使用 PHP 编辑多个 MySQL 行，其中所有行的主键相同

Question

我引用 URL http://www.shotdev.com/php/php-mysql/php-mysql-edit-update-data/来编辑 Z62A004B95946BB97541AFAAZ471DCCA73 表中的行页面显示良好，每行旁边都有编辑按钮。 但是，在单击任何行上的任何编辑按钮时，它会显示最后一行的输入/编辑。

发生这种情况的原因可能是因为我们的主键（自动递增）为“abc-2010-2011-1”（abc-2010-2011-2，abc-2010-2011-3）而不是 id。 其次，有多个行引用相同的主键，例如 abc-2010-2011-1。 因此，当我们尝试编辑表格中的第一行时，它会尝试编辑/显示数组最后一行的输入。

<?
$objConnect = mysql_connect("localhost","app","abc123") or die(mysql_error());
$objDB = mysql_select_db("quotation");
$serial=$objResult['serial_no'];
$parti=$objResult['particulars'];
    $qnt=$objResult['quantity'];
    $untp=$objResult['unit_price'];
$i=1;
    foreach(serial_no as $val) {
$strSQL = "SELECT * FROM table1 WHERE complete_qtn_no = '".$_GET["CusID[]"]. "' and     serial_no=$val[$i] ; ";
$objQuery = mysql_query($strSQL);
$objResult = mysql_fetch_array($objQuery);
$i++;
}
if(!$objResult)
{
    echo "Quotation number not found =".$_GET["CusID"];
}
else
{
?>

将您的查询更改为：

$strSQL = "SELECT * FROM table1 WHERE id = ".$_GET["id"];
