I have a sample page that uses 2 PHP files and a MySql database, and I'm trying to use jQuery infinite scroll on it. How can I load the next group of data from database? For example, I have 100 records in my pictures database, and I want to show 20, and then the next 20 after some scrolling.
This is my current core:
index.php
<?php
ob_start();
require_once('images.html');
ob_end_flush();
?>
images.html

You need to add LIMIT to your queries. Example from the MySQL manual:
SELECT * FROM tbl LIMIT 5,10; # Retrieve rows 6-15
Here, 5 is the starting offset, and 10 is the amount of rows you want to fetch.
For the client-side you'll need the infinite scroll jQuery plugin.

I created a table as company_list. This table consists of following fields
1)Company Name 2) Country 3) Vertical
So, lets assume there are 5 companies as following
Company Name: Water, Earth, Sun, Moon, Star
Countries: Water= UK, Earth=UK, Sun=Australia, Moon, =India, Star=Germany
Vertical:Water, Earth, Sun = WWF and Moon, Star=Social Welfare
First HTML is a select option to filter by
1st Country 2nd Vertical
So, if I chose UK country, vertical should auto select WWF (exclude AUS country company name)
Now, post this I have button to FETCH single COMPANY DETAILS first that matches the above condition.
Code, I have designed is not adding a filter and does fetch every company.
Kindly help with this.
1) index page
<?php
$conn = mysqli_connect("localhost","root","","accounts");
$sql = "SELECT * FROM company_list";
$res= mysqli_query($conn,$sql);

Note: here you loop trough fetch data you need to add data in string array after that return data in JSON

This fairly simple issue is vexing me. I have an html page laid out with CSS. I have a simple php page that returns the latest record from a mysql site. I need to display this information in the html page in the "leftContent" div.
working 'latest.php' page is:
<?php
/*
Return the latest date and record for the left pane.
*/
include 'ESP8266_dbLogin.php';
$result = mysqli_query($link, "SELECT * FROM `thLog` ORDER BY logID DESC LIMIT 1") or die ("Connection error");
while($row = mysqli_fetch_array($result)) {
echo "Date: " . $row['logDate'] . "<br>";
echo "lightVal: " . $row['lightVal'];
}
mysqli_close($link);
?>
'index.html' code is as follows, with the target DIV of contentLeft for the php variables:
<!DOCTYPE html>
<!-- Basic Layout -->

Any help is gratefully received on the most efficient way to get the php variables (lightVal) into the html page. I know, stupid question!!
1) Rename your index.html to index.php
2) Replace your target div with your PHP code:
<div class="content" id="contentLeft">
<h2>Current Usage:</h2>
<?php
/*
Return the latest date and record for the left pane.
*/
include 'ESP8266_dbLogin.php';
$result = mysqli_query($link, "SELECT * FROM `thLog` ORDER BY logID DESC LIMIT 1") or die ("Connection error");
while($row = mysqli_fetch_array($result)) {
?>
<p class="dateClass"><?=$row['logDate']?></p>
<p class="lightValClass"><?=$row['lightVal']?></p>
<?
}
mysqli_close($link);
?>
</div>
It should be enough, just call index.php from browser.
My implementation is at : http://i.cs.hku.hk/~hsbashir/Project_Work/Listview/list_view.html
The first entry is when the list is hardcoded. Second and third ones are when they are extracted from the server using xmlhttp object. I am unable to understand why in the 2nd & 3rd list the formatting is different.

The second and third are added after the widget has been initialized. You therefore have to re-enhance (refresh) the widget each time you make an update to it. And you can do that using the $(parent_of_new_content).listview('refresh'). In your case you would have to call the following:
$('#news_mesgs').listview( 'refresh' );
Just out of curiosity, is there any particular reason why you're using plain vanilla JS for your ajax call? If you were to use jQuery (recommended) your function would be:
lastRecord=0;
function loadNews(){
$('#sample').html( 'hello' );
$.get(
"queryNews.php?lastRecord="+lastRecord,
function( data ) {
$('#news_mesgs').append( data )
.listview( 'refresh' );
}
);
}
EDIT
Please note that in the above code .enhanceWithin() has been replaced with .listview('refresh')

What i wrong with this code below. I am trying to get it to echo to another page but it does not seem to pick up the data that is on the database.

