问题描述
我将dropzone与CI配合使用,上传不正确时我不知道如何显示错误消息和自定义消息,这是我的脚本
I use dropzone with CI, i don't know how to display error message and custom message when upload false, this is my script
Dropzone.autoDiscover = false;
try {
var myDropzone = new Dropzone("#adminform" , {
paramName: "filename", // The name that will be used to transfer the file
maxFilesize: 0.5, // MB
url: window.location.href,
addRemoveLinks : true,
dictDefaultMessage :
'<span class="bigger-150 bolder"><i class="ace-icon fa fa-caret-right red"></i> Drop files</span> to upload \
<span class="smaller-80 grey">(or click)</span> <br /> \
<i class="upload-icon ace-icon fa fa-cloud-upload blue fa-3x"></i>',
dictResponseError: 'Error while uploading file!',
//change the previewTemplate to use Bootstrap progress bars
previewTemplate: "<div class=\"dz-preview dz-file-preview\">\n <div class=\"dz-details\">\n <div class=\"dz-filename\"><span data-dz-name></span></div>\n <div class=\"dz-size\" data-dz-size></div>\n <img data-dz-thumbnail />\n </div>\n <div class=\"progress progress-small progress-striped active\"><div class=\"progress-bar progress-bar-success\" data-dz-uploadprogress></div></div>\n <div class=\"dz-success-mark\"><span></span></div>\n <div class=\"dz-error-mark\"><span></span></div>\n <div class=\"dz-error-message\"><span data-dz-errormessage></span></div>\n</div>",
});
}
catch(e) {
alert('Dropzone does not support older browsers!');
}
PHP返回400:
$this->output->set_header("HTTP/1.0 400 Bad Request");
但是当我将鼠标悬停在图像上时,它显示为[object Object],但消息为:
But when i hover image it's display [object Object] but message is:
dictResponseError:'上传文件时出错!'
dictResponseError: 'Error while uploading file!'
推荐答案
对于有需要的人:
您可以使用echo从服务器返回响应消息。然后在js代码中添加错误事件处理程序
You can return a response message from the server using echo. Then in the js code add an error event handler
PHP
header("HTTP/1.0 400 Bad Request");
echo "Ups error message";
JS
this.on('error', function(file, response) {
$(file.previewElement).find('.dz-error-message').text(response);
});
