include problem

[alin19]

i'm using an open flash chart to create a grafic

 

 

the problem is that the index file looks like this:

<?php
include_once 'ofc-library/open_flash_chart_object.php';
open_flash_chart_object( 1500,'90%', 'chart-data.php', false );
?>

 

and from the file chart-data.php is created the grafic image,

 

and if i want to select from what to create the grafic i can't without modifing the chart-data.php code,

 

 

i made an improvization by adding in the index file 2 input slots and then write those values into a include.php and in the cart-data.php include that file, but the problem is that if the second user wants to view something else that include.php is modified for the first user also,

index file modified:

<form method="POST">
<table>
<tr><td><input type="text" name="simbol"></td><td><input type="text" name="scadenta"></td><td><input type="submit" name="submit" value="submit"></td></tr>
</table>
</form>

<?php
include_once 'ofc-library/open_flash_chart_object.php';
open_flash_chart_object( 1500,'90%', 'chart-data.php', false );
$simbol=$_POST['simbol'];
$scadenta=$_POST['scadenta'];

$write = fopen('/opt/lampp/htdocs/include.php','w');

$scris="<?php \$simbol='$simbol'; \$scadenta='$scadenta'; ?>";
fwrite($write,$scris);

?>

 

and in the chart data.php

<?php
include '/opt/lampp/htdocs/include.php';
// generate some random data:
/*
srand((double)microtime()*1000000);

$max = 50;
$data = array();
for( $i=0; $i<12; $i++ )
{
  $data[] = rand(0,$max);
}
*/
$hostname="**9*";
$username="**";
$password="**";
$database="**";

$conexiune=mysql_connect($hostname,$username,$password)
or die ("Nu ma pot conecta la baza de date");

$bazadate=mysql_select_db($database,$conexiune)
or die ("Nu gasesc baza de date");

$cerereMin="Select min(`price`) from tranzactii where `contract`='$simbol' and `scadenta`='$scadenta'";
$cerAM=mysql_query($cerereMin);
$cerEM=mysql_fetch_array($cerAM);
$min=$cerEM[0];
$min=$min*1000;
$cerereMax="Select max(`price`) from tranzactii where `contract`='$simbol' and `scadenta`='$scadenta'";
$cerAMa=mysql_query($cerereMax);
$cerEMa=mysql_fetch_array($cerAMa);
$max=$cerEMa[0];
$max=$max*1000;
..

 

what can i do to transmit some vars from the index file to chart-data.php without saving them into a file?

Store it in a database?

is the same as storing it in a file, when the next user comes, it will update the record to the second user needs
