javascript - Passing values to PHP with JQuery AJAX not working, array confusion -


i've searching in web 1 week , found 15 questions asking same thing me, don't see find correct solution.
problem simple. have html table in 1 page , want pass table thru ajax(jquery) , execute php script, don't see i'm doing wrong, here's code, can post more if needed.

ajax now(the real problem here array definition?):

$(function(){   $('#nice_button').on('click', function(e){     // using core $.ajax() method     $.ajax({         // url request         url: "ajax_insert_suba_def.php",          var data2 = [{             value1 :  [1,2,3,4,5],             value2 :  [5,4,3,2,1]         }];          // data send (will converted query string)         data: { 'data': data2 },         // whether post or request         type: "post",         // type of data expect         // datatype : "json",         // code run regardless of success or failure         complete: function( xhr, status ) {             alert( "the request complete!" );         }     });   }); });

with html:

<form method="post" name="my_form">     <button id="nice_button" type="button" name="btn_go" class="btn btn-success btn-lg"> insert db</button> </form>

with basic php: (the functions ok ... need know how 'get' values)

<?php      header("content-type: application/json");      require "includes/functions.php" ;      $my_sqli = connect_to_mysql();      $data = $_post['data'];       $val_1 = $data["value1"][0];     $val_2 = $data["value2"][0];      $query = "insert test_json (test_text) values('" . $val_1 . "'); ";      $result = $my_sqli->query($query);      $my_sqli->close();      return "ok";  ?>

by error i'm getting this:

syntaxerror: missing : after property id

(in var data2= ... line)

thanks help!

syntaxerror: missing : after property id

you have take data2 outside of ajax request, this:

$(function(){     $('#nice_button').on('click', function(e){          var data2 =          [             {                 value1 :  [1,2,3,4,5],                 value2 :  [5,4,3,2,1]             }         ];           // using core $.ajax() method         $.ajax({              // url request             url: "ajax_insert_suba_def.php",              // data send (will converted query string)             data: { data: data2 },              // whether post or request             type: "post",              // type of data expect             // datatype : "json",              // code run regardless of success or failure             complete: function( xhr, status ) {                 alert( "the request complete!" );             }         });     }); });

i need know how 'get' values

this how can individual values:

<?php      // code      $data = $_post['data'];      $val_1 = $data[0]['value1'][0];     $val_2 = $data[0]['value1'][1];      // on      $val_5 = $data[0]['value1'][4];     $val_6 = $data[0]['value2'][0];     $val_7 = $data[0]['value2'][1];      // on      $val_10 = $data[0]['value2'][4];      // code  ?>

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
