[英]Pushing into a 2 dimensional PHP array
Friends, 朋友们
I am creating a drupal form (its my second one yay!) and I am pulling from the database information about Coursework. 我正在创建一个drupal表单(这是我的第二个表单!),并且从数据库中获取有关Coursework的信息。 a very simple coursework_id and a coursework_name .
一个非常简单的coursework_id和coursework_name 。
Now the usual format to populate a drop down menu in Drupal is as follows: 现在,在Drupal中填充下拉菜单的常用格式如下:
$form['selected'] = array(
'#type' => 'select',
'#title' => t('Selected'),
'#options' => array(
0 => t('No'),
1 => t('Yes'),
),
'#default_value' => $category['selected'],
'#description' => t('Set this to <em>Yes</em> if you would like this category to be selected by default.'),
);
I am trying to pass up my coursework_id and coursework_name in the #options part of the select form described above. 我试图在上述选择表单的#options部分中传递我的coursework_id和coursework_name。
So far I have come up with this line of code: 到目前为止,我已经提出了以下代码行:
foreach ($results as $result) {
$courseworks = (array($result->coursework_id => $result->coursework_name));
}
This matches the required format of the Options but however I can only store one result: 这与选项的所需格式匹配,但是我只能存储一个结果:
Array
(
[2] => Java Programming
)
How could I be able to somehow push the new results. 我怎么能以某种方式推动新结果。 I have tried array_push from PHP but it does seem to work for this case, it can as far as I understand only append a value.
我已经从PHP尝试过array_push,但是在这种情况下它确实起作用,据我了解,它只能附加一个值。
Kind regards, -D 亲切的问候,-D
You should simply try : 您应该尝试:
foreach ($results as $result) {
$courseworks[$result->coursework_id] = $result->coursework_name;
}
Basically you are redefining $courseworks
with every iteration of $results
array. 基本上,您需要在
$results
数组的每次迭代中重新定义$courseworks
。 Try this instead; 试试这个吧;
$courseworks = array();
foreach ($results as $result)
{
$courseworks[] = (array($result->coursework_id => $result->coursework_name));
}
The following should do it for you. 以下应该为您做。 You define the array first and then create keys and assign the relative value:
您首先定义数组,然后创建键并分配相对值:
$courseworks = array();
foreach ($results as $result) {
$courseworks[$result->coursework_id] = $result->coursework_name;
}
