note 80201 added to tutorial.forms

One thing that tripped me up when I was first learning PHP was the use of the NAME attribute in form fields. The current convention is to use the ID attribute instead when creating forms. (Many HTML editors automatically include an ID attribute without a NAME attribute.) Now, I include both the NAME and ID attributes (with the same value) in all my form fields. For example... <form method="post"> <input type="text" id="field1"> <input type="submit" value="go"> </form> If you then have a PHP page requesting the contents of the "field1" field... <?php echo $_POST["field1"] ?> ...the above form will always return an empty string for "field1". The solution is to include the NAME attribute... <form method="post"> <input type="text" id="field1" name="field1"> <input type="submit" value="go"> </form> With this change, the PHP code will correctly retrieve the value of the "field1" field. ---- Server IP: 209.41.74.194 Probable Submitter: 131.107.0.101 ---- Manual Page -- http://www.php.net/manual/en/tutorial.forms.php Edit -- https://master.php.net/note/edit/80201 Del: integrated -- https://master.php.net/note/delete/80201/integrated Del: useless -- https://master.php.net/note/delete/80201/useless Del: bad code -- https://master.php.net/note/delete/80201/bad+code Del: spam -- https://master.php.net/note/delete/80201/spam Del: non-english -- https://master.php.net/note/delete/80201/non-english Del: in docs -- https://master.php.net/note/delete/80201/in+docs Del: other reasons-- https://master.php.net/note/delete/80201 Reject -- https://master.php.net/note/reject/80201 Search -- https://master.php.net/manage/user-notes.php
