I have this function above to create url slugs from posts title, the problem is that the ç characther is not being converted to c. It is actually being override by the function.
Example post title: Coração de Pelúcia
The slug generated: coraao-de-pelucia
How can i fix this function to generate the slug like: coracao-de-pelucia
function generate_seo_link($input,$replace = '-',$remove_words = true,$words_array = array())
{
//make it lowercase, remove punctuation, remove multiple/leading/ending spaces
$return = trim(ereg_replace(' +',' ',preg_replace('/[^a-zA-Z0-9\s]/','',strtolower($input))));
//remove words, if not helpful to seo
//i like my defaults list in remove_words(), so I wont pass that array
if($remove_words) { $return = remove_words($return,$replace,$words_array); }
//convert the spaces to whatever the user wants
//usually a dash or underscore..
//...then return the value.
return str_replace(' ',$replace,$return);
}
You should use the iconv module and a function such as this one to do the conversion:
function url_safe($string){
$url = $string;
setlocale(LC_ALL, 'pt_BR'); // change to the one of your language
$url = iconv("UTF-8", "ASCII//TRANSLIT", $url);
$url = preg_replace('~[^\\pL0-9_]+~u', '-', $url);
$url = trim($url, "-");
$url = strtolower($url);
return $url;
}

Users can add texts. This texts can have links.
I'd like do add click to it.
The problem is, some links works like:
http://www.example.com
links that has no http will not work and will become:
http://mywebsite.com/www.example.com
any ideas how to solve it?
function toLink($titulo){
$url = '~(?:(https?)://([^\s<]+)|(www\.[^\s<]+?\.[^\s<]+))(?<![\.,:])~i';
$titulo = preg_replace($url, '$0', $titulo);
return $titulo;
}
Use preg_replace_callback instead and you can interrogate the match to see if you need to add the protocol.
function toLink($titulo) {
$url = '~(?:(https?)://([^\s<]+)|(www\.[^\s<]+?\.[^\s<]+))(?<![\.,:])~i';
$titulo = preg_replace_callback($url, function($matches) {
$url = $matches[0];
if (!preg_match('/^https?:\/\//', $url)) $url = 'http://'.$matches[0];
''.$url.'';
}, $titulo);
return $titulo;
}
I have a problem to resolve. The first url allow me to display information or not on the website. It work fine.
I identify Account&Edit for example and make action.
http://localhost/boutique/index.php?Account&Edit
$_SERVER['QUERY_STRING'] = Account&Edit
If I rewrite the url, the system does not work and Account&Edit become Account/Edit
http://localhost/boutique/index.php/Account/Edit
$_SERVER['QUERY_STRING'] = '';
How to resolve this element when this element Account&Edit change ?
$_SERVER['QUERY_STRING'] is empty is this case.
Thank you.
I make that to solve the problem.
public function getUrlwithoutSEFU() {
if (empty($_SERVER['QUERY_STRING'])) {
$url = $_SERVER['REQUEST_URI'];
$replace = str_replace('index.php', '', $url);
$replace = str_replace(CLICSHOPPING::getConfig('http_path'), '', $replace);
$replace = substr($replace, 1);
$replace = str_replace('/', '&', $replace);
$url_string = $replace;
} else {
$url_string = $_SERVER['QUERY_STRING'];
}
return $url_string;
}
Take a look at RFC3875: The Common Gateway Interface (CGI) Version 1.1
When you have no ? i nthe request URL, then there's no query string.
Looking at REQUEST_URI would make sense.
This is how request urls are split into environment vars:
# QUERY_STRING
# ↓↓↓↓↓↓↓↓↓↓↓↓
http://localhost/boutique/index.php?Account&Edit
Or the part after the (directly invoked) php script. (This may vary depending on SAPI or be impacted by rewrite rules).
# PATH_INFO
# ↓↓↓↓↓↓↓↓↓↓↓↓↓
http://localhost/boutique/index.php/Account/Edit
Or the full path:
# REQUEST_URI
# ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
http://localhost/boutique/index.php/Account/Edit
Notably you would have to split it up yourself then. Also may show up as REDIRECT_REQUEST_URI for example in the $_SERVER array with some setups.
