Hi @koop_g. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To create a form with image upload using Material UI in refine, you can use the useForm hook from @refinedev/react-hook-form along with Material UI components. Here's an example of how you can implement this:
import { useState } from "react";
import axios from "axios";
import { Edit } from "@refinedev/mui";
import { Box, Input, Stack, Typography } from "@mui/material";
import { LoadingButton } from "@mui/lab";
import { HttpError } from "@refinedev/core";
import { useForm } from "@refinedev/react-hook-form";
import FileUploadIcon from "@mui/icons-material/FileUpload";

import { ICategory, IPost } from "interfaces";

import { TOKEN_KEY, API_URL } from "../../constants";

export const PostEdit: React.FC = () => {
const [isUploadLoading, setIsUploadLoading] = useState(false);
const [imageURL, setImageURL] = useState("");

const {
saveButtonProps,
register,
formState: { errors },
setValue,
setError,
} = useForm<IPost, HttpError, IPost & { category: ICategory; cover: any }>();

const onChangeHandler = async (
event: React.ChangeEvent<HTMLInputElement>,
) => {
try {
setIsUploadLoading(true);

const formData = new FormData();

const target = event.target;
const file: File = (target.files as FileList)[0];

formData.append("files", file);

const res = await axios.post(`${API_URL}/api/upload`, formData, {
headers: {
Authorization: `Bearer ${localStorage.getItem(TOKEN_KEY)}`,
},
});

setImageURL(`${API_URL}${res.data[0].url}`);
setValue("cover", res.data[0].id, { shouldValidate: true });

setIsUploadLoading(false);
} catch (error) {
setError("cover", { message: "Upload failed. Please try again." });
setIsUploadLoading(false);
}
};
return (

This example demonstrates how to create a form with image upload using Material UI components in refine. Here's a breakdown of the key elements: 1. The useForm hook from @refinedev/react-hook-form is used to manage the form state and validation. 2. Material UI components like Box, Input, Stack, Typography, and LoadingButton are used to create the form layout. 3. The onChangeHandler function handles the file upload process using axios to send the file to the server. 4. The uploaded image URL is stored in the state and displayed using the Box component as an image preview. 5. Error handling and validation are implemented using the formState and setError from the useForm hook. This example is based on the File Upload documentation for Strapi v4 in refine. You can adapt this example to fit your specific needs and backend API requirements. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how can I add body data to be sent with the file on the same API CALL
kapa.ai
kapa.ai2d ago
Let me check the knowledge base for you again. One moment! :books: ---------------------- To add body data to be sent along with the file in the same API call, you can modify the onChangeHandler function to include additional data in the FormData object. Here's how you can do it:
const onChangeHandler = async (
event: React.ChangeEvent<HTMLInputElement>,
) => {
try {
setIsUploadLoading(true);

const formData = new FormData();

const target = event.target;
const file: File = (target.files as FileList)[0];

formData.append("files", file);

// Add additional body data
formData.append("title", "Your title here");
formData.append("description", "Your description here");
// Add more fields as needed

const res = await axios.post(`${API_URL}/api/upload`, formData, {
headers: {
Authorization: `Bearer ${localStorage.getItem(TOKEN_KEY)}`,
"Content-Type": "multipart/form-data", // Ensure this header is set
},
});

setImageURL(`${API_URL}${res.data[0].url}`);
setValue("cover", res.data[0].id, { shouldValidate: true });

setIsUploadLoading(false);
} catch (error) {
setError("cover", { message: "Upload failed. Please try again." });
setIsUploadLoading(false);
}
};
const onChangeHandler = async (
event: React.ChangeEvent<HTMLInputElement>,
) => {
try {
setIsUploadLoading(true);

const formData = new FormData();

const target = event.target;
const file: File = (target.files as FileList)[0];

formData.append("files", file);

