React native upload image to php












0















I'm trying to save an image returned from react-native-view-shot which looks something like this (file:///data/user/ReactNative-snapshot-image123.png) but I don't know why the image is not saved on my server.
This is what I've done.



       savePicture = () =>{
this.refs.viewShot.capture().then(uri => {
this.setState(
{
imageURI:uri
});

var data = new FormData();
data.append('image', {
uri: this.state.imageURI,
name: 'my_photo.png',
type: 'image/png'
});
fetch('http://www.url.com/upload.php', {
headers: {
'Accept': 'application/json',
'Content-Type': 'multipart/form-data'
},
method: 'POST',
body: JSON.stringify({
image: data
})
})
.then((response) => response.json())
.then((responseData) => {console.warn(responseData);})
.catch((error) => {
console.warn(error);
})
.done();
});
}


and here is my php to save the image on my server.



<?
header("Access-Control-Allow-Origin: *"); header("Access-Control-Allow-Headers: *");
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$shuffledid = str_shuffle(124243543534543534);
$url = $shuffledid;
$path = $_SERVER['DOCUMENT_ROOT'].'/android';

$json = json_decode(file_get_contents('php://input'), true);
$img = $json['image'];
list($width,$height,$type) = getimagesize($img);
switch(strtolower(image_type_to_mime_type($type)))
{
case 'image/gif':
$pic = imagecreatefromgif($img);
break;
case 'image/png':
$pic = imagecreatefrompng($img);
break;
case 'image/jpeg':
$pic = imagecreatefromjpeg($img);
break;
default:
return false;
break;
}

$bg = imagecreatetruecolor(600,700);
imagecopyresampled($bg,$img,0,0,0,0,600,700,$width,$height);
imagepng($bg, $path.'/'.$url.'.png');
imagedestroy($img);

echo "done";
}
?>


My PHP just returns this error:




getimagesize() expects parameter 1 to be string, array given




I tried with var_dump($_POST) to see what is returned but I got something like this



{line:21352",column:16,sourceUrl:http.../index.delta?platform=android$dev=true...


Do you have any idea what I'm not doing right?
I've also did



body: data


on my react fetch without json.stringify but still nothing.



Thank you!



Solved! If someone needs this



const formData = new FormData();
formData.append('image', {
uri: this.state.imageURI,
name: 'my_photo.png',
type: 'image/png'
});
formData.append('Content-Type', 'image/png');

fetch('http://www.url.com/upload.php',{
method: 'POST',
headers: {
'Content-Type': 'multipart/form-data',
},
body: formData
})
.then((response) => response.json())
.then((responseJson) => {
console.log(responseJson);
})
.catch((error) => {
console.log(error);
});
});


PHP



$img = $_FILES['image']['tmp_name'];
$shuffledid = str_shuffle(124243543534543534);
$url = $shuffledid;
$path = $_SERVER['DOCUMENT_ROOT'].'/android';
list($width,$height,$type) = getimagesize($img);
$pic = imagecreatefrompng($img);
$bg = imagecreatetruecolor(600,700);
imagecopyresampled($bg,$pic,0,0,0,0,600,700,$width,$height);
imagepng($bg, $path.'/'.$url.'.png');
imagedestroy($pic);
echo json_encode("done");

  • Look at the JSON you're building on the client side, and then look at what you're trying to extract from it on the server side. They do not match. I don't know react, but it doesn't look like you're sending an image at all.

  • this.state.imageURI is the image saved on the device cache.

  • Regardless, you have to get to it first, by making sure your PHP knows the correct format of your JSON, which it does not at the moment.
