change all href of external page after insert it

Question

I have inserted external content to my page using simple_html_dom.php but all href not working for example :

 href='oldpage.php'

and I want this like to be changed to

href='http://localhost/oldpage.php'

or

href='http://localhost/mynewpage.php'

is there a way to change all href to new one like add some string before it ? Thank you

so, why not take care of it during the same time you executed the other script? sounds to me like it would be simpler. — Funk Forty Niner, Dec 22 '15 at 02:32

@Fred-ii- the script can bring all the html text . I want to update all href to new link like add additional text in-front of it ! — Maadh, Dec 22 '15 at 02:35
did you have a look at the link that Sam left you above? (looks like a duplicate) since you did tag as javascript/jquery. — Funk Forty Niner, Dec 22 '15 at 02:35
@Fred-ii- Yes , but I did not understand it . I need something similar to @ rahul answer but in PHP . like one command or loop to change all href . Thank you — Maadh, Dec 22 '15 at 02:40
so why did you add the javascript/jquery tags? you need to remove those if you're wanting a PHP solution, since that implies that you're looking for those methods. You'll need to edit your question in order to let visitors to the question know of what you want/need here. — Funk Forty Niner, Dec 22 '15 at 02:42
@Fred-ii- can I use this javascript code inside the PHP and then use the result in PHP ? — Maadh, Dec 22 '15 at 02:44
see this Q&A then for PHP http://stackoverflow.com/q/6240414/ could be something in there you can use. — Funk Forty Niner, Dec 22 '15 at 02:44
Simple solution that could cause issues, `str_replace('href="', 'href="http://www.example.com/', $string);` or use domdocument and pull all href attributes. — chris85, Dec 22 '15 at 02:44
@chris85 ^^^ Let's only hope somebody doesn't come along and sweep the rug from under your feet ;-) — Funk Forty Niner, Dec 22 '15 at 02:46
@chris85 Thank you very much , your answer solved the problem. But I don't know why my question get vote down ! — Maadh, Dec 25 '15 at 20:04

You can use .each() to iterate your anchor tags. Then using .attr you should be able to get the href attribute value.

Then a string append using + should do the work. So something like the below one should work

$("a.links").each(function(){
    var $this = $(this);
    var currentHref = $this.attr("href");
    var modifiedHref = "your string" + currentHref;

    $this.attr("href", modifiedHref);
});

You could do a simple string replace like:

str_replace('href="', 'href="http://www.example.com/', $string);

or with domdocument:

$page = '<html><head></head><body><a href="simple"></a><h1>Hi</h1><a href="simple2"></a></body></html>';
$doc = new DOMDocument();
$doc->loadHTML($page);
$as = $doc->getElementsByTagName('a');
foreach($as as $a){
    $a->setAttribute('href', 'http://www.example.com/' . $a->getAttribute('href'));
}
print_r($doc->saveHTML());

output:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html><head></head><body><a href="http://www.example.com/simple"></a><h1>Hi</h1><a href="http://www.example.com/simple2"></a></body></html>

This doesn't take into account absolute paths, you'll need a regex approach for that..

If the quote types vary you also will need to use a regex for the str_replace example. Can do something like('|") for that then use $1 to match the quote type.

You only need to add

<base href="http://localhost/"></base>

Inside head section. its create base url for all other anchor tag. will converted Url as you want.

It will work for you. Try it.

here is a pure javascript approach using replace

//replace selector 'a' with your css selector if needed
for(var i=0;i<document.querySelectorAll('a').length;++i){
var new_href=document.querySelectorAll('a')[i].getAttribute('href').replace(/(http:[/]{2}localhost)[/].*/ig, '$1/mynewpage.php')
document.querySelectorAll('a')[i].setAttribute('href',new_href)
}
//

Just append "/" before your url like

href='oldpage.php' => href='/oldpage.php'
