I'm Stuck

[refiking]

I want to check the values from a form to see if the user accidentally missed one of the fields.  If they did, I want to show the form again.  Here's what I have so far.  As of right now, the form does not get displayed again if there is an error on the user's part.

 

$season = $_POST['season'];
$month = $_POST['month'];
$day = $_POST['day'];
$year = $_POST['year'];
$hour = $_POST['hour'];
$min = $_POST['min'];
$apm = $_POST['apm'];
IF ($month == "Month"){
$month = "";
}
IF ($day == "Day"){
$day = "";
}
IF ($year == "Year"){
$year = "";
}
IF ($hour == "Hour"){
$hour = "";
}
IF ($min == "Minute"){
$min = "";
}
include 'cont.php';
if(!isset($season) | !isset($month) | !isset($day) | !isset($year) | !isset($hour) | !isset($min)) {

Well, first off, try to make the subject a bit more... useful, not just "i need help" or "im stuck"

 

onto the code... you are missing an if statement for 'apm' and try using the following code as the last line:

 

if(!isset("$season") | !isset("$month") | !isset("$day") | !isset("$year") | !isset("$hour") | !isset("$min")) {

 

not sure why, but sometimes things like that dont make sense (to me anyways..) but make code work..

What you should do is hold your form in a variable

<?php
$form = "<form name=\"formname\" method=\"POST\" action=\"somepage.php\">
<input name=\"somename\" type=\"text\" value=\"".@$_POST['somename']."\" >"; // will put the value of the field if it has been submitted
// continue on

 

Then the page that checks for empty fields

<?php
$error = "";
forech($_POST as $key => $val){
  if(empty($key)){
  $error = "$key, ";
  }
}

if($error != ""){
echo "The following fields need to be fixed: $error<br>";
echo $form;
} else {
// process the form 

}
?>

 

Granted this can be expanded upon but just to give you a very simple idea
