HTTP_POST_VARS...

Hi there ppl,

Just starting out with PHP4 and require a little assistance with register_globals = Off. The 2 php pages work fine with the register_globals = On, but I must be using the HTTP_POST_VARS incorrectly or something.

states.php is as follows:
<?php
$StatesOfTheUSA = array (1 => "Alabama", "Alaska", "Arizona", "Arkansas", "California", "Colorado", "Connecticut", "Delaware", "Florida", "Georgia", "Hawaii", "Idaho", "Illinois", "Indiana", "Iowa", "Kansas", "Kentucky", "Louisiana", "Maine", "Maryland", "Massachusetts", "Michigan", "Minnesota", "Mississippi", "Missouri", "Montana", "Nebraska", "Nevada", "New Hampshire", "New Jersey", "New Mexico", "New York", "North Carolina", "North Dakota", "Ohio", "Oklahoma", "Oregon", "Pennsylvania", "Rhode Island", "South Carolina", "South Dakota", "Tennessee", "Texas", "Utah", "Vermont", "Virginia", "Washington", "West Virginia", "Wisconsin", "Wyoming");
for ($counter=1; $counter<51; $counter++) {
echo"<OPTION>$StatesOfTheUSA[$counter]</OPTION>";
}
echo "</SELECT>

";
for ($counter=1; $counter<51; $counter++) {
echo"<INPUT TYPE=HIDDEN NAME='HiddenState[]' VALUE='$StatesOfTheUSA[$counter]'>";
}
echo "<INPUT TYPE=SUBMIT></FORM>";
?>

capitals.php is as follows:
<?php
$StateCapital = array (0 => "Montgomery", "Juneau", "Phoenix", "Little Rock", "Sacramento","Denver","Hartford", "Dover","Tallahasse", "Atlanta", "Honolulu", "Boise", "Springfield","Indianapolis", "Des Moines", "Topeka", "Frankfort", "Baton Rouge","Augusta","Annapolis","Boston", "Lansing", "Saint Paul","Jackson", "Jefferson City", "Helena","Lincoln", "Carson City","Concord", "Trenton","Santa Fe", "Albany", "Raleigh","Bismarck","Columbus","Oklahoma City", "Salem", "Harrisburg", "Providence", "Columbia","Pierre", "Nashville", "Austin","Salt Lake City", "Montpelier","Richmond","Olympia","Charleston" , "Madison","Cheyenne");
for ($counter=0; $counter<50; $counter++)
{
if($HiddenState[$counter]==$State)
{
echo"The State capital is $StateCapital[$counter]";
}
}
?>


These work fine with register_globals = On , so could somebody show me how to use the HTTP_POST_VARS correctly in this scenario?

Thanks.

All I can say is this is the strangest piece of code i've ever seen and way more complicated than it needs to be... Here's my take:

states.php

Code: Select all

<FORM ACTION="capitals.php" METHOD=POST>
What state do you want to know the capital of?
<SELECT NAME=State>

<?php
$StatesOfTheUSA = array (0 => "Alabama", "Alaska", "Arizona", "Arkansas", "California", "Colorado", "Connecticut", "Delaware", "Florida", "Georgia", "Hawaii", "Idaho", "Illinois", "Indiana", "Iowa", "Kansas", "Kentucky", "Louisiana", "Maine", "Maryland", "Massachusetts", "Michigan", "Minnesota", "Mississippi", "Missouri", "Montana", "Nebraska", "Nevada", "New Hampshire", "New Jersey", "New Mexico", "New York", "North Carolina", "North Dakota", "Ohio", "Oklahoma", "Oregon", "Pennsylvania", "Rhode Island", "South Carolina", "South Dakota", "Tennessee", "Texas", "Utah", "Vermont", "Virginia", "Washington", "West Virginia", "Wisconsin", "Wyoming");
for ($counter=0; $counter<50; $counter++) {
	echo"<OPTION VALUE='$counter'>$StatesOfTheUSA[$counter]</OPTION>"; 
}
echo "</SELECT>

";
echo "<INPUT TYPE=SUBMIT></FORM>";
?>

capitals.php

Code: Select all

<?php
// Get your POST vars
$State = $HTTP_POST_VARS[State];
$HiddenState = $HTTP_POST_VARS[HiddenState];

$StateCapital = array (0 => "Montgomery", "Juneau", "Phoenix", "Little Rock", "Sacramento","Denver","Hartford", "Dover","Tallahasse", "Atlanta", "Honolulu", "Boise", "Springfield","Indianapolis", "Des Moines", "Topeka", "Frankfort", "Baton Rouge","Augusta","Annapolis","Boston", "Lansing", "Saint Paul","Jackson", "Jefferson City", "Helena","Lincoln", "Carson City","Concord", "Trenton","Santa Fe", "Albany", "Raleigh","Bismarck","Columbus","Oklahoma City", "Salem", "Harrisburg", "Providence", "Columbia","Pierre", "Nashville", "Austin","Salt Lake City", "Montpelier","Richmond","Olympia","Charleston", "Madison","Cheyenne");
for ($counter=0; $counter<50; $counter++) {
	if($counter==$State) {
	echo"The State capital is $StateCapital[$counter]";
	exit;
	}
}
?>

Please note:
$HiddenState = $HTTP_POST_VARS[HiddenState];
is completly useless... it isn't used, I changed the code after I put that in and forgot to take it out.
