PHP - 양식이 POST에 데이터를 저장하지 않습니다.

Question

그래서 양식에 이상한 문제가 발생했습니다. oplsaan 버튼을 클릭하면 (isset ($ _ POST [ 'opslaan']))의 코드를 실행하지 않습니다. 문제는 PHP가 $ _POST 배열에 양식 데이터를 저장하지 않는다는 것입니다. 예를 들어, 때 다음과 같은 형태로 opslaan 클릭

if(isset($_POST['wijzigen'])) 
    { 
        $query_selecteren = 'SELECT * 
             FROM contacten'; 

        $result = mysqli_query($link, $query_selecteren); 

        echo '<form id="wijzigingscherm" method="post" action="' . $_SERVER['PHP_SELF'] . '">'; 
         echo '<table> 
          <tr> 
           <th>Keuze</th> 
           <th>Afbeelding</th> 
           <th>Voornaam</th> 
           <th>Achternaam</th> 
           <th>Woonplaats</th> 
           <th>Telefoonnummer</th> 
           <th>Adres</th> 
           <th>Postcode</th> 
           <th>Opmerking</th> 
          </tr>'; 
          foreach ($result as $rij) { 
           echo '<tr>'; 
            $rijnr%2==0 ? $rijkleur='#6B9ED1' : $rijkleur='#99B3CC'; 
            echo '<td style="background-color' . $rijkleur .'"> <input type="checkbox" name="checkedUser" value="' . $rij['contact_id'] . '"/>'; 
            echo '<td style="background-color'.$rijkleur.'"> <img src="ImgPersonen/profiel.jpg"/>'; 
            echo '<td style="background-color:' . $rijkleur .'"> <input size="7" type="text" name="voornaam" placeholder="' . $rij['vnaam'] .'"/></td>'; 
            echo '<td style="background-color:' . $rijkleur .'"> <input size="7" type="text" name="achternaam" placeholder="' . $rij['anaam'] . '"</td>'; 
            echo '<td style="background-color:' . $rijkleur .'"> <input size="7" type="text" name="woonplaats" placeholder="' . $rij['wplaats'] . '"/></td>'; 
            echo '<td style="background-color:' . $rijkleur .'"> <input size="7" type="text" name="telefoonnummer" placeholder="' . $rij['tnummer'] . '"/></td>'; 
            echo '<td style="background-color:' . $rijkleur .'"> <input size="7" type="text" name="adres" placeholder="' . $rij['adres'] . '"/></td>'; 
            echo '<td style="background-color:' . $rijkleur . '"> <input size="7" type="text" name="postcode" placeholder="' . $rij['postcode'] . '"/></td>'; 
            echo '<td style="background-color:' . $rijkleur . '"> <input size="7" type="text" name="opmerking" placeholder="' . $rij['opmerking'] . '"/></td>'; 
            $rijnr++; 
           echo '</tr>'; 
          } 
         echo '</table> 
         <input type="submit" name="opslaan" style="width:15%;" value="Opslaan" /> 
         <input type="submit" name="annuleren" style="width:15%;" value="Annuleren" /> 
        </form>'; 
    } 

그것은 내가으로 session_start

if(isset($_POST['opslaan'])) 
{ 
    $query_opslaan = 'a query using the post data'; 

    mysqli_query($link, $query_opslaan) or die(mysqli_error($query_opslaan));      

    header('location:'.$_SERVER['PHP_SELF']); 
} 

아래에 위치하지만 이상한 것은 그 경우 (는 isset ($ _ POST [입니다이 코드를 실행해야합니다 'osplaan'])) 어떤 이유로 작동하지 않습니다 그리고 난 정말 내가 여기서 뭘 잘못하고 있는지 모르겠어! 누군가 내가 여기서 뭘 잘못하고 있는지 말해 줄 수 있습니까?

Answer 1

입력란 중 하나가 올바르게 닫히지 않았습니다 : achternaam 따라서 실제로 예상치 못한 결과가 나타날 수 있습니다. 아래는 대신에 시도하고 싶은 것입니다. 당신의 양식 태그는이 작업을 위해 루프 내에 중첩되어야한다
