Can’t access image uploaded with WP_Image_Editor using php file_exist function.

    Hi,
    I am developing a podcast theme where i have a form that allows the user to upload their podcast cover arts. The Podcast cover art’s dimension should fall under 1400×1400 and 3000×3000 since we are following iTune’s regulations.
    Since such big files will impact the page load speed of the site i wanna resize the uploaded image to a smaller size, say 250×250 so that we can use that to display on our web pages.
    I have used WP_Image_Editor::resize function to resize the uploaded image and WP_Image_Editor::save function to save it. It actually worked. I now have two different images with two different dimensions.
    Since a lot of our user’s have already posted their podcast with the bigger images, i simply cannot exclusively show the compressed version. Instead i wanna check if a compressed version exists or not and show the image accordingly.
    I have used PHP’s file_exists function to check for the compressed version of the images. But it seems, it always returns false in the case of compressed images. But i can access it through the browser by typing in the full address.

    file_exists('path/to/original_image'); = true
file_exists('path/to/compressed_image'); = false

    I have used wp_handle_upload() to upload the original image but wp_image_editor class to resize and save the compressed one. So there must be something different with these two functions that’s causing this issue.

    Do you guys have any idea, how i can get over this ? Any help would be greatly appreciated.

    Thanks in advance.

  • You might be better off (especially if this is really a theme instead of a plugin) using the WordPress functions. Call add_image_size() and have the user add the image as an attachment (you can call wp_insert_attachment()). WordPress will do the generation of the sizes, and if the attachment is added to the content, will also output the srcset attribute on the image so that the correct size for the user’s device is used by the browser.
    And, with the new image size added, you can run Regenerate Thumbnails to fix all the old ones.

    Hi, I was un-aware of those two functions. Thank you for that. That would help me to reduce the compression process that i’m doing right now i think.

    Actually i found out the actual issue in my case, i was passing url to the wp_image_editor function instead of the file path. (Thanks to the thread i opened here) Once i pass the file path it is working. But the weird thing is that, even if i pass the wrong parameter to the wp_image_editor function the image seems to be uploaded somewhere as i am able to access it from the browser. But if i look for it through the FTP i can’t see it.

    Seems it is because of anything from the WordPress Hosting environment. That a whole new different discussion i suppose.
