I thought I’d share this, maybe it’ll help somebody else. Basically this will take the value of the drop down (select) and show() that many input fields.

Javascript

$(document).ready(function(){
        $("select[name=example]").change(function () {
        $(".hidden_input").hide();
        var cnt = $("select[name=example]").val();  
            
            while(cnt > 0) {
                $(".hidden_input#"+cnt).show();
                cnt--;  
            }
            
        });
     
});

HTML/CSS

<style>
.hidden_input{
    display: none;
}
</style>
<form>
    <select name="example">
        <option value="1">1 Guests</option>
        <option value="2">2 Guests</option>
        <option value="3">3 Guests</option>
        <option value="4">4 Guests</option>
        <option value="5">5 Guests</option>
        <option value="6">6 Guests</option>
    </select>
</form>
<div id="1" class="hidden_input">1<input name="former" type="text"></div>
<div id="2" class="hidden_input">2<input name="former" type="text"></div>
<div id="3" class="hidden_input">3<input name="former" type="text"></div>
<div id="4" class="hidden_input">4<input name="former" type="text"></div>
<div id="5" class="hidden_input">5<input name="former" type="text"></div>
<div id="6" class="hidden_input">6<input name="former" type="text"></div>

Ran into a problem last night where a long email was messing up a design in smaller screen resolutions.

Perfect fix down below:

pre {
white-space: pre; /* CSS 2.0 */
white-space: pre-wrap; /* CSS 2.1 */
white-space: pre-line; /* CSS 3.0 */
white-space: -pre-wrap; /* Opera 4-6 */
white-space: -o-pre-wrap; /* Opera 7 */
white-space: -moz-pre-wrap; /* Mozilla */
white-space: -hp-pre-wrap; /* HP Printers */
word-wrap: break-word; /* IE 5+ */ }

Thanks to perishable press for this one, read more about it here .

So in WordPress with plugins etc. you end up using shortcode in posts to keep things simple, an example would be if you want to display a gallery you would just use:

[galleries id="1"]

However trying to this when your outside of the “WordPress Loop” (in your theme files usually) you will hit the problem that WordPress won’t parse the shortcode.

The solution is very simple, just append the following to your shortcode:

echo apply_filters('the_content', '[galleries id="1"]');

And it works!

So this post may not be to everyone’s taste, its more a post to remind myself why I’ve decided to learn Perl. If anyone doesn’t know I already know PHP and Java.

Perl is a programming language, It’s Object Oriented, simple to learn and very powerful. Perl stands for: “Practical Extraction and Reporting Language” but others have come up with many more interesting and colorful names for it;

Perl is “the little language that could” it’s designed to be able to do as many tasks as possible in as little time as possible.

“A good perl program is one that gets the job done before your boss fires you.” Larry Wall, the creator of Perl.

Perl is an Interpreted language, so you don’t have to compile it like you do Java, C, C++ etc. For fast development work, that’s a godsend.

Perl has been successfully used for a lot of diverse tasks: text processing, system administration, web programming, web automation, GUI programming, games programming, code generation, bio-informatics and genealogical research, lingual and etymological research, number crunching, and testing and quality assurance.

Perl Pros

• Cross Platform compatibility. A perl script for linux/unix will work just as well in windows and vice versa, and the only exceptions to that rule are those dictated by the operating system itself. (for example file paths are different in windows and unix.)
• Online support. Perl has been around since the early 90’s, its exceptionally well known and thousands of tutorial and help sites abound on the internet.
• CPAN.org, a massive collection of perl modules that can do almost anything, someone has usually done the work for you.
• Taint mode, this helps you to write secure code by not trusting any data provided by the users until you have tested and declared it safe.

Perl Cons

• Speed. Apparently with a very large program (Like word or something) the sheer size of it would make it extremely slow to compile at runtime.. This is the only Con I’ve found about Perl!

Update as of August 2020 - PyroCMS now relies upon Laravel.

So lately I’ve been playing around with PyroCMS , for any of you who don’t know about Pyro, its basically an open source content management solution that iss based on the CodeIgnitor framework. What does that mean you ask?

• MVC design pattern. (Model->View->Controller)
• Security, Cross-Site Request Forgery protection, XSS filtering and very secure password encryption.
• Caching, in order to achieve maximum performance.
• Translated into 16 languages!
• Extremely lightweight!
• Support for modules, themes, plugins and widgets!
• Multi – Site Manager (In Pro Version £45 )

Really it takes the pain out of making your standard websites, you’ll have an area where the client can update their website in a simple environment and thanks to ‘permissions’ you can be sure they won’t mess anything up!

Of course there is always going to be a stage when your better off without a framework, but for projects that it will work for, PyroCMS will save you a BUNCH of time!
