Need help in this statement, please

[fubarur]

So I am trying to tweak a few things on a page and I am stuck on this one. I want the ###### to also be the data in $row['id']

 

<?php
if (file_exists('/var/www/html/images/races/######/images/' . $row['id'] . $dthumb)):
?>

 

so if $row['id'] = 124 it would be looking for

 

/var/www/html/images/races/124/images/124.jpg'))

 

I know it has to be that I am stumped on the correct question to ask or search for.

 

Any help is appreciated.

 

Thanks!

 $row['id'] = (int)$row['id']; // cast to int to make sure nothing bad gets through.
if (file_exists('/var/www/html/images/races/' . $row['id'] .'/images/' . $row['id'] . $dthumb)):

 

Should do what you want. This is called concatenation. I also statically cast the id to an integer, as that is what you are expecting and this will make sure that something weird doesn't go through that could be used to get information about your site (more than likely not, but better save than sorry).

 

Also, instead of manually typing the path in like that, I would use $_SERVER['DOCUMENT_ROOT'], if possible.

 

if (file_exists($_SERVER['DOCUMENT_ROOT'] . '/images/races/' . $row['id'] .'/images/' . $row['id'] . $dthumb)):

 

Assuming that has been set by your webserver and it is set to /var/www/html

Thank you for your advice. That did not work for some reason but I did get this to work

 

<?php

if (file_exists('/var/www/html/images/races/' . $row['id'] . '/images/' . $row['id'] . $dthumb)):

?>
