如果不滿足第一個條件，則運行不同的 function

Question

我應該以“我對 web 開發有點陌生”作為開頭。 所以在這里..

我正在處理一個頁面，該頁面顯示數據庫中的所有結果以及誰發布了數據（如果用戶是管理員），否則，它將僅顯示用戶發布的數據而沒有“誰發布數據”行，如果用戶不是管理員。

要檢查用戶是否是管理員，我有以下代碼：

$drepturi = $conn->query("SELECT * 
                            FROM rights 
                            WHERE ID = '$loggedinuser'")
                ->fetch_object()
                ->drepturi;

這會查看一個單獨的數據庫表，其中我有 2 行，其中一行帶有登錄用戶的名稱，另一行說明他們是“管理員”還是“用戶”。

然后我有和 IF 語句后跟一個 else 取決於 $drepturi （用戶權限）是否 = 管理員/用戶：

if (($drepturi) == ("admin")) {
    $query = "SELECT * FROM formular ORDER BY $order $sort ";
    $result = mysqli_query($conn, $query);
}elseif (($drepturi) == ("user")) {
    $query = "SELECT * 
                FROM formular 
                WHERE agent ='$loggedinuser' 
                ORDER BY $order $sort ";
    $result = mysqli_query($conn, $query);
} ;

然后，根據訪問數據的用戶是"user"還是"admin" ，我在表中顯示我想要以不同方式排序的數據。

我遇到的問題是我的 function 不會根據情況而改變。

這是我為 function 編寫的腳本：

if (($drepturi) = ("admin")) {
    function myFunction() {

        var input, filter, table, tr, td, i, txtValue;
        input = document.getElementById('myInput');
        filter = input.value.toUpperCase();
        table = document.getElementById('myTable');
        tr = table.getElementsByTagName('tr');


        for (i = 0; i < tr.length; i++) {
            td = tr[i].getElementsByTagName('td')[3];
            if (td) {
                txtValue = td.textContent || td.innerText;
                if (txtValue.toUpperCase().indexOf(filter) > -1) {
                    tr[i].style.display = '';
                } else {
                    tr[i].style.display = 'none';
                }
            }
        }
    }
}else{
    function myFunction() {

        var input, filter, table, tr, td, i, txtValue;
        input = document.getElementById('myInput');
        filter = input.value.toUpperCase();
        table = document.getElementById('myTable');
        tr = table.getElementsByTagName('tr');


        for (i = 0; i < tr.length; i++) {
            td = tr[i].getElementsByTagName('td')[2];
            if (td) {
                txtValue = td.textContent || td.innerText;
                if (txtValue.toUpperCase().indexOf(filter) > -1) {
                    tr[i].style.display = '';
                } else {
                    tr[i].style.display = 'none';
                }
            }
        }
    }
}

出於某種原因，即使登錄的用戶是普通的“用戶”，過濾器也只能像 $drepturi is = "admin" 一樣工作。

編輯：如果有人看到我沒有看到的東西，我會發布整個頁面：

<?php
  include_once'header.php';
  include_once'includes/dbh.inc.php';



  if (isset($_SESSION["useruid"])){
        echo "<h1 class='welcomemsg'>Rapoarte pentru: " . $_SESSION["useruid"] . "</h1>";
      
      }
?>

      if(isset($_GET['order'])){

      }
      else {

      }

      if(isset($_GET['sort'])){
        $sort = $_GET['sort'];
      }
      else {
        $sort = 'ASC';
      }
      

      $drepturi = $conn->query("SELECT * FROM rights WHERE ID = '$loggedinuser'")->fetch_object()->drepturi;


if (($drepturi) == ("admin")) {

正如 str7 所說，答案是您不能在 javascript 中使用 php 變量。
