getimagesize with Laravel 4 Blade template
提问by Lynx
How can I use getimagesize using Laravel 4's blade template?
如何使用 Laravel 4 的刀片模板使用 getimagesize？
I have the following foreach loop:
我有以下 foreach 循环：
@foreach($category as $inventory)
{{ HTML::image('small/' . $inventory->image . '', '' . $inventory->name . '', array('class' => 'scale-with-grid', 'height' => '280', 'width' => 'auto')); }}
@endforeach
I want the getimagesizefunction to display the height and width for that specific image in the heightand widthimage attributes. Every time I attempted to do it myself but could not get it working correctly.
我希望该getimagesize函数在height和width图像属性中显示该特定图像的高度和宽度。每次我尝试自己做但无法正常工作时。

This is what I have tried so far. I think my biggest problem is I am not sure how to access the small folder inside my public directory. I tried using public_path but it's returning a array to string conversion error. However, it seems like when I dump public_path it shows the correct path.
这是我迄今为止所尝试的。我认为我最大的问题是我不确定如何访问公共目录中的小文件夹。我尝试使用 public_path 但它返回一个数组到字符串转换错误。但是，当我转储 public_path 时，它似乎显示了正确的路径。
{{ $image = getimagesize(public_path('small/' . $inventory->image . '')) }}
{{ var_dump($image); die; }}
I am using wamp and when I dump public_path this is the first source I get.
我正在使用 wamp，当我转储 public_path 时，这是我得到的第一个来源。
string 'C:\wamp\www\product\public/small/image.jpg' (length=71)
I am not sure if that's the issue. When I copy and paste that into my browser it will load the image with no problem
我不确定这是否是问题所在。当我将其复制并粘贴到我的浏览器中时，它会毫无问题地加载图像

Try this
尝试这个
list($width, $height) = getimagesize("Full path of the image");
Now you can use $width and $height.
现在您可以使用 $width 和 $height。

I was able to solve it by not using blade brackets and inserting
我能够通过不使用刀片支架并插入来解决它
<?php list($width, $height) = getimagesize(asset('small/' . $inventory->image . '')); ?>
{{ HTML::image('small/' . $inventory->image . '', '' . $inventory->name . '', array('class' => 'scale-with-grid', 'height' => 280, 'width' => $width)); }}

I would suggest against writing such a code in controller. If you need to repeat this somewhere else (which is the case most of the time) then writing it in controller is a bad idea. Keep you controllers simple. I would probably solve this in my repository or something like that... but if its small project that i suggest defining HTML::macro
我建议不要在控制器中编写这样的代码。如果您需要在其他地方重复此操作（大多数情况下都是这种情况），那么将其写入控制器是一个坏主意。让您的控制器保持简单。我可能会在我的存储库或类似的东西中解决这个问题......但是如果它的小项目我建议定义 HTML::macro
HTML::macro('imageWithSize', function($url, $alt = null, $attributes = array(), $secure = null)
{
// original - HTMl::image($url, $alt = null, $attributes = array(), $secure = null);
// get image path - change this to whatever suits you
$image_path = public_path($url);
// get image size
list($width, $height) = getimagesize($image_path);
// add those to attributes array
$attributes['width'] = $width;
$attributes['height'] = $height;
return HTML::image($url, $alt, $attributes, $secure );
});
You can see the original implementatio of HTML::image here
你可以在这里看到 HTML::image 的原始实现
