How to insert an array of data into the database using PHP? - php

Question

I am getting the array value like below
Array
(
[0] => Array
(
[upload_label] => label 1
[upload_name] => 100-best_1940225136.png
[society_id] => 57
)
[1] => Array
(
[upload_label] => label 2
[upload_name] => 150x150_2147441709.png
[s_id] => 57
)
)
Now I have to insert the data into the database. So I used below inert code
$sqlUpload="INSERT INTO `tbl_uploadAll`(upload_label,upload_name,s_id) VALUES (:upload_label,:upload_name,:s_id)";
$stmt= $pdo->prepare($sqlUpload);
$stmt->execute($dataupload);
when I hit the button then am getting 500 error in the network tab
My full code here
if (isset($_POST['send'])) {
$total = count($_FILES['docUpload']['name']);
$dataupload=array();
for($i=0; $i < $total; $i++) {
if(isset($_FILES['docUpload']['name'][$i]) && $_FILES['docUpload']['name'][$i] != "")
{
$foldername="profile";
$uploadLabel=$_POST['docUploadLabel'][$i];
$image1 = $_FILES['docUpload']['name'][$i];
$filename = basename($image1);
$onlyfile = pathinfo($filename, PATHINFO_FILENAME);
$extension = pathinfo($filename, PATHINFO_EXTENSION);
$file = mt_rand();// random number
$newname = $onlyfile.'_'.$file.'.'.$extension;
//$location='images/'.$foldername.'/'.$newname;
$location='../assets/images/uploads/'.$foldername.'/'.$newname;
if($extension=='png' || $extension=='jpg' || $extension=='jpeg') {
compressImage($_FILES['docUpload']['tmp_name'][$i],$location,60);
}
else{
move_uploaded_file($_FILES['docUpload']['tmp_name'][$i], $location);
}
$uploadDoc=$newname;
$dataupload[]=array(
'upload_label'=>$uploadLabel,
'upload_name'=>$uploadDoc,
's_id'=>$last_id,
);
}
}
echo"<pre>";
print_r($dataupload);
$sqlUpload="INSERT INTO `tbl_uploadAll`(upload_label,upload_name,s_id) VALUES (:upload_label,:upload_name,:s_id)";
$stmt= $pdo->prepare($sqlUpload);
$stmt->execute($dataupload);
}

Answer 1

You are passing array of array
$stmt->execute($dataupload);
execute expects an array of key => value where key should be named placeholders. Like
$data = [
'name' => $name,
'surname' => $surname,
'sex' => $sex,
];
So for your case, you should execute inside a foreach
foreach ($dataupload as $row)
{
$stmt->execute($row);
}
