Multiupload from API

aladdin · Jul 6, 2013

Can you set an example for the multiupload images from your computer and URL-links? This requires a flash?

Version 2.5.8

Danny.Domb · Jul 6, 2013

Hello,

If I understand you correctly, you want to upload multiple files using the API?

Well, you shouldn't, simply because it will be slower than simply starting a thread for each selected image.
That way, you will upload multiple files, calling multiple time the server. It is simpler, and easier.

aladdin · Jul 6, 2013

Yes you correctly understand me.
The standard interface, this function works fine, but i do not understand how to do it via the API.
This API upload one image from comp

PHP:

if (isset($_POST['submit']))
{
           
           
 
list($width, $height, $type, $attr) = getimagesize($_FILES['upload']['tmp_name']);
 
 
    //set POST variables
    $url = 'http://mysite.com/api';
       
    $fields = array(
                        'key' => urlencode('rebill_api'),
                        'upload' => base64_encode(file_get_contents($_FILES['upload']['tmp_name'])),
                        'format' => urlencode('txt')
                    );
 
if($width>1920) $fields['resize_width'] = 1920;
 
    //open connection
    $ch = curl_init();
 
 
 
    //set the url, number of POST vars, POST data
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, sizeof($fields));
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 240);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect: '));
 
    //execute post
   
    $result = curl_exec($ch);
   
if (!in_array($type, array('1', '2', '3')))
    {
        echo '<SCRIPT LANGUAGE="JavaScript">alert("Only PNG, JPG, JPEG or GIF");</SCRIPT>';
        exit;
    }
    if ($result=="too big")
    {
        echo '<SCRIPT LANGUAGE="JavaScript">alert("MAX 2Mb");</SCRIPT>';
        exit;
    }
   
    //close connection
print"".$result."";
    curl_close($ch);
 
}

and from URL

PHP:

if (isset($_POST['submit_url']))
{

list($width, $height, $type, $attr) = getimagesize($_POST['upload2']);



    //set POST variables
    $url = 'http://mysite.com/api';
    $fields = array(
                        'key' => urlencode('rebill_api'),
                        'upload' => $_POST['upload2'],
                        'format' => urlencode('txt')
                    );
if($width>1920) $fields['resize_width'] = 1920;

    //open connection
    $ch = curl_init();

    //set the url, number of POST vars, POST data
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, sizeof($fields));
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 240);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect: '));

    //execute post
    
    $result = curl_exec($ch);
    if (!in_array($type, array('1', '2', '3'))) 
    {
        echo '<SCRIPT LANGUAGE="JavaScript">alert("Only PNG, JPG, JPEG or GIF");</SCRIPT>';
        exit;
    }
    if ($result=="too big") 
    {
        echo '<SCRIPT LANGUAGE="JavaScript">alert("Max 2Mb");</SCRIPT>';
        exit;
    }
    
print"".$result."";

    //close connection
    curl_close($ch);

}

Upload form is

HTML:

<script>
function doGet() {
document.getElementById("uploading").style.display="inline";
document.getElementById("f_up").style.display="none";

}
</script>
<form NAME="stockForm" action="upload.php" method="post" enctype="multipart/form-data" style="margin:0; padding:0">

From comp
<table cellpadding="0" cellspacing="3" width="100%" border="0">
                    <tr valign="bottom">
                        <td>
                            <input type="file" size="30" name="upload" />
                            <br />

                        </td>
                        <td align="right"><input type="submit" class="button" name="submit" onclick="doGet();" value="Upload"  style="width:70px" /></td>
                    </tr>
                    </table>
From URL
<table cellpadding="0" cellspacing="3" width="100%" border="0">
                    <tr valign="bottom">
                        <td>

                            <br />

                        </td>
                        <td align="right">
                        
                        <input type="submit" class="button" name="submit_url" onclick="doGet();" value="Загрузить" style="width:70px" />
                        </td>
                    </tr>
                    </table>
</form>

For multiupload i need to use flash? or not? How i can do it?

Danny.Domb · Jul 6, 2013

No you do not need flash, flash is used to support older browsers like IE 8.

First of all, you must tell html that you want to allow multiple files, so

HTML:

<input type="file" size="30" name="upload" />

Should be :

HTML:

<input type="file" size="30" name="upload[]" />

Now, when you will receive your $_FILES variable in php, instead of having a string for the value of tmp_name or others variables, you will receive an array

So instead of

PHP:

$_FILES['upload']['tmp_name']

it should be

PHP:

$_FILES['upload']['tmp_name'][0]

and from there, you may loop the array and send a curl request for each items.

I hope it answer your question,
Danny

Rodolfo · Jul 6, 2013

You need to iterate the files object.

Cheers,

aladdin · Jul 7, 2013

Danny.Domb, tnx I will try this.
Rodolfo, that is?

partially yes

Upload from comp works fine

PHP:

<script>
function doGet() {
document.getElementById("uploading").style.display="inline";
document.getElementById("f_up").style.display="none";
 
}
</script>
<form NAME="stockForm" action="upload.php" method="post" enctype="multipart/form-data" style="margin:0; padding:0">
 
From comp
<table cellpadding="0" cellspacing="3" width="100%" border="0">

<br />
 
</td>
<td align="right"><input type="submit" class="button" name="submit" onclick="doGet();" value="Upload" style="width:70px" /></td>
</tr>
</table>
From URL
<table cellpadding="0" cellspacing="3" width="100%" border="0">

</td>

</form>
<?
if (isset($_POST['submit']))
{

Uploads from URL i will do the same, but i do not understand how to connect the Ajax as a demo? How better to use multiple URLs. PLZ

Can i use standart function in API? And How?

Rodolfo · Jul 10, 2013

Each time you need to upload multiple files you must iterate that request. In the default website Chevereto issues a request for each URL, each file, etc. So if you have 5 files selected you must run the request 5 times, one single time for each file or parallel.

aladdin · Dec 2, 2013

Hello, how to activate standart multiupload protection in API functions?

$config['max_uploads_per_minute'] = 10; // Default: 15
$config['max_uploads_per_hour'] = 30; // Default: 30
$config['max_uploads_per_day'] = 50; // Default: 50
$config['max_uploads_per_week'] = 200; // Default: 200
$config['max_uploads_per_month'] = 500; // Default: 500

Rodolfo · Dec 2, 2013

Just overwrite those limits in api.php

aladdin · Dec 3, 2013

Exactly where and how it should overwrite? How?

Increase all the limits. Minute, hour, etc.

aladdin · Dec 4, 2013

what it means to be increased? How and why?

Rodolfo · Dec 4, 2013

It means go from 10 to 1000 or some. Increase the limits.

aladdin · Dec 4, 2013

But I do not need 1000 uploads per minute.
I need 10 per minute, 30 per hour, 50 per day, etc.
What should I do? Please give me exact code. Thanks.

Rodolfo · Dec 5, 2013

Ok but the API is the same for every API request so if you have 2 clients they will share the limits. Get it?

aladdin · Dec 5, 2013

Yes, I understand. I only need to do limit for API as in default on web interface.

Rodolfo · Dec 5, 2013

Just for the api.

Multiupload from API
