Get current URL in JavaScript?

Get current URL in JavaScript?

I am using jQuery. How do I get the path of the current URL and assign it to a variable?

Example URL:

http://localhost/menuname.de?foo=bar&amp;number=0

Answer:

To get the path, you can use:

var pathname = window.location.pathname; // Returns path only
var url      = window.location.href;     // Returns full URL

Modify the URL without reloading the page

Is there any way I can modify the URL of the current page without reloading the page?

I would like to access the portion before the # hash if possible.

I only need to change the portion after the domain, so its not like I'm violating cross-domain policies.

 window.location.href = "www.mysite.com/page2.php";  // sadly this reloads

Answer:

This can now be done in Chrome, Safari, FF4+, and IE10pp4+!

See this question's answer for more info: Updating address bar with new URL without hash or reloading the page

Example:

 function processAjaxData(response, urlPath){
     document.getElementById("content").innerHTML = response.html;
     document.title = response.pageTitle;
     window.history.pushState({"html":response.html,"pageTitle":response.pageTitle},"", urlPath);
 }

You can then use window.onpopstate to detect the back/forward button navigation:

window.onpopstate = function(e){
    if(e.state){
        document.getElementById("content").innerHTML = e.state.html;
        document.title = e.state.pageTitle;
    }
};

For a more in-depth look at manipulating browser history see this MDN article.

Facebook API - How do I get a Facebook user's profile image through the Facebook API (without requiring the user to “Allow” the application)

Facebook API - How do I get a Facebook user's profile image through the Facebook API (without requiring the user to “Allow” the application)

I'm working on a CMS that fetches a user's profile image from their Facebook URL (that is, http://facebook.com/users_unique_url). How can I accomplish this? Is there a Faceboook API call that fetches a user's profile image URL without the user needing to Allow the application?

Answer:

Simply fetch the data through this URL:

http://graph.facebook.com/userid_here/picture

Replace userid_here with id of the user you want to get the photo of. You can also use HTTPS as well.

You can use the PHP's file_get_contents function to read that URL and process the retrieved data.

Resource:

http://developers.facebook.com/docs/api

Note: In php.ini, you need to make sure that the OpenSSL extension is enabled to use thefile_get_contents function of PHP to read that URL.

How to post data in PHP using file_get_contents?

by Blogger 4:49:00 AM file_get_contents() PHP url

How to post data in PHP using file_get_contents?

I'm using PHP's function file_get_contents() to fetch contents of a URL and then I process headers through the variable $http_response_header.

Now the problem is that some of the URLs need some data to be posted to the URL (for example, login pages).

How do I do that?

I realize using stream_context I may be able to do that but I am not entirely clear.

Thanks.

Answer:

Sending an HTTP POST request using file_get_contents is not that hard, actually : as you guessed, you have to use the $context parameter.

There's an example given in the PHP manual, at this page : HTTP context options (quoting) :

$postdata = http_build_query(
    array(
        'var1' => 'some content',
        'var2' => 'doh'
    )
);

$opts = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);

$context  = stream_context_create($opts);

$result = file_get_contents('http://example.com/submit.php', false, $context);

Basically, you have to create a stream, with the right options (there is a full list on that page), and use it as the third parameter to file_get_contents -- nothing more ;-)

As a sidenote : generally speaking, to send HTTP POST requests, we tend to use curl, which provides a lot of options an all -- but streams are one of the nice things of PHP that nobody knows about... too bad...

Saving image from PHP URL

by Blogger 4:47:00 AM cURL PHP Save Image url

Saving image from PHP URL

I need to save an image from a PHP URL to my PC. Let's say I have a page, http://example.com/image.php, holding a single "flower" image, nothing else. How can I save this image from the URL with a new name (using PHP)?

Answer:

If you have allow_url_fopen set to true:

$url = 'http://example.com/image.php';
$img = '/my/folder/flower.gif';
file_put_contents($img, file_get_contents($url));

Else use cURL:

$ch = curl_init('http://example.com/image.php');
$fp = fopen('/my/folder/flower.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);

How to get current page URL in PHP

get url in PHP function here Use the PHP $_SERVER Superglobal Variable

You can use the $_SERVER built-in variable to get the current page URL in PHP. The $_SERVER is a superglobal variable, which means it is always available in all scopes.

Also if you want full URL of the page you'll need to check the scheme name (or protocol), whether it is http or https as shown in the example below:

<?php
$uri = $_SERVER['REQUEST_URI'];
echo $uri; // Outputs: URI
 
$protocol = ((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
 
$url = $protocol . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
echo $url; // Outputs: Full URL
 
$query = $_SERVER['QUERY_STRING'];
echo $query; // Outputs: Query String
?>

Remove .php extension (explicitly written) for friendly URL

by Blogger 9:52:00 PM friendly URL htaccess PHP url

Remove .php extension (explicitly written) for friendly URL

htaccess to remove the .php extension of my site's files.

RewriteEngine on
RewriteBase /
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^(.*)$ $1.php [L,QSA]

Now, if I go to my site

www.mysite.com/home

works fine, it redirects to home.php but the URL is still friendly.

But if I write this URL:

www.mysite.com/home.php

The home.php is served, and the URL is not friendly.

How can I avoid this behavior? I want that if the user writes www.mysite.com/home.php, the URL displayed in the URL bar be www.mysite.com/home

Answer :

remove .php from requests like so

RewriteCond %{REQUEST_URI} ^/(.*).php$
RewriteRule ^(.*)$ %1 [L,QSA]
