Upload of some filetypes not working (psd, ai, …)

[stainianer]

I already have your code to allow different filetypes in my functions and also define(‘ALLOW_UNFILTERED_UPLOADS’, true); in my wp-config.php

Nothing works.

For ai it shows a not allowed message and for .psd it shows a image with “Wrong Format or Size”.

Hello, when you get this message “Sorry, this file type is not permitted for security reasons.” it means that the restriction is coming from WordPress not out plugin, we can’t assist we that but we can suggest using the following code:

function wpali_custom_upload_mimes($mimes = array()) {

	$mimes['ai'] = "application/postscript";
	return $mimes;
}
add_action('upload_mimes', 'wpali_custom_upload_mimes');

For the second message, you might be just uploading a large file, try with a smaller one a see if it’s going to be uploaded or not

Filesize of both files, ai and psd, is nearly the same. I already got your code in my functions.php and i looked in the first admin-ajax.php request when uploading a file. It shows all possible filetypes:

1 image/jpeg
2 image/gif
3 image/bmp
4 image/vnd.microsoft.icon
5 image/tiff
6 image/svg+xml
8 application/zip
9 application/x-rar-compressed
10 application/pdf
11 image/psd
12 image/x-photoshop
13 application/photoshop
14 zz-application/zz-winassoc-psd
15 application/psd
16 application/postscript

You can try to upload a ai or psd here: https://www.print-tattoo.com/shop/schwarze-klebetattoos-mit-eigenem-motiv/

upload_max_filesize is 32m
