Filter content PHP - php

Question

Trying filter content with get data:
<?php
$min_quadrature = $sanitizer->text($input->get->min_quadrature);
$max_quadrature = $sanitizer->text($input->get->max_quadrature);
$min_price = $sanitizer->text($input->get->min_price);
$max_price = $sanitizer->text($input->get->max_price);
?>
<div class="gallery-items four-columns grid-small-pad">
<?php foreach($pages->find("parent=projects") as $parent): ?>
<?php
$show = "";
if(!empty($min_quadrature) && !empty($max_quadrature) && !empty($min_price) && !empty($max_price) && $parent->quadrature >= $min_quadrature && $parent->quadrature <= $max_quadrature && $parent->price >= $min_price && $parent->price <= $max_price) {
$show = "d-block";
} else if(!empty($min_quadrature) && $parent->quadrature >= $min_quadrature) {
$show = "d-block";
} else if(!empty($max_quadrature) && $parent->quadrature <= $max_quadrature) {
$show = "d-block";
} else if(!empty($min_price) && $parent->price >= $min_price) {
$show = "d-block";
} else if(!empty($max_price) && $parent->price <= $max_price) {
$show = "d-block";
} else if(empty($max_price) && empty($min_price) && empty($min_quadrature) && empty($max_quadrature)) {
$show = "d-block";
} else {
$show = "d-none";
}
?>
<div class="gallery-item projects <?= $show; ?>" data-budget="<?= $parent->price; ?>" data-quadrature="<?= $parent->quadrature; ?>">
<div class="grid-item-holder">
<?php
$image = $parent->background;
$thumb = $image->size(300, 170);
?>
<img src="<?= $thumb->url; ?>" alt="">
<div class="port-desc-holder">
<div class="port-desc">
<div class="grid-item mt-2">
<h3 class="m-0"><?= $parent->title; ?></h3>
<p class="price d-none"><?= $parent->price; ?></p>
<p class="quadrature p-0 m-0"><?= $parent->quadrature; ?> m2</p>
</div>
</div>
</div>
</div>
</div>
<?php endforeach ?>
</div>
All my items have $min_quadrature, $max_quadrature, $min_price, $max_price
I try show blocks if input data in range, my solution working bad, some combinations with all 4 input data
