PHP categories showing only one item

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">
          <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_soon" src="productsImages/comingSoon.png" height="150px" width="120px"></img>
          <style>
          </style>
          <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(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

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>
