I need to make a table of searches made by the user in php. My code fails to encapsulate every new result in the table. I'd like you not to create a new table every time and delete the data, but to gradually add to the data already in the table. Also I have a problem with highlighting accents or special characters in php, how can I fix it?

In my code I have already tried both php and js, but in both cases they conflict with the search results. I am learning web development on my own by asking many questions about my problems, I hope they are useful. My PHP code doesn't work because there isn't my table in your own.

I just don't know how to scroll and select the elements of the arrays as it always gives me undefined when I try to select an element such as 'name'.

I need that, once a specific radio input has been checked, a text area, normally disabled, return active.

I've used the jquery click(function) and removeProp but it doesn't seem to work. I'm using jquery 3.4.0, popper 1.14.7 and the latest version of bootstrap.

I have a partial HTML page that includes a search button and a table, and i want my search button to show only the results that match in the table by using keyup. Unfortunately, i inherited this project and the page that performs the search is a partial, and i can't get my JavaScript function to work with it. I've already put a src line on the main page, but once i try to insert letters into my search bar i get the following error:

at myFunction (myFunction.js:11)
at HTMLInputElement.onkeyup ((index):1)

How can i solve this?
