使用gpt生成wordpress产品标题

替换为自己的api，将下面的代码添加到主题的function.php文件中即可：

// 单个产品优化页面
function gpt_single_product_title_optimizer() {
    global $post;
    if ('product' !== $post->post_type) {
        return;
    }
    ?>
    <div class="options_group">
        <h3>Generate Optimized Title</h3>
        <textarea id="product_description" style="width:100%; height:100px;"><?php echo esc_textarea($post->post_content); ?></textarea><br>
        <button type="button" id="generate_title_button" class="button">Generate Title</button>
        <div id="generated_title"></div>
    </div>

    <script>
        jQuery(document).ready(function($) {
            $('#generate_title_button').click(function() {
                var description = $('#product_description').val();
                $.ajax({
                    url: ajaxurl,
