CakePHP：具有默认值的日期字段 [英] CakePHP: Date field with default values

问题描述

我使用CakePHP 2.1并有一个日期字段来获取用户的出生日期：

I'm using CakePHP 2.1 and have a date field to get a users date of birth:

例如

echo $this->Form->input('Profile.dob', array('label' => 'Date of Birth'
                                        , 'dateFormat' => 'DMY'
                                        , 'empty' => array('DATE','MONTH','YEAR')
                                        , 'minYear' => date('Y') - 110
                                        , 'maxYear' => date('Y') - 0));

正如你所看到的，我试图使用数组设置默认值，所有都具有默认值DATE。如何获得它，使每个下拉列表都有正确的值？

As you can see I have tried to set the default values using an array, however it just makes them all have a default value of DATE. How do I get it so that each of the dropdowns has the correct value?

推荐答案

这是一个hack，很丑，但由于 empty 选项似乎不支持多个值，它可能是最简单的解决方案 - 除非你要重写整个 dateTime（） / code>函数。 str_replace 不幸的是不允许限制替换的数量，这就是为什么我们必须诉诸 preg_replace 。





It's a bit of a hack and quite ugly, but since the empty option doesn't appear to support multiple values it's probably the easiest solution - unless you want to rewrite the whole dateTime() function. str_replace unfortunately doesn't allow limiting the number of replacements, which is why we have to resort to preg_replace.

$placeholder = '[RandomStringWhichDoesNotAppearInTheMarkup]';

$out = $this->Form->input('Profile.dob', array('label' => 'Date of Birth'
                                            , 'dateFormat' => 'DMY'
                                            , 'empty' => $placeholder
                                            , 'minYear' => date('Y') - 110
                                            , 'maxYear' => date('Y') - 0));

$escapedPlaceholder = preg_quote($placeholder, '/');
$out = preg_replace("/$escapedPlaceholder/", 'DATE', $out, 1);
$out = preg_replace("/$escapedPlaceholder/", 'MONTH', $out, 1);
$out = preg_replace("/$escapedPlaceholder/", 'YEAR', $out, 1);

echo $out;
