Use JSONs and AJAX to access the information that u want to display. JavaScriptObjectNotation or JSON is a way you can format your files and access information that you want. [ { "Title": "Title of post", "Date" : "1/1/1990", "Content": "h, i am blog" } ] The file is saved as a ".json" and its contents are organised as objects. This video is very helpful if you are new to JSON JSON and AJAX YouTube [this video]

As Pedro already said, I suggest you should first take a look at loading all of them at once before you have them on demand. I can't really tell how far you progressed in PHP yet so I will just start explianing from where you process the query and store it in $result . First of all you don't have to prepare the HTML before hand because that doesn't work for a dynamic amount of entries, so we want to avoid hard coding wherever possible. Instead we let PHP do that for us. if ($result->num_rows > 0) { while($row = $result->fetch_assoc()) { //This gets executed for every MySQL entry } } Inside the while loop we can use just echo the entries to the HTML. The content for that we can get from $row

I have a JavaScript file linked to my main HTML file. The JavaScript file contains an AJAX request which receives some JSON data from a URL and then is supposed to log it to the console. I checked the console multiple times, but I still don't see anything. I also made sure that Log XMLHttpRequests is ticked. I use Notepad++ and the latest version of Chrome. Here is my JavaScript var ourRequest = new XMLHttpRequest(); ourRequest.open('GET',' [LINK] '); ourRequest.onload = function(){ console.log(ourRequest.responseText); }; ourRequest.send(); I'm learning from here [this video] if you wondered.

I was watching a YT video explaining JSON/AJAX ( link to video [this video] ) and in the video, the speaker uses a github.io website to link to their own JSON file ( link to file [LINK] ). Is it possible to create your own JSON file?

yes, I was trying out some JSON activities on this youtube channel ( [this video] ) and he was using an external JSON file and using a URL to call them. I would like to do the same but on the local machine using visual studio.

I'm pretty new with this JSON and AJAX staff, so I was following a tutorial on youtube: [this video] .
