PHP折腾笔记

Finally have a multi-language plugin installed, which Can’t be run without a fancy switching button. I photoshopped an old school pink neon sign, with color picked from Drive =D 多语言达成！所以没有一个漂亮的切换图标怎么行？做了一个old school的粉色霓虹灯, 色彩取的 Drive 上的=D
Learned some CSS for composition. Basically have a div position=absolution covered by a div position=relative to make it floating above content while have relative position. Url is a bitch, I originally want to use cookie for switching so can get rid of ?lang=xxx. Yet the plugin(qTranslate) doesn’t offer this function. It would kill me if I want to code it myself so I have to deal with the URL parameters. I stole someone’s function for updating parameters from php url:
[php]
function addURLParameter ($url, $paramName, $paramValue) {
$url_data = parse_url($url);
$params = array();
parse_str($url_data[‘query’], $params);
$params[$paramName] = $paramValue;
$params_str = http_build_query($params);
return http_build_url($url, array(‘query’ => $params_str));
}
[/php]
Do judge
[php]
<?php
$currentURL=get_option(‘home’).$_SERVER[‘REQUEST_URI’] ;
if($lang==” || $lang==’cn’) {
$targetURL=addURLParameter($currentURL,’lang’,’en’);
echo "<a href=" . $targetURL ."><img src=’./uploads/pics/blog_lang_en.png’ height=82 w=206 /></a>";
}
else {
$targetURL=addURLParameter($currentURL,’lang’,’cn’);
echo "<a href=" . $targetURL ."><img src=’./uploads/pics/blog_lang_zh.png’ height=82 w=161 /></a>";
}
?>
[/php]
And the website was down… Turned out http_build_url() is from PECLibrary not standard one, so use this instead:
[php]
function build_url($url_data) {
$url="";
if(isset($url_data[‘host’]))
{
$url .= $url_data[‘scheme’] . ‘://’;
if (isset($url_data[‘user’])) {
$url .= $url_data[‘user’];
if (isset($url_data[‘pass’])) {
$url .= ‘:’ . $url_data[‘pass’];
}
$url .= ‘@’;
}
$url .= $url_data[‘host’];
if (isset($url_data[‘port’])) {
$url .= ‘:’ . $url_data[‘port’];
}
}
$url .= $url_data[‘path’];
if (isset($url_data[‘query’])) {
$url .= ‘?’ . $url_data[‘query’];
}
if (isset($url_data[‘fragment’])) {
$url .= ‘#’ . $url_data[‘fragment’];
}
return $url;
}
[/php]
Yuppieeee, it does look good to me. So happy to brag my language skills =P
排版看了下CSS，一个div position=absolute套在一个div position=relative里就可以浮在内容上面了。链接很伤脑筋，本来想通过cookie切换这样URL看起来漂亮点没有?lang=xxx，但是插件（qtranslate）没提供这个，我又不会php就不兴起这么可怕的自己写的念头了.. 至于php的参数，试了下手动编辑弄的想死，显然不是科学的方法，所以搜了下偷别人的函数用

[php]
function addURLParameter ($url, $paramName, $paramValue) {
$url_data = parse_url($url);
$params = array();
parse_str($url_data[‘query’], $params);
$params[$paramName] = $paramValue;
$params_str = http_build_query($params);
return http_build_url($url, array(‘query’ => $params_str));
}
[/php]
然后判断下
[php]
<?php
$currentURL=get_option(‘home’).$_SERVER[‘REQUEST_URI’] ;
if($lang==” || $lang==’cn’) {
$targetURL=addURLParameter($currentURL,’lang’,’en’);
echo "<a href=" . $targetURL ."><img src=’./uploads/pics/blog_lang_en.png’ height=82 w=206 /></a>";
}
else {
$targetURL=addURLParameter($currentURL,’lang’,’cn’);
echo "<a href=" . $targetURL ."><img src=’./uploads/pics/blog_lang_zh.png’ height=82 w=161 /></a>";
}
?>
[/php]
然后网站被玩坏掉了.. 一番【基本靠猜】的debug后发现http_build_url()是什么PECL包里的，就是不是标准库，于是用了下面那个（之前没注意因为不知道PECL是啥）
[php]
function build_url($url_data) {
$url="";
if(isset($url_data[‘host’]))
{
$url .= $url_data[‘scheme’] . ‘://’;
if (isset($url_data[‘user’])) {
$url .= $url_data[‘user’];
if (isset($url_data[‘pass’])) {
$url .= ‘:’ . $url_data[‘pass’];
}
$url .= ‘@’;
}
$url .= $url_data[‘host’];
if (isset($url_data[‘port’])) {
$url .= ‘:’ . $url_data[‘port’];
}
}
$url .= $url_data[‘path’];
if (isset($url_data[‘query’])) {
$url .= ‘?’ . $url_data[‘query’];
}
if (isset($url_data[‘fragment’])) {
$url .= ‘#’ . $url_data[‘fragment’];
}
return $url;
}
[/php]
折腾了一中午达到了略骚包的效果，我很满意。
