In short, a controller corresponds to a view, and a method corresponds to a template. Let's go to the figure above.
2. Assign value to template
Assign() function is used to assign template. The first parameter of assign() function is to give a user-defined name to the value, and the second parameter is the value
Chestnut:
public function testview(){ $date=Db::name("goods")->select();//Database query commodity table returns a dataset $this->assign('date',$date); //Give dataset to date return $this->fetch(); }
Then the corresponding template will get the date data set. Here is how to use the data set in the template and directly add the code:
<table> <tr> <th>commodity ID</th> <th>Trade name</th> <th>commodity price</th> <th>operation</th> </tr> {foreach $date as $value} <tr> <th>{$value.id}</th> <th>{$value.goods_name}</th> <th>{$value.price}</th> <th><a href="#"> delete < / th > </tr> {/foreach} </table>
III. how to comment in the template
Ordinary HTML annotation cannot annotate the content in , because ThinkPHP will find "{}" to process the content in braces, so here we use a special method to annotate, such as {/ * annotated content * /} to annotate the following chestnut
<table> <tr> <th>commodity ID</th> <th>Trade name</th> <th>commodity price</th> <th>operation</th> </tr> <!--For multiline annotation{/*Content of notes*/}--> {/* <tr> <!--Use {/ / comment content} -- > {//<th>{$value.id}</th>} <th>{$value.goods_name}</th> <th>{$value.price}</th> <th><a href="#">Delete </th> </tr> {/foreach} */} </table>
IV. using functions in templates
strtoupper, md5 and other functions can also be used in the template. The following shows how to use them.
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <title>test</title> </head> <body> <!-- The use function in the template, for example, passes in a jack，Use strtoupper()Function to uppercase --> {$name | strtoupper} <br> <!--call md5 Function to name encryption--> {$name | md5}<br> <!--Multiple uppercase letters after function encryption--> {$name | md5 | strtoupper}<br> <!--Use specified class Methods in, such as call VERSION Obtain ThinkPHP Version number--> {:think\\APP::VERSION} </body> </html>
