我想将一个值从控制器传递到公用文件夹中的.php文件。这是我的控制器部分
<?php namespace App'Http'Controllers;
use App'Http'Requests;
use App'Http'Controllers'Controller;
use Illuminate'Http'Request;
use Illuminate'Support'Facades'DB;
class DashboardController extends Controller {
public function barChart(){
$barChart= DB::table('clients')
->select('clients.ClientName','clients.Price')
->get();
//want to pass this $barChart variable
}
php文件的位置是
/dist/chart/clients.php
我想在clients.php文件中有这个$barChart变量，并执行进一步的操作。
更新1:这是视图部分
<div class="panel-body" id="barChart">
</div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$.ajax({
//url: "{{URL::asset('/dist/chart/clients.txt')}}", //this works, I saved the json_encode($bar) at client.txt file
data: [{{$bar}}], //this does not work
dataType:"JSON",
success: function(result){
google.charts.load('current',{
'packages':['corechart']
});
google.charts.setOnLoadCallback(function(){
drawChart(result);
});
}
});
function drawChart(result) {server.
var data = new google.visualization.DataTable();
data.addColumn('string' , 'ClientName');
data.addColumn('number', 'Price');
var dataArray=[];
$.each(result, function(i, obj){
dataArray.push([obj.ClientName, parseInt(obj.Price)]);
});
data.addRows(dataArray);
var barChart_options = {
title: 'hoise??',
is3D: 'true',
width: 400,
height: 300
};
var barChart = new google.visualization.BarChart(document.getElementById('barChart'));
barChart.draw(data, barChart_options);
}
});
</script>
更新2
控制器更新
<?php namespace App'Http'Controllers;
use App'Http'Requests;
use App'Http'Controllers'Controller;
use Carbon'Carbon;
use Illuminate'Http'Request;
use Illuminate'Support'Facades'DB;
class DashboardController extends Controller {
public function index()
{
try{
$val=DB::connection()->getDatabaseName();
if(DB::connection()->getDatabaseName()) {
$barChart= DB::table('clients')
->select('clients.ClientName','clients.Price')
->get();
$bar = json_encode($barChart);
return view('home')
->with('bar', $bar);
}else{
$er="/connection status: database error";
return view('errors/503')->with('error',$er);
}
}catch ('Exception $e){
$er="/connection status: database error";
return view('errors/503')->with('error',$er);
}
}
public function barChart(){
$barChart= DB::table('clients')
->select('clients.ClientName','clients.Price')
->get();
echo json_encode($barChart);
}
public function create()
{
//
}
public function store()
{
//
}
public function show($id)
{
//
}
public function edit($id)
{
//
}
public function update($id)
{
//
}
public function destroy($id)
{
//
}
}
将clients.php添加到resources/views目录并将其命名为clients.blade.php，它的工作原理相同，但为您提供了一个不错的模板引擎。
在controller/barChart方法中执行此操作。
$barChart= DB::table('clients')
->select('clients.ClientName','clients.Price')
->get();
return view('clients', compact('barChart'));
在视图文件resources/views/clients.blade.php中，您现在可以访问$barChart变量。
你可以这样在你的视图中使用它：
{{ json_encode($barChart) }}
或者如果你没有使用刀片，那么
<?= json_encode($barChart) ?>
希望这能有所帮助。
将您的clients.php放入res enter code here sources/views目录，并将其命名为clients.lade.php
像一样更改控制器
<?php
namespace App'Http'Controllers;
use App'Http'Requests;
use App'Http'Controllers'Controller;
use Illuminate'Http'Request;
use Illuminate'Support'Facades'DB;
class DashboardController extends Controller {
public function barChart(){
$barChart=DB::table('clients')
->select('clients.ClientName','clients.Price')- >get();
return view('clients')->with('barChart' => $barChart);
}
?>
我终于想出了解决方案。我不能将变量传递到公用文件夹，在ajax中提供ulr也是一个问题。在这种情况下，创建数据表是令人讨厌的，然后传递它。控制器部分将是
public function index()
{
try{
$val=DB::connection()->getDatabaseName();
if(DB::connection()->getDatabaseName()) {
$barChart= DB::table('clients')
->select('clients.ClientName','clients.Price')
->get();
$rows = array();
//flag is not needed
$flag = true;
$table = array();
$table['cols'] = array(
array('label' => 'Weekly Task', 'type' => 'string'),
array('label' => 'Percentage', 'type' => 'number')
);
$rows = array();
foreach($barChart as $r) {
$temp = array();
$temp[] = array('v' => (String)$r->ClientName);
$temp[] = array('v' =>(int)$r->Price);
$rows[] = array('c' => $temp);
}
$table['rows'] = $rows;
$bar = json_encode($table);
return view('home')
->with('bar', $bar);
}else{
}
}catch ('Exception $e){
}
}
视图部分将是
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
function drawChart() {
// Create our data table out of JSON data loaded from server.
var data = new google.visualization.DataTable(<?=$bar?>);
var options = {
title: 'My Chart',
is3D: 'true',
width: 400,
height: 300
};
// Instantiate and draw our chart, passing in some options.
// Do not forget to check your div ID
var chart = new google.visualization.BarChart(document.getElementById('barChart'));
chart.draw(data, options);
}
</script>
