[RESOLVED] write function help

[scotte]

Hi guys,

I am looking for a solution. I have 6 variables that I want to assign true or false via a form set with radio buttons. The form on submit will write to a php page that will ultimatley be used by another php page via "include" to tell the script if these variables are on or off. I need to do this via a document save versus saving the true or false values in a database.

I have made the following code to do this

<?php

$cat_1 = $_POST["cat_1"];
//$man_1 = $_POST["man_1"];
//$new_1 = $_POST["new_1"];
//$find_1 = $_POST["find_1"];
//$info_1 = $_POST["info_1"];


if ($cat_1 == true){
	$fp = fopen('data.php', 'w');
	fwrite($fp, '<?php $cat_1 = true; ');}
	else {
	$fp = fopen('data.php', 'w');
	fwrite($fp, '<?php $cat_1 = false; ');}





if ($man_1 == true)
	fwrite($fp, '$man_1 = false');	

fclose($fp);

echo "success";
?>

Note this only deals with one of the variables that needs to be checked (once i get the code working there is another 5 or 6!). When I submit my form I always get "false" no matter whether the result from the form is true..

The following is my form

<form method="POST" action="submit.php">
	<!--webbot bot="SaveResults" U-File="_private/form_results.csv" S-Format="TEXT/CSV" S-Label-Fields="TRUE" -->
	<p>On&nbsp; I&nbsp; Off</p>
	<p><input type="radio" value="true" name="cat_1" checked>&nbsp;&nbsp;&nbsp;
	<input type="radio" name="cat_1" value="false">&nbsp;&nbsp;&nbsp; Categories</p>
	<p><input type="radio" name="man_1" value="true" checked>&nbsp;&nbsp;&nbsp;
	<input type="radio" name="man_1" value="false">&nbsp;&nbsp;&nbsp; 
	Manufactures</p>
	<p><input type="radio" name="new_1" value="true" checked>&nbsp;&nbsp;&nbsp;
	<input type="radio" name="new_1" value="false">&nbsp;&nbsp;&nbsp; What's New</p>
	<p><input type="radio" name="find_1" value="true" checked>&nbsp;&nbsp;&nbsp;
	<input type="radio" name="find_1" value="false">&nbsp;&nbsp;&nbsp; Quick 
	Find</p>
	<p><input type="radio" name="info_1" value="true" checked>&nbsp;&nbsp;&nbsp;
	<input type="radio" name="info_1" value="false">&nbsp;&nbsp;&nbsp; 
	Information</p>
	<p><input type="submit" value="Submit" name="submit"></p>
</form>

It all works correctly if i disable the form and write the variable into the script myself ie. $cat_1 = true

Ultimatley what i want is a document with the following output

<?php $cat_1 = true; $man_1 = false; $new_1 = true; $find_1 = false; $info_1 = true; ?>

(true and false values may differ obviously)

Any help is much appreciated!!

A simple loop is what you need.

<?php
$fileData = '<?php ';
foreach( $_POST as $key=>$value ) {
     $fileData .= "\$$key=$value; ";
}
$fileData .= '?>';
?>

and write $filedata to the file.

The reason your script didn't work is that the variables are set with the string 'true' or 'false', so it is always true (boolean)

Thanks so much for replying! The array works perfectly and god knows why i didnt think of it!

Now the problem is that they key of each is = to the result. So using the following code

<?php
$cat_1 = $_POST["cat_1"];
$man_1 = $_POST["man_1"];
$new_1 = $_POST["new_1"];
$find_1 = $_POST["find_1"];
$info_1 = $_POST["info_1"];

$fileData = '<?php ';
foreach( $_POST as $key=>$value ) {
     $fileData .= "${$key}=$value; ";
}
$fileData .= '?>';


$fp = fopen('data.php', 'w');
fwrite($fp, $fileData);
fclose($fp);
?>

The output is

<?php false=false; false=false; false=false; false=false; false=false; =Submit; ?>

Obviously the key is incorrect in that I need it to stay as $cat_1, $man_1 etc.

Any ideas where I am going wrong?

You probably need to escape the $

"\$$key
