[Resolved] processing in a loop :-s

[ihatelogon]

Hi,

I have just started picking up php, and have run into difficulties trying to create an admin section for a web poll. The web poll requires a text file containing something similar to the following:

Line1: Question
Line2: Option 1
Line3: 0
Line4: Option 2
Line5: 0

This is my code so far, but I can't seem to get it to process the options into an array. I should be able to get it to write the array to the text file as I have already wrote this part for the poll itself! Any help (corrected code!!! or similar) would be much appreciated,

cheers!

php from 'index.php'

<?php

echo ("<h1>Poll Creator</h1>");

if (!isset($step)) {
	$step = 1;
	}

if ($step == 1) {

echo ("<form action='index.php' method='post'>\nEnter number of options: <input type='text' name='number' size='2'>\n<input type='hidden' name='step' value='2'>\n<br><br><input type='submit' value='Next...'>\n</form>");

}

if ($step == 2) {

echo ("<form action='index.php' method='post'>\n\nEnter question: <input type='text' name='question' size='50'><br><br>\n");

for ($i=0; $i<$number; $i++) {

$j = $i + 1;

echo ("Enter option: " . $j . " <input type='text' name='" . $j . "' size='30'><br>\n");

}

echo ("<br><input type='checkbox' name='archive' value='no' checked> <font size='1'>Check this box to archive the existing poll</font>\n<br><input type='hidden' name='number' value='" . $number . "'>\n<input type='hidden' name='step' value='3'>\n<br><input type='submit' value='Submit'>\n</form>");

}

if ($step == 3) {

echo ($option);

$newdata[] = $question;

$number = $number + 1;

for ($i=1; $i<$number; $i++) {

$var = $i;
echo ($var);

$newdata[] = $var;

$newdata[] = 0;

}

print_r($newdata);

}
?>

I am going to start with the obvious. You are using code that requires register_globals to be on, however in any recent version of php, it would be disabled by default. try referring to the submitted $step as $_POST['step'] instead and see if that changes it.

Even if this doesn't solve the problem, it's a good idea for any new php user to understand how superglobals and such work and why they shouldn't use register_globals.

Cheers mate. I had a play around with these global variable things, and I have solved the problem!

Here is the final code which writes the text file required for the poll. Thanks for your help!

Ive even got it archiving existing polls! cheers again,

Ben

echo ("<h1>Poll Creator</h1>");

if (!isset($step)) {
	$step = 1;
	}

if ($step == 1) {

echo ("<form action='index.php' method='post'>\nEnter number of options: <input type='text' name='number' size='2'>\n<input type='hidden' name='step' value='2'>\n<br><br><input type='submit' value='Next...'>\n</form><br>");

}

if ($step == 2) {

echo ("<form action='index.php' method='post'>\n\nEnter question: <input type='text' name='question' size='50'><br><br>\n");

for ($i=0; $i<$number; $i++) {

$j = $i + 1;

echo ("Enter option <b>" . $j . "</b> <input type='text' name='" . $j . "' size='30'><br>\n");

}

echo ("<br><input type='checkbox' name='archive' value='yes' checked> <font size='1'>Check this box to archive the existing poll</font>\n<br><input type='hidden' name='number' value='" . $number . "'>\n<input type='hidden' name='step' value='3'>\n<br><input type='submit' value='Submit'>\n</form><br>");

}

if ($step == 3) {

if ($archive == yes) {

	$directory = opendir('archive/');
	$counter = -1; //accounts for current and parent directories ('.' and '..' respectively) AND adds one for new filename
	while (false !== ($file = readdir($directory))) { 
	       $counter++;
	   }
	closedir($directory); 

	$archivename = ("archive/" . $counter . ".txt");

	$olddata = file("poll.txt");
	$olddata = implode("", $olddata);

	$openfile = fopen($archivename, "w");
	fwrite($openfile, $olddata);
	fclose($openfile);

	echo ("New poll added <b>&</b> old poll successfully archived.<br><br>");

	} else {

	echo ("New poll added.<br><br>");

	}

$newpolldata[] = $question;

$number = $number + 1;

for ($i=1; $i<$number; $i++) {

$newpolldata[] = $_POST[$i];

$newpolldata[] = 0;

}

$newpolldata = implode("\n", $newpolldata);

$filename = fopen('poll.txt', 'w');
fwrite ($filename, $newpolldata);
fclose ($filename);
