values form PHP in JS/HTML

Texx__insane

I have a JavaScript which is calculating some things based on exchange rate, In this script I use 2 values for EURO and USD which I get them from a form.

calcul.html
...
<SCRIPT LANGUAGE="JavaScript">
....
var eq_euro = document.frm_taxe.eq_euro.value;
var eq_usd = document.frm_taxe.eq_usd.value;
....
</script>
....
<form name="frm_taxe" action="index.php?id=calculator" method="post">
...
<input type="hidden" name="eq_euro" value=111>
<input type="hidden" name="eq_usd" value=222>
....
</form>

I want to get this values "eq_euro" and "eq_usd" from a PHP script written in another page.

curs.php

<?
echo '<style type="text/css">

</style>';
$file = fopen("http://www.bnro.ro/Ro/Info/", "r");
if (!$file)
{
echo "<p>Imposibil sa deschid fisierul pentru citire.";
exit;
}
$today = date("d-m-Y");
$numeValuta = array("Dolar SUA","Euro","Gram Au","Dobinda luna curenta");
echo '<table border="0" cellspacing="5" cellpadding="0" class="normal">';
echo '<tr><td><div align="center">Curs valutar
<strong>'.$today.'</strong><br>
(<a href="http://www.bnro.ro/Ro/Info/" target="_blank">sursa BNR</a>)
:</div></td></tr>';
echo '<tr><td align="center" valign="top">
<table border="0" cellspacing="5" cellpadding="0" class="normal">';
while (!feof($file))
{
$line = fgets($file, 1024);
// se executa cautarea in fisier
if (eregi('<TD class="bold">(.*)</TD>', $line, $out))
{
$cursvalutar = each ($out);
// se afiseaza ce sa gasit in fisier
while (list($key,$val)=each($numeValuta))
{
if ($val == "Dobinda luna curenta")
{
$moneda = "%";
}
else
{
$moneda = "Lei";
}
if ($val == "Euro")
{
echo "<tr><td>".$val."</td>".$cursvalutar[1].
"<td>".$moneda."</td></tr>";
$euroi=$cursvalutar[1];
}
if ($val == "Dolar SUA")
{
echo "<tr><td>".$val."</td>".$cursvalutar[1].
"<td>".$moneda."</td></tr>";
$dolarel=$cursvalutar[1];
}
if ($val == "Gram Au")
{
echo "<tr><td>".$val."</td>".$cursvalutar[1].
"<td>".$moneda."</td></tr>";
$auri=$cursvalutar[1];
}
if ($val == "Dobinda luna curenta")
{
echo "<tr><td>".$val."</td>".$cursvalutar[1].
"<td>".$moneda."</td></tr>";
$dobanzi=$cursvalutar[1];
}
break;
}
}
}
fclose($file);
echo '</table></td></tr></table>';
?>

I tried to use $cursvalutar[1] and $cursvalutar[2] as values but I think I have some sintac problems (in case is correct what I’m trying to do 🙂 )
Thx

U can make your file calcul.html calcul.php and echo your currency there:

calcul.php

<SCRIPT LANGUAGE="JavaScript"> 
.... 
var eq_euro = <?=$euroi;?>; 
var eq_usd = <?=$dolarel;?>; 
.... 
</script>

to have thoes values there, u either include your curs.php file into your calcul.php or set a session with thoes values ...

It doesn't work, I get some NaN values in the JS page.
Any other ideas ?

Try to convert them to integer or double or anythig u want:

<SCRIPT LANGUAGE="JavaScript"> 
.... 
var eq_euro = <?=(int) $euroi;?>; 
var eq_usd = <?=(int) $dolarel;?>; 
.... 
</script>

Texx__insane

still doesn't work,

the first time the JScript was before the

<?php include 'curs.php' ?>;

line,
I moved the JScript at the end of the calcul.php but no results.

Now the NaN error doesn't appear anymore but no calculs are made. Nothing happens.

Any hints? 😃

Just view source and see if your script look something like:

<SCRIPT LANGUAGE="JavaScript">
.... 
var eq_euro = 3,5853; 
var eq_usd = 2,8646; 
.... 
</script>

and u need to replace comma "," with dot ".".
And maybe use a javascript conversion parseFloat or double ...
