if statement with images

[gazalec]

i was wondering if it is possible to have an if statement with image for example

 

<?

if("<img src='directory/pic.jpg'> == '' "){
echo
"<img src='directory/alternativepic.jpg'>";
}else{
echo
"<img src='directory/pic.jpg'>";
}

?>

 

if this isn't possible then does anyone know how to get this effect

 

Thanks

Your code is invalid and from your example it is difficult to tell what it is exactly your trying to do. Could you provide and explination in english?

You need to use the file_exists() in your "if" statement. One way follows:

<?php
$img = (file_exists('directory/pic.jpg'))?'pic':'alternativepic';
echo '<img src="directory/' . $img . '.jpg">';
?>

ok sorry i'm in the process of making a website with ALOT of products so instead of all the products having a separate page i'm making one php page that will call the products ID from a database and display everything needed so instead of having 500 pages i have 1, the only problem is some of the images dont have an image and i just wanted it so that if there is no image it displays an alternative image sayin, No image available or something along those lines and i was just wondering if it would be possible for PHP to look in the folder and if it doesn't find an image it displays the alternative.

 

thanks

I guess you d like to check if image exists?

 

Or .. if image is not blank file?

 

If you'd like to check if image exists try this:

<?php

if (file_exsists('dir/img.jpeg')

{

echo "<img src='dir/img.jpeg'>";

}

?>

 

If you'd like to check if image is not a blank file than the code would be:

<?

$minsize = "1000000"; //in bytes

$filepath = "dir/img.jpeg";

 

if ($minsize < filesize($filename))

{

echo "<img src='dir/img.jpeg'>";

}

?>

 

Hope this is it!
