how to add all $_get vars into url

djpirra

Hi guys...

sometime ago i used a way to complete an url with the remaining $_get[] vars....

At the current time i have forgotten how to do that...

So if anyone can remind me that function please go ahead 😉

i wanted to do something like this...[url]http://www.....com/?id=1&...remaining[/url] $_get[]

😃 Best Regards

So you want to turn:

array(
  'id'=>1,
  'a'=>'a value',
  'b'=>'b value'
)

into: file.php?id=1&a=a%20value&b=b%20value

Try something like:

$string = '?';
foreach ($array as $key=>$value) {
  $string .= '&' . $key . '=' . urlencode($value);
}

Hope that helps.

I thought there was a function that spit all the $get content into the url...

If my code didn't help, then please explain the problem in more detail. Please note that $_GET is used for getting the info out, not for setting it, but you're talking like you want to set information.

No i don't want to set the $_get...
Your function was correct but i think there is a better way of doing it...

i think it was using: $_SERVER['query_string']

Are you BUILDING a query string, or are you PARSING a query string?

i want this:

i had the url: www.xxxxx.com/index.php?a=2&b=4

and then when i click a button that changes the "a" to 3 i want to keep the b=4 in the url so it becames:

www.xxxxx.com/index.php?a=3&b=4

right?

😉

There is nothing that says you can't redefine the a value in the $_GET array and then create your link... See if something like this works for you.

$_GET['a'] = ($_GET['a']+1);

$qryurl = "";
foreach($_GET AS $k => $v){
  $qryurl .= $k."=".$v."&";
}
$stringlength = strlen($qryurl);
$qryurl = substr($qryurl, 0, ($stringlength-1));

echo "<a href=\"link.php?".$qryurl."\">Click Me</a>";

In any respect, you always want to build in error checking to check for the existence of desired variables... That way if someone tried to injec t into your script, you could unset rogue variables so they don't get mixed up in your output links... You probably also want to check the referring source just in case injected variables are named the same as yours...
