fetch()

Fetch an item from a Pod. If $id is null, it will return the next item in the list after running find(). You can rewind the list back to the start by using reset(). Providing an $id will fetch a specific item from a Pod, much like a call to pods(), and can handle either an id or slug.

Example 1

<?php
    // We have a "books" Pod with "category" and "the_author" 
    // as single-select relationship fields, related to 
    // "categories" and "authors" Pods
    $params = array(
        'where'   => 't.name LIKE "%rings%"',
        'limit'   => -1  // Return all rows
    );

    // Create and find in one shot
    $books = pods( 'books', $params );

    if ( 0 < $books->total() ) {
        while ( $books->fetch() ) {
?>
        <h2><?php echo $books->display( 'name' ); ?></h2>
        <p>Author: <?php echo $books->display( 'the_author' ); ?></p>
        <br />
        <p>Category: <?php echo $books->display( 'category' ); ?></p>
        <br />
<?php
        } // end of books loop
    } // end of found books

The above example will output:

<h2>The Lord of the Rings</h2>
<p>Author: J. R. R. Tolkien</p>
<br />
<p>Category: Fiction</p>
<br />

Example 2

<?php
// Fetch one specific item by ID, fetch() will return non-empty if it's found.
if ( $pod->fetch( 123 ) ) {
    // We found a my_pod item with the ID 123.
}

// Fetch one specific item by slug, fetch() will return non-empty if it's found.
if ( $pod->fetch( 'my-slug' ) ) {
    // We found a my_pod item with the slug 'my-slug'.
}
