调用自定义组图的实际图片宽度

 <?php if ($zutu) { $key=0; foreach ($zutu as $c) { ?>

                                    { 
                        {php $cc = current($zutu);}
                        href: "{dr_get_file($cc)}",
                        src: "{dr_get_file($c)}", 
                        img: "{dr_get_file($c)}", 
                        width: "237", height: "150", 
                        title: "{$t['title']}" 
                    },
                    <?php $key++;} } ?>

我想调用该图片的宽度的数值，写成100%和auto都不行，系统里有没有这个变量可以调出来？

<?php $size = getimagesize(dr_get_file($c)); ?> width: "{$size[0]}", height: "{$size[1]}",
你这又是用循环又是用单一输出，思维太混了，影响页面速度啊

<?php if ($zutu) { $key=0; foreach ($zutu as $c) { ?>
                      { index: {$key+1}, 
                        href: "{dr_get_file($c)}",
                        src: "{dr_get_file($c)}", 
                        img: "{dr_thumb($c, 200, 200)}", 
                        {php  $size = getimagesize(dr_thumb($c)); }
                        width: "{$size[0]}", height: "150",
                        title: "{$t['title']}" 
                    },
<?php $key++;} } ?>

调出来了，感谢大神，确实现在这个代码的执行效率太慢，页面打开明显慢多了，怎么优化一下速度呢？

小波工作室这个代码执行出现系统故障！但是我找不出错在哪里?

游子2018 试试这样写

<?php
if($zutu)
{
   $key=0;
   foreach($zutu as $c)
   {
?>
{
index: {$key+1},
href: "{dr_get_file($c.file)}",
src: "{dr_get_file($c.file)}",
img: "{dr_thumb($c.file, 200, 200)}",
<?php
$at = $ci->get_attachment($c.file);
if ($at && $at.attachinfo)
{
    $size=[$at['attachinfo']['width'], $at['attachinfo']['height']];
}
else
{
    $size = getimagesize(dr_get_file($c.file));
}
?>
width: "{$size[0]}",
height: "{$size[1]}",
title: "{$t['title']}"
},
<?php
      $key++;
   }
}
?>

满意答案
