in file

      <?php          echo json_decode($_post['posttime']);          echo json_decode($_post['postcountry']);          echo var_dump($_post);       ?>

//in ajax call data no need strigyfy data.

<script type="text/javascript">          var country = document.getelementbyid("country");          var time = document.getelementbyid("time");          function showdata() {            $.ajax({              type: "post",              datatype:  "json",              url: "abdullahpass.php",             //async: false,              data: {postcountry: country,posttime: time},              success: function(data) {                 console.log(data);                },              error: function(jqxhr, textstatus, errorthrown) {                 alert('an error occurred... @ console (f12 or                  ctrl+shift+i, console tab) more information!');                 $('#resulte').html('<p>status code: '+jqxhr.status+'</p>                 <p>errorthrown: ' + errorthrown + '</p><p>jqxhr.responsetext:</p>                 <div>'+jqxhr.responsetext + '</div>');                 console.log('jqxhr:');                 console.log(jqxhr);                 console.log('textstatus:');                 console.log(textstatus);                 console.log('errorthrown:');                 console.log(errorthrown);               },            });         }         </script>

i got error states undefined index postcountry not error warning, using isset function can overcome same , $_post['posttime'] , $_post['postcountry'] values. should use json_encode on array only.

    <?php           echo (isset($_post['posttime']) && $_post['posttime']) ? $_post['posttime'] : 'no value posttime';          echo (isset($_post['postcountry']) && $_post['postcountry']) ? $_post['postcountry'] : 'no value postcountry';            //this print total post data type          echo var_dump($_post);       ?>

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
