PHP txt/doc Upload, and make url to it?

[Breana]

Ok, i want to make a simple upload where it accepts only txt/doc files rejects other files and saves (tru) files to a folder uploads
.
After display a message (upload complete) Link:
And have it post the url to the txt/doc file they just uploaded.

so it will pop up like uploads/myfile.txt, so they can link it in the walkthrough form.
So far i have 2 files, addwalkthrough.php and savewalkthrough.php but i cant get it to echo the file link...

[PHP]<form action="savewalkthrough.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>

<?php
if (($_FILES["file"]["type"] == ".txt")
|| ($_FILES["file"]["type"] == ".doc")
&& ($_FILES["file"]["size"] < 20000))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

if (file_exists("upload/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
}
}
}
else
{
echo "Invalid file";
}
?>[/PHP]

What did i do wrong it keeps saying invalid file...
.txt

Hi there Breana,

I think your error is coming in the way you are using the $_FILES['type'] variable from the $_FILES superglobal. Type is actually the type of file you are uploading, not the file extention. If you wanted to check based on the file extention, you could do something like this:

[PHP]<?
$fileType=explode('.',$_FILES['type']);
$type=$fileType[1];

//will give you the actual file extention
echo $type;
?>[/PHP]

If you want to see the different elements you have available to you, you could run the code below:

[PHP]<?php
foreach($_FILES as $k => $v){
foreach ($_FILES[$k] as $kk => $vv){
echo "$kk => $vv<br />";
}
}
?>[/PHP]

So, your code is working properly. Congrats! It may not be doing what you want, but you should be able to tweak the "type" to get the desired result. If you have any other problems post back here.

In looking for more information, I noticed that w3schools has almost the exact same PHP code that your using. Note the way they are using the "type", it's not a file extention, rather something like "image/gif" or text/plain.

Lol, i am using a php book my dad baught me :)
But it dont give fils ext. or how to set them that i see anyway lol.
I dont get this:

[PHP]$fileType=explode('.',$_FILES['type']);
$type=$fileType[1];
//will give you the actual file extention
echo $type;[/PHP]

I need it to check if its a .txt, .doc and upload it.
What does that do?
I just want to know how to get it to detext the wright files in the code above lol.

Is it .text?

Hi.

The $_FILES[$x]['type'] variable stores the MIME type of the uploaded file.
For text files this would return 'text/plain' and for .doc types it should return 'application/msword'.

Check out this list of MIME types at w3schools.com

I know this stuff can be confusing. In your original code your saying

if $_FILES["file"]["type"] == ".txt" then do something. This is incorrect as your checking the file extention, and not the file type. The explode code I mentioned before would allow you to check the file extention. To be more accurate, your upload code should check like this:

[PHP]<?
if($_FILES["file"]["type"] == "application/msword" || $_FILES["file"]["type"] =="text/plain"){
//do something
}
?>[/PHP]

You just need to change how your using the files array, and check for the proper type, instead of checking for file extention.

Post back if you need more help. This can be a very confusing topic, and we are here to help!
