Peter, Bob,

Thank you for replying.
After a few days testing, I set up an error handler for when messages don't get sent. I started to see an error saying "Language String failed to load", which seems to be particular to the PHPmailer scripts I am using.
Long story short, after some searching on the web, it looks like the sending of mails will die if one mail on the list is invalid.
I tried sending a message out to the list, got back a response saying that the recipient did not exist. So I deleted that user, and then the mail went through fine on the next attempt. 

I'm a little fuzzy on what exactly is happening.
Does the PHP mail() command (and by extension, classes built upon it) listen for responses from the server it is sending to?

Yep, that's no big deal.  A webserver is just some code that listens for
requests on port XX, processes the requests and sends back suitably
formatted responses.

Hi.

Can't seem to see a way to do this.

Is there a way to do this?

If you want to prevent certain extensions then just flirt then out from the 
$_FILES array before you copy them out of the temp directory, as that is where 
they should be uploaded ready for your script to process.

Thanks,

Are you talking about a PHP extension or a file extension?

Hey everyone!
Hope you are having a great weekend, and I'm hoping someone might be coherent enough to help me find a more elegant solution to a problem that I have...
I have a form for submitting an event to a website, and if the form is not submitted successfully (such as they didn't fill out a required field) I want it to redisplay the form with inline errors as to what happened and display the values they selected...
I have a working solution but was hoping for something a little more elegant. And something that would work better for a month selector as well... Here is the relevant code that I have that works: 

<?PHP
        if ($_POST['hidSubmit'] ==TRUE & $_POST['type'] == "meeting"):
echo <<<HTML
        <select name="type" id="type">
            <option value="0">-- select type --</option>
            <option value="meeting" selected>Meeting</option>
            <option value="event" >Event</option>
        </select>
HTML;

elseif ($_POST['hidSubmit'] == TRUE & $_POST['type'] == "event"):
//if ($_POST['hidSubmit'] == TRUE & $_POST['type'] == "event") {

echo <<<HTML
        <select name="type" id="type">
            <option value="0">-- select type --</option>
            <option value="meeting">Meeting</option>
            <option value="event" selected>Event</option>
        </select>
HTML;

else:
//if ($_POST['hidSubmit'] != TRUE):


echo <<<HTML
        <select name="type" id="type">
            <option value="0" selected>-- select type --</option>
            <option value="meeting">Meeting</option>
            <option value="event">Event</option>
        </select>
HTML;
endif;

?>
which works BUT I don't want to have to have that for a month selector or a day selector :) 

Any ideas what I'm missing?

For a month selector, using a loop to output the months is good, as you can 
then within the loop check for that value sent and set the selected html 
attribute for that select element.

I should warn you that your code will throw a warning when no data has been 
posted to it. Consider using isset() instead to check for posted values rather 
than comparing a value (which might not exist) with true.

Thanks,

Jason:
I think what you are missing is that this data collection should be split between client-side and server-side operations.
For client-side simply use javascript to monitor what they user enters and then immediately respond to the requirements imposed upon the user.
After the user fills out the information correctly and clicks submit, then have your server-side scripts check the data again and respond accordingly. 

Here are a couple of examples:

Rather than repeating all that code, I suggest the following:


<select name="type" id="type>
   <option value="0">-- select type --</option>
<option value="meeting" <?php echo (isset($_POST['hidSubmit'] && $_POST['hidSubmit'] == TRUE && $_POST['type'] == "meeting") ? "selected" : '' ?> <option value="event" <?php echo (isset($_POST['hidSubmit'] && $_POST['hidSubmit'] == TRUE && $_POST['type'] == "event") ? "selected" : '' ?> 
</select>


For a month selector, try:

<?php
   // assume current month number is in $curr_month
$months = array(1 => "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"); // will create an array of month names, with a starting base of 1 (instead of zero) 

  echo "<select name=\"month\" id=\"month\">\n";
  foreach ($months as $m => $mname) {
    echo "<option value=\"$m\"";
    if ($curr_month == $m) echo " selected ";
    echo ">$mname</option>\n";
  }
  echo "</select>\n";
?>
There are other possiblities as well. One time, I didn't want to actually store the month names, perhaps allowing them to be localized. Instead I used strftime, which will return appropriate names based on locale: 

<?php
  // assume current month number is in $curr_month

  echo "<select name=\"month\" id=\"month\">\n";
  for ($m = 1; $m <= 12; $m++) {
    echo "<option value=\"$m\"";
    if ($curr_month == $m) echo " selected ";
    echo ">";
$mname = strftime("%B", 0,0,0,2010, $m, 1); // time, year and day don't matter, all we're after is the appropriate month name set in the locale 
    echo $mname;
    echo "</option>\n";
  }
  echo "</select>\n";
?>

--- Begin Message --- The debate on client-side vs. server-side form validation is ongoing. Client-side is more responsive, and attempts to keep bad data from ever reaching your application, but relies on javascript being enabled. Since this is something easily turned off by users, one can't always rely on it to do form validation. So server-side validation is needed as well to allow your full application to gracefully degrade in the absence of working javascript on the client's side. Coding defensively helps!

I have a general question and am looking for best practices.
Suppose I present a user with a form for editing an entry in a table, i.e., the form has filled in values from the existing table entry.
Now, suppose they click on 'submit' without making any changes in the form. (Perhaps, say, rather than clicking 'Cancel' or 'Return to Main' or some other option which would get them out of that screen without submitting the form).
Is it worth the overhead of passing along the previous values in the table in hidden fields so that fields can be checked to see if they've been updated or not after the submit? Or is it worth reloading the old values from the table to check against the newly submitted form? Or is all that overhead not worth the time because an update that overwrites existing values with the same values is not that onerous? 

(Is that question clear enough?)
