Laravel validation regex, breaks in view
提问by Alex
So, I have the following rules in my model:
所以，我的模型中有以下规则：
public static $rules = array(
'name' => 'required|alpha_dash|unique:subsidiaries',
'internal_number' => 'required|alpha_dash|unique:subsidiaries',
'expedition_rate' => array('required', 'regex:/^[0-9]{1,3}(\.?)[0-9]{1,2}$/'),
'hundred_kg_rate' => array('regex:/^[0-9]{1,5}(\.?)[0-9]{1,2}$/'),
'handling' => array('regex:/^[0-9]{1,3}(\.?)[0-9]{1,2}$/'),
'insurance' => 'required|numeric',
);
But, for some reason, when the regex is applied in the patternattribute tag in html... it breaks!
但是，由于某种原因，当pattern在 html的属性标记中应用正则表达式时……它会中断！
Result:
结果：
<input required="true" pattern="^[0-9]{" class="form-control" ....>
_________
\
=> This right here should be
^[0-9]{1,3}(\.?)[0-9]{1,2}$

Try using like this.
尝试这样使用。
array(
'field' => 'regex:[a-z]'
);
Hope this would helpful.
希望这会有所帮助。

Try escaping the curly braces... I bet PHP is expecting to parse a variable inside, like this:
尝试转义花括号...我敢打赌 PHP 期望解析内部的变量，如下所示：
$var = 'something';
echo 'The value is {$var}.';
// Outputs:
// The value is something.
Contrast this with:
对比一下：
$var = 'something';
echo 'The value is \{$var\}.';
// Outputs:
// The value is $var.
The part that confuses me though, is that these are within single quotes, and so this shouldn't happen. Maybe a Laravel thing?
不过让我感到困惑的部分是这些都在单引号内，所以这不应该发生。也许是 Laravel 的东西？
