thinkphp Learn small notes (for beginners)

Pre-background conditions

The project root directory is

http://localhost/site/

The new module is called home

We have an add function in the indexcontroller.php.

Public function Add () {
$this->show (' <style type= "text/css" >*{padding:0; margin:0;} div{padding:4px 48px;} body{background: #fff ; font-family: "Microsoft Ya Hei"; Color: #333; font-size:24px} h1{font-size:100px; font-weight:normal; margin-bottom:12px;} p{line-height:1.8em; font- size:36px}</style><div style= "padding:24px 48px;" > echo U (' Index/add ');
$this->display (' index ');

}

Access Path is

Http://localhost/site/home/Index/add

1. Question: How does the output URL be static

U (' Index/add ');
The default value is
/site/index.php/home/index/add.html

' Url_model ' => ' 1 ',//url mode
Return
/site/index.php/home/index/add.html

' Url_model ' => ' 2 ',//url mode
Return
/site/home/index/add.html

' Url_model ' => ' 3 ',//url mode
Return
/site/index.php?s=/home/index/add.html

2. Question: How to shorten the path

Total File index.php

Increase
Define (' Bind_module ', ' home ');

So the whole path was revised to

Http://localhost/site/Index/add

Url_model for 2 of the situation add return path revision change to

/site/index/add.html

3. Question: How to get the U method out of the path is lowercase
Necessary
Turn on debug mode suggest development phase open deployment phase Comment or set to False
Define (' App_debug ', false);

Required 2
config.php

' Url_case_insensitive ' => true,
Template tuning Path {: U (' Index/add ')}

4. Circular Template

Controller layer

$m = m (' Web ');
$result = $m->select ();
$this->assign (' list ', $result);
$this->display (' index ');
View Layer

<foreach name= "list" item= "V" >
{$key}| {$v. Name}
</foreach>

5. Template to find public documents
__public__

Output/site/public

6. Error, correct template hint config.php

' Tmpl_action_success ' => ' index:success ',//home/home/view/index/success.html

' Tmpl_action_error ' => ' index:success ',
Original Jump template file path

Thinkphp\tpl\

Supplemental configuration

Custom configuration: The default configuration for most common parameters in the Convention configuration is the first, because the custom configuration is the lowest priority, and if you do not need to make a special configuration, you can keep the default value, the custom configuration is located in thinkphp/conf/convention.php, the content excerpt as follows:


Copy Code


&lt;?php


/**

* Do not modify this file, if you want to overwrite the values of the Convention configuration, you can set the configuration items in the application configuration that do not conform to the custom


* Configuration name is arbitrary, the system will be converted to lower case


* All configuration parameters can be changed dynamically before they take effect

Copy Code

Application configuration: A public configuration file loaded before all modules are invoked, located in application/common/conf/ config.php, Note If you modify the name of the public module, the location of the public profile will be changed accordingly, there is nothing in the application configuration, you need to add it yourself, as follows:
<?php
Return Array (
' Configuration item ' => ' config value '
);
Mode configuration: If you use an application mode other than normal application mode, you can add the configuration file separately for the application mode, where the file is stored and the naming rules are as follows: Application/common/conf/config_ Application Mode name. PHP, note that mode configuration is only loaded in run mode
Debug Configuration: If Debug mode is turned on, the Debug configuration file for the framework and the Debug configuration file are automatically loaded, where they are located in the thinkphp/conf/debug.php,application/common/conf/debug.php
State configuration: Each application can set its own state under different circumstances, also known as the application scenario, if we want to differentiate the development environment and test environment, define define (' App_status ', ' development ') in the entry file; Then the corresponding configuration file application/common/conf/development.php is loaded, if modified to define (' app_status ', ' test ') in the entry file; Then the corresponding configuration file will be loaded application/common/conf/test.php
Module configuration: Each module will load its own configuration file, and the module in the same directory, such as: application/the current module name/conf/ config.php, if you use an application mode other than normal mode, you can also define the configuration file for the application mode separately, name and storage directory such as: application/Current module name/conf/config_ Application Mode name. PHP, note that this is only loaded in run mode, and the module configuration file is optional.

If you apply a larger profile, you want to split into separate profiles or load additional configuration files to use extended configuration and dynamic configuration.
2. Read configuration

Thinkphp uses the C method to read configuration nodes, which is the meaning of config, note that the parameters of the configuration item are not case-sensitive, C (' Url_model ') and C (' Url_model ') get the same result, but it is recommended that the case be case-sensitive. The configuration parameter name cannot use '. ' because it is used to read two-dimensional parameters, or null if there is no configuration. The method for reading two-dimensional parameter values is as follows: C (' User_config. User_type ');

3. Dynamic configuration

You can write configuration parameters in advance, or you can set them dynamically in a method, using the C method, for example: C (' parameter name ', ' new parameter value '); Dynamic configuration is valid only for the current request and not for other requests. Note that the dynamic configuration method is the same as the method of reading the configuration, except for one more parameter.

4. Extended Configuration

The extended configuration can automatically load additional custom profiles, as well as the format of the configuration format and the project configuration, by setting the extended configuration as follows:

Load Extended configuration file
' Load_ext_config ' => ' user,db ',
