Editable Grid with command buttons

To make a grid editable you need to enable the editable property and configure the ezEditTable configuration object (ezEditTable_config) nested in the table filter configuration object. This demo shows how to :

• configure the cell editors and enable the command buttons
• configure the server-side actions for insert, update and delete operations
• plug a custom date picker component and use the editor's delegates
• use custom cell data validators
• use server activity callbacks to display a loader
• use the db actions callbacks to reload the page after insert and delete operatoions
• customise the script's messages

Please note that is a live demo and your tests will be recorded in a database!

Below the server-side PHP codes for DB operations used in this demo:

Insert:

<?php
if(isset($_POST["id"]) && isset($_POST["name"]) && isset($_POST["email"])){
	$id = $_POST["id"];
	$name = echappement(utf8_urldecode($_POST["name"]));
	$email = echappement(utf8_urldecode($_POST["email"]));
	$startdate = $_POST["startdate"];
	$salary = $_POST["salary"];
	$active = $_POST["active"];
	$ip = isset($_SERVER['HTTP_X_FORWARDED_FOR']) ? $_SERVER['HTTP_X_FORWARDED_FOR'] : $_SERVER['REMOTE_ADDR'];
	if($active == 'true') $active = 1;
	else $active = 0;

	connect_db();
	$query = "INSERT INTO ".TBL_DEMO_EMPLOYEE." ".
				" VALUES('0','$name','$email','$startdate','$salary',".
				"'$ip', null, null, NOW(), null, null, $active, 0)";
	mysql_query($query);
	close_db();
}
?>
		

Update:

<?php
if(isset($_POST["id"]) && isset($_POST["name"]) && isset($_POST["email"])){
	$id = $_POST["id"];
	$name = echappement(utf8_urldecode($_POST["name"]));
	$email = echappement(utf8_urldecode($_POST["email"]));
	$startdate = $_POST["startdate"];
	$salary = $_POST["salary"];
	$active = $_POST["active"];
	$ip = isset($_SERVER['HTTP_X_FORWARDED_FOR']) ? $_SERVER['HTTP_X_FORWARDED_FOR'] : $_SERVER['REMOTE_ADDR'];
	if($active == 'true') $active = 1;
	else $active = 0;

	connect_db();
	$query = "UPDATE ".TBL_DEMO_EMPLOYEE." SET ".
				"NAME='$name',EMAIL='$email',STARTDATE='$startdate',SALARY='$salary'".
				",MODIP='$ip',MODDATE=NOW(),ACTIVE=$active ".
				"WHERE ID='$id'";
	mysql_query($query);
	close_db();
}
?>
		

Delete:

Records deleting is performed in this case via <script> tag inclusion method, ... submit_method: 'script', ... (GET http request), therefore do not forget to specify the javascript content-type in your server-side code:

<?php
header("content-type: application/x-javascript");
if(isset($_GET["id"])){
	$id = $_GET["id"];
	$ip = isset($_SERVER['HTTP_X_FORWARDED_FOR']) ? $_SERVER['HTTP_X_FORWARDED_FOR'] : $_SERVER['REMOTE_ADDR'];
	connect_db();
	$query = "UPDATE ".TBL_DEMO_EMPLOYEE." SET ".
				"DELIP='$ip',DELDATE=NOW(),DELETED=1 ".
				"WHERE ID='$id'";
	mysql_query($query);
	close_db();
}
?>
