URL Parameters Manipulation 1

[Extension]

Hi,

I trying to come up with an easy solution to change a specific parameter in the URL.
Example of URL format:

[URL unfurl="true"]http://www.domain.com/dir/script.php?id=343&view=y&lang=russian[/URL]

I want to be able to change the "lang" parameter.
FYI: The lang param is not always last in the URL.
I guess this could be handled with a Regex ?

$NEW_LANG = 'english';

$URL_STRING = $_SERVER['QUERY_STRING'];

... Regex to change lang value by $NEW_LANG ... 

$NEW_URL_STRING = $_SERVER['SCRIPT_NAME'] . "?" . $URL_STRING;

A weird sense of Dejavu....

$URL_STRING = str_replace('russian','english',$_SERVER['QUERY_STRING']);

No it's different this time.

The lang (language) in the URL is not always russian; close to 22 possibilities so a straight str_replace won't work.

If you mean to change multiple language tags to a single language description ("russian" and "german" and "french" will all go to "english") then a str_replace() with array input parameters likely will. See the second example on the PHP online manual page for str_replace()

It could be

[URL unfurl="true"]http://www.domain.com/dir/script.php?id=343&view=y&lang=russian[/URL]

or

[URL unfurl="true"]http://www.domain.com/dir/script.php?id=343&view=y&lang=swedish[/URL]

etc..

I simply need a solution to change the lang value for another one.

 

[sleipnir214]

Again, if you are changing any of a specific set of languages to "english", look at the second code example on the PHP online manual page for str_replace().

If you are trying to replace any language string in the URL:

[tt][ignore]

http://www.domain.com/dir/script.php?id=343&view=y&lang=qwertyuiop

[/ignore][/tt]

to english:

[tt][ignore]

http://www.domain.com/dir/script.php?id=343&view=y&lang=english

[/ignore][/tt]

Then you might have to resort to a regular expression.

Yes, this is what I'm trying to achieve. As you said, I guess a Regex will be the solution ?

 

[sleipnir214]

If you are saying "yes" to the second scenario in my last post, yes, you are going to need a regular expression.

As I see it, there are only two cases you have to worry about, the case where the "lang" attribute is at the beginning of the sting of values and when it is not.

Play with this:

<?php
//$a = '[URL unfurl="true"]http://www.domain.com/dir/script.php?id=343&view=y&lang=swedish';[/URL]
//$a = '[URL unfurl="true"]http://www.domain.com/dir/script.php?lang=swedish&id=343&view=y';[/URL]
$a = '[URL unfurl="true"]http://www.domain.com/dir/script.php?id=343&lang=swedish&view=y';[/URL]
print preg_replace ('@([\?&])lang=[^\?&]*@', '$1lang=english', $a);

?>
