I am working on a form that needs to valadate a field, If the field is not filled in then put the error on that page. not pop a warning box.

I know that j-a-v-a s-c-r-i-p-t does it, but it refreshes the page. DHTML does it as well and does not refresh the page..

This is off the top of my head and hand-typed, so probably won't work as is (and definitely needs the usual browser-compatible approach to getElementByID). But the principle is what you want, I think.

Apologies for the color coding; GFY doesn't respect the code tag like it does the php tag. And a few words tweaked to avoid hahahaha-age.

PHP Code:

<div id="errormsg"&nbsp;</div>
<for_m name=myform action="whatever" method="get">
hahahahahahaha type=text name="checkme">
hahahahahahaha type=submit value="Submit" onclick="if (documen_t.forms.myform.checkme = = 'bad') {documen_t.getElementByID('errormsg').innerHTML='You entered an invalid value'; return false;">
</form>

Cheers

A lot will depend on your form layout, but you could append an image tag whose source attribute is a blank gif/jpg and name attribute is identical to the name of the data field. As you loop through the datafields, each empty field can have the corresponding image source (using the images collection) changed to whatever icon you want, such as an exclamation point, etc. This will help identify the offending fields.

You can also replace or insert text, oriented in whcihever way to the offending fields, that states your specific error message, such as "First name is required.", etc.

To keep the elements from re-flowing when you add text/images, make room for them ahead of time. For example, make room for the input field and appended image tag in the table data tag, or add a blank table row (for the error messages) between each data field row. Style settings can then be used to format the presentation accordingly, such as error text in a smaller/larger font size/color, etc.

If any form field validation fails simply cancel the form submit action.
