file_exists function

[benrob82]

hi can anyone help me with this function.

I've got it working to a point but I need the URL to contain $dir value

<?php
$dir = $gotevent[0];

$filename = '/var/[URL unfurl="true"]www/sites/crm.url.com/public_html/spgm/gal/$dir';[/URL]

if (file_exists($filename)) {
   echo "<a href='/spgm/index.php?spgmGal=$dir'><img src='/templates/taad/images/gallery.gif' alt='Event gallery - view the pics' width='234' height='37' border='0'></a><br><br>";
} else {
   echo "The file $filename does not exist";
}
?>

the line I'm having trouble with is

$filename = '/var/[URL unfurl="true"]www/sites/crm.url.com/public_html/spgm/gal/$dir';[/URL]

anye help would be great

You're doing all this inside single quotes. Variable references don't work inside single quotes. See the PHP manual on strings:

http://www.php.net/manual/en/language.types.string.php

Change:

filename = '/var/

http://www/sites/crm.url.com/public_html/spgm/gal/$dir';

For this:

filename = '/var/

http://www/sites/crm.url.com/public_html/spgm/gal/'

. $dir;
