显示特定ID的数据

我一直在尝试一段时间来弄清楚如何根据ID来显示数据库中特定行的数据。显示特定ID的数据

说我想要的链接是survivaloperations.net/page/mso?p=contracts & ID =＃

其中id =＃是我从数据库中提取数据行的ID

如何使用上面显示的链接从数据库中提取和显示数据？

我试图谷歌，但真的不知道该怎么谷歌找到相关的东西

任何帮助或引用链接表示赞赏！

这是我曾尝试：

<?php 
if ($p == contracts) { 
    $id = isset($_GET['id']) ? (int)$_GET['id'] : 0; // if $_GET['id'] exists, return it as an integer, otherwise use a sentinel, id's usually start with 1, so 0 works 

if ($id != 0): 
    // I assume this is a specific news item meaning you know it's ONE result 
    $query = 'SELECT * FROM contracts WHERE id=' . $id . ' LIMIT 1'; // so try to use limit 1, no need to add extra steps in the database lookup 
endif; 

mysql_select_db('survival_contracts'); 
$result = mysql_query($query); 
//$result = mysql_query($query) or die(mysql_error()); 
// now loop through the results 
while ($row = mysql_fetch_array($result)) { 
    // and use'em however you wish 
    echo("<div class='mso_body_wrap'> 
      <div id='mso_news_container'> 
       <div class='mso_news_wrap'> 
        <div class='mso_news_top'>$row2[contract_type]</div> 
        <div class='mso_news_poster'> 
         <div class='mso_poster_avatar'><img src='images/tank.jpg'></div> 
         <div class='mso_poster_info'>for <a 
           href='#'>$row2[unit]</a><br/>by: <a 
           href='http://www.survivaloperations.net/user/$row2[userid]-$row2[username]/'>$row2[username]</a> 
         </div> 
        </div> 
        <div class='mso_news_content'> 
         <div class='mso_news_body'> 
          Callsign: $row2[callsign]<br/>

          Hours Since Lasrt Contact: $row2[contact_hours]<br/><br/>

        </div> 
        <div class='mso_news_bottom'></div> 
       </div> 
      </div>"); 
} 
?>

你必须至少尝试的东西，然后张贴在这里进行修订的建议，否则这只是一个请求代码。检查这个PHP和MySql部分：http://www.w3schools.com/php/php_mysql_select.asp – MahanGM

[**如何显示数据库中特定行的数据**]（https://www.google。 CA /搜q =如何+显示器+数据+从+ A +的具体+行+ +我+数据库中++ PHP与IE = UTF-8＆OE = UTF-8＆RLS = org.mozilla：EN-US：官方与客户端=火狐-a＆channel = np＆source = hp＆gws_rd = cr）大约有47900000个结果（0.44秒） –

我想通了我原来的代码：

if ($p == contracts) 
     {   
      $cid = $_GET['id']; // if $_GET['id'] exists, return it as an integer, otherwise use a sentinel, id's usually start with 1, so 0 works 

       $query = 'SELECT * FROM contracts WHERE id='. $cid .' LIMIT 1'; // so try to use limit 1, no need to add extra steps in the database lookup 

      mysql_select_db('survival_contracts'); 
      $result = mysql_query($query); 
      //$result = mysql_query($query) or die(mysql_error()); 
      // now loop through the results 
      while($row = mysql_fetch_array($result)){ 
       // and use'em however you wish 
       echo ("<div class='mso_body_wrap'> 
     <div id='mso_news_container'> 
      <div class='mso_news_wrap'>

       <div class='mso_news_content'>

       </div> 
       <div class='mso_news_bottom'></div>

只是一个头：mysql_ *已被弃用。更好地使用mysqli或PDO。 –

谷歌为$ _GET变量在PHP和看看数据库连接使用PDO或mysqli的

http://php.net/manual/en/mysqli.query.php

http://php.net/manual/en/pdo.query.php

添加代码后：

mysql_ *已被弃用。尝试切换到mysqli或PDO，并看看上面的链接。

$id = filter_input(INPUT_GET, 'id', FILTER_VALIDATE_INT) ? abs((int) $_GET['id']) : 0; 
if($id == 0) { 
echo 'Invalid ID'; 
return; 
} else { 
$query = "SELECT * FROM `table` WHERE `id`=". $id; 
$get = $db->prepare($query); 
if($get) { 
    $get = $db->query($query); 
    $r = $get->fetch_array(MYSQLI_ASSOC); 
    var_dump($r); 
} else { 
    echo 'Could not connect to the database'; 
    return; 
}

我混合两种风格的MySQLi，这是不是真的标准的，但它应该足够了这个例子。

（确保你有数据库连接）

$ 2行应该是$行

与事像

$row[contract_type]

最好能够

$row['contract_type']

并尝试移动到库MySQLi或PDO由以前的海报
