cbFnInit (Function)
cbFnInit (Function)This callback function will be called during the initialization process of the form. If you plan on adding logic that takes time to complete (i.e. executes in the background), we recommend using the $zn.form.lock function to lock the form and unlock it after the task is complete.
cbFnPreValidate (Function)
cbFnPreValidate (Function)This callback function is invoked after the form submission process is triggered, but before Zingy's automatic field input validation process. Use this function to implement custom or complex validation logic prior to the automatic validation process. Use the $zn.form.getFieldValue and $zn.form.setFieldValue functions to get/set the value of the fields. Use the $zn.form.setStatus function with a false value, to indicate any errors. The $zn.form.setStatusMessage function can be used to specify the actual error to the user. If there are no pre-validation errors, you do not need to call $zn.form.setStatus with a true value. Please note that you cannot execute a background task and wait for it's completion here.
cbFnPostValidate (Function)
cbFnPostValidate (Function)This callback function is invoked after Zingy's automatic field input validation process but prior to data submission.

At this stage of the form's submission use of $zn.form.getFieldValue and $zn.form.setFieldValue functions is not recommended since the system has already progressed beyond the reading of field input values. Use the $zn.form.setStatus function with a false value, to indicate any errors. The $zn.form.setStatusMessage function can be used to specify the actual error to the user. If there are no post-validation errors, you do not need to call $zn.form.setStatus with a true value. Please note that you cannot execute a background task and wait for it's completion here.

cbFnSubmit (Function)This callback function is invoked only in the case of custom forms which are not attached to any database table. Implement your own form data submission logic here. The $zn.form.getFormData function can be used retrieve the object representing the data to be submitted. The data can be sent to HTTP/REST API calls, webhooks or any other destination including Zingy's database (using the functions provided by $zn.db). Since submission of data is usually an asynchronous task, you need to call the $zn.form.customSubmitComplete function after your custom submission logic finishes. Prior to calling $zn.form.customSubmitComplete, you need to call $zn.form.setStatus to indicate the success or failure status. The $zn.form.setStatusMessage function can be used to indicate the outcome information. If not, he Zingy form's default success and error messages will be shown.
cbFnSuccess (Function)
cbFnSuccess (Function)This callback function is called after the form's data has been submitted succesfully. The $zn.form.getFormData function can be used retrieve the object representing the data that was submitted.

cbFnError (Function)
cbFnError (Function)This callback function is called if there is an error submitting the form's data. The function is passed a String parameter that contains any error information if available.The $zn.form.setStatusMessage function can be used to override the form's default error message.
