If image exsists

[erme]

Hi,

 

Is there any way of searching for an image in a directory and saying 'if image exsists do this, else display defaullt image'

 

Many thanks

file_exists();

<?php
$filepath = "/home/test.jpg";
if(file_exists($filepath)) {
  
}
?>

if(file_exists($path))

{

    //use file

}

else

{

  // use default

}

This is what I now have:

 

    $filepath = "http://address.co.uk/images/test/" . $r['County'] . ".gif";
    
    
    echo $filepath;
    
    if (file_exists($filepath)) {
      echo "\n<a href=\"#\"><img src=\"/images/test/" . $r['County'] . ".gif\" /></a>\n";
    } else {
      echo "\n<a href=\"#\"><img src=\"/images/test/default.gif\" /></a>\n";
    }

 

However the 'default.gif' always gets displayed even though 'echo $filepath;' displays the correct path (depending on what page i'm on defining County)

OK I've managed to figure out it wasn't working for the path. Once I changed the path that the actually php was located .. it worked!

 

Is there a way around this?

The way to be certain is to always put the full url in the src attribute

I tried that. Still didnt work. Its as though the image HAS to be in the same folder as the php.

 

Could it be a server issue?

Well the issue here actually is that the path for the file_exists() call cannot be a url.

It has to be a filesystem path.

 

So dirname(__FILE__).'/images/....  would work for the check, and the url would work for the src attribute

Right ok, how would I do somethis like this ..

 

    $path = "/images/test/" . $r['County'] . ".gif";
    $filepath = dirname(__FILE__) $path;
    echo $filepath;

No worries, worked it out myself:

 

    $filepath = dirname(__FILE__). "/images/test/" . $r['County'] . ".gif";
    echo $filepath;
