How can I print "not found" when the code output is empty? - javascript

I mixed an "ajax select" and "while scrolling load data" script, and this is working, but I don't know how to print "not found data" in div.status when the output variable (on animals.php) is empty.

Why is this AJAX call not working in IE 11?

I have a notifications system on my site, that utilizes AJAX to update in real-time. The problem is that it works on every browser except IE 11. After looking around I noticed some people advising to use cache:false in the call. However, this makes the code non-functional across all browsers. Anyone know what the solution is?
JAVASCRIPT:
<script>
$(document).ready(function(){
$('.notif_count').html('0');
function load_unseen_notification(view = '')
{
$.ajax({
url:"notif_follow.php",
method:"POST",
data:{view:view},
dataType:"json",
success:function(data)
{
$('.notif_follow').html(data.notification);
if(data.notif_count > 0)
{
$('.notif_count').html(data.notif_count);
}
}
});
}
load_unseen_notification();
$(document).on('click', '.notif', function(){
$('.notif_count').html('0');
load_unseen_notification('yes');
});
setInterval(function(){
load_unseen_notification();;
}, 5000);
});
</script>
PHP:
<?php
session_start();
require_once 'class.channel.php';
$user_notif = new USER();
$user_id = $_SESSION['userID'];
if(isset($_POST["view"]))
{
if($_POST["view"] != '')
{
$stmt = $user_notif->runQuery("UPDATE notif_follow SET status = 1 WHERE receive_id = ?");
$stmt->bindValue(1,$user_id);
$stmt->execute();
}
$stmt = $user_notif->runQuery("SELECT * FROM tbl_users WHERE userID=:uid");
$stmt->execute(array(":uid"=>$user_id));
$row = $stmt->fetch(PDO::FETCH_ASSOC);
$stmt = $user_notif->runQuery("SELECT * FROM notif_follow WHERE receive_id= ? ORDER BY id DESC LIMIT 5");
$stmt->bindValue(1,$user_id);
$stmt->execute();
$notifs = $stmt->fetchAll(PDO::FETCH_ASSOC);
$notification = '';
if(count($notifs) > 0)
{
foreach($notifs as $notif)
{
$send_id = $notif['send_id'];
$query2 = $user_notif->runQuery("SELECT * FROM following WHERE user1_id=:uid1 AND user2_id=:uid2");
$query2->execute(array(":uid1"=>$user_id,":uid2"=>$send_id));

AngularJS delay loading data from MySQL database

I'm using angular in a simple application like:
app.js
app = angular.module('app', []);
app.controller("NavCtrl",function($scope,$http){
var serviceBase = 'v1/';
$http.get(serviceBase + 'orderoverview/58').then(function (results) {
$scope.categories = results.data;
$scope.getTotal = function(){
var total = 0;
for(var i = 0; i < $scope.categories.length; i++){
var categories = $scope.categories[i];
total += (categories.productPrice * categories.orderdetailAantal);
if(categories.extra1 != "")
{
total += categories.extrasPrice;
}
}
return total;
}
});
});

And this works but every time I load the page there is a delay of almost 3 seconds to get the data from the db and show it in my html page...
When I surf directly to the API, I built using PHP, the required data is shown instantly...
How is this possible and how can I speed up this proces?

Your page doesn't conatains any form tag, so simple use
<button class=submit_btn" id="zsubmit_btn">Dodaj</button> instead of input type = submit
This will Work!!!!

