Sometimes, you may need to give visitors multiple submit buttons on a single form to allow
them to submit the form for different purposes. For example, when you show your customer a purchase order
in a Web form, you may give your customer 3 submit buttons as "Save", "Copy", and "Delete".
You can do this by adding "name" and "value" attributes to the <INPUT TYPE=submit ...> tags to
differentiate the buttons. The following PHP script is a modified version of submit_comments.php
with 3 submit buttons:
<?php
$comment = 'I want to say: "It\'s a good site! :->"';
$comment = htmlspecialchars($comment);
print("<html><form action=processing_forms.php method=post>");
print("<table><tr><td colspan=2>Please enter and submit your"
." comments about FYICenter.com:</td></tr>");
print("<tr><td>Your Name:</td>"
."<td><input type=text name=name></td></tr>\n");
print("<tr><td>Comments:</td>"
."<td><input type=text name=comment value=\"$comment\" size=40>"
."</td></tr>\n");
print("<tr><td colspan=2>"
.'<input type=submit name=submit value="Submit now">'
.'<input type=submit name=submit value="Save only">'
.'<input type=submit name=submit value="Cancel">'
."<td></tr></table>\n");
print("</form></html>\n");
?>
If you view this PHP page, you will see 3 buttons. If submit the form by clicking the "Save only" button,
you will get something like this:
Number of values: 3
name = Peter
comment = I want to say: "It's a good site! :->"
submit = Save only
Obviously, different code logics should be written based on the received value of the "submit" field.
