upload billede til mysql database php

Her er et script, jeg har ændret til at fungere med din tabelstruktur.

function addImageToDB($imageArray, $title = '', $subject = '', $visible = 0) {

$allowedExts = array("gif","jpeg","jpg","JPG","png","PNG");
$extension = end(explode(".", $imageArray["name"]));

if (
    (($imageArray["type"] == "image/gif") // is image type acceptable?
        || ($imageArray["type"] == "image/jpeg")
        || ($imageArray["type"] == "image/jpg")
        || ($imageArray["type"] == "image/png")
    )
    && ($imageArray["size"] < 1048576) // set maximum image size
    && in_array($extension, $allowedExts) // is image file extension in $allowedExts?
) {

    if ($imageArray["error"] > 0) { // check uploaded image for errors
        echo $imageArray['error'];
    } else {

        $tempImage = $imageArray['tmp_name'];
        $fp = fopen($tempImage, 'r');
        $image = fread($fp, filesize($tempImage));
        $image = addslashes($image);
        fclose($fp);

        $queryAddImageToDB = "INSERT INTO image (
            title,
            subject,
            image,
            visible
        ) VALUES (
            '$title'
            '$subject',
            '$image',
            '$visible'
        )";

        mysql_query ($queryAddImageToDB) or die ('queryAddImageToDB failed');
        $imageID = mysql_insert_id();

        return $imageID;

    }
} else {

    echo 'IMAGE UPLOAD ERROR: The image ie either too large or the file format is unacceptable.';

    echo '<pre>';
        print_r($imageArray); // display image array for debugging
    echo '</pre>';

}

}

Du kan kalde funktionen sådan her:

$imageArray = $_FILES['image'];
$title = $_POST['title'];
$subject = $_POST['subject'];
$visible = 1;
addImageToDB($imageArray, $title, $subject, $visible);

Bemærk venligst, at dette script IKKE ER KOMPLETT, da det kræver korrekt validering, escape osv.

Held og lykke, jeg håber, det løser sig for dig, og jeg ser frem til at høre feedback ellers.
