How To Support Multiple Submit Buttons in PHP?
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.
