How to enforce required fields when the form is completed by clicking the signature

How do I enforce my required fields when the form is completed?

Is there a way to have an alert pop up when there are required fields are blank when I click on the signature box, letting the user know what boxes still need to be completed before you can finalize the form by signing it.

The "Required" field property is used to validate PDF forms submitted to a web page with scripting to process the form data, so it has no connection with the signature field unless you create that connection.

I would set the signature field to read only and hidden. I would create a button that runs a custom JavaScript to loop through all the fields on the form and test the value of the fields that have the "required" property set to true and track the fields whose value is equal to the default value of the field. If there any fields found where this condition is true then the form is not ready for signature. If none are found then unprotect the signature field.

I have tried this so many ways but when the fields aree completed on page1 the Siginiture on page2 does not unhide

Do you or anyone have some script itried

this.getField("Signature2").Readonly = !validateRequiredFields(this);

function validateRequiredFields(doc) {

var emptyFields = [];

for (var i=0; i<doc.numFields; i++) {

var f = doc.getField(doc.getNthFieldName(i));

if (f!=null && f.type!="button" && f.required && f.valueAsString==f.defaultValue) {

emptyFields.push(f.name);

}

if (emptyFields.length>0) {

app.alert("You must fill in the following fields:\n" + emptyFields.join("\n"));

return false;

}

return true;

}

Is there a tutorial how to make that? What button? And what would be the script. Thanks.

You can make the signature field read only and have a button next to it that runs a script to check that the required fields have been completed and if they are completed the signature field becomes unlocked.

Hi,

Could you help show what code to use to enable this?

Thanks!

You can validate the required fields, but you can't prevent the user from signing the form, unless you hide the signature field and then use a script (triggered from a button, for example) to only show it if all the required fields are filled-in.
