input type="file"多图片上传

单个的input type="file"表单也是可以实现多图片上传的

代码如下:

    <form action="manypic.php" method="post" enctype="multipart/form-data">
        <input type="file" name="manypic[]" multiple>
        <input type="submit">
    </form>

这里要给file表单加上一个multiple属性 multiple="multiple"也可以

name的属性值后面要加上[]这样就可以了  print_r($_FILES)可得到如下信息:

Array
(
 [manypic] => Array  (  [name] => Array  (  [0] => 1.png  [1] => bg.jpg  )   [type] => Array  (  [0] => image/png  [1] => image/jpeg  )   [tmp_name] => Array  (  [0] => D:\xampp\tmp\php8C53.tmp  [1] => D:\xampp\tmp\php8C54.tmp  )   [error] => Array  (  [0] => 0  [1] => 0  )   [size] => Array  (  [0] => 44113  [1] => 325257  ) 　　　　 ) )
这里我上传的是两张图片
另外你也可以提交多个input type="file"上传域,代码如下:
    <form action="manypic.php" method="post" enctype="multipart/form-data">
        <input type="file" name="pic1">
        <input type="file" name="pic2">
        <input type="submit">
    </form>
php页面的print_r的打印结果:

Array
(
 [pic1] => Array  (  [name] => bg.jpg  [type] => image/jpeg  [tmp_name] => D:\xampp\tmp\phpF661.tmp  [error] => 0  [size] => 325257  )   [pic2] => Array  (  [name] => 1.png  [type] => image/png  [tmp_name] => D:\xampp\tmp\phpF671.tmp  [error] => 0  [size] => 44113  ) )
