View Full Version : Displaying error msgs in forms

Hello

I have a form with JavaScript validation. If the name is missing, or the email (etc), an error message appears to say: 'Please type your name', or 'Please type your email', etc. Unfortunately, these error messages appear on the same line at the top of the form, rather than on a line above each field. What this means is that if the site visitor fails to put in a name, email address, and message, the above error occurs at the top of the form: 'Please type your name Please type your email Please type your message'.

What is the best way of solving this untidyness? To have the error display a message above each of the individual form fields? Are there any online examples or does anyone have alternate ideas?

Thanks.

Steve

Thank for any help you cagive, abduraooft.

Here is the JS file that seems to govern the form:


$(document).ready(function () {
$('#contact-form input.contact, #contact-form a.contact').click(function (e) {
e.preventDefault();
// load the contact form using ajax
$.get("data/contact.php", function(data){
// create a modal dialog with the data
$(data).modal({
closeHTML: "<a href='#' title='Close' class='modal-close'>x</a>",
position: ["15%",],
overlayId: 'contact-overlay',
containerId: 'contact-container',
onOpen: contact.open,
onShow: contact.show,
onClose: contact.close
});
});
});




// preload images
var img = ['cancel.png', 'form_bottom.gif', 'form_top.gif', 'loading.gif', 'send.png'];
$(img).each(function () {
var i = new Image();
i.src = 'img/contact/' + this;
});
});


var contact = {
message: null,
open: function (dialog) {
// add padding to the buttons in firefox/mozilla
if ($.browser.mozilla) {
$('#contact-container .contact-button').css({
'padding-bottom': '2px'
});
}
// input field font size
if ($.browser.safari) {
$('#contact-container .contact-input').css({
'font-size': '.9em'
});
}

// dynamically determine height
var h = 280;
if ($('#contact-subject').length) {
h += 26;
}
if ($('#contact-cc').length) {
h += 22;
}

new AjaxUpload('#documents', {
//action: 'upload.php',
action: 'upload.php', // I disabled uploads in this example for security reaaons
name: 'myfile',
responseType: 'json',
onSubmit: function(file, extension) {
$("#loader").css('display','block');


},
onComplete : function(file,json){

if(json.error=='No error')
{
$('#documents').css('display','none');
$('#documentsname').val(json.filename);

You will need to click the 'Contact' tab to see the form.
