Data Validation

[roelmagpoc]

Is there a way to validate data entered without the use of dropdowns and cascading dropdowns?

 

e.g. If a Site ID entered is not part of the related table, then error message after data entry or restricted during submission of record.

It looks more like it needs server side programming. You can try to contact Caspio developers http://www.caspio.com/support/professional-services.aspx

Hi Heisenberg,

 

One-to-many relationship with 'Enforce referential integrity' option seems can help you (http://howto.caspio.com/tables/table-relationships.html).

Hi, just want to add in the previous comment above, you may use a calculated field that will determine if that value is already existing in your table and just add a JavaScript that will prevent the form to be submitted if the value is existing:

CASE WHEN 
(SELECT COUNT(field_name) FROM Table_name WHERE fieldname = [@field:fieldname]) = [@field:fieldname] THEN
'Existing' 
ELSE
'Not Existing'
END

Then, you may add this JavaScript in the footer of your DataPage:

<script>

 document.addEventListener('BeforeFormSubmit', clickHandler);

function clickHandler(event) { 

var calc = document.querySelector("[id*=fieldID]").innerText;

 

if (calc  == "Not Existing"){

event.preventDefault();

window.alert("Submission BLOCKED!");

}

else {
document.location = "http://www.mysite.com/menu.html";
}

}

</script>

 

Just change the field names and table names depending on the field that you are using.

Hi,

There is a similar question in this post. Maybe you will find it useful.

Just to add, if you also wish to validate value entered in an input field to make sure that it follows this format: www.websitename.com

Then you can use this code:

 

<script type="text/javascript">

document.addEventListener('BeforeFormSubmit', function(event) {

var inputField = document.querySelector('#InsertRecordNameofField');

  const value = inputField.value;
  const regex = /^www\.[a-zA-Z0-9-]+\.[a-zA-Z]{2,}$/;

if (!regex.test(value)) {
event.preventDefault();
alert('Invalid Submission!');

} else {

document.form["caspioform"].submit();

}

});
</script>

Make sure to replace "NameofField" with the actual name of the field that you want to validate before submitting.
