replace underscores with dashes in codeigniter URL structure - php

im having a website which is developed using codeigniter. My URL strcuture has around 4 segments and over 500 pages. Currently my URL has underscores (_) but i need to replace it which dashes (-)
current structure
mywebsite.com/app/standalone_apps/high_runner_beta/download
required URL structure
mywebsite.com/app/standalone-apps/high-runner-beta/download
i cant user the routing feature in CI coz there are too many links that needs to be redirected.
i did try the solutions in
Codeigniter Routes regex - using dashes in controller/method names
but it didn't work.
can someone suggest a method where i can replace the underscores with dashes on my URLs.

This work for me -> create a a php file: MY_Route.php
with this code and upload to 'application/core' directory:
<?php class MY_Router extends CI_Router {
function set_class($class)
{
$this->class = str_replace('-', '_', $class);
}
function set_method($method)
{
$this->method = str_replace('-', '_', $method);
}
function set_directory($dir) {
$this->directory = $dir.'/';
}
function _validate_request($segments)
{
if (count($segments) == 0)
{
return $segments;
}
// Does the requested controller exist in the root folder?
if (file_exists(APPPATH.'controllers/'.str_replace('-', '_', $segments[0]).'.php'))
{
return $segments;
}
// Is the controller in a sub-folder?
if (is_dir(APPPATH.'controllers/'.$segments[0]))
{
// Set the directory and remove it from the segment array
$this->set_directory($segments[0]);
$segments = array_slice($segments, 1);
while(count($segments) > 0 && is_dir(APPPATH.'controllers/'.$this->directory.$segments[0]))
{
// Set the directory and remove it from the segment array
$this->set_directory($this->directory . $segments[0]);
$segments = array_slice($segments, 1);
}
if (count($segments) > 0)
{
// Does the requested controller exist in the sub-folder?
if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().str_replace('-', '_', $segments[0]).'.php'))
{
if ( ! empty($this->routes['404_override']))
{
$x = explode('/', $this->routes['404_override']);
$this->set_directory('');
$this->set_class($x[0]);
$this->set_method(isset($x[1]) ? $x[1] : 'index');
return $x;
}
else
{
show_404($this->fetch_directory().$segments[0]);
}
}
}
else
{
// Is the method being specified in the route?
if (strpos($this->default_controller, '/') !== FALSE)
{
$x = explode('/', $this->default_controller);
$this->set_class($x[0]);
$this->set_method($x[1]);
}
else
{
$this->set_class($this->default_controller);
$this->set_method('index');
}
// Does the default controller exist in the sub-folder?
if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$this->default_controller.'.php'))
{
$this->directory = '';
return array();
}
}
return $segments;
}
// If we've gotten this far it means that the URI does not correlate to a valid
// controller class. We will now see if there is an override
if ( ! empty($this->routes['404_override']))
{
$x = explode('/', $this->routes['404_override']);
$this->set_class($x[0]);
$this->set_method(isset($x[1]) ? $x[1] : 'index');
return $x;
}
// Nothing else to do at this point but show a 404
show_404($segments[0]);
} }

How to remove part of path until a given directory is found?

I have paths that goes like this template:
`/dir1/dir2/dirN/dirNplus1/dirNplus2/`
And for an example to demonstrate this template:
`/var/www/sei/modules/module1/`
I would like to be able to have a function where I could input a full path and a specific directory and get in return only the right part of the path, removing the left part including the directory specified in the parameter.
In the example given, if I would use:
`function('/var/www/sei/modules/module1/', 'sei')`
Then I would like to get the result as:
`/modules/module1/`
Any ideas on how to achieve this?
As #ADyson suggested, I wrote this code below:
const DIRETORIO_SEI = 'sei';
private static $caminho;
public static function getCaminhoModulo($append = '') {
if (self::$caminho != null) {
return self::$caminho;
}
$diretorio = explode('/', realpath(__DIR__.'/../../../'));
$caminho = '';
$incluir = false;
for ($i = 0; $i < count($diretorio); $i++) {
if ($incluir) {
$caminho = $caminho . $diretorio[$i] . '/';
}
if ($diretorio[$i] == self::DIRETORIO_SEI) {
$incluir = true;
}
}
self::$caminho = $caminho;
return $caminho.$append;
}

