[英]Inserting drop down data from one table to another
I have a table which consists of just id & category, I then have a form with a drop down box which uses the category column to populate it. 我有一个仅由id和category组成的表,然后有一个带有下拉框的表单,该表单使用category列进行填充。 The next step is when the submit button is clicked it sends all the data into another table [product_table], All the data submits to the product table, but rather than the category name inserting it is inserting the id. 下一步是单击“提交”按钮时,它将所有数据发送到另一个表[product_table]中,所有数据都提交到产品表中,而不是插入类别名称而是插入ID。 I've tried multiple fixes to no avail, I'm thinking the easiest way would be to take outputted category '1','2','3'... and use a query to convert it to 'hat,'shirt',shoes'... using the category_table. 我已经尝试了多种修复措施,但都无济于事,我认为最简单的方法是采用输出的类别“ 1”,“ 2”,“ 3” ...,并使用查询将其转换为“帽子” ',shoes'...使用category_table。 I'm not 100% sure how to do this though, 我不确定100%如何做到这一点,

==> I know there's a few spelling mistakes in the code (usually category/catagory) but it's consistent throughout, ==>我知道代码中存在一些拼写错误(通常是类别/类别),但在整个过程中都是一致的,
Any help/advice would be great appreciated 任何帮助/建议将不胜感激
The select
element is used to create a drop-down list but The option value=""
tags inside the element define the available options in the list with values. select
元素用于创建下拉列表,但是元素内的option value=""
标签使用值定义列表中的可用选项。
In your case, the mistake is here, as you are putting $row['id']
in value 在您的情况下,错误就在这里,因为您将$row['id']
赋值
echo "<option value='".$row['id']."'>'".$row['category']."'</option>";
So if you want the name
instead of the id
, have to change the option value
因此,如果您想要name
而不是id
,则必须更改option value
echo "<option value='".$row['category']."'>'".$row['category']."'</option>";
