最近研究個(gè)專(zhuān)案需要在wordpress前端上傳使用者頭像,在網(wǎng)路上查了些資料！解決了這個(gè)問(wèn)題！
1:首先就是在需要的地方新增檔案上傳框了
<form action="" method="post" enctype="multipart/form-data"> ????<input type="file" id="file" name="files[]" multiple="multiple" accept="image/*" /> ??<input type="submit" name="submit" value="Upload!" /> </form>
2: 對(duì)圖片進(jìn)行處理
$post=get_post(13);//測(cè)試用
if?(?$_FILES?)?{
????$files?=?$_FILES['files'];
?????$count=?count($files['name']);
????foreach?($files['name']?as?$key?=>?$value)?{
????????if?($files['name'][$key])?{
????????????$file?=?array(
????????????????'name'?????=>?$files['name'][$key],
????????????????'type'?????=>?$files['type'][$key],
????????????????'tmp_name'?=>?$files['tmp_name'][$key],
????????????????'error'????=>?$files['error'][$key],
????????????????'size'?????=>?$files['size'][$key]
????????????);
????????????$_FILES?=?array("files"?=>?$file);
????????????foreach?($_FILES?as?$file?=>?$array)?{
????????????????$newupload?=?insert_attachment($file,$post->ID);//此方法將文章附加到ID為13的文章中。如果不想插入到文章可以為空""
}?}?}?}
3:在functions.php檔案中新增功能函數(shù)
#insert_attachment該函數(shù)的第二個(gè)參數(shù)如果為空將不附加到文章中圖片。
function?insert_attachment($file_handler,$post_id,$setthumb='false')?{
?global?$wpdb;
??//?check?to?make?sure?its?a?successful?upload
??if?($_FILES[$file_handler]['error']?!==?UPLOAD_ERR_OK)?__return_false();
??require_once(ABSPATH?.?"wp-admin"?.?'/includes/image.php');
??require_once(ABSPATH?.?"wp-admin"?.?'/includes/file.php');
??require_once(ABSPATH?.?"wp-admin"?.?'/includes/media.php');
??$attach_id?=?media_handle_upload(?$file_handler,?$post_id?);
$image_url?=?wp_get_attachment_image_src(??$attach_id,'full'?);?
if?($setthumb){?
??$wpdb->insert(
??$wpdb->prefix?.?'postmeta',?array(
????????????????'post_id'?=>?$post_id,
????????????????'meta_key'?=>?'wpcf-vi-img',
????????????????'meta_value'?=>?$image_url[0]?));
??}
??return?$attach_id;
} 4:引用方法
$image_url?=?wp_get_attachment_image_src(??$attach_id,'full'?);//由于頁(yè)面刷新的問(wèn)題直接在頁(yè)面使用這個(gè)方法是不生效的！需要在函數(shù)中構(gòu)造此方法的功能。
//循環(huán)文章中的特征圖片的方法，如果將圖片附加到文章中使用這個(gè)方法可以批量輸出！
$imagess=get_post_meta(13,'wpcf-vi-img',false);
foreach($imagess?as?$images){
?echo??$images;
}
