customer_to_supply()函数更改为以下代码
public function customer_to_supply($id, $time = null, $type = null) {
$this->db->select('*');
$this->db->from('communication');
$this->db->join('supplier_otherdetails', 'supplier_otherdetails.supplierid_fk = communication.supplier_id');
$this->db->join('customer_registration', 'communication.Customer_id=customer_registration.id');
$array = array('communication.product_id' => $id, 'communication.supplier_id' => $this->session->id);
$this->db->where($array);
if($time != '')
$this->db->where('unix_timestamp(msg_sent_time) >', $time, false );
if($type != '')
$this->db->where('From', $type );
$this->db->order_by("msg_sent_time");
$query = $this->db->get();
$results = [];
if ($query->num_rows() > 0) {
$results = $query->result();
}
return $results;
}
并在脚本中添加以下代码
var last_time = $("#last-time").val();
getMessages = function() {
var self = this;
console.log(last_time);
var url = '<?php echo base_url(); ?>index.php/Profile_cntrl/get_message/customer/<?=$_GET['id']?>/'+last_time;
$.getJSON(url, function(data){
console.debug(data);
if(data.status) {
last_time = data.next_time;
$("#last-time").val(data.next_time);
$('#chat_log').append(data.message);
scrollDown();
}
setTimeout(function(){
getMessages();
}, 5000);
});
}
getMessages();
在视图页面中。您必须按照以下方式进行一些更改
$msg_sent_time = '';
$msg_sent_time = $row->msg_sent_time;
<input id="last-time" value="<?=strtotime($msg_sent_time);?>">

对于聊天和类似需求，有Laravel + Echo npm包
见这里： https://laravel.com/docs/5.3/broadcasting#installing-laravel-echo
