回复支持票

Question

我正在创建支持票系统，现在我想知道一些事情，我无法弄清楚如何在每张票上制作回复系统。问题是我不知道如何存储回复并为每张票加载它们。 ？例如，如果票是像dashboard.php ID = 3加载我只能从是否有以它和类似的其他门票问题，这打勾ID回复，这是代码，我目前的样子：

//这是所有用户机票装载

if (!isset($_GET['action'])) 
    { 
      echo " 

      </br><div class='dashboard_info'>Dobrodosli, ovo je vas dashboard. Njegova svrha je pomaganje novim clanovima nase zajednice ali i starijima koji 
      imaju poteskoce u snalazenju sa radom User Control Panela. Koriscenjem istog imate razne opcije, ali glavna svrha ovog dela jeste resavanje raznih problema otvaranjem tiketa i slanjem upita. 
      Ispod mozete videti vase aktivne tikete ukoliko imate istih, ukoliko vam treba pomoc oko necega mozete poslati tiket klikom na Novi Tiket.</div> 

      </br></br></br><center> 
      <div class='dataTables'> 

       <table> 
       <tr> 
         <td CLASS='MYTABLE'>Naslov Tiketa</td> 
         <td CLASS='MYTABLE'>#ID Tiketa</td> 
         <td CLASS='MYTABLE'>Status Tiketa</td> 
         <td CLASS='MYTABLE'>Vrsta Tiketa</td> 
         <td CLASS='MYTABLE'>Datum</td> 
         </tr> 

      </center> 
"; 
      $username = $_COOKIE['username']; 
      $author = mysqli_real_escape_string($con, $username); 
      $query = "SELECT * FROM Dashboard WHERE Postavio = '$author'"; 
      $result = mysqli_query($con,$query); 

      while($row = mysqli_fetch_array($result,MYSQLI_ASSOC)) 
      { 
       $ID = clear($row['ID']); 
       $Naslov = clear($row['Naslov']); 
       $Status = clear($row['Status']); 
       $Vrsta = clear($row['Vrsta']); 
       $Datum = clear($row['Datum']); 

       if($Status == 0) { $statusinfo = "Otvoren"; } 
       else if($Status == 1) { $statusinfo = "Zatvoren"; } 
       else if($Status == 2) { $statusinfo = "Odgovoren"; } 

       echo " 

        <tr CLASS='MYTABLE'> 
        <td CLASS='MYTABLE'><a href='dashboard.php?id=$ID'>$Naslov</a></td> 
        <td CLASS='MYTABLE'><a href='dashboard.php?id=$ID'>#0000$ID</a></td> 
        <td CLASS='MYTABLE'>$statusinfo</td> 
        <td CLASS='MYTABLE'>$Vrsta</td> 
        <td CLASS='MYTABLE'>$Datum</td> 
        <tr> 

        ";  
       } 
     } 

//这是网页加载ID为

if(isset($_GET['id'])) 
    { 
     $id = clear($_GET['id']); 
     $user = mysqli_real_escape_string($con, $_COOKIE['username']); 
     $query = "SELECT * FROM `dashboard` WHERE `Postavio` = '$username' AND `ID` = '$id'"; 
     mysqli_query($con, $query); 
     $output = mysqli_num_rows($result); 

     if($output == 0) 
     { 
      echo "Vi ste vlasnik ovog ticketa"; 
      exit(); 
     } 
     else 
     { 
      echo "Vi niste vlasnik ovog ticketa"; 
     } 
    } 

但这并不工作做好，甚至，它应该从以下网址获得ID并把它比作一个数据库并查看它是否由用户创建，并且由其他人创建并返回h即时到主页面。

Answer 1

...它应该从以下网址获得ID和数据库做比较，看看是否它是由用户进行，并且比它应该他返回到主页如果由其他人做。

在这里看看这些语句，

$id = clear($_GET['id']); 
$user = mysqli_real_escape_string($con, $_COOKIE['username']); 
$query = "SELECT * FROM `dashboard` WHERE `Postavio` = '$username' AND `ID` = '$id'"; 
                  ^it should be $user 
mysqli_query($con, $query); 
^ You're not storing the result set. 

首先将结果存储在一个变量设置，然后用mysqli_num_rows()功能。

所以，你的代码应该是这样的：

// your code 

$query = "SELECT * FROM `dashboard` WHERE `Postavio` = '$user' AND `ID` = '$id'"; 
$result = mysqli_query($con, $query); 
$output = mysqli_num_rows($result); 

if($output){  
    // You are the owner of this ticket 
    echo "Vi ste vlasnik ovog ticketa"; 
}else{ 
    // redirect the user to main page 
    header("Location: mainpage.php"); 
    exit(); 
} 

// your code
