php - AJAX wp_insert_user WORKS but responds with "The site is not enabled"

文章数量:1290093

I have a form on my site which has an AJAX event attached. The AJAX event seems to be working up until I call the wp_insert_user function, I don't understand why but when I put a wp_send_json_success before the function it works, but straight after, even just returning some text I receieve a "The site is not enabled" response.

Below is the console log

I've shortened the code as the classes are quite large.

JavaScript code:

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;

The new user is being created as they appear in the WP Admin, but the insertIntoJobApplicationsTable() data is not appearing in the DB so suspect there is something going wrong with wp_insert_user.

I have PHP error loggin on and I am not seeing any errors appearing.

• 2 I would note even in failure it returns using wp_send_json_success, so my guess is that this is coming from the WPDB error message. It's also possible that not all paths through your classes code result in a die or exit statement, and the code outputting this message has nothing to do with this AJAX handler. Perhaps you should check the network admin and verify that the site is activated/enabled? – Tom J Nowell ♦ Commented Jun 28, 2021 at 22:19
• 1 Also is there a reason you chose to use the old admin AJAX handler instead of using a modern REST API endpoint? You'll get pretty URLs and human readable error messages – Tom J Nowell ♦ Commented Jun 28, 2021 at 22:20
• @TomJNowell Thank you Tom, I've not heard of network admin before so I will look into this. I used the old admin ajax as I inherited this project from another developer and this particular section didn't work and I couldn't figure out why, so I thought if I rewrote it into a cleaner class I could find the problem but it seems I just spent a lot of time to achieve the same outcome. – James Commented Jun 29, 2021 at 10:03
• Interestingly I made a test file that just creates a new user, no ajax or anything and it printed the same "This site is not enabled" string. The code also doesn't reach my print statements so I think this function is causing a critial error. – James Commented Jun 29, 2021 at 13:04

I decided to turn off every plugin and it turns out there was some code that had a user_register action registered to a plugin event which fired whenever a user was created, and as this code required specific data it was failing.

I disabled this action and my code is now working.
