Remove special characters from attachment?

[Margo]

Hello @shedev,

You can either add a custom validation for the Attachments filed to force user remove special characters:

fd.field('Attachments').validators.push({
    name: 'Attachments Validation',
    error: "remove special chatacters",
    validate: function(value) {
        const spch = /[!@#$%^()]+/;
        for (let i = 0; i < value.length; i++) {
            if (spch.test(value[i].name)) {
                return false
            }

            return true
        }
    }
}); 

Or replace the Attachments field with a List or Library control. This way you can rename files when they are uploaded to a document library, using the code:

var listOrLibrary = 'SPDataTable1';
var docLibraryTitle = 'DocumentLibraryName';
var docLibraryId = '2afe31be-ac14-49db-a0a8-bf8724bc8487';

fd.control(listOrLibrary).$on('filesUploaded',
    function(itemIds) {
        //get document library by Title
        var library = pnp.sp.web.lists.getById(docLibraryId);
        //go through each uploaded Item Id and set field values
        library.getListItemEntityTypeFullName().then(function(entityTypeFullName) {

            var batch = pnp.sp.web.createBatch();
            var currentName;
            var uri;


            for (var i = 0; i < itemIds.length; i++) {
                //specify which fields to update and how
                var itemId = itemIds[i];
                library.items.getById(itemId).select('FileRef', 'Id').get().then(function(item) {
                    return item

                }).then(function(item) {
                    uri = item.FileRef;
                    var fileID = item.Id;
                    filename = uri.substring(uri.lastIndexOf("/") + 1, uri.lastIndexOf(".")).replace(/[`~!@#$%^&*()]/gi, '');
                    var nbatch = pnp.sp.web.createBatch();
                    library.items.getById(fileID).inBatch(nbatch).update({
                        FileLeafRef: filename
                    }, "*", entityTypeFullName)
                    nbatch.execute().then(function() {
                        fd.control(listOrLibrary).refresh();
                    });
                });
            }
        });
    });
