Help with File Uploads

Ult1matek1ll · February 16, 2012

My goal is to allow the user to select whether or not they want to replace the current img files. If so delete all current ones in select dir and upload into it. If not then began uploading at a specific point such that.

1.jpg

2.jpg

3.jpg

...

and so on

(replace yes deletes all and no deletes none)

The directories are assigned previously and are accessed via sql database

These are the two current sets i have

<?php $page_title = "Central Valley LLC | Photo Addition" ?>

<?php include("header.php"); ?>

<?php include("nav.html"); ?>

<label for="which">Choose A Product:</label>

<?php $con = mysql_connect("localhost","phoenixi_cv","centraladmin");

if (!$con)

{

die('Could not connect: ' . mysql_error());

}

mysql_select_db("phoenixi_cvproducts", $con);

$result = mysql_query("SELECT * FROM Products");

echo "<select>";

while($row = mysql_fetch_array($result))

{

echo "<option ";

echo "value=\"" . $row['num'] . "\">";

echo $row['Name'] . "</option>";

}

echo "</select>";

mysql_close($con);

?>

<br />

<h3 id="center">Do You Wish To Replace Current Images?</h3>

<br />

<input type="radio" name="replace" value="n" />NO

<br />

<br />

</form>

</div>

<?php include("footer.html") ?>

and this is the upload script so far

}

foreach ($_FILES["uploads"]["error"] as $key => $error)

{

if ($error == UPLOAD_ERR_OK)

{

echo"$error_codes[$error]"; // let you know if there was an error on any uploads

move_uploaded_file( //php function to move the file

$_FILES["uploads"]["tmp_name"][$key], //from the temporary directory

$uploaddir. $_FILES["uploads"]["name"][$key] //to the directory you chose

) or die("Problems with upload");

}

foreach($_FILES["uploads"]["name"] as $bla=> $boo)

{

$file=$uploaddir.$boo;

$movepoint = $uploaddir . $count . '.jpg';

rename($file, $movepoint);

$count++;

}

?>

' target='_blank'><?php

$count = 1;

if($_POST[replace]=='y')

{

$mydir = 'assets/images/' . $_POST['which'] . '/';

$d = dir($mydir);

while($entry = $d->read())

{

if($entry!="." && $entry!="..")

{

unlink($entry);

}

else

{

$loop = true;

while($loop == true)

{

$filename = 'assets/images/' . $_POST['which'] . '/' . $count . '.jpg';

if(file_exists($filename))

{

$count++;

}

else

{

$loop = false;

}

if(!is_dir("uploads/".$id))

{ //this checks to make sure the directory does not already exist

mkdir("uploads/".$id, 0777, true); //if the directory doesn't exist then make it

chmod("uploads/".$id, 0777); //chmod to 777 lets us write to the directory

}

$uploaddir = 'assets/images/' . $_POST['which'] . '/';

foreach($_FILES["uploads"]["name"] as $bla=> $boo)

{ //we have to do a loop to get all the filenames

$file=$uploaddir.$boo; //we will check the filename in the upload directory, see if it exists

if (file_exists($file))

{ //if it exists then ......

die("Filename already exists, please rename this file"); //if filename exists in the directory then we die!!!

}

foreach ($_FILES["uploads"]["error"] as $key => $error)

{

if ($error == UPLOAD_ERR_OK)

{

echo"$error_codes[$error]"; // let you know if there was an error on any uploads

move_uploaded_file( //php function to move the file

$_FILES["uploads"]["tmp_name"][$key], //from the temporary directory

$uploaddir. $_FILES["uploads"]["name"][$key] //to the directory you chose

) or die("Problems with upload");

}

foreach($_FILES["uploads"]["name"] as $bla=> $boo)

{

$file=$uploaddir.$boo;

$movepoint = $uploaddir . $count . '.jpg';

rename($file, $movepoint);

$count++;

}

?>

Thanks in advance for any help that you can give me.Also if you can suggest any easier ways i would certainly be obliged.

Please post code in [ code][ /code] tags.

Also I don't see a question anywhere. What is the problem?

It currently fails to upload any files and i was curious if i was approaching this at all in the right manner

Can you post the output of :

echo '<pre>' . print_r($_FILES, true) . '</pre>';

Ult1matek1ll · February 16, 2012

when yes radial button pressed for empty dir nothing echoed...

when no radial button pressed for empty dir nothing yet again...

when yes radial button pressed for populated dir nothing echoed...

when no radial button pressed for populated dir nothing yet again...

sadly nothing is being echoed what-so-ever

if you would like me to add an echo into the code and test it i will thank you for your help

Ult1matek1ll · February 16, 2012

Your echo "<select>"; should have a name, eg

echo "<select name=\"product_id\">";

Ult1matek1ll · February 16, 2012

Thank you drummin

That worked so far will proceed with some more test and reply again

Ult1matek1ll · February 16, 2012

ok works for the most part the only issue i am having is if there are more images than i am uploading to replace it holds on to them still such that

1.jpg

2.jpg

3.jpg

4.jpg

5.jpg

and i upload only 3 imgs per say: one.jpg,two.jpg,three.jpg(names used as examples the php upload script renames them as listed in the first part)

my output would be

one.jpg

two.jpg

three.jpg

4.jpg

5.jpg

Drummin · February 16, 2012

Not sure. Would adding

unset($_FILES);

at the end of processing, clear things out for the next upload?

Not sure if that's the problem.

Ult1matek1ll · February 16, 2012

found the problem it was at the beginning with the unlink item.

former code

while($entry = $d->read())
	{
		if($entry!="." && $entry!="..")
		{
			unlink($entry);
		}
	}

new code

while($entry = $d->read())
	{
		if($entry!="." && $entry!="..")
		{
			unlink('assets/images/' . $_POST['which'] . '/' . $entry);
		}
	}

Thank you so much for all of your help guys
