Detecting Form Submit

[nummer31]

i'm working on a template and it has the following for submit button:

<a href="#" onclick="document.getElementById('contacts-form').submit()" class="button">send</a>

i'd like to know what is the 'getElementById' for and how do i detect that my form has been submitted? so that i can send the textfield values to the db.

The "getElementById" is to actually get the form and submit it once someone has clicked the button.

The other question you ask is a tad bit more complicated, javascript-wise you could use the "onsubmit"-function which is called once the form is, that's right, about to be submitted.

Otherwise if you're using PHP and the form has been submitted, you can use a ton of methods to verify someone has submitted something. For instance you can check if a field has been submitted by checking that $_REQUEST['fieldName']; (POST or GET should be used here instead of REQUEST) is set.
