    copied!<p>I wrote a script for uploading an image to my server. Users can use it e.g. for uploading their avatars, or their works.</p> <p>This is the function in functions.php</p> <pre><code>function save_image($image, $uploadedfile) { error_reporting(0); $change=""; $abc=""; define ("MAX_SIZE","40000"); function getExtension($str) { $i = strrpos($str,"."); if (!$i) { return ""; } $l = strlen($str) - $i; $ext = substr($str,$i+1,$l); return $ext; } $errors=0; if ($image) { $filename = stripslashes($image); $extension = getExtension($filename); $extension = strtolower($extension); if (($extension != "jpg") &amp;&amp; ($extension != "jpeg") &amp;&amp; ($extension != "png") &amp;&amp; ($extension != "gif")) { $change='&lt;div class="msgdiv"&gt;Unknown Image extension &lt;/div&gt; '; $errors=1; } else { $size=filesize($uploadedfile); if ($size &gt; MAX_SIZE*1024) { $change='&lt;div class="msgdiv"&gt;You have exceeded the size limit!&lt;/div&gt; '; $errors=1; } if($extension=="jpg" || $extension=="jpeg" ) { $uploadedfile = $uploadedfile; $src = imagecreatefromjpeg($uploadedfile); } else if($extension=="png") { $uploadedfile = $uploadedfile; $src = imagecreatefrompng($uploadedfile); } else { $src = imagecreatefromgif($uploadedfile); } echo $scr; list($width,$height)=getimagesize($uploadedfile); $newwidth=$width; $newheight=$height; $tmp=imagecreatetruecolor($newwidth,$newheight); imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height); $filename = "images/vcard_images/". $image; imagejpeg($tmp,$filename,100); imagedestroy($src); imagedestroy($tmp); imagedestroy($tmp1); }} } </code></pre> <p>So now I have a form on the page create.php where they can upload 6 of their works. So they select 6 files from their hard drive and then press save. Then I call the function 6 times like this:</p> <pre><code>$work1 = $_FILES["work1"]["name"]; save_image($_FILES["work1"]["name"], $_FILES['work1']['tmp_name']); $work2 = $_FILES["work2"]["name"]; save_image($_FILES["work2"]["name"], $_FILES['work2']['tmp_name']); $work3 = $_FILES["work3"]["name"]; save_image($_FILES["work3"]["name"], $_FILES['work3']['tmp_name']); $work4 = $_FILES["work4"]["name"]; save_image($_FILES["work4"]["name"], $_FILES['work4']['tmp_name']); $work5 = $_FILES["work5"]["name"]; save_image($_FILES["work5"]["name"], $_FILES['work5']['tmp_name']); $work6 = $_FILES["work6"]["name"]; save_image($_FILES["work6"]["name"], $_FILES['work6']['tmp_name']); </code></pre> <p>But the weird part is, if I press SAVE, the page just becomes white. And if I only call the function onces, so only this:</p> <pre><code>$work1 = $_FILES["work1"]["name"]; save_image($_FILES["work1"]["name"], $_FILES['work1']['tmp_name']); </code></pre> <p>It works perfectly fine.. </p> <p>No idea what I'm doing wrong..</p> <p>Kind regards</p> <p>EDIT:</p> <p>Error reporting told me this:</p> <pre><code>Notice: Constant MAX_SIZE already defined in /Applications/XAMPP/xamppfiles/htdocs/vcard2/user/functions.php on line 11 Fatal error: Cannot redeclare getExtension() (previously declared in /Applications/XAMPP/xamppfiles/htdocs/vcard2/user/functions.php:12) in /Applications/XAMPP/xamppfiles/htdocs/vcard2/user/functions.php on line 12 </code></pre>
