Portal SharePoint file type upload restriction

Posted on by epilp

Hi all,

Does anyone know how to enable a restriction on file / mime types that can be uploaded into SharePoint, from an Advanced Form?The document subgrid is in a form tab that is mapped to an Advanced Form Step, which has a subgrid metadata item against it.

I would like to restrict document uploads to 'image/jpeg' files.

Thanks.

Hi @matt_epilp

You can use below code to restrict specific file type:
Go to your Advanced Form Step --> Form Options --> Add below javascript
$("input[name='file']").change(function() { var fileList = $("input[name='file']")[0].files; var isValid = true; if (fileList.length > 0) { for (var i = 0; i < fileList.length; i++) { if (fileList[i].type == "image/jpeg") { isValid = false; break; } } } if (!isValid) { $("input[name='file']").val(""); alert("You can not add images"); } });