$result = mysql_query ($query) or die ("didn't query");
//this selects the results as rows
$num = mysql_num_rows ($result);
//if there is only 1 result returned than the data is ok
if ($num == 1)

please add at the top
session_start();
since you are using $_SESSION .. you need to use session_start() immediately after php opening tag
<?php
session_start();
and not only on this page .. session_start() should be there on every page where you want you use session_start() .. otherwise $_SESSION is not accessible..
Please use session_start() on both of the pages, if you dont start that you will not be able to use that
EDIT
Create a test page to see your sessions are working?
if yes then test that on other page
also try adding a simple echo in your if condition where you are setting the session values. If that echo triggers it means your code is correct and something is wrong with SESSION. And if echo dont trigger, it means your code is not correct and sessions are not being set
if your just trying to get the first row
$query = "SELECT `Appointment_id`, `Doctor_id`, `Patient_id`, `Appointment_time`, `Appointment_date` FROM `Appointment` WHERE rownum = 1 ; ";
Edit:
Ok so here I believe the logical error lies
$query = "SELECT `Appointment_id`, `Doctor_id`, `Patient_id`, `Appointment_time`, `Appointment_date` FROM `Appointment`";
$result = mysql_query ($query) or die ("didn't query");
$num = mysql_num_rows ($result);
if ($num == 1)
{
}
Since your query has no WHERE clause, it is returning all records that there are, and You are setting the SESSION values only when there is 1 record. You should also have an else condition to see what happens in real.
Create a query that selects all data from the PATIENT table where the username and password match
But your query does not do that, it gets data for all the PATIENTs
For example if your username and password came from a POSTed form then you could do
$username=mysql_real_escape_string($_POST["username"]);
$password=mysql_real_escape_string($_POST["password"]);
Then you could use both those values inside a WHERE clause. Since I do not know the structure of your tables apart from just reading your query, I can not write it exactly. But just to give you an idea, a where could be like
$query="SELECT id from YourTable where $username='$username' and password='$password'"
Very important to note since you are a beginner : mysql_* functions should no longer be used. If you are starting, don't start with something that's gone. Read about mysqli_* or PDO
Edit 2:
Ok great, so do this
On successful login where you store Patient's details in SESSION, also store Patient_id like $_SESSION['Patient_id'] = $row['Patient_id']; //or maybe its just id. Check your table
On Appointment.php change your query to
$pid=intval($_SESSION["Patient_id"]);
$query = "SELECT Appointment_id, Doctor_id, Patient_id, Appointment_time, Appointment_date FROM Appointment where Patient_id=$pid";
Add an else condition below your if($num==1) { } block like
PHP
else{
echo "Somehow we didn't get 1 record";
die();
}
Ok , so I am trying to load content from a another page using JQUERY LOAD method SO THE content can appear without the page refreshing. I did that but when I click on the link below generated from PHP , it still redirects me to the other page instead of the content loading into the <div class="panel">
Below is my code
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title> MadScore, A Social Scoring Platform </title>
<link rel="stylesheet" type="text/css" href="css/madscore.css">
<link rel="stylesheet" type="text/css" href="css/skins/tango/skin.css" />
<script type="text/javascript" src="javascript/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="javascript/jquery-1.8.3.min.js"></script>
<script type="text/javascript" src="javascript/jquery.jcarousel.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery('#mycarousel').jcarousel({
scroll: 1, buttonNextHTML:"<div></div>", buttonPrevHTML:"<div></div>"
});
});
</script>
//Here is where I made the Jquery call for the div below with class "panel" but it won't load ..
<scrip type="text/javascript">
$(document).ready(function(){
$("profile").click(function(){
$(".panel").load("this.href");
});
});
</script>
</head>
<body>
<div class="sliding-panel">
<div class="container">
<ul id="mycarousel" class="jcarousel-skin-tango">
<li>
<li>
<div class="panel"> //panel supposed to be triggered by Jquery
<h1> People </h1>
<?php
database_connect();
$query = "select * from People";
$result = $connection->query($query);
$row_count =$result->num_rows;
for($i = 1; $i <= $row_count; $i++)
{
$row = $result->fetch_assoc();
echo "<a href='/profile.php?id=".$row['ID']."' id='profile'><img src ='../".$row['Picture']."' width='100' height='100' /> </a>";
}
?>
</div>
</li>
<li>
<div class="panel">
<h1>Ballers</h1>
</div>
</li>
<li>
<div class="panel">
<h1>Movies</h1>
</div>
</li>
<li>
<div class="panel">

</div>
</li>
</ul>
There are few errors,
1 Wrong spelling of script. scrip should be script
2 wrong syntax of id selector. $("profile") should be $("#profile")
3 loading constant string instread of current element href. load("this.href") should be
load(this.href)
Change
<scrip type="text/javascript">
$(document).ready(function(){
$("profile").click(function(){
$(".panel").load("this.href");
});
});
</script>
To
<script type="text/javascript">
$(document).ready(function(){
$("#profile").click(function(){
$(".panel").load(this.href);
});
});
</script>
