You almost certainly have PHP scripts that do somewhat numerous jobs, similar to cleaning up orphaned publish metadata or deleting expired transients. Over time, that collection grows and lives in a theme document, a plugin folder, or a tucked-away checklist. Acorn helps to rein in this disorganization thru bringing Laravel’s Artisan Console to WordPress.

This means you’ll assemble custom designed WP-CLI directions with structured class information that centralize your upkeep not unusual sense. The ones directions run repeatedly all the way through building, staging, and production the usage of building indicators, formatted table output, right kind error coping with, and additional. You’ll then purpose them by means of SSH, time table them with cron jobs, or execute them all through deployments.

Find out how to arrange Acorn and run directions

The first step is to position within the dependencies you wish to have. Acorn needs PHP 8.2 or higher, Composer for managing dependencies, and WP-CLI working on your server. Kinsta accommodates WP-CLI on all hosting plans, so that you’ll get began building directions straight away.

You installed Acorn by way of Composer the usage of composer require roots/acorn all the way through the endeavor root. Then add boot code to each your theme’s functions.php document or your main plugin document:

 'https://roots.io/acorn/scientific docs/arrange/',
            'link_text' => __('Acorn Medical doctors: Arrange', 'house'),
        ]
    );
}

add_action('after_setup_theme', function () {
    Software::configure()
        ->withProviders([
            AppProvidersThemeServiceProvider::class,
        ])
        ->boot();
}, 0);

The zero-config setup stores software cache and logs throughout the WordPress cache listing at [wp-content]/cache/acorn/, in conjunction with your directions living throughout the theme’s app/ checklist.

The usual building follows Laravel conventions, similar to trustworthy directories for app/, config/, storage/, and belongings/ at your endeavor root. You put this up with one line:

wp acorn acorn:init storage && wp acorn supplier:submit --tag=acorn

Should you run wp acorn document, this verifies your arrange thru appearing the entire available Acorn directions. From this stage, all custom designed directions you create are stored throughout the app/Console/Directions/ checklist. Acorn automatically discovers any command classes in this location and registers them with WP-CLI.

Rising your first Artisan command

The wp acorn make:command CleanupCommand Artisan command generates your document with the development you wish to have. It incorporates 3 key portions that every Artisan command needs:

• A $signature assets that defines your command identify and alternatives.
• The $description assets for have the same opinion text.
• A handle() approach where your command not unusual sense lives.

In this case, it builds app/Console/Directions/CleanupCommand.php with a elementary command building:

<?php
namespace AppConsoleCommands;
use IlluminateConsoleCommand;
class CleanupCommand extends Command
{
    protected $signature = 'app:cleanup';
    protected $description = 'Command description';
    public function handle()
    {
        //
    }
}

The $signature assets uses a selected syntax:

• A elementary command most effective needs a name, similar to cleanup:run.
• You add required arguments thru wrapping them in curly braces (cleanup:run {days}, for example).
• No longer mandatory arguments get a question mark: cleanup:run {days?}.
• Possible choices use double dashes: cleanup:run {--force} {--limit=100}.

Next, include an overview for the command and your elementary not unusual sense:

protected $signature = 'cleanup:test {--dry-run : Preview changes without executing}';
protected $description = 'Take a look at cleanup command';
public function handle()
{
    $dryRun = $this->chance('dry-run');

    if ($dryRun) {
        $this->components->information('Working in dry-run mode');
    }

    $this->components->information('Cleanup command carried out');

    return 0;
}

You’ll be able to test this the usage of wp acorn cleanup:test --dry-run. The command outputs formatted messages the usage of Artisan’s section system. The $this->components->information() approach shows success messages in green. You’ll be able to moreover use $this->components->error() for errors, $this->components->warn() for warnings, and $this->line() for simple text output.

Find out how to assemble 3 good upkeep directions

Listed here are some examples that mean you can tackle database upkeep tasks that rise up for numerous WordPress internet websites.

While each command accommodates error coping with and largely follows WordPress coding necessities to stick your data protected, you will have to nevertheless use the ones as a skeleton for your private duties moderately than simply copy-paste them.

1. Cleaning orphaned publish metadata

Publish metadata sticks spherical after you delete posts. This happens when plugins bypass WordPress’s deletion hooks and leave metadata entries pointing to posts that no longer exist. Over time, this bloat slows down your database queries.

