如何从表sob数据字段articles中的当前数据库id的当前记录中读取以下代码并将其写入$current_id？
一般来说，我想更改上传文件的文件名，总是首先是＆＃34; ID2＆＃34; （此ID2不会更改当前操作），然后是文件名。
以下代码仅为$ new_id
提供了000000
我因为一周被封锁而且不知道。我尝试了很多东西。我读了这么多。我学到了很多，但我没有得到结果。令人沮丧......
这是＆＃34; body_articles.php＆＃34;
中的html代码 <?php session_start();
$_db_host = "localhost";
$_db_username = "admin0";
$_db_passwort = "dfgfghxyxc";
$_db_datenbank = "sob";
# Verbindung zur Datenbank herstellen
$_link = mysql_connect($_db_host, $_db_username, $_db_passwort);
# Pr�fen ob die Verbindung geklappt hat
if (!$_link)
{
# Nein, also das ganze Skript abbrechen !
die("Keine Verbindung zur Datenbank m�glich: " .
mysql_error());
}
# Datenbank ausw�hlen
mysql_select_db($_db_datenbank, $_link);
?>

如何从表单字段ID2获取值，将此值读入$new_id upload.php文件而不干扰其他操作？
最后一个文件是nextarticle.php。它与多文件上载无关，我发帖就是提供更多信息。它读了下一张唱片。
<?php
$link = mysql_connect('localhost', 'admin0', 'fdhfuirkfk');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db('sob', $link);
if (!$db_selected) {
die('Can\'t use foo : ' . mysql_error());
}
$current_id = $_REQUEST['currentRecord'];
$result = mysql_query("SELECT * FROM articles WHERE id > " . $current_id . " ORDER BY id ASC LIMIT 1");
$result = mysql_fetch_row($result);
echo json_encode($result);
?>
答案 0 :(得分：1)
试试这个：
$link = mysql_connect('parsley.arvixe.com:3306', 'admin0', 'fdhfuirkfk');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db('sob', $link);
if (!$db_selected) {
die('Can\'t use foo : ' . mysql_error());
}
$current_id = (int)$_REQUEST['currentRecord']; // here is Your current_id
// if You're just getting data so You echo result from db
if($_SERVER['REQUEST_METHOD'] == "GET"){
$result = mysql_query("SELECT * FROM articles WHERE id > " . $current_id . " ORDER BY id ASC LIMIT 1");
$result = mysql_fetch_row($result);
echo json_encode($result);
exit(0);
}
// and there You're pushing file and echo $_POST['index']
if($_SERVER['REQUEST_METHOD'] == "POST"){
$new_id = sprintf( "%06d", $current_id);
if(move_uploaded_file($_FILES['file']['tmp_name'], "sobimages/" . $new_id . $_FILES['file']['name'])){
echo($_POST['index']);
}
exit(0);
}
