表单输入数组$ _GET逗号分隔的网址 [英] Form input array $_GET comma separated in URL
问题描述
我有一个表格：
<form action="results.php" method="get">
<select name="genres[]">
<option value="jazz"></option>
<option value="blues"></option>
<option value="rock"></option>
</select>
</form>
提交表单，输入变得URL后 example.com/?genres%5B%5D=jazz&genres%5B%5D=blues&genres%5B%5D=rock
下一步，它看起来并不很漂亮，我在我的形式有多种输入（与约18流派），所以如果用户选择了很多，URL变得很长。我想它变成/？流派=爵士乐，蓝调，摇滚
Next to that it doesn't look very nice, I have multiple inputs in my form (and around 18 genres) so if a user selects a lot, the URL becomes very long. I'd like it to become /?genres=jazz,blues,rock
现在我读过这篇文章，但它没有说明如何进行清洁的URL。下一步，我不得不使用输入作为一个数组，如 $流派= $ _GET ['风格'] 在其他功能使用。
Now I've read this post, but it doesn't state how to make the cleaner URL. Next to that, I have to use the input as an array, eg $genres = $_GET['genres'] to use in another function.
推荐答案
您可以做到这一点是这样的：
you can do it like this:
<!doctype html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script>
$(document).ready(function(){
$("#go").click(function(){
var g = $("#genres").val();
var href = 'results.php?genres=';
if(g != null) {
href += g;
}
document.location.href=href;
});
});
</script>
</head>
<body>
<select id="genres" size="3" multiple>
<option value="jazz">jazz</option>
<option value="blues">blues</option>
<option value="rock">rock</option>
</select>
<input type="button" value="go" name="submit" id="go">
</body>
</html>
在results.php你应该：
in results.php you should:
$g = isset($_GET['genres'])?$_GET['genres']:"";
$genres = explode(",",$g);
我有形式完全删除，因为流派现在由 document.location.href 发送。 jQuery的的 .VAL（）函数返回像预期（由崩盘，）
i have removed the form completely because the genres are now sent by document.location.href. The .val() function of jquery returns the selected values like expected (imploded by ,)
