MySQL Search Box with AJAX

I got a small problem.
I want to look up the name by entering the website. Now, all records are displayed. What I want is that he shows it after something has been entered in the input. I don't want him to show everything immediately.
Here some code to know how it looks like.
FETCH.PHP
Get everything from database
if(isset($_POST["query"]))
{
$search = mysqli_real_escape_string($connect, $_POST["query"]);
$query = "
SELECT * FROM tbl_customer
WHERE website LIKE '%".$search."%'
OR naam LIKE '%".$search."%'
";
}
else
{
$query = "
SELECT * FROM test ORDER BY id
";
}
$result = mysqli_query($connect, $query);
if(mysqli_num_rows($result) > 0)
{
$output .= '
<div class="table-responsive">
<table class="table table bordered">
<tr>
<th>Website</th>
<th>Naam</th>
</tr>
';
while($row = mysqli_fetch_array($result))
{
$output .= '
<tr>
<td>'.$row["website"].'</td>
<td>'.$row["naam"].'</td>
</tr>
';
}
echo $output;
}
INDEX.PHP
<div class="container">
<br />
<h2 align="center">Ajax Live Data Search using Jquery PHP MySql</h2><br />
<div class="form-group">
<div class="input-group">
<span class="input-group-addon">Search</span>
<input type="text" name="search_text" id="search_text" placeholder="Zoek door website" class="form-control" />
</div>
</div>
<br />
<div id="result"></div>
<script>
$(document).ready(function(){
load_data();
function load_data(query)
{
$.ajax({
url:"fetch.php",
method:"POST",
data:{query:query},
success:function(data)
{
$('#result').html(data);
}
});
}
$('#search_text').keyup(function(){
var search = $(this).val();
if(search != '')
{
load_data(search);
}
else
{
load_data();
}
});
});
</script>

why do u call function load_data(); on load.
this might be the issue
also remove it from else condition

PHP AJAX Filter Issues

I am trying to make a filter for a website for cars. I would like to be able to filter by exterior color. I use exterior to represent my color in the database. My UL puts all color from the database into the box and makes each one a induvial check box. Then I have my page that list of all cars through a SELECT * Statement and then I fetch my results through individual echo statements that are wrap and a div. I Do not want to display my exterior colors name next to each car on this page since I am designing a mobile version and trying to keep it clean. However I have tried to list them as induvial tags and I still get send to a blank page.
<ul class="list-group">
<?php
$sql = "SELECT DISTINCT exterior FROM newcars ORDER BY exterior";
$result = $conn->query($sql);
while($row=$result->fetch_assoc()) {
?>
<li class="list-group-item">
<div class="form-check">
<label class="form-check-label">
<input type="checkbox" class="form-check-input product_check" name="" value="<?= $row['exterior']; ?>" id="exterior"><?= $row['exterior']; ?>
</label>
</div>
</li>
<?php
}
?>
</ul>
<div id="test">
<?php
$sql = "SELECT * FROM newcars";
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
while ($row = mysqli_fetch_assoc($result)) {
echo ("<a href='newcarindex.php?id={$row['id']}'><div class='car'>");
echo '
<tr>
<td>
<img src="data:image\jpeg;base64,'.base64_encode($row['photo']).'"/>
</td>
</tr>
';
echo "<h2 class=car-name>";
echo $row['name'];
echo "</h2>";
echo "<span class=stock>STOCK#";
echo $row['stock'];
echo "</span>";
echo "<h3 class=car-msrp>";
echo $row['msrp'];
echo "</h3>";
echo "</div></a>";
}
} else {
echo "There are no matching results!";
}
?>
</div>
this then leads into my ajax script
<script type="text/javascript">
$(document).ready(function(){
$(".product_check").click(function(){
$("#loader").show();
var action = 'data';
var class = get_filter_text('class');
var body = get_filter_text('body');
var exterior = get_filter_text('exterior');
$.ajax({
url:'action.php',
method:'POST',
data:{action:action,class:class,body:body,exterior:exterior},
success:function(response){
$("#test").html(response);
$("loader").hide();
}
});
});
function get_filter_text(text_id){
var filterData = [];
$('#'+text_id+':checked').each(function(){
filterData.push($(this).val());
});
return filterData;
}
});
</script>
and Finally use a action.php page to connect to my database and filter the results
include 'dbh.php';
if(isset($_POST['action'])) {
$sql = "SELECT * FROM newcars WHERE class !=''";
if(isset($_POST['exterior'])) {
$exterior = implode("','", $_POST['exterior']);
$sql .="AND exterior IN('".$exterior."')";
}
$result = $conn->query($sql);
$output='';
if($result->num_rows>0){
while($row=$result->fetch_assoc()){
$photo = base64_encode($row['photo']);
$output .= "<a href='newcarindex.php?id={$row['id']}'>
<div class='car'>
<tr>
<td>
<img src='data:image\jpeg;base64,{$photo}'/>
</td>
</tr>
<h2 class='car-name'>{$row['name']}</h2>
<span class='stock'>STOCK#{$row['stock']}</span>
<h3 class='car-msrp'>{$row['msrp']}</h3>
</div></a>";
}
echo $output;
}
} else {
echo "There are no comments!";
}
}
?>
The Problem I have is every time i click on a color to filter by my page comes up blank showing no results or errors. What am I doing wrong?

