我创建了一个库管理。我用While循环打印了图像缩略图。我可以通过复选框选择要删除的照片，然后提交表单吗。当我发送表单时，页面刷新，她运行imagesunlink（），删除行查询，但我仍然看到图像的打印行404（未找到）。如果我刷新另一个，有效！
代码：
<form name="form" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
//while loop
</form>
<?php
if (isset($_POST['delete'])) {
$delete = $_POST['select'];
foreach ($delete as $id => $val) {
$query="SELECT foto FROM gallery WHERE id = '$val'";
$result1= mysql_query($query);
while($row = mysql_fetch_assoc($result1)) {
unlink($output_dir . $row[foto]);
}
$query="DELETE FROM gallery WHERE id = '$val'";
$result2= mysql_query($query) or die (mysql_error());
}
}
sOLED。编辑：
if (isset($_POST['delete'])) {
$delete = $_POST['select'];
foreach ($delete as $id => $val) {
$query="SELECT foto FROM gallery WHERE id = '$val'";
$result1= mysql_query($query);
while($row = mysql_fetch_assoc($result1)) {
unlink($output_dir . $row[foto]);
}
$query="DELETE FROM gallery WHERE id = '$val'";
$result2= mysql_query($query) or die (mysql_error());
}
}
<form name="form" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
//while loop
</form>
您必须在php代码
您应该在HTML部分之前运行PHP代码。
试试这个：
<?php
if (isset($_POST['delete'])) {
$delete = $_POST['select'];
foreach ($delete as $id => $val) {
$query="SELECT foto FROM gallery WHERE id = '$val'";
$result1= mysql_query($query);
while($row = mysql_fetch_assoc($result1)) {
unlink($output_dir . $row[foto]);
}
$query="DELETE FROM gallery WHERE id = '$val'";
$result2= mysql_query($query) or die (mysql_error());
}
}
?>
<form name="form" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
//while loop
</form>
