Hello, as an experienced website operations expert, I know that when a website's comment form has problems, whether it is unable to submit or shows an error, it will bring a bad experience to users, and may even lead to the loss of important business leads.For AnQiCMS such an efficient and customizable Go language CMS system, although its underlying architecture is stable and reliable, we may also encounter various unexpected situations in actual operation.

Today, let's talk in detail about how to systematically investigate when you encounter the situation where the AnQiCMS message form cannot be submitted or displays an error.We will analyze from multiple dimensions such as front-end display, back-end configuration, server environment, etc., to help you quickly locate and solve problems.

When encountering difficulties in submitting or displaying anomalies in the AnQiCMS message form, how should it be investigated?

The website feedback form serves as an important bridge for communication between users and website operators, and its smooth operation is crucial.When a user tries to submit a message on a website built with AnQiCMS and finds that the form cannot be submitted or the form on the page is displayed in a chaotic or missing manner, it undoubtedly brings a lot of trouble.Don't worry, AnQiCMS provides complete functions and flexible configurations, allowing us to gradually unravel the root cause of the problem.

Step 1: Start troubleshooting from the front-end display error.

Firstly, we can start with the most intuitive phenomenon - the display issues of the front-end page.The root cause of form submission failure is often that its presentation on the page is already wrong.

1. Clear browser cache and local storageThis is a seemingly simple step that often works.After updating the website, the browser may continue to load old cached files (CSS, JavaScript, or HTML).These old files may be incompatible with the latest code of AnQiCMS, causing form display errors or functional failures.

  • Operational suggestions:When encountering problems, try to force refresh the page (Ctrl+F5 or Cmd+Shift+R) or completely clear the browser cache and Cookies.Sometimes, opening a page in incognito mode can also help you eliminate browser cache issues.

2. Check the message form template fileThe AnQiCMS template system is very flexible, the display of the message form usually depends on a specific template file, by default, it may be stored in/template/你的模板目录/guestbook/index.html.

  • Operational suggestions:
    • Confirm whether the template directory existsguestbook/index.htmlFile. If the file is missing, the form will naturally not display.
    • Check if the AnQiCMS tags in the template file are used correctly. For example, the key tag to get the form field is{% guestbook fields %}This tag will dynamically generate the form structure according to the backend settings. You need to make sure it is placed correctly.forminside the tag and the subsequentforloop can be traversed correctly.fieldsA variable, generates HTML form elements.
    • Pay attention to whether the HTML structure is complete,formIs the tag correctactionandmethodProperty. According to the AnQiCMS convention, the submission address of the message form is usually/guestbook.html.

3. Is the site basic URL configuration correct?The "Global Settings" in AnQiCMS backend has a very critical "Base URL" configuration.If this address is set incorrectly, it will cause all relative paths on the website (including CSS, JS, images, and form submission paths) to point to the wrong place.

  • Operational suggestions:Log in to the AnQiCMS backend, go to “Backend Settings” -> “Global Function Settings”, carefully check whether the “Website Address” is exactly the same as the domain name of the website you are actually visiting (including http/https). Incorrect configuration may cause the form'sactionURL error, or the captcha image cannot be loaded.

Second step: in-depth investigation of backend submission failure.

If the front-end displays normally, or even if the exception is fixed, but the form still cannot be submitted, then the problem is very likely to be in the back-end processing phase.

1. Check the back-end message management configurationAnQiCMS provides comprehensive backend management functions, and the behavior of the message form is also affected by the backend settings.

  • Operational suggestions:Log in to the AnQiCMS backend, go to "Function Management" -> "Website Message Management".
    • Check if the message list is empty. Try submitting a form and then refresh the message list. If there are no new records, it means that the submission did not reach the backend or the database write failed.
    • Check if there is a custom message field, and whether the field name submitted by the front-end form matches the field defined in the back-end completely.Any mismatch may result in the data not being stored correctly.
    • Confirm whether the message posting function is disabled, or there are other restrictive settings.

2. Investigate the CAPTCHA mechanism.The captcha is an effective means to prevent spam comments, but it is also often the 'culprit' that leads to the failure of form submission.AnQiCMS supports captcha functionality, if your website has captcha enabled, please pay special attention.

  • Operational suggestions:
    • Is the CAPTCHA enabled on the backend:?Check the 'Background Settings' -> 'Content Settings' to see if the comment/leave message captcha is enabled. If it is enabled, the frontend must provide captcha input.
    • Is the front-end captcha code correct:Refer to the AnQiCMS documentationtag-/anqiapi-other/167.htmlConfirm your template includes the correct captcha HTML and JavaScript code. This usually includes a hiddencaptcha_idfield, onecaptchaA text box and an image used to refresh the captchaimgTag, along with the corresponding JS code to fetch and display the captcha image (via/api/captchathe interface).
    • Captcha API request:Open the browser developer tools and switch to the "Network" tab. When you refresh the page or click the captcha image, you should see a link to/api/captchaThe request.
      • Check if this request returns the correct JSON data (including)captcha_idandcaptchaImage URL).
      • If the request fails (404, 500 error), it means there is a problem with the captcha backend interface or the reverse proxy configuration is incorrect.
      • If
