客户自己上传的图片大小不标准,想让传上来的图片统一变成150x113尺寸的。从网上搜到的程序在ie里用正常,到了别的浏览器(如搜狗浏览器等)就不行,这是什么原因?(感觉老是不执行)
代码如下:
$maxwidth) || ($maxheight && $height > $maxheight)){
if($maxwidth && $width > $maxwidth){
$widthratio = $maxwidth/$width;
$resizewidth=true;
}
if($maxheight && $height > $maxheight){
$heightratio = $maxheight/$height;
$resizeheight=true;
}
if($resizewidth && $resizeheight){
if($widthratio $ratio = $widthratio;
}else{
$ratio = $heightratio;
}
}elseif($resizewidth){
$ratio = $widthratio;
}elseif($resizeheight){
$ratio = $heightratio;
}
$newwidth = $width * $ratio;
$newheight = $height * $ratio;
if(function_exists(imagecopyresampled)){
$newim = imagecreatetruecolor($newwidth, $newheight);
imagecopyresampled($newim, $im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
}else{
$newim = imagecreate($newwidth, $newheight);
imagecopyresized($newim, $im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
}
imagejpeg ($newim,$name . .jpg);
imagedestroy ($newim);
}else{
imagejpeg ($im,$name . .jpg);
}
}
if(isset($_files['image']['size'])){
if($_files['image']['type'] == image/pjpeg){
$im = imagecreatefromjpeg($_files['image']['tmp_name']);
}elseif($_files['image']['type'] == image/x-png){
$im = imagecreatefrompng($_files['image']['tmp_name']);
}elseif($_files['image']['type'] == image/gif){
$im = imagecreatefromgif($_files['image']['tmp_name']);
}
if($im){
if(file_exists($filename.jpg)){
unlink($filename.jpg);
}
resizeimage($im,$resizewidth,$resizeheight,$filename); //生成小图
imagedestroy ($im);
echo 上传成功,图片文件名是:;
echo $myname..jpg;
}
}
//****************************************
}else{
echo ;
}
?>
回复讨论(解决方案) 你看看 product/min/ 目录下是否有生成的图片
ie ,firefox,chrome试试看,这三个行的话说明代码没问题。
