theme_pager to modify drupal pagination
I have the following theme_pager function inside template.php. The problem is , the "showing 1-25 of 200" gets displayed after each page number. How do i get it to display just once at the top.
function themename_pager($tags = array(), $limit = 10, $element = 0, $parameters = array(), $quantity = 9) {
global $pager_page_array, $pager_total;
$tags = array("", "< prev", "", "next >", "");
// Calculate various markers within this pager piece:
// Middle is used to "center" pages around the current page.
$pager_middle = ceil($quantity / 2);
// current is the page we are currently paged to
$pager_current = $pager_page_array[$element] + 1;
// first is the first page listed by this pager piece (re quantity)
$pager_first = $pager_current - $pager_middle + 1;
// last is the last page listed by this pager piece (re quantity)
$pager_last = $pager_current + $quantity - $pager_middle;
// max is the maximum page number
$pager_max = $pager_total[$element];
// End of marker calculations.
// Prepare for generation loop.
$i = $pager_first;
if ($pager_last > $pager_max) {
// Adjust "center" if at end of query.
$i = $i + ($pager_max - $pager_last);
$pager_last = $pager_max;
}
if ($i <= 0) {
// Adjust "center" if at start of query.
$pager_last = $pager_last + (1 - $i);
$i = 1;
}
// End of generation loop preparation.
$view = views_get_current_view();
// ensure view exists
if (!$view) return;
// set object property to return total rows
$view->get_total_rows = true;
// set display_id
$view->set_display($display_id);
// execute view
$view->execute();
// acquire data from views object and $_REQUEST
$itemsPerPage = $view->pager['items_per_page'];
$currentPage = $_REQUEST['page']+1;
$total = $view->total_rows;
// start calculation
$start = 25*$currentPage-24;
$end = $itemsPerPage * $currentPage;
if ($end>$total) $end = $total;
// return html
$x = "<center>Displaying $start - $end of $total</center>";
$li_previous = theme('pager_previous', (isset($tags[1]) ? $tags[1] : t('‹ previous')), $limit, $element, 1, $parameters);
$li_next = theme('pager_next', (isset($tags[3]) ? $tags[3] : t('next ›')), $limit, $element, 1, $parameters);
if ($pager_total[$element] > 1) {
if ($li_previous) {
$items[] = array(
'class' => 'pager-previous',
'data' => $li_previous,
);
}
// When there is more than one page, create the pager list.
if ($i != $pager_max) {
// Now generate the actual pager piece.
for (; $i <= $pager_last && $i <= $pager_max; $i++) {
if ($i < $pager_current) {
if ($pager_first > 1 && $i == $pager_first) {
$output = '...'.$i;
$stopPreEllipsis = true;
} else {
$output = $i;
}
$items[] = array(
'class' => 'pager-item',
'data' => theme('pager_previous', $output, $limit, $element, ($pager_current - $i), $parameters),
);
}
if ($i == $pager_current) {
$items[] = array(
'class' => 'pager-current',
'data' => $i,
);
}
if ($i > $pager_current) {
if ($p开发者_开发技巧ager_last < $pager_max && $i == $pager_last) {
$output = $i.'...';
} else {
$output = $i;
}
$items[] = array(
'class' => 'pager-item',
'data' => theme('pager_next', $output, $limit, $element, ($i - $pager_current), $parameters),
);
$items[] = array(
'class' => 'pager',
'data' => $x,
);
}
}
}
// End generation.
if ($li_next) {
$items[] = array(
'class' => 'pager-next',
'data' => $li_next,
);
}
return theme('item_list', $items, NULL, 'ul', array('class' => 'pager'));
}
}
Remove these lines:
$items[] = array(
'class' => 'pager',
'data' => $x,
);
And return $x
before the list of pager items like this (change the last line):
return $x . theme('item_list', $items, NULL, 'ul', array('class' => 'pager'));
