如何在php中插入多个图像并移入文件夹？

Question

$(document).ready(function(){
    $("#add_small").click(function(event){
        event.preventDefault();
        $(".add_small").append('<div class="form-group">\
            <label for="product_small_image">Product Image:</label>\
            <input type="file" name="product_image[]" class="product_image" value=""/>\
            <a href="javascript:void(0)" class="remove_small">Remove</a>\
        <div>');
    });

    jQuery(document).on('click', '.remove_small', function() {
        jQuery(this).parent().remove();
        return false;
    });
});

This is my duplicate question. I have create add and remove more file using jQuery. Now, What happen when I click on add button it show me to choose another file similarly again and again. I am able to upload multiple file like this. But the problem is that when I click on submit button to insert into the database and move image to the folder it show me error i.e.

</div>

Answer 1

I found the reason in your code:

$banner_image_tmp = $_FILES['product_image']['tmp_name'];

The $banner_image_tmp will return an array. So, there will be an error

move_uploaded_file() expects parameter 1 to be string, array given

http://php.net/manual/en/features.file-upload.multiple.php. Your code should be:

if(isset($_POST['submit']))
{
    $file_ary = reArrayFiles($_FILES['product_image']);

    foreach ($file_ary as $file) {
        print 'File Name: ' . $file['name'];
        print 'File Type: ' . $file['type'];
        print 'File Size: ' . $file['size'];
        //Your custom code here

    }
}

function reArrayFiles(&$file_post) {

    $file_ary = array();
    $file_count = count($file_post['name']);
    $file_keys = array_keys($file_post);

    for ($i=0; $i<$file_count; $i++) {
        foreach ($file_keys as $key) {
            $file_ary[$i][$key] = $file_post[$key][$i];
        }
    }

    return $file_ary;
}
