Pagination next page should be 2 but is 0 - php

Question

The first page should be 1 but its -1 and the next page should be 2 but its 0.
How can I make this work? I have tried to edit the $page but when I do, the if/else get wierd.
I added the whole code...
...
$resultt= "SELECT * FROM users WHERE AND country='$okc' AND state='$oks'";
if(!empty($a1) && empty($a2)){
$resultt .= " AND aar>=";
...
}
There are more than 1 if statement.
$result = mysqli_query($con,"$resultt");
$rec_limit = 19;
$row = mysqli_fetch_array($result);
$rec_count = $row[0];
if( isset($_GET['page'] ) )
{
$page = $_GET['page'] + 1;
$offset = $rec_limit * $page ;
}
else
{
$page = 0;
$offset = 0;
}
$left_rec = $rec_count - ($page * $rec_limit);
$resultt .= "LIMIT $offset, $rec_limit";
$sql = $resultt;
$retval = mysqli_query( $con, "$resultt" );
if( $page > 0 )
{
$last = $page - 1;
echo "Last 10 Records |";
echo "Next 10 Records";
}
else if( $page == 0 )
{
echo "Next 10 Records";
}
else if( $left_rec < $rec_limit )
{
$last = $page - 2;
echo "Last 10 Records";
}
while($row = mysqli_fetch_array($retval, MYSQL_ASSOC))
{
}

Answer 1

You should change parts of code to get it to work. $_GET['page'] should give you the queried page number itself, so don't try to manipulate it.
$sql = "SELECT * FROM users WHERE country='$okc' AND state='$oks'"
$rec_limit = 10;
$result = mysqli_query( $con, $sql );
$row = mysqli_fetch_array( $result );
$rec_count = $row[0];
$left_rec = $rec_count - ( $rec_limit * $page );
$page = isset($_GET['page']) ? intval($_GET['page']) : 1;
$offset = $rec_limit * ( $page - 1 ) ;
$sql.= " LIMIT $rec_limit OFFSET $offset";
$result = mysqli_query( $con, $sql );
$row = mysqli_fetch_array( $result );
if( $page > 1 ){
$last = $page - 1;
echo "Last 10 Records |";
echo "Next 10 Records";
}else if( $page == 1 ){
echo "Next 10 Records";
}else if( $left_rec < $rec_limit ){
$last = $page - 2;
echo "Last 10 Records";
}
while( $row = mysqli_fetch_array( $result, MYSQL_ASSOC ) ){
// use $row to echo row contents ...
}

Answer 2

$_GET is an array like your $row.
to access array keys you always use [].
change your get into $_GET['page']
even better:
$page = isset($_GET['page']) ? intval($_GET['page']) : 1;
is page set then convert value to int, because you dont know whats incomming.
if not set take page 1.
btw. constructs like this:
$resultt = "LIMIT $offset, $rec_limit";
can/will cause sql injections bugs within you homepage!
never build a sql with variables!
Use parameters instead!
