Loop through directory and zip specific folder without parent path - linux

Question

I'm trying to make a bash script to loop through all folder in directories, and individually zip just the folder I want without all path and choose where to zip theme.
#!/bin/bash
for dir in /MyPersonalFolder/*/*/WhatIWantFolder
do
folder_number=$(basename ${dir%/*}) ### basename get the name of this folder [*] 'folder have numbers' /MyPersonalFolder/*/[*]/WhatIWantFolder
sudo tar -cf "${folder_number}-WhatIWantFolder".tar.gz --absolute-names "$dir"
mkdir -p ./backup-theme/ && sudo mv "${folder_number}-theme".tar.gz $_ ### I use this to move zipped folder to specific directory if i can choose where to zip file in the zip command line it's better
done
I can zip the folder I want, but the output zip file comes with this content:
/MyPersonalFolder/0001/0001/WhatIWantFolder
But what I need is to output the file with this path:
0001/
|___WhatIWantFolder/
I tried to change "$dir" in this line
sudo tar -cf "${folder_number}-WhatIWantFolder".tar.gz --absolute-names "$dir"
with basename ${dir%/*}
sudo tar -cf "${folder_number}-WhatIWantFolder".tar.gz --absolute-names "basename ${dir%/*}"
tar not found the folder it's come with errors
tar: e0001: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors

You can cd to another directory while running tar using the --cd option.
#!/bin/bash
for dir in MyPersonalFolder/*/*/WhatIWantFolder; do
parent="${dir%/*/*}"
subdir="${dir#*/*/*}"
outfile="backup-theme/${subdir/\//-}.tar.gz"
tar --cd "$parent" -cvzf "$outfile" "$subdir"
done
The directory structure of the tar file would look something like this:
tar -tf backup-theme/0001-WhatIWantFolder.tar.gz
0001/WhatIWantFolder/
0001/WhatIWantFolder/f1
