element-ui upload组件多文件上传的示例代码

之前有一篇写的如何同时传递form表单及upload组件文件,如果有多个upload文件该如何传递呢

上代码

html

<el-form ref="newform" :model="newform" :rules="rules">

<el-form-item prop="expName" label="">

<el-input v-model="newform.expName" placeholder="" style="width:75%">

</el-input>

</el-form-item>

<el-form-item prop="expSn" label="">

<el-input v-model="newform.expSn" placeholder="" style="width:75%">

</el-input>

</el-form-item>

<el-form-item label='' prop="groupName">

<el-select v-model="newform.groupName" placeholder="" style="width:75%" @change="newSelectGroup($event)">

<el-option

v-for="item in groupOptions"

:key="item.groupId"

:label="item.groupName"

:value="item.groupId">

</el-option>

</el-select>

</el-form-item>

<el-form-item label="" prop="subGroupName">

<el-select v-model="newform.subGroupName" placeholder="" style="width:75%" @change="newSelectSubGroup($event)">

<el-option

v-for="item in subGroupOptions"

:key="item.subGroupId"

:label="item.subGroupName"

:value="item.subGroupId">

</el-option>

</el-select>

</el-form-item>

<el-form-item label="" prop="expvmDifficulty">

<el-rate v-model="newform.expvmDifficulty" :max="5" style="line-height: 2;"></el-rate>

</el-form-item>

<el-form-item label="" prop="expvmInstruction">

<el-upload

class="upload-demo"

drag

ref="uploadhtml"

:action="upload_url"

:auto-upload="false"

:before-upload="newHtml"

accept=".html, .htm">

<div class="el-upload__text">将文件拖到此处,或<em>点击上传</em></div>

<div slot="tip" class="el-upload__tip">实验信息上传,只能传(.html/.htm)文件</div>

</el-upload>

</el-form-item>

<el-form-item label="" prop="expvmFiles">

<el-upload

class="upload-demo"

drag

ref="uploadfile"

:action="upload_url"

:auto-upload="false"

:before-upload="newFiles"

multiple>

<div class="el-upload__text">将文件拖到此处,或<em>点击上传</em></div>

<div slot="tip" class="el-upload__tip">实验信息附件上传,只能传(.file)文件</div>

</el-upload>

</el-form-item>

<el-form-item label="" prop="expvmVideo">

<el-upload

class="upload-demo"

drag

ref="uploadvideo"

:action="upload_url"

:auto-upload="false"

:before-upload="newVideo"

accept=".mp4">

<div class="el-upload__text">将文件拖到此处,或<em>点击上传</em></div>

<div slot="tip" class="el-upload__tip">实验视频上传,只能传(.mp4)文件</div>

</el-upload>

</el-form-item>

<el-form-item style="text-align:center">

<el-button type="primary" @click="newSubmitForm()" class="yes-btn">

确 定

</el-button>

<el-button @click="resetForm('newform')">

重 置

</el-button>

</el-form-item>

</el-form>

js

data () {

return {

    upload_url: 'aaa', // 随便填一个,但一定要有

   uploadForm: new FormData(), // 一个formdata

rules: {}, // 用到的规则

newform: {

expName: '',

groupName: '',

expSn: '',

subGroupName: '',

expvmDifficulty: 1

}

}

}

methods

newSubmitForm () {

this.$refs['newform'].validate((valid) => {

if (valid) {

this.uploadForm.append('expName', this.newform.expName)

this.uploadForm.append('expSn', this.newform.expSn)

this.uploadForm.append('groupId', this.newgroupId)

this.uploadForm.append('subGroupId', this.newsubgroupId)

this.uploadForm.append('expvmDifficulty', this.newform.expvmDifficulty)

newExp(this.uploadForm).then(res => {

if (res.code === 400) {

this.$message.error(res.error)

} else if (res.code === 200) {

this.$message.success('上传成功!')

}

})

this.$refs.uploadhtml.submit() // 提交时触发了before-upload函数

this.$refs.uploadfile.submit()

this.$refs.uploadvideo.submit()

} else {

console.log('error submit!!')

return false

}

})

},

newHtml (file) { // before-upload

this.uploadForm.append('html', file)

return false

},

newFiles (file) {

this.uploadForm.append('file[]', file)

return false

},

newVideo (file) {

this.uploadForm.append('video', file)

return false

}

newExp函数是作为一个前后端交互的函数

export function newExp (data) {

return axios({

method: 'post', // 方式一定是post

url: '你的后台接收函数路径',

timeout: 20000,

data: data // 参数需要是单一的formData形式

})

}

PHP代码,后台接收

public function newExp() {

$param = $this->request->post(); // 获取页面表单传值

$files = $this->request->file(); // 接收到的文件

}

注意

this.uploadForm.append('file[]', file)

这里是接收多文件一定要是数组形式的file[]
