Using PHP and CURL to get image from remote url

Hello,

I need a PHP code that can get the image url from "$_POST['big_img']"(eg: http://i.dpstatic.com/misc/dps_logo.png) and more it to my server, and rename the image name to a random (eg: rand().dps.logo.png). The directory is /home/sharing/sub-domains/tuts/public_html/images/big/

 

I don't see why CURL should be a must. Here is my solution to your problem :

<?php
    $path = '/home/sharing/sub-domains/tuts/public_html/images/big/';
    if(isset($_POST['big_img']))
    {
        $image = file_get_contents(urldecode($_POST['big_img']));
        if($image !== false)
        {
            if(strpos($_POST['big_img'],"/") !== false)
            {
                $name = explode("/",$_POST['big_img']);
                $total = count($name);
                $handle = fopen($path.rand()."_".$name[$total-1],"w") or die("Could not create : ".$path.rand()."_".$name[$total-1]);
                if($handle !== false)
                {
                    fwrite($handle,$image);
                    fclose($handle);
                    echo 'The file has been successfully saved !';
                }
            }
        } else {
            echo 'Wrong path !';
        }
    }
?>

PHP:

 

My Host, doessn't allow file_get_contents

 

<?php
    $path = '/home/sharing/sub-domains/tuts/public_html/images/big/';
    if(isset($_POST['big_img']))
    {
        //$image = file_get_contents(urldecode($_POST['big_img']));
        $curl_handle=curl_init(urldecode($_POST['big_img']));
        curl_setopt($curl_handle, CURLOPT_NOBODY, true);
        $result = curl_exec($curl_handle);
        $retcode = false;
        if($result !== false)
        {
            $status = curl_getinfo($curl_handle, CURLINFO_HTTP_CODE);
            if($status == 200)
                $retcode = true;    
        }
        curl_close($curl_handle);
        
        if($retcode)
        {
            $curl_handle=curl_init();
            curl_setopt($curl_handle,CURLOPT_URL,urldecode($_POST['big_img']));
            curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2);
            curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1);
            $image = curl_exec($curl_handle);
            curl_close($curl_handle);
            
            if($image !== false)
            {
                if(strpos($_POST['big_img'],"/") !== false)
                {
                    $name = explode("/",$_POST['big_img']);
                    $total = count($name);
                    $handle = fopen($path.rand()."_".$name[$total-1],"w") or die("Could not create : ".$path.rand()."_".$name[$total-1]);
                    if($handle !== false)
                    {
                        fwrite($handle,$image);
                        fclose($handle);
                        echo 'The file has been successfully saved !';
                    }
                }
            }
        } else {
            echo 'File not found !';
        }
    }
?>

Hi,

I want this same functionality on submit of text box:
The image url will be input in this text box
How do I achieve the same?

<tr valign="top">
<th scope="row"><label><?php _e( 'External Image', 'testify' ) ?></label></th>
<td>
<input type="text" name="testify_meta[ext_image]" id="ext_image" value="<?php if( $project && !empty($meta['ext_image']) ) echo $meta['ext_image']; ?>" />


</td>
</tr>

<div class="testify-button"><input type="submit" name="save_project" value="<?php _e( 'Save Project', 'testify' ) ?>"></div>
<input type="hidden" name="project_id" value="<?php if ($project) echo $project->ID ?>">
</form>

</div>
