Find post id of CPT WordPress

Alex Miller answers:

If the user is submitting the post / form then you could make them the author of that post. If they're not already the author you can do this during the submission process.

There's 2 ways you could do this: Shortcode or Function.

Both the below methods could go into a plugin file or into the functions.php file.

Shortcode
The benefit of a shortcode is that it will allow your users to put them in them into the page editor. The shortcode could look something like this:

/**
* Display agency data by user ID
*
* Grab the current logged in user data
* [display_agency_data]
*
* Grab a specific user data
* [display_agency_data user="1"]
*
* @param Array $args
*
* @return String $html
*/
function prefix_display_agency_data_callback( $args = array() ) {

$html = '';
$user_id = get_current_user_id();

// Grab user ID if it's been passed to our shortcode
if( isset( $args['user'] ) ) {
$user_id = intval( $args['user_id'] );
}

// We do not have a user to work with.
if( empty( $user_id ) ) {
return $html;
}

/**
* Grab the single latest post of the post type where the current user is the author
*
* By grabbing the entire post object and not just the single ID, WordPress adds
* all the postmeta into the object cache.
*
* The `no_found_rows` parameter since we do not paginate.
*/
$accounts = get_posts( array(
'post_type' => 'agency_accounts',
'post_status' => 'publish',
'author' => $user_id,
'posts_per_page'=> 1,
'no_found_rows' => true,
) );

// We do not have any accounts to work with
if( empty( $accounts ) ) {
return $html;
}

// Grab the account post ID
$account_id = $accounts[0]->ID;

// Grab the business name by account post ID
$html = get_field( 'agency_business_name', $account_id );

/**
* Shortcodes return HTML instead of echoing values.
* Take advantage of PHP `ob_start()` and `ob_get_clean()` functions if necessary
*/
return $html;

}
add_shortcode( 'display_agency_data', 'prefix_display_agency_data_callback' );

You could add it into the page editor as [display_agency_data] which will grab the logged in user if it can. If you want to look for a specific user you can say [display_agency_data user="1"] where "1" is the user ID you're looking for. Finally, if you want to add this into a PHP template you can use do_shortcode( '[display_agency_data]' ); but if you plan on using it in a PHP template, use the below function example instead. It's very similar to the above.

Function

You could add the below directly into a functions.php file or a separate plugin file:

/**
* Display agency name by user ID
*
* @param Integer $user_id
*
* @return String $name
*/
function prefix_get_agency_name( $user_id = 0 ) {

$name = '';

// Grab user ID if it's been passed to our function
if( empty( $user_id ) ) {
$user_id = get_current_user_id();
}

// We do not have a user to work with.
if( empty( $user_id ) ) {
return $name;
}

/**
* Grab the single latest post of the post type where the current user is the author
*
* By grabbing the entire post object and not just the single ID, WordPress adds
* all the postmeta into the object cache.
*
* The `no_found_rows` parameter since we do not paginate.
*/
$accounts = get_posts( array(
'post_type' => 'agency_accounts',
'post_status' => 'publish',
'author' => $user_id,
'posts_per_page'=> 1,
'no_found_rows' => true,
) );

// We do not have any accounts to work with
if( empty( $accounts ) ) {
return $name;
}

// Grab the account post ID
$account_id = $accounts[0]->ID;

// Grab the business name by account post ID
$name = get_field( 'agency_business_name', $account_id );

/**
* You can modify this function however you see fit.
* This example simply returns a name.
*/
return $name;

}

You can call this directly in your PHP files either by passing a specific user ID or by default it will get the currently logged in user:

<?php
/**
* Get current user agency name
*/
echo prefix_get_agency_name();

/**
* Get agency name by user ID 1
*/
echo prefix_get_agency_name( 1 );
?>

Hopefully the above makes sense and is helpful! Otherwise, with more information I can come back and improve my answer.

hmm.. give me a minute

Tim comments:

Thank you Alex.

This works just perfectly now, both options worked, but I am using the function rather than shortcode. Thank you. Is it possible to add more ACF fields from the same ACF Agency Accounts field group to this function?

Alex Miller comments:

Now that you have the account post ID you can get whatever fields are attached to that post ID.

get_field( 'field_name', $account_id )

This is of course using the function above to get the account ID and such.
