I have developing the one application using titanium.
Here the values are inserted successfully.But i didn't get the success message from webservices code.
I have using following code for insert a databaase :
In titanium side code :
function StaffRegistration(){
if($.staff_firstname.value != "" && $.staff_firstname.value != null){
var request = Ti.Network.createHTTPClient({
onload:alert(this.responseText),
onerror: function(e){
Ti.API.debug(e.error);
alert(this.responseText);
},
timeout:1000,
});
request.open("POST","xxx/xxx.php");
var params = ({"staff_firstname": $.staff_firstname.value,"staff_email": $.staff_email.value,"staff_password": $.staff_password.value,});
request.send(params);
}
else{
alert("Please enter the firstname");
}
Ti.API.info("Result for registration = " + this.responseText);
};
I have using a following php(webservice code) :
<?php
$request = base64_decode($_POST['jsondata']);
$data = json_decode($request,true);
$staff_firstname = $data['staff_firstname'];
$staff_email = $data['staff_email'];
$staff_password = md5($data['staff_password']);
include "db_connect.php";
$db = new DB_CONNECT();
$result = mysql_query("SELECT staff_email,staff_firstname from at_staff WHERE staff_email = '$staff_email'");
$no_of_rows = mysql_num_rows($result);
if ($no_of_rows > 0) {
while($queryresult=mysql_fetch_array($result)) {
$uname[]=$queryresult['staff_firstname'];
$uemail[]=$queryresult['staff_email'];
}
if(in_array($staff_firstname,$uname) and in_array($staff_email,$uemail)) {
$response='{"Error":"1","Message":"Username and Email already exist"}';
echo $response;
} else if (in_array($staff_firstname,$uname)) {
$response='{"Error":"1","Message":"Username already exist"}';
echo $response;
} else {
$response='{"Error":"1","Message":"Email already exist"}';
echo $response;
}
} else {
$response='{"Error":"1","Message":"Successfully Registered"}';
echo $response;
$data=array("staff_firstname"=>"'".$staff_firstname."'",
"staff_email"=>"'".$staff_email."'",
"staff_password"=>"'".$staff_password."'"
);
echo $response;
}
?>
How can i get the $response in titanium from this webservice url.
#user2218667
Ti.API.info("Result for registration = " + this.responseText);
will NEVER work as you show in the first piece of code .
why ? because you send a request which will take like 1 seconde (for exemple), obviously, your programm won't wait 1 sec after
request.send(params);
i will continue the programm and when the request return a result, it will get into
onload(e) :
and here only you will be able to have your $result.
is this ok? well now, if this.responseData isn't effective, I don't have the solution .Can you check your line : "} else {" ,i supose there is a if above in the code? are you sure $result is defined upper?
Can you try the same request without titanium with a basic html form to be sure $result is write correctly in this case, like this, we will know if the problem come from php or from the link betwin php & titanium.
well , i supose it's asynchronous request, so the folowing may not work
Ti.API.info("Result for registration = " + this.responseText);
coud you try :
onload : function(e) {
Ti.API.info(this.responseText); // maybe Ti.API.info(this.reponsedata) according to your php.
},
onerror : function(e) {...
in my mind, if you receive JSON information (it trully look's like), you need
this.responseData //instead of this.responseText
I'm playing around a little with Ajax and i'm using the following code.
var r = new XMLHttpRequest();
r.open("POST", "pythonTesting.php", true);
r.onreadystatechange = function () {
if (r.readyState === 4 && r.status === 200) {
alert("Success: " + r.responseText);
}
};
r.send("text=yellow");
It is successful but the alert isn't showing the actual responseText.
pythonTesting.php (not to be confused by the name) is just:
<?php
echo $_POST['text'];
?>
I'm expecting the responseText to be yellow because that's how I sent it but its not. I'm not really seeing what the problem is though. It must be one of those easy to fix mistakes.
from http://www.w3schools.com/ajax/ajax_xmlhttprequest_send.asp:
xmlhttp.open("POST","ajax_test.asp",true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send("fname=Henry&lname=Ford");
Since this is a post I believe you will need to set the length:
r.setRequestHeader("Content-length", "text=yellow".length);
send the variables through the address:
r.open("POST", "pythonTesting.php?text=yellow", true);
then retrieve the variable in php by
$text = $_REQUEST['text'];
I'm trying to figure out the visitor's OS is either a Windows, Mac or Linux using PHP(I don't need the version, distro info.. etc). There's several methods out there however they look a bit too complicated for this simple requirement.
