gett unknown values from header

Gasolene

I have a form that sends vars to a php page.

it sends a known number of vars named columnX where X is a number. ie: column1, column2, ect...

ex:
<form action='phppage.php'>
<input type='text' name='column1' value='hi'>
<input type='text' name='column2' value='bye'>
<input type='text' name='column3' value='ect'>
<input type='submit'>
</form>

I want to read the value from these vars, how do i do that??
note: the ****** is the column value

if( $table )
{
$resultObj = new cResultSet();
$result = $resultObj( "select * from [".str_replace("%20", " ", $table)."]" );

for( $iCol = 0; $iCol < $iCount; $iCol++ )
{
$resultObj->exec_query( "update [".str_replace("%20", " ", $table)."] set [".$result[$iCol]."] = ********* where id = $update" );
}
}

ex:
<form action='phppage.php'>
<input type='text' name='column1' value='hi'>
<input type='text' name='column2' value='bye'>
<input type='text' name='column3' value='ect'>
<input type='submit'>
</form>

To access the above columns programmatically is simple. Here is a whole test script I wrote up quick. It uses $_POST as the form's method is POST, you can change the method to what every you like.

<html>
<body>
<form action='test.php' method="POST">
<input type='text' name='column1' value='hi'>
<input type='text' name='column2' value='bye'>
<input type='text' name='column3' value='ect'>
<input type='submit'>
<br>
<?php

if (isset($_POST['column1'])) {
$iCount = 3;
	for( $iCol = 1; $iCol <= $iCount; $iCol++ )
	{
		echo "TEST: " . $_POST['column'.$iCol] . "<br>";
	}

}
?>
</form>
</body>
</html>

(isset($_POST['column1'])) fails.

I know the vars are posted because
echo $column1; // outputs proper value

I tried adding global $_POST;

form tag...
<form action='".$PHP_SELF."' method ='POST'>

What version of PHP are you running?

You have 'register_globals' on because you mention that '$column1' works.

I know the vars are posted because
echo $column1; // outputs proper value

The 'register_globals' value can be changed in your php.ini, I have code at the bottom to do what you want with 'register_globals' on but its not the best way to do things.

http://us2.php.net/manual/en/language.variables.predefined.php

Also $_POST is introduced as of PHP 4.1.0, (use $HTTP_POST_VARS for earlier versions).

http://us2.php.net/manual/en/reserved.variables.php#reserved.variables.post

Code with 'register_globals' on, (not the best way):

for ($colNum = 1;$colNum <= 3; $colNum++) {
     $col = 'column' . $colNum;
     echo $$col;
}

Code for non-$_POST PHP systems (<= PHP 4.1.0):

for ($colNum = 1;$colNum <= 3; $colNum++) {
     $col = 'column' . $colNum;
     echo $HTTP_POST_VARS[$col];
     // Same as 'echo $_POST[$col];' in PHP systems that have $_POST variable
}
