好吧所以问题似乎是在没有创建图像的函数中,或者在自身的脚本中没有将图像传递给函数
这是上传脚本(注意:这是注入AJAX)
$path = "cache/";
$valid_formats = array("jpg", "png", "gif", "jpeg");
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST")
{
$name = $_FILES['photoimg']['name'];
$size = $_FILES['photoimg']['size'];
if(strlen($name))
{
ist($txt, $ext) = explode(".", $name);
if(in_array($ext,$valid_formats))
{
if($size<(2024*2024))
{
$new_file = "header.".$ext;
$tmp = $_FILES['photoimg']['tmp_name'];
if(move_uploaded_file($tmp, $path.$new_file))
{
echo "<img src='cache/".$new_file."?".time()."' class='preview'>";
createHeader($new_file);
}
else
echo "failed";
}
else
echo "Image file size max 1 MB";
}
else
echo "Invalid file format..";
}
else
echo "Please select image..!";
exit;
}
现在这里是函数
function createHeader($new_file) {
$path = "uploads/";
$image = "cache/";
$width = 800;
if(preg_match('/[.](jpg)|(jpeg)$/', $new_file)) {
$im = imagecreatefromjpeg($image . $new_file);
} else if (preg_match('/[.](gif)$/', $new_file)) {
$im = imagecreatefromgif($image . $new_file);
imagecolortransparent($im, black);
} else if (preg_match('/[.](png)$/', $new_file)) {
$im = imagecreatefrompng($image . $new_file);
}
imagealphablending($im, false);
imagesavealpha($im, true);
$ox = imagesx($im);
$oy = imagesy($im);
$nx = $width;
$ny = floor($oy * ($width / $ox) );
imagecopyresampled($nm, $im, 0,0,0,0,$nx,$ny,$ox,$oy);
imagealphablending($im, true);
if(!file_exists($path)) {
if(!mkdir($path)) {
die("There was a problem. Please try again!");
}
}
imagejpeg($nm, $path . $new_file, 100);
imagedestroy($im);
imagedestroy($nm);
}
在逻辑中,代码必须做的是,如果用户使用我的cms,他或她可以通过单击一个图标来更改页面上的标题,该图标将使jQuery调用edit.php传递所需的查询字符串。从那里,用户可以上传一个新图像,该图像将被重命名为header.jpg并覆盖原始图像
header.jpg必须上传到uploads /目录中,并且原始图像缓存的副本应该是未链接的,函数可以创建副本并将其放入uploads /目录。
发生的事情是第一个脚本正在上传文件并将其放入缓存/目录,但该功能似乎不起作用,并且对上传/目录没有任何作用。
任何想法我可能做错了或不这样做都会导致这个烦人的问题?
