Group: Group1 Group2Chapter:
<input type="text" name="chapter">
Article:
<input type="text" name="article">
<input type="submit" value="Go to Article">
[/php]
[php]
<?php session_start(); $laws=array( "group1"=>array( "1"=>array( "1"=>"This is article (1) in chapter (1) of (group1)", "2"=>"This is article (2) in chapter (1) of (group1)", "3"=>"This is article (3) in chapter (1) of (group1)", ), "2"=>array( "1"=>"This is article (1) in chapter (2) of (group1)", "2"=>"This is article (2) in chapter (2) of (group1)", "3"=>"This is article (3) in chapter (2) of (group1)", ), ), "group2"=>array( "1"=>array( "1"=>"This is article (1) in chapter (1) of (group2)", "2"=>"This is article (2) in chapter (1) of (group2)", "3"=>"This is article (3) in chapter (1) of (group2)", ), "2"=>array( "1"=>"This is article (1) in chapter (2) of (group2)", "2"=>"This is article (2) in chapter (2) of (group2)", "3"=>"This is article (3) in chapter (2) of (group2)", ), ) ); /* (QUSTION 1) Before setting $_SESSION values with data from $_GET variables, how do I validate the $_GET values from the form with the following scheme?
