我有一个产品列表,我想添加一个"立即付款"按钮,以便我可以让我的客户通过Paypal支付.
我已经阅读了文档,但无法找到如何执行此操作.我可以添加多个项目,但这不会很方便,因为我已经有要处理的项目列表.我还需要结帐流程来逐项列出订单,所以"现在购买"1个价格也不好.
任何帮助赞赏的人,我试过(没有运气):

一切都很好,除了callgraph.php文件,它返回:
failed to shell execute cmd=" dot -Tpng"
所以我检查并没有安装dot实用程序,所以我安装它.
它似乎从命令行运行良好所以我再次运行scritp,同样的错误:
failed to shell execute cmd=" dot -Tpng"
xhprof文档说明:
the callgraph image visualization ([View Callgraph]) feature relies on the presence of Graphviz "dot" utility in your path.
但我不明白我现在需要做什么,特别是"路径中的效用"部分
任何帮助表示感谢,谢谢你们
我一直在看php反射方法,我想要做的是在方法打开之后和任何返回值之前注入一些代码,例如我想要更改:
function foo($bar)
{
$foo = $bar ;
return $foo ;
}
并注入一些代码,如:
function foo($bar)
{
//some code here
$foo = $bar ;
//some code here
return $foo ;
}
可能？
我安装了Mail_Mime包.
include('Mail.php');
include('Mail/mime.php');
我收到以下错误:
Warning: include(Mail.php) [function.include]: failed to open stream: No such file or directory in /var/www/vhosts/domain.co.uk/httpdocs/mail_mime/index.php on line 2
Warning: include() [function.include]: Failed opening 'Mail.php' for inclusion (include_path='.:/usr/lib/php/PEAR:/usr/lib/php/modules') in /var/www/vhosts/domain.co.uk/httpdocs/mail_mime/index.php on line 2
Warning: include(Mail/mime.php) [function.include]: failed to open stream: No such file or directory in /var/www/vhosts/domain.co.uk/httpdocs/mail_mime/index.php on line 3

这2个文件肯定在文件夹中:
/usr/lib/php/PEAR/Mail.php
/usr/lib/php/PEAR/Mail/mime.php
pear list告诉我安装了所需的软件包,并且没有遗漏的依赖项
我需要将所有上传的文件更改为72 dpi.我正在使用php imagick扩展.
继承人我试过的(我使用的图像是300dpi):
$image = new Imagick();
$image->setResolution(72,72) ;
$image->readImage($img);
$image->resampleImage (72,72,imagick::FILTER_UNDEFINED,1);
$image->writeImage($target)
这似乎没什么.图像正在上传,但保持在300dpi
可能重复:
jQuery中最近的祖先节点
HTML:
<div class="post">
<h2><a href="#" title="">Pellentesque</a></h2>
<p><a href="#" title="" class="more">More</a></p>
</div>
jQuery的
$('.more').bind("hover", function(){
$(this).parent('.post').hide() ;
});
在悬停(.more)我想隐藏帖子,但如果我使用parents()它没有任何作用,而是删除页面上的所有.posts
任何帮助赞赏
我怎样才能在php中访问属性值:
[photos] => SimpleXMLElement Object
(
[@attributes] => Array
(
[page] => 1
[pages] => 1
[perpage] => 24
[total] => 18
)
我尝试过以下方法:
$photos->@attributes['total'] ;
$photos->{'@attributes'}['total'] ;
以及这方面的许多变化
我想用:
function list(args);
但这list是一个保守的词.
我可以从PHP中删除列表功能,禁用它,还是以其他方式？
