Form Submit where value = Next &rarr

[akrohn]

In a form example I am learning from I came across the value of the submit button being 'Next &rarr'. Could anyone explain this to me rather than using a value that sends you to another page to process the form? In this example what I am trying to learn is form validation using a function that checks for letters and numbers only.

Not sure if I really understand what your question is, but...

 

The value attribute of a button just controls what text is displayed in the button.  A value of 'Next →' would end up in a button with a label that looks like Next ->.

 

From the scripts point of view, the value of a button is fairly meaningless.  Usually you just check if a button was clicked by looking for it's name, eg:

if (isset($_POST['btnNext'])){

would test if the next button was pressed, assuming you have name="btnNext" in your HTML code.
