Thinkphp Study Summary

thinkphp3.2 Handbook Catalog: http://www.kancloud.cn/manual/thinkphp/1678

First, page jump

1.URL mode is used to direct requests to modules, controllers, and operations, such as PathInfo mode: The http://localhost/index.php/home/user/login/var/value/method does not exist, then the template

2. Page Jump $this->success ("New Success", '/user/index ');

$this->success ("Add Success", U (' Office/index ')); Jump method

3. Page redirection $this->redirect ("Office/index"); Jump method

4. Display template $this->display ("/office/officejudge");

$this->display (' Member:read '); The default view directory is typically

5.ajax return $this->ajaxreturn (eval ("Return $xsq;"));

U method: Default Current module, U (' Office/index ') for Office Controller index method

Second, variable acquisition

1. Background access, recommended I method, note how to submit how to take, value for square brackets

$id = $_get[' id ']; Equivalent to $id = I (' Get.id, "") does not exist return ""

2. Front desk display

$this->assign ("condition", $condition);

Direct $ value value= "{$condition}"

Array <volist name= "office_list" id= "VO" >

<tr><td>{$num ++}</td>

<td>{$vo .name}</td>

<td><a href= "__controller__/deleteofficejudge?id={$vo. ID}" onclick= "Del ()" > Delete </a></td> </tr></volist>

Iii. Configuration Files

$DB _config = Array (

' Db_type ' = ' mysql ',//database type

' Db_host ' = ' 127.0.0.1 ',//server address

' Db_name ' = ' evalute ',//database name

' Db_user ' = ' root ',//user name

' Db_pwd ' and ' = ',//password

' Db_port ' = 3306,//Port

' Db_prefix ' = ' think_ ',//database table prefix

' Db_charset ' = ' utf8 ',//Character Set

' Db_debug ' + TRUE,//Database debug mode can log SQL logs after opening

);

$URL _config = Array (

' Url_module ' = 0,

' Default_filter ' = ' Htmlspecialchars,trim ',

);

Return Array_merge ($DB _config, $URL _config);

Four, curd operation

Instantiation: D is going to instantiate the corresponding model, which is validated with it. M only to the database additions and deletions to check and change.

Data modification: Automatic authentication, token verification (anti-duplication commit) and auto-completion in the Create method. $User->create ($data), you can assign a value to $user first, or you can assign a value to the $data array. $User->add (); Write to the database, because the add does not pass data. You can also not create a direct add ($data). Save similar.

Data read: coherent operation; query conditions try to use array mode, which is a safer way;

$Model->where ("id=%d and Username= '%s '", Array ($id, $username))->select ();

Data deletion: $Form->delete (5), which deletes a primary key of 5

Removal tips for pages

Function del () {

if (!confirm ("Confirm to delete?") ")){

Window.event.returnValue = false;

}

}

Five, view model

namespace Home\model;

Use Think\model\viewmodel;

Class Contentmodel extends viewmodel{

Public $viewFields = Array (

' Paper ' =>array (' name '), ' pcontent ' =>array (' id ', ' qorder ', ' Paperid ', ' itemId ', ' _on ' = ' paper.id= ') Pcontent.paperid '),

' Question ' =>array (' subname ', ' option ' = ' Radio ', ' Startdesc ', ' enddesc ', ' _on ' = ' pcontent.qid=question.id ') ),

' Type ' =>array (' name ' = = ' type ', ' _on ' = ' type.id=question.type '),

' Item ' =>array (' name ' = ' itemname ', ' _on ' = ' pcontent.itemid=item.id '),

);

}

Vi. template replacement-special strings

__APP__: Will replace the current app's URL address (without domain name)

__MODULE__: Will replace the URL address of the current module (excluding domain name)

__CONTROLLER__ (__ or __url__ compatibility considerations): Will replace the current controller's URL address (without domain name)

__ACTION__: Will replace the current operation's URL address (without domain name)

__SELF__: Will replace the current page URL

__PUBLIC__: The common directory that will be replaced with the current site is usually/public/

Vii. File Upload

<input type= "file" name= "Photo"/>

$config = Array (

' MaxSize ' = 3145728,

' RootPath ' = './uploads/',

' Savepath ' = ',

' Savename ' = = Array (' uniqid ', '),

' exts ' = = Array (' jpg ', ' gif ', ' PNG ', ' jpeg '),

' Autosub ' = true,

' SubName ' = Array (' Date ', ' YMD '),

);