just looking at the action.php, upon a successful query, I don't see $output being echoed. Is this the complete code for the action.php?
include 'dbh.php';
if(isset($_POST['action'])) {
$sql = "SELECT * FROM newcars WHERE class !=''";
if(isset($_POST['exterior'])) {
$exterior = implode("','", $_POST['exterior']);
$sql .="AND exterior IN('".$exterior."')";
}
$result = $conn->query($sql);
$output='';
if($result->num_rows>0){
while($row=$result->fetch_assoc()) {
$photo = base64_encode($row['photo']);
$output .= "<a href='newcarindex.php?id={$row['id']}'>
<div class='car'>
<tr>
<td>
<img src='data:image\jpeg;base64,{$photo}'/>
</td>
</tr>
<h2 class='car-name'>{$row['name']}</h2>
<span class='stock'>STOCK#{$row['stock']}</span>
<h3 class='car-msrp'>{$row['msrp']}</h3>
</div></a>";
}
echo $output;
} else {
echo "There are no comments!";
}
}
?>
```

Excecuting php when clicking a button

So I've made a database where people can upload pictures to. The pictures are linked to a place which is linked to a category.
I'm trying to create a gallery page that displays all the images, and then the categories available. When you click on a category it's meant to show all the pictures for that category.
I've got my categories in my database as well, which I'm using php to echo out:
<?php
include('includes/connectdb.php');
/* Selects id and name from the table 'category' */
$query = "SELECT id, name FROM category";
$result_category = mysqli_query($dbc,$query);
?>
<h1>Category</h1>
<!-- iterate through the WHILE LOOP -->
<?php while($row = mysqli_fetch_array($result_category)): ?>
<!-- Echo out values {id} and {name} -->
<button name="category[]" value=" <?php echo $row['id']; ?> "><?php echo $row['name'] . '<br />'; ?></button>
<?php endwhile; ?>
When a button is clicked I need it to run this php:
<?php
if(isset($_POST['category[]'])){
displayimage();
function displayimage()
{
$con=mysql_connect("localhost","root","");
mysql_select_db("ssdb",$con);
$qry="SELECT pictures.name, pictures.image, pictures.place_id
FROM pictures
INNER JOIN sted
ON pictures.place_id = sted.id
INNER JOIN placecategory
ON sted.id = placecategory.place_id
INNER JOIN category
ON placecategory.category_id = category.id
WHERE placecategory.category_id = $row['id']";
$result=mysql_query($qry,$con);
while($row = mysql_fetch_array($result))
{
//var_dump($row);
echo '<img height="300" width="300" src="data:image;base64,'.$row["image"].' "> ';
echo '<p style="display:inline-block">'.$row["name"].' </p> ';
}
mysql_close($con);
}
}
?>
I found out that it should be possible with ajax, so I added the following to my ajax.php file:
<?php
if (isset($_POST['action'])) {
switch ($_POST['action']) {
case 'category':
category();
break;
}
}
function category() {
displayimage();
function displayimage()
{
$con=mysql_connect("localhost","root","");
mysql_select_db("ssdb",$con);
$qry="SELECT pictures.name, pictures.image, pictures.place_id
FROM pictures
INNER JOIN sted
ON pictures.place_id = sted.id
INNER JOIN placecategory
ON sted.id = placecategory.place_id
INNER JOIN category
ON placecategory.category_id = category.id
WHERE placecategory.category_id = $row['id']";
$result=mysql_query($qry,$con);
while($row = mysql_fetch_array($result))
{
//var_dump($row);
echo '<img height="300" width="300" src="data:image;base64,'.$row["image"].' "> ';
echo '<p style="display:inline-block">'.$row["name"].' </p> ';
}
mysql_close($con);
}
exit;
}
?>
And this to my gallery.php file where I'm displaying the pictures and categories.
