Hi, I have a form for uploading multiple files. I need to rename the files according to a specific nomenclature that I obtain through the data and variables entered in the "File name provider" field. The variable {var: upload1.file.name} makes up a part of the entire file name. I noticed that some users upload files that have names with spaces, special characters, minus sing ecc. that I would like to delete.
For example, if a file with the name "file_1 annex-1 (copy 1) .docx" is uploaded, how can I turn it into "file1annex1copy1"?
​
Thank you

Hi GKCE3U,

Please see this thread for the basics - you will need a little custom PHP to clean the name - probably using a RegExp.

Thanks, through php code (which I called cleanname) I managed to get the file name without special characters. Now, however, if in the "File name provider" I use the variable {var:cleanname} I get the file name in square brackets eg.["Nomefileclean"].docx
How can I get the filename only?
​
Thank you

Hi GKCE3U,
​
I'm guessing that your PHP may be creating an array rather than a string???

Hi Bob,
The array is created because I allow multiple file uploads, so I set the "multi file selected?" to yes and the name of the file field ends with square brackets (filename[]).
With the php code I called rename, I take the filenames, delete the special characters and return an array variable.
This is the php code:

$inputFileName = $this->data("filename");
$search = ['_','-','+',' ','.','(',')','doc','docx'];
$cleanName = str_replace($search,'', $inputFileName);

return $cleanName;
​
In this case if the input uploaded files are:
(1) test_abcdefgh(copy 1).docx
(2) test_abcdefgh_2.docx
(3) test_abcdefgh.3.docx
​
the array variable $cleanName contain:
​
array(3) { [0]=> string(13) "testabcdefgh1" [1]=> string(13) "testabcdefgh2" [2]=> string(13) "testabcdefgh3" }
​
Now, I would like to rename the files as follows:
​
userid_cleanName.docx
​
ex:
​
700_testabcdefgh1.docx
700_testabcdefgh2.docx
700_testabcdefgh3.docx
​
I don't understand the correct syntax that I have to use in the "File name provider".
I've tried this
​
{user:id}_{var:rename.cleanName}.{var:upload3.file.extension}
{user:id}_{var:cleanName}.{var:upload3.file.extension}
​
but it doesn't work, the results are: 700_.docx
​
​
Could you help me?
​
Thank you.

I can add a solution for this in v7, but of course you will need to remake this form in v7, if this is something you are interested in then please let us know!
