PHP categories showing only one item - php

Question

I'm trying to create a categories list, where user will be able to choose item with certain category, but as soon as I'm opening any of the categories, where "soon = '2'", there is only one item coming up. Everything else works.
The code bellow is for categories, where user can chose which caegory s/he want to see.
//navbar.php
<!-- Categories -->
<div class="dropdown-item menu_cat" type="button" id="catMenuButton"><i class="fas fa-caret-left"></i> Categories</div>
<form method="POST" class="dropdown-menu dropleft categories_menu row" id="cat_dropdown">
<button class="dropdown-item" name="candle"> Candles</button>
<button class="dropdown-item" name="cloth"> Clothes</button>
<button type="submit"class="dropdown-item" name="tech"> Tech</button>
</form>
Than here is everything else, that is suppose to exectute commands that will show products from category that user choose. The issue comes upp where 'if($row["soon"] == "2")' is.
//products.php
<?php
if(isset($_POST['candle'])){
$sql = "SELECT * FROM products WHERE category = 'candle'";
}else if(isset($_POST['cloth'])){
$sql = "SELECT * FROM products WHERE category = 'cloth'";
}else if(isset($_POST['tech'])){
$sql = "SELECT * FROM products WHERE category = 'tech'";
}else{
$sql = "SELECT * FROM products";
}
$result = $conn->query($sql);
if (!empty($result) && $result->num_rows > 0) {
while ($row = $result->fetch_assoc()){
if($row["soon"] == "2"){
?>
<div class="product_card col-xl-3 col-lg-4 col-md-5 col-sm-12 box-shadow">
<div class="card-header">
<h3 class="product_name my-0 font-weight-normal"> <?php echo $row["productName"] ?> </h3>
</div>
<div class="card-body">
<h2 class="card-title pricing-card-title"> </h2>
<img class="pic" src="productsImages\<?php echo $row["productID"]; ?>.jpeg" height="150px" width="120px"></img>
<br>
<p>
<?php echo $row["productPrice"]; ?> SEK
</p>
<a class="toProduct" href="products_index.php?id=<?php echo $row['productID'] ?>">
<div class="row">
<button class="btn_to_product btn btn-lg btn-outline-dark col-lg-10 col-md-10"> Go to product <i type="button" class="fas fa-arrow-alt-circle-right"></i></button>
</div>
</a>
</div>
</div>
<?php }else if($row['soon'] == "1" && isset($_POST['tech']) || isset($_POST['candle'])){?>
<div class="product_card col-xl-3 col-lg-4 col-md-5 col-sm-12 box-shadow">
<div class="card-header">

<?php
}
}
}
else if(empty($result) || $result->num_rows == 0){
echo "<h2 class='col-12'> Sorry! </h2>";
echo "<h3 class='col-12'> There is not any product in this category yet! </h3>";
}
$conn->close();
?>

Answer 1

In the original post was duplicate $row = $result->fetch_assoc(); statement.
In updated post there is first condition out of the while loop.
Solution bellow is wrapping all the if($row['soon'] into the while loop:
<div class="card-deck col-lg-12 col-md-12 col-sm-12 justify-content-center text-center">
<?php
if(isset($_POST['candle'])){
$sql = "SELECT * FROM products WHERE category = 'candle'";
}else if(isset($_POST['cloth'])){
$sql = "SELECT * FROM products WHERE category = 'cloth'";
}else if(isset($_POST['tech'])){
$sql = "SELECT * FROM products WHERE category = 'tech'";
}else{
$sql = "SELECT * FROM products";
}
$result = $conn->query($sql);
if (!empty($result) && $result->num_rows > 0) {
while ($row = $result->fetch_assoc()){
if($row['soon'] == "1" && isset($_POST['tech']) || isset($_POST['candle'])){
echo "<h2 class='col-12'> Sorry! </h2>";
echo "<h3 class='col-12'> This product will be soon avaiable </h3>";
}
if($row["soon"] == "2"){
?>
<div class="product_card col-xl-3 col-lg-4 col-md-5 col-sm-12 box-shadow">
<div class="card-header">
<h3 class="product_name my-0 font-weight-normal"> <?php echo $row["productName"] ?> </h3>
</div>
<div class="card-body">
<h2 class="card-title pricing-card-title"> </h2>
<img class="pic" src="productsImages\<?php echo $row["productID"]; ?>.jpeg" height="150px" width="120px"></img>
<br>
<p>
<?php echo $row["productPrice"]; ?> SEK
</p>
<a class="toProduct" href="products_index.php?id=<?php echo $row['productID'] ?>">
<div class="row">
<button class="btn_to_product btn btn-lg btn-outline-dark col-lg-10 col-md-10"> Go to product <i type="button" class="fas fa-arrow-alt-circle-right"></i></button>
</div>
</a>
</div>
</div>
<?php
}
}
}else if($result->num_rows == 0){
echo "<h2 class='col-12'> Sorry! </h2>";
echo "<h3 class='col-12'> There is not any product in this category yet! </h3>";
}
$conn->close();
?>
</div>
}
}else if($result->num_rows == 0){
echo "<h2 class='col-12'> Sorry! </h2>";
echo "<h3 class='col-12'> There is not any product in this category yet! </h3>";
}
$conn->close();
?>
</div>
