Upload Via url

[NewGuy21]

Ok I finally finished my image host. But I wanna add option to upload via url.

 

I have this as the form

<FORM ENCTYPE="multipart/form-data" ACTION="upload.php" METHOD=POST>
<table width="100%" border="0" cellpadding="2" cellspacing="0" align="center">
<tr>
	<td align="right" valign="top"><span class="body"><strong>Your File:</strong></span></td>
	<td align="left"><input type="File" name="thefile" size="30" maxlength="255"></td>
</tr>

 

It was trying to add a radial button. So you can add via url.

 

But when I add the radial it doesnt work.

 

Here is the copy of the php that  uploads the file.

 

<?

// get variables for fields on upload screen
$thefile = $_FILES['thefile'];

	$query = "select ip from blocked where ip = '$currentip'";
    $result = mysql_query($query) or die("Query failed.");
	$num_rows = mysql_num_rows($result);
	if ($num_rows > 0) {
		$messages .= "Your IP address (" . $currentip . ") has been blocked from using this service.<br><br>";
	}
}

// check for a file
if (!isset($thefile) || $thefile['name'] == "") {
	$messages .= "You must select a file to upload using the "Browse" button.<br><br>";

	}

	// check for valid file size

I found this code to upload via url.

 

<?php
if ($_GET[xfer]) {
if ($_POST[from] == "") {
print "You forgot to enter a url.";
} else {
copy("$_POST[from]", "$_POST[to]");
$size = round((filesize($_POST[to])/1000000), 3);
print "transfer complete.<br>
<a><a href=\"$_POST[from]\">$_POST[from]</a><br>
<a><a href=\"$_POST[to]\">$_POST[to]</a> : $size MB";
}
} else {
print "<form action=\"$PHP_SELF?xfer=true\" method=post>
from(http://): <input name=from><br>
to(filename): <input name=to><br>
<input type=submit value=\"transload\">";
}
?>

 

So im trying to incorporate into what ive already done. I would greatly appreciate it if someone could help me.

 

Thank you ahead of time

I'm confused.. Can you explain what you mean by 'radial button' and 'upload via url'? Can you also give more detail about what is happening when you try to use your code? 'doesn't work' isn't much help

 

[NewGuy21]

Adding a radial button similar to the one on imageshack.us.

 

They have 3 radial buttons above the upload imput.

 

I was just gonna add one additional radial. To upload an image via url. Instead of acctually downloading the file then uploading it, you just put in the addy of the image and it uploads it.

 

Thats what im trying to do.

 

And when I say doesnt work, I mean i cant incorporate it into the code I already have. I dont know how to do it really. I mean I tried editing my code and it just completely broke it. I ran it through my php debugger and had so many errors was crazy.

 

So im asking for help on how to do this.

[phast1]

Ahh, those are 'radio' buttons, not radial

 

First you need to add the radio buttons to your form and assign them a name, then you would need to modify the PHP file that the form submits to so that it checks for the value of the radio buttons and either runs your normal code (assuming it works) to process the uploaded file or runs new code to save a URL image instead of an uploaded one.. Saving the URL image can be done using fsockopen() and fread() functions to read in the image, and then use the fopen() and fwrite() functions to save the data to disk.. You could also save the image into a database instead of writing it to disk..

 

Does that help?

 

[NewGuy21]

A lil but how do I exactly add the code for the url into my other code. Thats the problem im having. I have no problem making the lil button with the checks. Just I dont know exactly how to incorporate it into my other code.

[phast1]

If you are not sure how to check the value of the radio buttons in the PHP code, it would be something like this:

 

if ($_POST['radio_name'] == 'url') {
  // put code here to process a url submission
} else {
  // put your original code here to process regular file submissions
}

 

Note that your form is also going to need a regular text input field for people to type in the URL.. Your example of imageshack.us has this extra field too, but they are using javascript to try and make it seem like only one field by hiding the file input box if you select 'URL' and vice-versa..

 

If you aren't sure what to do to process the url submission, then you should probably read up on fsockopen(), fread(), and fwrite(), since those are pretty much the only functions you need to use in order to accomplish this..

Ty. I think I have started to figure it out I found this base code. From guy named Nico.

function transload()
        {
                if (ini_get('allow_url_fopen') == 0)
                {
                        $this->set_error($this->default_errors[15]);
                        return false;
                }
       
                if (!$this->is_valid_upload_path())
                {
                        return false;
                }
        
                if (!empty($this->transload))
                {
                        $filename = basename($this->transload);
                        $contents = '';
                       
                        if (!$this->is_valid_file($filename, false))
                        {
                                return false;
                        }

                        set_time_limit(0);
                        @ini_set('user_agent', 'PHP');

                        if (!($fp = @fopen($this->transload, 'rb')))
                        {
                                $this->set_error($this->default_errors[14]);
                                return false;
                        }
                       
                        while (!feof($fp))
                        {
                                $contents .= fread($fp, 8192);
                               
                                if ($this->max_size AND (strlen($contents) > $this->max_size))
                                {
                                        $this->set_error(sprintf($this->default_errors[9], $this->max_size));
                                        return false;
                                }
                        }
                       
                        fclose($fp);
       
                        if ($upload = @fopen($this->upload_path . $this->subdir . $this->rand_name($filename), 'w'))
                        {
                                fwrite($upload, $contents);
                                fclose($upload);
                        }
                       
                        $this->uploaded_files[] = $filename;
                        return true;
                }
        }

 

Now the problem Im having is getting the url through that code... to my other code

 

// get variables for fields on upload screen
$thefile = $_FILES['thefile'];
$tos = $_POST['tos'];

$currentip = $_SERVER['REMOTE_ADDR'];
$messages = "";

 

But ty so much you have helped me alot
