What should I use: _Get / _Post / _Request...etc.

Hello everyone.

I have a form that includes a 'File' attachment.

The webhost has upgraded to PHP4 so I have to use the Global Vars thinggy....

Say I have <input name="Name" type="text">, to get that var on the next page, do I use $_post['name'] ?

Is it the same thing with a File type?

Cheers for your help, this is really bugging me.

If your form uses method="post", you should use the $POST array.
Otherwise, you should use $GET

For files, use $_FILES

Read the PHP Manual appendix on reserved words for more info.

Cheers for the help....

I've been trying out a test doing the following...


echo "Post =".$_post['test']."<BR>";
echo "Get =".$_get['test']."<BR>";
echo "Request =".$_request['test']."<BR>";
echo "Normal =".$test."<BR>";
echo " 
<form action=\"".$_SERVER['PHP_SELF']."\" method=\"post\" ENCTYPE=\"multipart/form-data\">
<input name=\"test\" value=\"Testing..123\">
 <input type=\"submit\" name=\"Submit\" value=\"Submit\">
</form>";

And the only one that seems to work is 'normal'.

Any ideas?

echo "Post =" . $_POST['test'] . "<BR>";
echo "Get =" . $_GET['test'] . "<BR>";
echo "Request =" . $_REQUEST['test'] . "<BR>";
echo "Normal =" . $test . "<BR>";
echo "
<form action=\"" . $_SERVER['PHP_SELF'] . "\" method=\"post\" ENCTYPE=\"multipart/form-data\">
<input name=\"test\" value=\"Testing..123\">
<input type=\"submit\" name=\"Submit\" value=\"Submit\">
</form>";

If $test works, it means that register_globals is on.

The main thing is that the client wants for the script to work before AND afterwards.

Can I do the following so it works after the migration?


if (! $test) {$test = $_POST['test'];}

echo "Post =" . $_POST['test'] . "<BR>"; 
echo "Get =" . $_GET['test'] . "<BR>"; 
echo "Request =" . $_REQUEST['test'] . "<BR>"; 
echo "Normal =" . $test . "<BR>"; 
echo " 
<form action=\"" . $_SERVER['PHP_SELF'] . "\" method=\"post\" ENCTYPE=\"multipart/form-data\"> 
<input name=\"test\" value=\"Testing..123\"> 
<input type=\"submit\" name=\"Submit\" value=\"Submit\"> 
</form>";

What do you mean by "before and afterwards"?

Just use the $_POST['test'], unless there is a high probability of having to work on an old system, e.g. PHP 4.0.6

You may want to check with [man]isset/man or [man]empty/man first though, or warnings may be reported by PHP.

Before would be before the global vars are turned on
After would be when the Global Vars are turned off.

How could I make it work before AND after ?

$_POST and other superglobals work whether register_globals is on or off, as long as the PHP version isnt too old.

Thanks.

I think the version is old though, probaly 3.

Can I use the

if (! isset($test)) {$test = $_POST['test'] }

Rather than go through the whole script changing every var?

I am not familiar with PHP3.

Must you continue to support PHP3?

You may have to use the old $HTTP*VARS style, which is not superglobal, so requires a:
global $HTTP_POST_VARS;
within functions, for example.

Or you can just keep register_globals on.
You cant decide to code with register_globals off and use superglobals, and at the same time be backward compatible with PHP3.

You can code with register_globals on, or choose to use the deprecated $HTTP*VARS form with the global keyword, but I wont enthusiastically recommend either.
