variables via url; JS to PHP

dgnorton

I've been trying for two days now to pass a variable from JavaScript
onload="document.location('http//script.php?var1=val1')"
to PHP
echo($var1);

I've found a bunch of information, but none of it a simple,
/concise/ way of doing this. I'm hoping someone will be able to help me.

Thanks,
dgnorton

you should be able to get to it with

echo $_GET['var1'];

and note there's no need for parenthises with echo

Here is an example:

<?
if( isset( $_GET['var1'] ) ){
	$output = $_GET['var1'];
	echo $output;
	echo "<br />";
}
?>
<html>
<head>
<title>JS to PHP EX</title>
<script type="text/javascript" language="JavaScript">
<!--  

	value = "w00t";

function pageLoader(){

	// the URL & Location methods refer to the current page				
	//document.URL('?var1=' + value);

	// Here is the older deprecated version
	 window.location.href('?var1=' + value);
}

-->
</script>
</head>
<body>

<input type="submit" name="submit" value=" JS to PHP" onClick="pageLoader()">

</body>
</html>

After a bit, I was able to use what you taught me to make my script work!

I love having new know-how to put in my tool box 🙂

Thanks again.

Use this, USE THIS! I swear its better rofl... Anyways...

$query = $QUERY_STRING;
$query_Array = explode("&", $query);
foreach ($query_Array as $i) {
$doubleItem = explode("=", $i);
$$doubleItem[0] = str_replace("%20", " ", $doubleItem[1]);
}

It assigns variables values... soooo

lets say you have: index.php?variable1=value1

It will assign $variable1 the value of "value1"... also it can do this...

index.php?variable1=value1&variable2=value2

So you can assign variable2 and variable 2... oh btw, you want to create spaces?

<a href="index.php?variable=I have spaces in here">Spaces</a>

When they click on the link the actual address will be: index.php?variable=I%20have%20spaces%20in%20here
But when it gets to the page, and you echo out "$variable" you will see it as just text with spaces like normal... the top code parses out all that... I'm still workin on a few more things but don't do so, Until needed. 🙂

The particulars:
xitami
php5+
NScape8+

I changed up to php 5x and none of my superGlobals work ($GET, $POST, etc).
I even turned register_globals = on as a desperate attempt!
I'm submitting this to the php script by typing it in the browser address bar and hitting enter.

My url string:
http://127.0.0.1/test1/child1.php?var1=david

My script:
<?PHP
if( isset( $GET['var1'] ) ){
$output = $GET['var1'];
echo $output;
echo "<br />";
}

     //just to make sure:
echo('<pre>');
print_r($_POST);
die();

If this is a syntax error, then I'm just stoo...stoo...stoo...stoo...stoopid! (born in a barn and all.... 😃 )

Bless you, in advance 🙂
