Hi !
In our applications, it's not always easy to comply with MVC rules.
I thought it could be great to describe a page with a library, OOP.
I wrote a small and very very very simple library named "HTMLTag", to comply with MVC rules in my CRUD automated library.
So, here an using example :
Code:
$this->load->library('HTMLTag');
$page = new HTMLTag('body',
array('class'=>'lalala'),
array(
new HTMLTag('div', array('class'=>'totototot'),
new HTMLTag('form', array('method'=>'post'),
new HTMLTag('input',array('type'=>'button'))
)
),
new HTMLTag('p', array('style'=>"font-weight:bold;"), "Hi there !!")
)
);
echo $page;
Output (with automatic indentation) :
Code:
<body class="lalala">
<div class="totototot">
<form method="post">
<input type="button" />
</form>
</div>
<p >
Hi there !!
</p>
</body>
It could be helpful to manage interfaces, buttons, etc.
We can extend this library to specific usage (automated form interactions for example, or ajax forms, etc.).
Here the class code :
Code:
