$result2=mysqli_query($con,$query2);
echo"<table border='2' align='center' cellpadding='0' cellspacing='0' style='width:50%'>";
echo"<tr>";
echo"<thead>";
echo"<th>"."ProductCode"."</th>";
echo"<th>"."ProductName"."</th>";
echo"<th>"."Quantity"."</th>";

                while($row=mysqli_fetch_array($result2,MYSQL_ASSOC))

echo"<tr>";
echo"<td>"."<input type='checkbox' id='chk' value='".$row['prodcode']."'name='checkbox1[]'/>".$row['prodcode']."</td>";
echo"<td>".$row['prodname']."</td>";

if(isset($_POST["btnsubmit"]))
{
$check=$_POST['checkbox1'];
$quantity=$_POST["quantity"];
 
for ($i=0; $i<sizeof($check);$i++) 
{
$query="INSERT INTO elevconfigdetails(id,prodcode,quantity)

$quantity is an array, but you treat it as string, which obviously won’t work.

@Dormilich ya the name attribute of textbox is an array..i want to insert multiple textbox values into database

[priya555]

i am having multiple checkboxes that are coming from database and i have given a field(textbox) with every checkbox...now suppose 10 checkboxes are coming from database..now i want to insert values in database only of those checkboxes which are checked along with their textbox values.in textbox user insert the quantity.when i click on submit button the checkbox values are getting inserted right but the corresponding textbox values are not getting inserted..help me to solve this problem

[Dormilich]

the problem is that there is no relation between the checkboxes and the text boxes. this is the first problem to solve.

I’d assign the text boxes using the product id. i.e.

<input type="number" min="0" name="qantity[{product-id}]" value="0">

where {product-id} is the product id.

then you can do in PHP

// using PDO for insert
foreach ($products as $id) {
    $stmt->execute([
        ':id' => $id, 
        ':quantity' => $quantities[$id],
    ]);
}

@Dormilich thanks for reply..i am new in PHP.so dont know about PDO...please tell me your suggestion in (mysqli) so it is helpfull me to understand..how i can write the insert query.??
means the id field auto-increment and the last_id field is need to repeated.so tell me that..

[Dormilich]

I find mysqli prepared statements awfully complicated, so I stick to PDO.

and for PDO you can check out the documentation: http://php.net/pdo
