Fussionweb · 技术社区 · 7 年前

上载时出错 multipart/form-data 表格,我有两个输入得到一个图像和pdf。

<form class="form-group" id="form-add" >

    <input name="title" size="30" class="form-control margin-bottom-25" id="title"  placeholder="Enter Title" spellcheck="true" autocomplete="off" type="text" />
    <input name="code" size="30" class="form-control margin-bottom-25" id="code"  placeholder="Enter Course Code" spellcheck="true" autocomplete="off" type="text" />
    <div class="wp-media-buttons"><input type="file" id="image_select" name="image" class="form-control margin-bottom-50" ></div>
    <div class="wp-media-buttons"><input type="file" name="pdf" id="pdf_select" class="form-control margin-bottom-50" ></div>
    <div class="col-md-6"><input type="text" id="batch" name="batch" class="form-control margin-bottom-25" placeholder="Enter Batch Size" /></div>
    <div class="margin-bottom-25 col-md-6"><select id="batch-dec" name="batch-dec" class="form-control margin-bottom-25">

    </select></div>

    <div class=" col-md-6">

    <div class="col-md-6">
    <select id="duration-dec" name="duration-dec-dec" class="form-control margin-bottom-25">
    <option >Select</option>
    <option value="Time Duration">Time Duration</option>
    <option value="Class Room">Field Work</option>
    </select>
    </div>
    <div class="clearfix"></div>
    <div class="margin-bottom-25">Add Course Description Below</div>
    <div id="editor-container" class="editor-container margin-bottom-25" style="position:relative">

    <textarea spellcheck="true" class="editor-area form-control margin-bottom-25" style="height: 326px; margin-top: 37px;" cols="40" name="content" id="content" aria-hidden="false"></textarea>
    </div>

      <input class="btn btn-primary publish" type="submit" name="submit" id="publish" value="Publish" /> 
</form>

Ajax代码

$(document).ready(function(){  

    $(document).on('click', '#publish', function(){  

       /*var code = $('#code').val();  
       var title= $('#title').val();  
       var image= $('#image_select').files[0]; 
       var pdf= $('#pdf_select').files[0];
       var batch = $('#batch').val();  
       var batch_dec = $('#batch-dec').val();  
       var duration = $('#duration').val();  
       var duration_dec = $('#duration-dec').val();  
       var content = $('#content').val();  
        if($(document).on('click','#draft')){
            var status = $('#draft').val();
        }
        else if(($(document).on('click','#publish'))){
            var status =$('#publish').val();
        } 
        var status =$('#publish').val();

        var formdata = new FormData();
        formdata.append('code',code);
        formdata.append('title',title);
        formdata.append('image',image);
        formdata.append('pdf',pdf);
        formdata.append('batch',batch);
        formdata.append('batch_dec',batch_dec);
        formdata.append('duration',duration);
        formdata.append('duration_dec',duration_dec);
        formdata.append('content',content);
        formdata.append('status',status);*/
        //alert(formdata);
        var formdata = new FormData($('#form-add')[0]);
        formdata.append('image',$('#image_select')[0].files[0] );
        formdata.append('pdf',$('#pdf_select')[0].files[0]);
        $.ajax({  
            url:"include/courses-add.php",  
           // method:"POST", 
            type:'post',            
            enctype:'multipart/form-data',
            data:formdata, 
            contentType:false,
            cache:false,
            processData: false,  

            success:function(data){  
                alert(data);
                $('#result').html("<div class='alert alert-success'>"+data+"</div>");
            } ,
            error:function(e)
            {
                console.log('error:',e);
            }
        });  
    });  

});

错误:

可见在JavaScript中尝试了很多代码还是它给出了错误,帖子只是提交而已

ajax块不工作,它在控制台中抛出了一个错误。
