PHPlot / Discussion / Help and Discussion: can't get data from another php file

muppet77 - 2010-12-09

i have 12 different rainfall totals stored as variables in 12 different files
- 1 for each month.

the numbers display on the graph, but the wrong ones.

the top part of my code is

<?php

include 'jan.php';

include 'feb.php';

include 'mar.php';

include 'apr.php';

include 'may.php';

include 'jun.php';

include 'jul.php';

include 'aug.php';

include 'sep.php';

include 'oct.php';

include 'nov.php';

include 'dec.php';

PHPlot Example: Two plots on one image

require ($_SERVER . '/phplot.php');

$data2 = array( # Data array for rain plot:

array('JAN', $out_tot_rainjan), array('FEB', $out_tot_rainfeb), array('MAR',
$out_tot_rainmar),

array('APR', $out_tot_rainapr), array('MAY', $out_tot_rainmay), array('JUN',
$out_tot_rainjun),

array('JUL', $out_tot_rainjul), array('AUG', $out_tot_rainaug), array('SEP',
$out_tot_rainsep),

array('OCT', $out_tot_rainoct), array('NOV', $out_tot_rainnov), array('DEC',
$out_tot_raindec),

);

the files can be found at www.maidenerleghweather.com/jan.php etc

the graph is /graph2.php

any idea what's going on?

PS: I ONLY EXPECT JAN, FEB, MAR AND AUG TO SHOW.

JAN is accurate, the rest are out.

eg AUG should be 113 ?????

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

muppet77 - 2010-12-09

... and when i add

print $out_tot_rainaug;

to the august file it prints 113.

so that part is correct???

Hi, we are going to need to see some more information, such as what is in
those data files. (Your link doesn't work, as "jan.php" is probably running on
your server with PHP so we can't see what is in it.) Also what is your data
type (SetDataType), plot type, etc? If you could include the whole script (if
short enough) that would be even better. Or, if you are debugging with print,
try checking the data array you are giving SetDataValues, for example
print_r($data2) instead of producing the graph.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

aug.php cuts values from a file called all.txt

(in fact all the month files do - jan, feb etc)

when i add print $out_tot_rainaug;

to the august file it prints 113.

the aug file is

You are missing a number of quote marks around constant strings in graph2.php,
like 'plotin', 'blue', 'plotright'. Can I assume those happened when you
posted this, and the actual script is correct? (That is, you are have error
checking on and have made sure you aren't getting PHP syntax errors or
undefined variable/constants warnings.)

Also, can you tell me what PHPlot version you are using?

I took your code, fixed the quotes, and substituted constant values for the 12
out_tot_rain* (first 3 values, aug value, and the rest are empty strings), and
I get the same picture as you, except the aug number is what I put in. So that
points again to your data values. What I would try at this point is insert
these 3 lines just before SetDataValues($data2):

header("Content-type: text/plain"); print_r($data2); exit();

Now go to the script's URL and you should see a listing of your data array
exactly as PHPlot will see it. Do the values and format look correct?

no - it shows Aug to be 15.4 not 113?

bit of a breakthrough.

i think that the variables from each month file are confusing each other as
they have identical names.

//include 'jan.php';

//include 'feb.php';

//include 'mar.php';

//include 'apr.php';

//include 'may.php';

//include 'jun.php';

//include 'jul.php';

include 'aug.php';

//include 'sep.php';

//include 'oct.php';

//include 'nov.php';

//include 'dec.php';

when i just select the aug file it returns a bar in the graph as 113 - which
is correct.

i will adjust variable names.

ok - no idea what's going on now.

all variables have different names.

the latest effort is at http://www.maidenerleghweather.com/graph.php

the max and min seem to be ok. the averages are wrong as are the rainfall.
remmeber as a cgeck aug should be 113 rain.

i have the graph.php code as

worked it out - still duplicate variable names in different files causing
error.

will sort it tonight.

thanks for looking and helping - hope this helps someone else.

be thorough!!!!

Sorry for not replying before now - my ISP seems to have taken the weekend off
(unable to reach sourceforge.net directly, but the forum emails were getting
through because they don't go direct to me from sourceforge.net... So I could
see what you were posting but could not reply). I'm glad you found the
problem. I was going to suggest looking more carefully at the code, or even
trying to find a better way, as having 12 almost-the-same copies of scripts
and variable names seems to be asking for trouble.
