MDBFileInput

Marion Koosinlin asked 3 years ago

Hi MDB staff,

I registred as a free a user but in fact my boss bought the MDB pro licence so I am working with it now and I have a problem with the MDBFileInput component.

First, I have this code for uploading a file with a simple input which is working :

const initState = {
selectedFile: null,
}

class FormTeacher extends React.Component {
  constructor(props) {
    super(props);
      this.state = initState;
  }

onChangeHandleFile = (evt) => {

   this.setState({
      selectedFile: evt.target.files[0],
    });
  }

onClickHandleFile = () => {
    if(this.state.selectedFile !== null){
    const data = new FormData()
    data.append('file', this.state.selectedFile)
    axios.post("some API", data, {})
    .then(res => {
      console.log("Upload");
    })
    console.log(this.state.selectedFile);
    }
}

render() {
    return (
      <MDBContainer>
        <MDBRow>
          <MDBCol>
            <MDBCard>
              <MDBCardBody>
                  <form
                    className="needs-validation"
                    onSubmit={this.submitHandler}
                    noValidate
                  >
…
    <MDBRow>
                      <input type="file" name="file"
                      className='file' id="uploadedFile" onChange={this.onChangeHandleFile}/>
    </MDBRow>
    </form>
    </MDBCardBody>
              {this.state.isClicked === true ? (<DisplayQuizz evalStatus= {evalStatus} selectTest={selectTest} cancelForm={this.cancelForm} formData ={this.state} hideDisplayQuizz={this.hideDisplayQuizz} uploadFile={this.onClickHandleFile}/>) : ""}

            </MDBCard>
          </MDBCol>
        </MDBRow>
      </MDBContainer>
    );
}

But when I want to do the same thing with MDBInputfile and the getValue method, I have this error : enter image description here

And I don’t understand why it is not working although it works with a basic input. I searched on your website about MDBInputFile but did not find much information. I would be very glad if someone could explain me how I can make work this component.

I am looking forward from hearing from you.

Best regards,

Marion

Hi,

getValue method returns input value, on onChange event.

If you want to keep fileInput's value in your state you can try the next approach:

1)

onChangeHandleFile = files => {
    this.setState({
      selectedFile: files
    });
  };

2) <MDBFileInput getValue={this.onChangeHandleFile} />

Hope I helped you,

Best regards.


Thank you very much for your answer.
