WebApp for Mobile

Good day and season's greetings to all,

I would like to create a WebApp for mobile devices, I have seen many ways to do this, jQTouch, jQuery Mobile, and others.
I need some advice on which is the best solution for performance and ease of use.
I also need a simple example of how to display data from a table in a list and see the detail in another view where I can modify, delete and / or add a record.
The table structure is:

CREATE TABLE `customers` (
  `CustomerID` varchar(5) NOT NULL,
  `CompanyName` varchar(40) NOT NULL,
  `ContactName` varchar(30) DEFAULT NULL,
  `ContactTitle` varchar(30) DEFAULT NULL,
  `Address` varchar(60) DEFAULT NULL,
  `City` varchar(15) DEFAULT NULL,
  `Region` varchar(15) DEFAULT NULL,
  `PostalCode` varchar(10) DEFAULT NULL,
  `Country` varchar(15) DEFAULT NULL,
  `Phone` varchar(24) DEFAULT NULL,
  `Fax` varchar(24) DEFAULT NULL,
  PRIMARY KEY (`CustomerID`),
  KEY `City` (`City`),
  KEY `CompanyName` (`CompanyName`),
  KEY `PostalCode` (`PostalCode`),
  KEY `Region` (`Region`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Thats how a jquery mobile webapp could look like with mysql and php involved:

<?php
$link = mysql_connect('localhost', 'your_user', 'your_pw');
mysql_set_charset('utf8',$link); 

if (!$link) {
    die('Verbindung schlug fehl: ' . mysql_error());
} else {
   // echo "connection is super!". $link;
}

$selectdb = mysql_selectdb('your_db', $link);


$sql = "select * from customers limit 0,10"; // you may want to limit the results for big tables to the firs 10 by adding LIMIT 0,10 at the end of the query.
$result = mysql_query($sql);
?>
<!DOCTYPE html> 
<html> 
<head> 
	<title>Customers</title> 
	
	<meta name="viewport" content="width=device-width, initial-scale=1"> 

	<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
	<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
	<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
</head> 
<body> 

<div data-role="page" id="one">

	<div data-role="header">
		<h1>Select Customer</h1>
	</div><!-- /header -->

	<div data-role="content">	
		<h2>Get Customer Profile:</h2>
  	<ul data-role="listview" data-inset="true">
	<?php
	$html;
	while ($r = mysql_fetch_object($result)) {
		echo '<li><a href="#customer'.$r->id.'">Customer '.$r->id.' Profile</a></li>';
		$html .= '<div data-role="page" id="customer'.$r->id.'" data-theme="a">

		<div data-role="header">
			<h1>Customer '.$r->name.'</h1>
		</div><!-- /header -->
	
		<div data-role="content" data-theme="a">	
			<h2>Customer '.$r->name.'</h2>
			<p>display here the customer information.</p>	
			<p><a href="#one" data-direction="reverse" data-role="button" data-theme="b">Back to page "one"</a></p>	
			
		</div><!-- /content -->
		
		<div data-role="footer">
			<h4>Page Footer</h4>
		</div><!-- /footer -->
		</div>';
	}
	?>
	</ul>	
	</div><!-- /content -->

	<div data-role="footer">
		<h4>Page Footer</h4>
	</div><!-- /footer -->
</div><!-- /page -->
<?php
echo $html;
?>

</body>

This will create a page with all information on one html doc. If your customer table is big, ti is better to limit the query as stated in the code.

The php does the mysql query and structures the data in the page, by clicking the links in the list view the page transitions to the customer profile pages.

Good Luck!

You probably want to start with the simplest "Hello World" kind of application, and then build up from that.  This article will help you get started with the jQuery interface to the backend script (this is called AJAX), and the book will help you get an understanding of how PHP and MySQL play together.

Note that MySQL has now been officially deprecated by PHP.  A better choice might be MySQLi or PDO.

Thank you for the code you've provided, I was able to optimize it to display data in list and detail.
To complete, as I asked in the question, how do I modify, delete and / or add a record? Make a small effort for me :) thanks

There really isn't an answer short of writing your application for you and since I'm a professional programmer I can't do that for free.  But the SitePoint book will teach you everything you need to know to get started.
