FrontendForms - A module for creating and validating forms on the frontend

[Juergen]

Hello @Andy

I have tried to change the file permission of the root directory with the $files->chmod() method, but it does not work in this case. In addition it is always a little bit risky if you are changing file permissions via API. It could be a serious security issue if something went wrong.

For this reason I have decided to warn the user, if the file could not be copied to the root.

It works on my local installation but I would be happy if you try it at your environment and give me a short feedback, before I push it to Github for a new version.

All you have to do is to replace the old createRemoveCaptchaImageFile() method inside the FrontendForms.module with this new one.

  protected function createRemoveCaptchaImageFile(bool $install): void
        {
            $moduleFile = $this->modulePath . 'Formelements/Captcha/captchaimage.php';
            $rootFile = $this->wire('config')->paths->root . 'captchaimage.php';
            $from = $install ? $moduleFile : $rootFile;
            $to = $install ? $rootFile : $moduleFile;

            if($this->wire('files')->copy($from, $to)){
                if(!is_writable($to) && $install)  {
                    // captcha file could not be copied to the root folder
                    $warning_text[] = sprintf($this->_('The captchaimage.php file could not be copied to the root directory (%s), because the root directory is not writeable.'), $this->wire('config')->paths->root);
                    $warning_text[] = sprintf($this->_('Do not worry! To fix this issue, please move the file from "/site/modules/FrontendForms/Formelements/Captcha/captchaimage.php" to "%s" by yourself.'), $to);
                    $warning_text[] = $this->_('Otherwise you will get an error if you try to use the CAPTCHA on your forms.');
                    $this->wire('session')->warning(implode('<br>', $warning_text), Notice::allowMarkup);
                }
            }
            // try to unlink the file on uninstall
            try {
                // unlink the captcha.php file
                $this->wire('files')->unlink($from);
            } catch (Exception $ex) {
                $this->wire('session')->warning($ex);
            }

        }

The method checks at first if the copying was successfull. If not, it checks if the root is writeable -> if not it outputs a warning with further instructions.

This should solve the problem.

Thanks Jürgen

Hey @Juergen, trying this out for the first time here, really cool module!

I'm wondering is there a way to change or remove the wrapper for error messages? Somewhat similar to

$form->useInputWrapper(false);

If try to add

$name->setRule('required')->setCustomMessage('Please enter your name');
$name->getErrorMessage()->prepend('<small>')->append('</small>');

I'm getting

<small>
	<p class="error">Please enter your name</p>
</small>

So basically I'm trying to ditch the <p class="error"> tag for something different. Is that currently possible or would I have to fiddle with the returned string in some way?

Thanks in advance and all the best from Regensburg!

Hello @Andi

Glad to hear that you are trying out my module.

First point: prepend() and append() are not the right methods for what you try to achive. These methods will add content before and after, but they cannot replace content. So they are for adding extra markup not for changing something.😉

If you try to manipulate a single error message you can use the setTag() method directly on the input field. But please note: This will only change the error message on the given field and not on all fields:

$name->getErrorMessage()->setTag('small');

You can add every tag you want inside the parenthesis - in this case I have added the "small" tag and it works.

I guess what you are trying is to change the tag for all error messages at once.

In this case, using a Hook inside ready.php should do the trick. I write "should", but I have tried it and I do not know why, but the Hook will not be triggered. At the moment, I have no clue why it does not work, but I show you the code for the Hook that should be used inside site/ready.php.

wire()->addHookBefore('Errormessage::render', function (HookEvent $event) {
    $error_msg = $event->object;
    $error_msg->setTag('small');
});

So the render() method of the Errormessage class should be hookable (because I have made it hookable), but nothing happens. As written above, the Hook will not be triggered. Maybe it is a namespace problem, but I have also tried it with 'FrontendForms\Errormessage::render' without success. Another approach was to add the hook to the init.php instead of  the ready.php, but same result.

I am sorry, that I cannot tell you a general working solution at the moment except the first one, which is not very elegant, but I will try to trace the problem to its source.

At the moment, you can use the first method until I can give you a working solution or you will try it by yourself to get the Hook working.

Hey @Juergen, thanks for your answer. Setting the tags manually per field works fine for now!

When playing around with some of the example code earlier I noticed that none of the hooks from the docs seemed to catch on. I thought that had something to do with my setup here somehow.. But this is already very helpful 🙂

On another topic, is there a way to add an attribute to a field that has an error? After running through validation these classes are being added to the input field

<input ... class="input input-error" ...>

If I'd like to add say a

<input ... class="input input-error" aria-invalid="true" ...>

Would that be possible or would I need to do it via hook as well?

Many thanks again!!

