Jquery validate csv file -

i try validate csv file when user upload file extension/format csv

<script type="text/javascript"> $(document).ready(function() {     $('#form1').validate({         rules: { csv: { required: true, accept: "csv"  }},         messages: { csv: "file must csv" }     });  }); </script>  <form action="product_import.php?action=import" method="post" name="form1" id="form1" enctype="multipart/form-data"> <input name="csv" type="file" id="csv" /> </form> 

but problem when upload file extension csv error message show file must csv , dont know why script can't accept set accept: "csv" .

my csv file name product.csv

the accept rule not file extensions, it's mime types.

you might want use the extension rule instead

demo: http://jsfiddle.net/c5r3b/

$(document).ready(function () {      $('#form1').validate({         rules: {             myfield: {                 required: true,                 extension: "csv"             }         }     });  }); 

however, both of these rules require inclusion of additional-methods.js file.
