I have a very simple question: when loading a web page the Page_Load function is called so that the page can be loaded. In this function can I insert some code that allows me to select and view in the browser the data present in an external database?
This answer could be of help.
You could then write a script that fetches data from a database. How you do that is a question in it self but I can recommend checking out w3schools which is good for learning plain Javascript in the beginning.

Good day.
Could someone please tell me how I can control that a user does not enter a web application more than once?
Currently I am controlling it by storing the session that is created in php in a field of a table and through javascript using ajax I consult it every 10 seconds. I think there must be a better way ... thanks !!!
And finally solved it by validating that the session created is different from the previous one, thus updating it and the previous user wanting to validate his session in order to make any request will realize that it does not exist and this will remove him from the application .

I'm working on a web development assignment and i'm a little stuck, so i have 2 pages, the first one is formulaire.html which contains a form that sends informations to my second page which is recap.php, and in that page i have a button that must send me back to the form page with all the informations entered previously still there, i can't use any php in the first page it must remain .html, i was thinking of creating a modify.js file but i would have to get my $_SESSION variables in it, which i don't know if it's possible, if anyone can help me out it'd be great.

I'm new to this and haven't saved html form data so far.
Can someone please guide about how to save the html form elements like first name, last name, password, email to sql database using javascript or jquery?
This can't be done directly. JS is executed by the client browser, and need a middleware to allow saving the data in a MySQL DB.
Here is a link to a tutorial on how to save data to a MySQL DB