Solution
public function getUrlwithoutSEFU() {
if (empty($_SERVER['QUERY_STRING'])) {
$url = $_SERVER['REQUEST_URI'];
$replace = str_replace('index.php', '', $url);
$replace = str_replace(CLICSHOPPING::getConfig('http_path'), '', $replace);
$replace = substr($replace, 1);
$replace = str_replace('/', '&', $replace);
$url_string = $replace;
} else {
$url_string = $_SERVER['QUERY_STRING'];
}
return $url_string;
}
I have the following link as a string in php:
$url = 'http://www.example.com/assets/images/temp/10.jpg';
I am trying to add the word BIG before the number so at the end I will have:
$url = 'http://www.example.com/assets/images/temp/big10.jpg';
I am currently accomplishing that by using explode on / then adding big to the last array. My only issue is that in the future, this link might have less / i.e.: http://www.example.com/assets/10.jpg. In this case, my explode statement will not work. Is there a better way to add the word big after the last occurance of /?
I also came up with this method:
$url = 'http://www.example.com/assets/images/temp/10.jpg';
$filename = substr(strrchr($url, "/"), 1); // returns 10.jpg
$newfilename = 'big'.substr(strrchr($url, "/"), 1); // returns big10.jpg
$newurl = str_replace($filename,$newfilename,$url); // replaces 10.jpg with big.jpg
According to description as mentioned into above question as a solution to it please try executing following code snippet .
<?php
$url = 'http://www.example.com/assets/images/temp/10.jpg';
$fileName = basename($url);
$newFileName = 'big' . $fileName;
$url = str_ireplace($fileName, $newFileName, $url);
echo $url;
?>
Explode will always work. However, if you want a neater way to do it you can do this:
$url = 'http://www.example.com/assets/images/temp/10.jpg';
$newurl = substr_replace($url, "big", strrpos($url, '/') + 1, 0);
This will give your expected result: http://www.example.com/assets/images/temp/big10.jpg
There are quite a few methods to accomplish what you're wanting.
To me the easiest would be to use pathinfo to extract the filename, and then append your prefix to the basename.
$prefix = 'big';
$url = 'http://www.example.com/assets/images/temp/10.jpg';
$pathinfo = pathinfo($url);
var_dump($pathinfo['dirname'] . '/' . $prefix . $pathinfo['basename']);
Result: https://3v4l.org/3MkIG
string(51) "http://www.example.com/assets/images/temp/big10.jpg"
Object oriented approach: https://3v4l.org/aF5lf
class FileNamePrefixer extends SplFileInfo
{
public function addPrefix($prefix)
{
return $this->getPathInfo() . '/' . $prefix . $this->getBaseName();
}
}
$url = 'http://www.example.com/assets/images/temp/10.jpg';
$fileInfo = new FileNamePrefixer($url);
var_dump($fileInfo->addPrefix('big'));
Another method is to use preg_replace to specify a pattern of words you want to replace.
$prefix = 'big';
$url = 'http://www.example.com/assets/images/temp/10.jpg';
$new_url = preg_replace('/([\w|\s|-]+)(\.\w+)$/', $prefix . '$1$2', $url);
var_dump($new_url);
The pattern ([\w|\s|-]+)(\.\w+)$ means; at the end of the string, look for a word (characters: a-z, A-Z, 0-9, _, space, and -), followed by a period, which is followed by another word and store them in variables $1 and $2.
Result: https://3v4l.org/6e8d7
string(51) "http://www.example.com/assets/images/temp/big10.jpg"
Note that if your URL will optionally contain fragments or a querystring, the preg_replace pattern above will not work. Instead you would need to account for them as optional like so:
$prefix = 'big';
$url = 'http://www.example.com/assets/images/temp/10.jpg?foo=bar&baz=foo#foobar';
$new_url = preg_replace('/([\w|\s|-]+)(\.\w+)(\?.+)?(#.+)?$/', $prefix . '$1$2$3$4', $url);
var_dump($new_url);
The pattern (\?.+)?(#.+)? means; optionally find ? followed by anything, and optionally find # followed by anything and store them in variables $3 and $4 with the original pattern.
Result: https://3v4l.org/uuYrO
string(74) "http://www.example.com/assets/images/temp/big10.jpg?foo=bar&baz=foo#foobar"
I am using a bit.ly shortener for my custom domain. It outputs http://shrt.dmn/abc123; however, I'd like it to just output shrt.dmn/abc123.
Here is my code.
