Check If Form Element Exist in Page
Here is my form:
<form name="FormXX" method="post" action="default.htm">
<input id="idBoxOne" name="bxOne" type="text">
</form>
I know how to get the value of an input button.
var text = document.FormXX.bxOne.valu
How do I write an if statement to check if the form value of bxOne exist or not?

By the way .. that is Javascript, which is what you were using in the code you had for the example. You posted this in the PHP zone though so if you need this on the server in PHP then use ...
if (isset($_POST["bxOne"])) {
// the browser sent something for this field
} else {
// nothing was in this field
}
Let me know if you have a question.
