Form Sending Blank Emails After Validation?

Jul 13, 2010

I have a couple of forms which use JS validation and if the validation checks out the forms action is a new php page which sends the form (see code below). It all works fine but occasionally blank emails come through. After researching some people say I shouldn't use client side validation. Is there an easier way by tweaking the code I have rather than changing it all completely?

<script language="php">
$email = $HTTP_POST_VARS[email];
$mailto = "info@xxxxxxxx.com";
$mailsubj = "mail form";

[Code].....

Validate A Web Form - Sending Email Alerts With Every Field Blank

Jul 13, 2011

I am trying to validate a web form. Someone else wrote the Html code and implemented it with an iframe using asp and php. I didn't want to mess too much with the code so I decided to use javascript to make the form validate, before it was sending email alerts with every field blank. For the most part the validation works but it skips the email field for some reasons and is really bugging me to death. this is the code:

<head>
<link type="text/css" rel="stylesheet" href="CSS/style.css"/>
<title>Bid Form</title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<script src="gen_validatorv4.js" type="text/javascript"></script>
<script type="text/javascript">

CSS And Form Validation - Changing The Font Color Of Labels ONLY When Stop The Form From Submitting Due To Blank Fields

Nov 2, 2011

I'm having trouble changing the font color of my labels ONLY when I stop the form from submitting due to blank fields. I'm not sure whether if just changing my CSS will achieve what I want, or am I going to have to add somethig to my if else statement, or both? I would think I would need to change CSS to :

label.onfocus {
color:red;
}

but a little confused on what else.

Jquery :: Ajax Validation - How To Blank Out Field In Form

Feb 28, 2011

I have a scenario where I have the following jquery
Code:
$("#frompdc<?php echo $JavaCnt;?>").change(function(){
var id = $('#id<?php echo $JavaCnt;?>').attr('value');
var frompdc = $('#frompdc<?php echo $JavaCnt;?>').attr('value');
var topdc = $('#topdc<?php echo $JavaCnt;?>').attr('value');
$.ajax({
type: "POST",
url: "AJ_Update.php",
data: "firm=y&id="+ id + "&frompdc=" + frompdc&topdc=" + topdc
});

And some php to insert this data
Code:
mysql_query("UPDATE TBLTRANSFERS SET FROMPDC = ".$_POST['frompdc'].", MOD_TS = '". $timenow ."' WHERE ID = ".$_POST['id']);

I'm trying to throw some validation in here which I can do in php (a language that I'm much more proficient in) but can't figure out how to get the two together. I want to be able to do a select against another table I have for both the frompdc and the topdc.
Code:
$tofpdcresult = mysql_query("SELECT * FROM tbltransferspdcexclusions where FROMPDC = '".$frompdc."' AND TOPDC = '".$topdc."'");
$tofpdcnum_rows = mysql_num_rows($tofpdcresult);
And if it exists I want to give a popup message to the user as well as blank out the field.

I'm struggling with two things:
How do I get ajax to run two queries and return the results to a popup window?
How do I blank out the field in the form?

Form Validation Before Sending To PHP Script?

Mar 29, 2010

I'm having trouble validating a form with javascript before sending it to a php script. Even when the form fails validation it still sends to the php. I believe it's to do with my validation script. You can see the script live here: [URL]

HTML Form:
Code HTML4Strict:
<form action="includes/verify_login.php" onsubmit="return validate_login(this);" method="post" name="login_form">
<label for="user">Username</label><input type="text" class="custom_field" name="user" id="user">
<label for="pass">Password</label><input type="password" class="custom_field" name="pass" id="pass">
<input type="checkbox" id="remember" name="remember"><label id="label_remember" for="remember">Remember Me</label><br>
<button id="custom_button">Login</button>
</form>

Javascript:
Code JavaScript:
function validate_required(field){
with(field){
if (value==null||value==""){
document.getElementById("empty").style.display="block";
return false;
}else{
return true;
}}}
 
function validate_login(thisform){
with (thisform){
if (validate_required(user)==false){
name.focus();
return false;
}else if (validate_required(pass)==false){
comment.focus();
return false;
}else{
return true;
}}}

Form Validation - Should Return Message Like "should Not Be Empty" When User Leaves Field Blank

Oct 8, 2010

I want to do a form validation and it should return a message like "should not be empty" when the user leaves the field blank..

I have html code like this

Now I want to know how can i display alert message to the user saying that the particular label name should not be empty..

For eg.. here I want to display alert as "Did you find this article useful? field should not be empty".... (Assuming this is mandatory)

I have so many fields like this in my form(checkbox, radio buttons, etc...) and i want to display alert with label name...

How can I do this using javascript.. (I know how to do validation in javascript popping up the alert(without label name), But I am not sure how to display alert with label name))))

Blank Field Validation Ignored By FF And IE?

