[SOLVED] Warning: fread(): supplied argument is not a valid stream

[pcbytes]

I am getting the following error in my little applet to upload images to my database.

 

Warning: fread(): supplied argument is not a valid stream resource in C:\apache\htdocs\upload.php on line 4

 

The script connects to the database no problem. It even creates a new entry. But the entry is blank, and my browser spits out the above mentioned error. Whats wrong in my code?

 

submit.php

 

<form method="post" action="upload.php" enctype="multipart/form-data">
Description:<br>
<input type="text" name="form_description" size="40">
<input type="hidden" name="MAX_FILE_SIZE" value="10000000">
<br>File to upload:<br>
<input type="file" name="form_data" size="40">
<p><input type="submit" name="submit" value="submit">
</form>

 

upload.php

 

<?php
mysql_connect("localhost","jason","password");
mysql_select_db("test");
$data = addslashes(fread(fopen($form_data, "r"), filesize($form_data)));
$result=MYSQL_QUERY("INSERT INTO uploads (description, data,filename,filesize,filetype) ". "VALUES ('$form_description','$data','$form_data_name','$form_data_size','$form_data_type')");
$id= mysql_insert_id();
print "<p>File ID: <b>$id</b><br>";
print "<p>File Name: <b>$form_data_name</b><br>";
print "<p>File Size: <b>$form_data_size</b><br>";
print "<p>File Type: <b>$form_data_type</b><p>";
print "To upload another file <a href=http://192.168.1.66/submit.php> Click Here</a>";
?>

Replace

 

$data = addslashes(fread(fopen($form_data, "r"), filesize($form_data)));

 

with

 

$filehandle = fopen($form_data, "r");
if ($filehandle === false) die("Couldn't open $form_data");
$filesize = filesize($form_data);
if ($filesize === false) die("Couldn't get filesize for $form_data");
$data = fread($filehandle, $filesize);
if ($data === false) die("Couldn't read from filehandle");
$data = addslashes($data);

 

Edit: Actually, you could just use file_get_contents().  Again, check for errors!  You might want to check if $form_data is empty first, using if (empty($form_data)) { ... }
