file_exists() question..NOT READING THE FILE CORRECTLY!

Copy linkTweet thisAlerts:
Apr 19.2005

Hello, I am working on a script that reads a record from a datbase and that becomes the image file name. If it is not found then it should display another default image. Here is my script:

[code=php]
 $imagefile = “/images/”. $row[“id”] . “.jpg”;
if (file_exists($imagefile)){
echo “<td colspan=”2″ rowspan=”3″><img class=”border” src=”.images”. $row[“id”] .”.jpg” width=”120″ height=”111″ />n”;
}
else {
echo “<td colspan=”2″ rowspan=”3″><img class=”border” src=”/images/defimage.jpg” width=”120″ height=”111″ />n”;
}
[/code]

I get a display of only the default image (“defimage.jpg”) and I do have files for some of the products. It displays fine if i take out that if else and file_exists(). Does anyone know if im using the correct function? I tried fopen() but that is definetely not the way to go…any suggestions or feedback is greatly appreciated..thanks!

@NogDogApr 19.2005 — I'm guessing you probably do not want the leading "/" in front of your "images" directory name (if that directory is right under the directory where your PHP page is).

@vicpal25authorApr 19.2005 — Well I am using relative links for my site and it seems that the function is not finding the file name correctly so the flag is setting off to display the default image "defimage.jpg".

@NogDogApr 19.2005 — "/images/filename.jpg" is not a relative link - it is an absolute link to a directory named "images" immediately under the root directory of the active filesystem. "images/filename.jpg" is a relative link to a directory named "images" under the currently active directory. "../images/filename.jpg" is a relative link to a directory which is at the same level as the currently active directory (".." means up one level in the directory tree).

@vicpal25authorApr 19.2005 — Gotcha! Thanks! But the flag aint being set up correctly with absolute or relative linking.

@NogDogApr 19.2005 — Just for the helluvit, try using is_readable() instead of file_exists(). The notes for file_exists() seem to indicate it could return false if running in safe_mode and if the file is not actually owned by the PHP user name (typically "nobody" under Apache).

@vicpal25authorApr 19.2005 — dang it..nope..i condensed my code just to get the functionallity and it is not working..im using

[code=php]
<?php
$imagefile = "/home/content/h/i/s/hispanonatura/html/images/1.jpg";
if (is_readable($_FILES[$imagefile])){
echo "success! it does exist";
}
else {
echo "it does not exist";
}
?>
[/code]

and

[code=php]
<?php
$imagefile = "/home/content/h/i/s/hispanonatura/html/images/1.jpg";
if (file_exists($_FILES[$imagefile])){
echo "success! it does exist";
}
else {
echo "it does not exist";
}
?>

[/code]

AND NO SUCCCESS..HUMMM..THIS IS BECOME FEISTY..

[code=php]
<?php
$imagefile = "/images/1.jpg";
if (is_readable($_FILES[$imagefile])){
echo "success! it does exist";
}
else {
echo "it does not exist";
}
?>
[/code]

@vicpal25authorApr 19.2005 — yess! i got it to work...i took off $_FILE from the variable and it worked. I had to use the server root but it worked..nice!

[code=php]
<?php
$imagefile = "/home/content/h/i/s/hispanonatura/html/images/1.jpg";
if (file_exists($imagefile)){
echo "success! it does exist";
}
else {
echo "it does not exist";
}
?>
[/code]

Success!