Mar 11, 2011

I have a three field contact form on an HTML5 page. Using CSS3/HTML5 techniques, the fields change state as the info is entered properly (green OK symbol if good, red "!" if not, etc). That all works as expected in all browsers.

My final hurdle is preventing the form being submitted with nothing entered in the fields. I have done hours of research and have tried several ways of writing the checkFeedbackForm function. My problem is that none of the solutions I've found are recognized by FireFox (mac and pc) and IE. They just ignore the javascript and allow the empty form to be emailed.

The File Input Goes Blank When Trying To Submit Form?

Dec 21, 2010

I have one document that resides in an iFrame, and it contains anywhere from 1 to 4 forms, depending. There is a dynamic content area that will display between zero and three forms, each named uniquely, associated with files that exist in a database. Regardless of the number of forms associated with a file, at the bottom of the document is one last form named NewDoc - this last form is used for uploading a new file into the database, or replacing a file.With one exception, this is working flawlessly.The user is supposed to choose a file for upload, use a SELECT input to say what document type it is, then click on the submit button.

What is actually happening, however, has me confuzzed. When the submit button is clicked the first time, the value of the input="file" element becomes blank and nothing happens. If a file is chosen, again, and the submit button clicked, it uploads with no problem and the database does what it's supposed to. But if I refresh the document and try, again, same thing - the file disappears from the form element and the form does not submit.First, the forms (all three, just in case):

Code:
<form name="updateDocs_1" id="updateDocs_1" method="post" style="margin:0px; padding:0px; border:0px;"
action="supplier_docs.cfm?vid=122" enctype="multipart/form-data">

How To Eliminate Blank Spaces Between Elements In A Dynamic Web Form

Sep 22, 2004

I am designing a dynamic web form, and all works fine except that I can’ t eliminate the ‘blank’ spaces that appears between the form elements when these are displayed or hidden. I mean for example, the long blank space that appears between the form submit button and the table rows displayed, because the other tables and form elements are hidden.

I attached the complete sample page so that you can see the ‘blank’ spaces I want to eliminate. These are the 'blank' spaces I want to eliminate:

1. When the page loads, a long blank space appears between the submit button and the table rows displayed.
2. When you select only the ‘Quality B’ checkbox, a long blank space appears between the ‘Product details’ title and the table rows displayed.
3. When you select both ‘Quality A’ and ‘Quality B’ checkboxes, a blank space appears between the table rows displayed. I want a blank space there, but smaller.

In all the cases I want the submit button just below (with a little blank space) the table rows displayed.

Dialogue / Input Box That Enables Right-Click & Emails Info

May 21, 2010

Way back in the day I did some old school HTML....but after many years not touching a web page I've kind of been thrown straight into the fire with some "wish list" items I'm trying to figure out. I've done plenty of searches and somewhat have an understanding of some of the basics of what I need to do...but I'm not the least bit comfortable with Javascript (I'm just assuming that this the language most applicable to what I'm looking for - and after the experience of my one day crash course with PHP I knew I needed to turn to some experts.

Okay I have a rather large web (about 150 pages) of historical transcriptions created with XHTML (with PHP headers and footers embedded). Generally speaking, I don't much like web pages that have right-click disabled and various other protections in place.....but I'm also the sort to obsessively cite my source material and give proper credits....as a researcher who's hard work has been plagiarized and passed off as the fruits of someone else's labor, I wholly understand why many are inclined to put such walls up.

Form Sending Twice

Jul 23, 2005

I have a form that calls a perl script. A few javascript routines in
the form do a few things prior to submitting. For some reason,
however, the perl script is being called twice (the perl script sends
out an email, and submitting the form once results in two identical
emails.)

Here are excerpts from the script that I believe to be relevant (I can
post more if this isn't enough, but it's long and I'm trying to keep
it brief.) Can anyone tell me what I'm doing wrong? I've read about
how you need to return true after calling the javascript via a button
click, but I've done this kind of thing in other places and it's
worked fine. I've also tried inserting a return statement here in the
function and it doesn't seem to make a difference. Strange. (BTW, I
changed the domain name in the URL out of courtesy to my client, just
FYI.) Code:

JQuery :: Validation: Form With Multiple Submit Buttons Having Different Validation Rules

I have a form with multiple fieldsets which are visible conditionally. There are three submit buttons "Abandon", "Save" and "Save & Continue". Each button should validate specific controls of the form and submit it. I tried setting "onsubmit: false" and checking for "$('#myForm').valid ()" on click of these buttons., but that validates all controls of the form.

JQuery :: Validation Plugin - Submit Form Without Validation?

Jul 19, 2009

I'm using the Validation plugin for JQuery and was wondering if there was a function to submit the form without causing it to validate the form. I have a table with a list of radio-buttons and above that is a drop down list of states. The drop down list of states is used to filter the table rows and when the selected item changes it posts-back to the server (via $("#frm").submit()). I don't want this to cause any validation to occur. Is there another function I can call besides submit(), or some other method?