autocomplete search form with multiple input php mysql

Hi Guys I have this search from that takes a search term matches it with a table.field and in php it searches all matching data.
I want to add autocomplete to it, can anyone PLEASE assist?
Here is the HTML FORM
<form action="'.$_SERVER['REQUEST_URI'].'" method="post">
<input type="text" id="searchThis" name="searchThis" placeholder="search" value="" size="14" />
<select name="searchItems" id="searchItems">
<optgroup value="Vehicles" label="Vehicles">Vehicles
<option value="vehicles.Make">Make</option>
<option value="vehicles.model">Model</option>
<option value="vehicles.RegNumber">Registration Number</option>
<option value="vehicles.licenseExpireDate">License Expire Date</option>
</optgroup>
<optgroup value="Owners" label="Owners">Clients
<option value="owners.OwnerName" label="" >Name</option>
<option value="owners.mobile">Mobile Number</option>
</optgroup>
</select>
<input type="submit" id="doSearch" name="Search" value="Search" />
</form>
<ul id="result">
</ul>
There is the JS
<script src="js/jquery-1.8.0.min.js" type="text/javascript"></script>
<script type="text/javascript">
var $j = jQuery.noConflict();
(function($j){
$j(document).ready(function (){
$j("#searchThis").keyup(function()
{
var searchThis = $j('#searchThis').val();
var searchItems = $j('#searchItems').val();
var dataString = {'searchThis': searchThis,'searchItems':searchItems};
if(searchThis!='')
{
$j.ajax({
type: "POST",
url: "doAutocomplete_search.php",
data: dataString,
dataType: "html",
cache: false,
success: function(data)
{
$j("#result").html(data).show();
}
});
}return false;
});
$j("#result").live("click",function(e){
var clicked = $j(e.target);
var name = clicked.find('.name').html();
var decoded = $j("<div/>").html(name).text();
$j('#searchThis').val(decoded);
});
$j(document).live("click", function(e) {
var clicked = $j(e.target);
if (! clicked.hasClass("search")){
$j("#result").fadeOut();
}
});
$j('#searchid').click(function(){
$j("#result").fadeIn();
});
});
})($j);
And the PHP
function implement($cxn,$searchThis, $field) {
$show = "";
//Item to be searched
$srchThis = strip_tags(trim($searchThis));
//[0]= table , [1]=field to search
$srchStack = explode('.',$field);
$gtData = "SELECT * FROM ".$srchStack[0]." WHERE ".$srchStack[1]." like '%|{$srchThis}|%'";
//or die(mysqli_error($cxn))
if($selectc = mysqli_query($cxn,"SELECT * FROM {$srchStack[0]} WHERE {$srchStack[1]} LIKE '{$srchThis}%' OR {$srchStack[1]} LIKE '%{$srchThis}%'")) {
$srchData = array();
$rows = mysqli_fetch_row($selectc);
echo $rows;
//if() {, MYSQL_ASSOC
//echo var_dump($srchData);
$show .= '
<table style="border:2px solid #0000">';
//foreach($srchData as $fields=>$data) {
for($s=0; $s < $rows && $srchData = mysqli_fetch_assoc($selectc);$s++) {
if($srchStack[0] == 'vehicles' && $fields == 'RegNumber') {
$dataItem = $data;
$editTbl = 'Vehicles';
$link = 'href="index.php?list=vehicles&&tbl='.$srchStack[0].'&&item='.$dataItem.'"';
} elseif($srchStack[0] == 'vehicles' && $fields == 'Make') {
$dataItem = $data;
$editTbl = 'vehicles';
$link = 'href="index.php?list=vehicles&&tbl='.$srchStack[0].'&&item='.$dataItem.'"';
}
$show .= '<tr><td><a '.$link.'>'.$data.'</a></td></tr>
';
}
$show .= '</table>';
return $show;
} else {
$show .= "There are no entries in the database...<br>".mysqli_error($cxn);
return $show;
}
//}
}
echo implement($cxn, $_POST['searchThis'], $_POST['searchItems']);
$cxn->close();
Hi Guys so i had to do some refactoring, realized it was more the PHP MySQL code.
Here is the refactored PHP code
//Item to be searched
$srchThis = strip_tags(trim($searchThis));
//[0]= table , [1]=field to search
$srchStack = explode('.',$field);
$gtData = "SELECT * FROM ".$srchStack[0]." WHERE ".$srchStack[1]." like '%|{$srchThis}|%'";
//or die(mysqli_error($cxn))
if($selectc = mysqli_query($cxn,"SELECT * FROM {$srchStack[0]} WHERE {$srchStack[1]} LIKE '{$srchThis}%' OR {$srchStack[1]} LIKE '%{$srchThis}%'")) {
//$srchData = array();
$rows = mysqli_num_rows(#$selectc) or die(mysqli_error($cxn).'<br>No Rows returned...');
if($rows > 0) {//, MYSQL_ASSOC
//$link = ''; $l_c = 0;
$show .= '<table style="border:2px solid #0000">';
for($c = NULL;$c != $rows && $srchData = mysqli_fetch_assoc($selectc); $c++) {
foreach($srchData as $fields=>$data) {
if($fields == $srchStack[1]) {
$dataItem = $data;
$editTbl = $srchStack[0];
$show .= '<tr><td>'.$dataItem.'</td></tr>';//$a_json_row($dataItem);
//$show .= $link[$c];$link[$c]
}
}
}
$show .= '</table>';
return $show;
} else {
$show .= "There are no entries in the database...<br>".mysqli_error($cxn);
return $show;
}
Of-course the JS code still needs some more work but this greatly improved the results...
Hope this help someone...
