I am new to PHP and am trying to create a page which will change/update/refresh depending on which form buttons are selected. This part works. The purpose of the site is to allow multiple file uploads of two types of data: PHOTO and MUSIC, along with uploads of textarea text - with each type being stored in a different location. The problem I've run into is in dedicating paths for each data type (for use with the move_uploaded_file command). I can set the paths in variables, but it seems the if(isset($_FILES['whatever'])) block of code cannot see those variables. I receive no errors (as you can see, I'm testing via localhost). How should I redesign my code to accomplish the objective? I'm assuming that the problem is in the way I'm approaching the project in general.
ini_set('display_errors',1);
$MasterFolder= __DIR__;
$BodyText = "";
$BodyHeader='<form action="" method="post">
<div id="NavContainer" style="margin: 4% auto;">
<input type="submit" name="Button" value="Photos">
<input type="submit" name="Button" value="Writings">
<input type="submit" name="Button" value="Music">
</div>
</form>';
switch (htmlspecialchars($_POST['Button'])) {
case 'Photos':
$ParentFolder = $MasterFolder . '/Photo';
$DestinationFolder = $ParentFolder . '/PhotoStore';
$BodyText='<!-- Whatever -->';
break;
case 'Writings':
$ParentFolder = $MasterFolder . '/Write';
$DestinationFolder = $ParentFolder . '/WriteStore';
$BodyText='<!-- Whatever -->';
break;
case 'Music':
$ParentFolder = $MasterFolder . '/Music';
$DestinationFolder = $ParentFolder . '/musicStore';
$BodyText='<div class="EntryForm">
<div class="TextLabel">Music</div>
<form action="" style="margin: 0 auto 4% auto;" method="post" enctype="multipart/form-data">
<input type="file" name="myfile[]" multiple="multiple" />
</div>
<div class="EntryForm">
<div class="TextLabel">Description:</div>
<textarea name="MusicText"></textarea>
</div>
<div class="EntryForm">
<input type="submit" value="Publish Entry" />
</p>
</form>
</div> <!-- End ENTRYFORM div -->';
#echo $ParentFolder; ################## These two lines print the expected ##############
#echo "\n" . $DestinationFolder; #################### values #############################
break;
}
if (isset($_FILES['myfile'])) {
#echo $ParentFolder; ################## These two lines are equal to "" ##############
#echo "\n" . $DestinationFolder; ###### and I expected them to contain the values assigned in the switch/case statement above ########
foreach($_FILES['myfile']['tmp_name'] as $key => $tmp_name) {
$DFile = $DestinationFolder . htmlspecialchars($_FILES['myfile']['name'][$key]);
chmod($ParentFolder, 0777);
chmod($DestinationFolder, 0777);
move_uploaded_file($tmp_name, $DFile);
chmod($DFile, 0644);
}
chmod($DestinationFolder, 0650);
chmod($ParentFolder, 0650);
}
?>
<!DOCTYPE html>
<html lang="en">
<head><title>Publish</title>
</head>
<body>
<form action="" method="post">
<input type="submit" name="Button" value="Photos">
<input type="submit" name="Button" value="Writings">
<input type="submit" name="Button" value="Music">
</form>
<div class="EntryForm">
<?php echo $BodyText; ?>
</body>
</html>```
When you submit the second form (the one with the file) you don't re-send the 'Button' value. To circumvent this you could add a hidden input to your file-form above the 'Publish Entry'-submit-input like this:
<input type="hidden" name="Button" value="Music" />
