PHP - Copy File Loop

Copy File Loop	View Content

Hi all

I am trying to write a piece of code that copies files from a multiple selected form. Here's the form:

Code: [Select]
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="image[]" multiple="multiple" />
<input name="submit" type="submit" value="submit">
</form>

Here's my PHP code:

Code: [Select]
if(isset($_POST['submit'])) {
$count=0;
foreach($_FILES['image'] as $filename){
copy($_FILES['image']['tmp_name'], WEB_UPLOAD."/images/galleries/".$filename) or die("Error uploading image ");
$count++;
}
}

I get the message, Array to string conversion and no such directory found. Am I right in thinking I am sending the files as arrays?

Many thanks for your help.

Problem With Copy() And File Permissions

Similar Tutorials

View Content

Hi

Have searched this and other forums for an answer to this and found lots of similar questions but nothing dealing with exactly what I'm after.

I want to copy a file located in parent/dir1/file.pdf (for example) to another directory parent/dir2/id/file.pdf. This is straightforward enough using copy(). But... I don't want users to be able to access the original file directly (eg by just putting /parent/dir1/file.pdf into their browser. The only way I seem to be able to do this is by removing the 'read' permission, but then the copy() command gives an error.

If this is possible, I assume the solution is somehow linked to the various file and directory permissions but I can't figure out the correct settings.

Can someone help out?

Thanks in advance

Find A Directory In Expanded File And Copy Its Contents

Similar Tutorials

View Content

Seems this should be easy, but I'm not finding the solution. Functions like scandir, readdir, and glob that I've been looking at all seem to need me to actually know more about my directory path than I can ahead of time.

Here's what I want to do:
1. expand a .tar file (consists of directory, subdirectories, files, and is variable) that I've uploaded to the server
2. look through that expanded directory for a subdirectory named ".pn" -- (note that all my .tar files will have this folder deep in several subdirectories that will be variable in number and have different names depending on the original .tar file)
3. copy the entire contents of the .pn folder to another folder already on my server

The hosting company, no doubt, has likely blocked some of the functions I'll need as well, but if someone can point me in the right direction to start, it would be greatly appreciated.

Thanks!

Hello I have a problem.

I have been trying to copy my music folders structure but not copying the mp3s; instead using the file names as a file name for a .txt file and inserting the URL to the file in the .txt file.

Eg.

E:\My Music
folder 1
folder 1.1
file.mp3
folder 2
folder 3

to

G:\My Music
folder 1
folder 1.1

Ok I am designing a php upload that will take a image file from a form and change the name of the file to the productnumber also recieved from the form. I had it working the otherday now it says Warning: copy() [function.copy]: open_basedir restriction in effect File() is not within the allowed path(s): (/home:/tmp:/usr) addpro.php on line 51.

my files are attached.... note that $pnum is the product number gotten from my form and image is the image being uploaded gotten from the form also. The thing is it worked the other day but now it don't is it a change to the server ( I dont run the server) or did I mess up my code since then? I really need a code that will do this two time over once for a small image being put into a folder called small and once for a folder called large both images being uploaded and being changed to $pnum.ext so they will both be displayed when being called out by the product number. but I can work on that after I get this one working.

line 51 is $copied = copy($_FILES['image']['tmp_name'], $newname);

Php Image Upload Help: Copy() [function.copy]: Filename Cannot Be Empty In

Hi guys,

I am wirting a script to upload an image file, but I get the error:

copy() [function.copy]: Filename cannot be empty in

Obviouly it has something to do with the copy() function - (copy($HTTP_POST_FILES['product_img']['tmp_name'], $path))

I think it is not copying from my temp folder or something.

Can anyone help me out?