Codeigniter delete the directory and its contents

I am trying to make codeigniter delete a product image folder.
Furthermore, the delete function I am trying to make needs to delete also all of its contents, so empty or not, the folder gets deleted. I'm guessing, it would use a recursive type of deletion...I'm not so sure at all.
I have tried the below functions for deleting :
function delete_directory($path)
{
$path=base_url().'products/thumb/';
$this->load->helper("file"); // load the helper
delete_files($path, true); // delete all files/folders
//rmdir($dirname);
if(rmdir($path)){
echo 'deleted';die;}
else{
echo 'not';die; }
return true;
}
But it always returning not
Deleting directory content:
It will probably work, I have used
$this->load->helper('directory');
$this->load->helper("file");
$dir_fiels = directory_map('resources/captcha/');
$len = sizeOf($dir_fiels);
for($i=0; $i<$len;$i++){
unlink('resources/captcha/'.$dir_fiels[$i]);
}
create an helper. see below:-
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
if ( ! function_exists('remove_directory'))
{
function remove_directory($directory, $empty=FALSE)
{
if(substr($directory,-1) == '/') {
$directory = substr($directory,0,-1);
}
if(!file_exists($directory) || !is_dir($directory)) {
return FALSE;
} elseif(!is_readable($directory)) {
return FALSE;
} else {
$handle = opendir($directory);
while (FALSE !== ($item = readdir($handle)))
{
if($item != '.' && $item != '..') {
$path = $directory.'/'.$item;
if(is_dir($path)) {
remove_directory($path);
}else{
unlink($path);
}
}
}
closedir($handle);
if($empty == FALSE)
{
if(!rmdir($directory))
{
return FALSE;
}
}
return TRUE;
}
}
}
then load this helper in Your controller and call function remove_directory()
/* End of file recursive_helper.php */
/* Location: /application/helpers/recursive_helper.php */
Delete all files:
delete_files('./path/to/your/directory/');
Include sub-folder(s):
delete_files('./path/to/your/directory/', TRUE);

Joomla, php GET and redirecting

I have joomla 2.5 site, and I have
http://www.something.com/places?x=target
I would like to have URL like this:
http://www.something.com/places/target
How can I do this?
EDIT:
on .htaccess following works:
RewriteRule ^places/(.*)$ http://www.something.com/places?x=$1 [L,P,nc]
However it does not work with spaces ('/places/tar get' will only go to '/places?x=tar'). How can I fix that?
EDIT 2:
RewriteRule ^places/([^\ ])\ (.)$ http://www.something.com/places?x=$1\%20$2 [L,P,nc]
RewriteRule ^places/(.*)$ http://www.something.com/places?x=$1 [L,P,nc]
doest the trick. Thank you all!
If the places page belongs to a custom component (not a Joomla! built-in component), you will need to write or adjust the router.php file, in the component's directory.
It will need to contain something like:
function yourcomponentnameBuildRoute(&$query) {
$segments = array();
if (isset($query["x"])) {
$segments[] = $query["x"];
unset($query["x"]);
}
return $segments;
}
function yourcomponentnameParseRoute($segments) {
$vars = array();
$count = count($segments);
switch($segments[0]) {
case "target":
$vars["x"] = "target";
break;
}
return $vars;
}
UPDATE for your specific case:
Unfortunately there is no way to do this without a core hack.
So backup your *components/com_content/router.php* file, and then edit it as follows:
Replace the following code (around line 132):
if ($view == 'article') {
if ($advanced) {
list($tmp, $id) = explode(':', $query['id'], 2);
}
else {
$id = $query['id'];
}
$segments[] = $id;
}
unset($query['id']);
unset($query['catid']);
with this:
if ($view == 'article') {
if ($advanced) {
list($tmp, $id) = explode(':', $query['id'], 2);
}
else {
$id = $query['id'];
}
if(isset($query['x']) && $query['x']) {
$segments[] = $query['x'];
}
$segments[] = $id;
}
unset($query['x']);
unset($query['id']);
unset($query['catid']);
and this code (around line 212):
if (!isset($item)) {
$vars['view'] = $segments[0];
$vars['id'] = $segments[$count - 1];
return $vars;
}
// if there is only one segment, then it points to either an article or a category
// we test it first to see if it is a category. If the id and alias match a category
// then we assume it is a category. If they don't we assume it is an article
if ($count == 1) {
// we check to see if an alias is given. If not, we assume it is an article
if (strpos($segments[0], ':') === false) {
$vars['view'] = 'article';
$vars['id'] = (int)$segments[0];
return $vars;
}
with this:
if (!isset($item)) {
$vars['view'] = $segments[0];
$vars['id'] = $segments[$count - 1];
$vars['x'] = $count >= 2 ? $segments[$count - 2] : NULL;
return $vars;
}
// if there is only one segment, then it points to either an article or a category
// we test it first to see if it is a category. If the id and alias match a category
// then we assume it is a category. If they don't we assume it is an article
if ($count == 1 || ($count == 2 && (int) $segments[0] === 0)) {
// we check to see if an alias is given. If not, we assume it is an article
if (strpos($segments[0], ':') === false) {
$vars['view'] = 'article';
$vars['x'] = $count == 2 ? $segments[$count - 2] : NULL;
$vars['id'] = (int)$segments[$count - 1];
return $vars;
}
Then in your article's PHP code, you would use:
$target = JRequest::getVar("x");
I haven't tested it, so I'm not sure if it works. Let me know.

