When an image is imported, the name used in the media library is derived from the URL "basename". This can cause problems, especially when using the option "Search through the Media Library for existing images before importing new images". For example, even though they are different images, these URLs all have the same "basename" (in bold). They will generate the same file my-image.jpg in the WordPress library:
http:// example.com/ my-image.jpg
http:// example.com/ my-image?id=1
http:// example.com/subfolder/ my-image.jpg
The solution is to put this PHP code in your function editor:
function fix_img_url($url){
return empty($url) ? "" : $url."#/".substr(md5($url),0,8).".jpg";
}And put the following in your image field, substituting the correct field name for {image[1]}:
[fix_img_url({image[1]})]
This forces WP All Import to generate an image name derived from the entire URL instead of just the basename.
How does this work with external images downloaded from elsewhere?
e.g. in my settings > image box I have
https://www.example.com/folder/{listingnumber[1]}-1.jpg,
https://www.example.com/folder/{listingnumber[1]}-2.jpg,
https://www.example.com/folder/{listingnumber[1]}-3.jpg
I am finding duplicate images in media library after each import..... WPAI seems to add each file name ok e.g.
listingnumber-8-3.jpg
but the previous import named it:
File name: listingnumber-8-2.jpg
so how can I use the technique with my usecase?
Thanks
