Pass if statement outcome to blade-CodePudding

Trying to access from Controller values to my blade

public function show(Template $template){

    if (Save::where('user_id', '=', auth()->user()->id)->count() > 0) {
        if (Save::where('title', '=', $template->title)->count() > 0) {
            //OUTPUT -  EXISTS
         } 
            //OUTPUT -  NOT EXISTS
     } 


    return view('actions/show', [
        'template' => $template
    ]);
}

How am I able to call these if statement value in show.blade.php, so I be able to make from this:

<form action="/save/{{$template->unique_key}}" method="POST">
    @csrf
    @method('PUT')
    <button><i ></i></button>
</form>

To this

if($save == 'notExists')
    <form action="/save/{{$template->unique_key}}" method="POST">
        @csrf
        @method('PUT')
        <button><i ></i></button>
    </form>
@else
    ALREADY SAVED
@endif

In your controller file. You have to have an if-else statement as well as assign a variable.

In your controller, change your code to this.

public function show(Template $template){

    if (Save::where('user_id', '=', auth()->user()->id)->count() > 0) {
        if (Save::where('title', '=', $template->title)->count() > 0) {
            $exists = true;
         } 
         else {
            $exists = false;
     } 


    return view('actions/show', [
        'template' => $template, 'exists' => $exists
    ]);
}

Now in your view file you can access it this way

if(!$exists)
    <form action="/save/{{$template->unique_key}}" method="POST">
        @csrf
        @method('PUT')
        <button><i ></i></button>
    </form>
@else
    ALREADY SAVED
@endif

This can be shortened:

public function show(Template $template)
{
    $save = Save::where('user_id', auth()->id())->exists() 
        && Save::where('title', $template->title)->exists();

    return view('actions/show', compact('template', 'save'));
}

show.blade.php

@if(!$save)
    <form action="/save/{{$template->unique_key}}" method="POST">
        @csrf
        @method('PUT')
        <button><i ></i></button>
    </form>
@else
    ALREADY SAVED
@endif

Modify your code as below. you are using same query multiple time.

public function show(Template $template){
 $save= false;
if (Save::where(['user_id'=> auth()->user()->id,'title', => $template->title])->count() > 0) {
  $save= true;
 } 


return view('actions/show', [
    'template' => $template,"save"=>$save
]);
}

In blade it will be like this.

if(!empty($save)){//exit }else{ //not exist}
