我有两个表页面和上传
PAGE:
page_id, page_name, page_parent
( 4, test, 0)
( 5, test-sub, 4)
( 6, test-sub2, 4)
UPLOAD:
upload_id, upload_name, upload_root
(1, test, 4)
(2, test-sub, 4)
(3, test-sub2, 4)
我非常成功地将page_id导入upload_root,但是当页面有子菜单并输入page_parent时出现问题。
$name = $_POST['name'];
$root = $_POST['root'];
$insert_sql = "INSERT INTO tbl_upload VALUES ('' , \"$name\", \"$root\")";
$root = $_POST['page_id'];?>
<form action="" enctype="multipart/form-data" method="post">
<div>Name: <input name="title" type="text" size="50"/></div>
<input name="page_id" type="hidden" value= "<?php echo"$page_id"; ?>"
<input type="submit" value="Upload" id="upload" class="upload"/>
</form>
$fetch_sql = "SELECT upload_id, upload_name, upload_root from tbl_upload WHERE upload_root = \"$page_id\"";
我无法获得正确的网页网址。我没有用正确的词语来描述我的问题。但我真正想要的是将page_id(自动增量)的确切值重新转换为upload_id,如果不可能的话则上传到upload_root。
UPLOAD:
upload_id, upload_name, upload_root
(4, test, 4)
(5, test-sub, 4)
(6, test-sub2, 4)
答案 0 :(得分:1)
<?php
if (isset($_GET['submit']))
{
$name = $_POST['title'];
$pageid = $_POST['page_id'];
$insert_sql = "INSERT INTO tbl_upload (upload_id, upload_name, upload_root) VALUES ('".$pageid."','".$name."','')";
mysql_query($insert_sql);
}
?>
<form action="your_page.php?submit=yes" enctype="multipart/form-data" method="post">
<div>Name: <input type="text" name="title" size="50"></div>
<input type="hidden" name="page_id" value= "<?php echo $page_id; ?>">
<input type="submit" value="Upload" id="upload" class="upload">
</form>
显然,请在页面中插入&#39; your_page.php&#39;
