PHP - Check If File Is Referenced To

A beginner question..

I have tried "isset" but it aint working.. I wonder what PHP function to use to check if a user actually put a file to be uploaded on the server. A validation  just in case a user just click the submit button w/out even choosing a file first.


I have this code but it aint working...

Code: [Select]
<?php
if(isset($_POST['submit']))
{

if(isset($_FILES['uploaded_file']))
{
echo "<span class=\"error_validation\">You haven't choose a logo to upload!<br></span>";
echo "<span class=\"error_validation\">Upload Logo Again? <a href=\"edit_logo.php\">Click Here</a><br></span>";
}
else
{

if($_FILES['uploaded_file']["type"] == "image/gif")
{


$target_path = "logo/";

$target_path = $target_path. basename('matzhee_logo.gif');



if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path))
{
echo "<span class=\"error_validation\">The Logo has been successfully changed! Refresh the page to see the changed!<br></span>";
echo "<span class=\"error_validation\">Upload Logo Again? <a href=\"edit_logo.php\">Click Here</a><br></span>";
}
else
{
echo "<span class=\"error_validation\">There was an error uploading the logo. Pls. try again.<br></span>";
echo "<span class=\"error_validation\">Upload Logo Again? <a href=\"edit_logo.php\">Click Here</a><br></span>";
}

}
else
{
echo "<span class=\"error_validation\">Invalid file format. We are only accepting image file. Pls. try again.<br></span>";
echo "<span class=\"error_validation\">Upload Logo Again? <a href=\"edit_logo.php\">Click Here</a><br></span>";
}
}

}
else
{
me_redirect_to("edit_logo.php");
}


?>

Anyone? thanks

Hi everyone, I'm still learning, but getting intermediate in PHP now, but it is still challenge to learn. I'm trying to have php check to see if one file inside folder in server, seem I could not get it right, but I tested it on other site, it works, but not this script, I don't understand why it won't work...maybe logical is wrong?

here my code:

	if ($_POST['video']) {
	        $path1 = "UPLOADS/Home/";
        $path2 = "UPLOADS/Breakfast/";
        $path3 = "UPLOADS/Spider/";
	        $scan1 = scandir($path1);
        $scan2 = scandir($path2);
        $scan3 = scandir($path3);
	        $count1 = count($scan1) - 3;
        $count2 = count($scan2) - 3;
        $count3 = count($scan3) - 3;
	        if($count1 > 0) {
            header('location:exist.html');
        }elseif ($count2 > 0) {
            header('location:exist.html');
        }elseif ($count3 > 0) {
            header('location:exist.html');
        }
	

But other site, it works:

	$scan = scandir($path);
$count = count($scan) - 3;
	echo $count;
	if($count > 1){
    echo "Hello yourself!<br />";
}
	

Anyone will help will be appreciate! Thank you!

how to put code for check file size before upload  in the if issertfile .the file is in format pdf or docs 

 $targetDirg= "folder/pda-semakan/gambar/";
 if(isset($_FILES['gambar'])){
     $fileNameg = $_FILES['gambar']['name'];
 $targetFilePathg = $targetDirg . $fileNameg;
 //$main_tmp1 = $_FILES['surat']['tmp_name'];
 $moveg =move_uploaded_file($_FILES["gambar"]["tmp_name"], $targetFilePathg);
 }  
         
 

 

I have a function to writes data I want to make sure it was successful.

my function:
Code: [Select]
function save_ini_file($filename,$content)
{
$File = "ini_files/". $filename . ".ini";

echo $File;
$Handle = fopen($File, 'w');
$info = $content;
fwrite($Handle, $info);
fclose($Handle);

  return true;
}
the if statement that calls the function.
Code: [Select]
if(!save_ini_file($serial,$data))
{
echo "did not write";
}else{
echo "did write";
}

the file is being created but I am getting the "did not write" echoed

I need to check (from a Debian server to a Mac CLIENT (not server) machine) to see if a file exists on the file system...not an http server.