In case you create the command with wp acorn make:command CleanupOrphanedMeta, you’ll be able to get began with the command class building and signature:

chance('dry-run');

        $this->components->information('Scanning for orphaned publish metadata...');

The command uses a LEFT JOIN query to look out the ones orphaned information. The improvement exams for NULL values throughout the posts table. If the join returns NULL the metadata belongs to a deleted publish:

        // To seek out orphaned metadata
        $orphans = $wpdb->get_results("
            SELECT pm.meta_id, pm.post_id, pm.meta_key 
            FROM {$wpdb->postmeta} pm
            LEFT JOIN {$wpdb->posts} p ON pm.post_id = p.ID
            WHERE p.ID IS NULL
            LIMIT 1000
        ");

        if (empty($orphans)) {
            $this->components->information('No orphaned metadata came upon');
            return 0;
        }

When the command finds orphans, it shows you a depend and samples a few information will have to you’re in dry-run mode. You need to ensure what’s getting deleted previous than you commit:

        $depend = depend($orphans);
        $this->components->warn("Came upon {$depend} orphaned metadata information");
        if ($dryRun) {
            $this->newLine();
            $this->line('Trend orphaned information:');

            foreach (array_slice($orphans, 0, 5) as $orphan) {
                $this->line("  → Post ID {$orphan->post_id}: {$orphan->meta_key}");
            }

            return 0;
        }

The true deletion uses $wpdb->get in a position() to avoid SQL injection attacks. The command processes 1,000 information at a time, which prevents memory problems on internet sites with tens of hundreds of thousands of metadata entries:

        // Delete orphaned information
        $metaIds = array_map(function($orphan) {
            return $orphan->meta_id;
        }, $orphans);

        $placeholders = implode(',', array_fill(0, depend($metaIds), '%d'));

        $deleted = $wpdb->query(
            $wpdb->get in a position(
                "DELETE FROM {$wpdb->postmeta} WHERE meta_id IN ({$placeholders})",
                ...$metaIds
            )
        );

        if ($deleted === false) {
            $this->components->error('Did not delete orphaned metadata');
            return 1;
        }

        $this->components->information("Deleted {$deleted} orphaned metadata information");
        return 0;
    }
}

To run the command, use wp acorn upkeep:cleanup-orphaned-meta --dry-run.

2. Deleting expired transients

WordPress stores transients in wp_options with expiration dates. While a daily cron task cleans the ones up, you once in a while wish to run a information cleanup all through upkeep house home windows or when transient bloat becomes a subject matter.

After you generate the command with wp acorn make:command CleanupTransients, you’ll be able to prepare the command building:

components->information('Deleting expired transients...');

This deletion query uses multi-table DELETE syntax to remove every the transient and its timeout chance at once. The query finds timeout information where the expiration timestamp has passed:

        // Delete expired not unusual transients
        $deleted = $wpdb->query(
            $wpdb->get in a position(
                "DELETE a, b FROM {$wpdb->alternatives} a, {$wpdb->alternatives} b
                WHERE a.option_name LIKE %s
                AND a.option_name NOT LIKE %s
                AND b.option_name = CONCAT('_transient_timeout_', SUBSTRING(a.option_name, 12))
                AND b.option_value esc_like('_transient_') . '%',
                $wpdb->esc_like('_transient_timeout_') . '%',
                time()
            )
        );

Moreover take a look at for errors and apply the deletion depend:

        if ($deleted === false) {
            $this->components->error('Did not delete transients');
            return 1;
        }

        $transientCount = $deleted;

On Multisite installations, the command runs a second query for internet web page transients. The ones use different table prefixes alternatively observe the an identical deletion building:

        // Delete expired internet web page transients (multisite)
        if (is_multisite()) {
            $siteDeleted = $wpdb->query(
                $wpdb->get in a position(
                    "DELETE a, b FROM {$wpdb->alternatives} a, {$wpdb->alternatives} b
                    WHERE a.option_name LIKE %s
                    AND a.option_name NOT LIKE %s
                    AND b.option_name = CONCAT('_site_transient_timeout_', SUBSTRING(a.option_name, 17))
                    AND b.option_value esc_like('_site_transient_') . '%',
                    $wpdb->esc_like('_site_transient_timeout_') . '%',
                    time()
                )
            );

            if ($siteDeleted !== false) {
                $transientCount += $siteDeleted;
            }
        }

        $this->components->information("Deleted {$transientCount} expired transients");

        return 0;
    }
}

To execute the command, run wp acorn upkeep:cleanup-transients.

3. Auditing autoloaded alternatives

Autoloaded choices load on every request your WordPress internet web page handles. You’ll be able to start to see slowdowns and memory consumption spikes when this knowledge crosses 1MB. This command finds your biggest autoloaded alternatives so you’ll be able to apply down which plugins goal the bloat.

