尽管传递了 'id',删除功能仍未执行
Delete function not executing despite 'id' being passed
我有这段代码可以在收据页面显示记录。
<?Php
require "config.php";
$page_name="currentout.php";
$start=$_GET['start'];
if(strlen($start) > 0 and !is_numeric($start)){
echo "Data Error";
exit;
}
$eu = ($start - 0);
$limit = 10;
$this1 = $eu + $limit;
$back = $eu - $limit;
$next = $eu + $limit;
$nume = $dbo->query("select count(id) from receipt")->fetchColumn();
echo "<TABLE class='t1'>";
echo "<tr><th>ID</th><th>Name</th><th>Pass</th><th>Amount</th><th>Action</th></tr>";
$query=" SELECT * FROM receipt limit $eu, $limit ";
foreach ($dbo->query($query) as $row) {
@$m=$i%2;
@$i=$i+1;
echo "<tr class='r$m'><td>$row[id]</td><td>$row[name]</td><td>$row[phone_num]</td><td>$row[Amount]</td><td><a href='delete.php?id=$row[id]'>delete</a></td></tr>";
}
echo "</table>";
if($nume > $limit ){
echo "<table align = 'center' width='50%'><tr><td align='left' width='30%'>";
if($back >=0) {
print "<a href='$page_name?start=$back'><font face='Verdana' size='2'>PREV</font></a>";
}
echo "</td><td align=center width='30%'>";
$i=0;
$l=1;
for($i=0;$i < $nume;$i=$i+$limit){
if($i <> $eu){
echo " <a href='$page_name?start=$i'><font face='Verdana' size='2'>$l</font></a> ";
}
else { echo "<font face='Verdana' size='4' color=red>$l</font>";}
$l=$l+1;
}
echo "</td><td align='right' width='30%'>";
if($this1 < $nume) {
print "<a href='$page_name?start=$next'><font face='Verdana' size='2'>NEXT</font></a>";}
echo "</td></tr></table>";
}
?>
这是链接的 delete.php 的代码。
<?php
require "config.php";
$pdo="null";
$sql = "DELETE FROM receipt WHERE ID= :ID";
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':ID', $_GET['id'], PDO::PARAM_INT);
$stmt->execute($sql);
echo "Record deleted successfully";
header('location: currentout.php');
?>
'id' 正在传递到删除页面,但删除功能未执行。有人可以协助发现 delete.php 中的错误吗??
您将 $pdo
设置为 'null' 然后您尝试将其用作对象。启用错误报告,您会看到相关的错误消息。