// Add additional body data
formData.append("title", "Your title here");
formData.append("description", "Your description here");
// Add more fields as needed

const res = await axios.post(`${API_URL}/api/upload`, formData, {
headers: {
Authorization: `Bearer ${localStorage.getItem(TOKEN_KEY)}`,
"Content-Type": "multipart/form-data", // Ensure this header is set
},
});

setImageURL(`${API_URL}${res.data[0].url}`);
setValue("cover", res.data[0].id, { shouldValidate: true });

setIsUploadLoading(false);
} catch (error) {
setError("cover", { message: "Upload failed. Please try again." });
setIsUploadLoading(false);
}
};
In this modified version, we're adding additional fields to the FormData object using the append method. You can add as many fields as you need, such as title, description, or any other data you want to send along with the file. If you want to send data from other form fields, you can access their values using the getValues method from the useForm hook. Here's an example of how you might do that:
const {
saveButtonProps,
register,
formState: { errors },
setValue,
setError,
getValues, // Add this
} = useForm<IPost, HttpError, IPost & { category: ICategory; cover: any }>();
const onChangeHandler = async (
event: React.ChangeEvent<HTMLInputElement>,
) => {
try {
setIsUploadLoading(true);

const formData = new FormData();

const target = event.target;
const file: File = (target.files as FileList)[0];

formData.append("files", file);

// Add data from other form fields
const { title, content, category } = getValues();
formData.append("title", title);
formData.append("content", content);
formData.append("category", category.id);

// ... rest of the function remains the same
} catch (error) {
// ... error handling
}
};
const {
saveButtonProps,
register,
formState: { errors },
setValue,
setError,
getValues, // Add this
} = useForm<IPost, HttpError, IPost & { category: ICategory; cover: any }>();
const onChangeHandler = async (
event: React.ChangeEvent<HTMLInputElement>,
) => {
try {
setIsUploadLoading(true);

const formData = new FormData();

const target = event.target;
const file: File = (target.files as FileList)[0];

formData.append("files", file);

// Add data from other form fields
const { title, content, category } = getValues();
formData.append("title", title);
formData.append("content", content);
formData.append("category", category.id);

// ... rest of the function remains the same
} catch (error) {
// ... error handling
}
};
This approach allows you to send both the file and additional form data in a single API call. Make sure your backend API is set up to handle this multipart form data correctly. File Upload documentation for Strapi v4 Remember to adjust the field names and types according to your specific form structure and API requirements. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai given the refine create template that is working for me , how can I add an image upload field for that request.POST here is a record example
"id": 46,
"name": "my attachment",
"image": "http://localhost/media/upload_to/orange.png",
"type": null,
"performance": 44,
"id": 46,
"name": "my attachment",
"image": "http://localhost/media/upload_to/orange.png",
"type": null,
"performance": 44,
here is the refine create example I am using of Metirial UI :
import { Create } from "@refinedev/mui";
import { Box, TextField } from "@mui/material";
import { useForm } from "@refinedev/react-hook-form";

export const MyCreate = () => {
const {
saveButtonProps,
refineCore: { formLoading },
register,
control,
formState: { errors },
} = useForm();

return (
<Create isLoading={formLoading} saveButtonProps={saveButtonProps}>
<Box
component="form"
sx={{ display: "flex", flexDirection: "column" }}
autoComplete="off"
>
// all my existing field goes here
<TextField/>........


</Box>
</Create>
);
};
import { Create } from "@refinedev/mui";
import { Box, TextField } from "@mui/material";
import { useForm } from "@refinedev/react-hook-form";

export const MyCreate = () => {
const {
saveButtonProps,
refineCore: { formLoading },
register,
control,
formState: { errors },
} = useForm();

return (
<Create isLoading={formLoading} saveButtonProps={saveButtonProps}>
<Box
component="form"
sx={{ display: "flex", flexDirection: "column" }}
autoComplete="off"
>
// all my existing field goes here
<TextField/>........


</Box>
</Create>

This modified version of your create form includes the following changes: 1. We've added a file input disguised as a Button for image upload. 2. The handleImageUpload function manages the image upload process. It sends the file to your API endpoint (${apiUrl}/media/upload) and sets the returned URL to both the state and the form value. 3. We've added a preview of the uploaded image. 4. The handleSubmit function is modified to include the image URL in the form data when submitting. Make sure to adjust the API endpoint (${apiUrl}/media/upload) to match your actual upload endpoint. Also, ensure that your backend is set up to handle file uploads and return the URL of the uploaded image. This implementation assumes that your API returns the image URL in the format you provided (<http://localhost/media/upload_to/orange.png>). If the response format is different, you may need to adjust the setValue call in the handleImageUpload function.