First, create the audit command with wp acorn make:command AuditAutoload. Then, define the command signature with a configurable threshold:

chance('threshold');

        $this->components->information('Calculating autoloaded alternatives size...');

From proper right here, calculate the overall size of all autoloaded alternatives:

        // Get total autoload size
        $result = $wpdb->get_row(
            "SELECT 
                SUM(LENGTH(option_value)) as total_bytes,
                COUNT(*) as total_count
            FROM {$wpdb->alternatives}
            WHERE autoload = 'certain'"
        );

        $totalBytes = (int) $result->total_bytes;
        $totalCount = (int) $result->total_count;
        $totalMb = round($totalBytes / 1024 / 1024, 2);

        $this->newLine();
        $this->line("General autoloaded: {$totalMb} MB ({$totalCount} alternatives)");

The command runs a query for alternatives above your threshold, sorts them thru size, and bounds results to the most important 20:

        // Get biggest autoloaded alternatives
        $largeOptions = $wpdb->get_results(
            $wpdb->get in a position(
                "SELECT option_name, LENGTH(option_value) as size_bytes
                FROM {$wpdb->alternatives}
                WHERE autoload = 'certain'
                AND LENGTH(option_value) > %d
                ORDER BY size_bytes DESC
                LIMIT 20",
                $threshold
            )
        );

        if (empty($largeOptions)) {
            $this->components->information('No alternatives exceed the threshold');
            return 0;
        }

Artisan’s $this->table() approach formats the ones results as an ASCII table: finding out tabular data on your terminal beats parsing the raw query output:

        $this->newLine();
        $this->components->warn('Large autoloaded alternatives:');
        $this->newLine();

        $tableData = [];

        foreach ($largeOptions as $chance) {
            $sizeKb = round($option->size_bytes / 1024, 2);
            $tableData[] = [
                $option->option_name,
                $sizeKb . ' KB'
            ];
        }

        $this->table(
            ['Option Name', 'Size'],
            $tableData
        );

The command throws a warning when the overall autoload crosses 3MB, which indicates a potency problem you wish to have to handle:

        if ($totalBytes > 3000000) {
            $this->newLine();
            $this->components->error('Warning: General autoload exceeds 3MB');
        }

        return 0;
    }
}

To run the audit, use wp acorn upkeep:audit-autoload --threshold=500000.

Find out how to get right to use WordPress data within directions

WordPress functions art work inside your command methods because of Acorn boots within WordPress’s lifecycle. This means you’ll be able to title some functions similar to get_posts() or get_option() without any explicit setup:

public function handle()
{
    $posts = get_posts([
        'post_type' => 'post',
        'post_status' => 'publish',
        'numberposts' => 10,
    ]);

    foreach ($posts as $publish) {
        $this->line($post->post_title);
    }

    return 0;
}

For direct database queries, declare the $wpdb world in the beginning of your approach:

public function handle()
{
    world $wpdb;   

    $depend = $wpdb->get_var(
        "SELECT COUNT(*) FROM {$wpdb->posts} WHERE post_status = 'submit'"
    );

    $this->line("Published posts: {$depend}");

    return 0;
}

$wpdb->get in a position() is best on each instance your queries include variables or client input as a result of it’s serving to to stop SQL injection attacks:

$status = 'submit';
$postType = 'publish';
$results = $wpdb->get_results(
    $wpdb->get in a position(
        "SELECT ID, post_title FROM {$wpdb->posts} 
        WHERE post_status = %s AND post_type = %s",
        $status,
        $postType
    )
);

Should you test for false after any database operations, this will have to mean you can catch errors:

$up-to-the-minute = $wpdb->substitute(
    $wpdb->posts,
    ['post_status' => 'draft'],
    ['ID' => 123],
    ['%s'],
    ['%d']
);

if ($up-to-the-minute === false) {
    $this->components->error('Database substitute failed');
    return 1;
}

Customized submit varieties and taxonomies art work by way of same old WordPress functions:

$words = get_terms([
    'taxonomy' => 'category',
    'hide_empty' => false,
]);

foreach ($words as $period of time) {
    wp_update_term($term->term_id, 'elegance', [
        'description' => 'Updated via command',
    ]);
}

Custom designed WP-CLI directions are simple with Acorn and Artisan Console

Acorn means that you can get right to use Laravel’s structured command classes, formatted output elements, right kind error coping with, and additional, while supplying you with entire get right to use to WordPress’ functions and knowledge.