I have discovered the same problem, but I know, that the Hook examples had worked before. This is very strange. Maybe something has been changed to Hooks since then. I know that Ryan has done some updates a while ago.

Adding extra attributes only if field is not valid is not possible via a Hook, but I can add this feature directly inside the code. I am always open on suggestions that makes the module better.

Adding the aria-invalid attribute to fields with errors is not a big deal, but I am not an expert for accessibility. Is adding the aria-invalid attribute enough or is the aria-errormessage attribute required too?

Best regards Jürgen

Hi @Juergen, I'm basically trying to get FrontendForms to play along nicely with Pico CSS, which I've recently come to love.

This is more or less what I'm trying to achieve (from the official documentation)

<!-- validation passed -->
<input ... aria-invalid="false" aria-describedby="valid-helper" ...>
<small id="valid-helper">Looks good!</small>

<!-- validation failed -->
<input ... aria-invalid="true" aria-describedby="invalid-helper" ...>
<small id="invalid-helper">Please provide a valid value!</small>

Not sure about the actual standard here, though..

Maybe an option to add attributes to valid/invalid input fields could generally be helpful?

Beste Grüße and many thanks! And good luck with the hook issue, I'll keep playing around on my end and see if I can find anything.

[Juergen]

Ok, I understand. Pico CSS sounds interesting. I have never heard about that.

So I have added the Aria attributes to the code, but you have to replace the following file: FormElements/Form.php

The Aria attributes will not be added by default, so you have to enable it on your form too:

$form->useAriaAttributes(); 

After this changes the Aria attributes will displayed properly (only) after form submission.

Instead of the aria-described-by I have used the aria-errormessage attribute, because I guess it is the better one for usage with error messages (Take a look here).

Using an additional message if field has been filled out correctly, is not really necessary or makes not a better user experience in my opinion.

<small id="valid-helper">Looks good!</small>

So I am not sure if this is it worth to add it to the form class too, but it could be realized via a new setSuccessMessage() method which will be added to an input field. This method is not implemented yet, but could be.

You can try my code above and if it works for you I can add it to the GitHub repositiory and it will be on the next update.

Ok that seems to do it 🙂

Awesome @Juergen, thanks a bunch!!

From the top of my head, one use case I could think of would be something like "Username is available" or something along these lines... Other than that, I totally agree.

Great stuff, thanks again!

[Juergen]

Great that it works as expected.

Another idea comes to my mind. I have taken a look at the Pico CSS documentation and I find it very useful (and I think other user will find it useful too).

I guess I would add this framework to the "Framework-Select" configuration in the backend.

 

If you select PICO (in the future), then the ARIA attributes will be added by default and the error messages will be rendered with <small>. So no need to adapt it by your own or use a Hook. Everything will be rendered in a way that fits well with this framework.

Fortunately this framework is so simple, that it does not need special markup treatment beside the aria attributes, so it can be realized fast without a lot of code additions.

So the next version will include this new feature, but for now I will stop the work (its weekend 😁).

So have a nice weekend!!

Version 1.2.70 is out!

This version comes with support for the Pico CSS framework, a new method to output a success message under an inputfield and a file permission check for the root directory during the module installation.

Thanks to @Andi for informing me about this CSS framework. I have never heard about it before.

Also thanks to @Andy for reporting the issue with the file permission.

Please read the changelog.md for more detailed information.

Jürgen

[Andi]

Haha, really cool @Juergen, but wasn't it supposed to be weekend? 😄

Working nicely over here, and now configuration really is a breeze!

One little thing I've come across during testing, if I disable HTML5 validation and just submit an empty form, the success message gets printed below the error (see Screenshot 1).

Steps to reproduce:

Framework -> Pico2

Field code:

// disable html5 validation
$form->setHtml5Validation(false);

// add name field
$name = new \FrontendForms\InputText('name');
$name->setAttribute("placeholder", "Name");
$name->setRule('required')->setCustomMessage('Please enter your name');
$name->setSuccessMessage('Looking good!');
$form->add($name);

And the resulting HTML, after submitting an empty form:

<input id="contactform-name" name="contactform-name" type="text" class="input input-error" placeholder="Name" required="" aria-invalid="true" aria-errormessage="contactform-name-errormsg">
<small class="error" id="contactform-name-errormsg">Please enter your name</small>
<small class="valid">Looking good!</small>

When entering a value, everything's working as expected (see Screenshot 2).

Really glad you like Pico! Just found out about it myself a few days ago in this post by @Jonathan Lahijani and I think it 's going to make a great fit for smaller PW projects.

All the best and have a nice weekend, coding or otherwise 😉

[Juergen]

Hi @Andi

Yes its weekend... or so 😁!

I have updated the module with some code changes.

