Default Image help!?!?

[suess0r]

Hey i'm trying to do a call to check if an image exists, if so set the image to $id.jpg else set the image to default.jpg

[quote]echo '<b><p align="center"><img src="/images/clubs/logos/'.$id.'.jpg" align="center" width="300" height="128"></p>';[/quote]

Look up
http://us3.php.net/file_exists

The manual is really good if you just type in what you want it finds close functions.
[code]
if(file_exists($yourFile)){
  $id = 'default';
}else{
  $id = $yourFile;
}
[/code]

[code]
<?php
if (is_file(FULL_PATH_TO_YOUR_IMAGE))
{
$path = FULL_PATH_TO_YOUR_IMAGE;
}
else
{
$path = '/common/images/default.jpg';
}
$size = getimagesize($path);
?>
<p align="center">
<img src="<?php echo $path; ?>" <?php echo $size[3]; ?> />
</p>
[/code]

Thats a nice way of doing it - even adjusts for the height and width of the images incase they change!

here's how i have it set up and i'm about to try those other ways

but it's not working...

    $defaultImage = "/images/clubs/logo/default.jpg";

            $myImage = "/images/clubs/logos/".$id.".jpg";
           
            if (file_exists($myImage)) {
              $img = $myImage;
            } else {
              $img = $defaultImage;
            }

echo '<b><p align="center"><img src="'.$img.'" align="center" width="300" height="128"></p>';

What isn't working.
Just saying it isn't working doesn't give us much to go on.

[suess0r]

I'm sorry, it's just giving me a [x] where the picture should be. and i made sure the picture exists and it does...

[ToonMariner]

can you copy and past the html your script generates please..

try

if (file_exists($_SERVER['DOCUMENT_ROOT . $myImage))

see if that helps - sometimes i have a bit of bother with tgetting the path correct - purely because I am a lazy ass and can't be bothered to pay attention until someone else points out what I have doen wrong.

View the source of the outputted page. You probably have an HTML error now.

[suess0r]

Toon there's something wrong with that syntax with the ']' and you were right jesi i did have an html error on my dir i was calling the default...

problem now the default image shows up no matter what, even if the image does exist ;x

[suess0r]

OK so i've found out the root of the problem why it keeps posting the Default image no matter what....

[quote]  $defaultImage = "/images/clubs/logos/default.jpg";

            $myImage = "/images/clubs/logos/".$id.".jpg";
           
            if (file_exists($myImage)) {
              $img = $myImage;
            } else {
              $img = $defaultImage;
            }
       
      echo '<p align="center"><img src="'.$img.'" align="center" width="300" height="128"></p>';[/quote]

i did an echo on $myImage and it was the correct name of the image, and after the if statement i did an echo $img and it's default.jpg no matter what... so the if statement isn't working correctly with the file_exists() function... i tried the file_exists($_SERVER['DOCUMENT_ROOT.$myImage)) but the syntax isn't right...

IS there a better way to see if the file exists?!?

[ToonMariner]

suppose is_file is slighlty more desirable in this case but they do similar things.

remember that while html understands that '/images/this.jpg' is the same as 'http://www.asite.com/images/this.jpg' php doesn't. the string you put in there MUST let the scrip locate it from where teh scriupt is on teh server - which is why I tend to use $_server['document_root']

[Jessica]

/images is not your root folder. If images is a sub folder of the folder this php file is in you can do ./images
Otherwise you need your whole path which would be like $_server['document_root'].'/images..etc (or $_server['document_root'].'images...etc)
