Server generated SQL

[richard_newberry]

I am trying to get this to work.

http://desford-weather.co.uk/images/graphHum.php

I have made sure cumulus.realtime exist and it does.

Not quite sure why this isnt working. Anyone have any ideas?

Thank you

P.S going to throw it out the window soon.

Is there any reason to place php file in folder " images " ?

[water01]

I assume that cumulus.realtime is the MySQL table that contains your realtime data?

What that is saying is that it cannot access it, despite you saying the table exists. Now if you are using the standard CumulusMX SQL have you set up that name (realtime) in the name box in the settings as the standard name if you used ImportCumulusFile.php is Realtime with a capital R.

Plus the actual code in graphHum.php

Code: Select all

$query = "SELECT unix_timestamp(LogDateTime) AS time, $cols[attachment=0]jgraph problem.png[/attachment][attachment=0]jgraph problem.png[/attachment]
        FROM Realtime
        WHERE LogDateTime >= now() - INTERVAL " .$GRAPH['hours']. " HOUR
        ORDER BY time";

needs to reflect the naming of the table.

So I suspect that you have either a fault in your graph.settings file or the include file that sets the parameters to access your MySQL database.

On looking at the gauges on your site none of the images appear so that is consistent with incorrect settings.

Edit
Just checked a couple of other things. If it is working correctly you should be able to see the picture generated by using this URL http://desford-weather.co.uk/images/hum.png but in your case you appear to also have a jpgraph problem.

I don't know how to sort it out but would like to know what is causing it though.

graphsettings.php im /var/www/images see below.



$GRAPH = array();
############################################################################
# CONFIGURATION INFORMATION
############################################################################
$GRAPH['version'] = '1.7';
$GRAPH['width'] = 600;
$GRAPH['height'] = 300;
$GRAPH['jpgraphloc'] = '/var/www/jpgraph/'; // Path to jpgraph, or put it in your PHP path
// NOTE: This is the *server* operating system path to the file, so unless you have added
// the web folder to your PHP path, it will be something like "/home/<userid>/www/jpgraph/"
$GRAPH['cachetime'] = 10; // number of minutes to cache images
$GRAPH['hours'] = 24; // number of hours to graph
$GRAPH['uom'] = array('temp'=>'C', 'rain'=>'mm', 'wind'=>'mph', 'baro'=>'hPa', 'cloudbase'=>'feet');
$GRAPH['rosePoints'] = 16; // 8 or 16
$GRAPH['roseSize'] = 400;
// Localised Compass point array
$GRAPH['compass'] = array('N','NNE','NE','ENE','E','ESE','SE','SSE','S','SSW','SW','WSW','W','WNW','NW','NNW');

in /var/www/jpgraph/jpg-conf.inc.php see below

define('CACHE_DIR','/var/www/jpgraph/csimcache/');
define('TTF_DIR','/var/www/jpgraph/fonts/');
define('MBTTF_DIR','/var/www/jpgraph/fonts/');

//-------------------------------------------------------------------------

define('CSIMCACHE_DIR','csimcache/');

all have chmod 775 permissions?

in jpgraph/fonts

I Have arial.ttf and verdana.ttf all chmod 775

Any ideas people??

[richard_newberry]

I have no cumulus.realtime problem no more just jpgraph problem now.

Tried restoring jpgraph folder from a backup and still the same problem?

[laulau]

Do you have DejeVuSans.ttf installed in fonts ?

Capture.PNG

[water01]

I very much doubt that JpGraph is installed at /var/www/.

It should be in your server area where your web site is installed so it is going to be more like

Code: Select all

$GRAPH['jpgraphloc']     = '../jpgraph/'; // Path to jpgraph, or put it in your PHP path

[richard_newberry]

Its in /var/www where jpgraph is located where jpgraph is located.

[water01]

But the jpgraphloc is a relative location not a complete location so if it is in a directory within your website the correct location is ../jpgraph.

The only other possibility is that the font doesn't exist within the fonts directory within the jpgraph directory.

[richard_newberry]

root@debian:/var/www/jpgraph/fonts# ls
arial.ttf DejaVuSans-Bold.ttf DejaVuSans.ttf FF_FONT0.gdf FF_FONT1.gdf FF_FONT2.gdf lcdmono2ultra-webfont.svg LICENSE.TXT

PHP Notice: date_default_timezone_set(): Timezone ID '+0:00' is invalid in /var/www/images/graphSettings.php on line 45, referer: http://desford-weather.co.uk/images/

if set to Europe/London I get a Error TZ Statement.

Done that no change.

It's something to do with php open_basedir not allowing jpgraph to access the fonts.

in /etc/php/7.3/apache2/php.ini I have ;open_basedir =

[richard_newberry]

Problem I have got now is as following:-

Error TZ Statement if I don't set timezone to +00:00 then I get the following error message.
PHP Notice: date_default_timezone_set(): Timezone ID '+00:00' is invalid in /var/www/images/graphSettings.php on line 45, referer: http://desford-weather.co.uk/gauges-ss.htm

Also on jpgraph faq website I have created the following file and tested to see if php can find the fonts file or not.

https://jpgraph.net/doc/faq.php#F3-6

I have called this checkfonts.php as you can see http://desford-weather.co.uk/checkfonts.php php finds the font folder and says the following message.
PASS: Successfully read font file "/var/www/jpgraph/fonts/DejaVuSans.ttf". as I am having an error with jpgraph error 25092

So this is down to a problem with jpgraph which I have reported the problem with jpgraph or it's the SQL files im /images folder which Mark have created. (not blaming mark btw).

I am running wordpress due to business website and latest wordpress version requires php7.4. jpgraph 4.3.1 supports php7.4

So as a IT Technician I know a little about php but not much more hardware and software problem solving guy not really a coding type of person.

So any coding specialist people reading this can you give me any ideas how to sort this out please.

I am beginning to have greys hairs now. This is an interesting problem now.

It's only pictures but just makes the gauges complete and look nice.

Thanks for any suggestions.

As a matter of interest if you run phpinfo.php (I have attached it just in case) on your server does it show that gd is available as per the picture?

gd.png

Note I have attached phpinfo as phpinfo.txt (Forum does not allow uploads of php files) just rename it as phpinfo.php upload it and run I presume http://desford-weather.co.uk/phpinfo.php

The reason I ask is the php extension gd is required to run jpgraphs.

[richard_newberry]

Thanks for replying mate.

http://desford-weather.co.uk/phpinfo.php click on it and you'll see Gd displaying the following:-

gd
GD Support
enabled
GD headers Version
2.2.5
GD library Version
2.3.0
FreeType Support

JPEG Support

XPM Support

XBM Support

WebP Support

That's a tick to say it's enabled.

[water01]

No problem.

Therefore it is still a path problem as you have tested the permissions, but I must admit it has me puzzled, need to think about it!!
