I am trying to implement ParamQuery an excel like plugin in php.I am trying to fetch the data from a php which generates json output.It is fetching properly but i want to display the datas within the div:grid_array in the specified format.Am not able to do that The fields are all coming blank.
My json output code:data.php
<?php
$conn = mysql_connect('localhost','root','pass');
if(!$conn){
die('Mysql connection error '.mysql_error());
}
$db = mysql_select_db('pop',$conn);
if(!$db){
die('Database selection failed '.mysql_error());
}
$sql = 'SELECT *FROM items';
$result = mysql_query($sql,$conn);
$data = array();
while($row = mysql_fetch_array($result)){
$row_data = array(
'id' => $row['Item_id'],
'Product' => $row['Product'],
'Brand' => $row['Brand'],
'Model' => $row['Model']
);
array_push($data, $row_data);
}
echo json_encode($data);
?>
my html file which should display the data:

Maybe It's too late to answer already, anyway I see that you didn't set up colModel properly... I mean, you forgot to link the columns to the "fields".
i.e.:
{ title: "Product", width: 200, dataType: "string", dataIndx: "Product" }
where dataIndx is the JSON field; "title" is only the caption, but not directly the data binding... and as result what you can see is the row but blank
I have based on paramgrid demo here
You can see de dataIndx fields inside colModel structure...
im trying to print results stored in my database using php and highcharts api.but the graph doesnt show on the screen.not even the axis get displayed.the data is got from a mysql database.i tries using the same code as in the highcharts demo but no luck.heres my code
<?php
require_once ('connection.php');
session_start();
$username = $_SESSION['username'];
$quizes=null;
$score=array();
$i=0;
$result = mysql_query("SELECT * FROM `score` WHERE `username`='$username'") or die(mysql_error);
while($rows=mysql_fetch_array($result)) {
$quizes= $quizes. "'".$rows['quiz']."',";
$score[$i]=$rows['score'];
$i=$i+1;
}
print_r($score);
echo $quizes;

Here js will import data from mysql using data.php file and supply it to our chart
data.php
$con=mysql_connect('localhost','root','');
mysql_select_db("test", $con);
$result=mysql_query('select * from sales order by id');
while($row = mysql_fetch_array($result)) {
echo $row['month'] . "\t" . $row['amount']. "\n";
}
data.php will simply print value on page that we will use for chart.
You can use this method with multiple charts on same page and no more files will required for more then single chart.
It will output like

I think your getting data in string format. convert data to integer like this way,
var mk1=<?php echo $score[1] ?>;
to integer: +mk1 // and check typeof +mk1
Here is the demo http://jsfiddle.net/XF293/
I advice to consider use json_encode() in php and return all values as single array. Then use $.getJSON() to avoid problems with printing values. As a result how your data looks like? I mean in javascript.

I have two files. One is tempTesting.php and another is using flot to graph the data displayed on project.html. But I cannot get the value from the tempTesting.php and display it on project.html.
When I run the project.html it gives me a syntax error on this line:
var dat = <?php echo $return; ?>;
tempTesting.php
<?php
$return="[123456789,22.55],[234567891,22.32]";
$maxtemp=-10;
$mintemp=50;

Try var dat = "<?php echo $return; ?>"; instead.
Without quotes, if $return contains a string, javascript will interpret it as a variable, which is I think not the desired result.
Also, I you didn't set you server configuration to execute PHP in HTML files, this won't work since your file has a '.html' extension. Just rename your file to 'project.php' and it should be OK.
You cannot call PHP functions within a Javascript script. When the page loads, PHP is rendered first, followed by CSS and Javascript. So the line var dat = <?php echo $return;?>; wouldn't run properly.
Instead, you can use an Ajax request. Example here.
EDIT: Understood the question wrong. You cannot use PHP functions within a Javascript function dynamically. However, accessing just an echo command works.
i have to create a single chart showing different series with different type of chart (Ex: one data series with 'areaspline' and one data series with 'column'). I built a db with a lot of data, extracted by sql query into a json file
[
{ "name": "Test", "data": [2.8,2.8,2.8,2.7,2.7,] },
{ "name": "kwc", "data": [10,1,10,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0] }
]
The json file is correct, but if i try to select the series for a chart with the $.each function it doesn't work!

I tryed any kind of option, but anything gone right :(
Any hope to display 1 chart, 2 or more data series and 2 or more type of charts?
Thanks in advance
It looks like your highcharts creation call is within your $.each function. So it will try to create 2 highcharts, but they both will be created in the same div, so you'll only end up with one.
Also, the way you are caculating datalength, it'll be 2. When, it appears, you'd like it to be the length of the actual data (which is different for your different series).
I can't do the getJSON in a jsfiddle, so I'm assuming your PHP code is creating the json object you listed (and it looks like it would). You can lose the each loop alltogether and set your 2 series like this:
series: [{
name: 'Misure',
color: '#4572A7',
type: 'column',
yAxis: 1,
data: json[1].data,
tooltip: {
valueSuffix: ' Kw'
}
}, {
name: 'Temperature',
color: '#89A54E',
type: 'spline',
data: json[0].data,
tooltip: {
valueSuffix: '°C'
}
}]

I am trying to get data from my mysql into Highcharts bar graph. I have the data from mysql that includes a port number and average bytes per port. Here is what I have for my php query and html page. The data (average bytes) shows up on the graph just fine. I can't get the categories (port) data to display.
<?php
$con = mysql_connect("localhost","root","kdkdkdk") or die(mysql_error());
mysql_select_db("silk", $con);
$result = mysql_query("SELECT dstPortNum,avgByte FROM statistic_avgbytesport ORDER BY avgByte DESC LIMIT 10;");
$rows = array();
while($r = mysql_fetch_array($result)) {
$row[0] = $r[0];
$row[1] = $r[1];
array_push($rows,$row);
}
print json_encode($rows, JSON_NUMERIC_CHECK);
#print json_encode($rows[0][0], JSON_NUMERIC_CHECK);
mysql_close($con);
?>
And my html page to display the graph.

You can use something like this:
$.getJSON("averageBytesPerPort.php", function(json) {
var options = {
chart: {
renderTo: 'avgbytes'
},
title: {
text: 'Average Bytes Per Port'
},
pane: {

title: {
text: 'Bytes'
}
},
series: [{
type: 'bar',
name: 'Average Bytes',
data: data
}]
}
chart = new Highcharts.Chart(options);
});
how the hell on earth your data is shown , you have not put the $conn as the second parameter of the
mysql_query();
it should be
$result = mysql_query("SELECT dstPortNum,avgByte FROM statistic_avgbytesport ORDER BY avgByte DESC LIMIT 10;",$conn);
