Extracting a web address to a variable

[unistake]

Morning all,

 

I am wondering whether there is a way (I am sure there is!) to extract the full website address with any GET variables in it also.

 

Basically, I am trying to extract the website address and add another $_GET['var'] to it.

 

Something like.

 

example web address:  http://www.website.com/index.php?type=abc

<?php
$address = // Extract the current website address here.
$newvar = "?model=123";
$link = $address.$newvar;

echo '<a href="$link">Click here to add a variable</a>';
?>

You can use _SERVER["QUERY_STRING"] for just the get vars and values, or _SERVER["REQUEST_URI"] to get the filename with vars and values attached

I posted an URL extractor script earlier today... here's the thread:

<?php
$newvar = mysql_real_escape_string($_GET['newvar']);
$home_url = "http://".$_SERVER['HTTP_HOST'];
$url = "http://".$_SERVER['HTTP_HOST'].$_SERVER['SCRIPT_NAME'];

if (!empty($_SERVER["QUERY_STRING"])){
$url .= "?".$_SERVER['QUERY_STRING'];
}
if ($url == "$home_url") {
$url = "$url?$newvar";
}
echo "<a href='$home_url'>Home</a><br />";
echo "<a href='$url'>$url</a><br />";

?>
<form name="input" action="<?php echo $url; ?>" method="get">
New Variable:<input size="30"type="text" name="newvar" style="color: #FFFFFF; font-family: Verdana; font-weight: bold; font-size: 12px; background-color: #000000;" size="15" value="<?php echo $_GET['newvar']; ?>">
<input type="submit" style="color: #FFFFFF; font-family: Verdana; font-weight: bold; font-size: 12px; background-color: #000000;" size="15" value="Make New Variable" />
</form>
<?php
echo "Compliments of Quick";
?>

QOC,

 

Thanks a lot for that - looks neat. I'll add that one to my script collection!

You are welome.

 

I used this method in creating a paginated full search/navigation system with multiple selects for mysql.

 

Converting the count to page numbers and a whole lot of math and determining mysqls start row for the selects. Then set max pages to those values.

 

I'd post the code but is so complex would not be usable unless under real circumstances will all the correct parameters set.

yeah please don't bombard me with maths!
