gsingh85 Posted December 30, 2013 Share Posted December 30, 2013 (edited) I have a simple newsletter sign up script that I'm using. I built it using a tutorial and because it's simple and basic I'm able to tweak it here and there as and when I need to. There are some messages such as "?? is already on the system" and "please enter an email address". All these work fine however when I display certain messages such as "is already on the sytem" or "you have been added sucessfully" I want the text boxes to disappear. I've been looking online and I haven't found anything which is most likely because I don't know the correct terminology of what I'm looking to do. I only what the boxes to dissappear when certain messages are display. Can someone please help me with this or direct me to a tutorial. Here is the script: <?php $name = ""; $email = ""; $msg_to_user = ""; if (isset($_POST['name']) && $_POST['name'] != "") { include_once "connect_to_mysql.php"; // Be sure to filter this data to deter SQL injection, filter before querying database $name = $_POST['name']; $email = $_POST['email']; $sql = mysql_query("SELECT * FROM newsletter WHERE email='$email'"); $numRows = mysql_num_rows($sql); if (!$email) { $msg_to_user = '<br /><br /><h4 class="header">Please type an email address ' . $name . '.</h4>'; } else if(!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$email)) { $msg_to_user = '<br /><br /><h4><font color="FF0000">invalid email address.</font></h4>'; } else if ($numRows > 0) { $msg_to_user = '<br /><br /><h4><font color="FF0000">' . $email . ' is already in the system.</font></h4>'; } else { $sql_insert = mysql_query("INSERT INTO newsletter (name, email, dateTime) VALUES('$name','$email',now() )") or die (mysql_error()); $msg_to_user = '<br /><br /><h4>Thanks ' . $name . ', you have been added successfully.</h4>'; $name = ""; $email = ""; } } ?> </div> <html> <head> <style> .header { color:#D2691E; background-color: #000000; } </style> <title>Subscribe to Our Newsletter</title> </head> <body> <form style="width:440px;" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> <fieldset style="text-align:left; padding:24px;"> <legend>Subscribe to Our Newsletter </legend> <br /> Name:<br /> <input name="name" type="text" maxlength="36" value="<?php echo $name; ?>" /><br /> Email:<br /> <input name="email" type="text" maxlength="36" value="<?php echo $email; ?>" /><br /><br /> <input name="mySubmitBtn" type="submit" value="Submit"> <?php echo $msg_to_user; ?> </fieldset> </form> </body> </html> By the way I tried: ****************************************************************************************************************************** <body><form style="width:440px;" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"><fieldset style="text-align:left; padding:24px;"><legend>Subscribe to Our Newsletter </legend><br /><?php if($msg_to_user !=''){ ?> Name:<br /><input name="name" type="text" maxlength="36" value="<?php echo $name; ?>" /><br />Email:<br /><input name="email" type="text" maxlength="36" value="<?php echo $email; ?>" /><br /><br /><input name="mySubmitBtn" type="submit" value="Submit"><?php } ?> <?php echo $msg_to_user; ?></fieldset></form></body> ****************************************************************************************************************************** but it doesn't work. All that happens is when the page loads up the sign up boxes are not there. Any help will be much appreciated as I've been trying to find a solution for this over the last 3 days. Thanks in advance.

hansford Posted January 6, 2014 Share Posted January 6, 2014 $msg_to_user = ""; When the page is first loaded, this variable remains empty. On the second page load, this variable gets set - or should. Thus we should be checking not for: <?php if($msg_to_user !=''){ ?> but for: <?php if($msg_to_user == ''){ ?> which would insert the name and address boxes into the form. You can also set flags (variables of either true of false) for each section of code and then check that value before displaying that particular html section.
