这是一个有效的解决方案(按原样测试)
The HTML (could be part of page content)
<input type="text" name="keyword" id="keyword" onkeyup="fetch()"></input>
<div id="datafetch">Search results will appear here</div>
The JavaScript ( goes to your theme\'s functions.php )
// add the ajax fetch js
add_action( \'wp_footer\', \'ajax_fetch\' );
function ajax_fetch() {
?>
<script type="text/javascript">
function fetch(){
jQuery.ajax({
url: \'<?php echo admin_url(\'admin-ajax.php\'); ?>\',
type: \'post\',
data: { action: \'data_fetch\', keyword: jQuery(\'#keyword\').val() },
success: function(data) {
jQuery(\'#datafetch\').html( data );
}
});
}
</script>
<?php
}
And finally the AJAX call 转到主题的功能。php
// the ajax function
add_action(\'wp_ajax_data_fetch\' , \'data_fetch\');
add_action(\'wp_ajax_nopriv_data_fetch\',\'data_fetch\');
function data_fetch(){
$the_query = new WP_Query( array( \'posts_per_page\' => -1, \'s\' => esc_attr( $_POST[\'keyword\'] ), \'post_type\' => \'post\' ) );
if( $the_query->have_posts() ) :
while( $the_query->have_posts() ): $the_query->the_post(); ?>
<h2><a href="<?php echo esc_url( post_permalink() ); ?>"><?php the_title();?></a></h2>
<?php endwhile;
wp_reset_postdata();
endif;
die();
}
补充:下面是我如何精确搜索AJAX函数的:
// the ajax function
add_action(\'wp_ajax_data_fetch\' , \'data_fetch\');
add_action(\'wp_ajax_nopriv_data_fetch\',\'data_fetch\');
function data_fetch(){
$the_query = new WP_Query(
array(
\'posts_per_page\' => -1,
\'s\' => esc_attr( $_POST[\'keyword\'] ),
\'post_type\' => \'post\'
)
);
if( $the_query->have_posts() ) :
while( $the_query->have_posts() ): $the_query->the_post();
$myquery = esc_attr( $_POST[\'keyword\'] );
$a = $myquery;
$search = get_the_title();
if( stripos("/{$search}/", $a) !== false) {?>
<h4><a href="<?php echo esc_url( post_permalink() ); ?>"><?php the_title();?></a></h4>
<?php
}
endwhile;
wp_reset_postdata();
endif;
die();
}
