ukweb Posted May 29, 2006 Share Posted May 29, 2006 HiI'm making a registration system for a clients website. On the first page is a form with elements called 'email' and 'password'.On the following page if a username or password has not been set it should come up with a prompt for the username and password again, but it's not. Here is the bit of code I'm havin problems with;<?php if ( !isset( $_POST['email'] ) ) { ?>you did not specify a email address<?php } ?>I can;t see why its not working. If the username field is blank, surely it isnt set? or does the blank field being submitted class as being 'set'?Any suggestions around this?Many thanksSteve Quote Link to comment Share on other sites More sharing options...
samshel Posted May 29, 2006 Share Posted May 29, 2006 You are correct ..if it is blank it is not set..the problem might be somewhere else..can you please post the whole code ? Quote Link to comment Share on other sites More sharing options...
AndyB Posted May 29, 2006 Share Posted May 29, 2006 email might well be not set if your form asks for username and password. Is there more code we're not seeing? Quote Link to comment Share on other sites More sharing options...
kenrbnsn Posted May 29, 2006 Share Posted May 29, 2006 When a form is submitted, all text fields are set whether or not they are blank. In order to check that there is something in the value, you should check that the value is non-blank (or issue an error if it is blank).The following code illustrates this:[code]<?php if (isset($_POST['submit'])) echo '<pre>' . print_r($_POST,true) . '</pre>';?><html><head> <title>Test Form</title></head><body><?php$tmp = array();if (isset($_POST['submit'])) { if (!isset($_POST['username'])) $tmp[] = '<span style="font-weight:bold;color:red;">username</span> is not set'; if (!isset($_POST['password'])) $tmp[] = '<span style="font-weight:bold;color:red;">password</span> is not set'; if (!isset($_POST['email'])) $tmp[] = '<span style="font-weight:bold;color:red;">email</span> is not set'; foreach($_POST as $k=>$v) if ($k != 'submit') if (trim(stripslashes($v)) == '') $tmp[] = '<span style="font-weight:bold;color:blue;">' . $k . '</span> is blank'; if (!empty($tmp)) echo implode("<br>\n",$tmp)."<br>\n";}?><form method="post">Username: <input name="username" type="text"><br>Password: <input name="password" type="password"><br>Email: <input name="email" type="text"><br><input type="submit" name="submit" value="Test Form"></form></body></html>[/code]You can run this example at [a href=\"http://www.rbnsn.com/phpfreaks/test_form1.php\" target=\"_blank\"]http://www.rbnsn.com/phpfreaks/test_form1.php[/a]Whenever you have a question about what values are being returned to your script from a form, you should put the following code at the start of your script:[code]<?php if (isset($_POST['submit'])) echo '<pre>' . print_r($_POST,true) . '</pre>'; ?>[/code]This will show you the contents of the $_POST superglobal array formatted nicely.Ken Quote Link to comment Share on other sites More sharing options...
