How to upload & Save Files with Desired name
You can try this,
$info = pathinfo($_FILES['userFile']['name']);$ext = $info['extension']; // get the extension of the file$newname = "newname.".$ext; $target = 'images/'.$newname;move_uploaded_file( $_FILES['userFile']['tmp_name'], $target);
This would work very well --You can use HTML5 to allow only image files to be uploaded.This is the code for uploader.htm --
<html> <head> <script> function validateForm(){ var image = document.getElementById("image").value; var name = document.getElementById("name").value; if (image =='') { return false; } if(name =='') { return false; } else { return true; } return false; } </script> </head> <body> <form method="post" action="upload.php" enctype="multipart/form-data"> <input type="text" name="ext" size="30"/> <input type="text" name="name" id="name" size="30"/> <input type="file" accept="image/*" name="image" id="image" /> <input type="submit" value='Save' onclick="return validateForm()"/> </form> </body></html>Now the code for upload.php --
<?php $name = $_POST['name'];$ext = $_POST['ext'];if (isset($_FILES['image']['name'])){ $saveto = "$name.$ext"; move_uploaded_file($_FILES['image']['tmp_name'], $saveto); $typeok = TRUE; switch($_FILES['image']['type']) { case "image/gif": $src = imagecreatefromgif($saveto); break; case "image/jpeg": // Both regular and progressive jpegs case "image/pjpeg": $src = imagecreatefromjpeg($saveto); break; case "image/png": $src = imagecreatefrompng($saveto); break; default: $typeok = FALSE; break; } if ($typeok) { list($w, $h) = getimagesize($saveto); $max = 100; $tw = $w; $th = $h; if ($w > $h && $max < $w) { $th = $max / $w * $h; $tw = $max; } elseif ($h > $w && $max < $h) { $tw = $max / $h * $w; $th = $max; } elseif ($max < $w) { $tw = $th = $max; } $tmp = imagecreatetruecolor($tw, $th); imagecopyresampled($tmp, $src, 0, 0, 0, 0, $tw, $th, $w, $h); imageconvolution($tmp, array( // Sharpen image array(−1, −1, −1), array(−1, 16, −1), array(−1, −1, −1) ), 8, 0); imagejpeg($tmp, $saveto); imagedestroy($tmp); imagedestroy($src); }}?>