Code is:

Code: [Select]
//IMAGE FILE
$file_name = $_FILES['product_img']['name'];

echo '<p>File Name:' . $file_name . '</p>';
//IMAGE UPLOAD
// random 4 digit to add to file name
$random_digit=rand(0000,9999);

//combine random digit to file name to create new file name
//use dot (.) to combile these two variables
$new_image_name = $random_digit.$file_name;

echo $new_image_name;

//SET DESINATION FOLDER
$path= "uploads/".$new_image_name;
echo '<p>Path:' . $path . '</p>';
if($product_img !=none)
{
if(copy($HTTP_POST_FILES['product_img']['tmp_name'], $path))
{
echo "Successful<BR/>";
echo "File Name :".$new_file_name."<BR/>";
echo "File Size :".$HTTP_POST_FILES['product_img']['size']."<BR/>";
echo "File Type :".$HTTP_POST_FILES['product_img']['type']."<BR/>";

Clone Creates A Shallow Copy Or Deep Copy?

Similar Tutorials

View Content

I came across the PHP clone method. Does this clone first level fields and methods or does it also do deep copying e.g. copying references to those fields. For example, a field may be an array. Does it make a copy of the actual array or does it refer to the same array position in memory, so if the original changes, then the copy's changes as well?

Got a little stuck here.

I'm trying to format an existing .txt file, format it and then write it to .sql file.

Here's my code:

Code: [Select]
$handle = @fopen("nations.txt", "r");
if ($handle) {
while (($buffer = fgets($handle, 1024)) !== false) {

$column = explode("|",$buffer); // format file
$myFile = "nation_dump_".date("Y-m-d").".sql"; // create file
$fh = fopen($myFile, 'w') or die("can't open file");

foreach($column as $col)
{
fwrite($fh, $col[0]); //write the first broken segment from explode() to file
}
fclose($fh);
}
if (!feof($handle)) {
echo "Error: unexpected fgets() fail\n";
}
fclose($handle);
}

The error is on this line, within the foreach loop.
fwrite($fh, $col[0]);

When I removed the index it only wrote the last line to the file, but I want it to loop through all the lines..

What am I doing wrong here?

Need To Loop Through Xml File For Each Record

Similar Tutorials

View Content

I have a php script defined that parsed the xml file and runs through the 1st record - encased within the EOF tags.
However, I need to capture ALL records - each defined between "EOF" tags - of the select xml file that will be pass to the script.

Currently, the php script I have finds the 1st set of info from the xml file but doesn't loop through the remaining records which all encased between the "EOF" tags. I know I need a while loop but not sure on the syntax to get it through the remaining files. Any comments appreciated to help edit code to form the required loop:

$xml = simplexml_load_file($new_location);
        foreach($xml->EOF as $eof) {
             $autoNoT  = $eof->AutoNo;
             $vegregnoT = $eof->TruckNo;
             $clientIDT  = $eof->ClientID;
}

Here's the example xml file which contains multiple records that I need to extract each set of date between the <EOF></EOF> tags.
Note: the above php code extract just the 1st record then stops (I know I'm missing the loop but need help defining it...)

Code: [Select]
- <DocumentElement>
- <EOF>
<AutoNo>109531</AutoNo>
<TruckNo>XLX885GP</TruckNo>
<ClientID>3</ClientID>
</EOF>
- <EOF>
<AutoNo>109532</AutoNo>
<TruckNo>ZFN726GP</TruckNo>
<ClientID>3</ClientID>
</EOF>
- <EOF>
<AutoNo>109533</AutoNo>
<TruckNo>ZFP113GP</TruckNo>
<ClientID>3</ClientID>
</EOF>
- <EOF>
<AutoNo>109534</AutoNo>
<TruckNo>WSG299GP</TruckNo>
<ClientID>3</ClientID>
</EOF>
- <EOF>
<AutoNo>109872</AutoNo>

Loop Through Each Line Of A Text File, Add Code, And Throttle

Similar Tutorials

View Content

Here's what I'm trying to do, and I am having trouble getting started with this. It's a very simple process, but I didn't want to spend the next 6 hours in frustration, so some help getting started would be great.

