Illegal string offset in Laravel
提问by romeo
I'm using Laravel, and it complains about $header inside the Form::text being a illegal string offset, how do I fix this? It doesn't complain if I go straight into the page, but if I submit a form with get method going into the page. I searched around and maybe it thinks $header is an array?
我正在使用 Laravel,它抱怨 Form::text 中的 $header 是非法字符串偏移量,我该如何解决这个问题?如果我直接进入页面,它不会抱怨,但是如果我提交一个带有 get 方法进入页面的表单。我四处搜索,也许它认为 $header 是一个数组?
<?php
$header = null;
if(isset($_GET["header"])) {
$header = $_GET["header"];
}
echo Form::text('header', $header, array('class'=>'form-control', 'placeholder'=>'Tittel'));
?>

Laravel clears the $_GET array. You need to use Input::has('header')
and Input::get('header')
instead.
Laravel 清除 $_GET 数组。您需要使用Input::has('header')
andInput::get('header')
代替。
