Problems Uploading Files Via Php

[BuildMyWeb]

im using the following in a local php.ini file settings;

 

max_execution_time = 900 ; Maximum execution time of each script, in seconds
session.gc_maxlifetime = 900
max_input_time = 900 ; Maximum amount of time each script may spend parsing request data
memory_limit = 150M	 ; Maximum amount of memory a script may consume (16MB)
post_max_size = 150M
upload_max_filesize = 150M ; Maximum allowed size for uploaded files.

 

i have a file of 121MB that will not upload. am i missing something in the php.ini? is there more i can be doing?

 

the following i copied out of my phpinfo.php file to verify settings:

max_execution_time 900 900

session.gc_maxlifetime 900 900

max_input_time 900 900

post_max_size 150M 150M

upload_max_filesize 150M 150M

memory_limit 150M 150M

What is the error code from the upload? It's in $_FILES["whatever"]["error"].

[BuildMyWeb]

sorry i took this long to reply. cant get an error. this is what imm troubleshooting with and the response is without a value;

 

"error: "

 

if( $_FILES['upload']['error'] > 0 )
   {
       $error_msg = $_FILES['upload']['error'];
       echo"error: " . $error_msg;

       switch( $_FILES['upload']['error'] )
       {
           case 0: echo"0"; break;
           case 1: echo"1"; break;
           case 2: echo"2"; break;
           case 3: echo"3"; break;
           case 4: echo"4"; break;
           case 5: echo"5"; break;
           case 6: echo"6"; break;
           case 7: echo"7"; break;

           default:    echo"not sure"; break;
       }
   }

Run a var_dump () on the $_FILES array, should give you (and us) more to work with.

Also, please post your actual form here, if you still can't figure it out after doing the above.

[BuildMyWeb]

got nothin:

 

array(0) { }

[Christian F.]

Well.. There's your problem.

[requinix]

Did you remember to include the enctype on the form?

[BuildMyWeb]

yes, enctype is there. and many files have been uploaded successfully. its this one instance that im having trouble. its an .exe file that client wants to be uploaded (despite my advising against that extension) of 128MBs. its the largest to-date so i thought maybe file size was the issue. smaller .exe files successfully upload as well. so i dont know where to go from here.

 

<form action='xxx.php' method='POST' enctype='multipart/form-data'>
<div class='form_text'>Document:</div> <div class='form_input'><input type='file' name='upload' /></div>
<div class='form_text'>File Name:</div> <div class='form_input'><input type='text' size='25' maxlength='25' name='file_name' /></div>

<div style='height:40px;'></div>

<div class='form_text'>Category:</div> <div class='form_input'><input type='text' size='25' maxlength='25' name='category' /></div>
<div class='form_text'>Destination:</div> <div class='form_input'><input type='radio' name='dest' value='priv' checked='checked'>Private<input type='radio' name='dest' value='pub'>Public</div>

<div style='height:40px;'></div>

<div class='submit_button'><input type='submit' value='Upload'/></div>
</form>

double check that the directives are being set correctly by running phpinfo()

thanks aykay. but i dont know what you mean by this

[Pikachu2000]

That's exactly what the OP did in the very first post.

[PFMaBiSmAd]

An empty $_FILES array is generally a symptom of exceeding the max_post_size setting. What does echoing $_SERVER['CONTENT_LENGTH'], on the line right before your if( $_FILES['upload']['error'] > 0 ) statement, show?

[AyKay47]

That's exactly what the OP did in the very first post.

 

Really? because I'm seeing output from a local php.ini file which I am not convinced is even in the right place to affect the script.

OP, place phpinfo in your script and post the output for the directives post_max_size and upload_max_filesize

[Pikachu2000]

Then you must not have even read the post.

[BuildMyWeb]

@ PFMaBiSmAd

 

content length = 127620926

[Pikachu2000]

Have you ever been able to upload anything with this script, or is it just this one file that's failing? You should probably post the rest of the code; there's something odd about all this.

[BuildMyWeb]

yes pikachu. i noted that a little earlier in the thread;

 

yes, enctype is there. and many files have been uploaded successfully. its this one instance that im having trouble. its an .exe file that client wants to be uploaded (despite my advising against that extension) of 128MBs. its the largest to-date so i thought maybe file size was the issue. smaller .exe files successfully upload as well. so i dont know where to go from here.

i have the form posted higher in the thread. here is the handler:

 

<?php
// START FUNCTIONS
   function clean_string( $string )
   {
       $string = trim( $string );
       $string = htmlentities( $string );

       return $string;
   }
   // END FUNCTIONS

   $file_name = clean_string( $_POST['file_name'] );
   $category = clean_string( $_POST['category'] );
   $dest_page = clean_string( $_POST['dest'] ); // priv or pub

   $rootDir = '/home/xxx/xxx/' . $dest_page . '/';

   //echo"content length = " . $_SERVER['CONTENT_LENGTH'];

   // if there is an error with file upload
   if( $_FILES['upload']['error'] > 0 )
   {
       switch( $_FILES['upload']['error'] )
       {
           case 1: echo"upload_max_filesize exceeded"; break;

[Pikachu2000]

OK, so that's the actual code for the form. How about posting the code that processes the form?

[PFMaBiSmAd]

I'm going to guess your web host has imposed a maximum post size limit on the sever that is independent of php's settings. Have you checked the web host's FAQ section or asked the web host?

ill try this. thank you.

[AyKay47]

Talk about not reading the post...

[Pikachu2000]

sorry i took this long to reply. cant get an error. this is what imm troubleshooting with and the response is without a value;

 

"error: "

 

if( $_FILES['upload']['error'] > 0 )
   {
       $error_msg = $_FILES['upload']['error'];
       echo"error: " . $error_msg;

       switch( $_FILES['upload']['error'] )
       {
           case 0: echo"0"; break;
           case 1: echo"1"; break;
           case 2: echo"2"; break;
           case 3: echo"3"; break;
           case 4: echo"4"; break;
           case 5: echo"5"; break;
           case 6: echo"6"; break;
           case 7: echo"7"; break;

           default:    echo"not sure"; break;
       }
   }

 

You say this code is outputting "error: ". AFAICT, it shouldn't output anything at all if the ['error'] index doesn't exist, except for maybe a undefined index notice. That's why I was saying something seems odd to me.

[AyKay47]

The only thing I can think of for the code Pikachu posted is that there are 8 possible values for $_FILES[]['error'] and the OP has 7 in the switch. But even so, $error_msg should output the error value, the default switch value should output as well, something. That's what initially jumped out at me as well when reading the code.

The echo is conditional upon the existence of $_FILES['[upload']['error']. The subsequent var_dump() shows an empty array. The conditional should return FALSE, and there should be no output at all.
