mysql - Getting multi rows in the table even if my database has no value using angular.js and PHP -


i have 1 problem in angular.js code.i have table filled database value. when database has no value , table should display blank in case database empty still table splitting 5 rows has no value.i explaining code below.

subject.html:

<table class="table table-bordered table-striped table-hover" id="datatable">     <colgroup>         <col class="col-md-1 col-sm-1">         <col class="col-md-2 col-sm-2">         <col class="col-md-2 col-sm-2">         <col class="col-md-2 col-sm-2">         <col class="col-md-2 col-sm-2">         <col class="col-md-2 col-sm-2">         <col class="col-md-1 col-sm-1">     </colgroup>     <thead>         <tr>             <th>sl. no</th>             <th>                 <select style="width:100%; border:none; font-weight:bold;">                     <option>course name</option>                 </select>             </th>             <th>semester</th>             <th>subject name</th>             <th>short name</th>             <th>edit</th>         </tr>     </thead>                                            <tbody id="detailsstockid">         <tr ng-repeat="sub in subjectdata" >             <td>{{ $index+1 }}</td>             <td>{{sub.course_name}}</td>             <td>{{sub.semester}}</td>             <td>{{sub.subject_name}}</td>             <td >{{sub.short_name}}</td>             <td>                 <a href=''>                     <input type='button' class='btn btn-xs btn-green' value='edit'>                   </a>             </td>         </tr>        </tbody> </table>

subjectcontroller.js:

var subapp=angular.module('gofastohome'); subapp.controller('subjectcontroller',function($scope,$http){     $http({         method: 'get',         url: "php/subject/readsubjectdata.php",     }).then(function successcallback(response) {         console.log('response',response);         $scope.subjectdata=angular.fromjson(response);     },function errorcallback(response) {         alert("could not fetch data");     }); })

here database has no value.when user refreshing(i.e-subject.html) page table present in html content splitting 5 rows no data 5 serial number coming don't need.check php file below.

readsubjectdata.php:

$connect = mysqli_connect("localhost", "root", "******", "go_fasto"); $result = mysqli_query($connect, "select * db_subject order subject_id desc "); $data = array(); while ($row = mysqli_fetch_assoc($result)) {   $data[] = $row; } print json_encode($data);

my requirement table splitted when database has value.when data database blank should not getting in current code.please me.

try this:

  1. add script ng-show="showtable" table tag become this:

    <table ng-show="showtable" class="table table-bordered table-striped table-hover" id="datatable">

  2. then change controller script below:

    var subapp=angular.module('gofastohome'); subapp.controller('subjectcontroller',function($scope,$http){     $http({         method: 'get',         url: "php/subject/readsubjectdata.php",     }).then(function successcallback(response) {         console.log('response',response);         $scope.subjectdata=angular.fromjson(response);         if($scope.subjectdata.length > 0) //              $scope.showtable = true;      // add these lines         else                              //             $scope.showtable = false;     //      },function errorcallback(response) {         alert("could not fetch data");     }); })
