如果我不使用，如何包含 enctype=&quot;multipart/form-data&quot;<form> 标签上传文件到数据库？

Question

I want to upload pdf file to my database. On skimming through various resources I found that we have to include attribute enctype="multipart/form-data" in form tag. Problem is am not using form to fill data (coz of CSS designing and framework). form data is submitted by onClick function.

So how can I still upload file? I think we cant include enctype attribute in tag?

You can simple do this by this jQuery function

function uploadFile(blobFile) {
    var fd = new FormData();
    fd.append("fileToUpload", blobFile);

    $.ajax({
       url: "upload.php",
       type: "POST",
       data: fd,
       processData: false,
       contentType: false,
       success: function(response) {
           // .. do something
       },
       error: function(jqXHR, textStatus, errorMessage) {
           console.log(errorMessage); // Optional
       }
    });
} 

Usage

For this input

<input type="file" id="filechooser">

Use this

uploadFile($('#filechooser')[0].files[0]);
