PHP - Charts Needed
Hello,
I'm working on a project that takes a CSV (poorly formated unfortunately) and turns it in charts. What should I use? Maani XML/PHP, Pcharts, ...? There are so many possibilities, I'm lost. What do you guys recommend? thanks (if maani is any good, how do I convert something like Array ( => Array ( => Array ( => FORMULE ENTREE+PLAT [1] => 24 ) [1] => Array ( => FORMULE PLAT+DESSERT [1] => 34 ) ) [1] => Array ( => Array ( => ASSIETTE DE FRITES [1] => 2 ) [1] => Array ( => ASSIETTE MIXTE [1] => 1 ) [2] => Array ( => SALADE AUVERGNATE [1] => 8 ) [3] => Array ( => SALADE CHARENTAISE [1] => 17 ) [4] => Array ( => SALADE DU BURON [1] => 10 ) [5] => Array ( => SALADE FERMIERE [1] => 3 ) ) into a XML file? Similar TutorialsMy wife is a Type 1 diabetic and I am trying to put a site together where she can record her blood/glucose readings and analyse the readings.
I am trying to use Google Charts to create a line graph so that she can see if their is a trend during the day when her blood sugar levels peak and trough. But my coding isn't providing any results.
Can anyone see what I am doing wrong?
<?php
$level=DB::getInstance()->query("SELECT * FROM tabbyhealth WHERE reading!=0");
foreach ($level->results() as $levelresults)
$glucose = $levelresults->reading;
$timestamp = date('d M Y h.i A',strtotime($levelresults->timestamp) +18000);
?>

data.addColumn('number', 'Blood Glucose Reading');

I have even tried replacing
data.addRows([

]);
with
data.addRows([
[0, 0, 0], [1, 10, 5], [2, 23, 15],
[3, 17, 9], [4, 18, 10], [5, 9, 5],
[6, 11, 3], [7, 27, 19], [8, 33, 25]
]);
to see if it is just a problem with reading from my database, but I am still getting nothing - by nothing I mean that no chart is appearing.
This topic has been moved to Other Libraries and Frameworks. http://www.phpfreaks.com/forums/index.php?topic=352327.0 Good morning,
I am doing a small project including google charts API but I am having trouble getting my results into the json format that is required.
Google's documentation states the json format should be:
{
"cols": [
{"id":"","label":"Topping","pattern":"","type":"string"},
{"id":"","label":"Slices","pattern":"","type":"number"}
],
"rows": [
{"c":[{"v":"Mushrooms","f":null},{"v":3,"f":null}]},
{"c":[{"v":"Onions","f":null},{"v":1,"f":null}]},
{"c":[{"v":"Olives","f":null},{"v":1,"f":null}]},
{"c":[{"v":"Zucchini","f":null},{"v":1,"f":null}]},
{"c":[{"v":"Pepperoni","f":null},{"v":2,"f":null}]}
]
}
the query works perfectly fine thats not the problem but getting it into the above format is proving hard than I expected. The below is what I am trying to do to populate the json data in the correct format.
function graphdata()
{
$array['cols'][] = array('type' => 'string');
$array['cols'][] = array('type' => 'string');
$array['cols'][] = array('type' => 'string');
$result = sqlsrv_query($conn, $query);
while($row = sqlsrv_fetch_object($result)){
$array['rows'][] = array('c' => array( array('v'=>'$row->DateCreated->format('d-m-Y')'), array('v'=>$row->UnitPrice)) );
}
return $array;
}
print json_encode(graphdata());
I am using MSSQL and not the normal mysql hence the above code, i am a starter when it comes to php so I may be doing something basic totally wrong but I cannot seem to get it to work.

However, I got stuck with inserting data from pHp using json_encode. It works for the most simple array, with using 2 values. When using array of arrays, it does not work. I believe it could be a syntax errors with all those brackets but I could not figure it out. Thanks for any ideas!

