如何读取mysql当前上传的php文件中记录的ID？

[英]How to read in php file upload from mysql current record the id?

问题描述

我怎样才能在下面的代码从当前记录从当前数据库中读取sob从表中articles数据字段id ，并将其写入$current_id ？

一般而言，我要更改上载文件的文件名，总是先更改“ ID2”（此ID2对于当前操作不会更改），然后更改文件名。

下面的代码仅给我$ 000000作为$ new_id

我已经有一个星期被封锁了，不知道。 我尝试了很多事情。 我读了很多。 我学到了很多东西，但没有得到结果。 令人沮丧...

这是“ body_articles.php”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);

            ?>

                if(move_uploaded_file($_FILES['file']['tmp_name'], "sobimages/" . $new_id . $_FILES['file']['name'])){
                    echo($_POST['index']);
                }
                exit(0);
            }?>

如何在不干扰其他操作的情况下从表单字段ID2获取该值，并将其读入$new_id到upload.php文件中？

最后一个文件是nextarticle.php作为示例。 它与多文件上传无关，我刚刚发布的内容是为了提供更多信息。 它读取下一条记录。 

<?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);
?>

尝试这个： 

$link = mysql_connect('parsley.arvixe.com:3306', 'admin0', 'fdhfuirkfk');
if (!$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);
}
