Hi i have a html form with an input file and many more fields .I am going to validate it by jquery form validator plugin . It works like a charm for text inputs and selects but it just validate file input when it is empty. When I choose a file in any wrong type or wrong size , even if I didn't filled other required text input , it submit the form in GET method.this is my jquery code:
$("#form").validate({
ignore: 'input[type=hidden], .select2-search__field', // ignore hidden fields
errorClass: 'validation-error-label',
successClass: 'validation-valid-label',
highlight: function (element, errorClass) {
$(element).removeClass(errorClass);
},
unhighlight: function (element, errorClass) {
$(element).removeClass(errorClass);
},
// Different components require proper error label placement
errorPlacement: function (error, element) {
// Styled checkboxes, radios, bootstrap switch
if (element.parents('div').hasClass("checker") || element.parents('div').hasClass("choice") || element.parent().hasClass('bootstrap-switch-container')) {
if (element.parents('label').hasClass('checkbox-inline') || element.parents('label').hasClass('radio-inline')) {
error.appendTo(element.parent().parent().parent().parent());
} else {
error.appendTo(element.parent().parent().parent().parent().parent());
}
}
// Unstyled checkboxes, radios
else if (element.parents('div').hasClass('checkbox') || element.parents('div').hasClass('radio')) {
error.appendTo(element.parent().parent().parent());
}
// Input with icons and Select2
else if (element.parents('div').hasClass('has-feedback') || element.hasClass('select2-hidden-accessible')) {
error.appendTo(element.parent());
}
// Inline checkboxes, radios
else if (element.parents('label').hasClass('checkbox-inline') || element.parents('label').hasClass('radio-inline')) {
error.appendTo(element.parent().parent());
}
// Input group, styled file input
else if (element.parent().hasClass('uploader') || element.parents().hasClass('input-group')) {
error.appendTo(element.parent().parent());
}
// Inline checkboxes, radios
// else if (element.parents().hasClass('uploader')) {
// error.appendTo(element.parent().parent().parent().parent());
// }
else {
error.insertAfter(element);
}
},

after deep searching i found what is the problem. To validate extensions with jquery validation plugin you must include additional_methods.js file.it must be added after validate.js file. Hope it help you.
