If image doesn't exist

[e1seix]

Quick query really, is there some sort of if statement we could use to say for example if an image url is invalid to display something else in it's place.

 

eg.

 

image url = "/happy_face.jpg" but there is not such image as "happy_face.jpg", therefore display "default.jpg" or something like that?

try this:

 

<?php

// series of codes
...

$picture = 'happy_face.jpg'; // you may also include the path

if(!file_exist($picture)) {
   $picture = 'default.jpg';
}

// the rest of the code to load a picture
...
?>

 

cheers,

 

Jay

I see what you're getting at, but for me there seems to be a problem - ie. Fatal error: Call to undefined function file_exist().

 

is there something i'm unaware of, or have i just implemented it incorrectly?

 

$picture = 'images/thumbs/tn_'.$row[image].'.jpg'; // you may also include the path

if(!file_exist($picture)) {
   $picture = 'images/thumbs/tn_default.jpg';
}

                        echo '<div id="bottomImage" style="background:#ffffff; background-image:url('.$picture.'); background-repeat:no-repeat;"><a href="/viewItem.php?sku='.$row[sku].'"><img height="100px" src="/images/thumbs/tn_mini.gif" width="100px" /></a></div>';

 

what i'm trying to say is that if $picture DOESN'T exist, then display default...

 

what's going on?

 

lol many thanks,

Hmm... file_exists() been around since php4.  What version are you using?

the if file exist defo work i am using it on a site i have up and running at the minute.  here is the code i used

 

$image = "";
$broad_img1= "";
$path= 'http://www.yourdomain.com/'; // sets the first half of the path
$web_image_folder = 'image/thumbs/broad/broad1';   // defines the folders to look in
$exts = array('jpg', 'png', 'gif', 'jpeg');  // sets up the array
$image_name = 'thumb_broad1';  
$size = 'width="200" height="200"';

// check for each extension
foreach($exts as $ext) {
   if (file_exists($web_image_folder.'/'.$image_name.'.'.$ext)) {
     $image = $image_name.'.'.$ext;
   } 
   
}

 

change it and use it.

you put file_exist not exists

 

should be

$picture = 'images/thumbs/tn_'.$row[image].'.jpg'; // you may also include the path

if(!file_exists($picture)) {
   $picture = 'images/thumbs/tn_default.jpg';
}

                        echo '<div id="bottomImage" style="background:#ffffff; background-image:url('.$picture.'); background-repeat:no-repeat;"><a href="/viewItem.php?sku='.$row[sku].'"><img height="100px" src="/images/thumbs/tn_mini.gif" width="100px" /></a></div>';

my bad... i forgot to add 's' on file_exist()... it should be file_exists().
