Display data in a table by its id after successful AJAX call - php

Question

i have a search input field in my page. currently i am displaying data from the database successfully in a table(id="table_userinfo"). Now i want to add the live search functionality to my table(id="table_userinfo") as well. i am using php codeigniter.
in my user_model i have:
function search_userInfo($keyword)
{
$this->db->like('DeviceName',$keyword);
$this->db->or_like('RegistrationDateTime',$keyword);
$this->db->or_like('LastUpdateDateTime',$keyword);
$this->db->or_like('AppVersion ',$keyword);
$this->db->or_like('iOSVersion',$keyword);
$this->db->or_like('DeviceDID',$keyword);
$this->db->or_like('DeviceToken',$keyword);
$query = $this->db->get('userinfo');
if($query)
{
return $query->result();
}
else
{
return NULL;
}
}
in my login_controller:
function displayDatabase()
{
$data['tableInfo']=$this->user_model->fetchData();
$this->load->view('adminPanel_view',$data);
}
function search()
{
$search=$this->input->post('searchString');
$data['tableInfo']=$this->user_model->search_userInfo($search);
}
in my adminPanel_view page, i have:
<script>
$('#search').keyup(function(){
var input_data = {searchString: $('#search').val() };
//console.log(input_data);
$.ajax({
type:"POST",
url:base_url+'index.php/login_controller/search',
data:input_data,
success:function(data){
if(data.length>0)
{
console.log(data);
}
}
});
});
</script>
<table class="table table-bordered table-hover table-full-width" id="table_userinfo">
<thead>
<tr>
<th>Serial No.</th>
<th class="hidden-xs">Device Name</th>
<th>Device Type</th>
<th>RegistrationDateTime </th>
<th>LastUpdateTime</th>
<th>LastPushNotificationSent</th>
<th>Actions</th>
</tr>
</thead>
<tbody>
<?php //print_r ($tableInfo);exit;?>
<?php $no=0;?>
<?php foreach($tableInfo as $r): ?>
<tr>
<td><?php echo $no ?></td>
<td><?php echo $r->DeviceName ?></td>
<td><?php echo $r->DeviceType ?></td>
<td><?php echo $r->RegistrationDateTime ?></td>
<td><?php echo $r->LastUpdateDateTime ?></td>
<td><?php echo $r->LastPushNotificationSent ?></td>
<td><?php echo "Actions" ?></td>
</tr>
<?php $no+=1;?>
<?php endforeach; ?>
</tbody>
</table>
this is the search bar that i am using in addition to this table
<div id="" class="dataTables_filter">
<label>
<input placeholder="Search" class="form-control input-sm" aria-controls="sample_1" type="text" id="search" name="search_userinfo">
</label>
</div>
how do i display the data that i am getting through the Ajax call and show it in the table(id="search_userinfo).

Answer 1

inside of function search() return it as:
echo json_encode($this->user_model->search_userInfo($search));
and inside of javascript do this
<script>
$('#search').keyup(function(){
var input_data = {searchString: $('#search').val() };
//console.log(input_data);
$.ajax({
type:"POST",
url:base_url+'index.php/login_controller/search',
data:input_data,
dataType: "json",
success:function(data){
$("#table_userinfo").html(" "); //clear everything from table
data.forEach(function(entry) {
$("#table_userinfo").append("<td>"+entry.DeviceName+"</td><td>");
//just add everything here
});
}
});
});
</script>

Your Controller
function search()
{
$search=$this->input->post('searchString');
$data['tableInfo']=$this->user_model->search_userInfo($search);
print_r(json_encode($data['tableInfo']));exit
}
In your ajax add this line
dataType:'json';
Now In Your Success function You will get an json for that data ,You can append like this,
$.each(data, function(i, item) {
alert(item.DeviceName); // append data where you need to append
});​
But Please be sure about amount of data you get in success function, with keyup
