Here is the snippet to fetch all content from "form" table with table format and pager. Also you can add condition which I have added in comment if required.
<?php
// Set header
$header = array(
array('data' => t('Name'), 'field' => 'name'),
array('data' => t('Email'), 'field' => 'email'),
array('data' => t('Subject'), 'field' => 'subject'),
array('data' => t('Message'), 'field' => 'message'),
);
//query to fetch all content
$query = db_select('form', 'f');
$query->fields('f');
//$query->condition('f.name', $search_name, '=') //if needed
$table_sort = $query->extend('TableSort') // Table sort extender
->orderByHeader($header); // Order by headers
$pager = $table_sort->extend('PagerDefault')
->limit(20); // Set page limit
$arr_result = $pager->execute();
$rows = array();
foreach($arr_result as $result) {
$rows[] = array(
$result->name,
$result->email,
$result->subject,
$result->message,
);
}
// Set empty output
$output = '';
if (!empty($rows)) {
$output = theme('table', array(
'header' => $header,
'rows' => $rows,
/*'attributes' => array(
'id' => 'sort-table' // add if want to add sorting
) */
));
$output .= theme('pager');
}
else {
$output .= t("No results found.");
}
return $output;
?>
Let me know if any query/confusion occurs for the same.
