Filename length

Forms SharePoint 2019
1

Hello,
I have a list or library to upload files. On upload, a popup (Dialog) box is shown to update metadata.
The scenario is that on update, I save the form to be able to update the status. After that the metadata dialog is opened.
Problem here is: I have added a validator to check the length of the uploaded file. but this does not work with the normal fd.save().
What I want to achieve is to first check the length of file, if it is not valid, then show the error without opening the dialog.
This is what i have so far:

fd.control('InitialFilesTable').$on('change', function (changeData) {
        if (changeData.type === 'upload') {
            dstat = 'Initial';
            $('.submittedGrid').show();
            addReviewSharingButton('InitialFilesTable', 'b72cef8a-f671-45e2-ba9d-d288c6ab6881');
            if (fd.field('Initial_Reset').value) fd.field('Initial_DMPUploaded').value = true;
            else if (fd.field('InitialStatusDmpReview').value === 'Reviewed, new upload needed') {
                fd.field('Initial_DMPUploaded').value = true;
                $('#initialTableMsg').html('New DMP uploaded... <b>Please wait for new review.</b>');
            }
            $('#DStatus').html(dstat);
        }
        if (changeData.type === 'delete') {
            dstat = 'No DMP';
            $('.submittedGrid').hide();
            $('.btn-info').hide();
            $('#DStatus').html(dstat);
        }
        fd.field('Status').value = dstat;
        fd.save();
        fd._showAlert = function () { };
    });

function validateFilesUpload() {
    fd.validators.push({
        name: 'DMP upload validator',
        error: 'Error Message',
        validate: function () {
            var initTable = fd.control('InitialFilesTable').widget.dataItems();
            if (initTable.length === 1) {
                var initialFilename = initTable[0].FileRef;
                if (initialFilename.length > 155) {
                    this.error = 'Please shorten your initial filename. Maximum allowed characters is 155.'
                    return false;
                }
            }
        }
    });
}

function OpenMetadata() {
    fd.control('InitialFilesTable').ready().then(function (dt) {
        fd.control('InitialFilesTable').$on('filesUploaded', function (itemIds) {
            validateFilesUpload();
            if (fd.isValid) openDialog('2f8e98a9-991e-4403-b5ea-0abdfe65123e');
        });
    });
}

Could you please see how to solve this?
Thanks in advance for the help.

Hello @asmita_adh,

You can try adding the setTimeout() method to trigger form validation. I also updated the code to validate file name length:

fd.validators.push({
    name: 'DMP upload validator',
    error: 'Error Message',
    validate: function() {
        var initTable = fd.control('SPDataTable2').widget.dataItems();

        for (let i = 0; i < initTable.length; i++) {
            var fileName = initTable[i].FileLeafRef.substring(0, initTable[i].FileLeafRef.lastIndexOf("."))
            if (fileName.length > 155) {
                this.error = 'Please shorten your initial filename. Maximum allowed characters is 155.'
                return false;
            }
        }
        return true;


    }
});

function fileNameValid() {
    if (fd.isValid) {
        alert('form is valid')
    } else {
        alert('form is invalid')
    }
}

fd.control('SPDataTable2').$on('filesUploaded', function(itemIds) {
    setTimeout(fileNameValid, 1000)
});
