Question

我正在尝试为WordPress调试Collabpress插件。我对PHP的了解非常基础。

错误出现在一个名为cp-loader.php的php文件中。第88行的错误是意外的T_STRING，在下面突出显示。代码如下：

<?php
/*
Plugin Name: CollabPress
Plugin URI: http://collabpress.org/
Description: A Project Management Plugin for WordPress
Version: 1.3.1.2

}

define( 'CP_DASHBOARD', $cp_dashboard );

// CollabPress Core
require_once( 'includes/cp-core.php' );

 // activation hook
 register_activation_hook( __FILE__, 'cp_activation' );


/**
* Returns the query string of CollabPress values
* e.g. task=3&task-list=4
*/
function cp_frontend_querystrings() {

// grab any query strings that exist
if (isset($_SERVER['QUERY_STRING'])) {
$cp_all_querystrings = ( $_SERVER["QUERY_STRING"] ) ? $_SERVER["QUERY_STRING"] : '';
$cp_querystrings = explode( '&', $cp_all_querystrings );
} else {
$vars = $_GET;
}

//set pattern to strip out
$pattern = "/^cp|project|task-list|task|view|activity_page/";
$cp_qs_add = '';

foreach ((array) ( '$cp_querystrings as $cp_querystring') 
     -->    preg_match ( '$pattern, $cp_querystring ' ) {  <-- line 88: unexpected T_STRING error
        $cp_qs_add .= $cp_querystring .'&';
    }
}

if ( $cp_qs_add != '&' ) :
    return $cp_qs_add;
endif;

}

我用上面的箭头突出显示了错误。第88行出现意外错误＆＃34;意外T_STRING错误＆＃34;。

我能得到的任何帮助都会很棒。由于这是Github上的一个开源项目，如果有效，我也会在Github上发布一些内容。

典型的foreach循环如下所示： foreach($some_array as $item)其中$ some_array是一个数组。 Foreach迭代数组中包含的每个项目。

但在您的代码中，您使用的是String。通过文本'$cp_querystrings as $cp_querystring'周围的引号可见。这是代码中的主要错误。要解决此错误，您尝试将String转换为数组。这满足了Foreach循环的需求。但不幸的是，PHP对转换类型非常慷慨，所以真正的原因没有显示在您的错误消息中。

与preg_match ( '$pattern, $cp_querystring ' )几乎相同的问题。

你'$pattern, $cp_querystring '是一个字符串，因此preg_match只有一个参数。

下一个问题是preg_match缺少if子句。

我将解决方案纳入此修复程序：

foreach ($cp_querystrings as $cp_querystring) { if( preg_match ($pattern, $cp_querystring) > 0 ) { $cp_qs_add .= $cp_querystring .'&'; } }

您拥有的代码总体上已损坏，无法在任何PHP安装上运行。也许你已经收到了一个正在进行主动开发的版本？
