## Validate Many Input Fields Inside A Form?

May 6, 2011

So I am trying to validate many input fields inside a form before I send it off to mysql.

I am 99% sure it a JavaScript issue and I am a beginner with JS. My JS code is as follows:

function validate(form)
{
//Pull values from form
var email = form.user_email.value;
var confEmail = form.conf_email.value;

[Code]....

I'm trying to change the color of the labels according to what input field is wrong. It seems to loop through and keep my labels black. It shows the email red for a millisecond though.

## Swap Form Input Fields Contents?

Feb 27, 2007

I have one form on a page with 'n' text input fields grouped in blocks of the same input fields. Something like this:

<div id="block1">
name_1
lastname_1
phone_1
...
</div>
<div id="block2">
name_2
lastname_2
phone_2
...
</div>
...

The number of fields for each block varies because the page is constructed by a server function. What I want to implement is move up and a move down buttons on each block to move what the user has entered in say, block 4, to block 3 (and move the block 3 contents to block 4). And the contrary too.

## Disable / Lock Text Input Form Fields

Sep 29, 2007

I've created a admin center, that has two seperate login permissions. Admin which can edit listings, etc... and Viewer which can only view listings, and edit 1 or 2 of the listings details and not all of them like the admin. I've seen web-sites where certain text input fields are sort of Grayed out, not allowing for user to type, click in or change anything in that field. Sort of like the html text input field has been or is disabled. How can I get certain html text input fields to appear disabled, and the text that's inside un-editable or unchange-able?

I have a form that collects information about up to 5 items. I would

fields for only 3 items are shown, if they change it to 4 items, then a
fourth column shows up in the table with the appropriate input fields.
