More Errors!

Recommended Posts

Does anyone know what would cause this error:

[i]Notice: Undefined index: file in C:\Inetpub\wwwroot\Upload\uploader3.php on line 2
No file specified[/i]

with these files for uploading images:


<html><head><title>File Uploader</title></head>
<body><h3>File Upload</h3>
Select a file to upload:<br>
<form action="uploader.php" method="post" enctype="multipart/form-data">
<input type="file" name="file" size="45">
<input type="submit" value="Upload File">


if( $_FILES['file']['name'] != "" )
copy ( $_FILES['file']['tmp_name'],
"C:/Inetpub/wwwroot/Upload/" . $_FILES['file']['name'] )
or die( "Could not copy file" );
else{ die( "No file specified" ); }

<head><title>Upload Complete</title></head>
<h3>File Upload Succeeded...</h3>

<li>Sent: <?php echo $_FILES['file']['name']; ?>
<li>Size: <?php echo $_FILES['file']['size']; ?> bytes
<li>Type: <?php echo $_FILES['file']['type']; ?>

<a href="<?php echo "C:/Inetpub/wwwroot/Upload/".$_FILES['file']['name']; ?>"><img src="<?php echo "C:/Inetpub/wwwroot/Upload/".$_FILES['file']['name']; ?>" height="200"></a>

Change [code]if( $_FILES['file']['name'] != "" )[/code] to [code]if(isset($_FILES['file']['name']) && !empty($_FILES['file']['name']) )[/code]
Put simply $_FILES['file'] array isn't set and so you recieve the notification message, the above code should stop this message form appearing as you are doing proper validation on your uploaded files, which is checing that $_FILES['file'] array is set and secoundly it isnt empty.
