Discuz! 增加允许上传的图片格式
打开 source/class/discuz/discuz_upload.php 文件，查找：static $imgext= array('jpg', 'jpeg', 'gif', 'png', 'bmp');修改为：
static $imgext= array('jpg', 'jpeg', 'gif', 'png', 'bmp', 'svg');接着将第 107到130 行的
function get_image_info($target, $allowswf = false) {
$ext = discuz_upload::fileext($target);
$isimage = discuz_upload::is_image_ext($ext);
if(!$isimage && ($ext != 'swf' || !$allowswf)) {
return false;
} elseif(!is_readable($target)) {
return false;
} elseif($imageinfo = @getimagesize($target)) {
list($width, $height, $type) = !empty($imageinfo) ? $imageinfo : array('', '', '');
$size = $width * $height;
if((!getglobal('setting/imagelib') && $size > (getglobal('setting/gdlimit') ? getglobal('setting/gdlimit') : 16777216)) || $size < 16 ) {
return false;
} elseif($ext == 'swf' && $type != 4 && $type != 13) {
return false;
} elseif($isimage && !in_array($type, array(1,2,3,6,13))) {
return false;
} elseif(!$allowswf && ($ext == 'swf' || $type == 4 || $type == 13)) {
return false;
}
return $imageinfo;
} else {
return false;
}
}修改为：
function get_image_info($target, $allowswf = false) {
$ext = discuz_upload::fileext($target);
$isimage = discuz_upload::is_image_ext($ext);
if(!$isimage && ($ext != 'swf' || !$allowswf)) {
return false;
} elseif(!is_readable($target)) {
return false;
} elseif($imageinfo = @getimagesize($target)) {
list($width, $height, $type) = !empty($imageinfo) ? $imageinfo : array('', '', '');
$size = $width * $height;
if((!getglobal('setting/imagelib') && $size > (getglobal('setting/gdlimit') ? getglobal('setting/gdlimit') : 16777216)) || $size < 16 ) {
return false;
}
return $imageinfo;
} else {
return false;
}
}然后再打开 source/function/function_upload.php 文件，将第 22 行修改为：
$imageexts = array('jpg','jpeg','gif','png','bmp','webp');
