我有幾個複選框過濾數據庫的結果,但我有兩個問題,第一個是我使用$_POST
變量,當我點擊刷新時,我得到一個確認表單提交對話框,其中我不要因爲用戶可能會多次刷新。複選框過濾不起作用
第二部分是,如果我用$_GET
替換$_POST
,我沒有看到確認消息,但複選框不起作用。任何人有任何想法?
<script type="text/javascript">
$(function(){
$('.checkbox').on('change',function(){
$('#form').submit();
});
});
</script>
<form id="id" method="post" action="">
<input type="checkbox" name="new" class="checkbox" <?php if(isset($_POST['new'])) echo "checked"; ?>/> New<br>
<input type="checkbox" name="used" class="checkbox" <?=(isset($_POST['used'])?' checked':'')?>/> Used<br>
<input type="checkbox" name="ref" class="checkbox" <?=(isset($_POST['ref'])?' checked':'')?>/> Refurbished<br>
</form>
if(isset($_GET['page']))
{
$page = $_GET['page'];
}
else
{
$page = 1;
}
$options = array(
'results_per_page' => 2,
'url' => 'products.php?search=' . urlencode($q) . '&page=*VAR*',
'db_handle' => $dbh
);
if (isset($_POST["ref"])) {
$arguments[] = " condition LIKE '%refur%' ";
}
if (isset($_POST["new"])) {
$arguments[] = " condition LIKE '%new%' ";
}
if (isset($_POST["used"])) {
$arguments[] = " condition LIKE '%use%' ";
}
if(!empty($arguments)) {
$str = implode(' or ',$arguments);
$qry = "SELECT * FROM products where " . $str . " ORDER BY id desc";
$paginate = new pagination($page, $qry, $options);
echo $qry;
}
else {
$paginate = new pagination($page, "SELECT * FROM products order by id desc", $options);
}
