meta data help

cerberus478 · September 14, 2011

I would like to be able to have my meta data pick out the information of a page and insert it into the meta tags.

I have a controller class which has the coding to get the data, which is this:

controller.class.php

function get_title(){

	$title='';

	if (isset($this->_params['item']['meta_title'])  && !empty($this->_params['item']['meta_title'])){

		$title=$this->_params['item']['meta_title'];


	}

	$title=strip_tags($title);

	$title=str_replace('"', '\'', $title);

	$title=trim($title);

	if (strlen($title)>150){

		$end_of_last_sentence=strpos($title, '.', 150)+1;

	if ($end_of_last_sentence<150){

			$end_of_last_sentence=150;

		}

		$title=substr($title, 0, $end_of_last_sentence);

	}

		return $title;
}


function get_description(){


	$description='';

	if (isset($this->_params['item']['meta_description'])  && !empty($this->_params['item']['meta_description'])){

		$description=$this->_params['item']['meta_description'];

	}

	$description=strip_tags($description);

	$description=str_replace('"', '\'', $description);

	$description=trim($description);

	if (strlen($description)>150){

		$end_of_last_sentence=strpos($description, '.', 150)+1;

		if ($end_of_last_sentence<150){

			$end_of_last_sentence=150;

		}

		$description=substr($description, 0, $end_of_last_sentence);

	}

	return $description;

}


function get_keywords(){

	$keyword='';

	if (isset($this->_params['item']['meta_keyword'])  && !empty($this->_params['item']['meta_keyword'])){

		$keyword=$this->_params['item']['meta_keyword'];


	}

	$keyword=strip_tags($keyword);

	$keyword=str_replace('"', '\'', $keyword);

	$keyword=trim($keyword);

	if (strlen($keyword)>150){

		$end_of_last_sentence=strpos($keyword, '.', 150)+1;

		if ($end_of_last_sentence<150){

			$end_of_last_sentence=150;

		}

		$keyword=substr($keyword, 0, $end_of_last_sentence);

	}

	return $keyword;
	}

Then I have a pages.controller which has the coding for the home page

pages.controller.php

public function home(){
	//instantiate a model
	$galleries_model = new galleries_model('galleries');
	$galleries = $galleries_model -> get_all();


	foreach($galleries as $gallery){


		//how to loop through an image so that only the first
		//image is selected
		$sql = "SELECT image_path FROM gallery_images 
				WHERE 
						gallery_id = {$gallery['id']}
				ORDER BY order_by";

		$image = $this->_model->get_one($sql);

		$gallery['image'] = $image;
		$this->_params['list'][] = $gallery;

	}

	$this->_params['item'] = $this->_model->get(array("pages.name = 'home'"));

}

galleries.controller.php
public function galleries(){

	$galleries = $this->_model->get_all();


	$this->_params['list'] = $galleries;


}

public function view($gallery_id){

	$this->_params['item'] = $this->_model->get($gallery_id);

	$this->_params['item'] ;
	//die;

}

This is my default page where I want the meta tags to echo out the relevent information

default.php

!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title><?php echo $this->get_title(); ?></title>
<meta name="Description" content="<?php echo $this->get_description(); ?>" />
<meta name="Keywords" content="<?php echo $this->get_keywords(); ?>" />
<title>Welcome to the Framework</title>
<?php
$this->_page->add_javascript('/vendor/lightbox/js/jquery.lightbox-0.5.min.js');
$this->_page->add_stylesheet('/vendor/lightbox/css/jquery.lightbox-0.5.css');
echo $this->page('stylesheets');
echo $this->page('javascripts');
?>

</head>
<body>


<h1>
Welcome to the My site
</h1>


<?php echo $this->page('view');?>
</body>
</html>

In the pages.controller.php I managed to get it to work using $this->_params['item'] = $this->_model->get(array("pages.name = 'home'"));

I want to be able to do the same thing on different pages but I can't get it to work.

I hope I explained it clearly.

Thank you

Hoping this is the answer you want

//$content - pahe infor 
<meta  http-equiv="content-type" content="<?php echo  $content; ?>" />

thanks for replying where would I put the $content because if I put it into my default.php I get a warning saying that $content is undefined.

I forgot to mention that on my home page I have 2 links and in the galleries.controller.php is where the database picks up the gallery names and displays them in the links, so when I click the link it goes to the gallery 1 page for example.
