如何从mysqli fetch数组中打印出特定次数的tab内容？

Question

所以我想做的是在一列中打印三次来自 mysqli_fetch_array 的选项卡内容，然后移动到第二列，然后是第三列。

<div class="d-flex justify-content-center">

    <!-- First column -->

    <div class="d-flex flex-column">

        <?php echo $tab_content; ?>

    </div>

    <!-- Second column -->

    <div class="d-flex flex-column">

    </div>

    <!-- Third column -->

    <div class="d-flex flex-column">

    </div>
</div>

和php

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

$tab_content .= '
<div class="card" style="width: 20rem;">

<img class="card-img-top" src="">
<div class="card-body">
<h4 class="card-title">'.$row['job_name'].'</h4>
<h6 class="card-subtitle mb-2">'.$row['price'].'</h6>
<p class="card-text">'.$row['job_desc'].'</p>
<a href="#" class="btn btn-primary">Contact</a>
</div>
</div>
';
}

这就是我要实现的目标

Answer 1

尝试以下操作（在您的 PHP 文件中）：

$i=1;
$tabs = [];
$tab_content = null;
while ($row = mysqli_fetch_array($result)) {
$tab_content .= '
<div class="card" style="width: 20rem;">

<img class="card-img-top" src="">
<div class="card-body">
<h4 class="card-title">'.$row['job_name'].'</h4>
<h6 class="card-subtitle mb-2">'.$row['price'].'</h6>
<p class="card-text">'.$row['job_desc'].'</p>
<a href="#" class="btn btn-primary">Contact</a>
</div>
</div>
';
if($i % 3 === 0)
{
    $tabs[] = $tab_content;
    $tab_content = null;
}
$i++;
}

$tab_content = '<div class="d-flex flex-column">' . implode('</div><div class="d-flex flex-column">', $tabs) . '</div>';

在你的 HTML 中：

<div class="d-flex justify-content-center">
        <?php echo $tab_content; ?>
</div>

这会将每个列的帖子存储为值，然后使用 implode() 将它们转换为 html 字符串，同时连接其中的 html 标签。并添加前缀和后缀 div 标记。

Answer 2

你的 Php 代码是这样的，While 循环只先 Div 然后显示动态：

工作演示：http://phpfiddle.org/main/code/4msw-ep80

注意：我在 while 循环中使用数组显示数据。

<?php

$a = array(
  array(
    'job' => 'job 1',
    'price' => '500',
    'job_desc' => 'Bla Bla Bla',
  ),
  array(
    'job' => 'job 2',
    'price' => '1000',
    'job_desc' => 'Bla Bla Bla',
  ),
  array(
    'job' => 'job 3',
    'price' => '2000',
    'job_desc' => 'Bla Bla Bla',
  ),

  array(
    'job' => 'job 4',
    'price' => '500',
    'job_desc' => 'Bla Bla Bla',
  ),
  array(
    'job' => 'job 5',
    'price' => '1000',
    'job_desc' => 'Bla Bla Bla',
  ),
  array(
    'job' => 'job 6',
    'price' => '2000',
    'job_desc' => 'Bla Bla Bla',
  ),
  array(
    'job' => 'job 7',
    'price' => '500',
    'job_desc' => 'Bla Bla Bla',
  ),
  array(
    'job' => 'job 8',
    'price' => '1000',
    'job_desc' => 'Bla Bla Bla',
  ),
  array(
    'job' => 'job 9',
    'price' => '2000',
    'job_desc' => 'Bla Bla Bla',
  )

);

?>
