# Pi-Star Information Scraper & Display
|
||||
|
||||
This lazily named pair of scripts will allow you to display DStar or DMR
|
||||
information using PHP.
|
||||
|
||||
## About
|
||||
|
||||
I got the bright idea that I wanted to display my hotspot status information on
|
||||
my QRZ page. Like most things ham; it doesn't look nice. It's a no frills php
|
||||
page that just drops text in a table with basic formatting. I go about as far
|
||||
as using viewport information to make it look better in various framesizes. It
|
||||
was designed to be placed in an iFrame.
|
||||
|
||||
This script has not seen any updates in months due to working how I wanted it
|
||||
to and not causing issues. In fact I forgot it was working until going to make
|
||||
this repository.
|
||||
|
||||
## Example
|
||||
|
||||
I am going to try to ebed an iFrame in the readme.
|
||||
|
||||
<iframe frameborder="0" height="300" scrolling="no" src="https://qth.nq4t.com/hotspots.php" width="320"></iframe>
|
||||
|
||||
If this doesn't work you can visit:
|
||||
|
||||
https://qth.nq4t.com/hotspots.php
|
||||
|
||||
The direct version will be "full-screen". Just remember this was designed for
|
||||
iframes.
|
||||
|
||||
## Usage/Setup
|
||||
|
||||
To use this you must meet the following conditions:
|
||||
|
||||
```
|
||||
You must have a web-server running PHP
|
||||
Your web-server must be able to access your hotspot dashboard
|
||||
```
|
||||
|
||||
It may be possible to run this with everything on a different network without
|
||||
having to expose your hotspots. A VPN could provide a way for your remote www
|
||||
server to access dashboards. Running the script remotely and having your web-
|
||||
server get results via SSH is another possiblity. I'll script this when I get a
|
||||
chance.
|
||||
|
||||
You will need to load hotspot.sh and edit the hostname information. You will
|
||||
also need to configure if you're using D-Star or DMR. Other modes may work with
|
||||
the DMR setting, like YSF. DMR scrapes the bm_links.php while Dstar scrapes
|
||||
repeaterinfo.php's "Linked To" box.
|
||||
|
||||
Place hotspots.php in a document root and edit it to match where you put your
|
||||
shell script. Simply loading hotspots.php is all you need to do.
|
||||
|
||||
## Testing/Troubleshooting
|
||||
|
||||
You can easily test both parts of this script to check that the output is
|
||||
sane and for debugging purposes. When you run the bash script by itself, you
|
||||
will get output like this:
|
||||
|
||||
```
|
||||
dewdude@ovh:/media/html/qth-nq4t$ ./hotspot13alpha.sh
|
||||
<tr><td style="vertical-align: top; font-family: Verdana; font-weight: bold; text-align: right;"><small>BM TG:</small></td>
|
||||
<td style="vertical-align: top;"><small style="font-style: italic;">#3151 - #8802 - #31514 - #98003 </small><br></td></tr>
|
||||
```
|
||||
|
||||
The bash script literally just generates HTML code; but it's still clear that
|
||||
it's outputting talkgroup numbers. The PHP file, hotspots.php, basically
|
||||
generates an entire webpage.
|
||||
|
||||
```
|
||||
dewdude@ovh:/media/html/qth-nq4t$ php hotspots.php

```
|
||||
|
||||
As you can see between `<tbody>` and `</tbody>` is our script output.
|
||||
|
||||
If the bash script doesn't get data or can't connect, it will just hang for a
|
||||
while and output nothing. If PHP can't execute the script, it will generate an
|
||||
error in the output.
