Question

下面的代码逐个上传图片。我想上传多张图片！

    <?php
//config
        require("./configuration.php");

            $id = $_GET['id'];
            $q = mysql_query("SELECT * FROM books WHERE id='$id'") or die(mysql_error());
            $row = mysql_fetch_array($q);
            $name = $row['name'];
            echo '<div class="center-top"> NAME: <strong style="font-size:22px;">'.$name.'</strong>  </div>';
        //begin upload
        if(isset($_POST['submit'])) 
        {

            $title = htmlspecialchars($_POST['title']);
                $path = "./upload/images/";
                $name_pic = $_FILES['file']['name'];
                $ext = strtolower(substr(strrchr($name_pic, "."), 1));
                $allow = array("jpg", "jpeg", "JPG", "JPEG", "png", "gif");
               $uptype = ($_FILES['file']['tmp_name']);
                if (in_array($ext, $allow))
                {
                       $rand = rand(0,10000);
                       $md5  = md5($rand);
                       $new_file_name = "{$md5}.{$ext}";
                       $move_file = move_uploaded_file($_FILES['file']['tmp_name'], $path.$new_file_name);
                       if($move_file) {
                            mysql_query("INSERT INTO images (id, link, title, bid)
                            VALUES (NULL, '$new_file_name', '$title', '$id')") or die (mysql_error());
                            echo "<div class='yes'>succesfully added!</div>";   
        }}}

        //form
        echo '
        <form method="post" action="images.php?id='.$id.'"  enctype="multipart/form-data"> 
        <br />title: <br /><input type="text" name="title" value="'.$name.'"/><br />
        <br /><br/><input name="file" type="file" />
        <br /><input type="submit" name="submit" value="UPLOAD" /><br /><br />
        </form> 
        ';
        ?>

使用此代码删除图像：

<?php
$id = $_GET['id']; 
$result = mysql_query("DELETE FROM imagesWHERE `id`='$id'");
echo "<div class='yes'>successfully deleted picture!</div>";
?>

首先，您需要将<input name="file" type="file"/>声明为<input name="file[]" type="file" multiple/> 然后，找到所选图像的总数。将其放入for loop并开始存储在 upload-＆gt; images 文件夹中，并将图片路径保存在images列中。

<?php

//config
require("./configuration.php");

$id = $_GET['id'];
$q = mysql_query("SELECT * FROM books WHERE id='$id'") or die(mysql_error());
$row = mysql_fetch_array($q);
$name = $row['name'];
echo '<div class="center-top"> NAME: <strong style="font-size:22px;">'.$name.'</strong>  </div>';
if(isset($_POST['submit'])) 
{
    $title = htmlspecialchars($_POST['title']);
    $path = "./upload/images/";
    $TotalImage = count($_FILES['file']['name']);
    for($i=0;$i>$TotalImage;$i++)
    { 

        $image_name = $_FILES['file']['name'][$i];
        $new_file_name = $path.$image_name;
        if(move_uploaded_file($_FILES['file']['tmp_name'][$i],$path.$image_name))
        {
            mysql_query("INSERT INTO images (id, link, title, bid) VALUES (NULL, '$new_file_name', '$title', '$id')") or die (mysql_error());
            echo "<div class='yes'>succesfully added!</div>";   
        }
    }
}

//form
echo '
<form method="post" action="images.php?id='.$id.'"  enctype="multipart/form-data"> 
<br />title: <br /><input type="text" name="title" value="'.$name.'"/><br />
<br /><br/><input name="file[]" type="file" multiple/>
<br /><input type="submit" name="submit" value="UPLOAD" /><br /><br />
</form> 
';
?>
