Laravel - trying to echo a value from an array in a blade template. Works using php echo() but not blade syntax
提问by Inigo
I have an array that looks like:
我有一个看起来像的数组：
$myArray = array(
'firstRow' => array(
0 => array(
'id' => 1
'title' => 'First Cat.'
),
1 => array(
'id' => 2
'title' => 'Second Cat.'
)
),
'SecondRow' => array(
0 => array(
'id' => 3
'title' => 'Third Cat.'
),
1 => array(
'id' => 4
'title' => 'Fourth Cat.'
)
)
);
This is being passed to my blade template. I can echo out values using raw php like:
这将传递给我的刀片模板。我可以使用原始 php 回显值，例如：
<?php echo $myArray['firstRow'][0]['title'] ?>
Which works as expected. However, when I try to do what I thought was exactly the same thing using blade's syntax:
这按预期工作。但是，当我尝试使用刀片的语法做我认为完全相同的事情时：
{{ $myArray['firstRow'][0]['title'] }}
I get the error:
我收到错误：
Trying to get property of non-object
试图获取非对象的属性
?
?

OK.. I just solved this. Stupid. Sorry and thanks to the other commenters here.
好的..我刚刚解决了这个问题。愚蠢的。抱歉并感谢这里的其他评论者。
The problem was that I had come code underneath this line which was commented out using HTML comments, ie <-- --> But it also contained blade syntax which of course is PHP and so is still firing. I would normally have noticed but due to my GUI not highlighting blade syntax it went unnoticed.
问题是我在这行下面的代码中使用了 HTML 注释，即 <-- --> 但它也包含当然是 PHP 的刀片语法，因此仍在触发。我通常会注意到，但由于我的 GUI 没有突出显示刀片语法，因此没有引起注意。

I'm afraid you are suspecting of the wrong line of code, because:
恐怕您怀疑代码行错误，因为：
Trying to get property of non-object
Is to something being used not as an array, but as an object:
不是用作数组，而是用作对象的东西：
{{ $myArray->firstRow->get(0)->title }}
So, your error is not exactly in this line.
所以，你的错误并不完全在这一行。
But can be sure by getting the generated view source code in app/storage/views.
但是可以通过在app/storage/views.
