Good afternoon

I was trying to adapt a code I already had here to be able to by a watermark on a photo. But there's plenty of time I do not deal with html or php. So could you guys give me this help to fix the problem of selecting the correct .png (watermark) and even reformatting the code to make it simpler?

        $image_path = "avatares/branco.png";
    } elseif (isset($_POST['cor']) == "colorido") {
        $image_path = "avatares/colorido.png";
    } else {
        echo ":)";
    }

function watermark_image($oldimage_name, $new_image_name){
    global $image_path;
    list($owidth,$oheight) = getimagesize($oldimage_name);
    $width  = 800;
    $height = 800;

    $img_src = imagecreatefromjpeg($oldimage_name);

Dear, sorry, but I've come to a solution using a switch: D

The result looks like this:

<script src="http://deepliquid.com/Jcrop/js/jquery.Jcrop.min.js"></script><scriptsrc="js/jquery.Jcrop.js"></script>
<link rel="stylesheet" href="css/jquery.Jcrop.css" type="text/css" />

<?php

switch($_POST['cor']){
    case 'preto' : 
        $image_path = "avatares/preto.png";
        break;
    case 'branco':
        $image_path = "avatares/branco.png";
        break;
    case 'colorido':
        $image_path = "avatares/colorido.png";
        break;
    default:
        echo "Eita, deu erro";
}


function watermark_image($oldimage_name, $new_image_name){
    global $image_path;
    list($owidth,$oheight) = getimagesize($oldimage_name);
    $width  = 800;
    $height = 800;    
    $im = imagecreatetruecolor($width, $height);
    $img_src = imagecreatefromjpeg($oldimage_name);
    imagecopyresampled($im, $img_src, 0, 0, 0, 0, $width, $height, $owidth, $oheight);
    $watermark = imagecreatefrompng($image_path);
    list($w_width, $w_height) = getimagesize($image_path);        
    $pos_x = $width - $w_width; 
    $pos_y = $height - $w_height;
    imagecopy($im, $watermark, $pos_x, $pos_y, 0, 0, $w_width, $w_height);
    imagejpeg($im, $new_image_name, 100);
    imagedestroy($im);
    unlink($oldimage_name);
    return true;
}

$demo_image= "";
if(isset($_POST['createmark']) and $_POST['createmark'] == "Submit"){
    $path = "uploads/";
    $valid_formats = array("jpg","bmp","jpeg");

    if($upload_status){
        $new_name = $path.time().".jpg";
        if(watermark_image($path.$_FILES['imgfile']['name'], $new_name))
                $demo_image = $new_name;

    }
    }
    else
    $msg = "A foto tem que ter menos que 2,5mb.";
    }
}

You made a little confusion when using the "isset ()" function. It checks whether the variable has already been defined and the result is boolean (true or false).

I suppose you want the following:

if(isset($_POST['cor']) {
    switch ($_POST['cor']) {
        case 'preto':
            $image_path = "avatares/preto.png";
            break;
        case 'branco':
            $image_path = "avatares/branco.png";
            break;
        case 'colorido':
            $image_path = "avatares/colorido.png";
            break;
        default:
            echo ":)";
    }
}
