How to save for loop inside while loop variable in PHP - php

Question

I'm really having a hard time to save this loop of mine in my system i need to ask if how many style they need for example they chose 3.. there's 3 table will appear and each table you need to write in quantity..
In my saving here's my codes
$numgen = $_POST['numgen']; //number of style (i chose 3 style)
$x= 1;
while($x <= $numgen)
{
$elements = array();
foreach ($_POST['barcode'.$x] as $barcode)
{
$stmt = $db->prepare("SELECT * FROM productmaterialnumber where materialnumber = :bid");
$stmt->execute(array(':bid' => $barcode)) or die(print_r($db->errorInfo(), true));
while($row = $stmt->fetch(PDO::FETCH_ASSOC))
{
$productmaterialnumberID = $row['productmaterialnumberID'];
$matnum = $row['materialnumber'.$x];
$color = $row['color'];
$size = $row['size'];
$productgenericnumberID = $row['productgenericnumberID'];
$productstylecodeID = $row['productstylecodeID'];
$qty = $_POST[$matnum];
$totalqty += $qty;
$matnummm[] = $matnum."<br>";
$quantttt[] = $qty."<br>";
$sizzeeee[] = $size."<br>";
$colooor[] = $color."<br>";
}
$stmt = $db->prepare("INSERT INTO barcoderequest(reqID, buyerID, qty, materialnumber, ID, printstatus, division,
purrequest, dateadded, vendorID, remarks)
VALUES(:field0, :field1, :field2, :field3, :field4, :field5, :field6, :field7, :field8, :field9, :field10)");
$stmt->execute(array(':field0' => $defaultreqnum, ':field1' => $userID,
':field2' => $qty, ':field3' => $matnum, ':field4' => $ID, ':field5' => "Pending", ':field6' => $gennum.$division,
':field7' =>"Pending", ':field8' =>$currentdatetime, ':field9' => $vendor, ':field10' => $remarks))
or die(print_r($db->errorInfo(), true));
}
$x++;
}
If you notice i inserted $x beside $POST['barcode'.$x] $matnum = $row['materialnumber'.$x] so i can know the id but its not working but when i remove the $x it saves 3 times since i choose 3 style.
Can someone help me? THanks

$_POST['barcode'.$x] => not a collection so you cant loop over it.
Try this:
<?php
$_POST['numgen'] = 3;//For testing only (Needs to be removed!)
$numgen = $_POST['numgen'];
$_POST["barcode1"] = "1234566789"; //For testing only (Needs to be removed!)
$_POST["barcode2"] = "987654321"; //For testing only (Needs to be removed!)
$_POST["barcode3"] = "147852369"; //For testing only (Needs to be removed!)
$x= 1;
while($x <= $numgen)
{
foreach ($_POST as $key => $value) { //Loop over post instead of individual barcodes
$x="";
$barcode="";
if (strstr($key, 'barcode')) {
$x = str_replace('barcode', '', $key); //Get barcode number
$barcode = $value; // Get barcode
}
if ( $barcode != "") {
echo "Barcode".$x." :".$barcode."<br/>";//For testing only (Needs to be removed!)
$stmt = $db->prepare("SELECT * FROM productmaterialnumber where materialnumber = :bid");
$stmt->execute(array(':bid' => $barcode)) or die(print_r($db->errorInfo(), true));
while($row = $stmt->fetch(PDO::FETCH_ASSOC))
{
$productmaterialnumberID = $row['productmaterialnumberID'];
$matnum = $row['materialnumber'.$x];
$color = $row['color'];
$size = $row['size'];
$productgenericnumberID = $row['productgenericnumberID'];
$productstylecodeID = $row['productstylecodeID'];
$qty = $_POST[$matnum];
$totalqty += $qty;
$matnummm[] = $matnum."<br>";
$quantttt[] = $qty."<br>";
$sizzeeee[] = $size."<br>";
$colooor[] = $color."<br>";
}
$stmt = $db->prepare("INSERT INTO barcoderequest(reqID, buyerID, qty, materialnumber, ID, printstatus, division,
purrequest, dateadded, vendorID, remarks)
VALUES(:field0, :field1, :field2, :field3, :field4, :field5, :field6, :field7, :field8, :field9, :field10)");
$stmt->execute(array(':field0' => $defaultreqnum, ':field1' => $userID,
':field2' => $qty, ':field3' => $matnum, ':field4' => $ID, ':field5' => "Pending", ':field6' => $gennum.$division,
':field7' =>"Pending", ':field8' =>$currentdatetime, ':field9' => $vendor, ':field10' => $remarks))
or die(print_r($db->errorInfo(), true));
$x++;
}
}
}
