javascript - Fetch from MySQL with AJAX -


i'm building web application connects database has got couple of variables stored that's necessary site function properly.

right i'm using php connect , fetch information in end easier use .html file, i'm planning on using ajax fetch information instead.

i've got code:

$(function ()    {      $.ajax({                                         url: 'api.php',                     data: {         paramname: $("#partyidinput").val()     },   method: post,                      datatype: 'json',               success: function(data)                {         var id = data[0];                var pid = data[1];               var ploc = data[2];               var pname = data[3];          var pformid = data[5];              var pformsong = data[6];               var pformartist = data[7];                var pformname = data[8];              $('#partytitle').append(""+pname+"");       }      });   });

which fetches variables via api.php looks this:

    <?php  $db = new pdo('mysql:host=xxxxx;dbname=xxxxx;charset=utf8', 'xxxxx', 'xxxxx');  $partyinput = $_post['paramname'];  $stmt = $db->prepare("select * playr_partyid_db partyid = $partyinput");  $stmt->execute(array($_post['paramname']));  $rows = $stmt->fetchall(pdo::fetch_assoc);  ?>

but problem i've got text input on web page, when user writes "partyid" in , clicks continue want script fetch information row id. it's fetching 1st row.

i've never worked ajax before if you've got time, please explain what's happening too.

thanks in advance.

edit:

here's input, note haven't optimized page in terms of css yet. 

<form style="margin-top:150px;" method="post" action="">               <div class="list-block">                 <ul>                   <li class="item-content" style="background: #fff;margin-bottom: -26px;">                     <div class="item-inner">                       <div class="item-input">                         <input style="text-align:center;padding:0;" type="text" name="partyid" placeholder="ange partyid">                       </div>                     </div>                   </li>                 </ul>               </div>               <div class="list-block">                 <ul>                   <li>                       <input type="submit" name="submit" value="festa p&aring;!" class="login_bttn" style="  background: none;color: white;border: 1px solid white;border-radius: 500px;width: auto;margin-left: auto;margin-right: auto;margin-top: 40px;"></input>                   </li>                 </ul>                 <div class="list-block-labe"></div>               </div>             </form>

first of all, pass parameter, update data: "", 

data: {     paramname: $("#idoffield").val() },

secondly, jay blanchard mentioned, switch pdo

$db = new pdo('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');  $stmt = $db->prepare("select * playr_partyid_db partyid =?");  $stmt->execute(array($_post['paramname']));  $rows = $stmt->fetchall(pdo::fetch_assoc);

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
