Meilisearch Laravel Livewire component - unchecked checkboxes disappearing when using wire:model - php

Question

I'm building a full page Livewire component that filters Meilisearch results.
When I check one of the filters the remaning checkboxes disappear, and I am struggling to understand why. I followed a tutorial to figure out how to build the bulk of the component and in the tutorial the behaviour didn't occur. I've deconstructed the component to the bare minimum and the behaviour happens as soon as I wire up the checkboxes.
Here is the component:
<?php
namespace App\Http\Livewire;
use Livewire\Component;
use App\Models\CourseDate;
use App\Models\Course;
class CourseBrowser extends Component
{
public $queryFilters = [];
public $priceRange = [
'min' => null,
'max' => null
];
public function mount()
{
$this->queryFilters = [
'venue' => [],
'type' => [],
'category' => [],
'days' => [],
'supplier' => []
];
}
public function render()
{
$search = CourseDate::search(
'',
function ($meilisearch, string $query, array $options) {
$filters = collect($this->queryFilters)
->filter(fn ($filter) => !empty($filter))
->recursive()
->map(function ($value, $key) {
return $value->map(fn ($value) => $key . ' = "' . $value . '"');
})
->flatten()
->join(' AND ');
$options['facets'] = ['venue', 'category', 'type', 'supplier', 'days'];
$options['filter'] = null;
if ($filters) {
$options['filter'] = $filters;
}
if ($this->priceRange['max']) {
$options['filter'] .= (isset($options['filter']) ? ' AND ' : '') . 'price <= ' . $this->priceRange['max'];
}
return $meilisearch->search($query, $options);
}
)->raw();
$coursedates = CourseDate::find(collect($search['hits'])->pluck('id'));
$minPrice = Course::all()->min('price');
$maxPrice = Course::all()->max('price');
$this->priceRange['min'] = $this->priceRange['min'] ?: $minPrice;
$this->priceRange['max'] = $this->priceRange['max'] ?: $maxPrice;
return view('livewire.course-browser')
->with(
[
'coursedates' => $coursedates,
'filters' => $search['facetDistribution'],
'minPrice' => $minPrice,
'maxPrice' => $maxPrice,
]
);
}
}
Here is the Blade view. I had originally posted an edited section showing just the checkboxes but I have edited this question to show the view in its entirety.

The component in itself works fine. But as you can see in the gif below, the non selected checkboxes disappear, so I cannot apply multiple filters.
I suspect the problem lies in the way I'm storing the filters in the array but I can't see the woods for the trees at the moment. The filtering itself currently works, and any attempt to change the format of the array results in it not working at all.
Thanks in advance.

Answer 1

After some perusal of the Meilisearch docs:
facetDistribution contains an object for every given facet. For each of these facets, there is another object containing all the different values and the count of matching documents. Note that zero values will not be returned: if there are no romance movies matching the query, romance is not displayed.
That suggests that the behaviour is normal 😳
On updating the search results, the facetDistribution array is updated with the filters belonging to the results that have been returned, and doesn't retain the ones with a zero value.
Before filtering:
"facetDistribution":{
"category":{
"Hair":8
},
"days":{
"1":4,
"2":4
},
"supplier":{
"Matrix":8
},
"type":{
"In Person":8
},
"venue":{
"Colchester":2,
"Ipswich":1,
"Norwich":1,
"Peterborough":1,
"Romford":3
}
},
After filtering:
"facetDistribution":{
"category":{
"Hair":2
},
"days":{
"1":1,
"2":1
},
"supplier":{
"Matrix":2
},
"type":{
"In Person":2
},
"venue":{
"Colchester":2
}
},
To be honest, I'd expected to retain the filters with a value of zero so I could re-filter and find courses that were present in Colchester OR Norwich, for example. In fact the tutorial I learned the process from appeared to show this behaviour.
I'm going to rewatch it again in case I misunderstood something!
Or perhaps the older version of Meilisearch being used in the tutorial allowed this?

Answer 2

There are certain bugs in Livewire, and this is also one of them.
Try enclosing the each checkbox in a div.
<div class="">
<input type="checkbox" wire:model="queryFilters.{{ $title }}"
id="{{ $title }}_{{ strtolower($option) }}"
value="{{ $option }}">
</div>
If the issue still presist, add wire:ignore.self to container
<div class="" wire:ignore.self>
......
</div>

Answer 3

I've dumped the contents of the array as it's being filled up on the page
Each time you check a box it adds the value into the array. Obviously In the case of the Venue group of checkboxes I can't add a second value because the unselected ones disappear. But what I'd expect is an array that looks like this for example:
$this->queryFilters = [
'venue' => ['Norwich', 'Peterborough'],
'type' => ['In Person'],
'category' => ['Hair'],
'days' => [],
'supplier' => []
];
I'd then map through the values and build the filter string for Mielesearch, which happens in the closure futher down.
"venue = "Norwich" AND venue = "Peterborough" AND type = "In Person" AND category = "Hair""
