Question

I am trying to send link id’s to a sql query in order to filter data.

When I click a link like the ones below, I want to send the id of the link to the sql query as shown below:

Example:
Links (clicked):

<p>Fitler Results</p>
<a href="#" class="category" id="marketing">Marketing</a>

<a href="#" class="category" id="automotive">Automotive</a>

(not clicked):

<a href="#" class="category" id="sports">Sports</a>

sql query – I hardcoded the id’s in, but I want it to do that automatically when someone clicks a link, in this case marketing and automotive, I want the id’s to insert automatically using jquery but have no idea how to properly do it:

$query1 = "SELECT * FROM explore WHERE category IN ('marketing', 'automotive',) ORDER BY category LIMIT $start, $limit";

Answer 1

just do a jquery ajax post with a return false, and capture the result.

$('a').click(function(){
  $.post("querypage.php", { id: "$(this).attr('id')"},
     function(data){
       dosomethingwithdata(data);
  });
 //return false to insure the page doesn't refresh
 return false;
});

Then in your php page (=querypage.php) do:

$query1 = "SELECT * FROM explore WHERE".$_POST["id"]."IN ('marketing', 'automotive',) ORDER BY category LIMIT $start, $limit";

offcourse you now have to execute the query and return the result you want.

I hope this helps, comment me if there is any problem
