【问题描述】:
我正在尝试在pagination 中实现live search。我可以插入在按回车后起作用的静态搜索按钮。我想实现实时搜索按钮而不是这个。当我尝试使用 ajax 时,我无法处理,它搞砸了。
以下是我的分页和搜索代码。如何使用实时搜索而不是跟随静态搜索?我是ajax新手。或者请提供教程链接以在分页中创建实时搜索。
<?php
$search_keyword = '';
if(!empty($_POST['search']['keyword'])) {
$search_keyword = $_POST['search']['keyword'];
}
$sql = 'SELECT * FROM posts WHERE post_title LIKE :keyword OR description LIKE :keyword OR post_at LIKE :keyword ORDER BY id DESC ';
/* Pagination Code starts */
$per_page_html = '';
$page = 1;
$start=0;
if(!empty($_POST["page"])) {
$page = $_POST["page"];
$start=($page-1) * ROW_PER_PAGE;
}
$limit=" limit " . $start . "," . ROW_PER_PAGE;
$pagination_statement = $pdo_conn->prepare($sql);
$pagination_statement->bindValue(':keyword', '%' . $search_keyword . '%', PDO::PARAM_STR);
$pagination_statement->execute();
$row_count = $pagination_statement->rowCount();
if(!empty($row_count)){
$per_page_html .= "<div style='text-align:center;margin:20px 0px;'>";
$page_count=ceil($row_count/ROW_PER_PAGE);
if($page_count>1) {
for($i=1;$i<=$page_count;$i++){
if($i==$page){
$per_page_html .= '<input type="submit" name="page" value="' . $i . '" class="btn-page current" />';
} else {
$per_page_html .= '<input type="submit" name="page" value="' . $i . '" class="btn-page" />';
}
}
}
$per_page_html .= "</div>";
}
$query = $sql.$limit;
$pdo_statement = $pdo_conn->prepare($query);
$pdo_statement->bindValue(':keyword', '%' . $search_keyword . '%', PDO::PARAM_STR);
$pdo_statement->execute();
$result = $pdo_statement->fetchAll();
?>
<form name='frmSearch' action='' method='post'>
<div style='text-align:right;margin:20px 0px;'><input type='text' name='search[keyword]' value="<?php echo $search_keyword; ?>" id='keyword' maxlength='25'></div>
<table class='tbl-qa'>
<thead>
<tr>
<th class='table-header' width='20%'>Title</th>
<th class='table-header' width='40%'>Description</th>
<th class='table-header' width='20%'>Date</th>
</tr>
</thead>
<tbody id='table-body'>
<?php
if(!empty($result)) {
foreach($result as $row) {
?>
<tr class='table-row'>
<td><?php echo $row['post_title']; ?></td>
<td><?php echo $row['description']; ?></td>
<td><?php echo $row['post_at']; ?></td>
</tr>
<?php
}
}
?>
</tbody>
</table>
<?php echo $per_page_html; ?>
</form>
