1->这里用户将从计算机浏览文件，我添加了paypal按钮，所以点击paypal立即购买按钮
index.php //主页*浏览图片*表格电脑
i want to display the image by passing many page ... i am success passing the variable name (image name) but how to attach the session file name with my uploading function it will upload only session file only
... plzz help me guyzz
here are my codes
1-> page here user will browse the file from computer and i added paypal button so after clicking paypal buy now button
index.php // Main page *Browse image * form computer
<?php
session_start();
if (isset($_POST['file'])){
$file_name = $_POST['file'];
$_SESSION['file'] = $file_name;
echo "<form action=\"pay.php\" method=\"post\">\n";
echo " <input type=\"hidden\" name=\"cmd\" value=\"_s-xclick\">\n";
echo " <input type=\"hidden\" name=\"hosted_button_id\" value=\"XXX\">\n";
echo " <input type=\"image\" src=\"https://www.paypalobjects.com/en_US/i/btn/btn_buynowCC_LG.gif\" border=\"0\" name=\"submit\" alt=\"PayPal - The safer, easier way to pay online!\">\n";
echo " <img alt=\"\" border=\"0\" src=\"https://www.paypalobjects.com/en_US/i/scr/pixel.gif\" width=\"1\" height=\"1\"></form>\n";
}
?>
<form action="" method="post">
<input type="file" name="file" id="file" >
<br>
<input type="submit">
</form>
2->所以用户将收到这个页面
pay.php //付款完成
2-> so user will receive this page
pay.php // payment complete
<?php
echo "thank you we have received your payment <br> Please Follow this link to upload your file<br> <a href='image_upload.php'>Link</a>";
?>
3->主页面现在用户想要上传图像并显示它，但是如何上传在第一页中选择的图像，这样我就能成功获取文件名..但是没有得到如何用我的上传功能代码附加该文件名。 。
image_upload.php //现在上传你的照片//但是当我点击提交按钮时会话图片没有上传管道而不显示
3-> main page now user want to upload the image and display it but how upload that image which is selected in first page so i am success to getting the file name .. but not getting how to attach that file name with my upload function code ...
image_upload.php // Now upload your photo // but when i click on submit button the session image is not uploading in diectory and not displaying
