizable tooltips.

Introduction to Tooltipster Plugin and jQuery Validation

As web developers, we’re constantly striving for a better user experience on our applications. Two essential tools that help us achieve this goal are the Tooltipster plugin and jQuery validation.

What is Tooltipster?

Tooltipster is a popular JavaScript library used for creating tooltips and popovers in your web application. It provides an easy-to-use API to display informative content, warnings, or errors next to form fields or any other HTML element on your page. With Tooltipster, you can create visually appealing and accessible tooltips that improve user interaction and navigation.

<!-- Example of basic tooltip usage -->
<span class="tooltip" title="This is a tooltip">Hover over me!</span>

<script>
  $(document).ready(function() {
    $('.tooltip').tooltipster();
  });
</script>

In this example, we’ve created a simple HTML element with a title attribute and initialized Tooltipster on it with $('.tooltip').tooltipster(). When the user hovers over it, Tooltipster displays the title text as a styled tooltip.

What is jQuery Validation?

jQuery validation is another essential tool for ensuring data integrity on your web application. It helps you validate user input in real-time by checking if the provided values match the expected format and rules. This prevents form submission errors and ensures a smoother user experience.

<!-- Example of basic form validation using jQuery -->
<form id="signupForm">
  <label for="username">Username:</label>
  <input type="text" id="username" name="username">
</form>

<script>
  $(document).ready(function() {
    $("#signupForm").validate({
      rules: {
        username: "required"
      },
      messages: {
        username: "This field is required."
      }
    });
  });
</script>

In this example, we’ve created a basic form with a single input field. We’ve called validate() on the form and used jQuery validation to check if the input is required and display an error message accordingly.

Both Tooltipster and jQuery validation are powerful tools that can significantly enhance your web application’s user experience. In the following sections, we’ll explore how to integrate these libraries into your Laravel project.

Installing Tooltipster Plugin via npm

Tooltipster and jQuery Validation are front-end JavaScript libraries, so you’ll install them with npm, the package manager Laravel uses for front-end assets. Run the following command in your terminal:

npm install jquery jquery-validation tooltipster

This will add the jquery, jquery-validation, and tooltipster packages to your project’s package.json file.

Once you’ve imported them (see below), compile your assets by running (or keep npm run dev running during development):

npm run build

Now that Tooltipster is installed, you need to load the plugins in your JavaScript bundle. Open resources/js/app.js and add the following imports:

// resources/js/app.js

import $ from 'jquery';
import 'jquery-validation';
import 'tooltipster';
import 'tooltipster/dist/css/tooltipster.bundle.min.css';

// Expose jQuery globally so inline scripts in Blade views can use it
window.$ = window.jQuery = $;

This loads jQuery, jQuery Validation, and Tooltipster (plus its stylesheet) through Vite, and exposes jQuery globally so it’s available throughout your application. Make sure your layout includes the bundle with @vite('resources/js/app.js'). Because Vite outputs ES modules, which run after the page has been parsed, any inline scripts in your Blade views that use $ should be written as <script type="module"> so they run after the bundle.

That’s all you need to do on the package installation side. In the next section, we’ll configure jQuery Validation with Laravel to get everything set up and ready for our form validation process. With Tooltipster installed and registered, we’re one step closer to creating a smooth user experience with error messages that appear as tooltips.

Configuring jQuery Validation with Laravel

jQuery Validation runs in the browser, but Laravel must still validate every request on the server. If your form needs custom server-side rules, you can register them in the boot() method of the app/Providers/AppServiceProvider.php file.

// app/Providers/AppServiceProvider.php

namespace App\Providers;

use Illuminate\Support\Facades\Validator;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    public function boot(): void
    {
        Validator::extend('no_spaces', function ($attribute, $value, $parameters, $validator) {
            return ! str_contains((string) $value, ' ');
        });
    }
}

This registers a custom no_spaces rule that you can use in any Laravel validation rule list, just like the built-in rules. Now, let’s configure jQuery Validation to work with our form.

In your resources/js/app.js file, below the imports from the previous section, add the validation setup:

// resources/js/app.js

// ...imports from the previous section

const customValidation = () => {
    $('#myForm').validate({
        rules: {
            name: {
                required: true,
            },
            email: {
                required: true,
                email: true,
            },
        },
        messages: {
            name: {
                required: 'Please enter your name',
            },
            email: {
                required: 'Please enter your email address',
                email: 'Invalid email address',
            },
        }
    });
};

$(customValidation);

In this example, we’re validating a form with the ID myForm. The rules object defines the validation rules for each field, and the messages object specifies custom error messages. The $(customValidation) call runs the setup once the DOM is ready, and the compiled bundle is included in your Blade templates with the @vite directive.

