制作php（WordPress）代码DRY有轻微的变化

Question

在我的single-work.php中，我有一些代码有轻微的变化，我觉得可能更干。当只有轻微的变化，这样可以重复部分代码吗？或者还有其他方法可以编写部分内容吗？     

// Advanced Custom Fields

// Grid images or videos
$grid_image_1       = get_field('image_1');
$grid_image_2       = get_field('image_2');
$grid_image_3       = get_field('image_3');
$grid_image_4       = get_field('image_4');
$grid_image_5       = get_field('image_5');


// Video embeds
$image_1_video      = get_field('image_1_do_you_wish_to_add_a_video');
$video_embed_code_1 = get_field('video_embed_code_1');

$image_2_video      = get_field('image_2_do_you_wish_to_add_a_video');
$video_embed_code_2 = get_field('video_embed_code_2');

$image_3_video      = get_field('image_3_do_you_wish_to_add_a_video');
$video_embed_code_3 = get_field('video_embed_code_3');

$image_4_video      = get_field('image_4_do_you_wish_to_add_a_video');
$video_embed_code_4 = get_field('video_embed_code_4');

$image_5_video      = get_field('image_5_do_you_wish_to_add_a_video');
$video_embed_code_5 = get_field('video_embed_code_5');


// General
$about              = get_field('about');
$subtitle           = get_field('subtitle');


get_template_part( 'template-parts/content', 'carousel' );

Answer 1

你让这段代码更干的本能是现实的。这是一个部分解决方案，演示了如何解决问题：

<?php
$numVideos = 5;

$grid_image_array       = array();
$image_video_array      = array();
$video_embed_code_array = array();

for ($i = 1; $i <= $numVideos; $i++) {
    $grid_image_array[$i]       = get_field('image_' . $i);
    $image_video_array[$i]      = get_field('image_' . $i . '_do_you_wish_to_add_a_video');
    $video_embed_code_array[$i] = get_field('video_embed_code_' . $i);
}

?>
<!-- I snipped out some of your HTML for brevity -->
<?php for ($i = 1; $i <= $numVideos; $i++): ?>    
    <div id="myModal<?= $i ?>" class="modal fade" role="dialog">
        <div class="modal-dialog">    
            <!-- Modal content-->
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal">&times;</button>
                    <h4 class="modal-title">Video</h4>
                </div>
                <div class="modal-body">
                    <iframe src=" <?php echo $video_embed_code_array[$i]; ?>" width="500" height="281" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                </div>
            </div>    
        </div>
    </div>    
<?php endfor; ?>
