Come memorizzare le immagini nel database mysql utilizzando php

Question

Come posso archiviare e visualizzare le immagini in un database MySQL. Fino ad ora ho scritto solo il codice per ottenere le immagini da parte dell'utente e memorizzarli in una cartella, il codice che ho scritto fino ad ora è: file HTML

<input type="file" name="imageUpload" id="imageUpload"> 

PHP FILE

$target_dir = "uploads/"; 
$target_file = $target_dir . basename($_FILES["imageUpload"]["name"]); 
$uploadOk = 1; 
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); 


if (move_uploaded_file($_FILES["imageUpload"]["tmp_name"], $target_file)) { 
    echo "The file ". basename($_FILES["imageUpload"]["name"]). " has been uploaded."; 
} else { 
    echo "Sorry, there was an error uploading your file.";} 

Answer 1

Ho trovato la risposta, Per quelli che cercano la stessa cosa ecco come l'ho fatto. Non dovresti considerare di caricare immagini nel database, ma puoi memorizzare il nome del file caricato nel tuo database e poi recuperare il nome del file e usarlo dove vuoi che venga visualizzata l'immagine.

CODICE HTML

<input type="file" name="imageUpload" id="imageUpload"> 

PHP CODICE

if(isset($_POST['submit'])) { 

    //Process the image that is uploaded by the user 

    $target_dir = "uploads/"; 
    $target_file = $target_dir . basename($_FILES["imageUpload"]["name"]); 
    $uploadOk = 1; 
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); 

    if (move_uploaded_file($_FILES["imageUpload"]["tmp_name"], $target_file)) { 
     echo "The file ". basename($_FILES["imageUpload"]["name"]). " has been uploaded."; 
    } else { 
     echo "Sorry, there was an error uploading your file."; 
    } 

    $image=basename($_FILES["imageUpload"]["name"],".jpg"); // used to store the filename in a variable 

    //storind the data in your database 
    $query= "INSERT INTO items VALUES ('$id','$title','$description','$price','$value','$contact','$image')"; 
    mysql_query($query); 

    require('heading.php'); 
    echo "Your add has been submited, you will be redirected to your account page in 3 seconds...."; 
    header("Refresh:3; url=account.php", true, 303); 
} 

CODICE per visualizzare l'immagine

while($row = mysql_fetch_row($result)) { 
    echo "<tr>"; 
    echo "<td><img src='uploads/$row[6].jpg' height='150px' width='300px'></td>"; 
    echo "</tr>\n"; 
}
