php foreach 语句的数组问题（代码点火器）

Question

Currently I have

private function getYears()
{
    return array('Test1', 'Test2', 'Test3', 'Test4');
}

in the index:

$years = $this->getYears();

and in the view

<select>
    <?php foreach ($years as $row):?>
        <option><?=$row?></option>
    <?php endforeach;?>
</select>

The select box doesn't get filled?

How can I fix this?

[edit]

So far I noticed that the $years is empty and the getYears is not being called.. no idea why yet..

Answer 1

I don't know what you're iterating over.

You've passed the values to $years , yet you're iterating over $pages . Is that a typo?

In any case, you're iterating over an array of arrays. Do a var_dump on the $row variable and check what you're actually iterating over.

Answer 2

<select>
    <?php foreach ($years as $row):?>
        <option><?=$row?></option>
    <?php endforeach;?>
</select>

Answer 3

Not advisable iteration, it is better to iterate in the controller and use view to create get html tags and just pass the data to the main view.
