search form to return results between dates

**ianhaney** · 02-10-2016, 01:25 PM

Hi

I have got the results paginated but now need to include a form to search for data between two dates but am stuck

My code looks like the following but returns the errors

Code:

<?php

ini_set('display_startup_errors',1);
ini_set('display_errors',1);
error_reporting(-1);

include_once("mysqli_connection.php");

// This first query is just to get the total count of rows
$sql = "SELECT COUNT(id) FROM purchased_software";

$r = mysqli_query($con,$sql)
  or die("Error: ".mysqli_error($con));

$query = mysqli_query($con, $sql);
$row = mysqli_fetch_row($query);
// Here we have the total row count
$rows = $row[0];
// This is the number of results we want displayed per page
$page_rows = 5;
// This tells us the page number of our last page
$last = ceil($rows/$page_rows);
// This makes sure $last cannot be less than 1
if($last < 1){
	$last = 1;
}
// Establish the $pagenum variable
$pagenum = 1;
// Get pagenum from URL vars if it is present, else it is = 1
if(isset($_GET['pn'])){
	$pagenum = preg_replace('#[^0-9]#', '', $_GET['pn']);
}
// This makes sure the page number isn't below 1, or more than our $last page
if ($pagenum < 1) { 
    $pagenum = 1; 
} else if ($pagenum > $last) { 
    $pagenum = $last; 
}
// This sets the range of rows to query for the chosen $pagenum
$limit = 'LIMIT ' .($pagenum - 1) * $page_rows .',' .$page_rows;

$a = ( isset($_POST['from']) ) ? $_POST['from'] : '';
$b = ( isset($_POST['to']) ) ? $_POST['to'] : '' ;

// This is your query again, it is for grabbing just one page worth of rows by applying $limit
$sql = "SELECT id, customer_pp_email, sales_month, software_title, quantity, total_sale, ebay_fees, paypal_fees, software_cost, profit, notes, status, sold_by FROM purchased_software 
WHERE sales_month BETWEEN '$a' AND '$b' ORDER BY id DESC $limit";

//var_dump($_POST);

print_r($_POST);

$query = mysqli_query($con, $sql);

// This shows the user what page they are on, and the total number of pages
$textline1 = "Sales (<b>$rows</b>)";
$textline2 = "Page <b>$pagenum</b> of <b>$last</b>";
// Establish the $paginationCtrls variable
$paginationCtrls = '';
// If there is more than 1 page worth of results
if($last != 1){
	/* First we check if we are on page one. If we are then we don't need a link to 
	   the previous page or the first page so we do nothing. If we aren't then we
	   generate links to the first page, and to the previous page. */
	if ($pagenum > 1) {
        $previous = $pagenum - 1;
		$paginationCtrls .= '<a href="'.$_SERVER['PHP_SELF'].'?pn='.$previous.'">Previous</a> &nbsp; &nbsp; ';
		// Render clickable number links that should appear on the left of the target page number
		for($i = $pagenum-4; $i < $pagenum; $i++){
			if($i > 0){
		        $paginationCtrls .= '<a href="'.$_SERVER['PHP_SELF'].'?pn='.$i.'">'.$i.'</a> &nbsp; ';
			}
	    }
    }
	// Render the target page number, but without it being a link
	$paginationCtrls .= ''.$pagenum.' &nbsp; ';
	// Render clickable number links that should appear on the right of the target page number
	for($i = $pagenum+1; $i <= $last; $i++){
		$paginationCtrls .= '<a href="'.$_SERVER['PHP_SELF'].'?pn='.$i.'">'.$i.'</a> &nbsp; ';
		if($i >= $pagenum+4){
			break;
		}
	}
	// This does the same as above, only checking if we are on the last page, and then generating the "Next"
    if ($pagenum != $last) {
        $next = $pagenum + 1;
        $paginationCtrls .= ' &nbsp; &nbsp; <a href="'.$_SERVER['PHP_SELF'].'?pn='.$next.'">Next</a> ';
    }
}
$list = '';
while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){
	$id = $row["id"];
	$customer_pp_email = $row["customer_pp_email"];
	$sales_month = strftime("%b %d, %Y", strtotime($sales_month));
	$software_title = $row["software_title"];
	$quantity = $row["quantity"];
	$total_sale = $row["total_sale"];
	$ebay_fees = $row["ebay_fees"];
	$paypal_fees = $row["paypal_fees"];
	$software_cost = $row["software_cost"];
	$profit = $row["profit"];
	$notes = $row["notes"];
	$status = $row["status"];
	$sold_by = $row["sold_by"];
	$list .= '<p>' . $customer_pp_email . $sales_month . $software_title . $quantity . $total_sale . $ebay_fees . $paypal_fees . $software_cost . $profit . $notes . $status . $sold_by.'</p>';
}
// Close your database connection
mysqli_close($con);

The print post returns Array ( )

Can anyone help or point me in the right direction please
