MySQL and PHP Tutorial

admin — Mon, 16 Apr 2012 14:13:57 +0000

When I am learning something I get pretty discouraged by the books available. They are too long and too damned expensive. I will buy a 400 page book for 50 bucks and read the 30 pages I need. So, I wrote an e-book called MySQL and PHP an Introduction and published it on Amazon (Link here). It is 6.99, about 50 pages and comes with a complete web application. I just today added some real world examples. It demonstrates how to do things like sub queries, in clauses, not in clauses and when they are useful.

mysqlimport – can’t get stat of file

admin — Tue, 22 Nov 2011 14:20:30 +0000

So on my server here I have a process that ftps some data from a SQL server and loads it to MySQL. All was well until I got:
Can’t get stat of ‘/home/username/www/data’ (Errcode: 13)

I tried chmod and chown and running the file as root and everything. No success. I then found a post that said – move the file to /tmp. So I tried it and it worked! Here are my scripts.

Please note – you will have to add a user to mysql that has import permissions!

sql

truncate table equipment_in;

LOAD DATA INFILE ‘/tmp/equipment.csv’
REPLACE
INTO TABLE equipment_in
FIELDS TERMINATED BY ‘,’
OPTIONALLY ENCLOSED BY ‘”‘
LINES TERMINATED BY ‘\r\n’;

getdata

cd /tmp
rm *.csv*
wget ftp://username:password@servername/*.csv
mysql –user=username –password=thepassword databasename < /folder/with/the/sql

SEO and You

So you are thinking you need the services of an SEO (Search Engine Optimization) company. My experience with them so far is less than stellar. They seem to be good at using lots of words and “exciting phrases of the day”. Here are the basics that cover 95% of SEO:

1: Page Titles should be descriptive.
2: Description meta tag should be complete. When you do a google search and see a paragraph under the result, that comes from the description.
3: Keywords meta tag should be complete.
4: Important words in your content should be bold or strong.
5. Use H1, H2 and H3 tags to identify page sections.

Finally, If you are a member of a trade group or organization in your field, link to their pages. Ask if they will link back. If your site has lots of information about “Bees” that is great. If it also links to other pages about “Bees” that is better. If other sites dealing with “Bees” link back to you, that is best.

Lockboxdata.com – secure, online stuff

admin — Thu, 22 Sep 2011 18:45:41 +0000

So a while ago – in fact years ago – I had this idea. I thought, “what happens if something happens to me or my house?” I mean, would my wife know the username and password to my business account? Where the life insurance is? What we need is an online lockbox to save this stuff. So – I wrote Lockboxdata.com. It does all that and more. You can share documents safely and keep all sorts of records. The data is all encrypted and each account has it’s own key.

Anyway – if you want to use it – use the code LBOXWELCOME for a free account.

Geeks and Message Boards

admin — Wed, 14 Sep 2011 15:04:45 +0000

When I go to a message board and ask something like, “how do I limit port 3306 to one computer using iptables?” and you know the answer, please just answer the damned question. I know you have it in your iptables config file. It is probably simple. Don’t point us to a website on iptables (we already found that and said, “WTF?”. Copy the lines in question and post them.

Some of us like to go outside. We want to get the answer and use it. We do not want to understand every technology like you do. The ones we use all the time we’ll master. These other things – no chance.

Then there are the, “oh – a newbie question – what goes in the newbie section” responses. You know what? Bite me. Once again we are trying to solve a problem. Answers like that do not help. They piss us off.

There. I said it. I will probably loose my geek membership card but that’s okay with me.

by the way – here is the answer that worked for me:

/sbin/iptables -A INPUT -i eth0 -p tcp --dport mysql -j DROP /sbin/iptables -A INPUT -i eth0 -p udp --dport mysql -j DROP /sbin/iptables -I INPUT -i eth0 -p tcp -s 55.55.55.55 --dport mysql -j ACCEPT /sbin/iptables -I INPUT -i eth0 -p udp -s 55.55.55.55 --dport mysql -j ACCEPT

just replace 55.55.55.55 with the ip you need to allow

Disconnected Recordsets in ASP

admin — Mon, 12 Sep 2011 18:54:50 +0000

I am a huge fan of disconnected recordsets especially when we are displaying reports or any other database driven content on a web page. Once the data is returned to the recordset object, why maintain a connection to the database? Let it go do database things and let the web server play with the data. Here is my function. I call it getrs() because I am lazy. Most of it I copied from somewhere. I also assumes you have an open global database connection called db and a table called SQLError (for logging purposes).
Function GetRS(strSQL)Const adOpenStatic = 3 Const adUseClient = 3 Const adLockBatchOptimistic = 4
Dim oRS Set oRS = Server.CreateObject("ADODB.Recordset") oRS.CursorLocation = adUseClient on error resume next err.Clear oRS.Open strSQL, db, adOpenStatic, adLockBatchOptimistic if err <> 0 then dim rsx set rsx=server.CreateObject("adodb.recordset") rsx.open "select * from sqlerror where 1=2",db,3,2 rsx.addnew rsx("page")=request("page") rsx("sql")=strsql rsx("username")=session("uname") rsx.update rsx.close set rsx=nothing response.write "Your request created a system error. The error has been logged. Please make sure any fields you entered are the correct data types. " response.end end if Set oRS.ActiveConnection = Nothing Set GetRS = oRS End Function
And you use it like this:
set rs=getrs("select username from users") while not rs.eof response.write rs("username") & " " rs.movenext end %>
It is simple and makes reading your code pretty damned easy. An added benefit is that you can move to the end of the recordset with rs.movelast and then move to the first with rs.movefirst as often as you’d like.

Android Text Messaging and the Damned Small Fonts

admin — Sat, 10 Sep 2011 21:41:44 +0000

So – you can’t change the font settings on android phones. Stupid. Some of us have passed the big four oh and can’t see good any more. What’s my solution?

Download Handcent. It has a bazillion options – including fonts, colors, themes and it is free. It does have some ads in the admin section and i’d be happy to pay a buck or three to use this software. So far, I like it.
