Views and built-in tags of thinkPHP5.0 framework

Table of contents

1. View

a) load the page

1. Inherit the system controller class

return $this->fetch(parameter 1, parameter 2, parameter 3, parameter 4);

Parameter 1 (string): template rendering
parameter 2 (array): template assignment
parameter 3 (array): template replacement
parameter 4 (array):

2. Use helper functions

return view();
The parameters of view are the same as fetch

3. Use the view class (not recommended)

$view=new View();

return $view->fetch();

b) template assignment

1. The assign method in the controller class

$this->assign('name',$name);
$this->assign('city',$city);

load page
return view();

2. Through the fetch method

return $this->fetch('',['name'=>$name,'city'=>$city]);

3. Helper function

return view('',['name'=>$name,'city'=>'西安']);

4. Object assignment
$this->view->name="Haoge";
$this->view->city="Linfen";

return view();

2. Built-in tags

1. Volist cycle

name The id of the data to be traversed
is similar to the value offset in foreach,
the starting position of the intercepted data
length the number of intercepted data
mod odd and even number empty use the key number
if the data is empty

2. foreach loop

name The data item that needs to be traversed
, similar to the value key in foreach
, similar to the key in foreach

{foreach name="data" item="val" key="abc"}
 {$abc} {$val.id} {$val.name}
{/foreach}

3. for loop

start start value
end end value
comparison comparison condition
step step number
name loop variable name default i

{for start="0" end="10" comparison="elt" step="2" name="abc"}
{$abc}
{/for}

{for start="10" end="0" comparison="gt" step="-1"}
{$i}
{/for}

4. Compare tags

{eq name="a" value="11"}correct{/eq}
{neq name="a" value="11"}correct{/neq}
{lt name="a" value="11"}correct {/lt}
{gt name="a" value="11"}Correct{/gt}
{egt name="a" value="11"}Correct{/egt}
{elt name="a" value=" 11"}correct{/elt}
{heq name="a" value="11"}correct{/heq}
{nheq name="a" value="11"}correct{/nheq}

5、if

{if condition="$a eq $b"}

a and b are equal
{else /}

a and b values are not equal

{/if}

6、switch

{switch name="week"}
{case value='1'}Monday{/case}
{case value='2'}Tuesday{/case}
{default /} Sunday
{/switch}

7. in and notin are similar

{in name="week" value="0,1,2,3,4,5,6"}
legal data
{else /}
illegal data
{/in}

8、between 和 notbetween

{between name="week" value="0,6"}
legal data
{else/}
illegal data
{/between}

9、原生PHP
{php}
echo "123";
{/php}

<?php
echo "456";
?>
