[英]Passing Array from Controller to View Using CodeIgniter
我试图将键号为0到9的数组传递给我的视图。 但是，当我尝试回显特定键或所有键的foreach以显示数据时，什么也没有显示。
我的控制器：
$i=0;
$cleanarray = array();
foreach ($phrase as $innerphrase) {
if (is_array($innerphrase)) {
foreach ($innerphrase as $value) {
$cleanarray[$i] = $value;
$i++;
}
}
}
$this->load->view('blogview', $cleanarray);
输出：
Array
(
[0] => On Friday evenings in Thailand, sandwiched between the evening news and a popular soap opera, is a prime-time programme that has been running for three years, or ever since the military took power in a May 22, 2014 coup.

我的观点：
<html>
<head>
</head>
<body>
<h1>I am terrible at PHP!</h1>
<h2><?php echo $0; ?></h2>
</body>
</html>
但是什么也没显示。 我也尝试过以相同的方式使用print_r。 我知道CodeIgniter不允许我在控制器中传递变量，而是允许我直接访问数组中的键。
最终，我想遍历数组并显示所有结果，但是我试图从“ small”开始，至少要使数组的单个元素传递到视图。 如果有人可以解释为什么它不起作用，然后解释使用for或foreach遍历数组的方式，我将不胜感激。
我知道这个问题可能已经回答了很多次，但是对于我一生来说，我无法将对这些问题的回答外推到适用于我的情况的解决方案中。
使用此代码：
控制器 ：
$i=0;
$cleanarray = array();
foreach ($phrase as $innerphrase) {
if (is_array($innerphrase)) {
foreach ($innerphrase as $value) {
$cleanarray[$i] = $value;
$i++;
}
}
}
$array2 = array(); // create a new array
$array2['contents']= $cleanarray; // add $cleanarray to the new array
$this->load->view('blogview', $array2); // pass the new array as the parameter
内部视图文件 ：
echo（“ Contents：”）;
//打印$ cleanarray中的元素
foreach（$ contents为$ val）
echo "$val<br/>";
注意 ：我们在这里不能访问$ array2。 而是使用'$ contents []'。
据我所知，codeigniter不会在没有数组的情况下将数据从控制器传递给视图，因此您可以尝试以下代码，我必须确保它能正常工作。
在您的控制器中
$i=0;
$cleanarray = array();
foreach ($phrase as $innerphrase)
{
if (is_array($innerphrase))
{
foreach ($innerphrase as $value)
{
$cleanarray[$i] = $value;
$i++;
}
}
}
$data['cleanarray'] = $cleanarray
$this->load->view('blogview', $data);
在您的视图中，将数组打印如下： print_r($cleanarray); 我确信此代码将起作用。
快乐编码:)
那不是访问数组变量的方式。 $不代表数组，它代表变量名的开头。 访问$cleanarray的第一个元素的$cleanarray是$cleanarray[0] 。
我承认我不是一个代码点火器编码器，所以我什至不知道那是否是您在“视图”中访问它的方式。 我猜不是，因为控制器中有$this业务。 当然，其他人可以提供该细节。
在控制器中创建$ cleanarray后，应用此
$data['cleanarray'] = $cleanarray;//assign $cleanarray to $data
$this->load->view('blogview', $data);//pass $data to your view
并在视图中访问您的数组
<h2><?php echo $cleanarray[0]; ?></h2>
这是我的建议：
我不建议您使用数字作为变量名。 为了解决这个问题，您可以将其名称以“ _”开头。 例如： $_1 。
因此，在循环中更改$cleanarray[$i] = $value; 进入$cleanarray['_'.$i] = $value; 。
当然，您需要在视图echo $_0;上调用它echo $_0;