Here's what I've tried (based on reading at http://www.php.net/manual/en/function.ssh2-exec.php)

Code: [Select]
<?php
function check_remote_files($username, $hostname, $remote_file)
{
$connection = ssh2_connect($hostname, 22, array('hostkey'=>'ssh-rsa'));

if (ssh2_auth_pubkey_file($connection, $username,
                          '/root/.ssh/id_rsa.pub',
                          '/root/.ssh/id_rsa', '')) 
{
echo "Public Key Authentication On Server #2 Successful\n";
}

$url = "if ssh $hostname stat $remote_file \> /dev/null 2\>\&1";
$stream=ssh2_exec($connection,$url);
    stream_set_blocking( $stream, true );
    $cmd=fread($stream,4096);
fclose($stream);

$stream=ssh2_exec($connection,"then");
    stream_set_blocking( $stream, true );
    $cmd=fread($stream,4096);
fclose($stream);

$stream=ssh2_exec($connection,"echo File exists");
    stream_set_blocking( $stream, true );
    $cmd=fread($stream,4096);
fclose($stream);

$stream=ssh2_exec($connection,"else");
    stream_set_blocking( $stream, true );
    $cmd=fread($stream,4096);
fclose($stream);

$stream=ssh2_exec($connection,"echo Not found");
    stream_set_blocking( $stream, true );
    $cmd=fread($stream,4096);
fclose($stream);

$stream=ssh2_exec($connection,"fi");
    stream_set_blocking( $stream, true );
    $cmd=fread($stream,4096);
fclose($stream);

}
?>

NOTHING happens after the echo of Public Key Authentication On Server #2 Successful.

I'm running this script from a bash shell.

Any ideas what might be wrong?

Thanks.

Hi all

My code give this:

<b>Warning</b>:  file_exists(): open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (/home/clients/........

I get the tmp folder and check for its existanse and whether it is writeable

$t=sys_get_temp_dir();
writelog("t=$t");
if(file_exists($t)) writelog("t1=YES"); else writelog("t1=NO");
if(is_writable($t)) writelog("t2=YES"); else writelog("t2=NO");

Both gives no which is fine, I can process that. I do it to avoid the output above, but I still get that.

How should I check for allowed paths?

This runs on several systems where I cannot access php.ini or other system stuff.

 

I want to add a note field and a checkbox to my list/grid page and save this information to a json file using uomptrucknumber as the key. The note information will be information for the whole truck not by order. The check box will let them know that the truck is ready to have paper work printed.

I have not add the note field or checkbox because I did not want to start off wrong.

how to get the name of the file including a file from the included file,

This one has me mixed up a bit.. I am trying to record site activity information from a common.php file using a user object. But since the file is included into different php files based on different situations I need a dynamic way of finding the file name that is including it. I could be over complicating things but right now this seems like the best solution other wise I'll have to rewrite the code on every page i write. Is there a function for doing this? Or if someone gets what I'm trying to do if they could point me to the direction of some more information on it.

Thanks.

I'm using an Upload Script, and I've been working on trying to style the 'Choose File Button' (input file button)

Hey everyone, I'm pretty new to this, not my full time job, but just something I thought I'd give a shot...

I have a database, in postgres, in which I make my query and I go fetch all the info I need.
What I need to do next is the tricky part for me.

For each line of results received, I have to output to a text file (.txt) but I have to respect a format that was given to me from the person requesting the info.

Example:
Character 1 must be G or N.
Character 2 to to 11 will be a result from my database search, which is a 10 digit string.
Character 12 to 14 must be spaces.

Another rule is:
start at character 78: input a value from my database search but it must not exceed 20 characters and if it is less then 20 character, fill the remaining with spaces.


If anyways has a code I can copy and work off of I would really appreciate it....thanks!

In this multi file upload form, choose three images, click submit and preview the images on the preview page. If the user wishes to delete or replace an image, click edit and the form will go back to the previous page. Select the replace radio button for example on one of the three images and select a new image from the file input prompt and click submit. The form will go to the preview page again to display the images. During this process the image names are being input into a table and the images are being moved to a directory.

The table is

  `id`  AUTO_INCREMENT,
  `image0`
  `image1`
  `image2`
  `status`

So input name='image[image0]' can be directed to table `image0` and so on.

The code for keep and delete work fine, but how do I replace an image?
I have two foreach blocks. The first one deletes the image file from the directory and deletes the image name from the table, but the second foreach dose not move the new image file into the directory.
Thanks.

