HTML 輔助函數(shù)?
HTML 輔助函數(shù)包含的函數(shù)輔助 HTML 運(yùn)行。
通用函數(shù)?
下面的函數(shù)是通用的:
-
img
([$src = ''[, $indexPage = false[, $attributes = '']]])? param mixed $src: Image 原始碼數(shù)據(jù) param bool $indexPage: 是否像路由的 URI 字符串處理 $src param mixed $attributes: HTML 屬性 returns: HTML image tag rtype: string 讓你創(chuàng)建 HTML <img /> tags. 第一個參數(shù)包含 image 原始碼。事例:
echo img('images/picture.jpg'); // <img src="http://site.com/images/picture.jpg" />
有一個可選擇的第二參數(shù)是特定的 true/false 值并規(guī)定如果 src 將經(jīng)由
$config['indexPage']
被添加到地址并創(chuàng)建有明確說明的頁面。推測起來,假如你正在使用一個 media 控制器那將是自以為是的:echo img('images/picture.jpg', true); // <img src="http://site.com/index.php/images/picture.jpg" alt="" />
此外,組合數(shù)組能被作為第一參數(shù)傳達(dá),為了完成控制額外的所有屬性和值。 如果不提供 alt 屬性,CodeIgniter 將產(chǎn)生空字符串。
例如:
$imageProperties = [ 'src' => 'images/picture.jpg', 'alt' => 'Me, demonstrating how to eat 4 slices of pizza at one time', 'class' => 'post_images', 'width' => '200', 'height' => '200', 'title' => 'That was quite a night', 'rel' => 'lightbox' ]; img($imageProperties); // <img src="http://site.com/index.php/images/picture.jpg" alt="Me, demonstrating how to eat 4 slices of pizza at one time" class="post_images" width="200" height="200" title="That was quite a night" rel="lightbox" />
-
link_tag
([$href = ''[, $rel = 'stylesheet'[, $type = 'text/css'[, $title = ''[, $media = ''[, $indexPage = false]]]]]])? 參數(shù): - $href (string) – 鏈接文件的原始碼
- $rel (string) – 關(guān)系類型
- $type (string) – 關(guān)系文件夾的類型
- $title (string) – 鏈接主題
- $media (string) – 媒體類型
- $indexPage (bool) – 是否像路由的 URI 字符串處理 $src
返回: HTML link tag
返回類型: string
讓你創(chuàng)建 HTML <link /> tags. 這對樣式表鏈接是有用的,和其他鏈接一樣。參數(shù)是 href ,帶著可選擇的 rel, type, title, media 和 indexPage.
indexPage 是 boolean 值并規(guī)定如果 href 將經(jīng)由
$config['indexPage']
被添加到地址并創(chuàng)建有明確說明的頁面。例如:
echo link_tag('css/mystyles.css'); // <link href="http://site.com/css/mystyles.css" rel="stylesheet" type="text/css" />
更多示例:
echo link_tag('favicon.ico', 'shortcut icon', 'image/ico'); // <link href="http://site.com/favicon.ico" rel="shortcut icon" type="image/ico" /> echo link_tag('feed', 'alternate', 'application/rss+xml', 'My RSS Feed'); // <link href="http://site.com/feed" rel="alternate" type="application/rss+xml" title="My RSS Feed" />
間隔地,為了完全控制額外的所有屬性和值組合數(shù)組能被傳達(dá)到
link_tag()
函數(shù):$link = [ 'href' => 'css/printer.css', 'rel' => 'stylesheet', 'type' => 'text/css', 'media' => 'print' ]; echo link_tag($link); // <link href="http://site.com/css/printer.css" rel="stylesheet" type="text/css" media="print" />
-
script_tag
([$src = ''[, $indexPage = false]])? 參數(shù): - $src (mixed) – JavaScript 文件的原始碼名稱
- $indexPage (bool) – 是否像路由的 URI 字符串處理 $src
返回: HTML script tag
返回類型: string
讓你創(chuàng)建 HTML <script></script> tags. 參數(shù)是 src, 與可選的 indexPage 一起.
indexPage 是 boolean 值并規(guī)定如果 src 將經(jīng)由$config['indexPage']
被添加到地址并創(chuàng)建有明確說明的頁面。例如:
echo script_tag('js/mystyles.js'); // <script src="http://site.com/js/mystyles.js" type="text/javascript"></script>
間隔地,為了完全控制額外的所有屬性和值組合數(shù)組能被通過
script_tag()
函數(shù):$script = ['src' => 'js/printer.js']; echo script_tag($script); // <script src="http://site.com/js/printer.js" type="text/javascript"></script>
-
ul
($list[, $attributes = ''])? param array $list: 目錄登錄 param array $attributes: HTML 屬性 returns: HTML-formatted 無序目錄 rtype: string 容許你從簡單或者多倍空間的數(shù)組產(chǎn)生無序 HTML 目錄。事例::

上文的編碼將產(chǎn)生這樣地 HTML 前端代碼:
<video src="test.mp4" controls> Your browser does not support the video tag. </video> <video src="http://www.codeigniter.com/test.mp4" controls> <track src="subtitles_no.vtt" kind="subtitles" srclang="no" label="Norwegian No" /> <track src="subtitles_yes.vtt" kind="subtitles" srclang="yes" label="Norwegian Yes" /> Your browser does not support the video tag. </video> <video class="test" controls> <source src="movie.mp4" type="video/mp4" class="test" /> <source src="movie.ogg" type="video/ogg" /> <source src="movie.mov" type="video/quicktime" /> <source src="movie.ogv" type="video/ogv; codecs=dirac, speex" /> <track src="subtitles_no.vtt" kind="subtitles" srclang="no" label="Norwegian No" /> <track src="subtitles_yes.vtt" kind="subtitles" srclang="yes" label="Norwegian Yes" /> Your browser does not support the video tag. </video>

-
doctype
([$type = 'html5'])? 參數(shù): - $type (string) – Doctype 名字
返回: HTML DocType tag
返回類型: string
幫助你產(chǎn)生 document type 聲明, 而 DTD’s. HTML 5 是默認(rèn)使用的,但是許多 doctypes 是通用的。
事例:
echo doctype(); // <!DOCTYPE html> echo doctype('html4-trans'); // <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
接下來的是重定義 doctype 選擇的目錄。 這些是可設(shè)置的, 被從 application/Config/DocTypes.php 出棧,或者在你的 .env 結(jié)構(gòu)里它們能被加載。
