$GET['my.foo']

[MadTechie]

ok a simple question i hope

 

i need to pass a get string but the variable requires a dot (.) but php converts this to a underscore (_) this normally wouldn't be a problem but some variables use the underscore

 

heres some basic code

 

url = index.php?my.foo=hello&my_foo2=world

<?php

print "my.foo:".$_GET['my.foo']."<br />";
print "my_foo:".$_GET['my_foo']."<br />";
print "my_foo2:".$_GET['my_foo2']."<br />";

print_r($_GET);

?>

 

any ideas how to resolve this, as a note the variable names are pulled in from a data file created by the user

Are you able to encode the variable name as well as its value?  For example

 

$varname = 'my.foo';
$varval = 'hello';
$encoded = urlencode("$varname=$varval");
$url = "index.php?var=$encoded";

[MadTechie]

true, i'll see if i can add it into my code

 

Thanx btherl

[MadTechie]

urlencode doesn't solve the dot (.) problem, anyone have another idea ?

Can you change the variables passed by the URL to use arrays? If you can you can then say:

url = index.php?my.foo[]=hello&my_foo[]=world

and your script would then see both values in the array $_GET['my_foo']

Problem is only the my_foo[] would be returned.. when i'll be expecting my.foo[]

[kenrbnsn]

Here is one way around the problem, but to use it you will have to change some of your logic.

 

Make the URL look like this:

url = index.php?p[my.foo]=1&p[my_foo]=2

then you could use $_GET['p']['my.foo'] and $_GET['p']['my_foo']

lol, love it thats one way

 

i'll have a play see how deep my hole currently is (not sure how much needs updating)

 

thanx kenrbnsn
