之前有一篇寫的如何同時傳遞form表單及upload組件文件，如果有多個upload文件該如何傳遞呢
上代碼
html
<el-form ref="newform" :model="newform" :rules="rules">
<el-form-item prop="expName" label="">
<el-input v-model="newform.expName" placeholder="" >
</el-input>
</el-form-item>
<el-form-item prop="expSn" label="">
<el-input v-model="newform.expSn" placeholder="" >
</el-input>
</el-form-item>
<el-form-item label='' prop="groupName">
<el-select v-model="newform.groupName" placeholder="" @change="newSelectGroup($event)">
<el-option
v-for="item in groupOptions"
:key="item.groupId"
:label="item.groupName"
:value="item.groupId">
</el-option>
</el-select>
</el-form-item>
<el-form-item label="" prop="subGroupName">
<el-select v-model="newform.subGroupName" placeholder="" @change="newSelectSubGroup($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" ></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">將文件拖到此處，或<em>點擊上傳</em></div>
<div slot="tip" class="el-upload__tip">實驗信息上傳，只能傳(.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">將文件拖到此處，或<em>點擊上傳</em></div>
<div slot="tip" class="el-upload__tip">實驗信息附件上傳，只能傳(.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">將文件拖到此處，或<em>點擊上傳</em></div>
<div slot="tip" class="el-upload__tip">實驗視頻上傳，只能傳(.mp4)文件</div>
</el-upload>
</el-form-item>
<el-form-item >
<el-button type="primary" @click="newSubmitForm()" class="yes-btn">
確 定
</el-button>
<el-button @click="resetForm('newform')">
重 置
</el-button>
</el-form-item>
</el-form>
js
data () {
return {
upload_url: 'aaa', // 隨便填一個，但一定要有
uploadForm: new FormData(), // 一個formdata
rules: {}, // 用到的規則
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.$message.success('上傳成功！')
}
})
this.$refs.uploadhtml.submit() // 提交時觸發了before-upload函數
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函數是作為一個前后端交互的函數
export function newExp (data) {
return axios({
method: 'post', // 方式一定是post
url: '你的后臺接收函數路徑',
timeout: 20000,
data: data // 參數需要是單一的formData形式
})
}
PHP代碼，后臺接收
public function newExp() {
$param = $this->request->post(); // 獲取頁面表單傳值
$files = $this->request->file(); // 接收到的文件
}
注意
this.uploadForm.append('file[]', file)
這里是接收多文件一定要是數組形式的file[]
