Need urlencode help

[spinman]

Hi,

 

As a relative newbie, I am trying to create a link on one page to another page on my site using urlencode to encode the URL (together with a little javascript onclick code).  The problem I have is that when I run the code using urlencode(), I get a 403 permission denied error. If I run the same thing without urlencode it works find.

 

I tried this both on my locally installed wamp setup as well as on my hosted site. The code (which I have simplified as much as possible for this question) is:

 

<?php

//This is the "go_from.php" page 
// Run this and then click one of the buttons

$url=urlencode("go_to.php?var=1");
$url1="go_to.php?var=1";

$text .=
"<form method='get'>
<div><input type='button' value='Select the Go To Page WITH encoded URL'  onclick=\"javascript:window.location='$url';\"></div>
<div><input type='button' value='Select the Go To Page WITHOUT encoded URL'  onclick=\"javascript:window.location='$url1';\"></div>
</form>";

echo $text;
?>

 

...and it is calling this page:

 

<?php
//this is the "go_to.php" page which is called by "go_from.php"

echo "This is the go to page";
echo $_GET['var'];

?>

 

Any ideas as to why the top button errors out?

 

Thanks in advance,

 

Dennis

 

 

PS: Correction - I used GET (not POST)

The "?" in a URL should not be url encoded.  The parts to encode are the values of each get variable.  In your case, you would encode the value "1" (which just encodes to itself).

 

But if you wanted to set "var=&" for example, you would need to urlencode the "&"

Thanks for clearing that up for me!

 

So if I understand you correctly, if I needed to build an encoded URL which passes multiple variables, I would do something like:

<?php
$url="go_to.php?var1=" . urlencode($var1) .
             "&var2=" . urlencode($var2) .
             "&var3=" . urlencode($var3);
?>

 

This works fine, I was just hoping for an easier way to convert a url in one go, but thanks in any case!

Yep, that's basically it.  I don't know of any simple way to do that encoding.

 

About the &, you may not need that if you are setting the url using window.location.  I'm not sure about that.  The whole thing about when you need & kinda confuses me actually   If it doesn't work, try it as just plain "&"
