lack of server realtive path?

glyndower

/// $imagestmp= "http://www.domain.com/~dir/images/".$listnum."a.jpg";
if (file_exists ($imagestmp)){$image= "http://www.domain.com/~dir/images/".$listnum."a.jpg";}Else{$image= "../images/notavail.jpg";}

I've got the above code installed on several sites... after a server upgrade, it stopped working. Im told that becuase the sites are "jailed" on the new server that a server relative path will no longer work. so that brings us to the question....how can I amke this work w/o a relative path to the site that has the images? the way this works is there is one site that has the images dir...all the other sites pull the pictures from there.

Im not sure how to get php to check if file exists w/o a relative server path....?????

If your main page resides in:

http://somedomain.com/~dir/

and the image directory is:

http://somedomain.com/~dir/images/

did you try the following:


$imagestmp = './images/' . $listnum . 'a.jpg';

if (file_exists($imagestmp) ) {
     $image = $imagestmp;
} else {
     $image = '.images/notavail.jpg';
}

if you need to go back another directory you would


$imagestmp = './../images/' . $listnum . 'a.jpg';

if (file_exists($imagestmp) ) {
     $image = $imagestmp;
} else {
     $image = './../images/notavail.jpg';
}

or to simplify you might


$imageDir = './images/';
//  $imageDir = './../images/';

$imageExt = 'a.jpg';

$imagestmp = $imageDir . $listnum . $imageExt;

if (file_exists($imagestmp) ) {
     $image = $imagestmp;
} else {
     $image = $imageDir . 'notavail.jpg';
}

This is untested, but might be worth a try,

Sorry, I reread my post and realized I was unclear.

the images reside in a different domain...www.someotherdomain.com/images

/// $imagestmp= "/relative/server/path/to/some_other_domian_on_the_same server/~dir/images/".$listnum."a.jpg";
if (file_exists ($imagestmp)){$image= "http://www.domain.com/~dir/images/".$listnum."a.jpg";}Else{$image= "../images/notavail.jpg";}

Did you try using fopen with allow_url_fopen set to on in your php.ini

you might get away with


$baseDomain = 'http://someotherdomain.com/images/';

if ($fp = fopen( $baseDomain . $listnum . 'a.jpg', 'r') ) {
     $image = $baseDomain . $listnum . 'a.jpg';
} else {
     $image = './images/notavil.jpg';
}

fclose($fp);

Again untried but might help

That worked! Thank you!
