 private function updateThemeConfigMore($configMore, $moreInDb)

//echo empty($configMore);
// print_r($configMore); 
// return;

if (!empty($configMore['vars'])) {
            foreach ($configMore['vars'] as $mVarName => $mVar) { if (isset($moreInDb['vars'][$mVarName]['value']) && $mVar['type'] == $moreInDb['vars'][$mVarName]['type']) { $configMore['vars'][$mVarName]['value'] = $moreInDb['vars'][$mVarName]['value']; //数据库里有这个vars，并且类型一样，则更新这个值到配置文件数组里。 if (isset($moreInDb['vars'][$mVarName]['valueText'])) { $configMore['vars'][$mVarName]['valueText'] = $moreInDb['vars'][$mVarName]['valueText']; } } } } if (!empty($configMore['widgets'])) { foreach ($configMore['widgets'] as $widgetName => $widget) { if (isset($moreInDb['widgets'][$widgetName]['title'])) { $configMore['widgets'][$widgetName]['title'] = $moreInDb['widgets'][$widgetName]['title']; } if (isset($moreInDb['widgets'][$widgetName]['display'])) { $configMore['widgets'][$widgetName]['display'] = $moreInDb['widgets'][$widgetName]['display']; } if (!empty($widget['vars'])) { foreach ($widget['vars'] as $widgetVarName => $widgetVar) { if (isset($moreInDb['widgets'][$widgetName]['vars'][$widgetVarName]['value']) && $widgetVar['type'] == $moreInDb['widgets'][$widgetName]['vars'][$widgetVarName]['type']) { $configMore['widgets'][$widgetName]['vars'][$widgetVarName]['value'] = $moreInDb['widgets'][$widgetName]['vars'][$widgetVarName]['value']; if (isset($moreInDb['widgets'][$widgetName]['vars'][$widgetVarName]['valueText'])) { $configMore['widgets'][$widgetName]['vars'][$widgetVarName]['valueText'] = $moreInDb['widgets'][$widgetName]['vars'][$widgetVarName]['valueText']; } } } } } } return $configMore; }

 

问题关键在函数  updateThemeConfigMore($configMore, $moreInDb);   如果json文件有语法错误，$configMore没有正确读取。可能造成配置丢失。

在函数updateThemeConfigMore开头加如下代码输出json生成的数组

echo empty($configMore)."\n";
print_r($configMore); 
return;

 

模板更新，当json文件有语法错误（如少一个逗号）时，$configMore的值是空数组，empty($configMore)值返回1。

themes/w0s/portal/index
1

Array ( )

 

解决方案 updateThemeFiles函数里增加对json转换结果的判断，转换成功再更新数据库。

    {
        $dir                = 'themes/' . $theme; $themeDir = $dir; $tplFiles = []; $root_dir_tpl_files = cmf_scan_dir("$dir/*.$suffix"); foreach ($root_dir_tpl_files as $root_tpl_file) { $root_tpl_file = "$dir/$root_tpl_file"; $configFile = preg_replace("/\.$suffix$/", '.json', $root_tpl_file); $root_tpl_file_no_suffix = preg_replace("/\.$suffix$/", '', $root_tpl_file); if (is_file($root_tpl_file) && file_exists_case($configFile)) { array_push($tplFiles, $root_tpl_file_no_suffix); } } $subDirs = cmf_sub_dirs($dir); foreach ($subDirs as $dir) { $subDirTplFiles = cmf_scan_dir("$dir/*.$suffix"); foreach ($subDirTplFiles as $tplFile) { $tplFile = "$dir/$tplFile"; $configFile = preg_replace("/\.$suffix$/", '.json', $tplFile); $tplFileNoSuffix = preg_replace("/\.$suffix$/", '', $tplFile); if (is_file($tplFile) && file_exists_case($configFile)) { array_push($tplFiles, $tplFileNoSuffix); } } } foreach ($tplFiles as $tplFile) { $configFile = $tplFile .
