How do I do this? This is what I have tried and it is not working.

 

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">

<input type="submit" name="set" id="set" value="Set Variables" />

<input name="storeArr" name="storeArr" type="hidden" value="<?php echo serialize(htmlentities($arrVars)); ?>" />

</form>

 

and after the $_POST['set'] is set

 

$arrVars = unserialize(html_entity_decode(stripslashes($_POST['storeArr'])));

hey thorpe, thank you for your reply so far. I am trying to avoid posting all the codes here because it's going to look messy, unless you want me to. However, here is the relevant codes for $arrVars. Note that $arrVars is defined inside the bracket of an if statement. It is still on the same file. I have tried initializing $arrVars outside of the if bracket but the same thing happens.

 

$arrVars = acquireVars($varCount, $problem);

 

and the function acquireVars() is given below

 

function acquireVars(&$count, $text){

$token = strtok($text, " \n\t");

while($token)

{

if(substr($token,0,1) == '#'){

$count ++;

}

$token = strtok(" \n\t");

}

$arrVars[$count];

$i = 0;

$token = strtok($text, " \n\t");

while($token)

{

if(substr($token,0,1) == '#'){

$arrVars[$i] = new problemVar($token);

$i++;

}

$token = strtok(" \n\t");

 

}

return $arrVars;

}

 

and the problemVar ADT is

 

<?php

class problemVar {

var $myVar;

var $lowerRand;

var $upperRand;

var $myVal;

function __construct($var){

$this->myVar = $var;

$this->myVal = 0;

$this->lowerRand = 0;

$this->upperRand = 0;

}

function setUpper($n){

$this->upperRand = $n;

}

function setLower($n){

$this->lowerRand = $n;

}

function setVal(){

$this->myVal = rand($this->lowerRand, $this->upperRand);

}

function getUpper(){

return $this->upperRand;

}

function getLower(){

return $this->lowerRand;

}

function getVal(){

return $this->myVal;

}

function getVar(){

return $this->myVar;

}

function __toString(){

return $this->myVar;

}

}

?>
