note 82160 added to tutorial.forms

I was so shocked that some servers have a problem regarding the Submit Type Name and gives a "Not Acceptable error" or Error 406. Consider the example below : <form action="blah.php" method="POST"> <table> <tr> <td>Name:</td> <td><input type="text" name="name"></td> </tr> <tr> <td colspan="2" align="center"> <input type="submit" name="Submit_btn" id="Submit_btn" value="Send"> </td> </tr> </table> </form> This very simple code triggers the "Not Acceptable Error" on PHP Version 5.2.5 and Apache 1.3.41 (Unix) Server. However to fix this below is the right code: <form action="blah.php" method="POST"> <table> <tr> <td>Name:</td> <td><input type="text" name="name"></td> </tr> <tr> <td colspan="2" align="center"> <input type="submit" name="Submitbtn" id="Submit_btn" value="Send"> </td> </tr> </table> </form> The only problem that took me hours to find out is the "_" in the Submit Button. Hope this help! ---- Server IP: 69.147.83.197 Probable Submitter: 203.177.57.170 ---- Manual Page -- http://www.php.net/manual/en/tutorial.forms.php Edit -- https://master.php.net/note/edit/82160 Del: integrated -- https://master.php.net/note/delete/82160/integrated Del: useless -- https://master.php.net/note/delete/82160/useless Del: bad code -- https://master.php.net/note/delete/82160/bad+code Del: spam -- https://master.php.net/note/delete/82160/spam Del: non-english -- https://master.php.net/note/delete/82160/non-english Del: in docs -- https://master.php.net/note/delete/82160/in+docs Del: other reasons-- https://master.php.net/note/delete/82160 Reject -- https://master.php.net/note/reject/82160 Search -- https://master.php.net/manage/user-notes.php
