Type error: Argument 1 passed to Illuminate\Database\Grammar::parameterize() must be of the type array, string given
提问by Arthur Tarasov
I am trying to build a tagging system using taggingJSon the frontend and laravel-taggingon the backend. I got them both working separately, but I cannot get the tags generated by taggingJS to enter the database.
我正在尝试在前端使用taggingJS并在后端使用laravel-tagging来构建标记系统。我让他们都分开工作，但我无法让 taggingJS 生成的标签进入数据库。
My Laravel controller looks like this:
我的 Laravel 控制器如下所示：
public function storeData(Request $request)
{
$link = new Links;
$link->tag_name = $request->taggone;
$link->save();
$link->tag(explode(',', $request->taggone));
$link->save();
return view('pages.postdata', compact('tags'));
}
The HTML code looks like this:
HTML 代码如下所示：
<div class="example-wrapper">
<div class="tags well">
<label for="tag" class="control-label">Tag</label>
<div data-tags-input-name="taggone" id="tag"></div>
</div>
</div>
I left taggingJS' Javascript unchanged like this (I am not sure if it is even relevant to this issue):
我让 taggingJS 的 Javascript 像这样保持不变（我不确定它是否与这个问题相关）：
<script>
// jQuery on Ready example
(function( $, window, document, undefined ) {
$( document ).ready(function() {
var t = $( "#tag" ).tagging();
t[0].addClass( "form-control" );
// console.log( t[0] );
});
})( window.jQuery, window, document );
</script>
If I understand it correctly, the tags input into the field taggoneare supposed to be requested by the controller and saved into the database. But when I submit the form I get the error:
如果我理解正确，输入到字段taggone中的标签应该是控制器请求并保存到数据库中的。但是当我提交表单时，我收到错误：
Type error: Argument 1 passed to Illuminate\Database\Grammar::parameterize() must be of the type array, string given, called in /home/vagrant/Code/Laravel/vendor/laravel/framework/src/Illuminate/Database/Query/Grammars/Grammar.php on line 678
类型错误：传递给 Illuminate\Database\Grammar::parameterize() 的参数 1 必须是数组类型，给定的字符串，在 /home/vagrant/Code/Laravel/vendor/laravel/framework/src/Illuminate/Database/ 中调用第 678 行的 Query/Grammars/Grammar.php
Can I have an advice on how to get it to work?
我可以就如何让它发挥作用提出建议吗？

It looks like you're passing a string (instead of an array) from your form. Try to adjust the htmlby adding []to the taggoneinput like this:
看起来您正在从表单中传递一个字符串（而不是数组）。尝试html通过将[]添加到标签输入来调整，如下所示：
<div data-tags-input-name="taggone[]" id="tag"></div>
If you're still receiving the same error, post the complete error message somewhere.
如果您仍然收到相同的错误，请在某处发布完整的错误消息。

You can do this way
你可以这样做
public function storeData(Request $request)
{
$link = new Links;
$link->tag_name = $request->taggone;
$link1 = $link->save(); //Store it to a variable
//If your $request->taggone already an array you don't have to explode it, directly use $link1->tag($request->taggone);
// Explode if it's a string and use $link1->tag(explode(',', $request->taggone));
$link1->tag($request->taggone); //In case $request->taggone array
//OR
$link1->tag(explode(',', $request->taggone)); //In case $request->taggone string
$link1->save();
return view('pages.postdata', compact('tags'));
}
