第一步： 搭建上传类基础工作，具体请看：//www.jb51.net/article/120242.htm
第二步：建站一个product表，字段id,name,picurl.
第三步：生GII生成PRODUCT 模型，类，视图。
第四步：
main.css 放在frontend\web\css
.onedialog{position:absolute; left: 300px; top: 500px; z-index: 10; width: 700px; height: 400px;border-radius:5px;box-shadow:5px 2px 6px #000; border: 2px solid #666}
.oneiframe{ width: 100%; height: 100% }
main.js 放在 frontend\web\assets
$(function(){
$('#product-picurl').click(function(){
$('#oneupload').remove();
$('<div>').appendTo($('body')).attr({"class":"onedialog",'id':"oneupload"});
$('<iframe>').appendTo($('#oneupload')).attr({"src":"","class":"oneiframe"})
});
var v=$('#product-picurl').val();
if(v){
$('<img>').attr({"src":v,"style":"height:50px"}).insertAfter($('#product-picurl'));
}
});
然后在frontend\assets\AppAsset.php中注册这两个文件
class AppAsset extends AssetBundle
{
public $basePath = '@webroot';
public $baseUrl = '@web';
public $css = [
'css/site.css',
'css/main.css',
];
public $js = [
'assets/main.js'
];
public $depends = [
'yii\web\YiiAsset',
'yii\bootstrap\BootstrapAsset',
];
}
UploadController.php
<"YmdHis") . '.' . $model->file->extension;
$model->file->saveAs($fileName);
}
echo "<script src='assets/upload.js'></script>;";
echo "<script>";
echo "var oneinput=parent.document.getElementById('product-picurl');";
echo "parent.document.getElementById('product-picurl').value='".$fileName."';";
echo "var oneupload = parent.document.getElementById('oneupload');";
echo "var img = document.createElement('img');";
echo "img.setAttribute('style', 'height:50px');";
echo "img.src ='".$fileName."';";
echo "insertAfter(img,oneinput);";
echo "oneupload.parentNode.removeChild(oneupload)";
echo "</script>";
}
return $this->render('upload', ['model' => $model]);
}
}
"htmlcode">
<"htmlcode">
<?php
use yii\widgets\ActiveForm;
?>
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]) ?>
<?= $form->field($model, 'file')->fileInput() ?>
<button>Submit</button>
<?php ActiveForm::end() ?>