PHP recursive delete function

I wrote recursive PHP function for folder deletion. I wonder, how do I modify this function to delete all files and folders in webhosting, excluding given array of files and folder names (for ex. cgi-bin, .htaccess)?
BTW
to use this function to totally remove a directory calling like this
recursive_remove_directory('path/to/directory/to/delete');
to use this function to empty a directory calling like this:
recursive_remove_directory('path/to/full_directory',TRUE);
Now the function is
function recursive_remove_directory($directory, $empty=FALSE)
{
// if the path has a slash at the end we remove it here
if(substr($directory,-1) == '/')
{
$directory = substr($directory,0,-1);
}
// if the path is not valid or is not a directory ...
if(!file_exists($directory) || !is_dir($directory))
{
// ... we return false and exit the function
return FALSE;
// ... if the path is not readable
}elseif(!is_readable($directory))
{
// ... we return false and exit the function
return FALSE;
// ... else if the path is readable
}else{
// we open the directory
$handle = opendir($directory);
// and scan through the items inside
while (FALSE !== ($item = readdir($handle)))
{
// if the filepointer is not the current directory
// or the parent directory
if($item != '.' && $item != '..')
{
// we build the new path to delete
$path = $directory.'/'.$item;
// if the new path is a directory
if(is_dir($path))
{
// we call this function with the new path
recursive_remove_directory($path);
// if the new path is a file
}else{
// we remove the file
unlink($path);
}
}
}
// close the directory
closedir($handle);
// if the option to empty is not set to true
if($empty == FALSE)
{
// try to delete the now empty directory
if(!rmdir($directory))
{
// return false if not possible
return FALSE;
}
}
// return success
return TRUE;
}
}
Try something like this:
$it = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator('%yourBaseDir%'),
RecursiveIteratorIterator::CHILD_FIRST
);
$excludeDirsNames = array();
$excludeFileNames = array('.htaccess');
foreach($it as $entry) {
if ($entry->isDir()) {
if (!in_array($entry->getBasename(), $excludeDirsNames)) {
try {
rmdir($entry->getPathname());
}
catch (Exception $ex) {
// dir not empty
}
}
}
elseif (!in_array($entry->getFileName(), $excludeFileNames)) {
unlink($entry->getPathname());
}
}
I'm using this function to delete the folder with all files and subfolders:
function removedir($dir) {
if (substr($dir, strlen($dir) - 1, 1) != '/')
$dir .= '/';
if ($handle = opendir($dir)) {
while ($obj = readdir($handle)) {
if ($obj != '.' && $obj != '..') {
if (is_dir($dir . $obj)) {
if (!removedir($dir . $obj))
return false;
}
else if (is_file($dir . $obj)) {
if (!unlink($dir . $obj))
return false;
}
}
}
closedir($handle);
if (!#rmdir($dir))
return false;
return true;
}
return false;
}
$folder_to_delete = "folder"; // folder to be deleted
echo removedir($folder_to_delete) ? 'done' : 'not done';
Iirc I got this from php.net
You could provide an extra array parameter $exclusions to recursive_remove_directory(), but you'll have to pass this parameter every time recursively.
Make $exclusions global. This way it can be accessed in every level of recursion.

