What does eq mean in thinkphp

The eq tag in thinkphp seems not commonly used, but it is essential

For example, like a certain status, switch Wait, you can't directly read the fields in the database to the customer, and the customer can't understand it, right?

So we can use the eq tag to solve this little problem.

For example: I have a status field in the database, indicating a certain status. I stipulate it: 0 is inactive, 1 is activated

Now I want to display the data of the entire table to Users look, what should I do?

One thing that is certain is that we cannot read 0 and 1 directly. In the front-end template,

looks like this: <td>{$vo.status}</td&gt ;

Let users see it directly. This is not ideal. The customer experience must be poor. . .

Solution:

Use the eq tag to determine the value of status and make a small blind trick:

<eq name="vo.status" value="0">未激活</eq>
<eq name="vo.status" value="1">已激活</eq>

Of course, if it is not a particularly complicated requirement, it can be abbreviated

Like this:

<eq name="vo.status" value="0">未激活<else/>激活</eq>

Note: eq means that if the values ​​​​of name and value are equal, the content between the <eq> tags will be output. The name here should not be written as {$vo.status }

Otherwise, no matter how you write it, it will be the value of <else/>

Of course, this is just one of the comparison tags in thinkphp. For more information, please refer to the thinkphp manual
