Hi,

I have a form having id, action to url and post method. I have my html tags having ids. So are those enough that the target page will grab the values on those html tags via the ids' of those tags?

Regards.

For input controls to be posted back to the server from a form, you need to assign each relevant input control a name, not an id. id is used for Javascript to locate elements in the DOM, though name can be used for the same.

I'm not sure to understand this question: ids apart, if in the target you page use an appropriate php script to process form values, yes, your form contains data enough.
Wait, so 'name' is a must?

If you want the browser to send the data to the server...yes. That is, unless you are working some Javascript kung-fu into your page to submit the data programmatically.

I don't think you can count on 'id's being enough.  I use both 'name' and 'id' on all my tags in my HTML forms.  Javascript in particular likes the 'id's better.  It is difficult using the 'name' in javascript.

Yes, the 'name' is a must.  It becomes the array index into the request array, $_GET or $_POST.  This script illustrates the essential moving parts of an HTML form and a PHP action script.
