Synchronize wordpress with limesurvey

In my previous post, I wrote how to use wordpress functions outside.

Suppose we want to add wordpress header and footer design in limesurvey template. Following are the steps.

1. Create copy of default template in limesurvey.
2. Activate it through survey settings.
3. Now you want to upload that php file which I defined in my previous post. But when you try to upload, it gives message of not supported file system.
4. So, we need to manually upload file in template folder which is currently created.i.e limesurvey/uploads/template/copy_of_template_directory.
5. As, limesurvey template file is .pstpl format which does not support direct inclusion of php files.
6. So, the method is to call php file through AJAX function.

<div id="demo"></div>
<script type="text/javascript" charset="utf-8">
url: "{TEMPLATEURL}demo.php",
type: "POST",
success: function(result){
// Load the remote file contents into the script parent element

Above code helps to append the php code in your demo division. you can define this division where ever you want to embed the php code.


Use WordPress theme functions externally.

If you want to call any wordpress function outside , you need to have access of its wp-load.php file which load all wordpress functions.

Suppose, you want to display header and footer of wordpress website in your web browser.

1. Create index.php

2. Copy, this code to index.php file which fetch its parts.

define('WP_USE_THEMES', false);

You can call any part of wordpress like sidebar but you just need to find out its function name and call it in the required file.

I assume you got services from Digital Ocean and Dynadot and I explain further according to that. I hope you enjoy this lesson and excited for your web presence. Let’s start.

1. If you have register with Digital Ocean(hosting service provider), just login with your given credentials, now you able to see the droplet(your space dashboard). From the very first screen, IP address has been written. Just copy that IP address.

2. Login to your dynadot account. From the main menu DOMAINS go to MANAGE. Click on given name server it is like(Dynadot DNS: 012.345.678.900). After clicking, you reach to domain record page where you need to set your record type and IP address.

Just choose record type A and put IP address on the same side. Click on Save DNS.

4. Now you just mapped your DNS with IP address. It takes few hours to mapping but when it is done, you can access your server with its domain name.

5. I assume that you have basic knowledge about server login, some hosting companies provide cpanel to access your server data like bluehost. But if not you must have knowledge about ssh client.

6. Login your server with your given credentials. Place your files there and you are ready to access that files from your web browser.