This setup provides a solid foundation for integrating Tooltipster with jQuery Validation in the next section.

Creating a Form with Validation Rules

Now that we have configured jQuery validation and installed the Tooltipster plugin, it’s time to create a form with validation rules.

Let’s assume we want to create a user registration form that validates email addresses and passwords. Create a new file called register.blade.php in your resources/views directory:

<!-- resources/views/register.blade.php -->
<x-layout>
    <h1>Register</h1>

    <form method="POST" action="{{ route('register') }}">
        @csrf

        <div class="mb-3">
            <label for="email" class="form-label">Email address:</label>
            <input type="email" class="form-control" id="email" name="email" required>
        </div>

        <div class="mb-3">
            <label for="password" class="form-label">Password:</label>
            <input type="password" class="form-control" id="password" name="password" required>
        </div>

        <button type="submit" class="btn btn-primary">Register</button>
    </form>
</x-layout>

In this example, we’ve created a simple form with two input fields: email and password. We’re using Laravel’s built-in CSRF token to prevent cross-site request forgery attacks.

Next, let’s create the validation rules for our form in the RegisterController:

// app/Http/Controllers/RegisterController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;

class RegisterController extends Controller
{
    public function register(Request $request)
    {
        // Define validation rules
        $rules = [
            'email' => 'required|email',
            'password' => 'required|min:8',
        ];

        // Validate input data
        $validator = Validator::make($request->all(), $rules);

        if ($validator->fails()) {
            return redirect()->back()->withErrors($validator)->withInput();
        }

        // If validation passes, create a new user...
    }
}

In this example, we’re defining two validation rules: email must be required and have a valid email format, while the password field must be at least 8 characters long. In our next section, we’ll use Tooltipster to display error messages for these fields.

Displaying Error Messages with Tooltipster

Now that we have our form validation set up and configured for use with jQuery Validation, let’s take it to the next level by incorporating Tooltipster plugin to display error messages in a more user-friendly way.

First, ensure you’ve installed the required packages: tooltipster, jquery-validation via npm. If not, run the following command:

npm install tooltipster jquery-validation

Next, let’s modify our form view (resources/views/form.blade.php) to display error messages using Tooltipster:

<!-- resources/views/form.blade.php -->

<form method="POST" action="{{ route('submit') }}">
    @csrf

    <label for="email">Email:</label>
    <input type="email" id="email" name="email" value="{{ old('email') }}" required
        @error('email') class="tooltip-error" title="{{ $message }}" @enderror>

    <button type="submit">Submit</button>
</form>

Here, we’re using the @error directive from Laravel to display error messages for the email field. When the field has an error, we add a tooltip-error class and put the message in the field’s title attribute, which Tooltipster uses as the tooltip content by default.

Now, let’s add some JavaScript code to our form view (resources/views/form.blade.php) to initialize Tooltipster:

<!-- resources/views/form.blade.php -->

<script type="module">
    $(document).ready(function() {
        const $errorFields = $('.tooltip-error');

        $errorFields.tooltipster({
            trigger: 'custom',
            interactive: true,
            side: 'top'
        });

        $errorFields.tooltipster('open');
    });
</script>

With these modifications, our form should now display error messages using Tooltipster plugin. This is a more elegant way to present validation errors to users, making it easier for them to correct their mistakes.

This handles errors returned by Laravel’s server-side validation. In the next sections, we’ll customize Tooltipster’s look and then connect it to jQuery Validation so client-side errors appear in tooltips too, before finishing with some debugging tips.

Customizing Tooltipster Styles and Settings

Now that you have Tooltipster integrated with jQuery Validation, let’s take a closer look at customizing its styles and settings.

First, you can customize the appearance of your tooltips by modifying the CSS classes applied to them. In this example, we’ll create a custom theme called tooltipster-custom by targeting the .tooltipster-box element inside it, and change its background color to a deeper blue:

.tooltipster-sidetip.tooltipster-custom .tooltipster-box {
    background-color: #2c3e50;
}

To apply these styles, create a new file in your project’s public/css directory (for example, tooltip.css), add the above code, and include it in your layout with <link rel="stylesheet" href="{{ asset('css/tooltip.css') }}">.

