上传自定义水印图片到图片空间及保存数据库的方法

(1)、添加我的水印，按钮展示：

 <div class="form-actions">
        <button data-toggle="modal" class="sui-btn btn-primary btn-large" onclick="addmywatermark();" >添加我的水印</button>
     </div>
    /**
    * 添加我的水印
    **/
    function addmywatermark(){
        $("#bjtp").modal('show');
    }

（2）、按钮点击的上传图片

 /*
    * id="bjtp"，modal页面展示
    */
    <div id="bjtp" tabindex="-1" role="dialog" data-hasfoot="true" data-backdrop="static" class="sui-modal hide fade" data-width="500px" >
    <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
      <button type="button" data-dismiss="modal" aria-hidden="true" class="sui-close">×</button>
         <h4 id="myModalLabel" class="modal-title">添加我的水印模板</h4>
      </div>
     <div class="modal-body" >
     <form class="sui-form"  id="picfile" name="picfile" >
    <label class="control-label">上传图片 ：</label>
    <div class="controls">
        <span>
        <input type="hidden" id="user_nick" name="user_nick"/>
        <input type="file" id="file" name="file" style="display:none;" onchange="previewImageLogo(this);"/>
        <button type="button" class="sui-btn btn-primary" onclick="file.click()" value="">浏览本地图片</button>
        <div id="pic_logo"><img src="" width="100mm" id="logopic" height="100mm"/></div>
    </div><br/> 
    </form>
     </div>
      <div class="modal-footer">
         <button  data-ok="modal" data-toggle="modal"  data-keyboard="false" class="sui-btn btn-primary btn-lg" onclick="getpicspaceimages();">确定</button>
         <button type="button" data-dismiss="modal" class="sui-btn btn-default btn-large">关闭</button>
     </div>
    </div>
    </div>
  </div>

　（3）、浏览本地图片，确定上传按钮

function getpicspaceimages(){
    $("#user_nick").val(user_nick);
    var form = document.getElementById("picfile");/*form表单用于上传文件，ajax请求发送formData*/   
    var formData = new FormData(form);   
    console.log("formData:"+formData);
    $.ajax({    
        url: APP_WEB_INDEX_ROOT+'/itemdb2/uploadimgs',        
        type: 'POST',              
        data: formData,              
        cache: false,        
        contentType: false,        
        processData: false,
        dataType:'json',                
        beforeSend: function(data){ },      
        success: function(data){
            console.log(data);
            if(data=='fail'){
                layer.msg('上传图片失败！', 1, 3);
            }else{
                layer.msg('上传图片成功！', 2, 1);
                showownmarkimgs();/*提取数据库数据，运用dot模板展现所有的自定义水印模板*/
            }
        },       
        error: function(data){
            layer.msg('上传图片失败！', 1, 3);
        }   
    });
}

（4）、上传水印图片后台代码

function uploadimgsAction(){
    log_message("info",'进来了!');
    $nick = $_POST['user_nick'];
    if(empty($nick)){
        return 'fail';
    }
    $picture_category_id = $_POST['category_id'];
    $this->log("resp:".json_encode($nick));
  
    $scp = $_FILES['file'];
    $logo_name = $scp["tmp_name"];
    $this->log("scp:".$scp.",logo_name:".$logo_name);
    if ($_FILES["file"]["error"] > 0){
        $this->log_error('-','自定义水印上传图片空间','uploadimgsAction',"上传失败:文件出错");
        echo json_encode("fail");
    }else{
        $pinfo = pathinfo($_FILES["file"]["name"]);
        $photo_type = $pinfo['extension'];
        $pic_name = md5(microtime(true)).".".$photo_type;
        $pic_path = "/data/tmp/".$pic_name;  /*定义临时文件夹用于存放水印图片*/
        $this->log("pic_path:".$pic_path);

        if(!move_uploaded_file ($_FILES["file"]["tmp_name"], $pic_path)){
            /*
            *move_uploaded_file() 函数将上传的文件移动到新位置。
            *若成功，则返回 true，否则返回 false。
            *
            */

            echo json_encode("fail");
        }else{

                return 'fail';