Are there any simple ways that could provide this sort of information yet still being quite reliable?
Thanks in advance.
<?php
$agent = $_SERVER['HTTP_USER_AGENT'];
if(preg_match('/Linux/',$agent)) $os = 'Linux';
elseif(preg_match('/Win/',$agent)) $os = 'Windows';
elseif(preg_match('/Mac/',$agent)) $os = 'Mac';
else $os = 'UnKnown';
echo $os;
?>
For an easy solution have a look here.
The user-agent header might reveal some OS information, but i wouldn't count on that.
For your use case i would do an ajax call using javascript from the client side to inform your server of the client's OS. And do it waterproof.
Here is an example.
Javascript (client side, browser detection + ajax call ):
window.addEvent('domready', function() {
if (BrowserDetect) {
var q_data = 'ajax=true&browser=' + BrowserDetect.browser + '&version=' + BrowserDetect.version + '&os=' + BrowserDetect.OS;
var query = 'record_browser.php'
var req = new Request.JSON({url: query, onComplete: setSelectWithJSON, data: q_data}).post();
}
});
PHP (server side):
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$session = session_id();
$user_id = isset($user_id) ? $user_id : 0;
$browser = isset($_POST['browser']) ? $_POST['browser'] : '';
$version = isset($_POST['version']) ? $_POST['version'] : '';
$os = isset($_POST['os']) ? $_POST['os'] : '';
// now do here whatever you like with this information
}
use the Net_UserAgent package
docu is here: http://pear.php.net/package/Net_UserAgent_Detect/docs/latest/Net_UserAgent/Net_UserAgent_Detect.html#methodgetOSString
get the php file here:
package/Net_UserAgent_Detect/docs/latest/__filesource/fsource_Net_UserAgent__Net_UserAgent_Detect-2.5.1Detect.php.html
I need to find the screen resolution of a users screen who visits my website?
You can't do it with pure PHP. You must do it with JavaScript. There are several articles written on how to do this.
Essentially, you can set a cookie or you can even do some Ajax to send the info to a PHP script. If you use jQuery, you can do it something like this:
jquery:
$(function() {
$.post('some_script.php', { width: screen.width, height:screen.height }, function(json) {
if(json.outcome == 'success') {
// do something with the knowledge possibly?
} else {
alert('Unable to let PHP know what the screen resolution is!');
}
},'json');
});
PHP (some_script.php)
<?php
// For instance, you can do something like this:
if(isset($_POST['width']) && isset($_POST['height'])) {
$_SESSION['screen_width'] = $_POST['width'];
$_SESSION['screen_height'] = $_POST['height'];
echo json_encode(array('outcome'=>'success'));
} else {
echo json_encode(array('outcome'=>'error','error'=>"Couldn't save dimension info"));
}
?>
All that is really basic but it should get you somewhere. Normally screen resolution is not what you really want though. You may be more interested in the size of the actual browser's view port since that is actually where the page is rendered...
Directly with PHP is not possible but...
I write this simple code to save screen resolution on a PHP session to use on an image gallery.
<?php
session_start();
if(isset($_SESSION['screen_width']) AND isset($_SESSION['screen_height'])){
echo 'User resolution: ' . $_SESSION['screen_width'] . 'x' . $_SESSION['screen_height'];
} else if(isset($_REQUEST['width']) AND isset($_REQUEST['height'])) {
$_SESSION['screen_width'] = $_REQUEST['width'];
$_SESSION['screen_height'] = $_REQUEST['height'];
header('Location: ' . $_SERVER['PHP_SELF']);
} else {
echo '<script type="text/javascript">window.location = "' . $_SERVER['PHP_SELF'] . '?width="+screen.width+"&height="+screen.height;</script>';
}
?>
New Solution If you need to send another parameter in Get Method (by Guddu Modok)
<?php
session_start();
if(isset($_SESSION['screen_width']) AND isset($_SESSION['screen_height'])){
echo 'User resolution: ' . $_SESSION['screen_width'] . 'x' . $_SESSION['screen_height'];
print_r($_GET);
} else if(isset($_GET['width']) AND isset($_GET['height'])) {
$_SESSION['screen_width'] = $_GET['width'];
$_SESSION['screen_height'] = $_GET['height'];
$x=$_SERVER["REQUEST_URI"];
$parsed = parse_url($x);
$query = $parsed['query'];
parse_str($query, $params);
unset($params['width']);
unset($params['height']);
$string = http_build_query($params);
$domain=$_SERVER['PHP_SELF']."?".$string;
header('Location: ' . $domain);
} else {
$x=$_SERVER["REQUEST_URI"];
$parsed = parse_url($x);
$query = $parsed['query'];
parse_str($query, $params);
unset($params['width']);
unset($params['height']);
$string = http_build_query($params);
$domain=$_SERVER['PHP_SELF']."?".$string;
echo '<script type="text/javascript">window.location = "' . $domain . '&width="+screen.width+"&height="+screen.height;</script>';
}
?>
PHP is a server side language - it's executed on the server only, and the resultant program output is sent to the client. As such, there's no "client screen" information available.
