我的网站上有一个附有AJAX事件的表单。在我调用wp\\u insert\\u user函数之前，AJAX事件似乎一直在运行，我不明白为什么，但当我在函数运行之前放置wp\\u send\\u json\\u success，但之后立即返回一些文本时，我收到了一个；站点未启用“；回答

下面是控制台日志

我缩短了代码，因为类非常大。

JavaScript代码：

const axios = require(\'axios\');

class campaign_submission_stage_one {

    constructor() {
        // stage one form
        const form = document.querySelector(\'form\');

        if(form){
            // process data on form submit
            form.addEventListener(\'submit\', (e) => {
                e.preventDefault();

                // passes data on to prepare method
                this._request();
            })
        }
    }

    _request(formData){
        console.log(formData)

        // needs to be "FormData" for axios to work
        const data = new FormData(from);

        // action is the function that is receiving this data
        data.append(\'action\', \'campaign_submission_stage_one\');

        // _wpnonce for form authentication
        data.append(\'_wpnonce\', formData.nonce);

        // campaign details
        data.append(\'campaign\', formData.campaign);
        data.append(\'job\', formData.job);

        // form input data
        data.append(\'first_name\', formData.first_name);
        data.append(\'last_name\', formData.last_name);
        data.append(\'email\', formData.email);
        data.append(\'password\', formData.password);

        // post the data
        axios.post(wp_obj.ajaxUrl, data)

        // response
        .then(response => {
            console.log(response);

            // error
            if(response.status === \'error\'){
                const errorMessageDiv = form.querySelector(\'.ajax-error\');
                errorMessageDiv.style.removeProperty(\'display\');
                errorMessageDiv.innerText = response.message;

            // success
            } else {
                window.location.reload(true);
            }
            
        })

        // error catching
        .catch((error) => {
            this._error(error)
        });
    }
}

new campaign_submission_stage_one();

新用户在WP Admin中显示时正在创建，但数据库中没有显示insertIntoJobApplicationsTable（）数据，因此怀疑WP\\u insert\\u用户有问题。

我有PHP错误日志，我没有看到任何错误出现。

我已经被困在这几个小时了。。。因此，如果有人能提供帮助或提示，我将非常感谢您的帮助。
