To add a plug-in to the oneThink background:

Version: V1.1.141212)

I am not lazy and keep records of every step.

1. go to the background and create a plug-in

I created an indexFooter for the hook here, because I only need to display the link at the bottom of the front-end homepage. We have checked all the above items. as to the differences, you can create several examples to identify whether the generated files are the same. OK! Here, our friendship link plug-in has been created! Click "OK ". (If you do not enter a custom template or something here, I will demonstrate the effect of adding a custom template in the next article)

2. click "install". find the newly installed Links plug-in and click "set". you will see that it has the default "enable random" option, we don't care about it here, because we can't use it, and we will delete it later. After the plug-in is installed, you can see the new "link" in the left-side navigation bar "installed plug-in background"

3. when we click "link" in the left-side navigation bar, you will find an error, which means that a table does not exist. Yes. we just created a plug-in. if data is stored in the database, you need to create a table. The database is not directly built here, because it is very unfriendly to do so. Then we can find the function for installing the plug-in and create a database when installing the plug-in. First, all the system plug-ins are stored in the root directory/Addons/Folder. open this folder and we can see a Links folder. this is the plug-in we just created. a plug-in corresponds to a folder. Open the Links folder, which contains 2 files and 2 folders.

4. now oneThink is more and more concise. people who do not understand PHP can create plug-ins, and you will find out later. Of course, if you have your own ideas and don't want to limit them to official restrictions, you should learn php well.

5. open the plug-in entry File: LinksAddon. class. php contains a LinksAddon class. let's analyze this file first.

Here, I changed the model value of the $ admin_list array to links to correspond to the plug-in. Next, add the statement for creating a database in the install method, so that we will create a new database when installing the plug-in. my code is as follows:

Public function install () {// method for installing the plug-in // 1. add the data table $ model = D (); $ db_prefix = C ('Db _ prefix '); $ table_name = "{$ db_prefix} links"; $ SQL = <
Execute ($ SQL); // execute the SQL statement // 2. return true, indicating that the plug-in is successfully installed and return true ;}

I have omitted a lot of details and made them perfect.

6. since a new table is created when the plug-in is installed, we need to delete the table when uninstalling the plug-in. otherwise, problems may occur when the plug-in is installed next time. Therefore, the uninstall method code is as follows:

Public function uninstall () {// method for uninstalling the plug-in $ model = D (); $ db_prefix = C ('Db _ prefix '); $ table_name = "{$ db_prefix} links"; $ SQL = "DROP TABLE IF exists '". $ table_name. "';"; $ model-> execute ($ SQL); // execute the SQL statement return true ;}

Okay, it's almost done here. Save the LinksAddon. class. php file and it should be displayed normally. let's take a look. Go to the plug-in list, uninstall the Links plug-in, and then reinstall it. Click "link" in the left-side menu.

The reason why the list can be displayed is that the system has a default template. in the \ Application \ Admin \ View \ Addons folder, interested templates can be used to study these template files. In this example, the template adminlist.html should be replaced, do you want to modify it in the template? Careful students may have noticed that the $ admin_list array in the LinksAddon. class. php file is configured. others can see the annotations below. here we will detail the arrays associated with list_grid. The links data table we just created has fields such as id, title, and link. you can add any fields in this list. The code here is as follows:

'List _ grid' => array (// Here, the header name and model displayed in the table except the id serial number are the same as those in the table. function and link 'Title: website name' are supported ', 'link: link', 'Summary: description', 'create _ time | time_format: add time', // time_format is a function that formats the time, you can also write 'Id: Operation: [EDIT] | EDIT, [DELETE] | delete' for any function you want to use elsewhere '),

Save and refresh the list of background links

Click "add" to add a link. you will find that there is only one name field. Open the Model/LinksModel. class. php file. here I will explain the two built-in arrays separately. for details, refer to the comments in the code below.

Class LinksModel extends Model {public $ model = array ('title' => '', // added the 'Template _ add' => ''prompt for [title], edit [title], and delete [title '', // custom new template custom html edit.html will read the template 'Template _ edit' => ''in the plug-in root directory '', // custom editing Template html 'search _ key' => '', // field name for search. the default value is title 'extend' => 1, // check whether the "add" or "delete" buttons are displayed in the background List. if the value is 0, the value 1 is not displayed ); public $ _ fields = array ('id' => array ('name' => 'id', // field name, corresponds to the database field 'title' => 'id', // displays the title 'type' => 'num', // field type: num, string, textarea, datetime, bool, select, radio, checkbox, editor, picture (cover), file (attachment), 'remark' => '', // remarks, equivalent to tip 'is _ Show' => 3 in the configuration, // 1-always show 2-add show 3-edit show 0-not show 'value' => 0, // default value). // The following example shows how the select field displays radio and checkbox. Similarly, 'type' => array ('name' => 'type ', 'title' => 'type', 'type' => 'select', 'remark' => 'Select the type ', 'Is _ Show' => 1, 'Extra '=> '0: link, 1: Site', 'value' => 0, 'is _ must '=> 1 ,),);}

OK. The final result is as follows:

Add a piece of data:

Here we need to display the specific pictures and images, and customize the adminlist.html template. For more information about custom templates, see the next article. You can write a function to read data from the database, and then call the hook as needed at the front-end. If a template is required, the template is parsed in the hook function. The hook call format is generally:

{: Hook ("hook name"), "[parameter. Directly written as this {: hook ("hook name ")}

By now, the default system template is used to build your own plug-ins step by step. is it very easy, just like filling in blank questions, as long as you fill in the blanks according to its rules, it will be OK.

The above is all the content of this article. I hope it will help you learn PHP programming.
