Can the attached file on submission form be retained if I'm prevented from submittin because I missed some fields that are required or have wrong data type?

Question

Hi,

I have a submission form with a couple of fields that are required (and they should also only accept numbers) along with a file field. The submission works fine, but say, when a user fills out all fields (including the file field) except for one of the number fields (or if i input a text instead of a number in one of the fields), when I hit submit, the page gets reloaded telling me to fill in all of the fields properly (to not leave any fields blank or to input only numbers), which is expected, but I noticed that the file I have attached earlier disappears. Is there anyway to retain the file when the validation arises?

Hi @cordova,

I have a workaround for this that uses JavaScript. Basically, the user gets prevented from submission when one of the fields is empty or the value is not a number. That way, the page doesnt have to be reloaded for the validation to occur. On Configure Fields of your DataPage, add a Header and Footer, and add this on the Footer:

 

<script>

document.addEventListener("BeforeFormSubmit", function(e){
var field1 = document.getElementById("InsertRecordNumber_1").value;
var field2 = document.getElementById("InsertRecordNumber_2").value;
var field3 = document.getElementById("InsertRecordNumber_3").value;

 if(isNaN(field1) || isNaN(field2)  || isNaN(field3) || field1.length == 0 || field2.length == 0 || field3.length == 0){
alert("Please enter a number on the fields.");
e.preventDefault();


}
else{


}

});

</script>

 

Wherein field1, field2, and field3 are my fields that should only accept numbers and should not be left empty. If you have more fields, make sure to declare them as variables too, as well as add them in the if condition.
