I need help with converting HREF link to lowercase and dashes

[belick]

I want to look for anywhere in the page that there is links and if there is a link with spaces like below then to convert it to:

 

1. Lowercase

2. spaces = deshes

3. add .html at the end

 

href="Search Engine Optimization"

will be:

href="search-engine-optimization.html"

 

is it possible?

[ldougherty]

Hope this helps..

 

<?php

 

$string = 'href="Search Engine Optimization"';

echo "String Before: $string<br><br>";

 

$string = strtolower($string);

 

$pattern = '/ /';

$replacement = '-';

 

$string = preg_replace($pattern, $replacement, $string);

 

$string = substr_replace($string,'.html"',-1);

 

echo "String After: $string<br>";

 

?>

For upper to lower case:

toLowerCase()

 

For space to dash:

var.replace(' ', '-');

 

To add .html to end:

var=var+'.html';

Thanks, but the problem is that the preg need to look for any string and not for specific one...

If you use jquery you could do something along the lines of this (untested):

 

$("a").each(function(){
    $(this).attr('href', $(this).attr('href').toLowerCaser().replace(' ', '-')+'.html');
})

 

Again it's untested and just an idea out of my head, but I think it should work or at least be close.  Can anyone confirm this?  I am unable to test right now.

I was looking for smthing like this:

 

echo preg_replace('~href="([^"])+"~', 'href="'.strtolower("$1").'"', $WebPage);

 

but the strtolower("$1") is not working... also I want to look for anything without the html

 

the idea is to look for any link like: Home Page, About Us and such and convert it to lowercase without spaces... and then to add .html

Use preg_replace_callback.

 

For example:

 

function link_replace_callback($matches)
{
  $linkUrl = str_replace(" ","-",strtolower($matches[0]));
  return 'href="'.$linkUrl.'"';
}
echo preg_replace_callback(
            '~href="([^"])+"~',
            "link_replace_callback",
            $WebPage);

 

 

You could probably also use the callback function to leave intact anything with .html in it.

[belick]

yes, thanks but 1 issue... I tried to add more text to return $linkUrl; and it always bring the extra text after the quotes:

 

function link_replace_callback($matches) {

  $linkUrl = str_replace(" ","-",strtolower($matches[0]));

  return $linkUrl.".html";

}

echo preg_replace_callback('~href="([^"])+"~', "link_replace_callback", $WebPage);

 

and on my links I get:

 

<a href="test-trest".html</a>

Sorry, should have used $matches[1].

 

The regexp also needed slight modification, and I've added code to leave hrefs ending in .html intact.

 

function link_replace_callback($matches)
{
if (substr($matches[1],-5)==".html") return 'href="'.$matches[1].'"';
$linkUrl = str_replace(" ","-",strtolower($matches[1]));
return 'href="'.$linkUrl.'.html"';
}
echo preg_replace_callback('~href="([^"]+)"~',"link_replace_callback",$WebPage);

 

(I've actually tested my code this time!)
