Array using php variables

[jroscoe]

I have a form that passes in a bunch of variables. On the results page, I am trying to create an array using these variables. Here is my code:

$streetaddress=trim($streetaddress);
$city=trim($city);
$state=trim($state);
$zip=trim($zip);

	$storenum=trim($storenum);
	$closestprox=trim($closestprox);
	$closestn=trim($closestn);
	$screen=trim($screen);
	$link=trim($link);
	$country=trim($country);
	$check_1hourphoto=trim($check_1hourphoto);
	$check_drivethrurx=trim($check_drivethrurx);
	$check_24hour=trim($check_24hour);
	$check_gnc=trim($check_gnc);
	$check_riterewards=trim($check_riterewards);
	$check_picturemaker=trim($check_picturemaker);
	$check_photoramp=trim($check_photoramp);
	$miles=trim($miles);
	$maxshow=trim($maxshow);

$myVars="";

$vars=array('$streetaddress');

for(reset($vars); $key=key($vars); next($vars) ) {
$myVars.= $key . "=" . urlencode(trim($$key)) . "&";
}

How can I make $vars equal to the values of all my variables? I had this working before using the code below, but don't want to use $HTTP_GET_VARS:

$myVars="";

for(reset($HTTP_GET_VARS); $key=key($HTTP_GET_VARS); next($HTTP_GET_VARS) ) {
$myVars.= $key . "=" . urlencode(trim($$key)) . "&";
}

Thanks.

Here's the easy way...

On your form use the following syntax to name your inputs...

<input type=text name = myArray[city]>
<input type=text name = myArray[zip]>

etc...

When you hit submit, php will post you an array called myArray containing all the inputs.

This technique is covered in the php manual.

What should the below code look like then? because if I changed the form names and my form doesnt display any results because the url has the word myArray before each variable.

$myVars="";

for(reset($myArray); $key=key($myArray); next($myArray) ) {
$myVars.= $key . "=" . urlencode(trim($$key)) . "&";
}

Thanks!

Try it and see. It's standard php functionality - so it will work. Also, you should be posting the form contents (no url parameters involved).

for(reset($myArray); $key=key($myArray); next($myArray) ) { 
$myVars.= $key . "=" . urlencode(trim($$key)) . "&"; 
} 

I'm not even going to attempt to try and understand what you are doing with that lot!
