How to add a new html table row each time mysql query is executed

Question

I was wondering if it is possible to query a database, and each time a submit button is clicked, it will add a new row to the table, instead of refreshing the page.

You see, what's happening is that when I run the query, it will add the row successfully, but when I run the query again, it will refresh the page, essentially only being able to add only one row at a time.

Basically, I want to be able to create a table which will add a product to the list each time I scan a barcode with a barcode scanner. As the user scans the code, the query will execute to grab the relevant data from the database, and display a row.

 $barcode = $_POST["Barcode"]; $query = "Select * from products WHERE ProductBarcode = $barcode"; $result = $mysqli->query($query); if ($result->num_rows > 0) { echo "<table> <tr> <td><strong>ID</strong></td> <td><strong>Name</strong></td> </tr>"; // output data of each row while($row = $result->fetch_assoc()) { echo "<tr><td><input type='checkbox' value='".$row['Row_ID']."' />".$row['Row_ID']."</td> <td>".$row['ProductName']." "."</td></tr>"; } echo "</table>"; } else { echo "0 results"; } $mysqli->close(); 

Answer 1

You can use jQuery/ajax to achieve this. Check out this post. I believe it has exactly what you're looking for: Creating a table with mysql, php and ajax (with jquery)

Answer 2

You can do this Using Ajax

I'm writing an Psudo code which will give you and idea how to do this

Step 1: create a table and define table Id

<table id="myTable">
<tr>
    <td><strong>ID</strong></td>
    <td><strong>Name</strong></td>
    </tr>
</table>

Step 2: Submit Your Barcode Data or product Id using Ajax

<script>
$(document).on('click', "#submitButton", function () {
var barcode = $("#barcode").val();
    $.ajax({
                url: 'getProduct.php',
                dataType: 'json',
                type: 'POST',
                data: {'Barcode':barcode},
            success: function (data) {
                if (data.products.length > 0) {
                   $(data.products).each(function(index,element){
                        $("#myTable").append("<tr><td><input type='checkbox' value='"+ element.product_id+"' />"+ element.product_id+"</td>
    <td>"+ element.product_name+"</td></tr>");
                   });
                } else {
                  alert("No Products Found");
                }  
            },
            beforeSend: function () {
                showLoader();
            },
            complete: function () {
                hideLoader();
            },
        });
 });
</script>

Step 3: your getProduct.php Code will be like this

$barcode = $_POST["Barcode"];
$query = "Select * from products WHERE ProductBarcode = $barcode";
$result = $mysqli->query($query);

if ($result->num_rows > 0) {
    $products = mysqli_fetch_all ($result, MYSQLI_ASSOC);
} else {
    $products = [];
}
echo json_encode($products);
$mysqli->close();
