tp3.1 (2)

One, Custom function

1, U () URL

Configuration data for 2, C () conf

3. Custom Functions

In the user's application, common-"Create common.php, then write your own method and use it in the controller,

4, dump () print array is more harmonious than var_dump ()

II. Create a project template

Create a template in the TPL

Create the index (presentation method) folder and create the index.html file in index

The template can be directly connected in the index controller ($this->display)

This is the index method of the index controller.

To enable the test method to display the index controller

$this->display (' index/test ')

or $this->display (' test ')

Iii. assignment and output of templates

1th:

In the Controller->index ()

$name = "Doson";

In tpl->index->index.html

So how to accept the value of $name: <?php echo $name?>

2nd:

In the Controller->index ()

$this-Assign (' name ', $name);

In tpl->index->index.html

So how to accept the value of $name: <?php echo $name?>

When using the second way: can be infinitely assigned, and the first method can only be assigned to a number of $this->assign (' name ', ' Zhang San ')->assign (' age ', 12);

Iv. template engine for TP

Thinkphp built-in engine class: thinkphp\lib\template\thinktemplate.class.php

Five, the template engine variable output and operation

In the Controller->index ()

$me [' name ']= ' yyyyy ';

$me [' Age ']=12;

$this->assign (' Me ', $me);

In the tpl->index->index.html:

Method One: {$me [' name ']}

Method Two:

{$me. Name}

Comment Method: {//$me. Name}

A value that is undefined can be set to a default value

{$me. sex|default= ' Man '}

To perform operations on a template

The operation must be written in the form of an array {$me [' Age ']+1}

VI: thinkphp function and system parameters of template engine

Method one: In controller-"index

echo $name =substr (MD5 ($me [' name ']), 0,5);

Method Two: In tpl-"index-" index

{$me [' name ']|md5|substr=0,5}

Call of Time

In controller-"index

$now =time ();

In tpl-"index-" index

{$now |date= ' y-m-d h:i:s ', # # #} where # # #表示的是变量, that is, $now

{$Think. Now}

system function {$Think. now}
{$Think. Version}
{$Think. Server.http_host}

Vii. volist and foreach loops of the thinkphp template engine

In the Contoller:

$person =array (
1=>array (' name ' = ' jack6 ', ' age ' = ' 12 '),
2=>array (' name ' = ' jack5 ', ' age ' = ' 15 '),
3=>array (' name ' = ' jack4 ', ' age ' = ' 12 '),
4=>array (' name ' = ' jack1 ', ' age ' = ' 11 '),
5=>array (' name ' = ' jack2 ', ' age ' = ' 15 '),
);
$this->assign (' person ', $person);
$this->display ();

In the TPL:

<volist name= "Person" id= "Data" >
{$data [' name '}}-----{$data [' age ']}<br/>
</volist>
From the second start, Loop 3
<volist name= "Person" id= "Data" offset= ' 1 ' length= ' 3 ' >
{$data [' name '}}-----{$data [' age ']}<br/>
</volist>

Set default values

<volist name= "Person" id= "Data" offset= ' 1 ' length= ' 3 ' empty= ' I have no statistics ' >
{$data [' name '}}-----{$data [' age ']}<br/>
</volist>

Foreach

<foreach name= ' person ' item= ' data ' >
{$data [' name '}}------{$data [' age ']}<br/>
</foreach>

Viii. thinkphp for Loop

eq= neq!= gt> egt>= lt<

elt<= Heq = = = nheq!==

Controller

: for ($i =0; $i <10; $i + +) {
echo $i;
}

Template

<for start= ' 1 ' end= ' comparision= ' elt ' name= ' K ' >
{$k}<br/>
</for>

Ix. if judgment of TP template engine

In the controller:

$num =10; $this->assign (' num ', $num);

In the TPL:

<if condition= "$num gt ten" >num greater than 10

<elseif condition= "$num lt ten"/>num less than 10

<else condition= "$num eq ten"/>num equals 10

</if>

The output is: num=10

X. SWITCH judgment of TP template engine

In the controller:

$name = ' Xiaohong '; $this->assign (' name ', $name);

In the TPL:

<switch name= "Name" >

<case value= "Xiaohong|" > Xiaoming, get out of the way </case>

<case value= "Laoshi" > Xiao Ming roll </case><defalut/> xiaoming, fuck off.

</switch>

Comparison tab of the TP template engine

< comparison label name= "variable" value= "value of comparison" >

</Compare Tags >

Method One,

<eq name= "num" value= "ten" >num=10</eq>

<NEQ name= "num" value= "ten" > Num!=10</neq>

Method Two,

<eq name= "num" value= "ten" >num=10 <else/>num!=10</eq>

Method Three,

<compare name= "num" value= "ten" type= "EQ" >num=10<else/>num!=10</compare>

12. TP template Engine's interval label

In/notin

Method One,

<in name= "num" value= "1,2,4,7" > in range </in>
<notin name= "num" value= "1,2,4,7" > Not in range </notin>

Method Two,
<in name= "num" value= "2,4,7" > in range <else/> not in this range </in>

Method Three,

<range name= ' num ' value= ' 12,2,4 ' type= ' in ' > has 2 this number <else/> no </range>
Between/notbetween: Judging interval range I

Method One,

<between name= ' num ' value= ' 1,19 ' > is really here </between><br/>
<notbetween name= ' num ' value= ' 13,9 ' >bu really here </notbetween>
<br/>

Method Two,
<between name= ' num ' value= ' 1,19 ' > is really here <else/> no longer </between><br/>

13, ternary operator

{$num >17? ' Greater than 17 ': ' Not greater than 17 '}

14. Template Combat

Class Indexaction extends Action {
Public Function index () {
$person =array (
1=>array (' name ' = ' jack1 ', ' age ' = ' 16 '),
2=>array (' name ' = ' jack2 ', ' age ' = ' 17 '),
3=>array (' name ' = ' jack3 ', ' age ' = ' 18 '),
4=>array (' name ' = ' jack4 ', ' age ' = ' 19 '),
);
$this->assign (' person ', $person);
$this->display ();
}

<foreach name= ' person ' item= ' data ' >
<egt name= ' data.age ' value= ' >{$data. Name} has grown up.
<else/>{$data. Name} is also a child </egt>
</foreach>

Introduce Php:<php>echo $person [1][' name ']</php> in the template

The debugging method of XV and thinkphp

Method One,

In the app-"conf-" debug.php, in the debug.php file can change the value of config.php to debug

Method Two,

Debugging specifically for developers

Turn on trace information for a page

In the debug.php file: ' Show_page_trace ' =>true,

Method Three,

Trace (' Name ', C (' name '));

Method Four,

Dump ($_server);

Method Five,

G (' run ');

for ($i =0; $i <1000; $i + +) {$count + = $i;}

Echo G (' Run ', ' end ');//units: milliseconds

Do the programming, complex logic: view dead loops, diffuse loops
