  • you need to use ajax in that case Commented Apr 2, 2019 at 10:44
  • It's not entirely clear what you're trying to accomplish. But in order to send a value to your PHP code that value needs to be sent to the server. Either in a form post, or AJAX, or perhaps a query string value on a redirect. It sounds like you want the user to stay on the same page, so that would mean using AJAX. Commented Apr 2, 2019 at 10:46

I was stuck with the same problem. Resolved it with the help of jquery and ajax.

first, collect the data with the help of javascript, then send it to the desired page with the help of ajax, and then redeem it by $this->input->post() or get(), whichever way you like.

all good but i don't wanna send data to other page. i want to use this value at the same page
@SwatantraJain why do you want to do that? reason?
@Danyal Sandeelo- the value of select box 1 will help me to filter data of select box 2, so i tried it by onchange function(). value of select box 1 is successfully returned by onchange function but this value is in form of function variable[var x=document.getElementById("mediatype"); var strUser = x.options[x.selectedIndex].text; ] but i need this value in PHP variable like("$abc" variable)
you will have to make an ajax call after selecting value 1 from combo 1, get all the json of values for combox 2, set all the values to combox 2 … these are basically dependent dropdowns, the second one is dependent on 1st one.
Thank You to all for your precious help, I used an Ajax code to resolve this problem.
