HI there I have two drop down boxes. One to select the time and another to select the price of an event.

Basically I want them to be sticky so if the form is submitted and there is a mistake I want the form to remeber the value.

I've included two parts to my script the

the drop down boxes:

Event start time:<select name="eventtime">
 
<option value="00:00:00">00:00</option>
<option value="00:30:00">00:30</option>

if (!empty($_POST['eventtime'])) {

} else {

 

  $etm = NULL;

  echo '<p><font color="red" size="+1">Please enter a time for the event.</font></p>';

  

}

 

// Check for entry price

 

if (!empty($_POST['eventprice'])) {

  $epr = escape_data($_POST['eventprice']);

 

} else {

 

  $epr = NULL;

  echo '<p><font color="red" size="+1">Please enter a price for the event.</font></p>';

Hi afzz,

The code above brings about an error. The error says that $epr and $etm are undefined variables.

It may need an if (isset($_POST['eventdate'] sort of clause?

Thanks in advance!

at the top of your script initialize the variables as shown below and try

$etm = "";
$epr = "";

HI afzz,

it still says there is an error in defining the variables :(

This is how I defined the variables

// Check for event time

if (!empty($_POST['eventtime'])) {
  $etm = escape_data($_POST['eventtime']);

} else {

$etm = "";

  echo '<p><font color="red" size="+1">Please enter a time for the event.</font></p>';
 
}

// Check for entry price

if (!empty($_POST['eventprice'])) {
  $epr = escape_data($_POST['eventprice']);

} else {

$epr = "";
  echo '<p><font color="red" size="+1">Please enter a price for the event.</font></p>';
 
}

The code if (!empty($_POST['eventtime'])) { is within a condition. That is only if there has been a post to the script this is initialized

your code above will not initialize the variables unless there is a post action to the script.

Therefore above everything else add this.

$etm = "";
$epr = "";
and after that add

if (!empty($_POST['eventtime'])) {
......

Hi Afzz,

It is still coming up with the same error even though I set the variables above the condition : s.

Thanks again,
