PHP_SELF med GET?

Hej

Du kan bare tilføje endnu flere variabler til urlen

side.php?farve=2&id=123&alder=56

mvh gf

og hvis du vil hente id i urlen

<a href="index.php?id=<?=$_GET[id]?>"> tekst    </a>

Et lille eksempel:

<?php

  echo "a=" . $_GET[a] . ", b=" . $_GET[b] . ", c=" . $_GET[c] . "<br><br>";

  echo "<a href=\"" . $_SERVER[PHP_SELF] . "?a=" . 1 . "&amp;b=" . $_GET[b] . "&amp;c=" . $_GET[c] . "\">set a=1</a><br>";
  echo "<a href=\"" . $_SERVER[PHP_SELF] . "?a=" . 0 . "&amp;b=" . $_GET[b] . "&amp;c=" . $_GET[c] . "\">set a=0</a><br>";
  echo "<a href=\"" . $_SERVER[PHP_SELF] . "?a=" . $_GET[a] . "&amp;b=" . 1 . "&amp;c=" . $_GET[c] . "\">set b=1</a><br>";
  echo "<a href=\"" . $_SERVER[PHP_SELF] . "?a=" . $_GET[a] . "&amp;b=" . 0 . "&amp;c=" . $_GET[c] . "\">set b=0</a><br>";
  echo "<a href=\"" . $_SERVER[PHP_SELF] . "?a=" . $_GET[a] . "&amp;b=" . $_GET[b] . "&amp;c=" . 1 . "\">set a=1</a><br>";
  echo "<a href=\"" . $_SERVER[PHP_SELF] . "?a=" . $_GET[a] . "&amp;b=" . $_GET[b] . "&amp;c=" . 0 . "\">set a=1</a><br>";
  echo "<a href=\"" . $_SERVER[PHP_SELF] . "?a=" . 42 . "&amp;b=" . 42 . "&amp;c=" . 42 . "\">set a=b=c=42</a><br>";

?>

Måske er det nærmere _SERVER["REQUEST_URI"] eller _SERVER["QUERY_STRING"]

I ekspemplet "index.php?id=234&farve=2" vil de give følgende resultater:

_SERVER["QUERY_STRING"] = id=234&farve=2
_SERVER["REQUEST_URI"] = /index.php?id=234&farve=2
