CheckScript

battlewizz

Hi There,

i want to let uploadify check if a file i already on the server or not. So I implemented uploadify like this:

<script type=\"text/javascript\" src=\"source/uploadify/jquery-1.3.2.min.js\"></script>
<script type=\"text/javascript\" src=\"source/uploadify/jquery.uploadify.js\"></script>
<script type=\"text/javascript\">

$(document).ready(function() {
	$('#upload').fileUpload({
		'uploader': 'source/uploadify/uploader.swf',
		'script': 'source/uploadify/upload.php',
		'checkScript' : 'source/uploadify/check.php',
		'folder': 'source/banners',
		'cancelImg': 'source/uploadify/cancel.png',
		'multi' : true,
		'auto' : true,
		'buttonText' : 'DURCHSUCHEN',
		'displayData' : 'percentage',
		'onComplete' : function(event, queueID, fileObj, response, data) {
			$('div#status').append(\"Datei hochgeladen: \" + fileObj.name + \" <br />\");
		}
	});
});

</script>

But now the upload does not start. I'm using the uploadify check.php. Now, can you tell me what I'm doing wrong?

Thanks and greetings

Hi battlewizz,

I just checked your code and it worked fine for me, but of course I couldn't check your paths - so doublecheck them and also check the id of the FileUpload in the input


<input name=\"fileUpload\" id=\"upload\" type=\"file\" />

battlewizz

Hi,

thanks for the quick reply. I checked the paths but they are all correct. I can open the check.php if i paste the path into my browser adress bar. But that does'nt stop the script from not working.

Here's the html I'm using right now:

<body>

<h1>foo bar</h1>

<div id=\"uploadbox\">
<input name=\"fileUpload\" id=\"upload\" type=\"file\" />
</div>

<div id=\"status\"></div>

</body>

Try adding the onError sample code I posted to the thread "Some questions". It will output the starting folder your relative path needs to start from.

battlewizz

Okay, i added the onError-Code from your post, but the results stay the same. There is no alert triggered and the script stops with this screen:

What is your HTML element code?

This one's has me stumped. I recreated the folder structure you have used, and I was able to upload multiple files without a problem. My only thought is server settings. Check this post http://www.uploadify.com/forum/viewtopic.php?f=7&t=13.

battlewizz

To be honest, I don't think that this has something do do with the server settings you mentioned. The thing is, if I delete the checkScript Option from the Code, the upload works perfectly fine, and I'm able to upload as many files at the same time as i want. But then I can't check if the files already exist...

TravisN.

If you download the "Uploadify Sample Collection" from the downloads section, and run the second sample down do you still get the error?

TravisN.

I just tested putting in a wrong path into the checkScript option, and I get the same result you are experiencing. Do one or two things.

1. Double check your relative paths
2. Compress you folder structure including all js, css etc files, attach it to a post and I'll have a look.

I ran the second example and, yeah, it's still the same. It stops before uploading. Seems like the problem does come from the server, but what can it be? Some falsely set user rights? I still attached my folder structure so you can have look.

Battlewizz

TravisN.

hmmm. It is looking like server settings. I copied your folder setup to my server and all ticked over without a problem.

Let's have a look at
1. what OS is your sever
2. is your server local
3. what are your php.ini settings - can you upload it so I can compare
4. you said that if you remove the checkScript option it runs perfectly. But have the files actually uploaded?

Hi, Sorry for the late answer.

1. Linux (RedHat)
2. No
3. i attached my php.ini (now it should be attached, sorry)
4. Yeah, the files uploaded perfectly

Hope this helps...

TravisN.

Here's the main differences between my php.ini and yours

                   mine    yours
max_input_time      -1      60    -maximum time post and get scripts can send data (-1 = unlimited)
memory_limit         124M   40M   -should be greater than post_max_size

and this, but I don't think this would have any effect. Worth a try though
register_argc_argv   On     Off   -Used for sending GET values across scripts

There were others but nothing that relates to scripts. Try changing these values.

TravisN.

Also check to see if json is enabled. This isn't set in the php.ini. To check it create a new php file and put in phpinfo();
when you run the page do a search for json. It needs to say enabled.

Chances are your server is running PHP 4 - the check.php script uses a

json_encode

function which is only included natively in PHP 5 - I had this problem as well. To solve this solution, you can either upgrade your PHP version or you can download a JSON.php file compatible with PHP 4 and include it in check.php before the encode call. Hope this helps.

That's it, thanks a lot.

I included the following code in the check.php:

<?php
if (!function_exists('json_encode'))
{
  function json_encode($a=false)
  {
    if (is_null($a)) return 'null';
    if ($a === false) return 'false';
    if ($a === true) return 'true';
    if (is_scalar($a))
    {
      if (is_float($a))
      {
        // Always use \".\" for floats.
        return floatval(str_replace(\",\", \".\", strval($a)));
      }

      if (is_string($a))
      {
        static $jsonReplaces = array(array(\"\\\", \"/\", \"\n\", \"\t\", \"\r\", \"\b\", \"\f\", '\"'), array('\\\\', '\\/', '\\n', '\\t', '\\r', '\\b', '\\f', '\\"'));
        return '\"' . str_replace($jsonReplaces[0], $jsonReplaces[1], $a) . '\"';
      }
      else
        return $a;
    }
    $isList = true;
    for ($i = 0, reset($a); $i < count($a); $i++, next($a))
    {
      if (key($a) !== $i)
      {
        $isList = false;
        break;
      }
    }
    $result = array();
    if ($isList)
    {
      foreach ($a as $v) $result[] = json_encode($v);
      return '[' . join(',', $result) . ']';
    }
    else
    {
      foreach ($a as $k => $v) $result[] = json_encode($k).':'.json_encode($v);
      return '{' . join(',', $result) . '}';
    }
  }
}
?>

and now it works fine. The good thing is that the code is upwards compatible, so if i get upgraded to PHP 5.2 or higher, the native json functions will be used instead of the custom ones. Problem solved.
