Here you can use value tag of <input type="checkbox"> to put the data to user.Then you need to give a attribute 'name' to all of these check-boxes, which you can keep same and then you can grab all the selected values as an array.
Here is a changes you need to make in this code::
<table class="table table-hover table-striped">
<thead>
<tr>
<th>ID</th>
<th>Choose Product</th>
<th>Product Name</th>
<th>Product Price</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<%
String Host = "jdbc:mysql://localhost:3306/shopbilling";
Connection connection = null;
Statement statement = null;
ResultSet rs = null;
Class.forName("com.mysql.jdbc.Driver");
connection = DriverManager.getConnection(Host, "root", "");
statement = connection.createStatement();
String query = request.getParameter("q");
String data;
if(query != null)
{
data = "select * from products_tbl where product_name like '%"+query+"%' or product_price like '%"+query+"%'";
}
else
{
data = "select * from products_tbl";
}
rs = statement.executeQuery(data);
while (rs.next()) {
%>
<tr>
<td><%=rs.getString("id")%></td>
<td> <input type="checkbox" name="products" value ="<%=rs.getString("id")%>" /> </td>
<td><%=rs.getString("product_name")%></td>
<td><%=rs.getString("product_price")%></td>
<td class="text-center" width="250">
Edit
Delete
</td>
</tr>
<%
}
%>
</tbody>
</table>
Order
And while receiving the result you need to use something like this::
<%
String products[] = request.getParameterValues("products");
if (products!= null && products.length != 0) {
out.println("You have selected: ");
for (int i = 0; i < products.length; i++) {
out.println(products[i]);
}
}
%>
Hope this helped you!!
Happy Coding:)
