I am trying to set up a way for two tables on my page to updated automatically or if correct me if I am wrong "Asynchronously". I need second to second updates as well. I am also using CodeIgnighter MVC framework, and as for my tables I am using DataTables. My Jquery goes as follows :
<script>
function updatewaiting(){
$('.display').load('https://www.finaidtest.com/index.php/studentqueue_controller/data');
}
setInterval( "updatewaiting()", 1000 );
</script>
My tables are as follows :
<table id='waiting' class='display'>
<thead>
<tr>
<th>ID</th>
<th>A Number</th>
<th>First Name</th>
<th>Last Name</th>
<th>Time Waiting</th>
<th>Reason for visit</th>
<th>Comments</th>
<th>Aid Year</th>
<th>Staff Comments</th>
<th>Options</th>
</tr>
</thead>
<tbody>
<?php
$options = array("" => "", 'start' => 'Start Session', 'stop' => 'Student Not Present', 'abandon' => 'End Session',);
foreach ($waiting as $row) {
?>
<tr>
<td><?php echo htmlspecialchars($row['id'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo anchor('studentqueue_controller/history/' . urlencode($row['anum']) . '', htmlspecialchars($row['anum'], ENT_QUOTES, 'UTF-8'), 'target="_blank"'); ?></td>
<td><?php echo htmlspecialchars($row['first'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlspecialchars($row['last'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlspecialchars($row['SECOND'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlspecialchars($row['reason'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlspecialchars($row['studentcomments'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlspecialchars($row['aidyear'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlspecialchars($row['counselorcomments'], ENT_QUOTES, 'UTF-8'); ?></td>
<td>
<?php echo form_open('studentqueue_controller/counselorscreen/' . urlencode($row['id']) . ''); ?>
<?php echo form_dropdown('options', $options, ""); ?>
<?php echo form_submit('submit', 'Submit'); ?>
<?php echo form_close(); ?>
</td>
</tr>
<?php }
?>
</tbody>
</table>
<table id='beingseen' class='display'>
<thead>
<tr>
<th>ID</th>
<th>A Number</th>
<th>First Name</th>
<th>Last Name</th>
<th>Sign In Time</th>
<th>Staff Member</th>
<th>Start Time</th>
<th>Options</th>
</tr>
</thead>
<tbody>
<?php $options1 = array("" => "", 'continue' => 'Continue Session', 'terminate' => 'Terminate Session',);
foreach ($beingseen as $row1) {
?>
<tr>
<td><?php echo htmlspecialchars($row1['id'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlspecialchars($row1['anum'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlspecialchars($row1['first'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlspecialchars($row1['last'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlspecialchars($row1['signintime'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlspecialchars($row1['fname'], ENT_QUOTES, 'UTF-8'); ?></td>
<td><?php echo htmlspecialchars($row1['starttime'], ENT_QUOTES, 'UTF-8'); ?></td>
<td>
<?php echo form_open('studentqueue_controller/counselorscreen/' . urlencode($row1['id']) . ''); ?>
<?php echo form_dropdown('options', $options1, ""); ?>
<?php echo form_submit('submit', 'Submit'); ?>
<?php echo form_close(); ?>
</td>
</td>
</tr>
<?php } ?>

The Jquery function is calling on my data() method in my controller and all that does is query the database :
function data(){
$this->load->model('queue_model');
$data['waiting'] = $this->queue_model->waiting();
$data['beingseen'] = $this->queue_model->beingseen();
}
I am quite confused as to why when I look into my network tab I see the ajax calls, but I do not see a response in the network tab.
Just an up date :
Array ( [waiting] => Array ( [0] => Array ( [id] => 176 [0] => 176 [anum] => A00163047 [1] => A00163047 [first] => rix [2] => rix [last] => aja [3] => aja [SECOND] => 62:47:39 [4] => 62:47:39 [reason] => Award Status [5] => Award Status [studentcomments] => [6] => [aidyear] => 13-14 [7] => 13-14 [counselorcomments] => [8] => ) [1] => Array ( [id] => 179 [0] => 179 [anum] => A00163047 [1] => A00163047 [first] => rix [2] => rix [last] => aja [3] => aja [SECOND] => 00:22:29 [4] => 00:22:29 [reason] => Award Status [5] => Award Status [studentcomments] => [6] => [aidyear] => 13-14 [7] => 13-14 [counselorcomments] => [8] => ) [2] => Array ( [id] => 178 [0] => 178 [anum] => A12345678 [1] => A12345678 [first] => ririri [2] => ririri [last] => ririir [3] => ririir [SECOND] => 00:24:21 [4] => 00:24:21 [reason] => Award Status [5] => Award Status [studentcomments] => [6] => [aidyear] => 13-14 [7] => 13-14 [counselorcomments] => [8] => ) [3] => Array ( [id] => 177 [0] => 177 [anum] => A99999999 [1] => A99999999 [first] => rux [2] => rux [last] => ajaj [3] => ajaj [SECOND] => 00:29:20 [4] => 00:29:20 [reason] => Award Status [5] => Award Status [studentcomments] => [6] => [aidyear] => 13-14 [7] => 13-14 [counselorcomments] => [8] => ) ) [beingseen] => )
My data function in fact is returning data to the controller. I just did a print_r on my data. however that array of returned data is being placed into the table itself,
In your case you should load a view and print it in javascript using load()
, so use:
function data(){
$this->load->model('queue_model');
$data['waiting'] = $this->queue_model->waiting();
$data['beingseen'] = $this->queue_model->beingseen();
echo $this->load->view('myview',$data,true);
}
and your view will be outputted where you are specifiying with $(_element).load();
just to be sure you understood the load() jquery method:
when you do $('div#element').load('myfile.php');
you are outputtting the returning data from myfile.php
into the <div id="element"></div> html
element
