I am working with codeigniter. I want to display images but if some image is not exist it should show image-not-found-medium.jpg which is dummy image..

below is my code

<?php $image_path_medium = site_url('assets/images-products/medium'); $image_not_found_medium = $image_path_medium . "/" . "image-not-found-medium.jpg"; $image_name_with_path = $image_path_medium . "/" . $home_technology[$key]->product_sku . "-" . "a" . "-medium.jpg"; if (file_exists($image_name_with_path)) { echo $image_name_with_path; } else { echo $image_not_found_medium; } ?>

but it always shows $image_not_found_medium i think there is problem with my if condition. Please help.

  • Maybe site_url() returns something like http://my-site.com/assets/images-products/medium? If you want to use file_exists(), you have to provide a path to the filesystem where your code is running. Try replacing that line to be like this: $image_path_medium = $_SERVER['DOCUMENT_ROOT'].'/assets/images-products/medium';. Commented Jan 14, 2015 at 9:36
  • Looking at ellislab.com/codeigniter/user-guide/helpers/url_helper.html confirms what I've stated above. Commented Jan 14, 2015 at 9:42
  • done changes as per your suggestion.. but now also its avoiding if condition Commented Jan 14, 2015 at 9:47
  • Did you tried with a file that you are 100% that doesn't exist? Commented Jan 14, 2015 at 9:48
  • Can you, in a different file, do something like this: readfile('[path that was echoed on the other code]');? Commented Jan 14, 2015 at 9:51

"/" . $home_technology[$key]->product_sku . "-" . "a" . "-medium.jpg";//this is your image url $image_file_path=FCPATH.'assets/images-products/medium'. $home_technology[$key]->product_sku . "-" . "a" . "-medium.jpg";//this is your file path if (file_exists($image_file_path)) //file_exists of a url returns false.It should be real file path { echo $image_name_with_path; } else { echo $image_not_found_medium; } ?>

it showing /home/servername/public_html/my-site.com/assets/images-products/medium/imagenam‌​e.jpg
thanks, but it also didnt worked it always avoids if condition even if the image is available..
what does $image_file_path and $image_name_with_path prints
you said it was showing /home/servername/public_html/my-site.com/assets/images-products/medium/imagenam‌​‌​e.jpg now you saying file exists not working. echo $image_file_path and $image_name_with_path before if condition. and what you got.just write the full output.do not write whats going on
Thanks it worked, but / was missing in line $image_file_path=FCPATH.'assets/images-products/medium'. $home_technology[$key]->product_sku . "-" . "a" . "-medium.jpg"; before $home_technology[$key]->product_sku

You are using absolute path for file existence which is wrong. You have to use real path because the file_exists() function checks whether or not a file or directory exists on the current server.

If your assets folder is placed in root then just use getcwd() - Gets the current working directory as

$image_path_medium = getcwd().'assets/images-products/medium';

Otherwise give the proper path to the assets folder like

$image_path_medium = getcwd().'application/views/assets/images-products/medium';

Instead of file_exists() prefer is_file() when checking files, as file_exists() returns true on directories. In addition, you might want to see if getimagesize() returns FALSE to make sure you have an image.

Use like this.

$g = base_url().'upload/image.jpg'; if(file_exists($g) !== null){//your code..}

This is works for me in CI.
