我用class.upload.php制作了一个简单的上传系统，在向数据库添加新内容时效果很好。但当我需要编辑我的条目时，我有问题。在编辑条目时，我不想编辑图像，但它将其发送为空白，如果我再次选择图像，它也将其发送给空白。这是我的密码。
可以解释我的问题。
<?php require_once("conn.php");
require_once ("class.upload.php");
$catid = $_POST['catid'];
$title = $_POST['title'];
$descc = $_POST['descc'];
$keyw = $_POST['keyw'];
$message = $_POST['message'];
$Image = $_FILES['Image'];
$randnum = rand();
$foo = new upload($Image);
$filee = './Image';
if ($foo->uploaded) {
$foo->image_resize = true;
$foo->file_new_name_body = $randnum;
$foo->image_x = 550;
$foo->image_y = 440;
$foo->process($filee);
if ($foo->processed) {
echo 'Image uploaded.';
echo $foo->file_dst_name;
$foo->clean();
} else {
echo 'Error. : ' . $foo->error;
}
}
$Image7 = $foo->file_dst_name;
if($_GET[pass] == 1)
{
if(!isset($_POST[catid]) || empty($_POST[catid])){
$hata = "Required area.";
}
if(!isset($_POST[title]) || empty($_POST[title])){
$hata = "Required area.";
}
if(!isset($_POST[descc]) || empty($_POST[descc])){
$hata = "Required area.";
}
if(!isset($_POST[keyw]) || empty($_POST[keyw])){
$hata = "Required area.";
}
if(!isset($_POST[message]) || empty($_POST[message])){
$hata = "Required area.";
}
if(!$hata){
mysql_query("UPDATE product SET
catid='$_POST[catid]',
title='$_POST[title]',
descc='$_POST[descc]',
keyw='$_POST[keyw]',
message='$_POST[message]',
Image='$_POST[Image]'
WHERE id='$_POST[id]'
");
$mesaj = "OK!";
}
}
$sonuc = mysql_query("select * from product WHERE id='$_GET[product]'");
$edit = mysql_fetch_array($sonuc);
$sonuc1 = mysql_query("select * from category");
$edit1 = mysql_fetch_array($sonuc1);
?>
尝试更改更新查询
在Image='$_POST[Image]'
带有Image='$Image7'
Fatih您可以在sql查询中使用变量（即$saved_image_name）而不是$POST[image]。如果已上载数据库字段的else旧值，请将此变量设置为新名称。

$foo = new upload($Image);
$filee = './Image';
$saved_image_name = " Image "; // name of db field.
if ($foo->uploaded) {
$foo->image_resize = true;
$foo->file_new_name_body = $randnum;
$foo->image_x = 550;
$foo->image_y = 440;
$foo->process($filee);
if ($foo->processed) {
echo 'Image uploaded.';
echo $foo->file_dst_name;
// Note the quotes
$saved_image_name = " '$foo->file_dst_name' ";
$foo->clean();
} else {
echo 'Error. : ' . $foo->error;
}
}
// no use anymore $Image7 = $foo->file_dst_name;
