Smarty Custom Functions

Custom Function: <{method name}> creates a new file in Lib/plugins, named in a fixed way: function. Method name. php or block. Method name. php

1.<{literal}><{/literal}>

The data in the {literal} label area will be processed literally, typically around the javascript/css block, or the curly braces ' {', '} ' used in these languages will interfere with the template delimiter syntax. {literal} All symbols inside the {/literal} tag are not interpreted and are output as-is.

For example: After adding tags to the main.html code:

Operation Result:

2.{html_select_date}

The custom function {html_select_date} is used to create a date drop-down list, which can display any month or day. Parameters not described in the following list are displayed as key value pairs of name/value in the corresponding year, month, Day <select> label.

<div><{html_select_date}></div>

Display interface:

After adding parameters:

<div><{html_select_date start_year= ' 1990 ' end_year= ' 2020 ' month_format= '%m '}></div>

Display interface:

3. Online Search: Color control function.color.php (need to introduce file jscolor.js)

1<?PHP2     3     /**4 * Color Control5      * 6 * @param $name control name7 * @param $value selected value8 * <{color name= ' titlecolor ' value= ' ff00ff '}>9      */Ten     functionSmarty_function_color ($args,$smarty) { One  A         $name=$args[' Name ']; -         $value= !Empty($args[' Value ']) ?$args[' Value ']: ' 000000 '; -      the         if(!defined(' Color_init ')) { -             Define(' Color_init ', 1); -             $str= ' <script src= '. /js/jscolor/jscolor.js "></script>"; -                 +         } -         $str. = ' <input class= ' "Color" style= "Width:48px;height:16px;overfrom:hidden" name= "'.$name. ' "Value=".$value. ' "/> '; +      A         return $str; at}

View CodeCalling method on the front end: <div><{color name= ' AA '}></div>

After operation: can be arbitrarily selected

4.{block} BLOCK: Editor (on-line) {Block}{/block} appears in pairs for example: Introduction: block.textarea.php (also CKEditor folder) in the front-end call Method://No parameters:
<{textarea}>
<{/textarea}> after Operation:

Add parameter:
<{textarea name= ' text ' toolbar= ' full ' color= ' Purple ' height= ' '}> '
<{/textarea}> after Operation:

5. Practice the Custom Function: Write method to change the main.html type to show the specific content new file function.typename.php

1<?PHP2 3 //parameters: 1. $args array, must have4 functionSmarty_function_typename ($args)5 {6     //fetch the code value passed in.7     $code=$args["Code"];8     if($code==0)9     {Ten         return"Judgment question"; One         } A     Else if($code==1) -     { -         return"Single Choice"; the         } -     Else -     { -         return"Multi-choice"; +         } -}

After the front-end call method: Main.html <td><{typename code= $v [5]}></td> run:

6. Practice Custom Functions Block: Define block functions to change the style of deleting modified new file function.typename.php (four parameters required)

1<?PHP2 //$args is the parameter that the user can pass in $a the function is the start and end3 functionSmarty_block_fontstyle ($args,$content,$smarty,$a)4 {5     $color=$args["Color"];6     $size=$args["Size"];7     8     //The block function executes 2 times and executes once at the start and end tags9 //To prevent repeated execution, need to be judgedTen     if(!$a)//If the end tag is executed One     { A         return"<span style= ' background-color:{$color};font-size:{$size}px ' >{$content}</span> "; -          -     } the}

Calling methods on the front end: main.html

1   <!--define block functions to change the style of deleting modifications-2      <td>3      <{fontstyle color= ' yellow ' size= '}> 4     <a href= "delete.php?code=<{$v[0]}>" > Delete </a>5     <a href= "update.php? code=<{$v[0]}> "> Modify </a>6     <{/fontstyle}>7     </ Td>

After running: (the middle Operation accidentally deleted a row of data)

7. configuration file: Config files creates a new file in the Configs folder, and the file name ends with. conf For example: The test.conf configuration file is loaded into the template via the built-in function {config_load} or the Configload () function of the API. Example: Write a div on the front main.html and change its style with the configuration file:

<div> below is a list of topics </div>

Create a new file in the Configs folder style.conf

On the front main.html:

1. Read the configuration file: <{config_load file= "style.conf"}>

2. Introducing variables with <{#变量名 #}>: <div style= "font-size:<{#size #}>px; color:<{#color #}> "> Below is a list of topics </div>

If: The same style is defined in style.conf, it is distinguished by a block, defined in the following way: [Block name]

In front of main.html: Give Config_load the second variable section

<{config_load file= "style.conf" section= "one"}>
<div style= "font-size:<{#size #}>px; color:<{#color #}> "> Below is a list of topics </div>

<{config_load file= "style.conf" section= "Both"}>
<div style= "font-size:<{#size #}>px; color:<{#color #}> "> Below is a list of topics </div>
