retrieve variable

[snrecords]

Hi all.

 

I have a search page with a html form that passes several variables through.

 

My results page retrieves the data using $_POST.

 

My results page also uses the include statement to include my pagination code.

 

The pagination code uses php functions which makes things easier BUT, I can't figure out why I can't retrieve my $_POST data and put it in one of the function of the pagination code.

 

The pagination code is below:

class PS_Pagination {
var $php_self;
var $rows_per_page; //Number of records to display per page
var $total_rows; //Total number of rows returned by the query
var $links_per_page; //Number of links to display per page
var $sql;
var $debug = false;
var $conn;
var $page;
var $max_pages;
var $offset;

/**
 * Constructor
 *
 * @param resource $connection Mysql connection link
 * @param string $sql SQL query to paginate. Example : SELECT * FROM users
 * @param integer $rows_per_page Number of records to display per page. Defaults to 10
 * @param integer $links_per_page Number of links to display per page. Defaults to 5
 */

function PS_Pagination($connection, $sql, $rows_per_page = 10, $links_per_page = 5) {
	$this->conn = $connection;
	$this->sql = $sql;
	$this->rows_per_page = $rows_per_page;
	$this->links_per_page = $links_per_page;
	$this->php_self = htmlspecialchars($_SERVER['PHP_SELF']);
	if(isset($_GET['page'])) {
		$this->page = intval($_GET['page']);
	}
}

/**
 * Executes the SQL query and initializes internal variables
 *
 * @access public
 * @return resource
 */
function paginate() {
	if(!$this->conn) {
		if($this->debug) echo "MySQL connection missing<br />";
		return false;
	}

	$all_rs = @mysql_query($this->sql);
	if(!$all_rs) {
		if($this->debug) echo "SQL query failed. Check your query.<br />";
		return false;
	}
	$this->total_rows = mysql_num_rows($all_rs);
	@mysql_close($all_rs);

	$this->max_pages = ceil($this->total_rows/$this->rows_per_page);
	//Check the page value just in case someone is trying to input an aribitrary value
	if($this->page > $this->max_pages || $this->page <= 0) {
		$this->page = 1;
	}

	//Calculate Offset
	$this->offset = $this->rows_per_page * ($this->page-1);

	//Fetch the required result set
	$rs = @mysql_query($this->sql." LIMIT {$this->offset}, {$this->rows_per_page}");
	if(!$rs) {
		if($this->debug) echo "Pagination query failed. Check your query.<br />";
		return false;
	}
	return $rs;
}

/**
 * Display the link to the first page
 *
 * @access public
 * @param string $tag Text string to be displayed as the link. Defaults to 'First'
 * @return string
 */
function renderFirst($tag='First') {
	if($this->page == 1) {
		return $tag;
	}
	else {
		return '<a href="'.$this->php_self.'?page=1">'.$tag.'</a>';
	}
}

 

When i put echo $_POST['myvariable']; outside of the functions it works, but when i put it inside it doesn't.  I just want to make the link below include my $_POST['myvariable']. 

 

function renderFirst($tag='First') {
	if($this->page == 1) {
		return $tag;
	}
	else {
		return '<a href="'.$this->php_self.'?page=1">'.$tag.'</a>';
	}

 

Please help!

$postvalues=$_POST['myvariable'];
class PS_Pagination {

var $postvalues;
function urfunction{

echo $this->$postvalues;

}

Hi!

<?php
function renderFirst($tag='First', $your_variable) {
      // do whatever you want with $your_variable
      if($this->page == 1) {
         return $tag;
      }
      else {
         return '<a href="'.$this->php_self.'?page=1">'.$tag.'</a>';
      }
}
?>

 

<?php

$pagination = new PS_Pagination();

$your_variable = $pagination->renderFirst('First', $your_variable);
?>
