1.多图参数整合
foreach ($files[‘name‘] as $key => $value) {
if ($files[‘name‘][$key] && !preg_match(‘/[\x{4e00}-\x{9fa5}]/u‘, $files[‘name‘][$key]) > 0){
$file = array(
‘name‘ => $files[‘name‘][$key],
‘type‘ => $files[‘type‘][$key],
‘tmp_name‘ => $files[‘tmp_name‘][$key],
‘error‘ => $files[‘error‘][$key],
‘size‘ => $files[‘size‘][$key]
);
$_FILES = array("up_file" => $file);
foreach ($_FILES as $file => $array) {
$newupload = my_handle_attachment($file, $pid = 0);
}
$attach_id[] = $newupload;
$name[] = $files[‘name‘][$key];
$type[] = $files[‘type‘][$key];
}else{
echo 3 ;exit;
}
}my_handle_attachment（）：为一般单图上传返回附件id
2.文件下载参考
//文件下载
header("Content-type:text/html;charset=utf-8");
$file_name = $_REQUEST[‘file‘];
//用以解决中文不能显示出来的问题
$file_name=iconv("utf-8","gb2312",$file_name);
$file_sub_path=$_SERVER[‘DOCUMENT_ROOT‘].get_stylesheet_directory_uri();
$file_path=$file_sub_path.$file_name;
//首先要判断给定的文件存在与否
if(!file_exists($file_path)){
echo "没有该文件文件";
return ;
}
$fp=fopen($file_path,"r");
$file_size=filesize($file_path);
//下载文件需要用到的头
Header("Content-type: application/octet-stream");
Header("Accept-Ranges: bytes");
Header("Accept-Length:".$file_size);
Header("Content-Disposition: attachment; filename=".$file_name);
$buffer=1024;
$file_count=0;
//向浏览器返回数据
while(!feof($fp) && $file_count<$file_size){
$file_con=fread($fp,$buffer);
$file_count+=$buffer;
echo $file_con;
}
fclose($fp);
3.自定义分类查询
//自定义分类查询
$paged = 1;
if ( get_query_var(‘paged‘) ) $paged = get_query_var(‘paged‘);
if ( get_query_var(‘page‘) ) $paged = get_query_var(‘page‘);
$posts_per_page = get_option(‘posts_per_page‘);
$args = array(
‘post_type‘ => ‘post‘, //自定义文章类型
‘posts_per_page‘=> 2,
‘tax_query‘ => array(
array(
‘taxonomy‘ => ‘category‘, //调用自定义分类法
‘field‘ => ‘cat‘, //
‘terms‘ => $term_arr[‘term_id‘]
)
),
‘paged‘ => $paged
);
query_posts($args);
if (have_posts()) : while (have_posts()) : the_post();
wp_reset_query();
4.自定义字段筛选
$posts_per_pages = get_option(‘posts_per_page‘);
//$posts_per_pages = 1;
$paged = 1;
if ( get_query_var(‘paged‘) ) $paged = get_query_var(‘paged‘);
if ( get_query_var(‘page‘) ) $paged = get_query_var(‘page‘);
if(!empty($get_crowd) || !empty($get_xueke) || !empty($get_field) || !empty($get_app) ){
if(!empty($get_crowd)){
$crowd_array = array(
‘taxonomy‘ => ‘cat_crowd‘,
‘field‘ => ‘term_id‘,
‘terms‘ => $get_crowd
);
}
if(!empty($get_xueke)){
$xueke_array = array(
‘taxonomy‘ => ‘cat_xueke‘,
‘field‘ => ‘term_id‘,
‘terms‘ => $get_xueke
);
}
if(!empty($get_field)){
$field_array = array(
‘taxonomy‘ => ‘cat_field‘,
‘field‘ => ‘term_id‘,
‘terms‘ => $get_field
);
}
if(!empty($get_app)){
$app_array = array(
‘taxonomy‘ => ‘cat_application‘,
‘field‘ => ‘term_id‘,
‘terms‘ => $get_app
);
}
$args = array(
‘posts_per_page‘ => $posts_per_pages,
‘orderby‘ => $order,
‘order‘ => ‘desc‘,
‘post_type‘ => ‘type_product‘,
‘paged‘ => $paged,
‘post_status‘ => ‘publish‘,
‘tax_query‘ => array(
‘relation‘ => ‘AND‘,
$crowd_array,
$xueke_array,
$field_array,
$app_array,
)
);
}else{
$args = array(
‘post_type‘ => ‘type_product‘, //自定义文章类型
‘orderby‘ => $order,
‘order‘ => ‘desc‘,
‘posts_per_page‘ => $posts_per_pages,
‘paged‘ => $paged
);
}
query_posts($args); if (have_posts()) : ?><?php while (have_posts()) : the_post();
<?php endwhile;?>
<?php else: ?>
<div class="rock_list">
<p class="n_center"><?php _e(‘未找到内容‘,‘kepress‘); ?></p>
</div>
<?php endif; ?>
</ul>
<div class="page_wrap">
<?php of_pagenavi(999); ?>
</div>
<?php wp_reset_query(); ?>
5.loop 分页参考

6.手机端访问跳转
$agent = $_SERVER[‘HTTP_USER_AGENT‘];
if(strpos($agent,"comFront") || strpos($agent,"iPhone") || strpos($agent,"MIDP-2.0") || strpos($agent,"Opera Mini") || strpos($agent,"UCWEB") || strpos($agent,"Android") || strpos($agent,"Windows CE") || strpos($agent,"SymbianOS"))
header("Location:http://likinming.com/m/");
exit;/*(使用 header(location) 就跳转到另一个页面了，但事实上，PHP却仍然会执行后台的代码的)
7.ip
function ip()
{
if(getenv(‘HTTP_CLIENT_IP‘) && strcasecmp(getenv(‘HTTP_CLIENT_IP‘), ‘unknown‘))
{
$ip = getenv(‘HTTP_CLIENT_IP‘);
}
elseif(getenv(‘HTTP_X_FORWARDED_FOR‘) && strcasecmp(getenv(‘HTTP_X_FORWARDED_FOR‘), ‘unknown‘))

}
return preg_match("/[\d\.]{7,15}/", $ip, $matches) ? $matches[0] : ‘unknown‘;
}
