SEO Slug (PHP preg_replace equivalent)

I need to create a SEO slug from a bit of text - Currently, I use the following PHP code but need some guidance on converting it to Livecode:
Code: Select all
<?php
function create_seo_slug($string, $ext='.html'){
$replace = '-';
$string = strtolower($string);
//replace / and . with white space
$string = preg_replace("/[\/\.]/", " ", $string);
$string = preg_replace("/[^a-z0-9_\s-]/", "", $string);
//remove multiple dashes or whitespaces
$string = preg_replace("/[\s-]+/", " ", $string);
//convert whitespaces and underscore to $replace
$string = preg_replace("/[\s_]/", $replace, $string);
//limit the slug size
$string = substr($string, 0, 100);
//slug is generated
// if extension is specified, return string plus extension else return string.
return ($ext) ? $string.$ext : $string;
}
//INPUT
$string = "what is your name ?";
$slug = create_seo_slug($string);
//OUTPUT::
//what-is-your-name.html
?>
Does anyone have any guidance on how to easily make a livecode equivalent of the PHP preg_replace ? All I need to do duplicate the above code so that it runs in a livecode app and generates the same/correct seo slug url's.

Hi Thomas,
Here is a straight (and quick) translation but *NOT* tested.
Nice if you tell us if it works.
Code: Select all
function create_seo_slug T, theExtension
local theReplace = "-" // $replace = '-';
put toLower( T) into T
//replace / and . with white space
put replaceText( T, "[/.]", space) into T
// $string = preg_replace("/[^a-z0-9_\s-]/", "", $string);
put replaceText( T, "[^a-z0-9_\s-]", empty) into T
//remove multiple dashes or whitespaces [1]
put replaceText( T, "[\s-]+", space) into T
//convert whitespaces and underscore to $replace
put replaceText( T, "[\s_]", theReplace) into T
// limit the slug size
put char 1 to 100 of T into T
// if extension is specified, return string plus extension else return string.
if theExtension is empty then return T
return T & theExtension
end create_seo_slug

and if you like concise coding as I do,
here is a shorter one:
Code: Select all
function create_seo_slug_2 T, theExtension
return char 1 to 100 of \
replaceText( \
replaceText( \
replaceText( \
replaceText( \
toLower( T) , \
"[/.]", space), "[^\w\d_-\s]", empty) , "[\s-]+", space), "[\s_]", "-") \
& theExtension
end create_seo_slug_2
Regards,
Thierry

That works wonderfully. I didn't know replaceText could handle regex. Thanks so much - Wish I could hand you one in person, but this will have to do

Great.
And regex in LiveCode works pretty well (PCRE library)
Thanks for the beer, and for the second round, I'll offer you this one:
