June 5 Smarty Custom function

Custom Function: <{method name}>

In the HTML page can be directly assigned to: (no function just know can)

<{$a = "Hello"}>
<div><{$a}></div>

Display effect: Hello

1.<{literal}><{/literal}> built-in functions

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. If you need to use a template tag in the {literal} block, consider escaping the separate delimiter with {Ldelim}{rdelim}.

The function is when the left and right delimiter {} In case of mixing with function, but it is not used now <{}>

For example

 <{literal}> <{foreach   $shuju  as   $v }><tr> <td> <{ $v  [1]|truncate:10: "* * *" |fontcolor:green}></td> <td> <{ $v  [2]|fontcolor}></td> <td><{ $v  [3]|kmname}></td> <td><{ $v  [4]|nandu}></ td> <td><{ $v  [5]|type}></td> <td><a href= "Shanc Hu.php?code=<{ $v  [0]}> "> Delete </a>&nbsp;&nbsp;<a href = "Xiugai.php?code=<{ $v  [0]}>" > Modify </a></td> </tr> <{/foreach }><{/literal}> 

The result of the output at this time is: (not parsed as output)

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.

For example 1:<div><{html_select_date}></div> (in case of no write-in parameters)

The returned result is:

For example 2:<div><{html_select_date start_year= ' 1990 ' end_year= ' 2020 ' month_format= '%m '}></div> (write-in parameter)

The returned result is:

3. Online Search: Color controlCreate a new function.color.php (function) in Www/smarty0603/plugins, and also introduce the Jscolor.js file

<?PHP/** * Color Control * * @param $name Control name * @param $value Check value * <{color name= ' titlecolor ' value= ' ff00ff '}>*/    functionSmarty_function_color ($args,$smarty) {        $name=$args[' Name ']; $value= !Empty($args[' Value ']) ?$args[' Value ']: ' 000000 '; 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. ' "/> '; return $str; }

Previous HTML code: <div><{color name= ' AA '}></div>

return Result:

4.{block} BLOCK: Editor (online search){Block}{/block} paired appearance

Common method functions only need to write a good, but think block function has beginning and end

New block.textarea.php

<?PHP/** * editor * @param int $textareaid * @param int $toolbar have basic full and desc three types * @param int $color Editor Color * @param string $alowuploadexts allow upload type * @param string $height Editor Height * @param string $disabled _page whether paging is disabled and Sub-headings*/    functionSmarty_block_textarea ($args,$content,$smarty, &$repeat) {    //Public static function editor ($textareaid = ' content ', $toolbar = ' basic ', $height = $, $color = ', $up =true) {    if(!$repeat) {            $textareaid= !Empty($args[' Name ']) ?$args[' Name ']: ' content '; $toolbar= !Empty($args[' toolbar ']) ?$args[' toolbar ']: ' Basic '; $height= !Empty($args[' Height ']) ?$args[' Height ']: ' 200 '; $color= !Empty($args[' Color ']) ?$args[' Color ']: '; $up= !Empty($args[' Up ']) ?$args[' Up ']:true; $str= ' <textarea name= '.$textareaid.‘" > '.$content.‘ </textarea> '; if(!defined(' Editor_init ')) {            $str. = ' <script type= ' text/javascript ' src= '. /js/ckeditor/ckeditor.js "></script>"; Define(' Editor_init ', 1); }            if($toolbar= = ' Basic ') {            $toolbar= "[' Bold ', ' Italic ', ' underline ', ' Strike ', ' numberedlist ', ' BulletedList ', ' textcolor ', ' BGColor ', ' Link ', ' Unlink ', '-', ' Image ', ' Flash ', ' Table ', ' Smiley ', ' Specialchar '],[' removeformat '], \ r \ n"; } ElseIf($toolbar= = ' Full ') {           $toolbar= "[' Source ', '-', ' Templates '], [' Cut ', ' Copy ', ' Paste ', ' pastetext ', ' Pastefromword ', '-', ' Print '], [' Un Do ', ' Redo ', '-', ' Find ', ' Replace ', '-', ' selectall ', ' Removeformat '],[' showblocks '],[' Image ', ' Capture ', ' Flash '],[' Maximize '], '/', [' Bold ', ' Italic ', ' underline ', ' Strike ', '-'], [' Subscript ', ' superscript ', ' -'], [' numberedlist ', ' BulletedList ', '-', ' outdent ', ' Indent ', ' Blockquote '], [' Justifyleft ', ' Justifycen ' Ter ', ' justifyright ', ' Justifyblock '], [' Link ', ' Unlink ', ' Anchor '], [' Table ', ' horizontalrule ', ' Smiley ',            ' Specialchar ', '/', [' Styles ', ' Format ', ' Font ', ' FontSize '], [' TextColor ', ' BGColor '], [' Attachment '],\r\n"; } ElseIf($toolbar= = ' desc ') {            $toolbar= ' [' Bold ', ' Italic ', '-', ' numberedlist ', ' BulletedList ', '-', ' Link ', ' Unlink ', '-', ' Image ', '-', ' Source '],\r\n '; } Else {            $toolbar= ' '; }        $str. = "<script type=\" text/javascript\ ">\r\n"; $str. = "Ckeditor.replace ('$textareaid‘,{"; $str. = "height:{$height},"; if($color) {            $str. = "Extraplugins: ' Uicolor ', Uicolor: '$color‘,"; }        /*if ($up) {$str. = "Filebrowserimageuploadurl: '". B_url. "            /upimage ', "; $str. = "Filebrowserflashuploadurl: '". B_url.

5. Practice writing the function yourself (before the regulator is now based on the method)

New File function.tyname.php

<?PHPfunctionSmarty_function_tyname ($args){    //fetch the code value passed in.    $code=$args["Code"]; $db=NewMysqli ("localhost", "root", "" "," MyDB "); $sql= "Select type from leixing where code = ' {$code}‘"; $result=$db->query ($sql); $attr=$result-Fetch_row (); return $attr[0];}

View Code

HTML code for the previous paragraph: <td><{tyname code= $v [5]}></td>

Display effect: Previous effect:

6. Practice Custom Functions Block: Define block functions to change the style of deleting changesnew File block.fontstyle.php (four parameters required)

<?PHPfunctionSmarty_block_fontstyle ($args,$content,$smarty,$a){    //$args: Is the parameter that the user can pass in, $content: the content contained within the block function; $a: Refers to the beginning and end of a function    $color=$args["Color"]; $size=$args["Size"]; //The block function executes 2 times, each time the start and end tags are executed//To prevent repeated execution, which needs to be judged    if(!$a)//If the end tag is executed    {         return"<span style= ' background-color:{$color};font-size:{$size}px ' >{$content}</span> "; }}

Front-end HTML code:

  <TD>    <{FontStyleColor= ' Yellow 'size= ' + '}>    <ahref= "shanchu.php?code=<{$v [0]}>">Delete</a>&nbsp;&nbsp;<ahref= "xiugai.php?code=<{$v [0]}>">Modify</a>    <{/fontstyle}>    </TD> 

Display effect:

7. Configuration file: Config filesCreate a new file in the Configs folder, with the file name ending 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 in the front main.html, change its style with a configuration file: The new style.conf in the configs configuration file looks like this:

Front-end HTML code:

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>

Display effect:

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>

The effect is as follows:

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

The effect is as follows:
