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[]
