PHP - Client - Side Uploading Problem

I was wondering about developing simple client side graphical apps. I was thinking of using php with an ODBC connection to the data store. The data store might be a text file in CSV format or something similar. (maybe even a spreadsheet)! I was wondering what would be a very simple minimally useful web server to run on the client? The client would probably be MS Windows XP/7.   What are your thoughts?  

I want to do simple client side validation but I don't know Javascript.  Can someone point me to an easy example on how to implement or post something here?

Is it possible adding a button with PHP, which could be used for adding an optional text input field by client side user? My purpose is actually very simple: The client side users could be free creating and adding more and customized variables, which are intended to be used as strings and related or associated variables.
So, am I able to do these kind of tasks simply using PHP alone? Or, should I use some JavaScript like technologies to make those functions available in real world's practices?

Hi All - I'm trying to see if the below is possible using PHP.

is it possible for php to allow a user to check if a port is open/listening on a remote server/PC, from their local machine. I've seen scripts on the web that talk about opening cmd.exe - this won't work as not all of my users will be on windows. Also saw fsock.. but the remote server is not serving http page(s). Also saw telnet, but again, some of my users may not have that windows feature enabled.

Desired workflow:

1. user enters the server hostname/IP and a port

2. my php webapp will emulate checking if that hostname and port is open from the local user's computer.

 

thanks!

I am having trouble getting my upload file to work...

Form HTML:
Code: [Select]
<form action="" method="POST">
<input type="file" name="file" />
<input type='"submit" name="upload" value="Upload" />
</form>

PHP:
Code: [Select]
if($_POST["upload_avatar"]){
$upload_path = "images/users/";
$file = $_FILES["file"]["name"];
$extension_types = array("gif","jpg","jpeg","png");
if($file){
$filename = stripslashes($_FILES["file"]["name"]);
$extension = getExtension($filename);
$extension = strtolower($extension);
$size = filesize($_FILES["file"]["tmp_name"]);
if(in_array($extension, $extension_types)){
if($size <= $max_file_size){
$file_search = glob($upload_path . strtolower($username) . '*');
array_map("unlink", $file_search);

$file_name = $upload_path . strtolower($username) . "." . $extension;
$copied = copy($_FILES["file"]["tmp_name"], $file_name);
if (!$copied){
$r_error = "Upload has failed";
}
}
else{$r_error = "File too big";}
}
else{$r_error = "Unknown file extension";}
}
else{$r_error = "No file chosen";}
}

Every time, it gives me the "No File Chosen" error.  It doesn't seem to be actually uploading the file... I hope this isn't just some stupid thing I am looking over, can someone help me?

This is my PHP code which uploads the image from a html form.

problem: when i try to upload image from the desktop which contains image named  (test.jpg) , this test.jpg is not shown when browsing to select the image file.

any advice... 

Hi,

I have a strange problem with uploading files. My script was working fine on the test server but since moving to the live server it isn't working. Here is a printout of the FILES variable:

Code: [Select]
Array
(
    [file] => Array
        (
            [name] => filename.ppt
            [type] =>
            [tmp_name] =>
            [error] => 1
            [size] => 0
        )

)
Does anyone know what the problem might be? The error message that comes back is 'Invalid file'.

Code: [Select]
function upload_ppt_files() {

echo 'print_r($_FILES) = '.print_r($_FILES).'<br />';

global $CFG;

if (($_FILES["file"]["type"] == "application/vnd.ms-powerpoint") && ($_FILES["file"]["size"] > 100))
  {
  if ($_FILES["file"]["error"] > 0)
{
$CFG->message = "Error code:". $_FILES["file"]["error"];
manage_ppt_files();
}
  else
{

if (file_exists("../../uploads/" . $_FILES["file"]["name"]))
  {
$CFG->message = $_FILES["file"]["name"] . " already exists.";
manage_ppt_files();
  }
else
  {
  move_uploaded_file($_FILES["file"]["tmp_name"], "../../uploads/" . $_FILES["file"]["name"]);
$CFG->message = "File uploaded successfully.";
manage_ppt_files();
  }
}
  }
else
  {
$CFG->message = "Invalid File.";
manage_ppt_files();
  }

}

Hi All, I have been having issues for several days uploading a simple pdf file via Curl to one of our service providers servers.  I'm doing an is_uploaded_file check and getting a successful response, but the document is not actually being uploaded to the server. Can anyone help?? Please see code below:

Code: [Select]
$filename = $_FILES['activity_doc']['name']; // Name of the file (including file extension).
$upload_path = https://upload_url

//Curl session initialized
$session = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
curl_setopt($session, CURLOPT_URL, $upload_path);
curl_setopt($session, CURLOPT_USERPWD, 'username:password');
curl_setopt($session, CURLOPT_POST, 1);


$post = array(
        "file_box"=>"@" . $filename,
    );


curl_setopt($session, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($session);

if (is_uploaded_file($_FILES['activity_doc']['tmp_name'])) {
   echo "File ". $_FILES['activity_doc']['name'] ." uploaded successfully.\n";
} else {
   echo "Error occurred, file uploaded unsuccessful";
}

$req = new SimpleXMLElement($response);
print_r($req);
curl_close($session);

hi, i am working on an assignment in which i am getting current date and then getting date of two previous months i.e

2010-09
2010-08
2010-07

the problem is that the code is working perfectly on localhost but when i upload the file it only shows the current date and do not subtract and display dates. can some body guide me that what is the problem and how to solve it.

here is the code


$date1= date("Y-m");

$date2 = strtotime ( '-1 month' , strtotime ( $date1 ) ) ;
$date2 = date ( 'Y-m' , $date2 );

$date3 = strtotime('-1 month', strtotime( $date2 ) );
$date3 = date( 'Y-m' , $date3);
?>

<select name="">

<option><?php echo $date1;   ?></option>
<option><?php echo $date2;   ?></option>
<option><?php echo $date3;   ?></option>

</select>

I developped a cms system to upload images with php to a mysql database and a upload folder on the server.
Firefox version 5.0.1 for MAC and earlier have no problems with uploading through the script. But after that version it is impossible to upload images bigger then 250kb. The page where the customer chooses his image for upload stalls and the form is not sent to the actual upload script, which should validate and process the image. This problem only occurs in Firefox, all other browsers work just fine!
I tried to run the same script with Firefox on a PC and everything works fine. So it is a Mac related problem.

You can try for yourself to see what happens in the following basic script (if you don't get a succes message it means that you are still hanging on the image_upload page and nothing has happened) :
