Wordpress：is_page（）if语句未显示内容

Question

I am trying to alter a shortcode dependent on the page which means I need to determine what page we are on and what shortcode to use.

When I try the below code the sidebar disappears completely leading me to believe that it clearly isn't working. The sidebar appears with the working shortcode when I remove the IF statement from the code however this is needed.

If you have any ideas on whats not working correctly then please feel free to shed some light on it (I have seen some similar questions however non of them have ever received answers).

<aside id="drinks-gallery" class="widget widget_gallery">
<div class="gallery-inner">
    <h3 class="widget-title">View The Gallery</h3>
    <p>Don't just take our word for it, take a look at some of our drinks!</p>
    <?php 
    if (is_page('drinks-packages')) {
        echo do_shortcode('[ngg_images source="galleries" container_ids="1" display_type="photocrati-nextgen_basic_thumbnails" override_thumbnail_settings="1" thumbnail_width="110" thumbnail_height="62" thumbnail_crop="1" images_per_page="20" number_of_columns="2" ajax_pagination="0" show_all_in_lightbox="0" use_imagebrowser_effect="0" show_slideshow_link="0" slideshow_link_text="&#91;Show slideshow&#93;" order_by="sortorder" order_direction="ASC" returns="included" maximum_entity_count="500"]')
    };?>
</div>

Answer 1

The first line of your if statement seems incorrect.

Change this:

if (is_page('drinks-packages'){

to:

if (is_page('drinks-packages')) {

and remove the last ) as well.
