Question

我想在page.php的Wordpress ACF选项中添加另一个横幅图片。我想这样做，所以我可以为默认的Wordpress模板创建默认横幅图像。我不知道该怎么做。

<?php if (is_page_template('template-projects.php')) { ?>

    <?php
     $banimage2 = get_field('banner_img', 'options'); // Array returned by Advanced Custom Fields
     $banimage2Alt = $banimage2['alt']; // Grab, from the array, the 'alt'
     $banimage2Width = $banimage2['width']; // Grab, from the array, the 'width'
     $banimage2Height = $banimage2['height']; // Grab, from the array, the 'height'
     $banimage2ThumbURL = $banimage2['sizes']['large']; //grab from the array, the 'sizes', and from it, the 'thumbnail'
    ?>

    <img class="box-banner" src="<?php echo $banimage2ThumbURL;?>"  alt="<?php echo $banimage2Alt; ?>"  width="<?php echo $banimage2Width; ?>" height="<?php echo $banimage2Height; ?>" />

<?php } elseif (is_singular('projects')) { ?>

    <?php
     $banimage3 = get_field('pd_banner', $post_id); // Array returned by Advanced Custom Fields
     $banimage3Alt = $banimage3['alt']; // Grab, from the array, the 'alt'
     $banimage3Width = $banimage3['width']; // Grab, from the array, the 'width'
     $banimage3Height = $banimage3['height']; // Grab, from the array, the 'height'
     $banimage3ThumbURL = $banimage3['sizes']['large']; //grab from the array, the 'sizes', and from it, the 'thumbnail'
    ?>

    <img class="box-banner" src="<?php echo $banimage3ThumbURL;?>"  alt="<?php echo $banimage3Alt; ?>"  width="<?php echo $banimage3Width; ?>" height="<?php echo $banimage3Height; ?>" />

<?php } else { ?>
    <?php
     $banimage = get_field('banner_img'); // Array returned by Advanced Custom Fields
     $banimageAlt = $banimage['alt']; // Grab, from the array, the 'alt'
     $banimageWidth = $banimage['width']; // Grab, from the array, the 'width'
     $banimageHeight = $banimage['height']; // Grab, from the array, the 'height'
     $banimageThumbURL = $banimage['sizes']['large']; //grab from the array, the 'sizes', and from it, the 'thumbnail'
    ?>
    <?php if(get_field('banner_img')): ?>
    <img class="box-banner" src="<?php echo $banimageThumbURL;?>"  alt="<?php echo $banimageAlt; ?>"  width="<?php echo $banimageWidth; ?>"  height="<?php echo $banimageHeight; ?>" />
    <?php endif; ?>
<?php } ?>

Answer 1

我不确定我完全想要做什么，但要在if else声明中添加新条件，您可以像这样添加：

[...]

<?php elseif (is_singular('projects')) : ?>

   [...]

<?php elseif ( [YOUR CONDITION] ) : ?>

   [DO YOUR THING]

<?php else : ?>

   [...]

<?php endif; ?>

Answer 2

我的回答是在声明的底部添加一个额外的ELSE。

<?php else: ?>
    <img class="box-banner" src="<?php the_field('banner_img', 'options' ); ?>" />

<?php endif; ?>

如何在我的elseif语句中添加另一个ACF选项？
