获取值mysql计数并保存到表

Question

我在这里得到的是我的计数值并保存到我的桌子但它不起作用。我只想得到计数值，你能帮帮我吗？我会感激任何答案。显示计数没问题，但只保存在我的表中。

    <form method="POST">
        Date : <input type="text" value="<?=$p_date?>" name="datereceived" />
        <input type="submit" name="save" value="save">
    </form>

PHP

    <?        
        $sql="SELECT allinvty3.*, barcode.* ,  sample.*, count(barcode.itemcode) as icount  
    from barcode INNER JOIN sample on barcode.itemcode = sample.in_code INNER JOIN allinvty3 on 
    barcode.itemcode = allinvty3.in_code WHERE barcode.refnumber = '$temp'
 GROUP BY barcode.itemcode";

        $result = $conn->query($sql);
        while($row = $result->fetch_assoc()) {
            $icount = $row['icount'];
        }

        if(isset($_POST['save'])){
            $sql = "UPDATE barcode SET datereceived ='$p_date', actualacount = '".$icount."', status='COMPLETE' WHERE status='PENDING'";   
            $conn->query($sql) ;     
        } 
    ?>

Answer 1

因为SQL中有错误。试试这个

$sql = "UPDATE barcode SET
        datereceived ='".$p_date."' , actualacount ='".$icount."' ,
        status='COMPLETE'  WHERE status='PENDING'";
