Post array of multiple checkbox values
提问by jjclarkson
Why is only one value of the "db" checkbox values array being sent to the server side script?
为什么“db”复选框值数组中只有一个值被发送到服务器端脚本？
JQUERY:
查询：
$(".db").live("change", function() {
$(this).add($(this).next("label")).add($(this).next().next("br")).remove().insertAfter(".db:last + label + br");
var url = "myurl.php";
var db = [];
$.each($('.db:checked'), function() {
db.push($(this).val());
});
if(db.length == 0) {
db = "none";
}
$.post(url, {db: db}, function(response) {
$("#dbdisplay").html(response);
});
return true;
});
HTML:
HTML：
<input type="checkbox" name="db[]" class="db" value="track"/><label for="track">track</label></br>
<input type="checkbox" name="db[]" class="db" value="gps"/><label for="gps">gps</label></br>
<input type="checkbox" name="db[]" class="db" value="accounting"/><label for="accounting">accounting</label></br>
Edit: I ended up answering my own question, but does anyone have documentation (or an explanation) of why this is necessary? It was difficult for me to find the exact answer (thus the posthumous post).
编辑：我最终回答了我自己的问题，但有没有人有文档（或解释）说明为什么这是必要的？我很难找到确切的答案（因此是死后的帖子）。

I agree with @jjclarkson. Just to add, instead of pushing your ids to an array, you can use $.map:
我同意@jjclarkson。只是添加，而不是将您的 id 推送到数组，您可以使用$.map：
$(".db").live("change", function() {
$(this).add($(this).next("label")).add($(this).next().next("br")).remove().insertAfter(".db:last + label + br");
var url = "myurl.php";
var db = $('.db:checked').map(function(i,n) {
return $(n).val();
}).get(); //get converts it to an array
if(db.length == 0) {
db = "none";
}
$.post(url, {'db[]': db}, function(response) {
$("#dbdisplay").html(response);
});
return true;
});

var checkeditems = $('input:checkbox[name="review[]"]:checked')
.map(function() { return $(this).val() })
.get()
.join(",");
$.ajax({
type: "POST",
url: "/index.php/openItems/",
data: "ids=" + checkeditems,
success: function(msg) { $(".mainContainer").html(msg); }
});

You need to have the square brackets to specify an array [] on the submitted variable name.
您需要使用方括号在提交的变量名称上指定数组 []。
{'db[]': db}
$(".db").live("change", function() {
$(this).add($(this).next("label")).add($(this).next().next("br")).remove().insertAfter(".db:last + label + br");
var url = "myurl.php";
var db = [];
$.each($('.db:checked'), function() {
db.push($(this).val());
});
if(db.length == 0) {
db = "none";
}
$.post(url, {'db[]': db}, function(response) {
$("#dbdisplay").html(response);
});
return true;
});

$('input[name="mycheckboxes"]:checked').map(function(){
return $(this).val();
}).get().join(",");
$('input[name="mycheckboxes"]:checked').map(function(){
return $(this).val();
}).get().join(",");
then explode in PHP
$mycheckboxes = explode(',',$_GET['mycheckboxes']);
然后在 PHP 中爆炸
$mycheckboxes = explode(',',$_GET['mycheckboxes']);
