This is my first post on this site, and while I have gone through the 2 min. tour please guide me in the right direction if this question seems misplaced or not in line with the site's rules.
I have created/modified a PHP script (below), that puts a MySQL table in a JSON format. I'm working with 700,000+ rows so I thought my best bet was to use pagination.
<?php
require('connection.php');
header('Content-Type: application/json');
ini_set("max_execution_time", "-1");
ini_set("memory_limit", "-1");
ignore_user_abort(true);
set_time_limit(0);
// PortalActivity Table - JSON Creation
$limit = $_POST['limit']; //the pagesize
$start = $_POST['start']; //Offset
$dir = $_POST['dir']; // DESC or ASC
$sort = $_POST['sort'];// the column
switch ($sort) {
case "CallerPhoneNum": $orderby = "CallerPhoneNum"; break;
case "Carrier": $orderby = "Carrier"; break;
case "TotalLookups": $orderby = "TotalLookups"; break;
case "TotalBlocks": $orderby = "TotalBlocks"; break;
case "TotalComplaints": $orderby = "TotalComplaints"; break;
case "ActivityRanking": $orderby = "ActivityRanking"; break;
case "CallerType": $orderby = "CallerType"; break;
}
$sql = "SELECT COUNT(*) AS count FROM portal.PortalActivity";
$result = $conn->query($sql);
$row = $result->fetch(PDO::FETCH_ASSOC);
$count = $row['count'];
$query = "SELECT * FROM portal.PortalActivity ORDER BY $orderby $dir LIMIT $start, $limit";
$result = $conn->query($query);
while ($row = $result->fetch(PDO::FETCH_ASSOC)) {
$PortalActivity[] = array(
'CallerPhoneNum' => $row['CallerPhoneNum'],
'Carrier' => $row['Carrier'],
'TotalLookups' => $row['TotalLookups'],
'TotalBlocks' => $row['TotalBlocks'],
'TotalComplaints' => $row['TotalComplaints'],
'ActivityRanking' => $row['ActivityRanking'],
'CallerType' => $row['CallerType']
);
}
$myData = array('PortalActivity' => $PortalActivity, 'totalCount' => $count);
echo json_encode($myData);
?>
The code gives me the data in all the rows as well as a Total Count of the rows.
I have a bootstrap framework that uses AngularJS. I would like to put the data in a table using pagination. So, when ever a user clicks "next" or clicks to a new page, the server would only load the necessary records per page (10, 25, 50, or 100).
I know that I am needing to: 1.) Create the paging in my controller 2.) Get the data from my controller to my php file so it can correctly receive the right limits and offsets. 3.) Display this in my view
I am new to these languages and I have found myself in a time crunch to get this demo out. How can I get these files working together (PHP, JS, and HTML) to correctly display the paging I need?
This is my original controller that is just displaying the data in a filtered view. As shown below, I'm using $http.get to get the data. This controller works, but I'm needing to take it a step further with the paging:
app.controller('counterCtrl', function($scope, $http, $filter, filterFilter) {
$scope.Unknown = 'UK';
$scope.NonProfit = 'NP';
$scope.Political = 'PL';
$scope.Prison = 'PR';
$scope.getCount = function(strCat) {
return filterFilter( $scope.items, {CallerType:strCat}).length;
}
$http.get(".php")
.success(function (data) {
$scope.items = data.PortalActivity;
});
})
This is part of the view I've created with the working controller:
<section id="main-content" class="animated fadeInRight">
<div class="row">
<div class="col-md-12">
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title">Unknown</h3>
</div>
<div class="panel-body">
<table id="example" class="table table-striped table-bordered" datatable="" cellspacing="0" width="100%">
<thead>
<tr>
<th>Caller Number</th>
<th>Total Lookups</th>
<th>Total Blocks</th>
<th>Total Complaints</th>
<th>Activity Percentage</th>

- 1 This is tangential to your question, but your PHP is seriously vulnerable to SQL injection attacks. You should strongly consider establishing your database connection using the PDO API and making parameterized queries via prepared statements. – Mr. DOS Commented Jul 8, 2015 at 19:15
- Thank you for your ment. I've made an attempt at using PDO. The example that I was reading from used mysqli. I'm still learning how to convert this to PDO. I will review your link about prepared statements and update accordingly. – ChaiBunnii Commented Jul 8, 2015 at 19:44

Reset to default 1For anyone that has e across this question, I've found the answer to this problem. Do note, as Mr. DOS has mentioned in a previous ment, this is vulnerable to SQL injection and I WILL modify the PHP code later. But for right now this gives me what I need and maybe it will help others along the way.
There were a few changes in my PHP that I needed to do:
<?php
require('connection.php');
header('Content-Type: application/json');
// NetworkActivity Table - JSON File Creation
$pagenum = $_GET['page'];
$pagesize = $_GET['size'];
$offset = ($pagenum - 1) * $pagesize;
$search = $_GET['search'];
if ($search != "") {
$where = "WHERE Carrier LIKE '%" . $search . "%'";
} else {
$where = "";
}
$sql = "SELECT COUNT(*) AS count FROM PortalActivity $where";
$result = $conn->query($sql);
$row = $result->fetch(PDO::FETCH_ASSOC);
$count = $row['count'];
$query = "SELECT * FROM portal.PortalActivity $where ORDER BY Carrier, CallerPhoneNum LIMIT $offset, $pagesize";
$result = $conn->query($query);
while ($row = $result->fetch(PDO::FETCH_ASSOC)) {
$PortalActivity[] = array(
'CallerPhoneNum' => $row['CallerPhoneNum'],
'Carrier' => $row['Carrier'],
'TotalLookups' => $row['TotalLookups'],
'TotalBlocks' => $row['TotalBlocks'],
'TotalComplaints' => $row['TotalComplaints'],
'ActivityRanking' => $row['ActivityRanking'],
'CallerType' => $row['CallerType']
);
}
$myData = array('PortalActivity' => $PortalActivity, 'totalCount' => $count);
echo json_encode($myData);
?>
As for as the controller, we duplicated the paging and got the PHP $_GET from the $http.get in the URL with page, size, and search.
// Portal Activity Table Control
app.controller('activityTableCtrl', function($scope, $http) {
$scope.currentPage = 1;
$scope.totalItems = 0;
$scope.pageSize = 10;
$scope.searchText = '';
getData();
function getData() {
$http.get('http://xx.xxx.xx.xx/php/jsoncreatePA.php?page=' + $scope.currentPage + '&size=' + $scope.pageSize + '&search=' + $scope.searchText)
.success(function(data) {
$scope.activity = [];
$scope.totalItems = data.totalCount;
$scope.startItem = ($scope.currentPage - 1) * $scope.pageSize + 1;
$scope.endItem = $scope.currentPage * $scope.pageSize;
if ($scope.endItem > $scope.totalCount) {$scope.endItem = $scope.totalCount;}
angular.forEach(data.PortalActivity, function(temp){
$scope.activity.push(temp);
});
});
}
$scope.pageChanged = function() {
getData();
}
$scope.pageSizeChanged = function() {
$scope.currentPage = 1;
getData();
}
$scope.searchTextChanged = function() {
$scope.currentPage = 1;
getData();
}
})
Finally, we changed up the view to acmodate the paging controls.

<div class="row">
<div class="col-md-12" ng-controller="activityTableCtrl">
<div class="panel panel-default">

</tbody>

You can easily paging using client side cause if use server side every page number button click page refresh and and get data form database. It is now looking quality full. So solve this quality work use jQuery data table.
