Question

插入多个基于搜索结果的记录时出现问题。搜索字段工作正常。但问题是插入不起作用。另外，在我插入记录之前，我必须根据我的需要编辑“等级”字段。这是我的代码。

<?php
require_once('../../_includes/initialize.php');
?>


<html><br />

<form action="search.php" method="POST">
<?php
echo "<b><center>Search Results</center></b><br><br>";

if (isset($_POST['search_name'])) {

    $search_name = $_POST['search_name'];
if (!empty($search_name)) { 

$query="SELECT * FROM students WHERE course like                          '%".mysql_real_escape_string($search_name)."%'";

$result=mysql_query($query);
$num=mysql_num_rows($result);

if (($num) >=1) {
//echo 'Found.';

$i=0;
while ($i < $num) {
$id=mysql_result($result,$i,"id");
$f_name=mysql_result($result,$i,"f_name");
$g=mysql_result($result,$i,"dump");

?> 

<input name="id" type="text" value="<?php echo @$id; ?>" size="40" />
<input name="f_name" type="text" value="<?php echo @$f_name; ?>" size="40" />
<input name="a" type="text"  value="<?php echo $g; ?>" size="40" />

<br />

<?php
$i++;
}   

} else {

echo 'No results found.';
}  
}
}

?>
<?php
if (isset($_POST['Submit_Grade'])) {

$query = "INSERT INTO samplestudgrade (id, name, grade) VALUES ('".$_POST["id"]."','".$_POST["f_name"]."','".$_POST["a"]."')";
            $query_run = mysql_query($query);

            }

?>

<input name="search_name" type="text" value="search..." />
<input type="submit" value="Search"/>
<input type="submit" name="Submit_Grade" value="submit" />
</form>
</html>