Next, let’s customize the settings for our tooltips. You can do this by passing an options object to the .tooltipster() method when you initialize it:

jQuery(document).ready(function () {
    jQuery('input[type="text"]').tooltipster({
        theme: 'tooltipster-custom',
        trigger: 'hover',
        side: 'bottom',
        animation: 'fade'
    });
});

In this example, we’re specifying that tooltips should be triggered on hover (trigger: 'hover'), positioned at the bottom of the element (side: 'bottom'), and animated with a fade effect (animation: 'fade'). The theme: 'tooltipster-custom' option applies the styles we just defined.

You can also customize other settings such as delay, maxWidth, interactive, and more. Consult the Tooltipster documentation for a complete list of available options.

With these customizations in place, your tooltips will now have a consistent look and feel across your application.

Integrating Tooltipster with Form Fields

Now that we have configured Tooltipster and jQuery Validation, it’s time to integrate them with form fields. This involves specifying which form elements should display error messages using Tooltipster.

Let’s start by modifying the resources/views/example.blade.php file. Add a @push('scripts') directive after the existing @section directives (your layout needs a matching @stack('scripts')):

{{-- resources/views/example.blade.php --}}

@push('scripts')
    <script type="module">
        $(document).ready(function() {
            // Prepare a tooltip on every field marked with data-tooltip
            $('#myForm [data-tooltip]').tooltipster({
                trigger: 'custom',
                side: 'right',
                animation: 'fade'
            });

            $('#myForm').validate({
                // rules and messages from customValidation()...

                // Show the error message in the field's tooltip instead of a label
                errorPlacement: function (error, element) {
                    const message = $(error).text();

                    if (message) {
                        $(element).tooltipster('content', message);
                        $(element).tooltipster('open');
                    }
                },
                // Hide the tooltip once the field is valid
                unhighlight: function (element, errorClass, validClass) {
                    $(element).removeClass(errorClass).addClass(validClass);
                    $(element).tooltipster('close');
                }
            });
        });
    </script>
@endpush

jQuery Validation only uses the options from the first validate() call on a form, so move the rules and messages from customValidation() in app.js into this call instead of validating #myForm in both places. Next, we need to specify which form fields should display error messages using Tooltipster. We can do this by adding a data-tooltip attribute to the relevant form fields:

{{-- resources/views/example.blade.php --}}

<form id="myForm" method="POST">
    @csrf

    <label for="name">Name:</label>
    <input type="text" id="name" name="name" data-tooltip required>

    <label for="email">Email:</label>
    <input type="email" id="email" name="email" data-tooltip required>

    <!-- Other form fields... -->
</form>

By specifying the data-tooltip attribute on each form field, we’re telling our script to set up a Tooltipster tooltip for those fields. jQuery Validation’s errorPlacement callback then puts each error message into the field’s tooltip and opens it, and the unhighlight callback closes it once the input is valid. Now, when a user submits the form with invalid input, Tooltipster will display an error message next to the relevant form field.

This concludes our step-by-step guide to using Tooltipster Plugin with jQuery Validation in Laravel. With these final steps, you should now have a fully functional form that displays error messages using Tooltipster.

Debugging Common Issues with Tooltipster and jQuery Validation

As you integrate Tooltipster with jQuery validation, you may encounter issues that hinder your development process. A common problem is when Tooltipster doesn’t display error messages on input fields. This can be due to incorrect initialization of the Tooltipster plugin or its settings.

To debug this issue, first verify that you have initialized Tooltipster properly by checking your JavaScript code:

$('#myForm [data-tooltip]').tooltipster({
    trigger: 'custom',
    animation: 'fade'
});

Ensure that you’re using the correct selector for your form fields. If the error persists, make sure the debug option is set to true (it is the default) for more detailed information on what’s happening:

$('#myForm [data-tooltip]').tooltipster({
    trigger: 'custom',
    animation: 'fade',
    debug: true
});

When running your application with debug enabled, Tooltipster logs warnings about problems such as invalid options in the browser console.

Another issue that can arise is when Tooltipster conflicts with other JavaScript libraries or plugins. In this case, make sure jQuery is loaded first and try loading Tooltipster after all other scripts and libraries have finished initializing:

<script src="path/to/jquery.min.js"></script>
<script src="path/to/jquery.validate.min.js"></script>
<script src="path/to/tooltipster.bundle.min.js"></script>

By troubleshooting these common issues and taking the time to understand how Tooltipster and jQuery validation interact, you can ensure a seamless user experience in your application. With these tools integrated correctly, you’ll be well on your way to creating robust, user-friendly interfaces.