Here's the purpose of the script:
1. Allow user to add a text file to a form.
2. Take the text file, add HTML code to the beginning and end of each paragraph (a single line of text, usually paragraphs would be separated by a line return)
3. Send the user an email with the HTML file attached and thank them or whatever.
4. Allow the system to throttle itself (one-at-a-time) so that many people using the site won't bog it down. These files will probably be anywhere from 100 KB to 1,000 KB in size, usually hitting in the 300-500KB range.

Here's what I can do very easily:
1. Allow user to add a text file - very simple and straightforward.
2. Take the text file, add HTML... - this is what I need a little help figuring out. Each paragraph needs to have <p> at the beginning and </p> at the end, and the script will also search for keywords on certain lines (section headers) and add a <align="center"> tag to that, and so forth. I can handle the formatting rules, but making sure the loop runs correctly could be a problem.
3. Send the user an email... - very easy, I can do that myself.
4. Allow the system to throttle itself... - this could be tricky. I was thinking a database with a TINYINT field, 0 for not processed yet, 1 for processing, 2 for processed. Cron job checks the next one on the list to see if it needs to send it to the processor, if the file is already being processed, or can be sent to a different database (completed entries) and removed from the current queue. The cron job would also be responsible for triggering the "Your file is converted!" email and the attachment.

Any/all help would be greatly appreciated on this. I am going to work on the parts that I can do myself, and I'll be checking back for the discussion - in between Mountain Dew runs.

Hello,

Originally the data comes from ~2-3 database tables, of course. But to ilustrate the point, this is how the main array looks like. This array usually contains anywhere between 10-50 rows, each row containing at least 10 dates, with 10 key/values each. And after setting up all the data, it needs to be processed. Currently this is how a friend of mine did it..

$placeDataHere = array();
foreach($firstArray as $key => $dates) {
foreach($dates as $date => $values) {
foreach($values as $key => $value) {
$placeDataHere['DV_' . $date]['SM_' . $key] = 'KS_' . $value;
//Followed by another ~50-70 lines of processing the 3 loop's data..
...
...
....
....
....
....
....
....
}
}
}

Obviously this isn't good practise, but we can't seem to figure out a better way of doing it, since both the data and the loops are horribly nested. This loop and setup of $firstArray is run anywhere between 10-20 times/request, due to amount of users we wish to process. So, the result is that this code can take up to over 2-3 minutes to complete, which isn't really optimal performance. In short my question is, are there any better methods of handling this with the data setup we currently have?

Below is my output on the browser:

Student: Kevin Smith (u0867587)
Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade
Year: 3

Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B

Session: AAB Session Mark: 72 Session Weight Contribution 20%

Session: AAE Session Mark: 67 Session Weight Contribution 40%

Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B

Session: AAD Session Mark: 61 Session Weight Contribution 50%

Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this.

Below is the code:

Code: [Select]
$sessionMark = 0;
$sessionWeight = 0;
$courseMark = 0;

$output = "";

$studentId = false;
$courseId = false;
$moduleId = false;

while ($row = mysql_fetch_array($result))
{

$sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']);
$sessionWeight += ($row['SessionWeight']);
$courseMark = ($sessionMark / $sessionWeight * 100);

if($studentId != $row['StudentUsername'])
{

//Student has changed
$studentId = $row['StudentUsername'];

$output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n";

}

if($courseId != $row['CourseId'])
{

//Course has changed
$courseId = $row['CourseId'];

$output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong> <br><strong>Year:</strong> {$row['Year']}</p>\n";

}

if($moduleId != $row['ModuleId'])
{

//Module has changed
if(isset($sessionsAry)) //Don't run function for first record
{

//Get output for last module and sessions
$output .= outputModule($moduleId, $moduleName, $sessionsAry);
}

//Reset sessions data array and Set values for new module

$sessionsAry = array();
$moduleId = $row['ModuleId'];
$moduleName = $row['ModuleName'];
}

//Add session data to array for current module

$sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']);

} //Get output for last module

$output .= outputModule($moduleId, $moduleName, $sessionsAry);

//Display the output
echo $output;
I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72?
