How to pass "select" id into an ajax

Question

My ajax script

function filter(){ var input1 = $("#advanced-search1").val(); $.ajax({ dataType: 'html', url: "php/filter.php", type: "POST", data: input1, success: function(response){ $('#result').html(response); } }); }

The html form

<form> <select id="advanced-search1" name="taskOption"> <option value="apple">Apple</option> . . . </select> <input type="submit" onclick="filter()" value="Filter"> </form> <div id="result"></div>

My question is how to pass the "select" id into an ajax so that it can be processed in the other php file (filter.php)

The way data works is by using an object... What you are doing is wrong. Replace the data part with:

data: {"key": input1},

And in the server side you should be able to access it using:

$_POST["key"]

okay, and then which variable that i can carry or process in my other php file?

@nzrnfourtwenty It's like whatever you need to replace instead of the key. You can also use data like this: data: {"data": input1},

alright i got it. but can you take a look at my php file over there. I can only see a flash of "successfully here". I think there's something wrong with the if(empty.....)

@nzrnfourtwenty Haven't used filter_input(INPUT_POST, 'key', FILTER_SANITIZE_SPECIAL_CHARS);

it's okay, but do you have any idea for the php side, on how i want to make sure that the second condition will not be executed depends on submit button not from the 'key'
