Passing Form Variables: Notice: Undefined index

FrankyG813

SOS!!!

I'm having trouble with passing form variables. Here's my code;

<html>
<head>
<title> A simple form for uploading a file</title>
</head>
<body>
<h2>A simple form for uploading a file</h2>
<form action="upload.php" method="post" enctype="multipart/form-data">
Enter Filename: <Input type="file" name="userfile"><br>
<input type="submit"><br>
</form>
</body>
</html>

The receiving file upload.php reads;

<html>
<head>
<title>Uploading a file sample</title>
</head>
<body>
<?php
$userfile=$_POST['userfile'];
?>
</body>
</html>

I've checked in phpinfo and register globals is ON. I'm running PHP V4.3.4 on Redhat Linux with Apache. This thing is driving me nuts. Please help.

Thanks

Frank

i don't think you use $POST. you need to use $FILES['userfile'] but that's an array too.

I think it will have ['name'] which is the name of the file that you're uploading, ['tmp_name'] which is what your server calls the file when it's uploaded, ['size'] which is the size of the file, and probably others too.

So if you want it to output the name of the file, you'd put

echo $_FILES['userfile']['name'];

to see what's in there though, you might want to use this:

while( list ( $field, $value ) = each( $_FILES['userfile']) )
{
	echo "\$_FILES['userfile']['$field'] = $value<br>";
}

Thanks John,

I tried using files as you instructed and it still gave me the undefined index error. Then I tried to code in the second option using the each array and I got the following message:

Warning: Variable passed to each() is not an array or object in /usr/local/apache2/htdocs/eporg_job_web/upload.php on line 7

sounds to me like the server isnt getting the file. you sure your web server has write access? if not then it wont let your php script copy the file to a temp file, which might be your problem.

Eureka!!!

I looked at the settings in phpinfo and I noticed that the uploads setting was turned off, also nothing assigned a value for the uploads directory. I 'ASSummed' that since no copy was taking place in the recieving form, that nothing was being uploaded....duh?!?!

Thanks John...I really do appreciate your help.

This time it's not with a file, just with text. I have a form that had been running perfectly for a long time on v4.3.3.

Now I put it on a server that is running v4.3.6 and I get the error ...
Notice: Undefined variable: submit in D:_web\SOM\molpath\db_faculty_add.php on line 5

So I check up on that and find out that I need to use <?
$submit = $_POST['submit'];
?>

(I think)

So I put it in. But then I get the error ...

Undefined index: submit in D:_web\SOM\molpath\db_faculty_add.php on line 3

And that's where it seems no one on the web has any clue what is going on. Any ideas how to get this to work?

Below is the first bit of code in the phpSelf form.

<?php

$submit = $_POST['submit'];

if ($submit) {

include ("db_connect.php");

//$description = mysql_escape_string($description);

mysql_query ("INSERT INTO faculty (name_last,name_first,disease_interest,affiliation,header_summary,url,title,email,phone,fax,biography,research_summary,reference_key,image_source, research_image_source)
VALUES ('$name_last','$name_first','$disease_interest','$affiliation','$header_summary','$url','$title','$email','$phone','$fax','$biography','$research_summary','$reference_key','$image_source','$research_image_source')");

echo "Entry Submitted.";

mysql_close ($db);

} else {

	//echo "Please Enter Information.\n";

	}

$submit = $_POST['submit'];

if ($submit) {

Try just

if(isset($_POST['submit'])) {

[man]isset[/man] checks to see if the variable is set or not - if it isn't and you try to use it, you'll get those notices about uninitialised variables. It's good practice to only use variables that actually exist 🙂

In this case, you don't really care about the submit button's value - just that the form is there. You'll want to get your other form variables with $_POST as well.

isset statement gives me the error -->Parse error: parse error, unexpected '{' in D:_web\SOM\molpath\db_faculty_add.php on line 7
