Form is submitted twice - BootstrapValidator

By default, after pressing the submit button, the plugin will validate fields and then submit the form if all fields are valid.

If you use a custom submit handler, the form might be submitted more than one time.

To prevent the plugin from submitting the form automatically, you can trigger the success.form.bv event:

$(document).ready(function() {
    $(form)
        .bootstrapValidator({
            ... options ...
        })
        .on('success.form.bv', function(e) {
            // Prevent form submission
            e.preventDefault();
            // You can get the form instance
            var $form = $(e.target);
            // and the BootstrapValidator instance
            var bv = $form.data('bootstrapValidator');
            // Do whatever you want here ...
            // Use the defaultSubmit() method if you want to submit the form
            // See http://bootstrapvalidator.com/api/#default-submit
            bv.defaultSubmit();
        });
});

You can use a custom submit handler like the following way:

$(document).ready(function() {
    $(form)
        .bootstrapValidator({
            ... options ...
        })
        .on('success.form.bv', function(e) {
            // Prevent form submission
            e.preventDefault();
        });
    // Custom submit handler
    $(form).submit(function(e) {
        // You can get the form instance
        var $form = $(e.target);
        // and the BootstrapValidator instance
        var bv = $form.data('bootstrapValidator');
        // Do whatever you want here ...
    });
});
