图片上传无法在代码管理器中使用 [英] Image upload not working in codeignitor

问题描述

我创建图片上传代码。这首先创建目录，然后将图像上传到它。

I create image upload code. this create directory first and then upload images to it.

在表单上传3张图片。

我的代码是：

$dir_path = 'assets/images/product_images/'.$model;
mkdir($dir_path, 0777);

$i = 1 ;

    foreach ($image as $new_image)
        {
            $dir_path_up = 'assets/images/product_images/'.$model."/";
            $filename = $_FILES["$new_image"]["name"];
            $image_name  = $dir_path_up .$filename . $i. ".jpg";
                echo $image_name;

                $i++;
        }
        die();

echo

assets/images/product_images/255_2555/1.jpg
assets/images/product_images/255_2555/2.jpg
assets/images/product_images/255_2555/3.jpg

但是这些图片没有上传到目录。我回应我创建的图像名称。它的alredy改名。

But that images are not getting uploade in to directory. I echo the image name which i created. Its alredy renamed. Then why images not getting uploade into directory.

推荐答案

为什么图片不能上传到目录

解决方案

使用多图片上传可以很好地完成

<?php
    $j = 0;     // Variable for indexing uploaded image.
    $target_path = 'assets/images/product_images/' . $last_id . '/';     // Declaring Path for uploaded images.
    for ( $i = 0; $i < count($_FILES['image']['name']); $i++ )
    {
        // Loop to get individual element from the array
        $validextensions = array("jpeg", "jpg", "png");      // Extensions which are allowed.
        $ext = explode('.', basename($_FILES['image']['name'][$i]));   // Explode file name from dot(.)
        $file_extension = end($ext); // Store extensions in the variable.
        $target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext) - 1];     // Set the target path with a new name of image.
        $j = $j + 1;      // Increment the number of uploaded images according to the files in array.
        if ( ($_FILES["image"]["size"][$i] < 100000000)     // Approx. 100kb files can be uploaded.
            && in_array($file_extension, $validextensions)
        )
        {
            move_uploaded_file($_FILES['image']['tmp_name'][$i], $target_path);
        }
        else
        {

        }
    }
