PHP样式设置

Question

很高兴你来了。我需要解决方案，而且我在这些事情上是个新手。现在我的页面看起来像这样

1.text    2.text    3.text    4.text

但我需要的是这样

1.text    2.text
3.text    4.text

我拥有的代码

<table >
        <?php
        for ($x = 1; $x <= 2; $x++): ?>
        <tr>
        <?php while($row = $choices->fetch_assoc()): ?>
          <td><button class="pogaAtbilzuVarianti" value="<?php  echo $row['id_var']; ?>" id="atbilde_a"><?php  echo $row['teksts']; ?></button></td>
        <?php endwhile; ?>
        </tr>
      <?php endfor; ?>
      </table>

Answer 1

for()循环在这方面没有用处，因为它内部的while()循环将处理查询返回的每一行。

您应该只使用while循环，然后使用计数器来判断是否启动新的<tr>。

<table>
<?php
$counter = 0;
while ($row = $choices->fetch_assoc()) {
    if ($counter % 2 == 0) { // Start a new row before event elements
        echo "<tr>";
    }
    ?>
    <td><button class="pogaAtbilzuVarianti" value="<?php  echo $row['id_var']; ?>" id="atbilde_a"><?php  echo $row['teksts']; ?></button></td>
    <?php
    if ($counter % 2 == 1) { // End row after odd elements
        echo "</tr>";
    }
    $counter++;
}
if ($counter % 2 == 1) { // End last row if it only had 1 column
    echo "</tr>";
}
?>
</table>

Answer 2

<table >   
    <?php while($row = $choices->fetch_assoc()): 
    if(($row['id_var'] % 2) == 1) echo '<tr>';
    ?>
      <td><button class="pogaAtbilzuVarianti" value="<?php  echo $row['id_var']; ?>" id="atbilde_a"><?php  echo $row['teksts']; ?></button></td>
    <?php 
    if(($row['id_var'] % 2) == 0)  echo '</tr>';
    endwhile; ?>  
</table>
