Imagine any webpage ex: example1.com/something... using this html:
<img src="http://www.example2.com/controller/showImage" >
My controller in web2.com is something like:
function showImage() {
getIP(); //return USER IP (working)
getURL(); //return example1.com/something... (not working it returns always 'http://www.example2.com/controller/showImage')
addMetricsSQL($ip, $url); //add ip and url in database (working)
header('Content-Type: image/jpeg'); //headers
readfile($this->$path_img); //a path
}
My current function is:
public function getURL() {
$ssl = ( ! empty( $_SERVER['HTTPS'] ) && $_SERVER['HTTPS'] == 'on' );
$sp = strtolower( $_SERVER['SERVER_PROTOCOL'] );
$protocol = substr( $sp, 0, strpos( $sp, '/' ) ) . ( ( $ssl ) ? 's' : '' );
$port = $_SERVER['SERVER_PORT'];
$port = ( ( ! $ssl && $port=='80' ) || ( $ssl && $port=='443' ) ) ? '' : ':'.$port;
$host = ( false && isset( $_SERVER['HTTP_X_FORWARDED_HOST'] ) ) ? $_SERVER['HTTP_X_FORWARDED_HOST'] : ( isset( $_SERVER['HTTP_HOST'] ) ? $_SERVER['HTTP_HOST'] : null );
$host = isset( $host ) ? $host : $_SERVER['SERVER_NAME'] . $port;
return $protocol . '://' . $host . $_SERVER['REQUEST_URI'];
}
But like I said, it only returns example2.com/controller/showImage
My questions:
Is posible to get the right URL(in this case
example1.com/something...) using PHP?
How the getURL() function should be?
Thanks in advance
It was painfull but the answer to my question is:
public function getURL() {
return getenv('HTTP_REFERER', true) ?: getenv('HTTP_REFERER');
}
HTTP_REFERER Makes all the magic.

I've recently become the maintainer of a Wordpress site (I'm completely new to wordpress) and I'm having some difficulty determining where a redirect is specified.
I've checked the .htaccess file, and there's nothing specified in there. As far as I can tell, the rewrite rules aren't the cause.
I've tried deleting the page being redirected from and re-creating it, and the redirect still occurs.
My question is: where can you specify a redirect? I've run out of ideas of where to look.
one of my client want to custom url like
https://www.qsleap.com/gmat/resources as you know in wordpress evry request is catch by index.php . request filter catches the request and
call the page .
Read this code it may give you any idea.
function permalinks_customizer_request_before($query ){
$uri=$_SERVER['REQUEST_URI'];
$match= preg_match('/(gmat|gre|sat|lsat|cat)(\/resources\/tags\/)
(.*)\/(articles|videos|concept-notes|qna)/', $uri,$matches);
//$match=
preg_match('/(gmat|gre|sat|lsat|cat)/\resources/\tags/stanford-
gsb/\articles|videos|concept-notes)/?$', $uri,$matches);
if($match){
$url = parse_url( get_bloginfo( 'url' ) );
$url = isset( $url['path']) ? $url['path'] : '';
$request = ltrim( substr( $_SERVER['REQUEST_URI'], strlen( $url ) ), '/' );
$request = ( ( $pos = strpos( $request, '?' ) ) ? substr( $request, 0, $pos ) : $request );
if ( ! $request )
return $query;
$original_url="?page_name=tags&exam=".$matches[1]."&post_tag=".$matches[3]."&post_type=".$matches[4];
if ( $original_url !== null ) {
$original_url = str_replace('//', '/', $original_url);
if ( ( $pos = strpos( $_SERVER['REQUEST_URI'], '?' ) ) !== false ) {
$queryVars = substr( $_SERVER['REQUEST_URI'], $pos + 1 );
$original_url .= ( strpos( $original_url, '?' ) === false ? '?' : '&') . $queryVars;
}
$oldRequestUri = $_SERVER['REQUEST_URI'];
$oldQueryString = $_SERVER['QUERY_STRING'];
$_SERVER['REQUEST_URI'] = '/' . ltrim( $original_url, '/' );
$_SERVER['QUERY_STRING'] = ( ( $pos = strpos( $original_url, '?' ) ) !== false ? substr( $original_url, $pos + 1 ) : '' );
parse_str( $_SERVER['QUERY_STRING'], $queryArray );
$oldValues = array();
global $wp;
$wp->parse_request();
$query = $wp->query_vars;
if ( is_array( $queryArray ) ) {
foreach ( $queryArray as $key => $value ) {
$oldValues[$key] = $_REQUEST[$key];
$_REQUEST[$key] = $_GET[$key] = $value;
$query[$key]=$value;
}
}
$_SERVER['REQUEST_URI'] ='';
$_SERVER['QUERY_STRING']='';
}
}
return $query;
}
add_filter( 'request','permalinks_customizer_request_before',0);
function wp_url_rewrite_templates() {
if (get_query_var( 'page_name' ) && get_query_var( 'page_name'
)=='tags') {
add_filter( 'template_include', function() {
$template= dirname( __FILE__ ) . '/page-tags.php';
return $template;
});
}
}

I think the easiest way for you to remove the redirects will be with this plugin.
https://redirection.me/
After you install it and activate it. From the Wordpress Admin
Tools > Redirection
You'll see a list of redirects, and add/remove any.
