我遇到了这个错误：无法运行查询：SQLSTATE [23000]：完整性约束违规：1048 列'membersince'不能为空

在这里，我尝试运行我的注册页面。

这是代码。我错过了什么吗？我检查了我的数据库表/输入名称都正确命名为“membersince”，那么到底出了什么问题？:(

我遇到了类似的问题，但我已经解决了，所以想分享一下，这可能对某人有用...

通常当你遇到

完整性约束违规：1048 列 NAME_OF_YOUR_COLUMN

如果未设置变量，通常会发生这种情况，在您的情况下，导致此问题的关键是

<input class="text" name="membersince" 
       value=" <?php> $todaysdate = date("Y-m-d"); echo $todaysdate?>" 
       type="text" disabled>

因此，如果您在这里看到，您正在使用disabled该特定字段的属性，因此，您的form元素不会将此字段的值发送到服务器，因此......当您在查询中使用以下内容时

':membersince' => $_POST['membersince']

将导致数组中null没有键。因此，请确保应设置您分配的变量。membersince$_POST

尝试使用readonly而不是disabled. disabled 字段值不能通过form标签发布。

<input class="text" name="membersince" 
       value=" <?php echo date("Y-m-d"); ?>" 
       type="text" readonly="readonly">

我面临同样的问题。我的表单中的“字段名”和数据库的列名不同。我的问题是： "Integrity constraint violation: 1048 Column 'MoneyMethod' cannot be null"。我的表单输入标签：{!! Form::select("MoneyMethod", $MoneymethodInfo, null,["class"=>"form-control MoneyMethod required","id"=>"MoneyMethod"]) !!}，请注意“MoneyMethod”的拼写，在我的数据库表$table->string('MoneyMethod', 100);中，“MoneyMethod”的拼写与表单相同，但在我的控制器中$riskfund->Moneymethod = Input::get('Moneymethod');仔细查看“Moneymethod”的拼写与我的表单和数据库表列不同。更正拼写后，它现在可以工作了。因此，请检查表单、控制器、数据库表中“membersince”的拼写。它可能会帮助你。