Hi, Ihave the below array output from a DB query. I need to convert into the bottom array for Google CHarts. Any ideas? $myarray = array( 0 => array( 'year' => 2009, 'month' => "January", 'month_sales' => 524, 'year_totalsales' => 3610 ), 1 => array ( 'year' => 2009, 'month' => 'February', 'month_sales' => 521, 'year_totalsales' => 3610 ), 2 => array ( 'year' => 2009, 'month' => 'March', 'month_sales' => 501, 'year_totalsales' => 3610 ), 3 => array ( 'year' => 2009, 'month' => 'April', 'month_sales' => 601, 'year_totalsales' => 3610 ), 4 => array ( 'year' => 2009, 'month' => 'May', 'month_sales' => 710, 'year_totalsales' => 3610 ), 5 => array ( 'year' => 2009, 'month' => 'June', 'month_sales' => 801, 'year_totalsales' => 3610 ), 6 => array ( 'year' => 2009, 'month' => 'July', 'month_sales' => 991, 'year_totalsales' => 3610 ), 7 => array ( 'year' => 2009, 'month' => 'August', 'month_sales' => 301, 'year_totalsales' => 3610 ), 8 => array ( 'year' => 2009, 'month' => 'September', 'month_sales' => 250, 'year_totalsales' => 3610 ), 9 => array ( 'year' => 2009, 'month' => 'October', 'month_sales' => 322, 'year_totalsales' => 3610 ), 10 => array ( 'year' => 2009, 'month' => 'November', 'month_sales' => 621, 'year_totalsales' => 3610 ), 11 => array ( 'year' => 2009, 'month' => 'December', 'month_sales' => 691, 'year_totalsales' => 3610 ), 12 => array ( 'year' => 2010, 'month' => "January", 'month_sales' => 789, 'year_totalsales' => 1610 ), 13 => array ( 'year' => 2010, 'month' => "February", 'month_sales' => 1409, 'year_totalsales' => 1610 ), 14 => array ( 'year' => 2010, 'month' => "March", 'month_sales' => 550, 'year_totalsales' => 1610 ) ); raw_data=[['January',524,0],['February',521,0],['March',501,0],['April',601,0],['May',710,0],['June',801,0], ['July',991,0],['August',301,0],['September',250,0],['October',322,0],['November',621,0],['December',691,0],['January',789,0],['February',1409,0],['March',550,0],]; raw_data= [ [ month1 , year1 sales figure(zero if no figure), year2 sales figure(zero if no figure).....], [ month1 , year1 sales figure(zero if no figure), year2 sales figure(zero if no figure).....]......]; Thanks all Hi
I am trying to create a google chart from data in query.php and using the google api to load it. Everything works until I want to change the MetalSourceID from a drop select box.
PHP CODE FOR DROP DOWN BOX:
<form>
<select name="users" onchange="showUser(this.value);drawChart();">
<option value=""> Select a Metal: </option>
<?php
$query = "SELECT TOP(31) tblMetalPrice.MetalSourceID, tblMetalSource.MetalSourceName from tblMetalPrice INNER JOIN tblMetalSource ON tblMetalPrice.MetalSourceID=tblMetalSource.MetalSourceID ORDER BY tblMetalPrice.DateCreated DESC ";
$result = sqlsrv_query( $conn, $query);
while( $row = sqlsrv_fetch_object ($result)) {
echo "<option value='".$row->MetalSourceID ."'>". $row->MetalSourceName ."</option>";
}
sqlsrv_close( $conn);
?>
</select>
</form>
This works fine and generates all the correct values. One part of this changes contents of a table which works fine. But I also echo the MetalSourceID into the javascript for the google api, JS script below:
<script type="text/javascript">
google.load('visualization', '1', {'packages':['corechart']});
google.setOnLoadCallback(drawChart);
function drawChart() {
var jsonData = $.ajax({
url: "query.php",
dataType:"json",
async: false,
data: { 'MetalSourceID' : <?php $q = intval($_GET['q']); echo $q; ?> }
}).responseText;
var data = new google.visualization.DataTable(jsonData);
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data);
}
</script>
This then runs the query.php script and returns the google line chart, a copy of the query.php script is below:
i've to populate google charts with dynamic data. the data looks llike. +----+-------+---------+-------+-----------+---------+------+ | id | name | physics | maths | chemistry | biology | sst | +----+-------+---------+-------+-----------+---------+------+ | 1 | Name1 | 10 | 25 | 35 | 42 | 62 | | 2 | Name2 | 80 | 45 | 45 | 45 | 25 | | 3 | Name3 | 63 | 25 | 63 | 36 | 36 | | 4 | Name4 | 82 | 36 | 75 | 48 | 42 | | 5 | Name5 | 45 | 45 | 78 | 25 | 24 | | 6 | Name6 | 36 | 36 | 15 | 75 | 36 | | 7 | Name7 | 99 | 45 | 24 | 24 | 45 | | 8 | Name8 | 45 | 85 | 85 | 85 | 96 | +----+-------+---------+-------+-----------+---------+------+ i have to create google charts based on this such that # namewise - such that when i select a name it displays all subject marks of that particular name in a column chart #markswise - when i select a subject, it displays all the names with marks in that particular subject. conisdiering that data may be added and i've to accumulate that also, for namewise i did