<script>
$(document).ready(function(){
$('.button').click(function(){
var clickBtnValue = $(this).val();
var ajaxurl = 'ajax.php',
data = {'action': clickBtnValue};
$.post(ajaxurl, data, function (response) {
// Response div goes here.
alert("action performed successfully");
});
});
});
</script>
And lastly I changed my button to be
<?php while($row = mysqli_fetch_array($result_category)): ?>
<!-- Echo out values {id} and {name} -->
<input type="submit" class="button" name="category[]" value=" <?php echo $row['id']; ?> "><?php echo $row['name'] . '<br />'; ?>
<?php endwhile; ?>
I'm linking to the jquery library and I've tested the SQL statement that I need to run, and it works when I specify what the placecategory.category_id is.

While loop gets killed when refreshing div

I have this JavaScript code refreshing my watcher.php file every 5 seconds and that works great. The first page load is fine but after the 5 seconds and so on the while loop gets killed. Any reason?
index.php file
<script type="text/javascript">
var auto_refresh = setInterval(function(){
$('.view').load('watcher.php');
}, 5000); // refresh div time
</script>
<body>
<div class="view">
<?php include 'watcher.php'; ?>
</div>
</body>
...
watcher.php file
include 'config.php';
$sql = "SELECT id, name, available, will_return, status FROM check_in_out";
$result = $conn->query($sql);
echo '<div style="margin-top:35px;"><center>';
echo '<table class="pure-table">
<thead>
<tr>
<th>Name</th>
<th>Available</th>
<th>Status/Comments</th>
<th>I\'ll Return At:</th>
<th>Returned</th>
</thead>
</tr>
';
if ($result->num_rows > 0) {
$i = 1;
// output data of each row
while ($row = $result->fetch_assoc()) {
echo '<tr>';
echo '<td><img style="vertical-align:middle" src="imgs/card.jpg"> <a class="various" href="#'.$i.'"/>'.$row["name"];'</a></td>';
echo "<td>";
if ($row['available'] == 1) {
echo "<img src='imgs/available.gif'/>";
echo "Online";
} else {
echo "<img src='imgs/not-available.gif'/>";
echo "<span style='vertical-align:middle'>Away</span>";
};
echo "</td>";
echo '<td>'.$row["status"];'</td>';
echo '<td>'.$row["will_return"];'</td>';
echo '<td></td>';
echo '</tr>';
echo '<div align="center" id="'.$i++.'" style="display:none;width:520px;">
<h2>'.$row["name"].'</h2>
<!-- <h4>Current Status: '.$row["status"].'</h4> -->
<form method="post" action="statusChange.php" />
<input type="hidden" value="'.$row["id"].'" name="id"/>
<textarea rows="4" cols="50" placeholder="Enter Comment/Status Here..." name="comment"></textarea>
<br/><br/>
When will you return? - <input type="time" name="e_time">
<br/><br/>
<input class="pure-button pure-button-primary" type="submit" value="Leave/Return">
</form>
</div>';
}
} else {
echo "0 employees";
}
echo '</tr></table>';
echo '</div></center>';
$conn->close();
UPDATE:
What is by this is that look at image below. You will notice that after the first load (5 seconds) the clickable (href) gets killed...

<script type="text/javascript">
var updateWatcher = function() {
$.ajax({
url: 'watcher.php',
success: function(response) {
$('.view').html(response);
window.setTimeout(function(){
updateWatcher();
}, 3500);
}
});
}
updateWatcher();
</script>
Granted, this could be solved more elegantly with something like promises, but as far as a simple fix you could try something like this where the timer is only setup once the response has been successfully received. This should be more reliable.
Here is a simple fiddle: http://jsfiddle.net/agentfitz/26mahomm/3/ (look in the console).

Passing an id to a PHP script using jQuery/Ajax

This is the code that the user have a participation with.
