如何将 manifest.json 集成到 wordpress 主题中

问题描述

我在网上搜索过，但我看到的结果不够清楚。

通过将此代码添加到 functions.PHP 文件中，我能够将 manifest.json 文件添加到我的 wordpress 主题中。

//manifest file
add_action( 'wp_head','inc_manifest_link' );

// Creates the link tag
function inc_manifest_link() {   
        echo '<link rel="manifest" href="'.get_template_directory_uri().'/manifest.json">';
}

manifest.json 应该是这样。

但是我希望在清单文件中使用一些 theme_mod 函数。没有 PHP，我就做不到。

无论如何都可以在 manifest.json 文件中编写 PHP 代码。

提前致谢。

解决方法

所以你可以这样做：

<?php
    $filename = "manifest.json";

    // Grab contents and decode them into an array
    $data = json_decode(file_get_contents($filename),true);

    //this is where you're adding your content so below you can write to the file
        //Creating new var 
        //(make sure no var has the name "['newnewname']" unless you want to edit it)
        $data['newname'] = 'Adding NEW contents';

        //Creating new 2 dimensional array
        $data['newname'] = array("another1" => "val1","another2" => "val2");

        //adding content to an existing 2 dimensional array
        $data['exists'] += array("another1" => "val1","another2" => "val2");

        //adding content to an existing 3 dimensional array
        $data['exists']['name'] += array("another1" => "val1","another2" => "val2");

        //adding content to an existing 4 dimensional array
        $data['exists']['name']['name'] += array("another1" => "val1","another2" => "val2");

    // encode back into json
    $jencode = json_encode($data);

    // write over file with new contents
    $fopen = fopen($filename,"w");
    if(fwrite($fopen,$jencode)){
        echo('Success!<hr>');
        echo(file_get_contents($filename));
    }
    fclose($fopen);

这是一个活生生的例子（删除了 fopen/write/read 的东西）：