//automatically create bit.ly url for wordpress widgets
function bitly()
{
//login information
$url = get_permalink(); //for wordpress permalink
$login = 'UserName'; //your bit.ly login
$apikey = 'API_KEY'; //add your bit.ly APIkey
$format = 'json'; //choose between json or xml
$version = '2.0.1';
//generate the URL
$bitly = 'http://api.bit.ly/shorten?version='.$version.'&longUrl='.urlencode($url).'&login='.$login.'&apiKey='.$apikey.'&format='.$format;
//fetch url
$response = file_get_contents($bitly);
//for json formating
if(strtolower($format) == 'json')
{
$json = #json_decode($response,true);
echo $json['results'][$url]['shortUrl'];
}
else //for xml formatting
{
$xml = simplexml_load_string($response);
echo 'http://bit.ly/'.$xml->results->nodeKeyVal->hash;
}
}
As long as it is supposed to be url and if there is http:// - then this solution is the simplest possible:
$url = str_replace('http://', '', $url);
Change your following line:
echo $json['results'][$url]['shortUrl'];
for this one:
echo substr( $json['results'][$url]['shortUrl'], 7);
You want to do a preg_replace.
$variable = preg_replace( '/http:\/\//', '', $variable ); (this is untested, so you might also need to escape the : character ).
you can also achieve the same effect with $variable = str_replace('http://', '', $variable )
http://domain.name/1-As Low As 10% Downpayment, Free Golf Membership!!!
The above url will report 400 bad request,
how to convert such title to user friendly good request?
You may want to use a "slug" instead. Rather than using the verbatim title as the URL, you strtolower() and replace all non-alphanumeric characters with hyphens, then remove duplicate hyphens. If you feel like extra credit, you can strip out stopwords, too.
So "1-As Low As 10% Downpayment, Free Golf Membership!!!" becomes:
as-low-as-10-downpayment-free-gold-membership
Something like this:
function sluggify($url)
{
# Prep string with some basic normalization
$url = strtolower($url);
$url = strip_tags($url);
$url = stripslashes($url);
$url = html_entity_decode($url);
# Remove quotes (can't, etc.)
$url = str_replace('\'', '', $url);
# Replace non-alpha numeric with hyphens
$match = '/[^a-z0-9]+/';
$replace = '-';
$url = preg_replace($match, $replace, $url);
$url = trim($url, '-');
return $url;
}
You could probably shorten it with longer regexps but it's pretty straightforward as-is. The bonus is that you can use the same function to validate the query parameter before you run a query on the database to match the title, so someone can't stick silly things into your database.
See the first answer here URL Friendly Username in PHP?:
function Slug($string)
{
return strtolower(trim(preg_replace('~[^0-9a-z]+~i', '-', html_entity_decode(preg_replace('~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i', '$1', htmlentities($string, ENT_QUOTES, 'UTF-8')), ENT_QUOTES, 'UTF-8')), '-'));
}
$user = 'Alix Axel';
echo Slug($user); // alix-axel
$user = 'Álix Ãxel';
echo Slug($user); // alix-axel
$user = 'Álix----_Ãxel!?!?';
echo Slug($user); // alix-axel
You can use urlencode or rawurlencode... for example Wikipedia do that. See this link:
http://en.wikipedia.org/wiki/Ichigo_100%25
that's the php encoding for % = %25
I just create a gist with a useful slug function:
https://gist.github.com/ninjagab/11244087
You can use it to convert title to seo friendly url.
<?php
class SanitizeUrl {
public static function slug($string, $space="-") {
$string = utf8_encode($string);
if (function_exists('iconv')) {
$string = iconv('UTF-8', 'ASCII//TRANSLIT', $string);
}
$string = preg_replace("/[^a-zA-Z0-9 \-]/", "", $string);
$string = trim(preg_replace("/\\s+/", " ", $string));
$string = strtolower($string);
$string = str_replace(" ", $space, $string);
return $string;
}
}
$title = 'Thi is a test string with some "strange" chars ò à ù...';
echo SanitizeUrl::slug($title);
//this will output:
//thi-is-a-test-string-with-some-strange-chars-o-a-u
You could use the rawurlencode() function
To simplify just full the list of the variable $change_to and $to_change
<?php
// Just full the array list to make replacement complete
// In this space will change to _, à to just a
$to_change = [
' ', 'à', 'à', 'â','é', 'è', 'ê', 'ç', 'ù', 'ô', 'ö' // and so on
];
$change_to = [
'_', 'a', 'a', 'a', 'e', 'e', 'e','c', 'u', 'o', 'o' // and so on
];
$texts = 'This is my slug in êlàb élaboré par';
$page_id = str_replace($to_change, $change_to, $texts);
