Question

All of this stuff is for example (names aren’t actual).

Everything is also located on localhost:8080 (USBWebserver 8.5)

Directory Structure:
(Files located on localhost:8080/[project_name])

/ajax
    /ajax_file.php
/img
    /250x250
        /[image_name].jpg

Code (From ajax_file.php):

$url = 'img/250x250/'.$image_name.'.jpg';
$url = file_exists($url);

This will return false.

I’ve tried an img_exists($url) function which used cUrl that did not work.

I’ve also tried:

$url = 'img/250x250/'.$image_name.'.jpg';
$image_check = getimagesize($url);

if (!is_array($image_check))
{
    $url = 'img/default_image.png';
}

but this returns a warning for getimagesize() saying no file or directory exists.

When I put $url = 'img/250x250/'.$image_name.'.jpg' into <img src="$url" /> the image shows up…but if the image does not exist then it comes up with a broken image…

How come anything I try to do fails in some way?

I want a default image to show up when the image is broken :/

EDIT

$url = 'img/products/250x250/'.$image_name.'.jpg';
$url = var_dump(file_exists($url));
Returns bool(false)

$url = '../img/products/250x250/'.$image_name.'.jpg';
$url = var_dump(file_exists($url));
Returns bool(false)

Answer 1

It appears as if you need to branch out of the ajax folder before accessing img folder?

Try:

$url = '../img/250x250/'.$image_name.'.jpg';

My guess is that he put the img tag inside of the actual php page, not the ajax script.
