CSML

Generate HTML tags from CSS selectors.

When writting CakePHP views or WordPress templates I hate mixing large chunks of PHP with with HTML and and I loathe echoing HTML tags as concatenated strings. Also I always forget the order of the arguments in frameworks’ HTML helpers.

So, this is a very simple way to generate HTML tags without leaving your <?php ?> blocks using a simple syntax that looks a lot like CSS selectors.

The file csml.php contains the csml class and two helper functions: t() and en() to make lazy people like me, even happier.

t($selector)

This function takes a CSS…ish selector and outputs an HTML tag.


<?php
	t('div#container.index'); // output: <div id="container" class="index">
		echo "lorem ipsum dolor sit amet";
	t('/div') // output: </div>	
?>

As you can see in the example above, in order to close a tag, you only have to put a slash (/) before the tag. If you use a selector with id’s and/or classes, it will append a helpfull comment to the closing tag. Very useful when you are examining your source.


<?php
	t('div#container'); // output: <div id="container" class="index">
		echo "lorem ipsum dolor sit amet";
	t('/div#container') // output: </div> <!-- /#container -->	
?>

For autoclosing tags just append the slash at the end of the tag name:


<?php
	t('br/.clear'); // output: <br class="clear"/>
?>

You can have only one id per tag, but as any classes as you want, separated by dots. Only remember: id’s always has to be declared before classes.


<?php
	t('div#an-id.a-class.another-class.yet-another-class'); // this works as expected.
	t('div.a-class.another-class.yet-another-class'); // this works too
	t('div.#an-id'); // and this!
	t('div.a-class.another-class#an-id'); // This is dangerous and could kill some kittens
?>

Attributes

If you need to pass extra attributes to your tag, you have to options:

1: You can declared them right into your selector using something like CSS PseudoClases. Example:


<?php

// useful for links
t(‘a.button[href=“http://google.com” title=“google something”]’);
echo “Go to Google”;
t(‘/a’);

// or images
t(‘img.button[src=“image.jpg” alt=“A beautiful image”]/’);
?>

2: Sometimes you want to generate attributes from some other PHP code, and excessive concatenation looks ugly. So you can pass an associative array of attributes as the second parameter.


<?php

	t('a.button',array('href'=>'http://google.com','title'=>'google something')); 
?>

en($content,$selector);

This function will enclose any string within other tags generated from the passed selector or selectors. Example:


<?php
	// useful for links
	en("Go to Google",'a.button[href="http://google.com"]');
	// output: <a href="http://google.com"" class="button">Go to Google</a>
?>

If the second argument is an array of selectors, then the content will be nested into all this selectors, being the last one, the deepest level.


<?php
	// useful for links
	$selectors = array(
		'ul.navigation',
		'li',
		'a.button[href="http://google.com]',
		);
	en("Go to Google",$selectors);
	// output: <ul class="navigation><li><a href="http://google.com"" class="button">Go to Google</a></li></ul>
?>

Requirements

This class requires PHP 5.2 and a can of Diet Coke.

Epilogue

Please take into consideration that I’m not a real programmer, so if you find some obvious or clever way to make this little class better, feel free to fork it. Please.

Also, if you find it useful and actually use it, let me know. I’m just starting in this OpenSource thing and I may need to get excited :P

  • Both functions have more arguments, but you have to read the source for those.
You can’t perform that action at this time.
