“领带”上传图像到其余[关闭]

Question

I have a form and the person who fill it has the option to upload an image. The information is then stored in a table, with the person's name, e-mail, etc. and later shown in a page for the admin. I'm able to pull all the information, except I don't know how to store the image into the database and show it for the admin later. Hope you guys could understand

Answer 1

You don't store the images in the database, you store there path as a string

There is global variable called $_FILES just as $_GET and $_POST that contains all the info on the files uploaded. These are first stored in a temp directory. You use move_uploaded_files function to move them to a proper place. Then save the string in database.

<?php
$uploads_dir = '/uploads'; // Directory where you want to upload/keep all your pictures
// Lets assume you sent the picture in `pictures` name field of form
foreach ($_FILES["pictures"]["error"] as $key => $error) {
    if ($error == UPLOAD_ERR_OK) {
        $tmp_name = $_FILES["pictures"]["tmp_name"][$key];
        $name = $_FILES["pictures"]["name"][$key];
        move_uploaded_file($tmp_name, "$uploads_dir/$name");
       // Save `$upload_dir/$name` in db
    }
}
?>

Now when you want to load the image later, just query the column of the table that stores the images location and use it as src at frontend.
