[英]How to retrieve data in a date range from mysql database in Laravel?
In my application, if someone clicks the Filter button I want to display data in a table format from mysql database, but here I am not receiving any responses.在我的应用程序中,如果有人单击“过滤器”按钮,我想以表格格式显示来自 mysql 数据库的数据,但在这里我没有收到任何响应。 Please someone help me out with this.
请有人帮我解决这个问题。
custom_script.js custom_script.js
fetch_data();
function fetch_data(from_date = '', to_date = '') {
if(from_date != '' && to_date != '') {
console.log(from_date+' | '+to_date)
}
}
$('#filter').click(function() {
var from_date = $('#from_date').val();
var to_date = $('#to_date').val();
if(from_date != '' && to_date != '') {
fetch_data(from_date, to_date);
}
else {
alert('Both Date is required');
}
});
$('#refresh').click(function() {
$('#from_date').val('');
$('#to_date').val('');
fetch_data();
});
HolidayController.php假日控制器.php
public function fetch_data(Request $request)
{
if($request->from_date != '' && $request->to_date != '') {
$data = DB::table('holidays')
->whereBetween('startdate',
array($request->from_date, $request->to_date))
->get();
}
else {
$data = DB::table('holidays')->orderBy('startdate', 'desc')
->get();
}
return response($data);
}
你可以像这样使用它
$holiday = Holiday::where('from_date', '>=', $date)->where('to_date', '<=', $date)->get();
Your fetch_data
method in custom_script.js should be something like that as your previous script您在custom_script.js 中的
fetch_data
方法应该与您之前的脚本类似
function fetch_data(from_date = '', to_date = '') {
$.ajax({
url:"{{ route('holiday.fetch_data')}}",
method:"POST",
data:{
from_date:from_date, to_date:to_date, _token:_token
},
dataType:"json",
success:function(data) {
var output = '';
$('#total_records').text(data.length);
for(var count = 0; count < data.length; count++) {
output += '<tr>';
output += '<td>' + data[count].id + '</td>';
output += '<td>' + data[count].firstname + '</td>';
output += '<td>' + data[count].lastname + '</td>';
output += '<td>' + data[count].startdate + '</td>';
output += '<td>' + data[count].enddate + '</td></tr>';
}
$('tbody').html(output);
}
})
}
you used my script here,which i used for demonstration purpose.This is not workable code.You must need to make ajax
request to the server
to get some data as a response
.您在这里使用了我的脚本,我将其用于演示目的。这不是可行的代码。您必须向
server
发出ajax
请求才能获取一些数据作为response
。
