PHP help - user defined variables

[KITT]

I need to create a form to post to another page containing all the user defined variables. Best I can come up with at the moment is this:

php said:

$array=$GLOBALS[GLOBALS]; foreach ($array as $i => $value) { echo "< input type=hidden name=$i value=$array[$i] >\n"; }

Trouble is this includes EVERY variable including server and environment ones. Anyone know how to just get the user defined ones?

cheers

I'd probably write them to a database and then use a session id to track and re-load them.

Alternatively you could use a cookie.

Or, you could filter out unwanted elements:

php said:

//get variables $passedVariableNames = array_keys( $_REQUEST); //reduce them to only those we want $passedAttributeNames = array_filter( $passedVariableNames, "ItemMatchesAttribute" ) ; //now walk through the array foreach( $passedAttributeNames as $attributeKey=>$attributeName) { // get the attribute id from the name $attributeNameItems = explode( $servSeparator, $attributeName); // the id will be the second item in the array $id = $attributeNameItems[ 1]; etc... Defined ItemMatchesAttributes thus: function ItemMatchesAttribute( $item) { global $attributePrefix; // check if the item starts with the attributeprefix return ( substr( $item, 0, strlen( $attributePrefix)) ==$attributePrefix); } Where you have defined attributeprefix something like: $attributePrefix = "ServAttr";

..if you follow me.

Trouble is $_REQUEST only gives the passed variables (form the previous pages POST request) and the function ItemMatchesAttribute looks to be comparing the variable name with whatever $attributePrefix is defined as. I don't know what the names are of the defined variables and hence can't do a comparison.

Closest I can get it to use $GLOBAL and create a list of ignorable names like GATEWAY_INTERFACE, SERVER_SOFTWARE etc.

Any more suggestions welcome

What I do is name all my form variables ServAttr_XXX where XXX changes. My filter function therefore removes all variables that don't start with this and then I explode it (on the '_') to get my proper variable name/value pair. Works for me I might be misunderstanding you though or this might not work for you.

Ah I see.

I'm actually writing some code that other web programmers will include in their own code and it needs to be able to pass on any defined variables to another page. Hence I won't know what variables have been defined by the other developer(s). I've created a solution where they use fill an array with the names of their defined variables so I can ensure they get passed on. It works for now anyway!

Can you just forward the $_POST vars? That way you only send what ever came through from the original form?

If not, how are these User Vars created?

php said:

if ($RandomVar=="" ) $RandomVar=GetValueForRadomVar(); //KITT's code here: include('kittscode.inc');

Now, kittscode.inc needs a way of knowing about $RandomVar so that when the page is reloaded with a POST form, $RandomVar has the original value.
