Step 1: Setting up the Plugin Environment

  1. Create a new folder in your /wp-content/plugins/ directory and name it grammar-check-plugin

    Prompt
    <?php /* Plugin Name: Grammar Check Plugin Description: This plugin checks the grammar of all posts in the WordPress database. Version: 1.0 Author: Your Name Author URI: Your Website */

    LanguageTool to get your API key.

    Once you have your API key, add it in grammar-check-plugin.php:

    Prompt
    define('LANGUAGE_TOOL_API_KEY', 'your-api-key');

    Prompt
    function check_grammar($text) { $url = 'https://api.languagetoolplus.com/v2/check'; $data = array( 'text' => $text, 'language' => 'en-US' ); $options = array( 'http' => array( 'header' => "Content-type: application/x-www-form-urlencoded\r " . "Authorization: " . LANGUAGE_TOOL_API_KEY . "\r ", 'method' => 'POST', 'content' => http_build_query($data), ), ); $context = stream_context_create($options); $result = file_get_contents($url, false, $context); return json_decode($result, true); }

Prompt
function check_all_posts() { $args = array( 'post_type' => 'post', 'post_status' => 'publish', 'posts_per_page' => -1, ); $query = new WP_Query($args); if($query->have_posts()) { while($query->have_posts()) { $query->the_post(); $content = get_the_content(); $errors = check_grammar($content); if (!empty($errors['matches'])) { echo "Post ID: " . get_the_ID() . " has the following errors: "; foreach ($errors['matches'] as $error) { echo $error['message'] . "<br>"; } } } } wp_reset_postdata(); }

Prompt
function display_grammar_errors_shortcode() { ob_start(); check_all_posts(); $output = ob_get_clean(); return $output; } add_shortcode('display_grammar_errors', 'display_grammar_errors_shortcode');

Prompt
<?php /* Plugin Name: Grammar Check Plugin Description: This plugin checks the grammar of all posts in the WordPress database. Version: 1.0 Author: Your Name Author URI: Your Website */ define('LANGUAGE_TOOL_API_KEY', 'your-api-key'); function check_grammar($text) { $url = 'https://api.languagetoolplus.com/v2/check'; $data = array( 'text' => $text, 'language' => 'en-US' ); $options = array( 'http' => array( 'header' => "Content-type: application/x-www-form-urlencoded\r " . "Authorization: " . LANGUAGE_TOOL_API_KEY . "\r ", 'method' => 'POST', 'content' => http_build_query($data), ), ); $context = stream_context_create($options); $result = file_get_contents($url, false, $context); return json_decode($result, true); } function check_all_posts() { $args = array( 'post_type' => 'post', 'post_status' => 'publish', 'posts_per_page' => -1, ); $query = new WP_Query($args); if($query->have_posts()) { while($query->have_posts()) { $query->the_post(); $content = get_the_content(); $errors = check_grammar($content); if (!empty($errors['matches'])) { echo "Post ID: " . get_the_ID() . " has the following errors: "; foreach ($errors['matches'] as $error) { echo $error['message'] . "<br>"; } } } } wp_reset_postdata(); } function display_grammar_errors_shortcode() { ob_start(); check_all_posts(); $output = ob_get_clean(); return $output; } add_shortcode('display_grammar_errors', 'display_grammar_errors_shortcode');
