wordpressの高度なカスタムフィールドでPHPのelseif文が動作しない

Question

高度なカスタムフィールドを使用してコンテンツを取り込むハイブリッドグリッドを作成しました。すべてがうまくいきますが、私がWordPressの管理者のACFで設定したチェックボックスに行くif/else文を設定すると、500エラーが発生します。これは、if/elseステートメントを持つメインコードブロックです。

<div class="watcheroos"> 
    <?php 

    if(count($postslist) > 0) { ?> 

    <ul class="list-unstyled"> 

    <?php 

     $clearfix_counter = 0; 

     foreach ($new_list as $index => $post) { 

     $bkg_id = get_post_thumbnail_id($post->ID); 
     $bkg_src = wp_get_attachment_image_src($bkg_id, 'medium'); 
     $bkg_src_lg = wp_get_attachment_image_src($bkg_id, 'large'); 

     $network = get_post_meta($post->ID,'network',true); 
     $timeofday = get_post_meta($post->ID,'time_of_day',true); 
     $date = get_post_meta($post->ID,'date',true); 
     $producer = get_post_meta($post->ID,'producer',true); 


     if($index %8 == 0 || $index %9 == 0 || $index == 1) { ?>

    <?php } ?> 

私はendifを配置しています。間違った場所に？私は別の場所に配置しようとしました、どんな助けも間違いなく感謝されますようにしてください。

Answer 1

PHPの条件文のための好適な構文：

if ($foo) { 
    do_something(); 
} elseif ($bar) { 
    do_something_else(); 
} else { 
    do_nothing(); 
} 

また一並ぶことができます。

if ($foo) do_something(); 
elseif ($bar) do_something_else(); 
else do_nothing(); 

これは、一般的に、しかし、良い習慣とはみなされません。

最後に、私はマニュアルから引用しますもう一つの代替構文：「ELSEIF」は、この代替構文で一つの単語でなければならないこと

if($a > $b): 
    echo $a." is greater than ".$b; 
elseif($a == $b): // Note the combination of the words. 
    echo $a." equals ".$b; 
else: 
    echo $a." is neither greater than or equal to ".$b; 
endif; 

注意。それはほとんど使われていない。

ただし、コードの1行、;-)
