React – useState property not updating

I’m having trouble with react useState hook. I’m trying to clean the state on a dialog close. But theres’s always one property that does not gets updated.

Buttons:

Create btn
<Button className={classes.dashboardPosts__newPost} onClick={handleClickOpen}>nuevo post</Button>
Edit btn
<TableCell className={classes.dashboardPosts__bodyCell}><CreateIcon onClick={(e) => { onClickEdit(e, post._id) }} /></TableCell>

—- Edit —-

Close btn
<Button className={classes.dashboardPosts__modalButtons} onClick={handleClose} color="primary">Cancelar</Button>

That button opens a dialog box which has a textfield:

<Button className={classes.dashboardPosts__modalButtons} type="submit" color="primary">{input._id ? "Editar" : "Crear"}</Button>

This is how the dialog box open and closes:

const handleClickOpen = () => {
  setOpen(true);
};

const handleClose = () => {
  setPreviewLink("")
  setFile("No se ha seleccionado ningún archivo")
  setInput({
      _id: "",
      p_title: "",
      p_body: "",
      p_mainImage: null,
      p_link: ""
  })
  setOpen(false);
};

This is the state:

const [input, setInput] = useState({
   _id: "",
   p_title: "",
   p_body: "",
   p_mainImage: null,
   p_link: ""
})

This is the edit button click:

const onClickEdit = (e, id) => {
   e.preventDefault()
   const p = postsList.filter((up) => {
       return up._id === id
   })
   setInput({
       ...input,
       p_body: p[0].p_body,
       p_title: p[0].p_title,
       _id: p[0]._id,
       p_mainImage: p[0].p_mainImage,
   })
   setPreviewLink(p[0].p_title.replace(titleRegex, '').split(" ").join("-").toLowerCase())
   setFile(p[0].p_mainImage.split("").splice(0, 40).join("") + "...")
   handleClickOpen(e)
 }

The expected functionality is that when I click the edit btn, the modal opens with the post details and when the modal is closed, clean input so whenever I click on new post button the form is clean. However the form only gets clean when I open the modal with the new post button and then close it, not when I open it with the edit button. Everything gets cleaned but the p_title property.

So the problem was in my input onChange function, this is it:

const onInputChange = (e, name, data = "") => {
        e.preventDefault()
        setInput({ ...input, [name]: data !== "" ? data : e.target.value })
        if (name === "p_title") setPreviewLink(e.target.value.replace(titleRegex, '').split(" ").join("-").toLowerCase())
        if (name === "p_approved") {
            setInput({ ...input, [name]: !input.p_approved })
            return
        }
    }

However I don’t know how to solve it. My guess is that when the editor (CKeditor) input changes, it sets p_title to it’s original value.

I managed to solve it. What was happening is that whenever I updated the input state, the ckeditor component detected change so it changed the input state to the one that I set before closing the dialog box.

The solution was to create a diferent function to update ckeditor state, so the whole state doesn’t change when ckeditor updates.

This was the new function to update ckeditor state

const onEditorChange = (e, editor) => {
    setCkeditor(editor.getData())
}
