1.创建url 链接到form
$items['qianfeng/add'] = array( 'title' => t('加入信息'), 'page callback' => 'drupal_get_form', 'page arguments' => array('qianfeng_add',1), 'file' => 'videocloud_qianfeng.pages.inc', 'access callback' => 'user_is_logged_in', 'weight' => -10, 'type' => MENU_CALLBACK, );
创建form元素
$barcode_image 为图片路径
function qianfeng_add($form, $form_state,$barcode_id){
if(!empty($barcode_image)){ $form['barcode_image_current'] = array( '#title' => t('图片'), '#prefix' => l('<img class="barcode_image" src='.$barcode_image.'>',$barcode_image , array("html" => true)), '#weight' => 3, ); } $form['barcode_image'] = array( '#type' => 'file', '#name'=>'barcode_image', '#required' => false, '#weight' =>4 ); $form['submit'] = array( '#title' => t('提交'), '#type' => 'submit', '#value'=>'提交', '#weight' =>5 ); $form['#attributes']['enctype'] = 'multipart/form-data'; return $form; }
form 提交函数
function qianfeng_add_submit($form, $form_state){
$tp = array("gif","jpg","png","bmp");$file = $_FILES["barcode_image"];
if(!empty($file['name'])){ $path = "./sites/default/files/barcode/"; if(!file_exists($path)){ mkdir($path,0777,true); } $name = md5(time().rand(1,10000)); $fname=$file['name']; $ftype=explode('.',$fname); $picName=$path.$name.'.'.$ftype[1]; if(!in_array($ftype[1], $tp)){ drupal_set_message("图片格式不对，正确的格式（gif,jpg,png,bmp）！",'warning'); return false; } if(intval($file['size'])>2097152){ drupal_set_message("图片大小超出2M,请上传2M下面的图片！",'warning'); return false; }$id = move_uploaded_file($file['tmp_name'],$picName);$fields['image_name'] = $name.'.'.$ftype[1]; $fields['image_path'] = "sites/default/files/barcode/";
} }
