I need any user to submit a form and dont show it to anyone else after being submitted

There was an error in my last post, please find proper code below!!


you could write your data to a text file on the server, so that the solution is independant of any sessions for example.  You should make sure that you have the proper write/execute permissions on the server.  If you prefer, instead of posting form data to $_SERVER[PHP_SELF], you could post form data to a file in a section of your server that is not accessable from the web, this will remove any dangers of setting write permissions to web accessible folders.

in your section for handling the sms sending, you need to add the following code prior to the sms sending, which will write a small text file in the same directory as the script.  By writing the data in a php format, we can use it later if you want to make your script more advanced (reset button?)

<?php
$your_data = "$smssent=1";
// Open the file and erase the contents if any
$fp = fopen("smssent.php", "w");
// Write the data to the file
fwrite($fp, $your_data);
// Close the file
fclose($fp);
?>

You then need to use the following code on your main error page, which will decide whether or not to show your form, based on whether or not the file exists.  If you want to add reset scripts etc, you can always check the data that is held in the "$smssent" variable instead.

<?php
$filename='smssent.php';

if (file_exists($filename)) {
   //Nothing needs to be done, we don't want to show the form
}
else {
echo "<form method='POST' action='$PHP_SELF'>
Number:<br />
<input type='text' name='number' maxlength='10' class='inputbox'><br />
(Example: 8001234567; US Only)<br /><br />
Subject:<br />
<input type='text' name='subject' maxlength='20' class='inputbox'><br />
(Max 20 Characters)<br /><br />
Message:<br />
<textarea name='message' rows='10' cols='15' class='inputbox'></textarea><br />
(Between 3 - 120 Characters)<br /><br />
<input type='submit' name='do' value='Send' class='button'>
</form>";
}
?>
