[英]PHP Warning htmlentities() expects parameter 1 to be string, array given
I have a form to inject data in a database. 我有一种将数据注入数据库的形式。 When user clicks
submit
button this error shows up in a <input type=text>
field. 当用户单击
submit
按钮时,此错误显示在<input type=text>
字段中。 I have been looking around for a solution for hours but I do not know how to fix this. 我一直在寻找解决方案达数小时之久,但我不知道该如何解决。

You are passing the whole $_POST variable to serialize in the product name input (that's why the error says 'array given'). 您正在传递整个$ _POST变量以在产品名称输入中进行序列化(这就是为什么错误显示“给定数组”的原因)。
Check this line: 检查这一行:
<input type="text" name="prod_name" id="prod_name" class="form-control" value="<?=((isset($_POST['prod_name']))?sanitize($_POST):' ');?>">
And change it with this: 并通过以下方式进行更改:
<input type="text" name="prod_name" id="prod_name" class="form-control" value="<?=((isset($_POST['prod_name']))?sanitize($_POST['prod_name']):' ');?>">
