• 与PHP DOM合作—— html操纵。它对产出超文本标记确实非常有效(至少防止密码的逻辑和标志)。

但是,为了产生50条html标记线,必须在PHP中写出约200条线:(............)。

例:

............

$signup_form = $document->createElement( form );
$signup_form->setAttribute( id ,  signup_form );
$signup_form->setAttribute( action ,  registration/signup.php );
$signup_form->setAttribute( method ,  post );
$su_fname_label = $document->createElement( label );
$su_fname_label->setAttribute( for ,  fname );
$su_fname_label_content = $document->createTextNode( Name );
$su_fname_label->appendChild($su_fname_label_content);
$su_fname_textbox = $document->createElement( input );
$su_fname_textbox->setAttribute( name ,  fname );
$su_fname_textbox->setAttribute( class ,  valid );
$su_fname_textbox->setAttribute( placeholder ,  Please enter your name );
$su_fname_textbox->setAttribute( type ,  text );

......

如你所知,它只是形式的一个要素。 Imagine, 如果以超文本形式出现5个要素,则《特区法典》将十分庞大。我不禁要问,是否通过一劳永逸地确定多重属性来加以排除? 任何建议?

Answer 1

Why don t you just output HTML and enabled output buffering. Then you can filter out the output using the tidy extension and be sure that your output HTML is valid, while still going as fast as writing pure HTML.

尽管如此,正如@Gordon建议的那样:

简言之,对方案编写者(x)html来说并不合适。更像一个邮政处理员。

你们为什么利用OMD来产生html的产出? 没有任何办法使人力部<><>>>!

Usually you just use PHP for templating. Create a separate file like so:

<?php // template.php
echo  <!DOCTYPE html> ,"
";
?>
<html>
    <head>
    <meta charset="utf-8">
    <title><?=htmlspecialchars($title, ENT_NOQUOTES,  utf-8 )?></title>
    </head>
    <body>
       <form id="signup_form" action="registration/signup.php" method="post">
           <label for="fname">Name</label>
           <input id="fname" name="fname" class="valid" placeholder="Please enter your name" type="text">
       </form>
    </body>
</html>

然后使用模板功能:

function render($__filename, $__data) {
    extract($__data, EXTR_SKIP);
    ob_start();
    include $__filename;
    return ob_get_clean();
}

将贵方的模板从您的法典中删除:

do_something();
$templatedata = array( title => The Title );
$html = render( template.php , $templatedata);

如果你们想要的是没有意识的东西(这是确保知情和正确理解的伟大想法!),那么你可以使用XSLT或第三方模板发动机,如PHPTAL。

Depending on your need for speed and if you re able to use caching and the like, a library such as phpQuery could be of use.

缩略语 Query to PHP and has same globaltility and simplicity as 。然而,从我的经验来看,这并不像我在制定法典时一样快(但I <>没有<>,但进行过任何彻底的测试,这只是一种感觉)。

The code you ve given as an example could be expressed along these lines with phpQuery (untested):

$form = pq ( <form /> )
          ->attr (array (
                     id  =>  signup_form ,
                     action  =>  registration/signup.php ,
                     method  =>  POST ,
                  ));
$label = pq ( <label /> )
          ->html ( Name )
          ->attr ( for ,  fname )
          ->appendTo ($form);
$text = pq ( <input /> )
          ->attr (array (
                     name  =>  fname ,
                     data-placeholder  =>  Please enter your name ,
                     type  =>  text ,
                  ))
          ->addClass ( valid )
          ->appendTo ($label);

I ve written it with the formatting I prefer, and it s slightly more lines than in the code you ve supplied; but it could easily be reduced to 5-10 or so lines with maintained readability, if you prefer more compact coding. At any rate, I find it quite a lot easier to read and you don t have to write quite so much DOM code in order to generate quite a lot of HTML code.

此外,考虑到<代码>php 质量采用与<代码>j相同的总结概念 Query , an unwrapped node, for example $form in the above Code, is a regular MNode, 但pq()不在此列。这使你在使用<条码>、质量<>/代码>方便例行或<条码>的“基本”功能方面有很大的灵活性。 PHP DOM。

我在我认识到自己不易读之前,就使用了你做的事情。你们必须分析该守则,以确定正在建立哪些标志。更难以维持。正如你所说的那样,在形式上增加一个单一领域需要相当的守则范围,要作出改变,就必须通过该守则来挖掘。我同意,要把你的购买力平价逻辑与你的标记分开;然而,根据你试图做些什么,有更好的办法保持你的代码清扫。

如果不进入第三方解决办法,你可以:

Load Markup from a separate file into a DOM Object for further edited.

利用PHP作为模板发动机,其设计方法是将PHP列入你的标记。正如Shrapnel上校非常雄辩地解释:“如果你把业务逻辑与整个网站的列报逻辑分开,则支持任何规模和结构的模板......”。

http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc”rel=“nofollow”>。它虽然不是最佳选择,但比纯粹的基于OM的方法更容易阅读。

$signup_form = <<<EndHTMLForm
<form id="signup_form" action="registration/signup.php" method="post">
    <label for="fname">Name</label>
    <input name="fname" class="valid" placeholder="Please enter your name" type="text">
</form>
EndHTMLForm;

我这里的目的就是要引导你从第三方解决办法中获取<>><>><>>>,而是要说明在平原-万里吉斯P.HP采取的替代办法。电力局是ver。它当然有可贵的优点,但从rat子的t子中打上标记。
