Nur das Ergebnis der PHP-Abfrage wird in der HTML-Tabelle angezeigt, der Rest wird außerhalb angezeigt

Question

Ich baue ein Forum für Lernzwecke. Ich entferne Forumkategorien erfolgreich aus der Datenbank und zeige sie in einer Tabelle an, aber nur die erste Kategorie wird in der Tabelle angezeigt, der Rest wird außerhalb der Tabelle angezeigt. Ich werde meinen Code und einen Screenshot des Bildes posten.

<?php 
include 'connect.php'; 
include 'header.php'; 

$sql = "SELECT categories.cat_id,categories.cat_name, 
       categories.cat_description, COUNT(topics.topic_id) AS topics 
     FROM categories 
      LEFT JOIN topics ON topics.topic_id = categories.cat_id 
     GROUP BY categories.cat_name, categories.cat_description, 
       categories.cat_id"; 

$result = mysql_query($sql); 

if(!$result) { 
    echo 'The categories could not be displayed, please try again later.'; 
} else { 
    if(mysql_num_rows($result) == 0) { 
     echo 'No categories defined yet.'; 
    } else { 
     //prepare the table 
     echo ' 
      <div class="container"> 
      <table class="table forum tale-striped table-hover"> 
      <thead> 
      <tr> 
       <th class="cell-stat"></th> 
       <th><h3>Category</h3></th> 
       <th><h3>Last topic</h3></th> 
      </tr> 
      </thead>'; 

     while($row = mysql_fetch_assoc($result)) {   
      echo '<tbody>'; 
      echo '<tr >'; 
      echo '<td class="text-center"><i class="fa fa-exclamation fa-2x text-danger">  </i></td>'; 
      echo '<td><h3><a href="category.php?id=' . $row['cat_id'] . '">' . $row['cat_name'] . '</a></h3>' . $row['cat_description'].'</td>'; 

      echo '<td class="float-xs-right">'; 

      //fetch last topic for each cat 
      $topicsql = "SELECT topic_id, topic_subject, topic_date, topic_cat 
         FROM topics 
         WHERE topic_cat = " . $row['cat_id'] . " 
         ORDER BY topic_date DESC 
         LIMIT 1"; 

      $topicsresult = mysql_query($topicsql); 

      if(!$topicsresult) { 
       echo 'Last topic could not be displayed.'; 
      } else { 
       if(mysql_num_rows($topicsresult) == 0) { 
        echo 'no topics'; 
       } else { 
        while($topicrow = mysql_fetch_assoc($topicsresult)) 
         echo '<a href="topic.php?id=' . $topicrow['topic_id'] . '">' . $topicrow['topic_subject'] . '</a> at ' . date('d-m-Y', strtotime($topicrow['topic_date'])); 
        } 
       } 
       echo '</td>'; 
       echo '</tr>'; 
       echo '</tbody>'; 
       echo '</table>'; 
       echo '</div>'; //container 
      } 
     } 
    } 

include 'footer.php'; 
?>

Answer 1

Ganz einfach haben Sie die schließende </table> Tag innerhalb der While-Schleife, also sobald die erste Zeile ausgegeben wird, schließen Sie die Tabelle. bewegen Sie sich einfach außerhalb der while-Schleife wie diese, auch die Öffnung <tbody> Bedarf über der while-Schleife zu bewegen als auch

<?php 
include 'connect.php'; 
include 'header.php'; 

$sql = "SELECT categories.cat_id,categories.cat_name, 
       categories.cat_description, COUNT(topics.topic_id) AS topics 
     FROM categories 
      LEFT JOIN topics ON topics.topic_id = categories.cat_id 
     GROUP BY categories.cat_name, categories.cat_description, 
       categories.cat_id"; 

$result = mysql_query($sql); 

if(!$result) { 
    echo 'The categories could not be displayed, please try again later.'; 
} else { 
    if(mysql_num_rows($result) == 0) { 
     echo 'No categories defined yet.'; 
    } else { 
     //prepare the table 
     echo ' 
      <div class="container"> 
      <table class="table forum tale-striped table-hover"> 
      <thead> 
      <tr> 
       <th class="cell-stat"></th> 
       <th><h3>Category</h3></th> 
       <th><h3>Last topic</h3></th> 
      </tr> 
      </thead> 
      <tbody>'; //<-- moved 

     while($row = mysql_fetch_assoc($result)) {   

      echo '<tr >'; 
      echo '<td class="text-center"><i class="fa fa-exclamation fa-2x text-danger">  </i></td>'; 
      echo '<td><h3><a href="category.php?id=' . $row['cat_id'] . '">' . $row['cat_name'] . '</a></h3>' . $row['cat_description'].'</td>'; 

      echo '<td class="float-xs-right">'; 

      //fetch last topic for each cat 
      $topicsql = "SELECT topic_id, topic_subject, topic_date, topic_cat 
         FROM topics 
         WHERE topic_cat = " . $row['cat_id'] . " 
         ORDER BY topic_date DESC 
         LIMIT 1"; 

      $topicsresult = mysql_query($topicsql); 

      if(!$topicsresult) { 
       echo 'Last topic could not be displayed.'; 
      } else { 
       if(mysql_num_rows($topicsresult) == 0) { 
        echo 'no topics'; 
       } else { 
        while($topicrow = mysql_fetch_assoc($topicsresult)) 
         echo '<a href="topic.php?id=' . $topicrow['topic_id'] . '">' . $topicrow['topic_subject'] . '</a> at ' . date('d-m-Y', strtotime($topicrow['topic_date'])); 
        } 
       } 
       echo '</td>'; 
       echo '</tr>'; 
      } 
     } 
     echo '</tbody>';   //<-- moved 
     echo '</table>';   //<-- moved 
     echo '</div>'; //container //<-- moved 

    } 

include 'footer.php'; 
?> 

Answer 2

Becuse Sie die <table> Tag im while -loop sind zu schließen. Auch sollte die <tbody> außerhalb der Schleife sein, da es nur eine <tbody> in einer Tabelle wie dieser geben sollte.
