mysql - Is it possible to send POST data to another php in ajax? -

i've built search form , i've tried send $_post data php in ajax not work.

and want know, possible if want send $_post data url:"searchby.php" in ajax?

search.php :

<form action="<?php echo htmlspecialchars($_server["php_self"]);?>" method="post" id="searchterm">    <input type="text" name="search" id="search" autocomplete="off">    <button type="loading" class="btn btn-primary">add</button> </form>  <script type="text/javascript">     var ajax_arry=[];     var ajax_index =0;     var sctp = 100;      $(function(){         $('#loading').show();         $.ajax({             url:"searchby.php",             type:"post",             data:"actionfunction=showdata&page=1",             cache: false,             success: function(response){                 $('#loading').hide();                 $('#demoajax').html(response);             }         });          $(window).scroll(function(){              var height = $('#demoajax').height();             var scroll_top = $(this).scrolltop();             if(ajax_arry.length>0){                 $('#loading').hide();                 for(var i=0;i<ajax_arry.length;i++){                     ajax_arry[i].abort();                 }             }             var page = $('#demoajax').find('.nextpage').val();             var isload = $('#demoajax').find('.isload').val();             var searchterm = "<?php echo $x; ?>";              if ((($(window).scrolltop()+document.body.clientheight)==$(window).height()) && isload=='true'){                 $('#loading').show();                 var ajaxreq = $.ajax({                     url:"searchby.php",                     type:"post",                     data:"actionfunction=showdata&page="+page,                     cache: false,                     success: function(response){                         $('#demoajax').find('.nextpage').remove();                         $('#demoajax').find('.isload').remove();                         $('#loading').hide();                         $('#demoajax').append(response);                     }                 });                 ajax_arry[ajax_index++]= ajaxreq;             }             return false;             if($(window).scrolltop() == $(window).height()) {              alert("bottom!");          }      }); });  </script> 

and searchby.php should this.

searchby.php :

$searchstring = $_post['search']; $sql = "select * product p_name '%$searchstring %'"; 

you need send search value in ajax param as:

var searchval = $("#search").val(); // value of search box $.ajax({     url:"searchby.php",     type:"post",     data:"search="+searchval+"&actionfunction=showdata&page=1",     cache: false,     success: function(response){         $('#loading').hide();         $('#demoajax').html(response);     } });

update 1:

send ajax request when form submit, can follow example:

$(".btn").click(function(){  var searchval = $("#search").val(); // value of search box $.ajax({     url:"searchby.php",     type:"post",     data:"search="+searchval+"&actionfunction=showdata&page=1",     cache: false,     success: function(response){         $('#loading').hide();         $('#demoajax').html(response);     } });  }); 

in php (searchby.php) debug getting in $_post:

echo "<pre>"; print_r($_post);