@kapa.ai my server doesn't have an "upload image" request API, it should be one request combined with the data. again, can you take the provided refine material UI "create" template checge it so it would support an additional filed so all data including image field would be sent togethter ?

Let me check the knowledge base for you again. One moment! :books: ---------------------- Certainly! I understand that your server expects a single request with both the image and other data combined. Let's modify the provided refine Material UI "create" template to support an additional image field that will be sent together with the rest of the data. Here's how you can adapt the template:
import { Create } from "@refinedev/mui";
import { Box, TextField, Button } from "@mui/material";
import { useForm } from "@refinedev/react-hook-form";

The handleImageSelect function manages the image selection process and sets the selected file in both the state and the form value. 3. We've modified the handleSubmit function to create a FormData object that includes all form fields, including the image file. 4. The onFinish function is now called with the FormData object, which will send all data including the image in a single request. This implementation allows you to send all the data, including the image, in a single request to your server. The server should be set up to handle multipart/form-data requests to process this combined data correctly. How to Multipart File Upload with Refine and React Hook Form? Remember to adjust your data provider or API client to handle sending FormData objects if necessary. Also, ensure that your backend is set up to receive and process multipart/form-data requests that include both file and text fields. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai the property name "data" that is provided at handleSubmit is an event and not a form data, how can we get the data out of the create form ?
kapa.ai
kapa.ai2d ago
Let me check the knowledge base for you again. One moment! :books: ---------------------- You're right, and I apologize for the confusion in my previous response. In refine's Material UI implementation with @refinedev/react-hook-form, the handleSubmit function indeed receives an event rather than form data directly. Let's correct this and show how to properly get the form data in the create form. Here's the corrected version of the MyCreate component, focusing on how to properly handle form submission and get the form data:
import { Create } from "@refinedev/mui";
import { Box, TextField, Button } from "@mui/material";
import { useForm } from "@refinedev/react-hook-form";
import { useState } from "react";

export const MyCreate = () => {
const [selectedFile, setSelectedFile] = useState<File | null>(null);

const {
saveButtonProps,
refineCore: { formLoading, onFinish },
register,
control,
formState: { errors },
setValue,
getValues,
} = useForm();

const handleImageSelect = (event: React.ChangeEvent<HTMLInputElement>) => {
const file = event.target.files?.[0];
if (file) {
setSelectedFile(file);
setValue("image", file);
}
};

const handleSubmit = async (e: React.FormEvent<HTMLFormElement>) => {
e.preventDefault();
const formData = new FormData();

// Get all form values
const values = getValues();

// Append all form fields to formData
Object.keys(values).forEach(key => {
if (key === "image" && selectedFile) {
formData.append("image", selectedFile);
} else {
formData.append(key, values[key]);
}
});

// Use onFinish to send the combined data
await onFinish(formData);
};
return (
<Create isLoading={formLoading} saveButtonProps={{
...saveButtonProps,
onClick: (e) => {
e.preventDefault();
handleSubmit(e as React.FormEvent<HTMLFormElement>);
},
}}>
<Box
component="form"
sx={{ display: "flex", flexDirection: "column" }}
autoComplete="off"

The key changes in this corrected version are: 1. We use the getValues() function from useForm to get all the form values. 2. The handleSubmit function now correctly receives an event of type React.FormEvent<HTMLFormElement>. 3. We prevent the default form submission behavior using e.preventDefault(). 4. We create a FormData object and populate it with the form values obtained from getValues(). 5. The saveButtonProps now uses an arrow function to call handleSubmit with the correct event type. This approach ensures that we correctly get all the form data, including the file input, and send it as a single FormData object to the server. React Hook Form Validation with Complete Examples Remember to adjust your data provider or API client to handle sending FormData objects if necessary, and ensure that your backend is set up to receive and process multipart/form-data requests. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
