jpgraph and mysql passing array

Hello,



I hope you can help me. The Jpgraph forum seems to be pretty
uneventful with participation.

I am trying to pass arrays through the image tag to populate my
variables for my graph.

I keep getting an error that there is no input. Do you have any suggestions=
?

I would greatly appreciate it! I have been trying to figure this out
for several hours.



Below is my code:



I need some help with finding a solution. For some reason my graph is
not showing up when it evident that my arrays are being passed.



When I use:



echo "TEST DATA PRINT";

print_r($datay,false);



-------------------



I keep getting the error:

Empty input data array specified for plot.



-----------------------



My php script is as follows:

-----------------------



"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">










ini_set('display_errors', 1);

error_reporting(E_ALL);



$term=3D$_POST['term'];

$term2=3D$_POST['term2'];

$term3=3D$_POST['term3'];



//include ('err_reporting.php');

require ('PHP_Scripts/config.php');

require_once ('jpgraph/jpgraph.php');

require_once ('jpgraph/jpgraph_line.php');



   $sql =3D ("SELECT * FROM evdobanding WHERE Market like '%$term' and
Cell_Sect =3D '$term2' and Date =3D '$term3' ORDER BY distance asc");

   $result =3D mysql_query($sql);



   while($row =3D mysql_fetch_array($result))

   {

   $datay[] =3D $row["MBusage"];

   $datax[] =3D $row["Distance"];

   }

=A0 echo "TEST DATA PRINT";

=A0 print_r($datay,false);

?>

If $datay shows as empty, my first step would be to check that your SQL
query doesn't return an empty set.

note the closing PHP tag above, and now

this line here, is not in php, and does not echo the php variables.

Re: jpgraph and mysql passing array

Would you try an experiment?

In this line:
$sql =3D ("SELECT * FROM evdobanding WHERE Market like '%$term' and=
Cell_Sect =3D '$term2' and Date =3D '$term3' ORDER BY distance asc");

Change to:
$sql =3D "SELECT * FROM evdobanding WHERE Market like '%".$term."' and=
Cell_Sect =3D '".$term2."' and Date =3D '".$term3."' ORDER BY distance=
asc";

That is, remove the parenthesis and concatenate the variables into the=
string.

Thanks for for the suggestion but this didn't seem to work. I beleive
it is a header conflict based on what I have researched.
I just can't seem to find a solution.

The code in the PHP block:

echo "TEST DATA PRINT";
print_r($datay,false);

is passing all the values from the sql query because I can see them on
the page with the jpgraph error.

For example:

TEST DATA PRINTArray ( [0] => 665 [1] => 7093 [2] => 30000 [3] =>
45816 [4] => 70848 [5] => 41365 [6] => 35676 [7] => 22434 [8] => 5450
[9] => 29131 [10] => 35244 [11] => 48614 [12] => 51748 [13] => 55497
[14] => 79042 [15] => 732 [16] => 1375 [17] => 1094 [18] => 897 [19]
=> 1122 [20] => 3059 [21] => 5350 [22] => 5080 [23] => 3082 [24] =>
2737 [25] => 326 [26] => 1334 [27] => 736 [28] => 469 [29] => 127 [30]
=> 105 [31] => 111 [32] => 197 [33] => 208 [34] => 950 [35] => 9 [36]
=> 9 [37] => 19 [38] => 8 [39] => 17 [40] => 90 [41] => 1917 [42] =>
1289 [43] => 2051 [44] => 1534 [45] => 1 [46] => 2 [47] => 4 [48] => 4
[49] => 7 [50] => 8 [51] => 9 [52] => 18 [53] => 22 [54] => 5 [55] =>
3 [56] => 1 [57] => 1 [58] => 2 )

JpGraph ERROR 25121



From the research I have done so far using Jpgraph I have found this
link to a similar issue:

http://ubuntuincident.wordpress.com/tag/jpgraph/

but I am unable to get my arrays from the sql query to populate the graph.

Thank you in advance,

Chris
