php - 显示带有来自2个输入字段的条件的表

我在显示数据库表的2种情况下的筛选表时遇到问题。

在这里，我有一个正常的完全工作表，其中显示了所有内容（我的意思是表中的所有数据，没关系）：

  <?php include("konekcija.php");?>
<?php

    global $connection;

?>

<html>
<head>
    <meta charset="UTF-8">
    <title align="center">Prikaz evidencije</title>
    <?php include("home.php"); ?>


  <div align="center" id="centar">

<input type="button" value="Štampaj evidenciju" class="btn btn-primary" onClick="document.location.href='print.php'" style="font-weight:bold;" />
</div>

<body>



   <table width="1000" border="3" align="center" style="width:80%">
       <caption style="text-align:center; font-width:bold; font-size:35px; text-align:center; font-weight:bold;">Pregled evidencije</caption>

           <tr style="background-color: #1a909e !important; font-weight: bold ; color: white !important;" align="center"; >
            <td>ID</td>
            <td>Ime studenta</td>
            <td>Prezime studenta</td>
            <td>Br. Indeksa</td>
            <td>Predmet</td>
            <td>Kolokvijum Teorija</td>
            <td>Kolokvijum Zadaci</td>
            <td>Aktivnost</td>
            <td>Prisustvo</td>
            <td>Seminarski rad</td>
            <td>Domaći rad</td>
            <td>∑ Predisp. Obaveza</td>
            <td id="heed">Obriši</td>
            <td id="heed1">Ažuriraj</td>



      </tr>



<?php
  $ViewQuery="SELECT * FROM evid_record";
  $Execute= mysqli_query($connection, $ViewQuery);

while($datarows=mysqli_fetch_array($Execute)){
      $id=$datarows['id'];
      $ime=$datarows['imes'];
      $prezime=$datarows['prezimes'];

      $semrad=$datarows['semrad'];
      $domrad=$datarows['domrad'];
      $ukupno=$datarows['ukupno'];

    ?>

<?php } ?>

</table>

我需要另一个表，用户将在其中输入“ indeksbr”（id）和“ predmet”（主题-因为我的项目是学生的考试记录），并且在提交时，他们应该得到一个过滤后的表，其中仅包含与/有关的数据他们。

到目前为止，这是我用于过滤表的代码，但是在3个小时内我没有任何结果。

<?php include("konekcija.php");?>

    global $connection;

这是另一个.php，其中有用于过滤表的输入字段：

最佳答案

当您查询"SELECT * FROM evid_record WHERE (indeksbr = '$indeksbr' AND predmet = '$predmet')";时，没有什么是$ indeksbr和$ predmet变量的线索。

我认为您的意思是$ _POST ['indeksbr']和$ _POST ['predmet'];如果这些变量是您的表单发送的数据。