That said, you can have the client tell you what their screen resolution is via JavaScript. Write a small scriptlet to send you screen.width and screen.height - possibly via AJAX, or more likely with an initial "jump page" that finds it, then redirects to http://example.net/index.php?size=AxB
Though speaking as a user, I'd much prefer you to design a site to fluidly handle any screen resolution. I browse in different sized windows, mostly not maximized.
Easiest way
<?php
//-- you can modified it like you want
echo $width = "<script>document.write(screen.width);</script>";
echo $height = "<script>document.write(screen.height);</script>";
?>
I found using CSS inside my html inside my php did the trick for me.
<?php
echo '<h2 media="screen and (max-width: 480px)">';
echo 'My headline';
echo '</h2>';
echo '<h1 media="screen and (min-width: 481px)">';
echo 'My headline';
echo '</h1>';
?>
This will output a smaller sized headline if the screen is 480px or less.
So no need to pass any vars using JS or similar.
You can check it like below:
if(strstr(strtolower($_SERVER['HTTP_USER_AGENT']), 'mobile') || strstr(strtolower($_SERVER['HTTP_USER_AGENT']), 'android')) {
echo "mobile web browser!";
} else {
echo "web browser!";
}
This is a very simple process. Yes, you cannot get the width and height in PHP. It is true that JQuery can provide the screen's width and height. First go to https://github.com/carhartl/jquery-cookie and get jquery.cookie.js. Here is example using php to get the screen width and height:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Test</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js"></script>
<script src="js/jquery.cookie.js"></script>
<script type=text/javascript>
function setScreenHWCookie() {
$.cookie('sw',screen.width);
$.cookie('sh',screen.height);
return true;
}
setScreenHWCookie();
</script>
</head>
<body>
<h1>Using jquery.cookie.js to store screen height and width</h1>
<?php
if(isset($_COOKIE['sw'])) { echo "Screen width: ".$_COOKIE['sw']."<br/>";}
if(isset($_COOKIE['sh'])) { echo "Screen height: ".$_COOKIE['sh']."<br/>";}
?>
</body>
</html>
I have a test that you can execute: http://rw-wrd.net/test.php
Use JavaScript (screen.width and screen.height IIRC, but I may be wrong, haven't done JS in a while). PHP cannot do it.
Fully Working Example
I couldn't find an actual working PHP example to "invisibly" (without URL parameters) return client screen size, and other properties, to server-side PHP, so I put this example together.
JS populates and submits a hidden form (scripted by PHP from an array of JS properties), POSTing to itself (the data now available in PHP) and returns the data in a table.
(Tested in "several" browsers.)
