I just saw the announcement for Google’s revised reCAPTHCA API, so I decided threw together a quick example. It worked well without even looking at the documentation. So simple to integrate it’s ridiculous. Here is the PHP (no security for simplicity)… Continue reading

PHP: Check MySQL database to see if table, field, or value exists
This procedural function will tell you if the table you are looking for is found within your currently selected MySQL database. Optionally, it will also determine if a column exists within the specified table. You can even pass the a value as the optional third parameter to see if the field’s value is also what you expect.

PHP: Validate XML String While Suppressing Errors
Here you go…
libxml_use_internal_errors(TRUE); $foo = @simplexml_load_string($bar); if ($foo === FALSE) { //Invalid XML } else { //$bar is XML }
If you want to display/log the errors…
foreach (libxml_get_errors() as $error) { //do something with $error->message } libxml_clear_errors();
Cheers 😀
SQL SELECT NOT DISTINCT (duplicate values)
Simply replace table and column
SELECT COUNT(*), * FROM `table` GROUP BY `column` HAVING COUNT(*) > 1;
Quickly Hide Trending Tags and Topics from Facebook
Here is a bookmarklet you can use to quickly hide the “Trending” [Tags and Topics] panel from your Facebook wall…
javascript:document.getElementById('pagelet_trending_tags_and_topics').style.display='none';void(0);
That should work in nearly all modern browsers since it uses basic JavaScript that has worked for quite some time to apply element styles.
You may also be able to right-click the following link and save it as a bookmark 😉
Automatically expand textarea to fit content using jQuery without autogrow or autosize plugins
I’m sure there is a more efficient way to do this, but it suited my needs.
<script> $(function() { $('textarea').keyup(function(){ $(this).each(function(index, element) { $(element).height(element.scrollHeight); }); }).keyup(); //trigger event to initialize pre-filled textareas }); </script>
Enjoy 🙂
CodeIgniter: Load View from Database (more or less)
I have seen a few people asking how to load a view from a database (or something other than a physical file in the “views” folder).
In my particular case, a client wants the ability to edit HTML and TEXT email templates. Without giving them direct access to editing the physical files, I decided to move the views being used for email to the database instead. Continue reading
Email Delivery Codes: Errors
Every time when your email cannot be delivered, the SMTP server sends you a notification, which includes a standard error message, associated with the real problem. Each code is composed of three digits (X.X.X). The first digit gives the status of the email message: Continue reading

Recursively set permissions (CHMOD) for a specific file extension
Just a quick snippet…
find /start/from/here -type f -name "*.php" -print | xargs chmod 644

Easily convert MySQL database collations and alter character sets
I can’t remember what all I looked at for references, but this completed tool will generate the SQL commands necessary to convert your database, tables and fields from any collation and character set into another.
It goes without saying to make a backup of your database before running such commands. If you don’t make a backup first, shame on you 😛 Continue reading
Using chown recursively with a reference file
Nothing too complicated 😉
-R > recursive (includes all folders/files)
–reference=. > get owner:group from the current folder (eg: single dot)
. > start in current directory
chown -R --reference=. .
This comes in pretty handy when migrating sites using gzipped archives 😀