it diplays a blank page. however when i play with singular values i.e one subject at a time it displays fine Edited March 19, 2019 by zetastreakHello everybody,
I am honestly quite a newb when it comes to mod_rewrite.
We run a small social media page with different areas and I would like to change the URLs to something more clean and professional.
User profiles look like this:
http://www.sky-mp3.com/index.php?action=cm&siteid=59&wahl=artists&tat=details&keyid=477siteid 59 is the artists list and the keyid at the end is the ID of the artist but should be like: http://www.sky-mp3.com/mischuraor in worse case like: http://www.sky-mp3.com/user/mischuraCMS pages look like this: http://www.sky-mp3.com/index.php?siteid=106but should be like: http://www.sky-mp3.com/charts(page name instead of siteid) What I know so far: - I have to add something to the .htaccess file - I need to change something in the code (but I don`t know where) Im good he? What would be the first step on the path to clean URLs for me? I found alot of infos here and there but found nothing yet for this specific case. Kind regards from and thx in advance from Cologne I've been surfing the net recently for php cms system that I can implement into my clients websites, I've come across a really cool cms system pagelime. The cool thing about pagelime is that you can assign a css class to any div in the html document and pagelime can remotely read this html document and make that css div editable. then pagelime can save or generate the newly edited page. So... my question is how is this done? do they parse the html document via ftp into a php string then load it into a editor where the code is updated via ajax then remotely written back. Is there a industry word for this type of system? that I could use to find tuts on this topic? If someone is willing to point me in the right direction for more info then I will gladly share my finished cms system Thanks Danny Hi I am new here and I am not a PHP specialist. I run a website (www.theowl.com) and last week I upgraded from PHP 4.X to 5.x on the Namesco server. Everything worked except one thing.... I commissioned an EDI link to DHL, and this was setup using PHP FTP. This system works automatically plus I have a manual link to trigger orders. Since upgrading PHP the automatic process has stopped but the manual process still works fine. Would anybody be able to help. I have attached what I think is the correct file. I am happy to pay for peoples time. i have a piece of code which subtracts credits every time a button is clicked. the original code works fine. I have since added a bonus_credit column, where i want it to function like this. if buy_credit = 0 and bonus_credit>0 then subtract from the bonus credit, but still do everything else its supposed to do.. here is the original code i had $selRes=mysql_query("SELECT buy_credit from user where id='".$hb_id."' and buy_credit>0"); if(mysql_affected_rows()>0) { $b_comm=0; $bc_updqry=mysql_query("UPDATE user set buy_credit=buy_credit-1 where id='".$hb_id."'"); $updqry=mysql_query("UPDATE cars set b_fee_paid_status='1' where id='".$aid."'"); } here is my modified code, but it doesn't seem to subtract from buy_credit if buy_credit is >0.. it should only kick in the bonus_credit usage if buy_credit is 0 $selRes=mysql_query("SELECT buy_credit,bonus_credit from user where id='".$hb_id."' and buy_credit>0 OR bonus_credit>0"); if(mysql_affected_rows()>0) { $b_comm=0; if($selRes['buy_credit']!=0) { $bc_updqry=mysql_query("UPDATE user set buy_credit=buy_credit-1 where id='".$hb_id."'"); } else { $bc_updqry=mysql_query("UPDATE user set bonus_credit=bonus_credit-1 where id='".$hb_id."'"); } $updqry=mysql_query("UPDATE cars set b_fee_paid_status='1' where id='".$aid."'"); } your help is appreciated.

Hello: I have a small chunck of code that dosplays data depending on which PlayerID is selected. Like so: Code: [Select] <?php $myvar = $_REQUEST['PlayerID']; ?> ... <?php if ( $myvar == "1" ) { echo "Your name is Tina"; } elseif ( $myvar == "2" ) { echo "Your name is Sue"; } else { echo "Your name is Jill"; } ?> This works fine - no errors - but I am use to ASP and using an "End If" after "Else" ... Is this not needed in PHP? Thanks. Here's my code snippet. Code: [Select] if(preg_match("/^[ a-zA-Z1-42]+/", $_POST['name'])){ $name=$_POST['name']; $namer=$name; $result = mysql_query("select `resource` from resources where `resource_id` =" .$namer. "ORDER BY `resource_id` ASC "); echo "<br/>The following nations have " .$namer. " as a resource\n"; //-query the database table $sql="SELECT id, nation_id, ruler, resource1, resource2 FROM TS1 WHERE resource1 LIKE '%" . $name . "%' OR resource2 LIKE '%" . $name ."%'"; //-run the query against the mysql query function $result=mysql_query($sql); //-create while loop and loop through result set while($row=mysql_fetch_array($result)){ $ID=$row['id']; $Ruler=$row['ruler']; //-display the result of the array echo "<ul>\n"; echo "<li>" . "<a href=\"searcher.php?id=$ID\">" .$Ruler. "</a></li>\n"; echo "</ul>"; } } else{ echo "<p>Please enter a search query</p>"; } } } Basically I have a number that's posted from a form field from another page to this page. It displays correctly on the results page but what i'm trying to do now is get that number to change based on the query at the top '' $result = mysql_query("select `resource` from resources where `resource_id` =" .$namer. "ORDER BY `resource_id` ASC "); " So if the number 3 (which is in the `resource_id` column) was posted it will display a result (which is in the `resource` column). But it just seems that the query isn't going through and it continues to display the 3 which was originally posted instead of changing 3 to a number in the database. I was thinking of performing a while loop so it just just displays the result of the query.. something like this: Code: [Select] $name=$_POST['name']; $namer=$name; $result = mysql_query("select `resource` from resources where `resource_id` =" .$namer. "ORDER BY `resource_id` ASC "); while($row = mysql_fetch_array($result)) { echo "<br/>The following nations have " . $row['resource'] . " as a resource\n"; }But that seems to have more problems as it doesn't display anything at all, not even the original number I had. I don't think it's a big problem.. Maybe something i've just overlooked?
