使用PHP / MySQL的Dynamic Bootstrap选项卡

Question

所以我现在已经解决了这个问题一段时间了，我似乎无法让它发挥作用。我的数据库中有类别表和链接。我正在尝试将“类别”标题显示为标签，将“链接”显示为我的标签内容。

让我分享一下我的代码，我会解释一下这个问题：

    <ul class="nav nav-tabs" id="lb-tabs">
  <?php $sqlCat = $db->query('SELECT `tab_title` FROM `category`'); ?>

    <?php 
  foreach ($sqlCat as $row):

      echo '<li><a href="#' . $row['tab_title'] .  '" data-toggle="tab">' .           
      $row['tab_title'] .  ' </a></li>';

  endforeach;

?> 


   </ul>

<div class="tab-content">

    <?php foreach ($sqlCat as $row2): 

    $tab = $row2['tab_title'];?>


    <div class="tab-pane active" id="<?php $row['tab_title']; ?>">

        <div class="links">

            <ul class="col">

                <?php  
                   $items = $db->prepare('SELECT u_links.title, u_links.link, u_links.tid, category.id, category.tab_title 
                   FROM u_links, category 
                   WHERE category.id = u_links.tid 
                   ORDER BY category.id ');
                $items->execute();


                while ($r = $items->fetch(PDO::FETCH_ASSOC)) {
                    echo '<li>' . $r['title'] . '</li>';
                }

                ?>

            </ul>

        </div>

    </div><!-- /tab-pane  -->



<?php endforeach; ?>



 </div>

此当前代码未在“tab-content”div中显示内容。我尝试了不同的方法，例如：

    $tab = '';
    $content = '';
    $link = '';



    $tab_title = null;

    while($row = $items->fetch(PDO::FETCH_ASSOC)) {


  $link = '<li>' . $row['title'] . '</li>';
 if ($tab_title != $row['tab_title']) {

        $tab_title = $row['tab_title'];

    $tab .= '<li><a href="#' . $row['tab_title'] .  '" data-toggle="tab">' .     
        $row['tab_title'] .  ' </a></li>';

    $content .= '<div class="tab-pane active" id="' . $row['tab_title'] .  '"><div  
        class="links"><ul class="col">' . $link . '</ul></div></div><!-- /tab-pane // 
         support -->';


   }



    }

使用这段代码，我得到太多标签（类别中的许多项目），我只想要一个标签用于许多项目（链接）。或者我每个部分只会获得一个链接，并且不会从数据库中输出该行。

如果有人可以帮我解决这个问题，我们将不胜感激！ :)谢谢。

好的，我认为问题是你如何设置.tab-pane id。现在有但没有“回声”，因此没有任何东西输出。

我整理了一个工作演示，我确实更改了代码的某些部分，但是我试图评论的是非常小的东西：

<!-- START OF YOUR CODE -->
    <ul class="nav nav-tabs" id="lb-tabs">
    <?php 
    // I just made an array with some data, since I don't have your data source
        $sqlCat =   array(
                        array('tab_title'=>'Home'),
                        array('tab_title'=>'Profile'),
                        array('tab_title'=>'Messages'),
                        array('tab_title'=>'Settings')
                    );

        //set the current tab to be the first one in the list.... or whatever one you specify
        $current_tab = $sqlCat[0]['tab_title'];
    ?>
    <?php 
    foreach ($sqlCat as $row):
        //set the class to "active" for the active tab.
        $tab_class = ($row['tab_title']==$current_tab) ? 'active' : '' ;
        echo '<li class="'.$tab_class.'"><a href="#' . urlencode($row['tab_title']) .  '" data-toggle="tab">' .           
        $row['tab_title'] .  ' </a></li>';
    endforeach;
    ?>
    </ul><!-- /nav-tabs -->
    <div class="tab-content">
        <?php foreach ($sqlCat as $row2): 
        $tab = $row2['tab_title'];
        //set the class to "active" for the active content.
        $content_class = ($tab==$current_tab) ? 'active' : '' ;
        ?>
        <div class="tab-pane <?php echo $content_class;?>" id="<?php echo $tab; //--  this right here is from yoru code, but there was no "echo" ?>">
            <div class="links">

                    <?php

                    $items = array(

              //output the links with the title that matches this content's tab.
              if($item['title'] == $tab){
                            echo '<li>' . $item['title'] . ' - '. $item['tab_link'] .'</li>';
                        }

这对我很有帮助。我有两个用于内容创建的静态选项卡，用于驱动动态选项卡。它绝对有点粗糙，但至少这个概念正在发挥作用。

<ul class="nav nav-tabs">
    <li class="active"><a href="#tab1" data-toggle="tab">Clusters</a></li>
    <li><a href="#tab2" data-toggle="tab">Activities</a></li>
    <?php           
        $sql = "<insert query here>";
        $stmt = sqlsrv_query( $conn, $sql );
        if( $stmt === false) {
            die( print_r( sqlsrv_errors(), true) );
        }

        while( $rowtab = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) {
            $tab_class = ($rowtab['tab_title']==$current_tab) ? 'active' : '' ;
            $nospaces = str_replace(' ', '', $rowtab['tab_title']);
            echo '<li class="'.$tab_class.'"><a href="#' . urlencode($nospaces) .  '" data-toggle="tab">' .
            $rowtab['tab_title'] .  '</a></li>';
        }
        ?>
</ul>
<div class="tab-content">
    <div class="tab-pane active" id="tab1">
        Tab1 Content
    </div>
    <div class="tab-pane" id="tab2">
        Tab2 Content
    </div>
    <?php           
        $sql = "<insert query here>";
        $stmt = sqlsrv_query( $conn, $sql );
        if( $stmt === false) {
            die( print_r( sqlsrv_errors(), true) );
            }

            while( $rowtab = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) {
            $tab = $rowtab['tab_title'];
            $nospaces = str_replace(' ', '', $rowtab['tab_title']);
            $content_class = ($tab==$current_tab) ? 'active' : '' ;
            echo '<div class="tab-pane'. $content_class.'" id="'.$nospaces.'">';
            echo 'You are looking at the '.$tab.' tab. Dynamic content will go here.';
            echo '</div><!-- /.tab-pane -->';
            }
            ?>
</div>
