I can't work out whether its best to keep network requests down and use Alpine on the client; or to embrace the component class!

I have a form - very similar to the Tailwind widget at the start of this video, mine has the 'edit' link against each form field. Instead of showing a modal when someone clicks to edit a field, I just swap the relevant div to show the Input field.

Without going into the detail of my implentation - I just wish I'd seen this series a couple of days ago as the Entangle thing with defer looks really useful.

I'd written mine to use Alpine to only hide the input field, where the showField property was false and also the $errors for the particular field was empty too.

Looks like I could handle the error validation in the actual component class as part of a save method. The defer switch could be used to dial down unnecessary network requests too.

thanks chaudigv. I tried, but it seems the @component directive isn't playing too nice with Livewire. I started getting an error

"Undefined variable $attributes "

So, I added an attributes key and value to the array passed in.

                @component('components.descriptionlist.item',
 [  'attributes' => '' ,
     'label' => 'Full Name',
     'trackerrors' => ['person.firstname','person.lastname']
     ])

But then started getting :

Call to a member function exceptProps() on string

But, I may have just cracked it..

Back on my original version I thought I'd try out serialization / unserialization (not sure whether this is better than JSON encoding for this use case )

i.e

          <x-descriptionlist.item label="Full Name" :trackerrors=" serialize( ['person.firstname','person.lastname'] )  " >

I updated my props in the component

<div    x-data="{ editing:false,
                 passedSpecificErrors: ' {{  $errors->hasAny(unserialize($trackerrors)) }}',
                  specificErrors: '{{  $errors->hasAny(unserialize($trackerrors)) }}'
                  }"
        class="py-4 sm:py-5 sm:grid grid-cols-6 sm:gap-2 sm:px-6"
>

and it only works !! :)

For what ever reason, the HTMLSpecialChars doesn't interfere.

I'm going to try this with JSON Encode and Decode again - I thought I tried this earlier and got similar warnings from Laravel..

Thanks

You would not believe how much time I have spent trying to make this work :) More time than I am willing to admit!

I'm using the specificErrors property below, to squark, if there are any errors in the errorbag once I call save on the Person model.

You can see I have hardcoded in the person.firstname and person.lastname values.

This works perfectly, if someone causes an error on one or both of those fields ; i.e leaves it as a NULL; then the property specificErrors answers 1.

Why do I need this? Simply, because my form uses inline edits. Its a basic flag I can use to know whether I can hide the form Inputs (just basic Alpine JS is used to flick between showing the basic value; or an input field); once the user has hit save.

<div    x-data="{ editing:false,
                  specificErrors: '{{ $errors->hasAny(['person.firstname','person.lastname'])}}' }"
class="py-4 sm:py-5 sm:grid grid-cols-6 sm:gap-2 sm:px-6"
>

So the above works. It would be great to put the above into a re-usable component as there are several other fields on the Person model.

if I add a props section to the component, with the trackerrors property like this to receive errors to detect

@props(['label' => '',
        'editable' => false,
        'trackerrors'  =>'',
])

and start off the main x-data section like this

<div    x-data="{ editing:false,
                  passedSpecificErrors: '{{  $trackerrors }}',
                  specificErrors: '{{  $errors->hasAny($trackerrors) }} '
                  }"
        class="py-4 sm:py-5 sm:grid grid-cols-6 sm:gap-2 sm:px-6"
>

and in the main Blade view pass some data over like this

                       <x-descriptionlist.item label="Full Name" :trackerrors="['person.firstname','person.lastname']" >

I'm getting errors like

htmlspecialchars(): Argument #1 ($string) must be of type string, array given (View:

Can I not pass a simple array over like this? I have tried several variations, but I'm clearly missing something. Do I need to JSON encode first or something, to stop HTML Entities meddling (I know its trying to protect me)

Do you need something like

        Livewire::test(CommentsSection::class, ['post' => $post])
//            ->set('post', $post)   if you try to use ->Set, Livewire will inisit on a validation rule. 

Managed to get it working like this

    <div x-data="{ bcolor: 'red', tcolor: 'white' }">

        <div
            :style="`background-color: ${bcolor}; color: ${tcolor}`  "
        >
        Test
        </div>

    </div>

Hi

Just wanted to check I am not missing something here. In Vue JS, it is possible to data bind styles inline

<div v-bind:style="{ color: activeColor, fontSize: fontSize + 'px' }"></div>

Data block:

data: {
  styleObject: {
    color: 'red',
    fontSize: '13px'
  }
}

Alpine JS doesn't seem to support this. The x-bind works for class binding, but as soon as I try it to do a style inline in blows up!

Back to Vue JS for me I guess.

Managed to sort this in the end, the following works .

<div
    x-data="{
    bodys: {{  $component }} }
 ">

Thanks for your help. I will change the variable name from component as that is just plain confusing given the Javascript frameworks pinched that name first ! :)

thanks. I gave that a go but got

alpine.js:115 Uncaught SyntaxError: Unexpected token ';'

I wonder if something in the data has upset it...

What is the best way to get data from my database, to Alpine.JS

Say I have the following in my controller

   $component =  DB::table('config_pathway')
            ->select( 'height','width','x','y')
            ->get();

  return view('chart', compact('component'));

In my blade template I don't seem to be able to echo the view variable directly into the x-data object

<div  x-data="$component"> </div>

I have tried several variation of the above. Each attempt results in the error

Uncaught ReferenceError: $component is not defined

Yet I can access $component elsewhere in my template

Thanks

I will take a look at Livewire and see what it can do :)

I've got some flowchart UI stuff going on I've used Vue JS to handle the charting and also dynamically changing colours of boxes etc depending on the state of data.

Thanks

Hi

Can we still use Vue JS and blade templates in Laravel 8, yet still benefit from the Auth Scaffolding?

I might be wrong, from what I am reading; if we want Auth scaffolding, we have to use Jetstream which forces us to chose Blade + Livewire, or Inertia.js + Vue ?

Thanks Al