$upload = new \think\upload ($config);//instantiation of upload class

$info = $upload->upload ($_files[' photo ');

if (! $info) {//Upload error error message

$this->error ($upload->geterror ());

}else{//Upload successfully uploaded file information

echo $info [' Savepath ']. $info [' Savename '];

}

Eight, verification code

Public Function Verify () {

$Verify = new \think\verify;

$Verify->USEIMGBG = true;

Ob_clean ();//Discard the contents of the output buffer

$Verify->entry ();

}

Ix. Introduction of menu Files

<include file= "public/header.html"/>

Ten, when modified-radio box, check box

Single-Use EQ

<select name= "type" value= "{$question _info.type}" >

<volist name= "type_list" id= "T" >{$t. ID}

<eq name= "t.id" value= "$question _info.type" >

<option value= "{$t. ID}" selected= "selected" >{$t .name}</option>

<else/>

<option value= "{$t. ID}" >{$t .name}</option>

</eq>

</volist>

</select>

check box with in

<volist name= "Radio_list" id= "R" >

<in name= "r.id" value= "$question _info.option" >

<input name= "radio[" "type=" checkbox "value=" {$r. ID} "checked=" Checked ">{$r. Opname}

<else/>

<input name= "radio[]" type= "checkbox" value= "{$r. ID}" >{$r. Opname}

</in>

</volist>

Handling of Value after check box submission

foreach ($_post[' Radio ') as $key = = $value) {

$option = $option. $value. ",";

}

$data [' option '] = substr ($option, 0,strlen ($option)-1);

Split string

if ($question _info[' option ']! = null) {

$question _info[' option ' = Explode (",", $question _info[' option ');}

Xi. Verify that the user name already exists ajax+jquery

return value Echo json_encode ($user _list);

function CheckName () {

$.ajax ({

Type: "POST",

URL: "__controller__/testuser",

Data: "Uname=" +$ (' #uname '). Val (),

Success:function (msg) {

for (var mi in eval (' (' +msg+ ') ') {

Alert (mi+ "-and" +eval (' (' +msg+ ') ') [MI]);

// }

if (eval (' (' +msg+ ') ')! = null) {

$ (' #notice '). HTML ("already exists");

}else{

$ (' #notice '). HTML ("can be used");

}

}

});

}

12. Paging

$count = $type->count ();

$Page = new \think\page ($count, 2);

$Page-Setconfig (' header ', ' Total%total_row% ');

$Page-Setconfig (' first ', ' home ');

$Page-Setconfig (' Last ', ' Total%total_page% page ');

$Page-Setconfig (' prev ', ' prev ');

$Page-Setconfig (' Next ', ' next page ');

$Page-setconfig (' link ', ' indexpagenumb ');//pagenumb will replace the page number

$Page-Setconfig (' theme ', '%header%%first%%up_page%%link_page%%down_page%%end% ');

$show = $Page->show ();

$type _list = $type->order (' name desc ')->limit ($Page->firstrow. ', '. $Page->listrows)->select ();

$this->assign ("Type_list", $type _list);

$num = $Page->firstrow + 1;//serial number

$this->assign ("num", $num);

$this->assign ("page", $show);

<TR><TD colspan= "3" ><div>{$page}</div></td></tr>

Page with condition, the form form of a conditional query is submitted in get form

13. Custom Menu

Array in 1.js, note the a capitalization of array

var menus = new Array ();

Menus[0] = {"id": 1, "name": "Sport", "Ismenu": "1"}

Menus[1] = {"id": 2, "name": "Music", "Ismenu": "1"}

2.js information about the control where the event occurred

Onclick= "Del (This)"

del var myid = obj.id;

3.jquery fetching the value of the control

$ ("#xsq"). attr ("value", value);

$ ("#xsq"). Val ();

14. Commissioning

F12 look at the elements, see the network transmission

$this->show ("2333");

Var_dump ($a); PHP notation, dump ($a) works the same in thinkphp