<input type='radio' name='image[image0]' value='keep' checked='checked'/>
<input type='radio' name='image[image0]' value='delete' />
<input type='radio' name='image[image0]' value='replace' />
<input type="file" name="image[]" />

<input type='radio' name='image[image1]' value='keep' checked='checked'/>
<input type='radio' name='image[image1]' value='delete' />
<input type='radio' name='image[image1]' value='replace' />
<input type="file" name="image[]" />

<input type='radio' name='image[image2]' value='keep' checked='checked'/>
<input type='radio' name='image[image2]' value='delete' />
<input type='radio' name='image[image2]' value='replace' />
<input type="file" name="image[]" />

<?php
if (isset($_POST['status'])) {

$status = $_POST['status'];
$confirm_code = $status;

#--------------------------- replace --------------------------------------------

if (isset($_POST['submitted']) &&
($image = $_POST['image'])) {

foreach($image as $imageKey => $imageValue) {
if ($imageValue == 'replace') {
$query = "SELECT $imageKey FROM table WHERE status = '$status' ";
if($result = $db->query( $query )){
$row = $result->fetch_array();
}

unlink( UPLOAD_DIR.$row[0] );

$query = "UPDATE table SET $imageKey = '' WHERE status = '$status' ";
}
}

foreach($image as $imageKey => $imageValue) {

$filenm = $_FILES['image']['name']; 
$file = $_FILES['image']['tmp_name'];

Hiya,

Firstly, I'm a complete novice, apologies! But I have got my upload.php working which is nice. I will post the code below.

However, I would now like to restrict the file size and file type to only word documents.

I currently have a restriction of 200KB but it's not working - no idea why as I've looked at other similar codes and they look the same.

Also, just to complicate things - can I stop files overwriting each other when uploaded? At the moment, if 2 people upload files with the same name one will overwrite the other.

Is this too many questions in 1?

Any help is very much appreciated!

Code below:

Code: [Select]
<form enctype="multipart/form-data" action="careers.php" method="POST">
        Please choose a file: <input name="uploaded" type="file" /><br />
<input type="submit" value="Upload" />
</form>

<?php 
 $target = "upload/"; 
 $target = $target . basename( $_FILES['uploaded']['name']) ; 
 $ok=1; 
 
 //This is our size condition 
 if ($uploaded_size > 200) 
 { 
 echo "Your file is too large.<br>"; 
 $ok=0; 
 } 
 
 //This is our limit file type condition 
 if ($uploaded_type =="text/php") 
 { 
 echo "No PHP files<br>"; 
 $ok=0; 
 } 
 
 //Here we check that $ok was not set to 0 by an error 
 if ($ok==0) 
 { 
 Echo "Sorry your file was not uploaded"; 
 } 
 
 //If everything is ok we try to upload it 
 else 
 { 
 if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) 
 { 
 echo "Your file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded."; 
 } 
 else 
 { 
 echo "Sorry, there was a problem uploading your file."; 
 } 
 }

Hi everybody. 

I use flash 8 and actionscript 2.0. I am trying to create a small program that needs communication between php / HTML and flash. I have found ( after much frustration and having wasted days on this ) that no matter what - if i make a change to my program and re publish the HTMl AND SWF files after I have deleted the old HTML and swf files , even then when i run the NEW PUBLISHED html / php file, the movie that runs is the old one. I have tried all that I know, like checking paths and stuff to ensure that everything is ok. I am unable to shed the chached old swf file and so the old movie continues to run. 

Is there any one who has encountered anything like this? Please help me. This is driving me nuts. Thanks loads in anticipation of a reply from the nerds on this !

I havent included the whole title as it wouldnt let me but I was wondering if someone could help me on this?

I know this is possible as torrentflux caters for this but unsure of where to start.

I dont want to allow file or directory uploads or creation in my /etc/php.ini file (this is turned off).

Yet then torrentflux allows me to link a torrent from an external source (using legal downloads of course  ) but then it uploads it on my server and creates folders on a per user basis.

How is this possible can someone give me some pointers please?

I look forward to any replies,
Jeremy.

I have a page using forms to help build listing templates for eBay. I have a folder where I have hundreds of logos stored. I know the logo names but not their extensions. . . . I have to test each potential (jpg, jpeg, gif, png, etc.) until I guess right. Here is an example code for the web form: <form action="extension_test2.php" method="post">
<p>Logo: <input name="e" value="" type="text" size="15" maxlength="30" /><p>
<input name="Submit" type="Submit"/>
</form>   and the form's result: <?

$e =$_POST['e'];

if(!empty($e)) {
echo '<img src="http://www.gbamedica...ebayimg/logos/'.$e.'">';
};

?>   Here is a link to the example: http://www.gbamedica...ension_test.php Use "olympus.jpg" for test. I am looking for code that can determine the file type and dynamically add the extension. Can it be done?