<!DOCTYPE html>
<html>
<head>
<title>*Client Info*</title>
<style>table,tr{border:2px solid gold;border-collapse:collapse;}td{padding:5px;}</style>
</head>
<body>
<?php
$clientProps=array('screen.width','screen.height','window.innerWidth','window.innerHeight',
'window.outerWidth','window.outerHeight','screen.colorDepth','screen.pixelDepth');
if(! isset($_POST['screenheight'])){
echo "Loading...<form method='POST' id='data' style='display:none'>";
foreach($clientProps as $p) { //create hidden form
echo "<input type='text' id='".str_replace('.','',$p)."' name='".str_replace('.','',$p)."'>";
}
echo "<input type='submit'></form>";
echo "<script>";
foreach($clientProps as $p) { //populate hidden form with screen/window info
echo "document.getElementById('" . str_replace('.','',$p) . "').value = $p;";
}
echo "document.forms.namedItem('data').submit();"; //submit form
echo "</script>";
}else{
echo "<table>";
foreach($clientProps as $p) { //create output table
echo "<tr><td>".ucwords(str_replace('.',' ',$p)).":</td><td>".$_POST[str_replace('.','',$p)]."</td></tr>";
}
echo "</table>";
}
?>
<script>
window.history.replaceState(null,null); //avoid form warning if user clicks refresh
</script>
</body>
</html>
The returned data is extract'd into variables. For example:
window.innerWidth is returned in $windowinnerWidth
You can try RESS (RESponsive design + Server side components), see this tutorial:
http://www.lukew.com/ff/entry.asp?1392
You can set window width in cookies using JS in front end and you can get it in PHP:
<script type="text/javascript">
document.cookie = 'window_width='+window.innerWidth+'; expires=Fri, 3 Aug 2901 20:47:11 UTC; path=/';
</script>
<?PHP
$_COOKIE['window_width'];
?>
I don't think you can detect the screen size purely with PHP but you can detect the user-agent..
<?php
if ( stristr($ua, "Mobile" )) {
$DEVICE_TYPE="MOBILE";
}
if (isset($DEVICE_TYPE) and $DEVICE_TYPE=="MOBILE") {
echo '<link rel="stylesheet" href="/css/mobile.css" />'
}
?>
Here's a link to a more detailed script: PHP Mobile Detect
Here is the Javascript Code: (index.php)
<script>
var xhttp = new XMLHttpRequest();
xhttp.open("POST", "/sqldb.php", true);
xhttp.send("screensize=",screen.width,screen.height);
</script>
Here is the PHP Code: (sqldb.php)
$data = $_POST['screensize'];
$pdo = new PDO('mysql:host=localhost;dbname=test', 'username', 'password');
$statement = $pdo->prepare("UPDATE users SET screen= :screen WHERE id = $userid");
$statement->execute(array('screen' => $data));
I hope that you know how to get the $userid from the Session,
and for that you need an Database with the Table called users, and an Table inside users called screen ;=)
Regards KSP
The only way is to use javascript, then get the javascript to post to it to your php(if you really need there res server side). This will however completly fall flat on its face, if they turn javascript off.
JS:
$.ajax({
url: "ajax.php",
type: "POST",
data: "width=" + $("body").width(),
success: function(msg) {
return true;
}
});
ajax.php
if(!empty($_POST['width']))
$width = (int)$_POST['width'];
This can be done easily using cookies. This method allows the page to check the stored cookie values against the screen height and width (or browser view port height and width values), and if they are different it will reset the cookie and reload the page. The code needs to allow for user preferences. If persistant cookies are turned off, use a session cookie. If that doesn't work you have to go with a default setting.
Javascript: Check if height & width cookie set
Javascript: If set, check if screen.height & screen.width (or whatever you want) matches the current value of the cookie
Javascript: If cookie not set or it does not match the current value, then:
a. Javascript: create persistent or session cookie named (e.g.) 'shw' to value of current screen.height & screen.width.
b. Javascript: redirect to SELF using window.location.reload(). When it reloads, it will skip the step 3.
PHP: $_COOKIE['shw'] contains values.
Continue with PHP
E.g., I am using some common cookie functions found on the web. Make sure setCookie returns the correct values.
I put this code immediately after the head tag. Obviously the function should be in a a source file.
<head>
<script src="/include/cookielib.js"></script>
<script type=text/javascript>
function setScreenHWCookie() {
// Function to set persistant (default) or session cookie with screen ht & width
// Returns true if cookie matches screen ht & width or if valid cookie created
// Returns false if cannot create a cookies.
var ok = getCookie( "shw");
var shw_value = screen.height+"px:"+screen.width+"px";
if ( ! ok || ok != shw_value ) {
var expires = 7 // days
var ok = setCookie( "shw", shw_value, expires)
if ( ok == "" ) {
// not possible to set persistent cookie
expires = 0
ok = setCookie( "shw", shw_value, expires)
if ( ok == "" ) return false // not possible to set session cookie
}
window.location.reload();
}
return true;
}
setScreenHWCookie();
</script>
....
