在.php文档中显示不同的mysql数据，如cms

Question

Hey this is probably really simple, but i am still a beginner i am a bit confused about that.. I want to create something like a selfmade CMS for my website.

I have a .php document which is querying certain data from my database. Now if i change that data, the document will display the new data. (So i can edit my texts and images..)

My actual question is, how can i create something like a new page. So that i have a form which will write new data into my database and the .php document somehow displays my new data. I mean it is the same "template" like my first .php document, but how can i query different things from my database than before? How does that work in real CMS systems?

Basically i want to write new data in my database with a form. And depending on which url i will click in my index.php, different data is shown in my page1.php document.

I hope you know what i mean. Thank you

EDIT:

To give you an example: A main document with a lot of url's named "data1" "data2" "data3" and so on. If i click on "data2" the showdata.php document should display the data2 which it will find in the database.

Answer 1

Have you tried using the data in the url to write different queries ?

Something like:

if (data1) {select data1 from database} elseif(data2){select data2 from database}

and so on ? This is what a CMS does actually it, shows different data on the same page based on the url parameters which in php you can use as $_GET['data1'] or $_REQUEST['data1']

Try something like that then update your answer with some code.
