Im having trouble on updating the file inside mysql database using the php. Should I use <form> or im wrong on how I called the variable from previous page?
FORM 1 - that accepts the file pointer to upload. -
# Get the ID
-
$id = $_GET['id'];
-
.....
-
echo "<p>Replace CMR Document: <input type=\"file\" name=\"uploaded_file\" size=\"43\">";
-
echo "<a href='replaceCMR.php?id=$id}'>Replace";
FORM2 - the php script that will update mysql. - <?php
-
# Check if a file has been uploaded
-
if(isset($_FILES['uploaded_file']))
-
{
-
# Make sure the file was sent without errors
-
if($_FILES['uploaded_file']['error'] == 0)
-
{
-
# Connect to the database
-
.....
-
-
# Gather all required data
-
$name = mysql_real_escape_string($_FILES['uploaded_file']['name'], $dbLink);
-
$mime = mysql_real_escape_string($_FILES['uploaded_file']['type'], $dbLink);
-
$size = $_FILES['uploaded_file']['size'];
-
$data = mysql_real_escape_string(file_get_contents($_FILES ['uploaded_file']['tmp_name']), $dbLink);
-
-
-
# INSERT SQL query
-
$query = "
-
UPDATE fileStorage
-
SET FileName= '{$name}',
-
FileMime ='{$mime}',
-
FileSize = {$size},
-
FileData = '{$data}'
-
WHERE FileID = {$id}";
-
-
-
# Execute the INSERT QUERY
-
$result = mysql_query($query, $dbLink);
-
-
# Check if it was successfull
-
if($result)
-
{
-
echo "<b>Success! ";
-
}
-
else
-
{
-
echo "Error! Failed to updatethe file";
-
echo "<pre>". mysql_error($dbLink) ."</pre>";
-
}
-
}
-
else
-
{
-
echo "Error!
-
An error accured while the file was being uploaded.
-
Error code: ". $_FILES['uploaded_file']['error'];
-
}
-
-
}
-
else
-
{
-
echo "Error! A file was not sent!";
-
}
-
-
-
?>

to make a little bit simple.
form - <html>
-
<body>
-
-
<form action="replaceCMR1.php" method="post"
-
enctype="multipart/form-data">
-
<label for="uploaded_file">Filename:</label>
-
<input type="file" name="file" id="file" />
-
<br />
-
<input type="submit" name="submit" value="Submit" />
-
</form>
-
-
</body>
-
</html>
uploader - <?php
-
# Check if a file has been uploaded
-
if(isset($_FILES['uploaded_file']))
-
{
-
# Make sure the file was sent without errors
-
if($_FILES['uploaded_file']['error'] == 0)
-
{
-
# Connect to the database

.....
-

# Gather all required data

$name = mysql_real_escape_string($_FILES['uploaded_file']['name'], $dbLink);

$mime = mysql_real_escape_string($_FILES['uploaded_file']['type'], $dbLink);
-
$size = $_FILES['uploaded_file']['size'];
-
$data = mysql_real_escape_string(file_get_contents($_FILES ['uploaded_file']['tmp_name']), $dbLink);

-

-
FileSize = {$size},
-
FileData = '{$data}'
-
WHERE FileID = {$id}";
-
-
-
# Execute the INSERT QUERY
-
$result = mysql_query($query, $dbLink);
-
-
# Check if it was successfull
-
if($result)
-
{
-
echo "<b>Success! Your file was successfully added!<br>";
-
echo "Email alert was sent to reviewer's group</b>";
-
-
}
-
else
-
{
-
echo "Error! Failed to insert the file";
-
echo "<pre>". mysql_error($dbLink) ."</pre>";
-
}
-
}
-
else
-
{
-
echo "Error!
-
An error accured while the file was being uploaded.
-
Error code: ". $_FILES['uploaded_file']['error'];
-
}
-
-
}
-
else
-
{
-
echo "Error! A file was not sent!";
-
}
-
-
?>

-
$size = $_FILES['uploaded_file']['size'];
-
$data = mysql_real_escape_string(file_get_contents($_FILES ['uploaded_file']['tmp_name']), $dbLink);

I have a table with ~2.2 million rows. Sometimes when I do an update
to one single row it will instead update ALL of the rows using the
same update. This happens every one in about 500,000 updates to a
single row.
I am running mysql 4.0.14 in WinXP. I am using PHP to do the update.
I am thinking something in the update itself is causing mysql to do
this. I don't have the exact SQL statement that causes the error
