PHP页面用JS调取子窗口传值后,子窗口无法正常上传文件了
JavaScript PHP
主页面a.php,点击其中按钮后调取up.php页面,上传图片后自动关闭,并将路径信息返回给a.php上的输入框。单独调测up.php,能够上传文件并自动关闭。但是被a.php调取后,只能获取路径信息、自动关闭。但不能正确上传文件,请给与帮助,谢谢!a.php代码如下:
<script> <br /> function gg(openwindow, aa, bb) { <br /> var str = window.showModalDialog('up.php', window, "dialogWidth=500px;dialogHeight=70px;center=yes;help=no;resizable=no;status=no"); <br /> if (!str) <br /> return; <br /> document.getElementById(aa).value = str[0]; <br /> document.getElementById(bb).value = str[1]; <br /> } <br /> </script>
up.php代码如下:
$uptypes=array(
'image/jpg',
'image/jpeg',
'image/png',
'image/pjpeg',
'image/gif',
'image/bmp',
'image/x-png'
);
$max_file_size=2000000; //上传文件大小限制, 单位BYTE
$destination_folder="uploadimg/"; //上传文件路径
?>
<script> <br /> function dd(strid, strvalue) { <br /> var str = new Array(strid, strvalue); <br /> window.returnValue = str; <br /> window.close(); <br /> } <br /> </script>
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
if (!is_uploaded_file($_FILES["upfile"]['tmp_name']))
//是否存在文件
{
echo "图片不存在!";
exit;
}
$file = $_FILES["upfile"];
if($max_file_size //检查文件大小
{
echo "文件太大!";
exit;
}
if(!in_array($file["type"], $uptypes))
//检查文件类型
{
echo "文件类型不符!".$file["type"];
exit;
}
if(!file_exists($destination_folder))
{
mkdir($destination_folder);
}
$filename=$file["tmp_name"];
$image_size = getimagesize($filename);
$pinfo=pathinfo($file["name"]);
$ftype=$pinfo['extension'];
$destination = $destination_folder.time().".".$ftype;
if (file_exists($destination) && $overwrite != true)
{
echo "同名文件已经存在了";
exit;
}
if(!move_uploaded_file ($filename, $destination))
{
echo "移动文件出错";
exit;
}
}
?>
回复讨论(解决方案)
问题有俩,一个是调用子页面传值后还自动弹出一个IE窗口,这个窗口是up.php页面,我不想让他弹出,于是在up.php head标签内加上了