What I cannot reproduce on my site is that both, the error message and the success message will be displayed side by side. I only get the error message OR the success message but not both at the same time.

I have added a check if a value is entered inside a field. If not and no error has been occured, the the success massage and the aria attributes will not be added to the input field.

Please try it and let me know if it works on your side.

Best regards

Hi, I just updated to the latest version (2.1.73) and now I get an error when using FrontendLoginRegister.

My login page now gets error

Oh snizzle… Error: Exception: Method Link::useAriaAttributes does not exist or is not callable in this context (in wire/core/Wire.php line 563)

#0 wire/core/Wire.php (419): Wire->___callUnknown('useAriaAttribut...', Array)

was there something to turn this option off?

[Juergen]

I will check this on my site. There is a function to turn this off on per form base:

$form->useAriaAttributes(false);

But I do not know if it works in your case. If not, I can give you a zip file with a previous version for replacement.

Jürgen

[Juergen]

I have fixed the bug now and bump up the version. Please be patient, in a few minutes, you can download a new version of FrontendForms, which should work.

Jürgen

[Juergen]

FrontendForms is ready to update!!

[elvina]

Thank you!

and this version has fixed the problem I was having before you updated!

My frontendlogin using a latte template was not getting redirected on login, it got stuck with the "please be patient...", but now it works all fine. 
 

[Juergen]

Version 2.1.75 is out!

This version comes with a new CAPTCHA, a new validator and 2 new methods.

Due to a user request from @Andi, I have now added a captcha that supports a question that the user has to answer. It's a perfect contrast to all the image captchas out there and can be personalized.

For example, you can ask a personal question about the company or a person, depending on the page you are running. The user must answer this question by writing the answer himself, and not by selecting a radio input. This makes the CAPTCHA very strong against SPAM.

This requires you to add several accepted answers that can be compared with the value entered by the user.

During the development of this new CAPTCHA, I have also created a new validator and 2 new methods for CAPTCHAS.

You can read about all significant changes in the changelog.md.

As always, make sure that everything works as expected and please report any problems you discover.

Jürgen

[Andi]

Awesome@Juergen, really nice work 🙂

I've added a working demonstration of a customized security question using the new compareTexts validator to the PicoWire site profile

If you want to add a customized CAPTCHA question to your form, disable CAPTCHA in the module configuration, and then add a custom text input with the new validator set as a rule

// add security question field
$question = new \FrontendForms\InputText("question");
$question->setLabel("Security question: What color is a green apple?");
$question->setRule("required")->setCustomMessage("Please answer the security question");
$question->setRule('compareTexts', ["green", "it's green", "the color green"])->setCustomMessage("Answer is not correct!");
$question->setSuccessMessage("Answer is correct!");
$form->add($question);

This way you can completely customize your field like any other input, including error and success messages 🥰

Hello @Juergen

I continue to explore your excellent module. 

And I have a few more questions. Here is the error from the console.

In continuation to this, I would like to know how I can disable the addition of frontendforms.css and frontendforms.js on all pages of the site?

I'm only willing to add these calls myself to the page where I have the form in use.

I can see that you are working hard on this project. Thank you very much.

Hello @Andy

I am a little bit confused at the error, because there is no declaration of the callback in line 1, but I will check this out.

Please click on the tab " Markup and styling settings for the form" and at the bottom you will find the tab "Remove stylesheets and scripts". In this tab you can disable the embedding of the stylesheet and the Javascript file.

Thanks for testing and reporting!!

Best regards Jürgen

[Andy]

Thank You @Juergen

I'm too inattentive. Was looking for the answer in the documentation and didn't look at the module settings. Thanks.

Now I have another problem. After installing the new version of Frontendforms 2.1.77 a captcha error comes up when submitting a form.

That's what happens after a call

Quote

if ($form->isValid()) {

 

And I have captcha disabled.

$form->disableCaptcha();

Edited May 29 by Andy

[Juergen]

OK i see, please comment out line 2019 and 2022 if you need a quick solution. It seems there is an if-condition missing that checks if a CAPTCHA is enabled. I am not at home at the moment, so I cannot fix it directly, but I will do it in the next hour and give you an info.

There is a lot of new code inside this file and some issues will pop up, so thank you for reporting this.

 

[Juergen]

Hello @Andy

The issue is fixed now inside Form.php

Please replace this file with yours, if you do not want to wait until the next update: https://github.com/juergenweb/FrontendForms/blob/main/Formelements/Form.php

BTW, the version on GitHub is actually 2.1.78 with a lot of new additions, but I have not updated the version number, because it needs a little bit more testing. So it is really cool, if users like you discover some problems before the version number will be updated 😃

[SOLVED]

The source of the error has been found. There were two closing </body> tags in the HTML layout. This caused the JS script to be called twice.
