Hello all,
I am very new to coding and even newer to Javascript. My brain works by thinking in general/abstract all the time and I am lazy, so I hate doing anything remotely repetitious. In that vein, I wrote this script to chuck through a form, any form and check for nulls where there shouldn't be. I used alerts to notify, but you could just as easily add a red error tag and focus() back. All you have to do is add informative and readable titles to fields you want null-validated. And add this to your onsubmit="retur n validation();" line. All hidden or button or submit, etc. inputs are ignored if you don't add a title to them. - function nullValidation() {
-
var x = document.getElementById("myForm");
-
-
for (var i = 0; i < x.length; i++) {
-
if(x.elements[i].value == "" && x.elements[i].title) {
-
alert("Please enter or select " + x.elements[i].title + ".");
-
x.elements[i].focus();
-
return false;
-
}
-
}
-
-
return true;
-
}
-
again, i am not a coder, but this simple script has saved me much, much time on new site i am building with about 20 different forms on it for getting/updating data to mysql.
regards,

Thanks for sharing!
I've moved this to the Articles section, since it's not a problem, but a solution.
I've added code tags for you (makes it much easier to read).
thanks it really saves a lot of time in formvalidation.
Thank you
Yes, thanks for sharing, it does save a lot of time compared to what I had
Glad to help! I am King of generic.
Here was another time saver for PHP/MySQL:
If you ever get form submission which needs to update multiple fields in multiple tables like in a user profile, use this script that finds any fields that have changed, and then rips through to MySQL and UPDATES only those fields. I wrote this to go one field at a time, no compound UPDATE statements, since the hassle of gathering all fields from one table would cut down on SQL queries, but got complex on PHP side.
I use this PHP as an object method (one in account.class.p hp and one in user.class.php) , so admins, users, FBI, NSA, anyone who wants to can use it. http://www.thescripts.com/forum/thread666660.html

I want the server-side php script to return a browser page that is essentially a copy of the
original client page that contained the <form> which referenced the php script in the first place.
However, the php script will need to change a couple html lines in that returned page. I sure could
you some help on how to go about this.
Thanks in advance,

I have some old code that I use from the Access 95 Developers handbook. The
code works very well, with the exception that it doesn't seem to recognize
wide screens, and sizes tab controls so that they are too big and wind up
covering up some of the fields on the main form.
Is there any good code out there that works in a similar fashion that will
also either a) stretch the form width wise on widescreens or b), rely on
height rather than...

Hi,
I have been looking around the forum and the web for a way to achieve this and so far I have drawn a blank. So I head to the forum as I'm sure someone knows how to do this.
I have a form which I validate as the user enters data, this is straight forward enough. Part of the validation ensures that all mandatory fields are entered before the continue button is enabled.
(unfortunately this is a development site at present and so I can't...

Introduction
Many websites have a form or a link you can use to download a file. You click a form button or click on a link and after a moment or two a file download dialog box pops-up in your web browser and prompts you for some instructions, such as “open” or “save“. I’m going to show you how to do that using a perl script.
