javascript - 如何使用带有 php 的 cropit jquery 插件裁剪和上传照片

Question

所以我目前找到了这个名为cropit的照片裁剪插件。 .演示是 here .所以我想做的是抓取裁剪后的照片并将照片的名称上传到 mysql 数据库并使用 php 将其保存到目录中。

到目前为止我有这个:

HTML:

<form method="POST">
    <div class="image-editor">
        <div class="cropit-image-preview-container">
            <div class="cropit-image-preview"></div>
        </div>
            <div class="image-size-label">
            Resize image
        </div>
        <input type="range" class="cropit-image-zoom-input">
        <input type="hidden" name="image-data" class="hidden-image-data" />
        <button type="submit">Submit</button>
    </div>
</form>

jQUERY :

    $('form').submit(function() {
        // Move cropped image data to hidden input
        var imageData = $('.image-editor').cropit('export');
        $('.hidden-image-data').val(imageData);

        // Print HTTP request params
        var formValue = $(this).serialize();
        $('#result-data').text(formValue);

        // Prevent the form from actually submitting
        return false;
    });

我需要的只是 php 设置代码，因为当我裁剪照片并选择提交时，jquery 返回序列化代码，并且出现了我通常不熟悉的所有这些代码。下面是 jquery 返回的序列化代码的几个字符:

image-data=data%3Aimage%2Fpng%3Bbase64%2CiVBORw0KGgoAAAANSUhE...

<强>1。保存base64编码的图片

    <?php
    //save your data into a variable - last part is the base64 encoded image
    $encoded = "data%3Aimage%2Fpng%3Bbase64%2CiVBORw0KGgoAAAANSUhE";

    //decode the url, because we want to use decoded characters to use explode
    $decoded = urldecode($encoded);

    //explode at ',' - the last part should be the encoded image now
    $exp = explode(',', $decoded);

    //we just get the last element with array_pop
    $base64 = array_pop($exp);

    //decode the image and finally save it
    $data = base64_decode($base64);
    $file = 'data.png';

    //make sure you are the owner and have the rights to write content
    file_put_contents($file, $data);

<强>2。获取base64编码图片的文件名

    $encoded = "data%3Aimage%2Fpng%3Bbase64%2CiVBORw0KGgoAAAANSUhE";
    $decoded = urldecode($encoded);
    $exp = explode(';', $decoded);
    $exp = explode(':', $exp[0]);
    $image = array_pop($exp);
    echo ($image);