<?php
if( isset($_COOKIE["shw"])) {
$hw_values = $_COOKIE["shw"];
}
PHP works only on server side, not on user host. Use JavaScript or jQuery to get this info and send via AJAX or URL (?x=1024&y=640).
The quick answer is no, then you are probably asking why can't I do that with php. OK here is a longer answer. PHP is a serverside scripting language and therefor has nothing to do with the type of a specific client. Then you might ask "why can I then get the browser agent from php?", thats because that information is sent with the initial HTTP headers upon request to the server. So if you want client information that's not sent with the HTTP header you must you a client scripting language like javascript.
For get the width screen or the height screen
1- Create a PHP file (getwidthscreen.php) and write the following commands in it
PHP (getwidthscreen.php)
<div id="widthscreenid"></div>
<script>
document.getElementById("widthscreenid").innerHTML=screen.width;
</script>
2- Get the width screen through a cURL session by the following commands
PHP (main.php)
$ch = curl_init( 'http://hostname/getwidthscreen.php' );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
$result = curl_exec( $ch );
print_r($result);
curl_close( $ch );
Well, I have another idea, thanks to which it is 90% possible in a very simple way using pure PHP. We will not immediately know the exact screen resolution, but we will find out whether the user is using a computer (higher resolution) or a phone (lower resolution) and thanks to this we will be able to load specific data.
Code example:
$user_agent = $_SERVER['HTTP_USER_AGENT'];
if (strpos($user_agent, 'Windows') !== false) {
//PC, high resolution
//*note for phone is: Windows Phone
} elseif (strpos($user_agent, 'Mac') !== false) {
//PC, high resolution
} else {
//mobile, small resolution
//Android, iOS, Windows Phone, Blackberry OS, Symbian OS, Bada OS, Firefox OS, WebOS, Tizen OS, KaiOS, Sailfish OS, Ubuntu Touch, HarmonyOS, EMUI, OxygenOS, One UI, Magic UI, ColorOS, MiUI, OxygenOS, ZenUI, LG UX, FunTouch OS, Flyme OS, OxygenOS, Samsung One UI, Android One, Android Go, Android TV, Android Auto, Fuchsia OS.
}
Then, a great solution to complete the verification is to throw a cookie and check the data using PHP.
//JS:
function setCookieResolution() {
// Get screen resolution
if (!getCookieValue("screen_resolution")) {
var screenResolution = window.screen.width + "x" + window.screen.height;
// Create cookie with resolution info
document.cookie = "screen_resolution=" + screenResolution + ";path=/";
}
}
setCookieResolution();
//PHP:
if (isset($_COOKIE["screen_resolution"])) {
$currentValue = $_COOKIE["screen_resolution"];//example: 1920x1080
$parts = explode("x", $currentValue);
if(count($parts) == 2 && is_numeric($parts[0]) && is_numeric($parts[1])) {
$width = (int)$parts[0];
$height = (int)$parts[1];
} else {
// handle error
}
}
In PHP there is no standard way to get this information. However, it is possible if you are using a 3rd party solution. 51Degrees device detector for PHP has the properties you need:
$_51d['ScreenPixelsHeight']
$_51d['ScreenPixelsWidth']
Gives you Width and Height of user's screen in pixels. In order to use these properties you need to download the detector from sourceforge. Then you need to include the following 2 lines in your file/files where it's necessary to detect screen height and width:
<?php
require_once 'path/to/core/51Degrees.php';
require_once 'path/to/core/51Degrees_usage.php';
?>
Where path/to/core is path to 'Core' directory which you downloaded from sourceforge. Finally, to use the properties:
<?php
echo $_51d['ScreenPixelsHeight']; //Output screen height.
echo $_51d['ScreenPixelsWidth']; //Output screen width.
?>
Keep in mind these variables can contain 'Unknown' value some times, when the device could not be identified.
solution: make scalable web design ... ( our should i say proper web design) formating should be done client side and i did wish the info would be passed down to server but the info is still usefull ( how many object per rows kind of deal ) but still web design should be fluid thus each row elements should not be put into tables unless its an actual table ( and the data will scale to it's individual cells) if you use a div you can stack each elements next to each other and your window should "break" the row at the proper spot. ( just need proper css)
<script type="text/javascript">
if(screen.width <= 699){
<?php $screen = 'mobile';?>
}else{
<?php $screen = 'default';?>
}
</script>
<?php echo $screen; ?>
