WP Query Optimization Tips

$query = new WP_Query([

Your WP_Query setup looks good for fetching the latest three posts of the **location** post type. However, I have a few suggestions and improvements:

### Suggested Improvements:

1. **Ensure Pagination Works Properly:**
The `'paged' => 1` is hardcoded, which means pagination won’t dynamically work. Instead, use `get_query_var('paged')`:

'paged' => get_query_var('paged') ? get_query_var('paged') : 1,

2. **Check if Query has Results Before Outputting the Container:**
You can wrap “ inside the `if` condition to avoid rendering an empty div.

3. **Use `get_template_part` More Effectively:**
Since you're passing `$query` using `set_query_var()`, ensure that `location-post.php` is retrieving it properly using `get_query_var('query')`.

### Optimized Code:

<?php 
$paged = get_query_var('paged') ? get_query_var('paged') : 1;

$query = new WP_Query([
    'post_type'      => 'location',
    'posts_per_page' => 3,
    'orderby'        => 'date',
    'order'          => 'DESC',
    'paged'          => $paged,
]);

if( $query->have_posts() ): ?>
    <div class="location_container">
        <?php while( $query->have_posts() ): $query->the_post(); 
            set_query_var( 'query', $query );
            get_template_part('app/custom/partials/location', 'post');
        endwhile; ?>
    </div>
<?php 
endif;
wp_reset_postdata();
?>

get_template_part
Assistant
`get_template_part()` is a WordPress function used to include template files in a modular way. It helps keep your theme organized by allowing you to break up templates into reusable parts.

### **Syntax**

get_template_part( $slug, $name = null );

– **`$slug`** (Required): The base file name without the file extension.
– **`$name`** (Optional): Adds a suffix to the template file.

### **Example Usage**
#### 1. **Basic Usage**
Loads `content.php` from the theme directory.

get_template_part('content');

#### 2. **With a Second Parameter (`$name`)**
Loads `content-single.php` if it exists. Otherwise, falls back to `content.php`.

get_template_part('content', 'single');

This looks for:
– `content-single.php`
– If not found, it falls back to `content.php`

#### 3. **Using It in a Loop**
If you have a custom post type `location`, and you want to load a separate template for each post:

while ( have_posts() ) : the_post();
    get_template_part('template-parts/content', get_post_type());
endwhile;

This will look for:
– `template-parts/content-location.php` (if post type is `location`)
– Falls back to `template-parts/content.php` if not found.

### **How It Works in Your Code**
Your code:

get_template_part('app/custom/partials/location', 'post');

Will look for:
1. `app/custom/partials/location-post.php`
2. If not found, it will check `app/custom/partials/location.php`

If you need to pass additional data to the template, use `set_query_var()`:

set_query_var( 'query', $query );
get_template_part('app/custom/partials/location', 'post');

Then, inside `location-post.php`, you can retrieve it using:

$query = get_query_var('query');

show feature images if avail
Assistant
To display the **featured image** (post thumbnail) if available, modify your template file (`location-post.php`) where you're rendering the location posts.

### **Steps to Show Featured Image if Available**
1. Check if the post has a featured image using `has_post_thumbnail()`.
2. If available, display it using `the_post_thumbnail()`.
3. If not, you can show a placeholder or fallback image.

### **Updated Code for `location-post.php`**

<div class="location-post">
    <?php if ( has_post_thumbnail() ): ?>
        <div class="location-thumbnail">
            <?php the_post_thumbnail('medium'); // You can change 'medium' to 'full', 'large', or custom sizes ?>
        </div>
    <?php else: ?>
        <div class="location-thumbnail">
            <img src="<?php echo get_template_directory_uri(); ?>/assets/images/placeholder.jpg" alt="No Image Available">
        </div>
    <?php endif; ?>

    <h2><?php the_title(); ?></h2>
    <p><?php the_excerpt(); ?></p>
    <a href="<?php the_permalink(); ?>">Read More</a>
</div>

### **Explanation**
– **`has_post_thumbnail()`** β†’ Checks if the post has a featured image.
– **`the_post_thumbnail('medium')`** β†’ Displays the post's featured image at a medium size.
– **Fallback Image** β†’ Uses a placeholder image if no featured image is set.
– Ensure you have a fallback image (`placeholder.jpg`) inside `assets/images/`.

url of full feature image
Assistant
If you need the **full-size URL** of the featured image, you can use `wp_get_attachment_image_src()` instead of `the_post_thumbnail()`.

### **Get Full Featured Image URL**

<?php if ( has_post_thumbnail() ): 
    $image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), 'full' ); 
?>
    <div class="location-thumbnail">
        <img src="<?php echo esc_url( $image_url[0] ); ?>" alt="<?php the_title_attribute(); ?>">
    </div>
<?php else: ?>
    <div class="location-thumbnail">
        <img src="<?php echo get_template_directory_uri(); ?>/assets/images/placeholder.jpg" alt="No Image Available">
    </div>
<?php endif; ?>

### **Explanation**
– **`wp_get_attachment_image_src( get_post_thumbnail_id(), 'full' )`**
– Fetches the **full-size** featured image URL.
– Returns an **array** with:
– `[0]` β†’ Image URL
– `[1]` β†’ Width
– `[2]` β†’ Height
– **`esc_url( $image_url[0] )`** β†’ Escapes the image URL for security.
– **`the_title_attribute()`** β†’ Uses the post title as the `alt` attribute.

Would you like to add a `lazy loading` feature or `responsive images`? πŸš€