I am new to php.
I am using Wordpress and yoast.
However, the yoast plugin is not writing the canonical correctly. I wish to write the canonical so that it uses the syntax
<link rel="canonical" href="https://www.travelideology.com/about/">
However, it is writing
<link rel="canonical" href="https:/about/">
Would be happy if someone can let me know what is wrong with my code.
The code is as follows:
function my_wpseo_canonical( $canonical ) {
global $post;
$attachment = get_post( $post->ID );
$protocol = ($_SERVER['HTTPS'] && $_SERVER['HTTPS'] != "off") ? "https" : "http";
$cleansed = $protocol . "://" . $_SERVER['HTTP_HOST'];
$cleansed2 = get_permalink($attachment);
$canonical = $cleansed . $cleansed2;
return $canonical;
}
add_filter( 'wpseo_canonical', 'my_wpseo_canonical' );
try
function my_wpseo_canonical( $canonical ) {
global $post;
$attachment = get_post( $post->ID );
$protocol = ($_SERVER['HTTPS'] && $_SERVER['HTTPS'] != "off") ? "https" : "http";
$cleansed = $protocol . "://" .site_url(). $_SERVER['HTTP_HOST'];
$cleansed2 = get_permalink($attachment);
$canonical = $cleansed . $cleansed2;
return $canonical;
}
I have this code that is ment to stop people entering dots and slashes into query strings.
The string is defined to a variable, then if the variable containes a '.' or a '/' i would like to replace them with forbidden and main.
<?php
if( strpos( $page, '/' ) === true ) { $page = 'forbidden'; $inner_page = 'main'; }
elseif( strpos( $page, '.' ) === true ) { $page = 'forbidden'; $inner_page = 'main'; }
elseif( strpos( $inner_page, '/' ) === true ) { $page = 'forbidden'; $inner_page = 'main'; }
elseif( strpos( $inner_page, '.' ) === true ) { $page = 'forbidden'; $inner_page = 'main'; }
?>
This code (isAllowedURL.php) is being loaded into this code:
<?php
$page = 'home';
$inner_page = 'main';
if( isset( $_GET['page'] ) )
{
$page = htmlspecialchars( $_GET['page'] );
}
if( isset( $_GET['subpage'] ) )
{
$inner_page = htmlspecialchars( $_GET['subpage'] );
}
include ('/indexBuilder/linkSecurity/isAllowedURL.php');
?>
As you can see, it changes the variables to the query if it exists and i would like to change it back if the variable containes the banned characters.
Why does this code not function as wanted?
-I changed the true to false and every page was made forbidden, changed it back and none where.
SOLVED:
You need to use !== to see if they are present. Also you cannot use true with strpos.
if( strpos( $page, '/' ) !== false ) { $page = 'forbidden'; $inner_page = 'main'; }
I want to get a URL and its parameters. Example:
www.someweb.com/somepage.php?id=10
How to get only somepage.php?id=10?
I'm already tried REQUEST_URI and PHP_SELF but it only gives me www.someweb.com/somepage.php or somepage.php. What I want to is just the page name and its parameter(s).
basename($_SERVER['REQUEST_URI']);
This will return all URLs with page name. (e.g.: index.php?id=1&name=rr&class=10).
for complette URL with protocol, servername and parameters:
$base_url = ( isset($_SERVER['HTTPS']) && $_SERVER['HTTPS']=='on' ? 'https' : 'http' ) . '://' . $_SERVER['HTTP_HOST'];
$url = $base_url . $_SERVER["REQUEST_URI"];
$_SERVER['PHP_SELF'] for the page name and $_GET['id'] for a specific parameter.
try print_r($_GET); to print out all the parameters.
for your request echo $_SERVER['PHP_SELF']."?id=".$_GET['id'];
return all the parameters echo $_SERVER['PHP_SELF']."?".$_SERVER['QUERY_STRING'];
function curPageName() {
return substr($_SERVER["SCRIPT_NAME"],strrpos($_SERVER["SCRIPT_NAME"],"/")+1);
}
echo "The current page is ".curPageName()."?".$_SERVER['QUERY_STRING'];
This will get you page name , it will get the string after the last slash
Here's probably what you are looking for: php-get-url-query-string. You can combine it with other suggested $_SERVER parameters.
Here's a very thorough function I use to get the full URL:
function get_full_url( bool $include_query = true ) {
$protocol = ( ! empty( $_SERVER['HTTPS'] ) && strtolower( $_SERVER['HTTPS'] ) !== 'off' )
|| ( isset( $_SERVER['HTTP_X_FORWARDED_PROTO'] ) && strtolower( $_SERVER['HTTP_X_FORWARDED_PROTO'] ) === 'https' )
|| ( ! empty( $_SERVER['HTTP_FRONT_END_HTTPS'] ) && strtolower( $_SERVER['HTTP_FRONT_END_HTTPS'] ) !== 'off' )
|| ( isset( $_SERVER['SERVER_PORT'] ) && intval( $_SERVER['SERVER_PORT'] ) === 443 ) ? 'https' : 'http';
$uri = $protocol . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
return $include_query ? $uri : str_replace( '?' . $_SERVER['QUERY_STRING'], '', $uri );
}
