嗨，这是我更新考勤系统的代码，但我不知道如何第一次插入考勤。我应该在哪里使用插入查询？它还显示错误并且不更新表。有人请指导我

<?php
    $connection=mysql_connect("localhost","root","") ordie(mysql_error()
    $db=mysql_select_db("Project") or die(mysql_error());
    $sql = "SELECT Fac_name FROM Faculty ORDER BY Fac_name ASC ";
    $result=mysql_query($sql);
    $count=mysql_num_rows($result);
?>
<form name="Attendence" method="post" action="A.php">
    <table style="text-align: left; padding: 5px;" cellpadding="0px" cellspacing="0px">
        <tbody>
            <tr>
                <th style="text-align: center; padding: 5px; border: 1px #000000 solid;">Faculty Name</th>
                <th style="text-align: center; padding: 5px; border: 1px #000000 solid;">Abesent</th>
                <th style="text-align: center; padding: 5px; border: 1px #000000 solid;">Present</th>
                <th style="text-align: center; padding: 5px; border: 1px #000000 solid;">Total present</th>
            </tr>
            <?php
                while($rows=mysql_fetch_array($result)) {

我认为您的 INSERT 查询行有语法错误，请更正。您只有三个行名 - Fac_name、date、Present、Absent，但要插入 5 个值。除此之外，引号没有正确使用

$date_value = $date[$value];
$present_value = $present[$value];
$absent_value = $absent[$value];

$check_result = mysql_query("selct count(*) from Attendence where Fac_name = '$id' AND date = '$date_value' AND Present = '$present_value' AND Absent = '$absent_value'  ");
if($check_result == 0)
{
    // insert query
}
else
{
    // update query
}
