Variables not passing from page to page

woodsonoversoul · December 17, 2008

Hi all,

I've got a multi-file, mp3 upload system that works (kinda) like this - there are two pages, one takes in information about the group of files ( band, date, etc.) and also the song names, separated by a comma. This page then passes this information to the actual uploading page which displays the file group information and also creates an upload box for each one of the songs listed on the previous page. There is one submit button, which, when pressed causes the page to call itself and upload the files. Most of this works all well and good, that is, until the page calls itself. When the page calls itself, it uploads the files fine, but doesn't pass any other variables (band, date, etc.) I've tried to solve this by echoing out hidden inputs in the html section, but no luck. Here's the code from the page that calls itself (the upload page). Anyone else see anything?

Your solution would work but you placed the hidden form element outside of the form tags.

Thanks flyhoney! works great now

woodsonoversoul · December 18, 2008

Well actually it was working great until I added variables for year, month, and day. I was trying to avoid errors so I changed a text input named "date" into 3 select boxes named "year", "month", and "day" (on the first page) and added a function to piece them all together (on the second page). I did all tis the same way I changed my code to make it receive the variables of "band" and "date" but this time I get a bunch of undefined index notices. Any more ideas?

Code from the second page:

Actually, some times it works perfectly and sometimes it doesn't work at all. I have no idea what I could be doing differently...

woodsonoversoul · December 18, 2008

I hate to bump myself, but I guess I'll do it anyway... bump

woodsonoversoul · December 18, 2008

I'm getting errors on these lines:

$band = $_POST['band'];
$year = $_POST['year'];
$month = $_POST['month'];
$day = $_POST['day'];

and

$setOne = $_POST['setOne'];

I think the error(s) lies somewhere in here:

<form  enctype="multipart/form-data" action="upload_script_ver2.php" method="post">
<?php
//create hidden values to be passed to the next page
echo "<input type =\"hidden\" name =\"band\" value =\"" . $band . "\" />";
echo "<input type =\"hidden\" name =\"year\" value =\"" . $year . "\" />";
echo "<input type =\"hidden\" name =\"month\" value =\"" . $month . "\" />";
echo "<input type =\"hidden\" name =\"day\" value =\"" . $day . "\" />";
echo "<input type =\"hidden\" name =\"setOne\" value =\"" . $setOne . "\" />";

//use a for loop to produce multiple upload boxes
for($i = 0; $i < count($set_one); $i++){
?>   
<input type ="hidden" name = "MAX_FILE_SIZE" value = "209715200" />

<fieldset><legend>Select a mp3 to upload:</legend>

<p><b>file:</b><input type="file" name ="upload[]" /></p>
</fieldset>

<?php

}
?>

<div align="center"><input type="submit" name="submit" value="Submit" /></div>
<input type="hidden" name="submitted" value="TRUE" />
</form>
</body>
</html>

Anyone see any errors? Maybe even somewhere deeper (in php.ini)?

flyhoney · December 18, 2008

You are getting errors because you are checking for $_POST data when no form has been posted, or you are checking for $_POST data that does not exist. It is often a good idea to make sure a form has been submitted before accessing $_POST data. Something like this:

if ($_POST && $_POST['submit'] == 'Submit') {
    $band = $_POST['band'];
    $year = $_POST['year'];
    $month = $_POST['month'];
    $day = $_POST['day'];
}

Alright well now I'm kinda of lost. Anyone want to take a once over look at my code?

The setup of two pages, one calling itself, for a total of three page calls is still the same.

and here's my errors: (Note:these all appear on the first load of the second page, that is, before I try to upload anything)

Notice: Undefined index: submitted in /opt/lampp/htdocs/MSNTesting/upload_script_ver2.php on line 128

Which is the line:

if ($_POST && $_POST['submit'] == 'Submit') {

Notice: Undefined variable: date in /opt/lampp/htdocs/MSNTesting/upload_script_ver2.php on line 146

Which is the line:

$unique_show_id = showIdCreator($band, $date);

and

Notice: Undefined variable: date in /opt/lampp/htdocs/MSNTesting/upload_script_ver2.php on line 218

Which is the line:

echo "The show date is: " . $date . "<br>";

Since I'm getting errors for some of the variables but not others I'm a little confused

woodsonoversoul · December 18, 2008

You are getting errors because you are checking for $_POST data when no form has been posted

I understand why I'm getting the errors, I just don't understand why the variables aren't posting.

P.S. Thanks for your help flyhoney

woodsonoversoul · December 18, 2008

Now I'm using the code:

if ($_POST && $_POST['submit'] == 'Submit') {
    $band = $_POST['band'];
    $year = $_POST['year'];
    $month = $_POST['month'];
    $day = $_POST['day'];
    $date = create_date($year, $month, $day);
    $setOne = $_POST['setOne'];
}

    $year = $_POST['year'];
    $month = $_POST['month'];
    $day = $_POST['day'];
    $date = create_date($year, $month, $day);
    $setOne = $_POST['setOne'];

and the only error I get is:

Notice: Undefined index: submit in /opt/lampp/htdocs/MSNTesting/upload_script_ver2.php on line 128

Which I guess I'm fine with, but I'd like to understand why I need both the if statement and the assignment statements when it looks to me like they do the exact same thing. Plus there's no assignment statement for $band outside of the if statement but It's still passed both times the page is called, and I don't understand that either. Any insight?
