[英]How to properly loop three dimensional array in twig?
I have an array setup like so; 我有一个像这样的阵列设置; and I cant seem to loop through the values with twig:
我似乎无法用树枝循环遍历这些值:
array (size=1)
'hash' =>
array (size=7)
0 =>
array (size=4)
'key1' => "val"
'key2' => "val"
'key3' => "val"
'key4' => "val"
1 =>
array (size=4)
'key1' => "val"
'key2' => "val"
'key3' => "val"
'key4' => "val"
...
The template code I'm using (in its nth iteration): 我正在使用的模板代码(在第n次迭代中):
{% for i in hash %}
{% for j in i %}
<td>{{ j.key1 }}</td>
<td>{{ j.key2 }}</td>
<td>{{ j.key3 }}</td>
<td>{{ j.key4 }}</td>
{% endfor %}
{% endfor %}
I keep getting Array to string conversion
errors with the above twig template code. 我继续使用上面的twig模板代码获取
Array to string conversion
错误。
With the help of vijay4vijju and his reference to dump
I was able to loop over the array. 在vijay4vijju和他对
dump
引用的帮助下,我能够遍历数组。
Only a single loop was needed: 只需要一个循环:
{% for key,val in hash %}
<tr>
<td>{{ val.key1 }}</td>
<td>{{ val.key2 }}</td>
<td>{{ val.key3 }}</td>
<td>{{ val.key4 }}</td>
</tr>
{% endfor %}
I would have selected his answer but it technically wasn't the answer, and dump was just a reference to the dump
manual. 我会选择他的答案但技术上不是答案,而dump只是对
dump
手册的引用。
To enable debugging in twig I used: 为了在twig中启用调试,我使用了:
$twig = new Twig_Environment($loader, array(
'debug' => true,
));
$twig->addExtension(new Twig_Extension_Debug());
To troubleshoot this issue I used: 要解决此问题,我使用了:
{% for key,val in hash %}
<pre>{{ dump(val) }}</pre>
<tr>
<td>{{ val.key1 }}</td>
<td>{{ val.key2 }}</td>
<td>{{ val.key3 }}</td>
<td>{{ val.key4 }}</td>
</tr>
{% endfor %}
I used this for printing multi-dimensional array in twig, hopefully it will work. 我用它在树枝上打印多维数组,希望它能起作用。
{% for item in hash %}
{% for firstLevelItem in item %}
<ul>
<li>{{ firstLevelItem.comments }}</li>
</ul>
{% endfor %}
{% endfor %}