<html>
<head>
<title></title>
<script src="jquery-1.9.1.js"></script>
<script src="jquery.form.js"></script>
</head>
<body>
<?php
include 'connection.php';
$sql="SELECT * FROM blog";
$result=mysqli_query($link, $sql);
if(!$result)
{
$output='Error fetching students:'.mysqli_error($link);
}
?>
<div id="table">
<table border='1' cellpadding='10' id="table">
<tr>
<td><b>Title<b></td>
<td><b>Edit<b></td>
<td><b>Delete<b></td>
</tr>
<?php
while($row=mysqli_fetch_array($result))
{
echo '<tr class="record">';
echo '<td>'.$row['articletitle'] .'';
echo '<td>Edit';
echo "<input type='hidden' name='id' value='".$row['articleid']."'></td>";
echo '<td><div align="center">Delete</div></td>';
echo "</tr>\n";
}
echo '<form method="post" id="myForm" action="postview.php">';
echo '<input type="hidden" name="myID">';
echo '</form>';
?>
</table>
<button id="addrecord">Add New Post</button>
</div>
<script type="text/javascript">
$(document).ready(function(){
$("#addrecord").click(function(){
$("#table").load("addpost.php");
$("#addrecord").hide();
});//add
$(".delbutton").click(function(){
//Save the link in a variable called element
var element = $(this);
//Find the id of the link that was clicked
var del_id = element.attr("id");
//Built a url to send
var info = 'id=' + del_id;
if(confirm("Are you sure you want to delete this Record?"))
{
$.ajax({
type: "GET",
url: "delete.php",
data: info,
success: function(){}
});//ajax
$(this).parents(".record").animate({ backgroundColor: "#fbc7c7" }, "fast")
.animate({ opacity: "hide" }, "slow");
}
return false;
});//delete
$(".title").click(function(){
$('[name=myID]').val($(this).attr('id'));
$('#myForm').submit();
});//view
$(".edit").click(function(){
var data=$("#tryform").serialize();
$.ajax({
type: "POST",
url: "editpost.php",
data: data
}).done(function( msg ) {
$("#table").html(msg);
});//ajax
});//delete
});
</script>
</body>
</html>
and this the PHP script that the code above redirect to.
<?php
include 'connection.php';
$id=$_GET['id'];
echo $id;
$sql="SELECT * FROM blog WHERE articleid='$id'";
$result=mysqli_query($link, $sql);
echo "<table>";
$row=mysqli_fetch_array($result);
echo "<tr>";
echo "<td>".$row['articletitle'] . "</td>";
echo "<td><img src='image.php?id=$row[articleid]' width='200' height='200' /><br/></td>";
echo "<td>".$row['articlemore'] . "</td>";
echo "</tr>";
echo "</table>";
//echo "</div>";
?>
I'm having this kind of error:
Undefined index: id in C:\xampp\htdocs\ckeditor\samples\postview.php on line 4

You need to check if argument "id" is passed to the php script first
<?php
include 'connection.php';
if( (isset($_GET['id'])) && ($_GET['id'] != '') ){ //check if the argument "id" is passed to the script
$id=$_GET['id'];
echo $id;
$sql="SELECT * FROM blog WHERE articleid='$id'";
$result=mysqli_query($link, $sql);
echo "<table>";
$row=mysqli_fetch_array($result);
echo "<tr>";
echo "<td>".$row['articletitle'] . "</td>";
echo "<td><img src='image.php?id=$row[articleid]' width='200' height='200' /><br/></td>";
echo "<td>".$row['articlemore'] . "</td>";
echo "</tr>";
echo "</table>";
//echo "</div>";
}
?>

Not so much an answer to your question, but probably a good suggestion to make your code a lot cleaner- try using PHP Alternative Syntax and moving in and out of PHP to make your HTML clean.
<?php while($row=mysqli_fetch_array($result)):?>
<tr class="record">';
<td><?php echo $row['articletitle'];?>
<td>Edit
<input type='hidden' name='id' value='<?php echo $row['articleid'];?>'></td>
<td>
<div align="center">
Delete
</div>
</td>
</tr>
<?php endwhile;?>
<form method="post" id="myForm" action="postview.php">
<input type="hidden" name="myID">
</form>

$sql="SELECT * FROM blog WHERE articleid='".$id."'";
try this line

That isnt an error, but a notice, which is lowlevel It simple means $_GET['id'] doesnt hav a value
echo $example['something']; // will give undefined index notice
$example['something'] = 'abc';
echo $example['something']; // No notices
Your website should be domain.ext/?id=123, if not, this notice will show.
