These are my databases:
database.csv:
barcode, Name , Qty ,Code
123456 ,Rothmans Blue , 40 ,RB44
234567 ,Rothmans Red , 40 ,RB30
345678 ,Rothmans Green , 40 ,RB20
456789 ,Rothmans Purple, 40 ,RB10
567890 ,Rothmans Orange, 40 ,RB55
stocktakemain.csv:
barcode, Name , Qty ,Code,ScQty
123456 ,Rothmans Blue , 40 ,RB44, 1
234567 ,Rothmans Red , 40 ,RB30, 1
Process:
The website has an input scan that is posted to "barcode".
It will check that the barcode exists within 'database.csv'
IF the barcode exists and is NOT within the 'stocktakemain.csv', it will add it to 'stocktakemain.csv' with a ScQty of 1. Please see Section 2 within code below.
ELSE when an existing barcode within stocktakemain.csv is scanned, append 'stocktakemain.csv' with +1 (an addition of 1) to ScQty for that particular line.
Bolded above is not working
Code:
function searchForBarcode($id, $array)
{
foreach ($array as $key => $val)
{
if (in_array($id, $val))
{
return $key;
}
}
return null;
}
$post = $_POST["barcode"];
$dbcsv = fopen('databases/database.csv', 'r');
$csvArray = array();
while(! feof($dbcsv))
{
$csvArray[] = fgetcsv($dbcsv);
}
fclose($dbcsv);
$searchf = searchForBarcode($post, $csvArray);
$result = $csvArray[$searchf];
$final = $result[+3];
if ($searchf !== NULL){
$stcsv = fopen('databases/stocktakemain.csv', 'r+');
$stArray = array();
while(! feof($stcsv))
{
$stArray[] = fgetcsv($stcsv);
}
fclose($stcsv);
$searchs = searchForBarcode($post, $stArray);
if ($searchs === NULL) {
$filew = 'databases/stocktakemain.csv';
$write = file_get_contents($filew);
$write .= print_r(implode(",",$result), true).",1\n";
file_put_contents($filew, $write);
}
else {
$filew = 'databases/stocktakemain.csv';
$resultexisting = $stArray[$searchs];
print_r($resultexisting);
echo "<br/>";
$getfilecont = file_get_contents($filew);
$getfilecont = trim($getfilecont);
$existing = explode(",", $getfilecont);
$existing[4] = trim($existing[4]);
++$existing[4];
print_r($existing);
echo "<br/>";
$writeto = print_r(implode(",",$existing), true);
print_r($writeto);
file_put_contents($filew, $writeto);
}
}

Answer 1

Here's some conclusions I've made from reading your code:
The else block is executed if an item is scanned that is already in the stocktakemain.csv file
$searchs contains the index of the row of the item that was scanned
$stArray contains a 2D array of the stocktakemain.csv contents - the first index is the line number, starting at 0, and the next index is the column number
Based on this, I think you need to rewrite your else block to be something like:
$scQtyColumn = 4;
// what is the current quantity?
$scQty = intval($stArray[$searchs][$scQtyColumn]);
// update the quantity in the stocktakemain.csv contents array
$stArray[$searchs][$scQtyColumn] = $scQty + 1;
// write each line to file
$output = fopen('databases/stocktakemain.csv', 'w');
foreach($stArray, $line) {
fputcsv($output, $line);
}
Could you try that out and see if it does the trick?
