使用PHP中带有URL的上传图像定义文件大小

Question

[我正在使用本教程Upload Image from URL using PHP with Ajax，并使用少量字段添加PHP Foreach以进行多次上传，并且一切正常，但是如何为从2MB之类的URL定义最大上传文件大小？

可以用PHP或Jquery代码定义吗？ （对不起我的英语不好）谢谢

HTML表单

<form id="form" method="post" action="upload.php">
<input name='url[]' type="text" id="image_url" placeholder="link 1:"  class="link_input" name="url"/><br/>
<input name='url[]' type="text" id="image_url" placeholder="link 2:"  class="link_input" name="url"/><br/>
<input name='url[]' type="text" id="image_url" placeholder="link 3:"  class="link_input" name="url"/><br/>
<input name='url[]' type="text" id="image_url" placeholder="link 4:"  class="link_input" name="url"/><br/>
<input name='url[]' type="text" id="image_url" placeholder="link 5:"  class="link_input" name="url"/><br/>
<br/><input type="submit" name="upload" id="upload" value="Go"/>
</form>

Answer 1

您可以在php.ini中定义upload_max_filesize

; Maximum allowed size for uploaded files.
upload_max_filesize = 40M

; Must be greater than or equal to upload_max_filesize
post_max_size = 40M