Convert URI to URL

How to convert an URI to URL if I know the current site path?
Consider these examples:
Current path is: `http://www.site.com/aa/folder/page1.php
Uri: folder2/page.php
Uri: /folder2/page.php
And what if the current path is:
`http://www.site.com/aa/folder/
or
`http://www.site.com/aa/folder
What the URLs will look like then?
I know this should be easy and obvious, but I can't find anywhere the complete answer (and yes, I did searched on Google)
Here is a block of code that has the function that you need:
http://ca.php.net/manual/en/function.parse-url.php#76682
Edit: The above linked function modified with an example
<?php
var_dump(resolve_url('http://www.site.com/aa/folder/page1.php','folder2/page.php?x=y&z=a'));
var_dump(resolve_url('http://www.site.com/aa/folder/page1.php','/folder2/page2.php'));
function unparse_url($components) {
return $components['scheme'].'://'.$components['host'].$components['path'];
}
/**
* Resolve a URL relative to a base path. This happens to work with POSIX
* filenames as well. This is based on RFC 2396 section 5.2.
*/
function resolve_url($base, $url) {
if (!strlen($base)) return $url;
// Step 2
if (!strlen($url)) return $base;
// Step 3
if (preg_match('!^[a-z]+:!i', $url)) return $url;
$base = parse_url($base);
if ($url{0} == "#") {
// Step 2 (fragment)
$base['fragment'] = substr($url, 1);
return unparse_url($base);
}
unset($base['fragment']);
unset($base['query']);
if (substr($url, 0, 2) == "//") {
// Step 4
return unparse_url(array(
'scheme'=>$base['scheme'],
'path'=>$url,
));
} else if ($url{0} == "/") {
// Step 5
$base['path'] = $url;
} else {
// Step 6
$path = explode('/', $base['path']);
$url_path = explode('/', $url);
// Step 6a: drop file from base
array_pop($path);
// Step 6b, 6c, 6e: append url while removing "." and ".." from
// the directory portion
$end = array_pop($url_path);
foreach ($url_path as $segment) {
if ($segment == '.') {
// skip
} else if ($segment == '..' && $path && $path[sizeof($path)-1] != '..') {
array_pop($path);
} else {
$path[] = $segment;
}
}
// Step 6d, 6f: remove "." and ".." from file portion
if ($end == '.') {
$path[] = '';
} else if ($end == '..' && $path && $path[sizeof($path)-1] != '..') {
$path[sizeof($path)-1] = '';
} else {
$path[] = $end;
}
// Step 6h
$base['path'] = join('/', $path);
}
// Step 7
return unparse_url($base);
}
?>
The $_SERVER superglobal will have the information you're looking for, namely $_SERVER['REQUEST_URI'] and $_SERVER['SERVER_NAME']. $_SERVER['QUERY_STRING'] might also be useful.
Please see:
http://php.net/manual/en/reserved.variables.server.php
php has pathinfo(), realpath() and parseurl() and other filesystem and url path functions. Used together with info from the $_SERVER superglobal (as mentioned by andre), you should be able to do what you need.
$uri = "http://www.site.com/aa/folder/";
$url = explode("/", $uri);
$url = $url[2];
echo $url; //www.site.com
Is this what you are looking for?
If you install PECL pecl_http, you can make use of http_build_url:
http_build_url("http://www.site.com/aa/folder/page1.php",
array("path" => "folder2/page.php"));
and you pass any of your relative URI(L)s as path. The function will make sure to build the correct one.
